A Mechanistic Model of Waterfall Plunge Pool Erosion into Bedrock

Science.gov (United States)

Scheingross, Joel S.; Lamb, Michael P.

2017-11-01

Landscapes often respond to changes in climate and tectonics through the formation and upstream propagation of knickzones composed of waterfalls. Little work has been done on the mechanics of waterfall erosion, and instead most landscape-scale models neglect waterfalls or use rules for river erosion, such as stream power, that may not be applicable to waterfalls. Here we develop a physically based model to predict waterfall plunge pool erosion into rock by abrasion from particle impacts and test the model against flume experiments. Both the model and experiments show that evolving plunge pools have initially high vertical erosion rates due to energetic particle impacts, and erosion slows and eventually ceases as pools deepen and deposition protects the pool floor from further erosion. Lateral erosion can continue after deposition on the pool floor, but it occurs at slow rates that become negligible as pools widen. Our work points to the importance of vertical drilling of successive plunge pools to drive upstream knickzone propagation in homogenous rock, rather than the classic mechanism of headwall undercutting. For a series of vertically drilling waterfalls, we find that upstream knickzone propagation is faster under higher combined water and sediment fluxes and for knickzones composed of many waterfalls that are closely spaced. Our model differs significantly from stream-power-based erosion rules in that steeper knickzones can retreat faster or more slowly depending on the number and spacing of waterfalls within a knickzone, which has implications for interpreting climatic and tectonic history through analysis of river longitudinal profiles.

On the waterfall behavior in hybrid inflation

We revisit the hybrid inflation model focusing on the dynamics of the waterfall field in an analytical way. It is shown that inflation may last long enough during the waterfall regime for some parameter regions, confirming the claim of Clesse. In this case the scalar spectral index becomes red, and can fall into the best fit range of the WMAP observation.

Self-formed waterfall plunge pools in homogeneous rock

Science.gov (United States)

Scheingross, Joel S.; Lo, Daniel Y.; Lamb, Michael P.

2017-01-01

Waterfalls are ubiquitous, and their upstream propagation can set the pace of landscape evolution, yet no experimental studies have examined waterfall plunge pool erosion in homogeneous rock. We performed laboratory experiments, using synthetic foam as a bedrock simulant, to produce self-formed waterfall plunge pools via particle impact abrasion. Plunge pool vertical incision exceeded lateral erosion by approximately tenfold until pools deepened to the point that the supplied sediment could not be evacuated and deposition armored the pool bedrock floor. Lateral erosion of plunge pool sidewalls continued after sediment deposition, but primarily at the downstream pool wall, which might lead to undermining of the plunge pool lip, sediment evacuation, and continued vertical pool floor incision in natural streams. Undercutting of the upstream pool wall was absent, and our results suggest that vertical drilling of successive plunge pools is a more efficient waterfall retreat mechanism than the classic model of headwall undercutting and collapse in homogeneous rock.

Our measurements of ion size distributions near a waterfall provided new evidence for a waterfall-induced modification of air ion sizes. The ion size spectrum near a waterfall permanently differs from that in ordinary tropospheric air. In this paper we investigated the near-waterfall air ions chemical nature in detail. We carried out a simulation series of air small negative ion evolution, proposing that falling water, as a new environmental component, increases the concentration of OH{sup -} cluster ions. The produced OH{sup -} ions were employed as an extra input for our ion evolution model. The presence of additional OH{sup -} ions resulted in a decrease of typically model-provided NO{sub 3}{sup -} and/or HSO{sub 4}{sup -} cluster ion concentrations and an increase of the abundance of HCO{sub 3}{sup -} cluster ions. Near the waterfall the latter ions became dominant in our simulations. (orig.)

Hybrid inflation along waterfall trajectories

International Nuclear Information System (INIS)

Clesse, Sebastien

2011-01-01

We identify a new inflationary regime for which more than 60 e-folds are generated classically during the waterfall phase occurring after the usual hybrid inflation. By performing a Bayesian Monte-Carlo-Markov-Chain analysis, this scenario is shown to take place in a large part of the parameter space of the model. When this occurs, the observable perturbation modes leave the Hubble radius during waterfall inflation. The power spectrum of adiabatic perturbations is red, possibly in agreement with CMB constraints. Particular attention has been given to study only the regions for which quantum backreactions do not affect the classical dynamics. Implications concerning the preheating and the absence of topological defects in our Universe are discussed.

The Fast Flux Test Facility (FFTF) is a 400 Mwt sodium-cooled fast reactor operating at the Hanford Engineering Development Laboratory, Richland, Washington, to conduct fuels and materials testing in support of the US Liquid Metal Fast Breeder Reactor (LMFBR) program. Startup and initial power testing included a comprehensive series of nonnuclear and nuclear tests to verify the thermal, hydraulic, and neutronic characteristics of the plant. A specially designed series of natural circulation tests were then performed to demonstrate the inherent safety features of the plant. Early in 1982, the FFTF began its first 100-day irradiation cycle. Since that time the plant has operated very well, achieving a cycle capacity factor of 94% in the most recent irradiation cycle. Seventy-five specific test assemblies and 25,000 individual fuel pins have been irradiated, some in excess of 80 MWd/Kg

The role of waterfalls in controlling the style and pace of landscape adjustment

Science.gov (United States)

DiBiase, R.; Lamb, M. P.; Whipple, K. X.

2013-12-01

Bedrock rivers set the pace of landscape adjustment to tectonic or climatic forcing by transmitting signals of baselevel change upstream through the channel network and ultimately to hillslopes. River incision is typically modeled as a monotonic function of bed shear stress, modulated by sediment tools and cover effects, but these models break down in landscapes where waterfalls are common due to changes in flow dynamics across steep, near-vertical reaches. Here we investigate how waterfalls influence the response times of landscapes to external forcing with a conceptual long-profile model and field observations from the San Gabriel Mountains, California. We show that the transient channel response of rivers with waterfalls can either be 'slow' or 'fast' relative to the response of rivers without waterfalls, and identify a series of field tests to identify which end-member behavior is present for natural waterfalls. We apply this conceptual model to the 300 km2 watershed of Big Tujunga Creek in the San Gabriel Mountains, where we identified over 800 bedrock steps greater than 3m in height from a 1m LiDAR DEM and 20 km of detailed field surveys. Two prominent slope-break knickpoints along the mainstem characterized by numerous waterfalls show contrasting behavior. For the upper knickpoint, waterfalls align with bands of harder rock exposed on adjacent hillslopes, and between waterfalls the channel is mantled by large (>2 m) boulders, suggesting that waterfalls here are stalled and enhance the preservation of an upstream relict landscape. In contrast, the lower knickpoint is characterized by waterfalls within an incised inner gorge, and the intervening reaches are a mixture of gravel and exposed bedrock. These observations, combined with a well-preserved strath terrace level parallel with the modern channel downstream of the inner gorge, indicate that the waterfalls here are retreating rapidly relative to background river incision. Our results highlight the

Controls on Filling and Evacuation of Sediment in Waterfall Plunge Pools

Science.gov (United States)

Scheingross, J. S.; Lamb, M. P.

2014-12-01

Many waterfalls are characterized by the presence of deep plunge pools that experience periods of sediment fill and evacuation. These cycles of sediment fill are a first order control on the relative magnitude of lateral versus vertical erosion at the base of waterfalls, as vertical incision requires cover-free plunge pools to expose the bedrock floor, while lateral erosion can occur when pools are partially filled and plunge-pool walls are exposed. Currently, there exists no mechanistic model describing sediment transport through waterfall plunge pools, limiting our ability to predict waterfall retreat. To address this knowledge gap, we performed detailed laboratory experiments measuring plunge-pool sediment transport capacity (Qsc_pool) under varying waterfall and plunge-pool geometries, flow hydraulics, and sediment size. Our experimental plunge-pool sediment transport capacity measurements match well with a mechanistic model we developed which combines existing waterfall jet theory with a modified Rouse profile to predict sediment transport capacity as a function of water discharge and suspended sediment concentration at the plunge-pool lip. Comparing the transport capacity of plunge pools to lower gradient portions of rivers (Qsc_river) shows that, for transport limited conditions, plunge pools fill with sediment under modest water discharges when Qsc_river > Qsc_pool, and empty to bedrock under high discharges when Qsc_pool > Qsc_river. These results are consistent with field observations of sand-filled plunge pools with downstream boulder rims, implying filling and excavation of plunge pools over single-storm timescales. Thus, partial filling of waterfall plunge pools may provide a mechanism to promote lateral undercutting and retreat of waterfalls in homogeneous rock in which plunge-pool vertical incision occurs during brief large floods that expose bedrock, whereas lateral erosion may prevail during smaller events.

Sediment transport through self-adjusting, bedrock-walled waterfall plunge pools

Science.gov (United States)

Scheingross, Joel S.; Lamb, Michael P.

2016-05-01

Many waterfalls have deep plunge pools that are often partially or fully filled with sediment. Sediment fill may control plunge-pool bedrock erosion rates, partially determine habitat availability for aquatic organisms, and affect sediment routing and debris flow initiation. Currently, there exists no mechanistic model to describe sediment transport through waterfall plunge pools. Here we develop an analytical model to predict steady-state plunge-pool depth and sediment-transport capacity by combining existing jet theory with sediment transport mechanics. Our model predicts plunge-pool sediment-transport capacity increases with increasing river discharge, flow velocity, and waterfall drop height and decreases with increasing plunge-pool depth, radius, and grain size. We tested the model using flume experiments under varying waterfall and plunge-pool geometries, flow hydraulics, and sediment size. The model and experiments show that through morphodynamic feedbacks, plunge pools aggrade to reach shallower equilibrium pool depths in response to increases in imposed sediment supply. Our theory for steady-state pool depth matches the experiments with an R2 value of 0.8, with discrepancies likely due to model simplifications of the hydraulics and sediment transport. Analysis of 75 waterfalls suggests that the water depths in natural plunge pools are strongly influenced by upstream sediment supply, and our model provides a mass-conserving framework to predict sediment and water storage in waterfall plunge pools for sediment routing, habitat assessment, and bedrock erosion modeling.

Delaying the waterfall transition in warm hybrid inflation

We analyze the dynamics and observational predictions of supersymmetric hybrid inflation in the warm regime, where dissipative effects are mediated by the waterfall fields and their subsequent decay into light degrees of freedom. This produces a quasi-thermal radiation bath with a slowly-varying temperature during inflation and further damps the inflaton's motion, thus prolonging inflation. As in the standard supercooled scenario, inflation ends when the waterfall fields become tachyonic and ...

Decontamination and decommissioning of the extraction chemical room at the West Valley Demonstration Project. Final topical report, December 1982-April 1984

Phillips, E.C.

1985-12-01

The purpose of this report is to describe the preparation of a facility for use in decontaminating and decommissioning (D and D) extraction cells at the West Valley Demonstration Project (WVDP). In order to prepare such a facility, it was necessary to decontaminate, decommission and equip the Extraction Chemical Room (XCR) at the WVDP. This report describes the D and D of the XCR from a radioactively contaminated condition to an essentially shirt sleeve environment. Also included is a description of the changes made to the XCR for use in the D and D of the extraction cells which are located beneath the floor of the XCR. In the XCR prior to D and D, radiological surveys indicated a maximum radiation field of 5 mrad/hr, due to sources internal to the room, and 20,000 dpm beta/100 cm 2 surface contamination. A radiation source external to the XCR caused a hot spot with a 9 mrad/hr exposure rate inside the XCR. The D and D of the XCR, located on the fifth floor elevation 48.8 m of the reprocessing plant at the WVDP, has been completed. D and D operations included removal of piping, tanks, supports, and equipment to provide a clean work area of about 278.7 m 2 and 5.2 m high. Subsequent to the removal of piping and equipment, a new floor was installed in part of the room and equipment for use in the D and D of the extraction cells was added. The equipment included a large containment tent over the extraction cell hatches, a jib crane, two gantries, a monorail crane, an air transporter, and a temporary ventilation system. D and D operations in the XCR were initiated in December 1982 and the completed facility was available for use in February 1984

Nucleation of Waterfalls at Fault Scarps Temporarily Shielded By Alluvial Fan Aggradation.

Science.gov (United States)

Malatesta, L. C.; Lamb, M. P.

2014-12-01

Waterfalls are important components of mountain river systems and they can serve as an agent to transfer tectonic, climatic, or authigenic signals upstream through a catchment. Retreating waterfalls lower the local base level of the adjacent hillslopes, and temporarily increase sediment delivery to the fluvial system. Their creation is often attributed to seismic ruptures, lithological boundaries, or the coalescence of multiple smaller steps. We explore here a mechanism for the nucleation of waterfalls that does not rely on sudden seismic slip but on the build-up of accumulated slip during periods of fault burial by fluvial aggradation. Alluvial fans are common features at the front of mountain ranges bound by normal or thrust faults. Climate change or internal forcing in the mountain catchment modifies the equilibrium slope of alluvial fans. When alluvial fans aggrade, they shield the active fault scarp from fluvial erosion allowing the scarp to grow undisturbed. The scarp may then be exposed when the channel incises into the fan exposing a new bedrock waterfall. We explore this mechanism analytically and using a numerical model for bedrock river incision and sediment deposition. We find that the creation of waterfalls by scarp burial is limited by three distinct timescales: 1) the critical timescale for the scarp to grow to the burial height, 2) the timescale of alluvial re-grading of the fan, and 3) the timescale of the external or internal forcing, such as climate change. The height of the waterfall is controlled by i) the difference in equilibrium alluvial-fan slopes, ii) the ratio of the respective fan and catchment sizes, iii) the catchment wide denudation rate, and iv) the fault slip rate. We test whether an individual waterfall could be produced by alluvial shielding of a scarp, and identify the tectonic, climatic, or authigenic nature of waterfalls using example field sites in the southwest United States.

No large scale curvature perturbations during the waterfall phase transition of hybrid inflation

Abolhasani, Ali Akbar; Firouzjahi, Hassan

2011-01-01

In this paper the possibility of generating large scale curvature perturbations induced from the entropic perturbations during the waterfall phase transition of the standard hybrid inflation model is studied. We show that whether or not appreciable amounts of large scale curvature perturbations are produced during the waterfall phase transition depends crucially on the competition between the classical and the quantum mechanical backreactions to terminate inflation. If one considers only the classical evolution of the system, we show that the highly blue-tilted entropy perturbations induce highly blue-tilted large scale curvature perturbations during the waterfall phase transition which dominate over the original adiabatic curvature perturbations. However, we show that the quantum backreactions of the waterfall field inhomogeneities produced during the phase transition dominate completely over the classical backreactions. The cumulative quantum backreactions of very small scale tachyonic modes terminate inflation very efficiently and shut off the curvature perturbation evolution during the waterfall phase transition. This indicates that the standard hybrid inflation model is safe under large scale curvature perturbations during the waterfall phase transition.

This dissertation examines the American nuclear theatre - works that directly explore nuclear technology (weapons and energy). Background chapters describe the history of nuclear development, discourse, and strategy; the response of the arts; and the history of the American nuclear theatre, which began in 1946 and burgeoned after 1980. Five recent, representative productions - four stage dramas and one nonviolent symbolic action - are examined as theatrical strategies: Dead End Kids: a History of Nuclear Power (1980), by JoAnne Akalaitis/Mabour Mines; the Story of One Who Set Out to Study Fear (1981), by Peter Schumann/Bread and Puppet Theater; Factwino vs. Armageddonman (1982), by the San Francisco Mime Troupe ; Ashes, Ashes, We All Fall Down (1982), by Martha Beosing/At the Foot of the Mountain; and the Plowshares 8 events (1980-1984). All five productions were created collaboratively. All assaulted the boundaries between art and life. All were dialectical and tried to create a fundamental shift in consciousness about nuclear weapons. All suggested that the nuclear age is a new historical situation: war and business are interconnected with a new technology which makes possible the end of the world. Three productions employed historical images of mass death to provide emotional and moral comparisons. All finally called for each audience member to take responsibility for the current nuclear situation

Full Text Available Waterfalls gives the impression of a lifeless zone because researchers have historically focused on the hydrology, ecotourism and geological features. Effective management will require an understanding of changes in species composition and distribution of macro-biota. Monthly samples were taken in wet and dry seasons, over two year period in three regions along the 6817.7 m length of the Agbokum waterfalls. Macro-biota exhibited distinct pattern in respect of seasonal and spatial changes. Trachelomonas volzii, the most abundant phytoplankton species reduced from 686 in the dry season to 143 in the wet, and from 455 downstream to 91, midstream (waterfalls region. Zooplankton species Calanus finmarchicus decreased from 511 during dry season to 36 in the wet and from 334 downstream to 7, midstream. 71.7 percent of the total macro-invertebrates were recorded from downstream reaches while only 6.3 percent were contributed by midstream. Percentage cover of marginal vegetation by Bambusasp, Symphonia and Elaeis guineesis displayed progressive increase from upstream reaching a maximum of 38.5 mean percent cover in the relatively undisturbed downstream. In contrast, Raphia vinifera, Havea brasiliensis, Grewia sp. and Cocos nucifera shrank in size from 34% to 8% at the midstream stretches of the river while only nymphia- rich vegetation becomes more frequent in the middle reaches. The disturbance regimes of the midstream reaches of Agbokum waterfalls combined with its very low faunal and floral diversity has made the environment unstable therefore susceptible to the invasion of disturbance tolerant biota.

Flow through collapsible tubes at low Reynolds numbers. Applicability of the waterfall model.

Lyon, C K; Scott, J B; Wang, C Y

1980-07-01

The applicability of the waterfall model was tested using the Starling resistor and different viscosities of fluids to vary the Reynolds number. The waterfall model proved adequate to describe flow in the Starling resistor model only at very low Reynolds numbers (Reynolds number less than 1). Blood flow characterized by such low Reynolds numbers occurs only in the microvasculature. Thus, it is inappropriate to apply the waterfall model indiscriminately to flow through large collapsible veins.

Landscape is one of the valuable assets in tourism, especially in rural tourism. Good landscape planning can be increasing the tourism in one place. In Geopark area, landscape planning is also necessary, and it is because geopark area is also a landscape. This paper aims to create a landscape planning concept in Sipiso-Piso Waterfall that can be used to improve the tourism in Sipiso-piso Waterfall. The method that used in this paper is a qualitative method that is used interviews with related stakeholders like, local figure, government, and academic, and field observation in the study area. The data obtained would be analyzed with four elements of landscape namely, open space, pedestrian path, street circulation, and street furniture. The result shows that the four elements of landscape in Sipiso-Piso Waterfall is still not proper and needs improvement.

Operational short-term Probabilistic Volcanic Hazard Assessment of tephra fallout: an example from the 1982-1984 unrest at Campi Flegrei

Probabilistic Volcanic Hazard Assessment (PVHA) represents the most complete scientific contribution for planning rational strategies aimed at mitigating the risk posed by volcanic activity at different time scales. The definition of the space-time window for PVHA is related to the kind of risk mitigation actions that are under consideration. Short intervals (days to weeks) are important for short-term risk mitigation actions like the evacuation of a volcanic area. During volcanic unrest episodes or eruptions, it is of primary importance to produce short-term tephra fallout forecast, and frequently update it to account for the rapidly evolving situation. This information is obviously crucial for crisis management, since tephra may heavily affect building stability, public health, transportations and evacuation routes (airports, trains, road traffic) and lifelines (electric power supply). In this study, we propose a methodology for the short-term PVHA and its operational implementation, based on the model BET_EF, in which measures from the monitoring system are used to routinely update the forecast of some parameters related to the eruption dynamics, that is, the probabilities of eruption, of every possible vent position and every possible eruption size. Then, considering all possible vent positions and eruptive sizes, tephra dispersal models are coupled with frequently updated meteorological forecasts. Finally, these results are merged through a Bayesian procedure, accounting for epistemic uncertainties at all the considered steps. As case study we retrospectively study some stages of the volcanic unrest that took place in Campi Flegrei (CF) in 1982-1984. In particular, we aim at presenting a practical example of possible operational tephra fall PVHA on a daily basis, in the surroundings of CF at different stages of the 1982-84 unrest. Tephra dispersal is simulated using the analytical HAZMAP code. We consider three possible eruptive sizes (a low, a medium and a

In particular, it may lead to excessive black hole formation. We here consider standard hybrid inflation, where the tachyonic mass of the waterfall field is much bigger than the Hubble parameter.

We carried out numerical calculations of a contribution of the waterfall field to the primordial curvature perturbation (on uniform density hypersurfaces) ζ, which is produced during waterfall transition in hybrid inflation scenario. The calculation is performed for a broad interval of values of the model parameters. We show that there is a strong growth of amplitudes of the curvature perturbation spectrum in the limit when the bare mass-squared of the waterfall field becomes comparable with the square of Hubble parameter. We show that in this limit the primordial black hole constraints on the curvature perturbations must be taken into account. It is shown that, in the same limit, peak values of the curvature perturbation spectra are far beyond horizon, and the spectra are strongly non-Gaussian.

We carried out numerical calculations of a contribution of the waterfall field to the primordial curvature perturbation (on uniform density hypersurfaces) ζ, which is produced during waterfall transition in hybrid inflation scenario. The calculation is performed for a broad interval of values of the model parameters. We show that there is a strong growth of amplitudes of the curvature perturbation spectrum in the limit when the bare mass-squared of the waterfall field becomes comparable with the square of Hubble parameter. We show that in this limit the primordial black hole constraints on the curvature perturbations must be taken into account. It is shown that, in the same limit, peak values of the curvature perturbation spectra are far beyond horizon, and the spectra are strongly non-Gaussian

We study carefully the contribution of the waterfall field to the curvature perturbation at the end of hybrid inflation. In particular we clarify the parameter dependence analytically under reasonable assumptions on the model parameters. After calculating the mode function of the waterfall field, we use the δN formalism and confirm the previously obtained result that the power spectrum is very blue with the index 4 and is absolutely negligible on large scales. However, we also find that the resulting curvature perturbation is highly non-Gaussian and hence we calculate the bispectrum. We find that the bispectrum is at leading order independent of momentum and exhibits its peak at the equilateral limit, though it is unobservably small on large scales. We also present the one-point probability distribution function of the curvature perturbation

The concept of the waterfall phenomenon in Zone 2 in the pulmonary vasculature is well known from West's lung model. It is believed that the flow through this zone is determined by the pressure difference between the pulmonary artery and alveoli, and the left atrial pressure is not transmissible to the alveolar capillaries. However, it is impossible to see whether alveolar capillaries are really displaying the waterfall phenomenon or not. In this review, the interrelation between the flow and geometry of the alveolar capillaries in the waterfall phenomenon is analyzed based on physiological studies using a model system and isolated lung lobe experiments. Further, extending the concept to the analysis of ventilatory changes of the inferior vena cava (IVC) configuration, it is ascertained that the waterfall phenomenon normally occurs in the IVC during inspiration just before it enters the thorax and the waterfall phenomenon in the IVC disintegrates with elevation of the central venous pressure. Because these configurations of the IVC in normal and abnormal conditions are visible with ultrasonography, the technique is very useful as a noninvasive approach to diagnose right heart failure.

Development of Waterfall Cliff Face: An Implication from Multitemporal High-definition Topographic Data

Bedrock knickpoints (waterfalls) often act as erosional front in bedrock rivers, whose geomorphological processes are various. In waterfalls with vertical cliffs, both fluvial erosion and mass movement are feasible to form the landscape. Although morphological changes of such steep cliffs are sometimes visually observed, quantitative and precise measurements of their spatiotemporal distribution have been limited due to poor accessibility to such cliffs. For the clarification of geomorphological processes in such cliffs, multi-temporal mapping of the cliff face at a high resolution can be advantaged by short-range remote sensing approaches. Here we carry out multi-temporal terrestrial laser scanning (TLS), as well as structure-from-motion multi-view stereo (SfM-MVS) photogrammetry based on unmanned aerial system (UAS) for accurate topographic mapping of cliffs around a waterfall. The study site is Kegon Falls in central Japan, having a vertical drop of surface water from top of its overhanging cliff and groundwater outflows from its lower portions. The bedrock consists of alternate layers of jointed andesite lava and conglomerates. The latest major rockfall in 1986 caused approximately 8-m recession of the waterfall lip. Three-dimensional changes of the rock surface were detected by multi-temporal measurements by TLS over years, showing the portions of small rockfalls and surface lowering in the bedrock. Erosion was frequently observed in relatively weak the conglomerates layer, whereas small rockfalls were often found in the andesite layers. Wider areas of the waterfall and cliff were also measured by UAS-based SfM-MVS photogrammetry, improving the mapping quality of the cliff morphology. Point clouds are also projected on a vertical plane to generate a digital elevation model (DEM), and cross-sectional profiles extracted from the DEM indicate the presence of a distinct, 5-10-m deep depression in the cliff face. This appears to have been formed by freeze-thaw and

Rockfalls in cliffs surrounding waterfall revealed by high-definition topographic measurements

Bedrock rivers of volcanic terrain often comprise numerous knickpoints. Erosion of bedrock at knickpoints is an essential process of fluvial dissection of volcanic landforms, which also affects the deformations of surrounding slopes. However, short term (less than decadal) changes in bedrock landforms have often been limited to examine in a spatiotemporal framework. Here we use terrestrial laser scanning and SfM-MVS photogrammetry to detect recent annual changes in the morphology of cliffs surrounding a waterfall (Kegon Falls) on jointed andesite lava and conglomerates. The amount of bedrock deformation caused by small rockfalls and surface lowering are assessed in volume, which often appears in a relatively lower portion of the cliff. Such the changes are supposed to be affected by the enhanced supply of water and weathering following the latest major rockfall in 1986 which caused 8-m recession of the waterfall lip. The three-dimensional point cloud data is also utilized to construct a 3D model using cardboards, which is useful for understanding the topography and its changes of the waterfall as educational resources.

Large-scale perturbations from the waterfall field in hybrid inflation

Fonseca, José; Wands, David; Sasaki, Misao

2010-01-01

We estimate large-scale curvature perturbations from isocurvature fluctuations in the waterfall field during hybrid inflation, in addition to the usual inflaton field perturbations. The tachyonic instability at the end of inflation leads to an explosive growth of super-Hubble scale perturbations, but they retain the steep blue spectrum characteristic of vacuum fluctuations in a massive field during inflation. The power spectrum thus peaks around the Hubble-horizon scale at the end of inflation. We extend the usual δN formalism to include the essential role of these small fluctuations when estimating the large-scale curvature perturbation. The resulting curvature perturbation due to fluctuations in the waterfall field is second-order and the spectrum is expected to be of order 10 −54 on cosmological scales

The Robust Software Feedback Model: An Effective Waterfall Model Tailoring for Space SW

The selection of the most suitable software life cycle process is of paramount importance in any space SW project. Despite being the preferred choice, the waterfall model is often exposed to some criticism. As matter of fact, its main assumption of moving to a phase only when the preceding one is completed and perfected (and under the demanding SW schedule constraints) is not easily attainable. In this paper, a tailoring of the software waterfall model (named “Robust Software Feedback Model”) is presented. The proposed methodology sorts out these issues by combining a SW waterfall model with a SW prototyping approach. The former is aligned with the SW main production line and is based on the full ECSS-E-ST-40C life-cycle reviews, whereas the latter is carried out in advance versus the main SW streamline (so as to inject its lessons learnt into the main streamline) and is based on a lightweight approach.

Hydrogen sulfide (H 2 S) represents one of the main odorant gases emitted from sewer networks. A mathematical model can be a fast and low-cost tool for estimating its emission. This study investigates two approaches to modeling H 2 S gas transfer at a waterfall in a discharge manhole. The first approach is based on an adaptation of oxygen models for H 2 S emission at a waterfall and the second consists of a new model. An experimental set-up and a statistical data analysis allowed the main factors affecting H 2 S emission to be studied. A new model of the emission kinetics was developed using linear regression and taking into account H 2 S liquid concentration, waterfall height and fluid velocity at the outlet pipe of a rising main. Its prediction interval was estimated by the residual standard deviation (15.6%) up to a rate of 2.3 g H 2 S·h -1 . Finally, data coming from four sampling campaigns on sewer networks were used to perform simulations and compare predictions of all developed models.

2003-09-05

We have undertaken an inelastic neutron scattering study of the perovskite relaxor ferroelectric Pb(Zn(1/3)Nb(2/3))O3 with 8% PbTiO3 (PZN-8%PT) in order to elucidate the origin of the previously reported unusual kink on the low frequency transverse phonon dispersion curve (known as the "waterfall effect"). We show that its position (q(wf)) depends on the choice of the Brillouin zone and that the relation of q(wf) to the size of the polar nanoregions is highly improbable. The waterfall phenomenon is explained in the framework of a simple model of coupled damped harmonic oscillators representing the acoustic and optic phonon branches.

A density spike on astrophysical scales from an N-field waterfall transition

Hybrid inflation models are especially interesting as they lead to a spike in the density power spectrum on small scales, compared to the CMB, while also satisfying current bounds on tensor modes. Here we study hybrid inflation with N waterfall fields sharing a global SO (N) symmetry. The inclusion of many waterfall fields has the obvious advantage of avoiding topologically stable defects for N > 3. We find that it also has another advantage: it is easier to engineer models that can simultaneously (i) be compatible with constraints on the primordial spectral index, which tends to otherwise disfavor hybrid models, and (ii) produce a spike on astrophysically large length scales. The latter may have significant consequences, possibly seeding the formation of astrophysically large black holes. We calculate correlation functions of the time-delay, a measure of density perturbations, produced by the waterfall fields, as a convergent power series in both 1 / N and the field's correlation function Δ (x). We show that for large N, the two-point function is ∝Δ2 (| x |) / N and the three-point function is ∝ Δ (| x - y |) Δ (| x |) Δ (| y |) /N2. In accordance with the central limit theorem, the density perturbations on the scale of the spike are Gaussian for large N and non-Gaussian for small N.

This is a report of the results of gastric mass survey performed during a 3-year period from 1982 through 1984. Included in this survey were 16,781 A-bomb survivors. The subjects were divided into three groups: a group exposed at less than or equal to 2,000 m from ground zero (Group 1), a group exposed at > 2,000 m from ground zero (Group 2), and a group consisting of those who entered the city after the bombing or others (Group 3). Regarding the rate for necessity of detailed examinations, there was no difference among the groups. The incidence of abnormal findings was 6.1% in Group 1, 5.4% in Group 2, and 4.9% in Group 3, showing significant difference between Groups 1 and 3. Similarly, the incidence of respective disease was significantly higher in Group 1 than Group 3: gastritis was the most common (2.7% vs 2.0%), followed by gastric polyp (0.9% vs 0.5%) and gastric cancer (0.6% vs 0.2%). The age-adjusted incidence of gastric cancer and polyp was high, irrespective of sex, in Group 1. This was significant for gastric cancer in women and for gastric polyp in men. The incidence of gastric cancer in any age class was higher in Group 1 than Group 3. The incidence of gastric polyp tended to increase with aging in Group 1, being higher particularly for survivors over the age of 50 than those in Groups 2 and 3. (Namekawa, K.).

The hybrid inflation waterfall and the primordial curvature perturbation

International Nuclear Information System (INIS)

Lyth, David H.

2012-01-01

Without demanding a specific form for the inflaton potential, we obtain an estimate of the contribution to the curvature perturbation generated during the linear era of the hybrid inflation waterfall. The spectrum of this contribution peaks at some wavenumber k = k * , and goes like k 3 for k * , making it typically negligible on cosmological scales. The scale k * can be outside the horizon at the end of inflation, in which case ζ = −(g 2 −(g 2 )) with g gaussian. Taking this into account, the cosmological bound on the abundance of black holes is likely to be satisfied if the curvaton mass m much bigger than the Hubble parameter H, but is likely to be violated if m∼< H. Coming to the contribution to ζ from the rest of the waterfall, we are led to consider the use of the 'end-of-inflation' formula, giving the contribution to ζ generated during a sufficiently sharp transition from nearly-exponential inflation to non-inflation, and we state for the first time the criterion for the transition to be sufficiently sharp. Our formulas are applied to supersymmetric GUT inflation and to supernatural/running-mass inflation

Influence of waterfall aeration and seasonal temperature variation on the iron and arsenic attenuation rates in an acid mine drainage system

2012-01-01

Dramatic seasonal changes in water chemistry and precipitate mineralogy associated with acid-mine drainage (AMD) in the waterfall and creek sections of the Chinkuashih area, northern Taiwan were investigated. Special attention has been paid to the kinetic effects of seasonal temperature variation and waterfall aeration. Precipitation of schwertmannite associated with removal of metals and As are indicated by delicate growth microstructures on precipitate surfaces, X-ray diffraction data, and downstream reductions of metal and As concentrations. Geochemical modeling suggested a downstream increase of the degree of saturation/supersaturation with respect to schwertmannite in the waterfall section, which can be attributed to high Fe 2+ oxidation rates. The waterfall section was characterized by high rates and model rate constants of Fe 2+ oxidation (6.1–6.7 × 10 −6 mol L −1 s −1 and 2.7–2.9 × 10 −2 s −1 ) and Fe (schwertmannite) precipitation (1.7–2.1 × 10 −6 mol L −1 s −1 and 3.5–4.1 × 10 −7 mol L −1 s −1 ). A high As sorption rate (4.7–6.3 × 10 −9 mol L −1 s −1 ) and low As distribution coefficient (7.9–11.8 × 10 −9 mol −1 L) were observed. The creek section showed up to 1–2 orders of magnitude slower rates and lower rate constants than the waterfall section and had seasonal variations comparable to those in areas polluted by AMD elsewhere. The summer rates were 4–5 times higher than the winter rates in the creek section, and are largely attributed to a temperature effect. In contrast, the seasonal differences in rate and rate constant were small in the waterfall section. Several factors associated with the waterfall aeration in addition to elevated temperature and As concentration enhanced Fe and As attenuation in the waterfall section. The waterfall effects on Fe precipitation rate were enhanced when the flow rate was large in the winter. Despite the remarkable removal of metals and As by the rapid

Inhibition of coronary blood flow by a vascular waterfall mechanism.

The mechanism whereby systole inhibits coronary blood flow was examined. A branch of the left coronary artery was maximally dilated with an adenosine infusion, and the pressure-flow relationship was obtained for beating and arrested states. The pressure-flow curve for the arrested state was shifted toward higher pressures and in the range of pressures above peak ventricular pressure was linear and parallel to that for the arrested state. Below this range the curve for the beating state converged toward that for the arrested state and was convex to the pressure axis. These results were compared with a model of the coronary vasculature that consisted of numerous parallel channels, each responding to local intramyocardial pressure by forming vascular waterfalls. When intramyocardial pressure in the model was assigned values from zero at the epicardium to peak ventricular pressure at the endocardium, pressure-flow curves similar to the experimental ones resulted. Thus, we conclude that systole inhibits coronary perfusion by the formation of vascular waterfalls and that the intramyocardial pressures responsible for this inhibition do not significantly exceed peak ventricular pressure.

This paper describes the extension of the waterfall model using MVC architectural pattern for software development. The waterfall model is the based model of the most widely used in software development, yet there are still many problems in it. The general issue usually happens on data changes that cause the delays on the process itself. On the other hand, the security factor on the software as well as one of the major problems. This study uses PHP programming language for implementation. Although this model can be implemented in several programming languages with the same concept. This study is based on MVC architecture so that it can improve the performance of both software development and maintenance, especially concerning security, validation, database access, and routing.

Uncertainties regarding the feasibility of using an annular waterfall of liquid lithium to protect the first wall in inertial confinement fusion (ICF) reactor cavities have prompted a theoretical investigation of annular jet stability. Infinitesimal perturbation techniques are applied to an idealized model of the jet with disturbances acting upon either or both of the free surfaces. Dispersion relations are derived which predict the range of disturbance frequencies leading to instability, as well as the perturbation growth rates and jet breakup length. The results are extended to turbulent annular jets and are evaluated for the lithium waterfall design. It is concluded that inherent instabilities due to turbulent fluctuations will not cause the jet to break up over distances comparable to the height of the reactor cavity

Above all, relevant measures for soil remediation are put forward.

Die boek Job as bron van intertekste vir ‘Wie weet?' (Die waarheid gelieg, 1984

Full Text Available The Book of Job as a source of intertexts for T.T. Cloete’s short story ‘Wie weet?’ (Die waarheid gelieg, 1984 T.T. Cloete’s account of a woman's physical and spiritual agony in the short story “Wie weet?” ffrom Die waarheid gelieg, 1984, read within the South African/Afrikaans cultural context, presents several indicators that the Book of Job is its intertext, the most explicit pointer being the role of the sufferer’s sister-in-law. Intertextuality in Cloete’s oeuvre often takes the form of a creative reworking or rereading of texts (cf Scholtz, 1984; Botha, 1984; Roos, 1986. Roos comments on the caricatural treatment of theme in Cloete’s “Veg om te verloor” (Cloete, 1984, highlighted by the rereading imposed on the reader of Van Melle’s well-known story "Die joiner”, creating distrust in the implicit author of the Cloete text. The argument in this essay is that the explicit engagement of the intertext, as in "Wie weet?”, also serves as an affirmative complement to the negative incompleteness of the rereading. Thus the desperate questioning of "Wie weet?” becomes an integral part of a reading of Cloete’s oeuvre as a hymn to God’s omnipotence and mercy, epitomized in the poem "Van Horn en my” (Jukstaposisie, 1982.

Waterfall notch-filtering for restoration of acoustic backscatter records from Admiralty Bay, Antarctica

Science.gov (United States)

Fonseca, Luciano; Hung, Edson Mintsu; Neto, Arthur Ayres; Magrani, Fábio José Guedes

2018-06-01

A series of multibeam sonar surveys were conducted from 2009 to 2013 around Admiralty Bay, Shetland Islands, Antarctica. These surveys provided a detailed bathymetric model that helped understand and characterize the bottom geology of this remote area. Unfortunately, the acoustic backscatter records registered during these bathymetric surveys were heavily contaminated with noise and motion artifacts. These artifacts persisted in the backscatter records despite the fact that the proper acquisition geometry and the necessary offsets and delays were applied during the survey and in post-processing. These noisy backscatter records were very difficult to interpret and to correlate with gravity-core samples acquired in the same area. In order to address this issue, a directional notch-filter was applied to the backscatter waterfall in the along-track direction. The proposed filter provided better estimates for the backscatter strength of each sample by considerably reducing residual motion artifacts. The restoration of individual samples was possible since the waterfall frame of reference preserves the acquisition geometry. Then, a remote seafloor characterization procedure based on an acoustic model inversion was applied to the restored backscatter samples, generating remote estimates of acoustic impedance. These remote estimates were compared to Multi Sensor Core Logger measurements of acoustic impedance obtained from gravity core samples. The remote estimates and the Core Logger measurements of acoustic impedance were comparable when the shallow seafloor was homogeneous. The proposed waterfall notch-filtering approach can be applied to any sonar record, provided that we know the system ping-rate and sampling frequency.

Detection of morphological changes in cliff face surrounding a waterfall using terrestrial laser scanning and unmanned aerial system

Science.gov (United States)

Hayakawa, Yuichi S.; Obanawa, Hiroyuki

2015-04-01

Waterfall or bedrock knickpoint appears as an erosional front in bedrock rivers forming deep v-shaped valley downstream. Following the rapid fluvial erosion of waterfall, rockfalls and gravita-tional collapses often occur in surrounding steep cliffs. Although morphological changes of such steep cliffs are sometimes visually observed, quantitative and precise measurements of their spatio-temporal distribution have been limited due to the difficulties in direct access to such cliffs if with classical measurement methods. However, for the clarification of geomorphological processes oc-curring in the cliffs, multi-temporal mapping of the cliff face at a high resolution is necessary. Re-mote sensing approaches are therefore suitable for the topographic measurements and detection of changes in such inaccessible cliffs. To achieve accurate topographic mapping of cliffs around a wa-terfall, here we perform multi-temporal terrestrial laser scanning (TLS), as well as structure-from-motion multi-view stereo (SfM-MVS) photogrammetry based on unmanned aerial system (UAS). The study site is Kegon Falls in central Japan, having a vertical drop of surface water from top of its overhanging cliff, as well as groundwater outflows from its lower portions. The bedrock is composed of alternate layers of andesite lava and conglomerates. Minor rockfalls in the cliffs are often ob-served by local people. The latest major rockfall occurred in 1986, causing ca. 8-m upstream propa-gation of the waterfall lip. This provides a good opportunity to examine the changes in the surround-ing cliffs following the waterfall recession. Multi-time point clouds were obtained by TLS measure-ment over years, and the three-dimensional changes of the rock surface were detected, uncovering the locus of small rockfalls and gully developments. Erosion seems particularly frequent in relatively weak the conglomerates layer, whereas small rockfalls seems to have occurred in the andesite layers. Also, shadows in the

Serum from endangered San Joaquin kit foxes, Vulpes macrotis mutica, and sympatric wildlife inhabiting the Elk Hills Petroleum Reserve, Kern County, and Elkhorn Plain, San Luis Obispo County, California, was collected in 1981 to 1982 and 1984, and tested for antibodies against 10 infectious disease pathogens. Proportions of kit fox sera containing antibodies against diseases were: canine parvovirus, 100% in 1981 to 1982 and 67% in 1984; infectious canine hepatitis, 6% in 1981 to 1982 and 21% in 1984; canine distemper, 0 in 1981 to 1982 and 14% in 1984; tularemia, 8% in 1981 to 1982 and 31% in 1984; Brucella abortus, 8% in 1981 to 1982 and 3% in 1984; Brucella canis, 14% in 1981 to 1982 and 0 in 1984; toxoplasmosis, 6% in 1981 to 1982; coccidioidomycosis, 3% in 1981 to 1982; and plague and leptospirosis, 0 in 1981 to 1982. High population density, overlapping home ranges, ability to disperse great distances, and infestation by ectoparasites were cited as possible factors in the transmission and maintenance of these diseases in kit fox populations.

2017-02-01

Full Text Available A new target solution, the granular waterfall target, is proposed here for a muon collider or a muon-decay neutrino beam facility, especially for the moment which adopts a 15 MW continuous-wave (cw superconducting linac. Compared to the mercury jet target, the granular waterfall target works by a much simpler mechanism which can operate with a much more powerful beam, which are indicated by the detailed investigations into the heat depositions and the evaluations of the temperature increases for different target concepts. By varying proton beam kinetic energy and the geometrical parameters of the waterfall target, an overall understanding of the figure of merit concerning muon production for this target concept as the target solutions of the long-baseline neutrino factory and the medium-baseline moment is obtained. With 8 GeV beam energy and the optimal geometrical parameters, the influence on muon yield by adopting different beam-target interaction parameters is explored. Studies and discussions of the design details concerning beam dumping are also presented.

Steam generator tube performance: experience with water-cooled nuclear power reactors during 1983 and 1984

International Nuclear Information System (INIS)

Tatone, O.S.; Meindl, P.; Taylor, G.F.

1986-06-01

A review of the performance of steam generator tubes in water-cooled nuclear power reactors showed that tubes were plugged at 47 (35.6%) of the reactors in 1983 and at 63 (42.6%) of the reactors during 1984. In 1983 and 1984 3291 and 3335 tubes, respectively, were removed from service, about the same as in 1982. The leading causes assigned to tube failure were stress corrosion cracking from the primary side and stress corrosion cracking or intergranular attack from the secondary side. In addition 5668 tubes were repaired for further service by installation of internal sleeves. Most of these were believed to have deteriorated by one of the above mechanisms or by pitting. There is a continuing trend towards high-integrity condenser tube materials at sites cooled by brackish or sea water. 31 refs

Results of the CRCPD survey of 1984 low-level radioactive waste: progress to mid-September, 1986

The survey of 1984 low-level radioactive waste by the Conference of Radiation Control Program Directors, Inc., is the second such survey. The previous survey was for waste generated during 1982. The CRCPD survey of 1984 LLRW requested information concerning the license, the effluents and other on-site managed wastes, details of exported waste type, the capacity for storing waste prior to shipment and its average utilization during 1984. Details of the exported waste included waste type, processing and packaging, NRC class, burial site or broker to which the waste was sent, and anticipated waste generation by year and by class through 1989. Shortcomings of the questionnaire and preliminary results are discussed. Based on the results of the two surveys of low-level radioactive waste conducted by the CRCPD, and the serious discrepancies which exist between data on waste shipped by generators and that on waste received by disposal sites, the following recommendation is made. That a single, national repository be established for all data on the generation and ultimate disposition of low-level radioactive waste. 1 figure, 1 table

Radioactivity data are presented from Project Airstream (aircraft) for the year 1983 and for Project Ashcan (balloon) for the years 1982 and 1984. Due to budgetary constraints both Projects Airstream and Ashcan have been terminated. This will be the final report containing radioactivity data collected during projects airstream and ashcan. Included are gross gamma, gamma spectral and radiochemical analyses of filter samples. Quality control samples submitted along with the air filter samples were analyzed and the results are presented. Low activity on many of the filters precludes the estimation of the stratospheric inventories of /sup 239,240/Pu and 90 Sr. Based on data with count errors 90 Sr and /sup 239,240/Pu concentration for November 1983 was 0.2 +- 0.1 and 0.009 +- 0.006 Bq/1000 scm, respectively

Assessment of carbon dioxide sink/source in the oceanic areas: the results of 1982-84 investigation. Final technical report

Takahashi, T.; Chipman, D.W.; Smethie, W. Jr.; Goddard, J.; Trumbore, S.; Mathieu, G.G.; Sutherland, S.

1985-07-01

The oceanic CO 2 sink/source relationships over the tropical Atlantic Ocean, the eastern North and South Pacific Ocean, and the Ross Sea were investigated. The net CO 2 flux across the air-sea interface over these areas was estimated. Measurements of the Kr-85 in atmospheric samples collected over the central Pacific along the 155 0 W meridian were initiated. Based on the measurements of the difference between the pCO 2 values in the surface ocean water and the atmosphere and of the radon-222 distribution in the upper water column, we have found that the average net flux for the Atlantic equatorial belt, 10 0 N-10 0 S, is 1.3 moles CO 2 /m 2 .y out of the ocean, when our measurements were made in November 1982 through February 1983. The surface water pCO 2 data obtained over the eastern North and South Pacific during the period, October 1983 through January 1984, show that the equatorial zone between 2 0 N and 8 0 S is an intense CO 2 source area, whereas a 10 0 wide belt coinciding with the area between the Subtropical and Antarctic Convergence Zones is a strong CO 2 sink area. The temperate gyre area located north of about 5 0 N and that located between 8 0 S and 35 0 S are nearly in equilibrium with atmospheric CO 2 . The surface water pCO 2 data obtained in the Southern Ocean during the past ten or more years suggest strongly the existence of an intense CO 2 sink zone, the Circumpolar Low pCO 2 Zone, which is about 10 0 wide in latitude and centered at about 50 0 S surrounding the Antarctica Continent. The surface water of the Ross Sea is found to be a strong CO 2 sink during the period January 23 through February 12, 1984. Because of contamination problems, no reliable data for atmospheric krypton-85 have been obtained. 23 refs., 22 figs., 3 tabs

Full Text Available Given the growing recognition of the importance of the life course approach for the determination of chronic diseases, birth cohort studies are becoming increasingly important. This paper describes the methods used in the 1982 Pelotas (Brazil birth cohort study, one of the largest and longest studies of this type in developing countries. All 5,914 hospital births occurring in Pelotas in 1982 (over 99% of all deliveries were studied prospectively. The main stages of the study took place in 1983, 1984, 1986, 1995, 1997, 2000, and 2001. More than two thousand variables are available for each subject who participated in all stages of the study. Recent phases of the study included the examination of 2,250 males when presenting for the army recruitment exam in 2000, the study of a 27% sample of men and women in 2001 through household visits, and the study of over 400 children born to the cohort women. Follow-up rates in the recent stages of the cohort were 78.9% for the army examination and 69.0% for the household visits. Ethnographic and oral health studies were conducted in sub-samples. Some recent results on blood pressure, adolescent pregnancy, and asthma are presented as examples of utilization of the data. Suggestions on lessons learned for other cohort studies are proposed.Em função do reconhecimento crescente do enfoque do ciclo vital na determinação de doenças crônicas, estudos de coorte de nascimentos são cada vez mais importantes.

Morphological selection in an extreme flow environment: body shape and waterfall-climbing success in the Hawaiian stream fish Sicyopterus stimpsoni.

Flow characteristics are a prominent factor determining body shapes in aquatic organisms, and correlations between body shape and ambient flow regimes have been established for many fish species. In this study, we investigated the potential for a brief period of extreme flow to exert selection on the body shape of juvenile climbing Hawaiian gobiid fishes. Because of an amphidromous life history, juvenile gobies that complete an oceanic larval phase return to freshwater habitats, where they become adults. Returning juveniles often must scale waterfalls (typically with the use of a ventral sucker) in order to reach the habitats they will use as adults, thereby exposing these animals to brief periods of extreme velocities of flow. Hydrodynamic theory predicts that bodies with larger suckers and with lower heights that reduce drag would have improved climbing success and, thus, be well suited to meet the demands of the flows in waterfalls. To test the potential for the flow environment of waterfalls to impose selection that could contribute to differences in body shape between islands, we subjected juvenile Sicyopterus stimpsoni to climbing trials up artificial waterfalls (∼100 body lengths) and measured differences in body shape between successful and unsuccessful climbers. Waterfalls appear to represent a significant selective barrier to these fishes, as nearly 30% failed our climbing test. However, the effects of selection on morphology were not straightforward, as significant differences in shape between successful and unsuccessful climbers did not always match hydrodynamic predictions. In both selection experiments and in adult fish collected from habitats with different prevailing conditions of flow (the islands of Hawai'i versus Kaua'i), lower head heights were associated with exposure to high-flow regimes, as predicted by hydrodynamic theory. Thus, a premium appears to be placed on the reduction of drag via head morphology throughout the ontogeny of this

Fine coal in slurry form must be dewatered to minimize handling and transportation problems and be reduced to a desirable level for subsequent preparation of coal/water mixtures as a substitute utility fuel. The current practice is inadequate for the dewatering of fine coal, particularly for coal particles with sizes smaller than 400 mesh. Therefore, it is most desirable to develop improved mechanical methods for reducing the moisture content of fine coal. In the light of this, a fundamental study of the dewatering of fine coal/refuse was initiated in June 1979 and continued through 1984. The overall objective of the study is to seek improved methods of dewatering through a better understanding of the filtration and post-filtration processes. As a first step, efforts have been focused on the mechanism of dewatering in terms of the basic properties of coal (and refuse) particles and the microstructures of filter cakes, and their relations to filtration rate and final moisture content. Pittsburgh seam-Bruceton Mine coal was used as a base coal. During the past year, filter cakes from coals with widely varying size ranges were micrographically characterized. The effects of a number of surface active agents and of entrapped air bubbles on the filter cake properties were also studied. Modules of the network model for calculating single phase and two phase permeabilities were formulated and tested. The report is divided into four parts: summary and deliverables; work forecast for 1984-1985; detailed description of technical progress; and appendices. 21 refs., 55 figs., 17 tabs.

Characterization and genesis of waterfalls of the Presidente Figueiredo region, Northeast State of Amazonas, Brazil

Directory of Open Access Journals (Sweden)

AFONSO C. R. NOGUEIRA

2001-06-01

Full Text Available The waterfalls of the Presidente Figueiredo municipality represent a fascinating natural scenery of northeast state of Amazonas, northern Brazil. The falls, generally less than 10m high, are developed on siliciclastic rocks of the Nhamundá (Lower Silurian, and Manacapuru (Upper Silurian - Lower Devonian formations. Morphological and structural analyses of these features indicate that most of them originated through Quaternary neotectonics and are installed in NE-trending normal fault escarpments. Waterfalls also developed within pseudokarstic features, but are less frequent. The origin of the Presidente Figueiredo waterfalls probably goes back to the Neogene, when the region was submitted to laterization processes associated with a humid climate and a dense rainforest. These conditions favored the development of caves in quartzarenites of the Nhamundá Formation. During the Quaternary, the region was subjected to NE-trending normal faulting which displaced laterite layers, rivers and streams giving rise to waterfalls. These climatic and tectonic phenomena promoted intense relief dissection, as indicated by fault escarpment retreat and cave dismantlement, responsible for the present-day morphologic configuration.As cachoeiras da região de Presidente Figueiredo constituem um dos mais fascinantes cenários naturais do nordeste do Estado do Amazonas, norte do Brasil.

1983-01-01

This report presents the results of an environmental study carried out in the Qingua/Tunugliarfik Fiord area north of Narssarssuaq in July-October, 1982. The field work in the area included hydrographic investigations in the Tunugliarfik Fiord, fishery investigations in the Qingua river and a survey of the area likely to be affected by a hydro-electric plant. Information on commercial and sport fishing, hunting, sheep-farming, tourism, and conservation interests was also collected. The hydrographic investigations have shown that the inner part of Tunugliarfik is dominated by the estuarine circulation in the upper layer clearly influenced by the Qoroq Fiord. The lower 5 km of the river contain a large population of arctic char. The size of the migrating stock, i.e. excluding young and residual fish, is estimated at 10.000 - 20.000 fish. A series of waterfalls in the end of the Qingua valley constrains migrating fish to the lower river area. Beyond the falls two separate populations of stream-resident arctic char are found. Another non-migrant population is found in the Nordbo/Storesoe area. The arctic char fishery is locally of great importance. The fishery, which is carried out by use of gill net, is particularly extensive in the inner part of the Tunugliarfik Fiord. The Qiangua valley is also a popular site for anglers coming to the area by a daily boat from the hotel in Narssarssuaq. Besides char, great quantities of Greenland cod and Greenland halibut are caught in the fiord. The major part of the catch is consumed locally.

Full Text Available The aim of this contribution is to explore the historical influence of documentary films, in particular within the sphere of the public perception of the risks posed by asbestos. For this purpose, we study the British documentary Alice—A Fight for Life, the context in which it was produced, and the impact that its screening in 1982 had on British public opinion. The drama of the testimonies of some of the victims shown in the film and the visual treatment they received were determinant in heightening public awareness of asbestos risks. We also explore the effects of the documentary when it was shown in Spain in 1984.

Rhode Island crystalline repository project: Technical progress report, 1984-1986

International Nuclear Information System (INIS)

1986-01-01

A Nuclear Waste Fund established by the Nuclear Waste Policy Act of 1982 provided financial support to the State of Rhode Island for its participation in the high-level radioactive waste repository siting program. In 1984, the Office of the Governor set up a multidisciplinary Project Review Team consisting of staff from three State agencies and the University of Rhode Island. Members of the Review Team attended several meetings throughout the reporting period to voice their concerns about siting directly to the US Department of Energy (DOE). Written comments were also submitted on draft plans and reports. Many of Rhode Island's recommendations in these comments were later adopted. In May, 1986, Secretary of Energy John Herrington announced the suspension of the crystalline repository siting program. The remainder of the year was spent monitoring litigation challenging that decision and pending legislation. Administrative phase-down of the program was essentially complete by the close of the calendar year

In order to investigate if and how the vegetation has changed in consequence of the raised temperature in the biotest lake (which is the discharge area for the cooling water from the power plant), investigations of the distribution and production of macroscopic algae and higher vegetation have been carried out since 1974. This report presents the results from the period 1984-1986. The investigations have shown that not only the temperature, but also the absence of ice cover, the water stream through the biotest lake and the reduced exposition caused by the embankment, are of importance for the vegetation in the lake. The vegetation has changed in the following aspects: The area of the shore vegetation has been continuously increasing. In 1982 it was c. 6200 m 2 , 1984 it was c. 9850 m 2 and 1985 c. 11000 m 2 , mainly consisting of Phragmites communis. Most of the shore line is now occupied by vegetation. The standing crop was found to have decreased since the power plants started. 1980 there was 74 g/m 2 dry weight and in 1986 28 g/m 2 . Among the most important species of macroscopic underwater vegetation Chara spp and Potamogeton pectinatus show a decrease of standing crop while Cladophora glomerata and Vaucheria sp have increased since the investigation started.

Kidani, Taichi; Koyama, Kazuya; Mizuno, Shuntaro

2012-10-01

We study multifield Dirac-Born-Infeld (DBI) inflation models with a waterfall phase transition. This transition happens for a D3 brane moving in the warped conifold if there is an instability along angular directions. The transition converts the angular perturbations into the curvature perturbation. Thanks to this conversion, multifield models can evade the stringent constraints that strongly disfavor single field ultraviolet (UV) DBI inflation models in string theory. We explicitly demonstrate that our model satisfies current observational constraints on the spectral index and equilateral non-Gaussianity as well as the bound on the tensor to scalar ratio imposed in string theory models. In addition, we show that large local type non-Gaussianity is generated together with equilateral non-Gaussianity in this model.

Analyzing Agile Development – from Waterfall Style to Scrumban

Full Text Available The spectacular evolution of information and communications technology in the last two decades and the growing obvious chase of utopian maximization of profit by economic organizations have made an impact on various fields, including that of methodological instruments regarding the lifecycle of software development. We will speak about the necessity of organizational ability to adapt to continuously changing market conditions, which leads undoubtedly to acquiring functional flexibility and, in the end, of business agility. Also, the agility of a business (not only in software development is supported by the manifestation of agility on all three architectural levels: business, informational, technological. In this study we aim to identify the elements that impact on agility in developing software products, in a gradual approach, from the traditional waterfall model towards approaches like Scrumban. Additionally, we will understand the social dimension of using agile methodologies in software development projects and the main barriers in adopting such methodologies.

Chenoweth, W.L.

1983-01-01

Slippage in demand, increasing costs, and low spot market prices continued to influence the uranium industry during 1982. The supply of uranium exceeds the current demand and, as a result, exploration for uranium declined in the United States for the fourth straight year. During 1982, 92 companies spent $73.86 million on uranium exploration, including 6.1 million ft of surface drilling. This drilling was done mainly in the producing areas and in the areas of recent discoveries. During the year, a significant discovery was announced in south-central Virginia, the first major discovery in the eastern United States. Production of uranium concentrate declined in 1982, when 1,343 short tons of uranium oxide were produced. Numerous mines and 4 mills were closed during the year. Domestic uranium reserves, as calculated by the Department of Energy, decreased during 1982, mainly because of increasing production costs and the lack of exploration to find new reserves. Exploration for uranium in foreign countries also declined during 1982. Canada and Australia continue to dominate the long-term supply

Can massive primordial black holes be produced in mild waterfall hybrid inflation?

International Nuclear Information System (INIS)

Kawasaki, Masahiro; Tada, Yuichiro

2016-01-01

We studied the possibility whether the massive primordial black holes (PBHs) surviving today can be produced in hybrid inflation. Though it is of great interest since such PBHs can be the candidate for dark matter or seeds of the supermassive black holes in galaxies, there have not been quantitatively complete works yet because of the non-perturbative behavior around the critical point of hybrid inflation. Therefore, combining the stochastic and δ N formalism, we numerically calculated the curvature perturbations in a non-perturbative way and found, without any specific assumption of the types of hybrid inflation, PBHs are rather overproduced when the waterfall phase of hybrid inflation continues so long that the PBH scale is well enlarged and the corresponding PBH mass becomes sizable enough.

The Nuclear Science Center is operated by the Texas Engineering Experiment Station as a service to the Texas A and M University System and the State of Texas. The facility is available to the University, other educational institutions, governmental agencies, and private organizations and individuals. Reactor utilization decreased from 1983 as indicated by a slightly smaller number of samples irradiated and of total irradiations. Core VIII, established in December 1982, was used throughout 1984. Several major facility projects modifications, and improvements were completed during the past year. Experimentally the Beam Port No. 4 reflector and shutter was improved, the pulsing instrumentation is being expanded, and the pneumatic system controller developed for Lab No. 4 is now in use in the Center for Trace Characterization (CTC) and Shell Development labs. Several operational problems occurred in 1984 but did not result in a significant loss of reactor operating time. During this reporting period there were no changes made to the site area; however, there has been made a proposal to extend the runway at nearby Easterwood Airport such tha larger aircraft can be accommodated. This extension should occur in 1985 and should have no affect on the air traffic patterns relative to the NSC. Administratively during 1984 efforts have been made to stabilize the reactor operations staff following the mid year resignations of both a Reactor Supervisor and Manager of Reactor Operations. A long term replacement has been hired to fill the vacated Reactor Supervisor position; however, the manager position has not yet been filled and those duties have been assumed by the Assistant Director

Local adaptation despite high gene flow in the waterfall-climbing Hawaiian goby, Sicyopterus stimpsoni.

Environmental heterogeneity can promote the emergence of locally adapted phenotypes among subpopulations of a species, whereas gene flow can result in phenotypic and genotypic homogenization. For organisms like amphidromous fishes that change habitats during their life history, the balance between selection and migration can shift through ontogeny, making the likelihood of local adaptation difficult to predict. In Hawaiian waterfall-climbing gobies, it has been hypothesized that larval mixing during oceanic dispersal counters local adaptation to contrasting topographic features of streams, like slope gradient, that can select for predator avoidance or climbing ability in juvenile recruits. To test this hypothesis, we used morphological traits and neutral genetic markers to compare phenotypic and genotypic distributions in recruiting juveniles and adult subpopulations of the waterfall-climbing amphidromous goby, Sicyopterus stimpsoni, from the islands of Hawai'i and Kaua'i. We found that body shape is significantly different between adult subpopulations from streams with contrasting slopes and that trait divergence in recruiting juveniles tracked stream topography more so than morphological measures of adult subpopulation differentiation. Although no evidence of population genetic differentiation was observed among adult subpopulations, we observed low but significant levels of spatially and temporally variable genetic differentiation among juvenile cohorts, which correlated with morphological divergence. Such a pattern of genetic differentiation is consistent with chaotic genetic patchiness arising from variable sources of recruits to different streams. Thus, at least in S. stimpsoni, the combination of variation in settlement cohorts in space and time coupled with strong postsettlement selection on juveniles as they migrate upstream to adult habitats provides the opportunity for morphological adaptation to local stream environments despite high gene flow. © 2014

Finding paradise: cues directing the migration of the waterfall climbing Hawaiian gobioid Sicyopterus stimpsoni.

A series of waterfall-climbing trials were conducted to identify cues that direct the climbing of juvenile Sicyopterus stimpsoni. In the first experiment, whether climbing juveniles preferentially ascend water sources with conspecifics or whether the presence of just stream water is sufficient to attract fish to ascend a climbing path were assessed. In the second experiment, whether climbing juveniles create a trail of mucus that facilitates the ability of conspecifics to follow their lead was determined. The results indicate that juvenile S. stimpsoni are less likely to climb in waters devoid of organic cues but are strongly attracted to stream water with or without the odour of conspecifics. Once climbing, performance did not differ for juveniles climbing in differing water choices, suggesting an all-or-nothing commitment once climbing commences. Climbing S. stimpsoni did produce a mucous trail while climbing that was associated with a mucous gland that dramatically increases in size just prior to juveniles gaining the ability to climb. The trail was not followed closely by subsequent juveniles traversing the same channel, however, suggesting only weak trail-following in waterfall climbing S. stimpsoni. Previous genetic studies suggest that juvenile S. stimpsoni do not home to natal streams in the face of strong near-shore oceanic currents. Instead, these fish appear primarily to rely on cues that suggest the presence of organic growth in streams, a factor that may indicate suitable habitat in an ever-changing stream environment but which may also be vulnerable to interference through human activity. © 2012 The Authors.

Arms control in space: workshop proceedings, Washington, DC, January 30-31, 1984

International Nuclear Information System (INIS)

1984-05-01

In late 1982 and early 1983, the Subcommittee on Arms Control, Oceans, International Operations, and Environment of the Senate Committee on Foreign Relations held hearings on space weapons and arms control. To explore these issues further in a discussion format not easily achieved in hearings, Sen. Larry Pressler, Chairman of the Subcommittee, asked OTA to conduct a workshop focusing on antisatellite (ASAT) weapons as one aspect of space arms control. The workshop held in Washington, DC on January 30 and 31, 1984, provided an opportunity for technical, diplomatic, military, and policy-analysis experts to interact, think out loud, and build each other's ideas. The workshop was organized into six sessions, although issues involving anti-satellite weapons and arms control are not easily compartmentalized into distinct subject areas. Each session was introduced by a 10- or 15-minute informal oral presentation which set the stage for further discussion. This workshop proceedings volume is organized along the same divisions as the sessions, with some rearrangement

Species exposed to extreme environments often exhibit distinctive traits that help meet the demands of such habitats. Such traits could evolve independently, but under intense selective pressures of extreme environments some existing structures or behaviors might be coopted to meet specialized demands, evolving via the process of exaptation. We evaluated the potential for exaptation to have operated in the evolution of novel behaviors of the waterfall-climbing gobiid fish genus Sicyopterus. T...

Rate of bedrock channel incision by waterfall retreat and landscape response constrained by cosmogenic 3He, Kauai, Hawaii

Science.gov (United States)

Mackey, B. H.; Lamb, M. P.; Scheingross, J. S.; Farley, K. A.

2011-12-01

Channel incision and knickpoint retreat are the drivers of landscape evolution, yet we are still challenged to quantify the rate and processes by which rivers cut into rock. The Napali Coast on the northwestern side of Kauai, Hawaii, has multiple linear channels incising >200 m into the shield volcano surface. The channels have well-constrained initial conditions, including original topography, and relatively uniform layered basalt of known age (~4.5 Ma), which have attracted previous studies of channel evolution (e.g., Seidl et al., 1994, 1997). Many channels feature prominent waterfalls, although the mechanism of knickpoint initiation (submarine landslide vs cliff erosion) and subsequent retreat remain ambiguous. Motivated by these knowledge gaps and recent advances in cosmogenic helium geochronology, we revisited the Kaulaula Valley, a 9 km long narrow valley, beheaded on its upslope extent by the Waimea Canyon, and ending near the coast at the northern Mana Plain. Four kilometers up the canyon is a prominent 40 m high vertical knickpoint, dividing the valley into strongly contrasting geomorphic domains. The boulder-lined channel below the knickpoint is linear, steep (15%), and confined to a narrow valley with steep rocky cliffs (average slope 31°). Large, >2 m diameter angular boulders in the lower section of channel show evidence of mobility from debris flows. Above the knickpoint, average channel gradient is reduced (9%), bed load is much finer, and convex, soil-mantled hillslopes have a consistently lower mean slope of 18°. We constrained the exposure age of 18 features (in-channel boulders, stable boulders on terraces, and in-channel bedrock) along the length of the channel, by analysis of cosmogenic 3He in olivine phenocrysts. Cosmogenic exposure ages are oldest near the coast (80 ka) and systematically decrease with upstream distance towards the waterfall (model of knickpoint retreat and downstream terrace abandonment advocated by Seidl (1997), and we

Morphodynamics of Travertine Dam/Waterfall Growth due to the Interaction of Biological Activity, Water Flow and Limestone Emplacement

Science.gov (United States)

Izumi, N.; Parker, G.

2012-12-01

Plitvice Lakes in Croatia are characterized by a step-like train of lakes and waterfalls. The waterfalls are located at the crests of naturally-emplaced dams. The top of each dam grows upward at the rate of a few millimeters per year. It is thought that the upward growth of these dams is caused by the interaction of water flow and biological activity, resulting in the precipitation of dissolved limestone. Dam evolution is initiated by the growth of mosses that favor swift, shallow water. Bacteria that inhabit the roots of the moss excrete solid limestone (travertine) from the water. The limestone fossilizes the moss, and then more moss grows on top of the travertine deposit. In this way, the natural dam can grow over to 10 m high, impounding the water behind it to form a lake. We propose a simple model to explain the formation of natural limestone dams by the interaction between water flow and biologically-mediated travertine deposition. We assume for simplicity that light is the only factor determining the growth of moss, which is then colonized by travertine-emplacing bacteria. We also assume that the water is saturated with dissolved limestone, so that the process is not limited by limestone availability. Photosynthesis, and thus the growth rate of moss are crudely approximated as decreasing linearly with depth. We employ the shallow water equations to describe water flow over the dam. In order to obtain a profile of permanent form for a dam migrating upward and downstream at constant speed, we solve the problem in a moving coordinate system. When water flows over the dam, it is accelerated in the streamwise direction, and the water surface forms a backwater curve. The flow regime changes from Froude-subcritical to Froude-supercritical at a point slightly downstream of the crest of the dam. Farther downstream, the flow attains a threshold velocity beyond which moss is detached. This threshold point defines the downstream end of the active part of the dam. The

Powers, Patrick D.; Orsborn, John F.

1985-08-01

This volume covers the broad, though relatively short, historical basis for this project. The historical developments of certain design features, criteria and research activities are traced. Current design practices are summarized based on the results of an international survey and interviews with agency personnel and consultants. The fluid mechanics and hydraulics of fishway systems are discussed. Fishways (or fishpasses) can be classified in two ways: (1) on the basis of the method of water control (chutes, steps (ladders), or slots); and (2) on the basis of the degree and type of water control. This degree of control ranges from a natural waterfall to a totally artificial environment at a hatchery. Systematic procedures for analyzing fishways based on their configuration, species, and hydraulics are presented. Discussions of fish capabilities, energy expenditure, attraction flow, stress and other factors are included.

Formation of primordial black holes from non-Gaussian perturbations produced in a waterfall transition

Science.gov (United States)

Bugaev, Edgar; Klimai, Peter

2012-05-01

We consider the process of primordial black hole (PBH) formation originated from primordial curvature perturbations produced during waterfall transition (with tachyonic instability), at the end of hybrid inflation. It is known that in such inflation models, rather large values of curvature perturbation amplitudes can be reached, which can potentially cause a significant PBH production in the early Universe. The probability distributions of density perturbation amplitudes in this case can be strongly non-Gaussian, which requires a special treatment. We calculated PBH abundances and PBH mass spectra for the model and analyzed their dependence on model parameters. We obtained the constraints on the parameters of the inflationary potential, using the available limits on βPBH.

Thermal inflation with a thermal waterfall scalar field coupled to a light spectator scalar field

Science.gov (United States)

Dimopoulos, Konstantinos; Lyth, David H.; Rumsey, Arron

2017-05-01

A new model of thermal inflation is introduced, in which the mass of the thermal waterfall field is dependent on a light spectator scalar field. Using the δ N formalism, the "end of inflation" scenario is investigated in order to ascertain whether this model is able to produce the dominant contribution to the primordial curvature perturbation. A multitude of constraints are considered so as to explore the parameter space, with particular emphasis on key observational signatures. For natural values of the parameters, the model is found to yield a sharp prediction for the scalar spectral index and its running, well within the current observational bounds.

Annual report 1984

International Nuclear Information System (INIS)

Nuclear power technology, isotope technology and basic research in physics comprises the nuclear activities of Institute for Energy Technology (IFE). In 1984 the Institute entered into an agreement with the present foreign signatories (comprising more than 40 organisations from 10 participating countries) for the continuation of the OECD Halden Project for the three year period from 1985 to 1987. IFE's share of the total budget is appr. 25%. The project's fuel investigations have in 1984 particularly emphasised the characterisation of long term effects with regard to efficiency and operational safety, and the determination of reliability and durability in the case of accident with the loss of cooling water. During 1984 the new experimental reactor control room of the Halden Project was put in operation. The screen based control room, connected to a detailed simulator of a PWR, is intended for experiments in the field of man-machine communication, information presentation, testing of specific systems and training of operators. A testing of alarm systems carried out during 1984 shows that the filtering of alarms is an effective means to ensure that the operator concentrates on the most relevant information during disruptions in the plant operations, and that the use of mimic diagrams facilitates the indentification of alarm situations. Apart from isotope production, the efforts of the isotope laboratories have been concentrated on the development of two completely new radiopharmaceuticals, with the aid of which a blood sample can be marked with a radioactive tracer for the location of abcesses, states of inflammation or blood clots. Research in basic physics has mainly been based on the use of neutron irradiations from the JEEP II reactor for the investigation of the structure and dynamics of solid state materials

Environmental pressures may vary over the geographic range of a species, exposing subpopulations to divergent functional demands. How does exposure to competing demands shape the morphology of species and influence the divergence of populations? We explored these questions by performing selection experiments on juveniles of the Hawaiian goby Sicyopterus stimpsoni, an amphidromous fish that exhibits morphological differences across portions of its geographic range where different environmental pressures predominate. Juvenile S. stimpsoni face two primary and potentially opposing selective pressures on body shape as they return from the ocean to freshwater streams on islands: (1) avoiding predators in the lower reaches of a stream; and (2) climbing waterfalls to reach the habitats occupied by adults. These pressures differ in importance across the Hawaiian Islands. On the youngest island, Hawai'i, waterfalls are close to shore, thereby minimizing exposure to predators and placing a premium on climbing performance. In contrast, on the oldest major island, Kaua'i, waterfalls have eroded further inland, lengthening the exposure of juveniles to predators before migrating juveniles begin climbing. Both juvenile and adult fish show differences in body shape between these islands that would be predicted to improve evasion of predators by fish from Kaua'i (e.g., taller bodies that improve thrust) and climbing performance for fish from Hawai'i (e.g., narrower bodies that reduce drag), matching the prevailing environmental demand on each island. To evaluate how competing selection pressures and functional tradeoffs contribute to the divergence in body shape observed in S. stimpsoni, we compared selection imposed on juvenile body shape by (1) predation by the native fish Eleotris sandwicensis versus (2) climbing an artificial waterfall (∼100 body lengths). Some variables showed opposing patterns of selection that matched predictions: for example, survivors of predation had

The Hot Springs Fork of the Collawash River is a major sub-drainage in the Clackamas River drainage. Emphasis species for natural production are spring chinook, coho salmon, and winter steelhead. Increased natural production appears limited by a lack of quality rearing habitat. Habitat complexity over approximately 70% of accessible area to anadromous fish has been reduced over the last 40 years by numerous factors. Natural passage barriers limit anadromous fish access to over 7 miles of high quality habitat. In the first year of a multi-year effort to improve fish habitat in the Hot Springs Fork drainage, passage enhancement on two tributaries and channel rehabilitation on one of those tributaries was completed. Three waterfalls on Nohorn Creek were evaluated and passage improved on the uppermost waterfall to provide steelhead full access to 2.4 miles of good quality habitat. The work was completed in October 1985 and involved blasting three jump pools and two holding pools into the waterfall. On Pansy Creek, four potential passage barriers were evaluated and passage improvement work conducted on two logjams and one waterfall. Minor modifications were made to a waterfall to increase flow into a side channel which allows passage around the waterfall. Channel rehabilitation efforts on Pansy Creek (RM 0.0 to 0.3) to increase low flow pool rearing habitat and spawning habitat including blasting five pools into areas of bedrock substrate and using a track-mounted backhoe to construct instream structures. On site materials were used to construct three log sills, three boulder berms, a boulder flow deflector, and five log and boulder structures. Also, an alcove was excavated to provide overwinter rearing habitat. Pre-project monitoring consisting of physical and biological data collection was completed in the project area.

THE BACTERIOLOGICAL AND PHYSICO-CHEMICAL STUDIES ON OLUMIRIN WATERFALL ERIN- IJESHA, OSUN STATE, NIGERIA

Full Text Available The potability and qualities of Olumirin waterfall, Erin-Ijesa were investigated by determining the total bacteria and coliform count with antibiotic susceptibility of the isolated bacteria and physico-chemical qualities of the water samples. Total bacteria and coliform enumeration were determined using pour plating and multiple tube techniques, the antibiotic susceptibility were carried out using disc diffusion method, while physico-chemical and mineral studies were also carried out using standard methods. The mean total viable count of the water samples ranged 14.8 x 102 CFU.ml-1 - 21.3 x 103 CFU.ml-1 while the coliform count ranged 13 -175 MPN/100ml. The identified bacteria isolates and their percentage distribution were E.coli (43.1%, Klebsiella spp (20.7%, Proteus spp (12.1%, Salmonella spp (6.99%, Pseudomonas spp (5.17%, Shigella spp (6.9%, and Enterococcus spp (5.17 %. Antibiotic resistance shown by bacteria isolates were exhibited as follow; Nalixidic acid (31%, Ampicilin (76%, Cotrimoxazole (60%, Gentamicin (19%, Nitrofurantoin (24%, Colitin (48%, Streptomycin (34% and tetracycline (52%. 82.8% of the isolate exhibited multiple antibiotic resistance. The physico-chemical analysis also revealed the presence of some mineral elements in the water samples. The mineral value of the water samples include; magnesium (84.8 - 93.4 mg.L-1, phosphate (12.6 - 17.1 mg.L-1, sodium (47.8 - 87.6 mg.L-1, potassium (76.6 - 104.5 mg.L-1, chloride (59.0 - 90.2 mg.L-1, zinc (0.75 - 1.82 mg.L-1, lead (0.12 - 0.33 mg.L-1, iron (0.52 - 0.60 mg.L-1, copper (0.12 - 0.27 mg.L-1 while nickel and arsenic were not detected in any of the water samples. Comparing the experimental results with the international water standard for natural water, the waterfall is not fit for consumption or for any domestic purpose unless being treated. Also, problems that may arise from the resistance bacteria strains can be tackled while the new antibiotics can also be developed.

The surface and deep structure of the waterfall illusion.

Wade, Nicholas J; Ziefle, Martina

2008-11-01

The surface structure of the waterfall illusion or motion aftereffect (MAE) is its phenomenal visibility. Its deep structure will be examined in the context of a model of space and motion perception. The MAE can be observed following protracted observation of a pattern that is translating, rotating, or expanding/contracting, a static pattern appears to move in the opposite direction. The phenomenon has long been known, and it continues to present novel properties. One of the novel features of MAEs is that they can provide an ideal visual assay for distinguishing local from global processes. Motion during adaptation can be induced in a static central grating by moving surround gratings; the MAE is observed in the static central grating but not in static surrounds. The adaptation phase is local and the test phase is global. That is, localised adaptation can be expressed in different ways depending on the structure of the test display. These aspects of MAEs can be exploited to determine a variety of local/global interactions. Six experiments on MAEs are reported. The results indicated that relational motion is required to induce an MAE; the region adapted extends beyond that stimulated; storage can be complete when the MAE is not seen during the storage period; interocular transfer (IOT) is around 30% of monocular MAEs with phase alternation; large field spiral patterns yield MAEs with characteristic monocular and binocular interactions.

The low energy electronic structure of Sr2IrO4 has been well studied and understood in terms of an effective Jeff = 1/2 Mott insulator model. However, little work has been done in studying its high energy electronic behaviors. Here we report a new observation of the anomalous high energy electronic structure in Sr2IrO4. By taking high-resolution angle-resolved photoemission measurements on Sr2IrO4 over a wide energy range, we have revealed for the first time that the high energy electronic structures show unusual nearly-vertical bands that extend over a large energy range. Such anomalous high energy behaviors resemble the high energy waterfall features observed in the cuprate superconductors. While strong electron correlation plays an important role in producing high energy waterfall features in the cuprate superconductors, the revelation of the high energy anomalies in Sr2IrO4, which exhibits strong spin-orbit coupling and a moderate electron correlation, points to an unknown and novel route in generating exotic electronic excitations.

Darden, C.W. III.

1982-01-01

On September 7th, 1982, following four years of planning and construction, the magnetic solenoid detector ARGUS was moved into one of the two interaction regions of the electron-positron storage ring DORIS. A month later the ring started delivering luminosity for physics research, specifically, the study of the formation and decay of members of the Upsilon family of mesons. These mesons are bound states, b anti b, of the heaviest of the five known quarks and therefore of considerable interest. This report describes the progress made during the year from March 1982 to March 1983 with emphasis on the experience gained during the first running period

Solar-terrestrial disturbances in June-September 1982, 5

The x-ray detector on the SMS-GOES satellite observed 77 solar x-ray flares (1 - 8A) with flux above 10 -5 W/m 2 in June, 1982, and 33 SIDs with importance above 2 were observed in Hiraiso, Japan. However, the geomagnetic storm with Dst above 100 nT did not occur at that time since most solar flares occurred near the east rim of the sun. These solar active regions lasted for 5 solar rotations, then, the great geomagnetic storms with Dst above 100 nT occurred on July 13 - 15, September 5 - 7 and September 21 - 23, 1982. These geomagnetic storms were preceded by the solar flares of importance above 2B occurred in the central part of the solar disc. From September 26 to 27, 1982, a great geomagnetic storm which was not accompanied by solar flare occurred. This paper summarized the studies on solar-terrestrial events from June to September, 1982, made by the space physics and aeronomy groups of the Radio Research Laboratories, Japan. The solar flares occurred on July 12, September 4 and 19, 1982, the geomagnetic storms corresponding to them, the cosmic ray storms observed on July 13 - 19, September 6 - 9 and 21 - 26, 1982, global equivalent current system and others are reported.

Aeikaes, T.; Oehberg, A.; Ryhaenen, V.

1985-02-01

Industrial Power Company Ltd (TVO) drilled in the spring 1984 a 1001 m deep borehole, diameter 56 mm, in Lavia. The borehole is used during the years 1984-85 for developing and testing research methods and equipment needed in site investigations of spent fuel final disposal in the future. In 1984 hydraulical and geophysical tests were made and groundwater samples were taken. The drilling site is a wide outcropped area in the northern part of the porphyritic granite formation of Lavia. Geological and fracture mapping as well as geophysical measurements on the surface were made in the area surrounding the drilling site. The bedrock consists of homonous porphyritic granite, in which quartzdiorite occurs in thin incalations. Magnetic or electric anomalies were not observed. Fracture frequency is low and the fractures appear mainly in two sets. The rock types vary in the borehole from porphyritic granite to diorite. Due to slight mineralogical variations, the diorite is either granodiorite, quartzdiorite or tonalite. Granite occurs as veins. Hydraulic conductivity was measured systematically with a packer separation of 30 m between the depths 73-973 m. Hydraulic conductivity is generally 10 -10 -10 -11 m/s. Electric, radiometric, magnetic and acoustic measurements were made in the borehole. In addition, the caliper and the temperature of the borehole were measured. The results of these geophysical measurements indicate the properties of rock types and fracturing in the borehole. On the basis of the results e.g. fracture porosity was interpreted. The results of acoustic tube wave measurement correlate well with hydraulic conductivity. Water samples were taken from four depths. The deepest level was 910 m. The samples were taken with a packer separation of 5 m. In the water analyses it was observed that at several depths remarkable amounts of flushing water from drilling were still remaining in the rock

1982 Annual Energy Review

International Nuclear Information System (INIS)

1983-04-01

Total energy consumption in the United States equaled 70.9 quadrillion British thermal units (Btu) in 1982, a decline of 4.1% compared to 1981. Depressed economic activity was a major factor in reducing total energy demand. However, conservation also played a role as energy consumption per dollar of GNP continued to fall. Most of the decline in energy use involved petroleum and natural gas. Reduced petroleum demand translated into a 21.7% reduction in net petroleum imports. Natural gas demand and production fell, prompted by reduced economic activity and a substantial increase in prices. Crude oil prices fell for the first time in more than a decade. Weakened market conditions adversely affected the rate of domestic oil and gas exploration and development activities. Nonetheless, domestic crude oil production rose 1.2%. International activities were highlighted by a decline in crude oil production, especially by members of the Organization of Petroleum Exporting Countries (OPEC), a decrease in crude oil prices, and a substantial increase in electricity production by nuclear-powered utility plants in non-Communist countries. Energy production in the United States in 1982 remained essentially unchanged from that of 1981, as small gains in hydroelectric power and nuclear power production were offset by losses in natural gas production. For the third straight year, energy consumption in the United States declined. Whereas declines in 1980 and 1981 resulted primarily from consumer response to higher prices and conservation, the 1982 decline reflected primarily an economic slowdown, especially in industry. Annual per capita consumption fell to 306 million Btu, the lowest level since 1967. Changes in energy prices in 1982 were mixed. Whereas most petroleum prices declined, prices of natural gas, coal, and electricity rose

Jordan, N.G.; Livdahl, P.V.

1984-02-01

It is of current interest to examine the costs incurred to date to build Fermi National Accelerator Laboratory and to determine what those costs are when stated in FY 1984 constant dollars. The appended tables are in support of this exercise and are based on all costs for Equipment items (reduced by obsolescence) and all Plant Projects which have been appropriated through FY 1984. Also included are non-plant costs which are required to complete the Energy Saver, Tevatron I and II projects (i.e., Equipment and R and D in support of Construction). This study makes the assumption that all funding through FY 1984 will have been costed by the end of FY 1986. Those costs incurred in FY 1985 and FY 1986 have been deflated to FY 1984 dollars. See Appendix A for the DOE inflation factors used in the conversion to FY 1984 dollars. The costs are identified in three categories. The Accelerator Facilities include all accelerator components, the buildings which enclose them and utilities which support them. The Experimental Facilities include all beam lines, enclosures, utilities and experimental equipment which are usable in current experimental programs. The Support Facilities include lab and office space, shops, assembly facilities, roads, grounds and the utilities which do not specifically support the Accelerator or Experimental Facilities, etc

1984 annual report

International Nuclear Information System (INIS)

1985-04-01

Ontario Hydro supplied 122.9 billion kilowatt-hours of electricity in 1984 to meet provincial and export demands. Total primary energy demand was 112.3 billion kWh, an increase of 5.9 percent. The year's peak demand of 18.9 kW occurred on January 12. In 1984 nuclear generating stations produced 40.4 billion kWh, 32.8 percent of the total energy supplied by Ontario Hydro. The additional output of two new nuclear units, Pickering-6 and Bruce-6, more than offset the loss of production caused by Pickering units 1 and 2 being out of service all year for retubing. In May, Atomic Energy of Canada Ltd. removed its Douglas Point nuclear station from service since it was no longer economic to operate the station. Nuclear plants produced electricity at an average cost of 2.2 cents per kWh, compared to 3.4 cents for fossil-fuelled plants

Full Text Available The Emas waterfall in Mogi-Guaçu River is regionally recognized as an important fishing spot and touristic place. The first reports of the professional and sport fishing there date back from the 30's, which is the same period when the tourism took place. The present paper provides an environmental valuation of this place and an assessment of the differences among the major groups of people using the area. During 2006 we interviewed 33 professional fishers, 107 sport fishers, 45 tourists and 103 excursionists in order to estimate the Willingness to Pay (WTP for each category and to analyze the influence of socioeconomic factors by means of logistic regressions and ANCOVAs. The WTP of professional fisher was significantly influenced by age and education, and the WTP for the sport fishers was influenced by the family income. The variables that influenced the tourists' and excursionists' WTP were sex and education. The total annual aggregated value to maintain the waterfall in the current conditions was estimated in US$ 11.432.128, and US$ 55.424.283 to restore it.A Cachoeira de Emas, no Rio Mogi-Guaçu, é reconhecida regionalmente como um importante local para a pesca e o turismo.

Environmental surveillance activities performed by the Pacific Northwest Laboratory for the Department of Energy's Hanford Site for 1984 are discussed in this report. Samples of environmental media were collected in support of the Hanford Environmental Monitoring Program to determine radionuclide concentrations in the Hanford environs. Radiological impacts in terms of radiation dose equivalents as a result of Hanford operations are also discussed. Gross beta radioactivity concentrations in airborne particulates at all sampling locations were lower in 1984 than during 1983 as a result of declining levels of worldwide fallout. Slightly higher levels of 85 Kr and 129 I were noted at several onsite and offsite locations. The sampling location in close proximity to the PUREX plant also detected increased 3 H. Very low levels of radionuclides were detected in samples of Columbia River water during 1984. An extensive groundwater monitoring program was performed for the Hanford Site during 1984. The 3 H and nitrate plumes continued to move slowly toward the Columbia River. All 3 H results were within applicable concentration guides. Samples of deer, rabbits, game birds, waterfowl and fish were collected onsite or in the Columbia River at locations where the potential for radionuclide uptake was most likely, or at the nearest locations where wildlife samples were available. Radioisotope levels were measured. Dose rates from external penetrating radiation measured in the vicinity of residential areas were similar to those observed in the previous years, and no contribution from Hanford activities could be identified. An assessment of the 1984 potential radiological impacts attributable to the Hanford operations indicated that measured and calculated radiation doses to the public continued to be low, and well below applicable regulatory limits. 21 refs., 48 figs., 83 tabs

Several ion whistlers were observed by the polar orbiting satellites, ISIS's during geomagnetic storms associated with large solar flares in 1982. It seems that the proton density ratio to the total ions deduced from the crossover frequency of the trans-equatorial ion whistlers observed at geomagnetic low latitudes during the main phase of the geomagnetic storm on July 14th 1982 was lower than the usual density rate. An abnormal pattern seen on the time-compressed dynamic spectra for September 6 th 1982 suggests existence of effects by the component 3 He + in a quite small amount. (author)

Investigation of the solution properties of the transuranium elements. Final report, July 1, 1979-September 30, 1984

International Nuclear Information System (INIS)

Ensor, D.D.

1984-01-01

This final report summarizes the significant results obtained during our investigation of the fundamental solution properties of the transuranium elements for the period July 1, 1979 to September 30, 1984. Primary interest of the project was the development of improved separation methods for the trivalent actinide elements from each other and from the chemically similar trivalent lanthanide elements using solvent extraction techniques. Two different synergistic systems were investigated. The combination of dialkynaphthalenesulfonic acids with a crown ether or an oxime was an attempt to combine the excellent ion exchange properties of the sulfonic extractant with a synergistic agent which would improve the selectivity of the extraction system. The results showed that the presence of the crown ether improved the extraction of the light lanthanides by approximately 50% while the heavy lanthanides were unaffected. The use of the oxime in combination with the sulfonic acid extractant showed significant enhancement for all metal ions studied but little, if any, selectivity. The use of novel oxygen donors as synergistic agents in combination with thenoyltrifluoroacetone provided significant enhancement for the extraction of trivalent lanthanides and actinides. The data showed the best selectivity was obtained using a linear polyether as the synergistic agent. The crown ether and the cryptand showed significant synergistic capabilities but lacked selectivity due to their rigid cavities. The results of this study indicate that the linear polyether is more promising as a synergistic agent because of its flexibility and ease of chemical modification of the end groups. 10 figures, 5 tables

Frozen waterfall (or ice cascade) growth and decay: a thermodynamic approach

Science.gov (United States)

Gauthier, Francis; Montagnat, Maurine; Weiss, Jérôme; Allard, Michel; Hétu, Bernard

2013-04-01

The ice volume evolution of an ice cascade was studied using a thermodynamic model. The model was developed from meteorological data collected in the vicinity of the waterfall and validated from ice volume measurements estimated from terrestrial LiDAR images. The ice cascade forms over a 45 m high rockwall located in northern Gaspésie, Québec, Canada. Two stages of formation were identified. During the first stage, the growth is mainly controlled by air convection around the flowing and freefalling water. The ice cascade growth rate increases with the decreasing air temperature below 0°C and when the water flow reaches its lowest level. During the second stage, the ice cascade covers the entire rockwall surface, water flow is isolated from the outside environment and ice volume increases asymptotically. Heat is evacuated from the water flow through the ice cover by conduction. The growth is mainly controlled by the radiation energy balance but more specifically by the longwave radiation emitted at the ice surface during the night. In spring, melting of the ice cascade is clearly dependant on the sensible heat carried by the increasing water flow and the diffuse solar radiation received at the ice surface during the day.

Rapid Gorge Formation in an Artificially Created Waterfall

Anton, L.; Mather, A. E.; Stokes, M.; Munoz Martin, A.

2014-12-01

A number of studies have examined rates of gorge formation, nick point retreat, and the controls on those rates via bedrock erodibility, the effectiveness of bedrock erosion mechanisms and the role of hillslope processes. Most findings are based on conceptual / empirical models or long term landscape analysis; but studies of recent quantifiable events are scarce yet highly valuable. Here we present expert eye witness account and quantitative survey of large and rapid fluvial erosion events that occurred over an artificially created waterfall at a spillway mouth. In 6 years a ~270 m long, ~100 m deep and ~100 to 160 m wide canyon was carved, and ~1.58 x106 m3 of granite bedrock was removed from the spillway site. Available flow data indicates that the erosion took place under unremarkable flood discharge conditions. The analysis of historic topographic maps enables the reconstruction of the former topography and successive erosion events, enabling the quantification of bedrock erosion amounts, and rates. Analysis of bedrock erodibility and discontinuity patterns demonstrates that the bedrock is mechanically strong, and that similar rock strength and fracture patterns are found throughout the region. It is apparent that structural pre-conditioning through fracture density and orientation in relation to flow and slope direction is of paramount importance in the gorge development. The presented example provides an exceptional opportunity for studying the evolution process of a bedrock canyon and to precisely measure the rate of bedrock channel erosion over a six year period. Results illustrate the highly episodic nature of the erosion and highlight several key observations for the adjustability of bedrock rivers. The observations have implications for the efficiency of bedrock erosion and raise important questions about incision rates, driving mechanisms and timescale assumptions' in models of landscape change.

Petrologic characteristics of the 1982 and pre-1982 eruptive products of El Chichon volcano, Chiapas, Mexico.

Studies on a suite of rocks from this volcano indicate that the juvenile materials of the 1982 and pre-1982 eruptions of the volcano have essentially the same mineralogy and chemistry. Data suggest that chemical composition changed little over the 0.3 m.y. sample period. Modally, plagioclase is the dominant phenocryst, followed by amphibole, clinopyroxene and minor phases including anhydrite. Plagioclase phenocrysts show complex zoning: the anorthite-rich zones are probably the result of changing volatile P on the magma and may reflect the changes in the volcano's magma reservoir in response to repetitive, explosive eruptive activity.-R.E.S.

Nucla circulating atmospheric fluidized bed demonstration project. Final report

Energy Technology Data Exchange (ETDEWEB)

1991-10-01

Colorado-Ute Electric Association began a study to evaluate options for upgrading and extending the life of its Nucla power station in 1982. Located in southwestern Colorado near the town of Nucla, this station was commissioned in 1959 with a local bituminous coal as its design fuel for three identical stoker-fired units, each rated at 12.6 MW(e). Poor station efficiency, high fuel costs, and spiraling boiler maintenance costs forced the Nucla Station into low priority in the CUEA dispatch order as early as 1981. Among the options CUEA considered was to serve as a host utility to demonstrate Atmospheric Fluidized Bed Combustion (AFBC) technology. The anticipated environmental benefits and apparent attractive economics of a circulating AFBC led to Colorado-Ute`s decision to proceed with the design and construction of a demonstration project in 1984 at the Nucla facility.

Evolutionary novelty versus exaptation: oral kinematics in feeding versus climbing in the waterfall-climbing Hawaiian Goby Sicyopterus stimpsoni.

Directory of Open Access Journals (Sweden)

Joshua A Cullen

Full Text Available Species exposed to extreme environments often exhibit distinctive traits that help meet the demands of such habitats. Such traits could evolve independently, but under intense selective pressures of extreme environments some existing structures or behaviors might be coopted to meet specialized demands, evolving via the process of exaptation. We evaluated the potential for exaptation to have operated in the evolution of novel behaviors of the waterfall-climbing gobiid fish genus Sicyopterus. These fish use an "inching" behavior to climb waterfalls, in which an oral sucker is cyclically protruded and attached to the climbing surface. They also exhibit a distinctive feeding behavior, in which the premaxilla is cyclically protruded to scrape diatoms from the substrate. Given the similarity of these patterns, we hypothesized that one might have been coopted from the other. To evaluate this, we filmed climbing and feeding in Sicyopterus stimpsoni from Hawai'i, and measured oral kinematics for two comparisons. First, we compared feeding kinematics of S. stimpsoni with those for two suction feeding gobiids (Awaous guamensis and Lentipes concolor, assessing what novel jaw movements were required for algal grazing. Second, we quantified the similarity of oral kinematics between feeding and climbing in S. stimpsoni, evaluating the potential for either to represent an exaptation from the other. Premaxillary movements showed the greatest differences between scraping and suction feeding taxa. Between feeding and climbing, overall profiles of oral kinematics matched closely for most variables in S. stimpsoni, with only a few showing significant differences in maximum values. Although current data cannot resolve whether oral movements for climbing were coopted from feeding, or feeding movements coopted from climbing, similarities between feeding and climbing kinematics in S. stimpsoni are consistent with evidence of exaptation, with modifications, between these

A portion of Yucca Mountain on and adjacent to the US Department of Energy's Nevada Test Site, Nye County, Nevada, is being considered as a possible location for a national high-level radioactive waste repository. The geologic and environmental characteristics of the site are being investigated to determine its suitability for further characterization. Goals of biotic studies were to identify species of concern, describe major floral and faunal associations, determine exposure levels of external background radiation, and assess possible impacts of characterization and operational activities. The species composition of dominant small mammals inhabiting major vegetation associations in 1984 varied little compared with results of similar surveys conducted in 1982 and 1983. Total captures were lower and reproduction was apparently curtailed. Merriam's kangaroo rat and the long tailed pocket mouse continued to be the most abundant species. Diversity of resident species did not differ significantly between the trapping lines. The composition and relative abundance of associated species was more variable. Western harvest mice were trapped for the first time, but pinyon mice, which were present in prior years, were not trapped. Five desert tortoises were observed during surveys of possible sites for repository surface facilities. 25 refs., 4 figs., 5 tabs

Asthma mortality rates have increased worldwide during the past several years despite the increased availability of new and effective medications. Few studies show reliable data from Latin American countries. To determine asthma mortality rates from 1984 to 1998 and to relate mortality to sales of asthma medications. We conducted a retrospective epidemiologic study in the total population of Uruguay. Data were obtained from the Department of Statistics of the Ministry of Public Health. Trends in mortality rates were analyzed using linear regression procedures. Spearman rank correlations were used to relate mortality rates to sales of asthma medications. The mean overall mortality rate was 5.10 per 100,000 during the period 1984 to 1998, (range 6.08 to 3.39) and showed a decreasing trend (P = 0.001). During the period 1995 to 1998, a more pronounced decrease was observed (mean mortality rate, 4.10 per 100,000). In the 5- to 34-year-old age group the mean mortality rate was 0.43 (range 0.65 to 0.13). Similarly, the mortality rate in this age group decreased particularly in the 1994 to 1998 period (mean 0.19; P = 0.005). Finally, the mortality rate was inversely correlated with sales of inhaled corticosteroids; for the overall mortality rate, p = -0.71, P = 0.003; for 5- to 34-year-old age group, p = -0.63, P = 0.01. Although mortality attributable to asthma seems to be decreasing, the overall mortality rate is still high compared with more economically developed countries. A more pronounced decrease in asthma mortality has been seen in the 5- to 34-year-old group. At present, Uruguay is a Latin American country with a low rate of asthma mortality. This is probably related to the use of new therapies to treat asthma.

Sr-90 and Cs-137 in freshwater fish were determined using radiochemical analysis. Three species of fish (Cyprinus carpio, Carassius auratus, and Hypomesus transpacificus nipponensis) were collected during the fishing season from eight sampling locations. Only the edible part was used in case of larger sized fish, and the whole part was used in case of smaller ones. Each sample was weighed and placed in a stainless steel pan or a porcelain dish. After carbonized, the sample was ashed in an electric muffle furnace. The maximum value of Sr-90 was 96 +- 1.7 pCi/kg in Cyprinus carpio collected from Akita in July 1984; and that of Cs-137 was 11 +- 0.7 pCi/kg in Carassius auratus from Fukui in December 1984.

All company-reported Working Level Months (WLM) data for 1967-1982 have been abstracted, keyed, and edited. For earlier years, the data base of working level measurements obtained from state agencies is also completed. Further follow-up of the cohort has been accomplished through the Social Security Administration and the National Death Index. Death certificates have been requested for 75 deceased cohort members. For feasibility evaluation of a prospective cohort study of miners with first underground experience after 1970, refinements of previous projections of available subjects have been made. An estimated 10,447 persons are available but with low mean cumlative exposures. Grants Clinic information for these miners has not yet been collected. Finally, planning for analysis has continued. To calculate comparison mortality rates, it is necessary to derive population estimates for New Mexico from 1957 through 1982. Counts have been developed for 1970 through 1982, and much of background work on the earlier years has been done. Alternative statistical approaches for data analysis are also being considered. 4 tables

Full Text Available Poultry meat production has doubled in past 40 years in the world, with the tendency of constant growth, and its production volume exceeds beef, but is behind pork production. For poultry meat production it is typical that its annual increase exceeds pork as well as beef production. The biggest producers of poultry meat are Asia, North and South America and Europe. The most significant category of poultry is meat of young chicken (broilers. Cobb, Ross and Hubbard broiler provenance are most common in Serbia. The objective of this investigation was to analyse poultry meat production volume in Serbia, observed during three six-years periods - A (1984-1989, B (1994-1999 i C (2004-2009. For data processing there were used the data obtained from Statistical Yearbooks of Serbia from 1984. to 2009. It was found out that average poultry meat production in period A was 108,33 ± 7,00 thousand tonnes, than it statistically significantly decreased and in period B it was 76,67±5,54 thousand tonnes, and finally in period C it was 72,17± 5,78 thousand tonnes.

Crustaceans from a tropical estuarine sand-mud flat, Pacific, Costa Rica, (1984-1988 revisited

Full Text Available The availability of data sets for time periods of more than a year is scarce for tropical environments. Advances in hardware and software speed-up the re-analysis of old data sets and facilitates the description of population oscillations. Using recent taxonomic literature and software we have updated and re-analized the information on crustacean diversity and population fluctuations from a set of cores collected at a mud-sand flat in the mid upper Gulf of Nicoya estuary, Pacific coast of Costa Rica (1984-1988. A total of 112 morphological species of macroinvertebrates was found, of which 29 were crustaceans. Taxonomic problems, maily with the peracarids, prevented the identification of a group of species. The abundance patterns of the crab Pinnixa valerii, the ostracod Cyprideis pacifica, and the cumacean Coricuma nicoyensis were analized with the Generalized Additive Models of the free software R. The models evidenced a variety of population oscillations during the sampling period. These oscillations probably included perturbations induced by external factors, like the strong red tide events of 1985. In additon, early on 1984 the populations might have been at an altered state due to the inpact of El Niño 1982-83. Thus, the oscillations observed during the study period departed from the expected seasonality (dry vs rainy pattern and are thus considered atypical for this tropical estuarine tidal-flat. Crustacean diversity and population peaks were within the range of examples found in worldwide literature. However, abundances of the cumacean C. nicoyensis, an endemic species, are the highest reported for a tropical estuary. Comparative data from tropical tidal flat crustaceans continues to be scarce. Crustaceans (total vs groups had population changes in response to the deployment of predator exclusion cages during the dry and rainy seasons of 1985. Temporal and spatial patchiness characterized the abundances of P. valeri, C. pacifica and C

The biomass with which this report is concerned includes aquatic plants, which can be converted into liquid fuels and chemicals; organic wastes (crop residues as well as animal and municipal wastes), from which biogas can be produced via anerobic digestion; and organic or inorganic waste streams, from which hydrogen can be produced by photobiological processes. The Biomass Program Office supports research in three areas which, although distinct, all use living organisms to create the desired products. The Aquatic Species Program (ASP) supports research on organisms that are themselves processed into the final products, while the Anaerobic Digestion (ADP) and Photo/Biological Hydrogen Program (P/BHP) deals with organisms that transform waste streams into energy products. The P/BHP is also investigating systems using water as a feedstock and cell-free systems which do not utilize living organisms. This report summarizes the progress and research accomplishments of the SERI Biomass Program during FY 1982.

Identification of "ever-cropped" land (1984-2010) using Landsat annual maximum NDVI image composites: Southwestern Kansas case study.

Science.gov (United States)

Maxwell, Susan K; Sylvester, Kenneth M

2012-06-01

A time series of 230 intra- and inter-annual Landsat Thematic Mapper images was used to identify land that was ever cropped during the years 1984 through 2010 for a five county region in southwestern Kansas. Annual maximum Normalized Difference Vegetation Index (NDVI) image composites (NDVI(ann-max)) were used to evaluate the inter-annual dynamics of cropped and non-cropped land. Three feature images were derived from the 27-year NDVI(ann-max) image time series and used in the classification: 1) maximum NDVI value that occurred over the entire 27 year time span (NDVI(max)), 2) standard deviation of the annual maximum NDVI values for all years (NDVI(sd)), and 3) standard deviation of the annual maximum NDVI values for years 1984-1986 (NDVI(sd84-86)) to improve Conservation Reserve Program land discrimination.Results of the classification were compared to three reference data sets: County-level USDA Census records (1982-2007) and two digital land cover maps (Kansas 2005 and USGS Trends Program maps (1986-2000)). Area of ever-cropped land for the five counties was on average 11.8 % higher than the area estimated from Census records. Overall agreement between the ever-cropped land map and the 2005 Kansas map was 91.9% and 97.2% for the Trends maps. Converting the intra-annual Landsat data set to a single annual maximum NDVI image composite considerably reduced the data set size, eliminated clouds and cloud-shadow affects, yet maintained information important for discriminating cropped land. Our results suggest that Landsat annual maximum NDVI image composites will be useful for characterizing land use and land cover change for many applications.

The history of gay bathhouses. 1984.

Science.gov (United States)

Bérubé, Allan

2003-01-01

Public policy regarding bathhouses has been criticized as being based on political expediency rather than on medical or social science. To affect that shortcoming, we include here a brief history of gay bathhouses. The history of the baths is rarely told, but whenever it is told it necessarily reflects the times in which it was written. For that reason, we include a history written in 1984, at the time that much of what was known about AIDS, routes of transmission and the role of the bathhouses was very much in flux. This history not only gives a context for the current discussion, but also allows the reader to see the history from that distant point in time. This paper was first published in December 1984 as an article in Coming Up!, a lesbian and gay community newspaper published monthly in San Francisco (California). It was later edited and reprinted in a book titled Policing Public Sex (1996). The version of the paper presented here is from the original 1984 article (pp. 15-19); several images appeared with the article that are not reproduced here. As with all the reprinted papers in this volume, no editorial changes were made to the paper and only minor typographical errors were corrected.

Solar-energy-system performance evaluation update: San Anselmo School, San Jose, California, April 1982-June 1982

Energy Technology Data Exchange (ETDEWEB)

Kendall, P.W.

1982-01-01

The solar collector array at the San Anselmo School is located on the roof of the structure, and consists of 3740 square feet of General Electric evacuated tube solar collectors, Model TC-100. Performance of the array during the three-month period was very similar to the overall performance during the previous reporting periods. During the three-month period from April 1982 through June 1982, the solar system at the San Anselmo School performed below expectations despite continued attempts to alleviate several long-standing system problems. Space heating performance appears to be meeting design goals; however, this load was trivial during the three-month period. The retrofitted solar system was designed to provide 70% of the space heating load and 72% of the space cooling load at this 34,000-square-foot brick structure. In all of the previous months of evaluation, the design values of 70% and above have not been achieved for the system as a whole, although one subsystem did achieve high solar contributions during periods of lower building loads, specifically the space heating subsystem. Solar contribution during the three-month period of April 1982 through June 1982 averaged 19% of the total load of 117.4 million Btu, and was, at best, equal to previous performance. Space heating loads were small, and the space cooling load was relatively high over the test period. The solar savings ratio was 14%. The system performance factor is a measure of the equivalent fossil fuel consumption at the site (with operating energy multiplied by 3.33 times to simulate fossil fuel use at the power plant) relative to the actual load, and was 0.15. This value is 0.03 points less than the previous year's value of 0.18. Solar System Coefficient of Performance (COP) increased to 11.0 vs. the previous year's value of 7.6. Apparently, the efficiency of energy transfer in the system has improved, although performance was not really any better.

2000-01-01

The article describes the evolution of Spain's nuclear power plants since 1982, the year in which the journal of the Spanish Nuclear Society first appeared, underlining those events that have had a special impact on this evolution at national and international level. At present, there are 9 nuclear groups operating in the country, of the total 17 that were at different stages of their life cycle at that time. This reduction in the number of groups that finally managed to initiated and indefinitely continue their operating lifetime contrasts with the growth of electricity consumption over the period, which has practically doubled. During these 18 years have been profound transformations in the social, economic and political context of Spain, both in general and in the Electricity Industry in particular. Nevertheless, there are now reasons, old new, to feel confident as regards the future of this energy source. (Author)

Atmospheric tritium 1968-1984. Tritium Laboratory data report No. 14

International Nuclear Information System (INIS)

Oestlund, H.G.; Mason, A.S.

1985-04-01

Tritium in the form of water, HTO, from the atmospheric testing of nuclear devices in the 60s has now mainly disappeared from the atmosphere and entered the ocean. The additions of such tritium from Chinese and French tests in the 70s were observed but did not make a big impression on the diminishing inventory of atmospheric HTO. Tritium in elemental form, HT, went through a maximum in the mid 70s, apparently primarily as a results of some underground testing of large nuclear devices and releases from civilian and military nuclear industry. The mid 70s maximum was 1.3 kg of tritium in this form, and in 1984 0.5 kg remain. The disappearance is slower than the decay rate of tritium, so sources must still have been present during this time. The global distribution shows, not unexpectedly, smaller inventory in the Southern Hemisphere across the equator and thus southward transport of HT. The chemical lifetime of hydrogen gas in the atmosphere, assuming the elemental tritium being in the form of HT, not T 2 , has been estimated between 6 and 10 years. It is to be expected that increasing activity of nuclear fuel reprocessing would in the near future again increase the global tritium gas inventory. Tritium in the form of light hydrocarbons, primarily methane, has also been measured, and in this form a quantity of 200 g of tritium resided in the global atmosphere 1956 to 1976. By 1982 it had decreased to 50 g. 25 refs., 5 figs., 11 tabs

Jayko, Angela S.; Wells, Ray E.; Digital Database by Givler, R. W.; Fenton, J.S.; Sinor, M.

2001-01-01

The Dixonville 7.5 minute quadrangle is situated near the edge of two major geologic and tectonic provinces the northernmost Klamath Mountains and the southeastern part of the Oregon Coast Ranges (Figure 1). Rocks of the Klamath Mountains province that lie within the study area include ultramafic, mafic, intermediate and siliceous igneous types (Diller, 1898, Ramp, 1972, Ryberg, 1984). Similar rock associations that lie to the southwest yield Late Jurassic and earliest Cretaceous radiometric ages (Dott, 1965, Saleeby, et al., 1982, Hotz, 1971, Harper and Wright, 1984). These rocks, which are part of the Western Klamath terrane (Western Jurassic belt of (Irwin, 1964), are considered to have formed within an extensive volcanic arc and rifted arc complex (Harper and Wright, 1984) that lay along western North America during the Late Jurassic (Garcia, 1979, Garcia, 1982, Saleeby, et al., 1982, Ryberg, 1984). Imbricate thrust faulting and collapse of the arc during the Nevadan orogeny, which ranged in age between about 150 to 145 Ma in the Klamath region (Coleman, 1972, Saleeby, et al., 1982, Harper and Wright, 1984) was syntectonic with, or closely followed by deposition of the volcano-lithic clastic rocks of the Myrtle Group. The Myrtle Group consists of Upper Jurassic and Lower to middle Cretaceous turbidity and mass flow deposits considered to be either arc basin and/or post-orogenic flysh basins that were syntectonic with the waning phases of arc collapse (Imlay et al., 1959, Ryberg, 1984, Garcia, 1982, Roure.and Blanchet, 1983). The intermediate and mafic igneous rocks of the Rogue arc and the pre-Nevadan sedimentary cover (the Galice Formation, (Garcia, 1979) are intruded by siliceous and intermediate plutonic rocks principally of quartz diorite and granodiorite composition (Dott, 1965, Saleeby, et al., 1982, Garcia, 1982, Harper and Wright, 1984). The plutonic rocks are locally tectonized into amphibolite, gneiss, banded gneiss and augen gneiss. Similar

Full Text Available Tourism corresponds to an economic modality, which is related to the natural, geographic, cultural, historical and geological characteristics of a place, being this activity of great importance for the development and exploration of a certain region. In this context, the region of Ipoema, district of Itabira (MG, stands out for your natural attractions such as waterfalls and overlook, which attract tourists to the locality, as well as the Museum of Tropeiro, which displaying part of the history of Brazil. The objective of this work was to characterize the lithotypes and geological outcrops in the Morro Redondo region and the Alta and Patrocínio Amaro waterfalls, located in the district of Ipoema, Itabira/MG, identifying the potential of natural attractions for the development of different tourist modalities. Thus, quartzite rocks were observed in the region, with granulation ranging from thin to midsize, characterized by well developed, locally corrugated foliation planes, which can be correlated to the Sopa-Brumadinho Formation, basal sequence of the Espinhaço Supergroup. In general, the region has potential for the ecotourism development, adventure tourism and cultural tourism. Although the geology of the region does not favor the geotourism development, this should be considered for the tourist activity planning, since the weathering of quartzite rocks originates sandy soils that need adequate management and protection, thus avoiding the degradation of these areas.

Uranium in Canada: 1984 assessment of supply and requirements

International Nuclear Information System (INIS)

1985-09-01

The success of uranium exploration efforts in Canada has continued, resulting in an overall increase in domestic uranium resource estimates for the principal resource categories. In 1984, Canada's five primary uranium producers employed some 5,800 people at their mining and milling operations, and produced concentrates containing some 11 170 tU. In 1984 the resource estimates were (in tonnes U recoverable): measured - 54 000; indicated - 233 000; inferred - 264 000. Canada's projected annual primary uranium production capability will stabilize at some 12 000 tU through the remainder of the 1980s. Should market conditions warrant, additional production centres could be developed to raise production capability to a level of 15 000 tU by the latter half of the 1990s. Prognosticated resources exploitable at uranium prices of $300/kg U or less are estimated to amount to 292 000 tU. Speculative resources of interest at prices of $300/kg U or less, in areas assessed during 1984, are thought to total approximately one million tU. Uranium exploration expenditures in Canada in 1983 and 1984 were an estimated $41 and $35 million, respectively. Exploration drilling and surface development drilling in 1983 and 1984 were reported to be 153 000 m and 197 000 m, respectively, some 85 per cent of which was in Saskatchewan. Canada's known uranium resources, recoverable at uranium prices of $150/kg U or less, are more than sufficient to meet the 30-year fuelling requirements of those reactors in Canada that are either in operation now or committed or expected to be in-service by 1995. Over the longer term, there is significant potential for discovering additional uranium resources in Canada

A hearing on S. 2846, which would amend the Nuclear Waste Policy Act of 1982 to authorize appropriations, reduces funding from $466.8 million in fiscal year 1984 to $460 million in fiscal year 1985. It also authorizes allocations. Responses to the bill noted its effect on state and federal relations and limitations on the scope of state participation. Testimony focused on the subject of States rights to reject a nuclear waste depository and other adverse effects. DOE and the nuclear industry oppose the legislation. Spokesmen for Texas felt that States rights would not suffer, but that the legislation would not be of help

A new 50-MHz Doppler radar with a mini-computer for real-time data processing and radar control was installed at Syowa Station, Antarctica in February 1982. Severe geomagnetic disturbances occurred at about 00 h UT, 14 July 1982. Then the magnetic H component decrease of about 4200 nT was observed at Syowa Station, and that of about 630 nT was observed at Kakioka Magnetic Observatory in the midlatitude. 50-MHz backscatter echoes were received on 13 - 14 July 1982 during a substorm growth phase, so the rough estimates of the Doppler velocity during this period were obtained. In this paper the Doppler spectra are discussed on the following three stages: SSC onset, substorm main phase and recovery phase. On the hypothesis of spatially homogeneous plasma flow, we determined a large-scale electric field by combining the drift velocities along the radar beams. It appeared that the E region electric field was larger than 30 mV/m in the main phase of this substorm. (author)

Contraceptive sterilization among Canadians, 1984-1995

Directory of Open Access Journals (Sweden)

Vijaya Krishnan

Full Text Available Prior to early 1970s, traditional methods were the principal means of controlling the number and spacing of births. Today, an estimated 57 per cent of the world’s married women use contraceptives and half use modern methods such as medical sterilizations. Recent statistics suggest that Canada has the highest sterilization rate in the Western world. This paper presents findings of research examining sterilization trends in Canada with respect to changing patterns in the use of modern contraceptives, using data from the 1984 Canadian Fertility Survey (CFS and the 1995 General Social Survey (GSS. The main finding is that there is a decrease in the use of tubal ligation and an increase in the use of hysterectomy over the period 1984-1995. Less educated women are more likely to be in the forefront of modern methods of contraception.

We consider D-term inflation for small couplings of the inflaton to matter fields. Standard hybrid inflation then ends at a critical value of the inflaton field that exceeds the Planck mass. During the subsequent waterfall transition the inflaton continues its slow-roll motion, whereas the waterfall field rapidly grows by quantum fluctuations. Beyond the decoherence time, the waterfall field becomes classical and approaches a time-dependent minimum, which is determined by the value of the inflaton field and the self-interaction of the waterfall field. During the final stage of inflation, the effective inflaton potential is essentially quadratic, which leads to the standard predictions of chaotic inflation. The model illustrates how the decay of a false vacuum of GUT-scale energy density can end in a period of 'chaotic inflation'.

Full Text Available This article analyzes the speeches issued by La Vanguardia at the end of détente between the blocks, in the period from 1979 to 1984. From a historical context of the period, we proceed to content analysis, quantitative and qualitative, around two topics: disarmament and terrorism. In moments of high tension of the Cold War, of great historical and political relevance, but above all, time for a big ideological friction, the head’s attitude was characterized by rigor and weighting. The denouncement of the irresponsability of the blocks to attend policy strategies, the rearmament, European marginality and the terrorist threat, are the main concerns extracted from the study. | Este artículo analiza los discursos emitidos por La Vanguardia con motivo del fin de la distensión entre los bloques en el período que abarca desde 1979 hasta 1984. A partir de una contextualización histórica concreta, nos ocupamos del vaciado de prensa y análisis de contenido, cuantitativo y cualitativo, en torno a dos bloques temáticos: el desarme y el terrorismo. En unos años de máxima tensión de la Guerra Fría, de gran trascendencia histórica y política, pero sobre todo, de máxima fricción ideológica, la actitud de la cabecera catalana estuvo caracterizada por el rigor y la ponderación. La denuncia de la irresponsabilidad de los bloques por atender a estrategias políticas, junto con el rearme, la marginalidad europea y la amenaza terrorista, son las principales preocupaciones argumentales que surgen del estudio.

This paper analyzed the temporal variations of Cu in Jiaozhou Bay during 1982-1986. Results showed that Cu contents in study years were 0.15-5.31 μg L-1, 0.77-20.60 μg L-1, 0.11-4.00 μg L-1, 0.10-0.43 μg L-1 and 0.18-0.77 μg L-1, respectively. The Cu pollution level in this bay was moderate during 1982-1983, yet for temporal variations Cu contents in surface waters were showing decreasing trend. Cu contents in spring, summer and autumn were 0.11-20.60 μg L-1, 0.10-4.86 μg L-1 and 0.11-3.56 μg L-1, respectively. This bay was moderate pollution in spring in 1982-1983, while in other seasons in study years was still slight. These indicated that the temporal variations of Cu pollution in this bay should be taken in to account in decision-making of pollution control practice.

Part 1 covers efforts of direct assistance to the Department of Energy (DOE) and Nuclear Regulatory Commission (NRC) licensee facilities. Part 2 treats activities aimed at the security of information and computer systems. was Part 3 describes the broad development efforts essential to continuing improvements in the practice of safeguards. Although these projects are properly classified as developmental, they address recognized problems that commonly occur in operating facilities. Finally, Part 4 covers international safeguards activities, including both support to the International Atomic Energy Agency and bilateral exchanges. Enrichment plant safeguards, especially those concerning the Gas Centrifuge Enrichment Plant, required a significant portion of our resources. These efforts are beginning to provide substantial returns on our investment in technology transfer, not only in raising the level of safeguards effectiveness but also in benefiting from field experiences in operating environments.

This report contains the final results of investigations concerning the caribou herd south of Ameralik fjord in the period 1982-1985. The purpose of the investigations was to get a background knowledge for evaluating the effects of the proposed hydropower project at Kangerluarsunnguaq/Buksefjord. The herd was estimated to number 2000-2500 individuals in November 1985 and seemed to be slightly increasing. During the investigations the proportion of younger individuals has increased. It is concluded that the herd most years is ''limited'' by snow conditions making a large part of the winter food unavailable. The hydropower project might influence the caribou during calving through construction activities. Furthermore, the transmission line could be expected to influence the use of different areas at different seasons, but it is not expected to exclude the animals from tho coastal areas. A suitable planning of construction activities in relation to season could relieve the effects. 24 refs.

As a distinctive feature of the ionosphere observed in 1982, it may be said that the ionospheric disturbances associated with outstanding solar flares occurred frequently, especially that the tendency was remarkable during the period from June to September 1982. First, the feature found is an abnormal increase in fsub(min) on ionograms observed during the period from 4 June to 19 July. Secondly, it contains ionospheric disturbances which appeared in the F-region associated with geomagnetic storms, in the period from 13 to 16 July, from 5 to 8 September and from 21 to 28 September, 1982. Variations in the aspect which ionospheric storms associated with these geomagnetic storms had assumed due to the magnitude of geomagnetic storms, the local time of their occurrence, and their passage were extensively investigated by utilizing data from not only the five Japanese ionospheric stations, but also available eastern Asia, Europe, and so on. The four ionospheric storms investigated had individual characteristics due to the difference among local times of appearance in main phase of geomagnetic storms related to ionospheric storms. The scale of the ionospheric storms associated with a giant geomagnetic storm on July 14 whose drop in horizontal component amounted to 630 nT in its maximum stage was smaller than that on August 4-5, 1972 (359 nT).

The article reports on achievements of various people, staff changes and position opportunities within the CERN organization and contains news updates on upcoming or past events. Some time ago, Wolfgang ('Pief') Panofsky, Director of SLAC since 1961 and one of the prime movers behind both the famous two-mile electron linac and the Laboratory itself, announced his intention to step down in 1984. Immediately a search began for a worthy successor. Carlo Rubbia, leader of the UA 1 experiment at CERN which last year discovered the W and Z particles, was named by the US science magazine 'Discover' as its 1983 'Scientist of the Year'. A CERN-ECFA Workshop to study the feasibility of hadron colliders which it might at some time in the future be possible to install in the LEP tunnel, is to be held at the University of Lausanne from 21-24 March. Fermilab will host the 1984 US Summer School on High Energy Particle Accelerators from 13-24 August - the fourth in this series of summer schools.The 1984 CERN School of Computing, the eighth in the biennial series, is being organized in collaboration with the Instituto Estudios Energeticos (Junta de Energia Nuclear, Madrid) and the Facultad de Informatica, Barcelona, and will be held from 9-22 September at Aiguablava, Spain. The 1984 Users' Meeting of the High Energy Discussion Group (HEDG) at Brookhaven on 29-31 March will include a Workshop on the possible physics from an improved Alternating Gradient Synchrotron.

One of the main objectives of CANMET's Energy Research program is to develop the technologies required to conserve and to increase the supply of liquid fossil fuels in Canada to bridge the gap that exists between domestic supply and demand (both internal demand and export opportunities). The Energy Research Laboratories (ERL) respond to this R D objective on matters related to the upgrading of oil sands; heavy oil and synthetic crude production; coal/bitumen coprocessing; and improved oil and gas domestic heating furnaces. Another major objective is to develop the technologies to burn fossil fuels, mainly coal, under environmentally acceptable conditions; ERL responds to this objective through research in the areas of coal combustion and gasification. This report summarizes the activities of ERL during the fiscal year 1984/85. A recent reorganization of the ERL is summarily described. The total expenses of ERL in 1984/85 were 169 persons/year, $6.375 million in salaries, $3.499 million in operating costs, $2.740 million in capital investments, and $10,000 million in contracts. Included in the report are listings of employees, patents, publications, technical committees, and contracts. 2 figs., 2 tabs.

1984-11-01

The program for the assessment of the geothermal energy potential of Atlantic Canada is now in its fifth year. Most of the work - the compilation of existing data, the acquisition of new data on an opportunity basis, and the interpretation of the amassed data base - has been substantially completed. In 1982 the program entered its final phase, that of generating new data at specific targets of interest, at considerably greater cost than earlier phases. In 1983 the various earth science projects were, with the exception of a small data-compilation continuation contract, all site- or area-specific. A test hole was drilled on the campus of the University of Prince Edward Island in Charlottetown, a magnetotelluric survey was conducted across P.E.I., and hydrological studies of two small sedimentary basins were undertaken, in New Brunswick and in Nova Scotia. This report summarizes the results obtained. Some work recently completed is also briefly discussed. 7 refs., 1 fig.

Uranium in Canada: 1982 assessment of supply and requirements

International Nuclear Information System (INIS)

1983-09-01

Estimates of Canada's uranium resources for 1982 remained essentially unchanged from those of 1980. However, the economic conditions facing the industry have changed greatly during the past few years as production costs continued to rise without corresponding increases in uranium prices. As a result, a smaller portion of Canada's uranium resources is of current economic interest. Total resources amount to 573 000 tonnes of uranium. Just over 10% of this uranium will be required domestically during the next 30 years to fuel the more than 15 000 megawatts of nuclear power capacity now operating or committed for operation in Canada by 1993. In 1982 seven uranium producers in Canada, directly employing 4800 people, produced concentrates containing 8075 tonnes of uranium. Based on currently committed expansion plans, Canada's projected annual production capability could grow to some 12 000 tonnes of uranium by 1986. Canadian producers shipped 7643 tonnes of uranium valued at some $838 millon in 1982. As of January 1, 1983, outstanding uranium export commitments amounted to 60 000 tonnes or roughly 10% of the total Canadian uranium resources mentioned above. Japan has been Canada's most important single customer in the past decade, receiving about 34% of Canada's total exports since 1972. Most of the remaining exports have gone to the European Economic Community (33%), other countries in Western Europe (18%), and the United States (15%). Substantial efforts in uranium exploration that have been continued, especially in northern Saskatchewan, where two-thirds of the $71 million total exploration expenditures of 1982 were incurred. This continued effort has led to the discovery of a number of important deposits over the past few years which could be developed if market conditions improve. It is estimated that total Canadian production capability could reach 15 000 tonnes of uranium annually by the mid-1990s

This report reviews the major activities and accomplishments of the Organic Research Section in 1984 and presents the 1985 work program. The three major areas of the Section's research work are non-metallic materials which includes applications and uses of plastics, petroleum products, coatings and elastomers; reactor waste management; and activity transport/decontamination of nuclear systems. In 1984, 50% of the Section's resources were used on studies in support of nuclear generation, 13% on reactor waste, and 37% on general activities and work in support of utilization, transmission and distribution, and thermal and hydraulic programs. About 60% of the section's work was supported by transfer and revenue funds as a result of urgent short-term work requirements which resulted in 68% of the work falling into the technical investigation, consulting and testing categories

Energy analysts present year-end 1982 estimates for world proved reserves, remaining recoverable resources, annual production rates, and cumulative production of the non-renewable convectional energy resources: coal, natural gas, crude oil, natural gas liquids, bitumens, shale oil, and uranium oxide. Life indices for world fossil fuels are also given for several annual growth rates. The world's proved and currently recoverable natural gas reserves amount to 2649-3250 trillion CF; the estimated total remaining recoverable is 6693-7462 TCF. In 1982, 54 TCF of gas was produced for a cumulative production of 1320 TCF (not counting vented or flared gas)

Recursive stochastic effects in valley hybrid inflation

Science.gov (United States)

Levasseur, Laurence Perreault; Vennin, Vincent; Brandenberger, Robert

2013-10-01

Hybrid inflation is a two-field model where inflation ends because of a tachyonic instability, the duration of which is determined by stochastic effects and has important observational implications. Making use of the recursive approach to the stochastic formalism presented in [L. P. Levasseur, preceding article, Phys. Rev. D 88, 083537 (2013)], these effects are consistently computed. Through an analysis of backreaction, this method is shown to converge in the valley but points toward an (expected) instability in the waterfall. It is further shown that the quasistationarity of the auxiliary field distribution breaks down in the case of a short-lived waterfall. We find that the typical dispersion of the waterfall field at the critical point is then diminished, thus increasing the duration of the waterfall phase and jeopardizing the possibility of a short transition. Finally, we find that stochastic effects worsen the blue tilt of the curvature perturbations by an O(1) factor when compared with the usual slow-roll contribution.

The article reports on achievements of various people, staff changes and position opportunities within the CERN organization and contains news updates on upcoming or past events. Some time ago, Wolfgang ('Pief') Panofsky, Director of SLAC since 1961 and one of the prime movers behind both the famous two-mile electron linac and the Laboratory itself, announced his intention to step down in 1984. Immediately a search began for a worthy successor. Carlo Rubbia, leader of the UA 1 experiment at CERN which last year discovered the W and Z particles, was named by the US science magazine 'Discover' as its 1983 'Scientist of the Year'. A CERN-ECFA Workshop to study the feasibility of hadron colliders which it might at some time in the future be possible to install in the LEP tunnel, is to be held at the University of Lausanne from 21-24 March. Fermilab will host the 1984 US Summer School on High Energy Particle Accelerators from 13-24 August - the fourth in this series of summer schools.The 1984 CERN School of Computing, the eighth in the biennial series, is being organized in collaboration with the Instituto Estudios Energeticos (Junta de Energia Nuclear, Madrid) and the Facultad de Informatica, Barcelona, and will be held from 9-22 September at Aiguablava, Spain.

Shutdowns/scrams at BWRs reported under new 1984 LER rule

International Nuclear Information System (INIS)

Mays, G.T.

1985-01-01

Operating experience data from nuclear power plants are essential for safety and reliability analyses. The Licensee Event Reports (LERs), submitted to the NRC by nuclear power plant utilities, contain much of this data. One of the significant aspects of the new LER rule includes the requirement to report all plant shutdowns whereas prior to 1984, not all shutdowns were reported as LERs. This paper reviews the shutdowns and scrams occurring during the first six months of 1984 at BWRs as reported under the new LER rule. The review focused on systems involved, causes, and personnel interactions

Identification of canine coronary resistance and intramyocardial compliance on the basis of the waterfall model.

Science.gov (United States)

Burattini, R; Sipkema, P; van Huis, G A; Westerhof, N

1985-01-01

This study was performed to elucidate the effects of cardiac contraction on coronary pressure-flow relations. On the basis of the waterfall mechanism, a lumped model of the coronary arterial system is presented consisting of a proximal (epicardial) compliance, a coronary resistance, and an intramyocardial compliance. A "back"-pressure, assumed to be proportional (constant k) to left ventricular pressure, impedes flow. From steady-state measurements of circumflex coronary artery flow and inflow pressure, together with left ventricular pressure, the values of the three model parameters and the constant k have been estimated. In the control condition proximal compliance is found to be 1.7 X 10(-12) m4s2kg-1, intramyocardial compliance 110 X 10(-12)m4s2kg-1, and resistance 7.5 X 10(9) kgm-4s-1. The proportionality constant k is close to unity. Effects of changes in left ventricular pressure and inflow pressure and the effect of vasoactive drugs on the parameters are also investigated. Changes in coronary resistance are always opposite to changes in intramyocardial compliance. Sensitivity analysis showed that epicardial compliance plays its major role during isovolumic contraction and relaxation; resistance plays a role throughout the cardiac cycle but is more important in diastole than in systole, whereas intramyocardial compliance plays a role in systole and in early diastole.

Grain fracture model and its application to strength evaluation in engineering ceramics

Science.gov (United States)

Hoshide, Toshihiko

1993-02-01

A new model of cracking process in ceramics is developed assuming the fracture of the grain just ahead of a flaw, such as a crack or a notch, during the loading process, prior to the final unstable fracture. Based on the grain fracture model, a simulation was carried out to explain the anomalous behavior of small flaws and the notch width effect, which were reported by Evans and Langdon (1976) and Hoshide et al. (1984) and by Bertolotti (1973) and Pabst et al. (1982), respectively. It is shown that the analytical relations of the new model can explain the experimental results for both situations.

Major Brazilian gold deposits - 1982 to 1999

Science.gov (United States)

Thorman, Charles H.; DeWitt, Ed; Maron, Marcos A.; Ladeira, Eduardo A.

2001-07-01

Brazil has been a major but intermittent producer of gold since its discovery in 1500. Brazil led the world in gold production during the 18th and early 19th centuries. From the late 19th century to the late 20th century, total mining company and garimpeiro production was small and relatively constant at about 5 to 8 t/year. The discovery of alluvial deposits in the Amazon by garimpeiros in the 1970s and the opening of eight mines by mining companies from 1983 to 1990 fueled a major boom in Brazil's gold production, exceeding 100 t/year in 1988 and 1989. However, garimpeiro alluvial production decreased rapidly in the 1990s, to about 10 t/year by 1999. Company production increased about tenfold from about 4 t/year in 1982 to 40 t in 1992. Production from 1992 to the present remained relatively stable, even though several mines were closed or were in the process of closing and no new major mines were put into production during that period. Based on their production history from 1982-1999, 17 gold mines are ranked as major (>20 t) and minor (3-8 t) mines. From 1982-1999, deposits hosted in Archean rocks produced 66% of the gold in Brazil, whereas deposits in Paleoproterozoic and Neoproterozoic rocks accounted for 19% and 15%, respectively. Deposits in metamorphosed sedimentary rocks, especially carbonate-rich rocks and carbonate iron-formation, yielded the great bulk of the gold. Deposits in igneous rocks were of much less importance. The Archean and Paleoproterozoic terranes of Brazil largely lack base-metal-rich volcanogenic massive sulfide deposits, porphyry deposits, and polymetallic veins and sedimentary exhalative deposits. An exception to this is in the Carajás Mineral Province.

Research progress is reported on developing Ocean Thermal Energy Conversion (OTEC) systems that will provide synthetic fuels (e.g., methanol), energy-intensive products such as ammonia (for fertilizers and chemicals), and aluminum. The work also includes assessment and design concepts for hybrid plants, such as geothermal-OTEC (GEOTEC) plants. Another effort that began in the spring of 1982 is a technical advisory role to DOE with respect to their management of the conceptual design activity of the two industry teams that are designing offshore OTEC pilot plants that could deliver power to Oahu, Hawaii. In addition, a program is underway in which tests of a different kind of ocean-energy device, a turbine that is air-driven as a result of wave action in a chamber, are being planned. This Quarterly Report summarizes the work on the various tasks as of 31 December 1982.

Understanding the interaction between natural and socio-economic factors that determine fire regime is essential to make accurate projections and impact assessments. However, this requires having accurate historical, systematic, homogeneous and spatially explicit information on fire occurrence. Fire databases usually have serious limitations in this regard; therefore other sources of information, such as remote sensing, have emerged as alternatives to generate optimal fire maps on various spatial and temporal scales. Several national and international projects work in order to generate information to study the factors that determine the current fire regime and its future evolution. This work is included in the framework of the project "Forest fires under climate, social and economic Changes in Europe, the Mediterranean and other fire-affected areas of the World" (FUME http://www.fumeproject.eu), which aims to study the changes and factors related to fire regimes through time to determine the potential impacts on vegetation in Mediterranean regions and concrete steps to address future risk scenarios. We analyzed the changes in the fire regime in Madrid region (Spain) in the past three decades (1984-2010) and its relation to land use changes. We identified and mapped fires that have occurred in the region during those years using Landsat satellite images by combining digital techniques and visual analysis. The results show a clear cyclical behaviour of the fire, with years of high incidence (as 1985, 2000 and 2003, highlighted by the number of fires and the area concerned, over 2000 ha) followed by another with a clear occurrence decrease. At the same time, we analyzed the land use changes that have occurred in Madrid region between the early 80s and mid-2000s using as reference the CORINE Land-cover maps (1990, 2000 and 2006) and the Vegetation and Land Use map of the Community of Madrid, 1982. We studied the relationship between fire regimes and observed land

Pärna, Kersti; Põld, Mariliis; Ringmets, Inge

2017-07-25

Smoking surveys among physicians have proved useful in highlighting the importance of physicians as healthy life style exemplars and role models in tobacco control and smoking cessation. The aim of this study was to give an overview of smoking behaviour among Estonian physicians from 1982 to 2014. Three cross-sectional postal surveys using a self-administered questionnaire were carried out among all practising physicians in Estonia. The number of physicians participating in this study was 3786 in 1982, 2735 in 2002, and 2902 in 2014. Data analysis involved calculating the age-standardized prevalences of smoking, prevalences of smoking by age group and mean age of smoking initiation. A non-parametric test for trend was used to assess significant changes in smoking over time. Age-standardized prevalence of current smoking among men was 39.7% in 1982, 20.9% in 2002, and 14.3% in 2014 and among women 12.2%, 8.0%, and 5.2%, respectively (p smoking among men and women was in age groups under 35 (from 55.2% to 16.7% and from 16.7% to 2.8%, respectively) and 35-44 (from 47.1% to 8.3% and from 19.5% to 5.1%, respectively) (p smoking initiation decreased from 20.4 to 19.3 among men and from 24.5 to 20.4 among women over the study period. In 1982-2014, smoking prevalence among Estonian physicians declined substantially. This may influence the willingness of society to recognize the health consequences of smoking which could give a support to the decline of the smoking epidemic in the country. Differences between smoking among male and female physicians persisted over the study period, but mean age of smoking initiation decreased. A further decline in smoking among Estonian physicians should be encouraged by special efforts targeted at physicians.

Strontium-90 and cesium-137 in sea sediments (from May 1984 to Sep 1984)

International Nuclear Information System (INIS)

1984-01-01

Strontium-90 and cesium-137 monitoring results are presented for sea sediment samples of 12 sampling points located all over Japan from Tomari, Hokkaido to Kinnakagusuku Bay, Okinawa. The samples were collected by considering of enough sea water depth, no significant sedimental movement and sediment characteristics, and by employing a conventional sampling device. Approximately 4 kg-wet sample was dried and was passed through a 20 cm mesh sieve. After adding of strontium and cesium carriers, strontium-90 and cesium-137 were leached with a hot hydrochloric acid solution. The leachate was treated by ion exchange and coprecipitation to concentrate and isolate strontium-90 or cesium-137. Radiation counting was carried out by employing a low background beta counter usually for 60 minutes for the samples of strontium carbonate or cesium chloroplatinate. Determined strontium-90 contents in sea sediment were distributed from 0 +- 2.7 pCi/kg-dry (Mutsu Bay, Aomori, Yamaguchi Bay, Yamaguchi) to 14 +- 3.2 pCi/kg-dry (Mutsu Bay), and those of cesium-137 were from 9 +- 3.5 pCi/kg-dry (Mutsu Bay) to 250 +- 9 pCi/kg-dry (Off-Niigata Port, Niigata). Local variation of the contents of these radionuclides was very large, and for seasonal variation, it was also found large for the both nuclides content in the Mutsu Bay samples of May, 1984 and August 1984, as for strontium-90, 0 +- 2.7 pCi/kg and 14 +- 3.2 pCi/kg, for cesium-137, 9 +- 3.5 pCi/kg and 200 +- 8 pCi/kg, respectively.

Province, S.G.; Sherwood, P.B.

1984-11-01

The City of El Centro was awarded a contract in late 1978 to cost share the development of a low to moderate temperature geothermal resource in the City. The resource would be utilized to heat, cool and provide hot water to the nearby Community Center. In December 1981, Thermal 1 (injector) was drilled to 3970 feet. In January 1982, Thermal 2 (producer) was drilled to 8510 feet. Before testing began, fill migrated into both wells. Both wells were cleaned out. A pump was installed in the producer, but migration of fill again into the injector precluded injection of produced fluid. A short term production test was undertaken and results analyzed. Based upon the analysis, DOE decided that the well was not useful for commercial production due to a low flow rate, the potential problems of continued sanding and gasing, and the requirement to lower the pump setting depth and the associated costs of pumping. There was no commercial user found to take over the wells. Therefore, the wells were plugged and abandoned. The site was restored to its original condition.

Measurements of mesospheric water vapor in 1984 and 1985 - Results and implications for middle atmospheric transport

Science.gov (United States)

Bevilacqua, Richard M.; Schwartz, Philip R.; Wilson, William J.

1987-01-01

The detailed results of ground-based mesospheric water vapor measurements obtained by microwave spectroscopy at the Jet Propulsion Laboratory (JPL) from December 1984 to April 1985 (JPL 1984/85), and an overview of results obtained the previous year from April to June 1984 are presented. The JPL 1984/85 spectral data appeared to contain an instrumental baseline curvature which was bracketed and removed. In general, the JPL 1984/85 results are in good agreement with those of previous measurements. They indicate water vapor mixing ratios between 6 and 8 ppmv at 60 or 65 km and falling off steeply with height above this point to values of less than 2 ppmv at 80 km. In addition, there is a large amount of day-to-day variability indicated in the data. A major result of the study is that it is found that both the observed vertical gradient of water vapor mixing ratio and its seasonal variation are consistent with the hypothesis that vertical transport time scales are smaller, perhaps by an order of magnitude, than values currently used in both one- and two-dimensional photochemical/dynamical models.

Offsite environmental radiation dose equivalents based on Hanford operations are compared for the years 1977 through 1981 to those calculated for 1982. The comparison revealed a downward trend in calculated offsite doses over the period 1977 through 1982, due primarily to reported reduced effluent releases, changes in effluent reporting methods, and increased Columbia River flow over this period. The calculated doses verify the surveillance program findings that potential offsite radiation doses due to Hanford Operations are small and well below our ability to detect in the environment. 11 references, 23 tables

The 1984 eclipse of the symbiotic binary SY Muscae

Science.gov (United States)

Kenyon, S. J.; Michalitisianos, A. G.; Lutz, J. H.; Kafatos, M.

1985-01-01

Data from IUE spectra obtained with the 10 x 20-arcsec aperture on May 13, 1984, and optical spectrophotometry obtained with an SIT vidicon on the 1.5-m telescope at CTIO on April 29-May 1, 1984, are reported for the symbiotic binary SY Mus. The data are found to be consistent with a model of a red-giant secondary of 60 solar radii which completely eclipses the hot primary every 627 d but only partially eclipses the 75-solar-radius He(+) region surrounding the primary. The distance to SY Mus is estimated as 1.3 kpc. It is suggested that the large Balmer decrement in eclipse, with (H-alpha)/(H-beta) = 8.3 and (H-beta)/(H-gamma) = 1.5, is associated with an electron density of about 10 to the 10th/cu cm.

Environmental radioactivity in Canada - 1982

International Nuclear Information System (INIS)

Tracey, B.L.

1984-01-01

The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. Special investigations were carried out during 1982 on metabolism of natural radionuclides and on the accumulation of radon in energy-efficient homes. The pre-operational phase of the monitoring program at the Point Lepreau Nuclear Generating Station was completed. Dose commitments have been estimated for the ongoing natural radioactivity, fallout and reactor studies. All measurements made during the year are below the limits recommended by the International Commission on Radiological Protection

The Agency's Technical Co-operation activities in 1984. Report by the Director General

International Nuclear Information System (INIS)

1985-08-01

The year 1984 can be described as one during which efforts were made to increase momentum in the development co-operation between the Agency and its Member States while continuing to improve the quality of the technical assistance rendered. For the first time, the adjusted programme exceeded $50 million. During the year, changes were introduced in the administration of the programme in line with recommendations endorsed by the Board in 1983 at the end of its first technical co-operation policy review. In 1984, when the new technical co-operation policies were applied, there were three principal aims. First, the flow of Technical Assistance and Co-operation Fund resources was to be improved; by decreasing accumulated unobligated balances, an optimum level of resource utilization was to be attained by 1986. Second, procedures for the procurement of goods and services were to be streamlined in order to permit substantial increases in programme delivery. Third, systematic project evaluation was to lead to a number of specific actions that would increase the effectiveness of the Agency's development assistance. With regard to the first aim, implementation increased by 44% over the 1983 level, passing the $30 million mark in October and reaching $36.6 million by the end of the year. Of this amount, $31.8 million related to the implementation of activities programmed for 1984. Therefore, an increase in total resources of only 4% was accompanied by an increase in current-year implementation of 34%. As a result, the upward trend in the unobligated balance was checked, and earmarkings against the TACF actually decreased. The implementation rate against the TACF rose from 58% in 1983 to 65% in 1984, reaching the level that had been set as a target. If this performance can be maintained in 1985, it will be possible to reach the optimum level of TACF resource utilization one year earlier than originally expected. As regards the second aim, streamlined procedures introduced in

Schiefelbein, G.F.; Stevens, D.J.; Gerber, M.A.

1985-01-01

The objective of the program is to generate scientific data and conversion process information that will lead to establishment of cost-effective process for converting biomass resources into clean fuels. The goal of the program is to develop the data base for biomass thermal conversion by investigating the fundamental aspects of conversion technologies and by exploring those parameters that are critical to the conversion processes. The research activities can be divided into: (1) gasification technology; (2) liquid fuels technology; (3) direct combustion technology; and (4) program support activities. These activities are described in detail in this report. Outstanding accomplishments during fiscal year 1984 include: (1) successful operation of 3-MW combustor/gas turbine system; (2) successful extended term operation of an indirectly heated, dual bed gasifier for producing medium-Btu gas; (3) determination that oxygen requirements for medium-Btu gasification of biomass in a pressurized, fluidized bed gasifier are low; (4) established interdependence of temperature and residence times on biomass pyrolysis oil yields; and (5) determination of preliminary technical feasibility of thermally gasifying high moisture biomass feedstocks. A bibliography of 1984 publications is included. 26 figs., 1 tab.

Transportation systems to support the Nuclear Waste Policy Act of 1982

International Nuclear Information System (INIS)

Wilmot, E.L.; Philpott, R.E.

1985-01-01

Late in 1982, the United States Congress enacted legislation for the disposal of spent nuclear fuel and high-level waste. The policy, embodied in Public Law 97-425 and referred to as the Nuclear Waste Policy Act of 1982 (NWPA), mandates that the Department of Energy (DOE) be responsible for the transport of commercial spent fuel and defense high-level waste from their points of origin to facilities constructed under provisions of the NWPA. It is the purpose of this paper to describe the preliminary transportation policies and plans developed by the Office of Civilian Radioactive Waste Management (OCRWM), within the DOE, to respond to the NWPA mandate

Annual report, 1982

International Nuclear Information System (INIS)

1982-11-01

Several major upgrading projects were completed during 1982. The original accelerator tubes were replaced with a set of Dowlish spiral inclined field tubes, and the original belt charging system was replaced with a pair of NEC Pelletron charging chains. This has upgraded voltage capacity by at least 1.5 MV and made a significant improvement in voltage stability. A new VAX-11/750 computer was installed, which will allow a more sophisticated approach to multi-parameter data acquisition and analysis. Use of the multiplicity filter to study gamma-ray transitions between high-lying members of bands continues, and will be helped with the voltage upgrading of the tandem and with the VAX. The polarized source, providing both p and d beams, allowed continuing studies of vector and tensor analysing powers. New research programmes in hydrogen depth profiling and studies of infrared absorption in solid hydrogen have begun

Evaluative studies in nuclear medicine research: positron computed tomography assessment. Final report, January 1, 1982-December 31, 1982

International Nuclear Information System (INIS)

Potchen, E.J.; Harris, G.I.; Gift, D.A.; Reinhard, D.K.; Siebert, J.E.

1983-02-01

Results are reported of the final phase of the study effort generally titled Evaluative Studies in Nuclear Medicine Research. The previous work is reviewed and extended to an assessment providing perspectives on medical applications of positron emission tomographic (PET) systems, their technological context, and the related economic and marketing environment. Methodologies developed and used in earlier phases of the study were continued, but specifically extended to include solicitation of opinion from commercial organizations deemed to be potential developers, manufacturers and marketers of PET systems. Several factors which influence the demand for clinical uses of PET are evaluated and discussed. The recent Federal funding of applied research with PET systems is found to be a necessary and encouraging event toward a determination that PET either is a powerful research tool limited to research, or whether it also presents major clinical utility. A comprehensive, updated bibliography of current literature related to the development, applications and economic considerations of PET technology is appended

Solar-terrestrial disturbances of June-September 1982, 4

International Nuclear Information System (INIS)

Kikuchi, Takashi; Sugiuchi, Hidetoshi; Ishimine, Tsuyoshi; Maeno, Hideo; Honma, Shigehisa

1986-01-01

This paper reports the solar flare and geomagnetic storm effects on the frequency of JJY signals received at Okinawa (f = 15 MHz) and Kokubunji (f = 5 and 8 MHz) during the period of June-September 1982. The increase in the electron density due to solar flares is deduced from the Doppler frequency deviation of 1 Hz as 2 x 10 15 electrons/m 2 below the reflection height. The result is in good agreement with the observation of the total electron content by the Faraday rotation measurement. On July 13, 1982, an abrupt increase of 0.8 Hz in frequency followed by a decrease of 0.6 Hz was observed in association with the huge storm sudden commencement. This fact indicates a successive transmission of westward electric field of 1.5 mV/m and eastward electric field of 1.1 mV/m from the outer magnetosphere to the low latitude ionosphere. It is shown that the decreases in Doppler frequency were associated with geomagnetic bays. The strength of the electric field (1.8 mV/m) derived from the Doppler frequency deviation is 20 % of that of the electric field which is required to produce ionospheric electric currents responsible for the geomagnetic field variation on the ground. The large amplitude Doppler frequency oscillations of period of 1 - 1.5 h were observed at Kokubunji and Okinawa with a delay time of 20 - 25 min during the geomagnetic storm on September 6, 1982. It is suggested that the large-scale TID (Traveling Ionospheric Disturbance) with a phase velocity of 600 m/s and a wavelength of 2000 km is produced at high latitudes and is propagated to low latitudes.

Environmental and Occupational Safety Division annual progress report for 1984

International Nuclear Information System (INIS)

1985-11-01

Over 950 radiation workers were monitored at ORNL for both internal and external exposure to ionizing radiation and radioactive materials in 1984, and no employee exceeded 50% of the applicable DOE dose limit. No internal exposure exceeded 10% of the maximum permissible organ burden, as determined by in-vivo gamma spectrometry. Dose readings from 5000 TLDs and 136,000 pocket meters were determined, and more than 5800 calibrations were performed on these devices. Approximately 82,000 radioassays were performed; among these were 1500 urinalyses and 3000 radiochemical analyses. Over 3000 calibrations were performed for approximately 2000 portable and fixed survey instruments. Response teams were identified in support of the Radiological Assistance Program (RAP). Documentation, procedures, and equipment for the RAP vehicle were upgraded. A long-range environmental plan was issued early in the year and again in June 1984 to document the scope and justification for each project. The DEM is developing an environmental information system for managing DOE-ORO and ORNL environmental data. Five hundred eighty-four waste disposal requests containing 5769 items were handled by the Hazardous Materials Control Group during 1984. The Office of Operational Safety made significant progress in the completion of Safety Analysis Reports for existing facilities. The Radiation and Safety Surveys Department is becoming increasingly involved in work resulting in facility improvement, repair, or upgrade as well as decontamination and decommissioning of older facilities

Balance of the tropospheric ozone and its relation to stratospheric intrusions indicated by cosmogenic radionuclides. Part 13. Annual report, 1 February 1982-31 January 1983

International Nuclear Information System (INIS)

Reiter, R.; Kanter, H.J.; Jaeger, H.; Munzert, K.

1985-06-01

A statistical evaluation of tropospheric ozone concentrations in the air obtained at 3 different levels is presented from data covering 1977 to 1984. Annual and interannual variations are used to project a trend. To clarify the climatology of the stratospheric exchange, the measuring series of cosmogenic radionuclides Be7, P32, P33 covering the period 1970 through 1981 are statistically analyzed with regard to the ozone concentration recorded on the Zugspitze. The statistics of stratospheric intrusions is shown and the stratospheric residence time is estimated. Effects of the eruption of volcano El Chichon in April 1982 on the concentration of the stratospheric aerosol are documented. The time variation of the concentration of the stratospheric aerosol is studied with consideration of the stratospheric circulation. The noted effects are weighed by a comparison with earlier volcanic eruptions. First results of CO 2 recordings in the lower stratosphere are presented. Based on CO 2 recording series from two different levels (740 m and 1780 m a.s.1) from the years 1978 to 1980, systematic differences are shown as a function of height. The question of sources and sinks is discussed to assess the contribution from anthropogenic sources

Concentrations of radionuclides in fish collected from Bikini Atoll between 1977 and 1984

International Nuclear Information System (INIS)

Noshkin, V.E.; Wong, K.M.; Eagle, R.J.; Jokela, T.A.; Brunk, J.A.

1986-07-01

This report summarizes all available data on the concentrations of radionuclides in fish from Bikini Atoll between 1977 and 1984. As found in other global studies, 137 Cs is most highly accumulated in edible flesh of all species of fish, the lowest fractions are found in the bone or liver. The mean concentration of 137 Cs in muscle of reef fish from the southern part of the atoll is comparable to the global fallout concentration measured in market samples of fish collected from Chicago, Illinois, in 1982. 90 Sr is generally associated with non-edible parts of fish, such as bone or viscera. Twenty-five to fifty percent of the total body burden of 60 Co is accumulated in the muscle tissue; the remainder is distributed among the liver, skin, and viscera. The mean concentration of 60 Co in fish has been decreasing at a rate faster than radiological decay alone. Most striking is the range of 207 Bi concentrations among different species of fish collected at the same time and place. Highest concentrations of 207 Bi were consistently detected in the muscle (and other tissues) of goatfish and some of the pelagic lagoon fish. In other reef fish, such as mullet, surgeonfish, and parrotfish, 207 Bi was usually below detection limits by gamma spectrometry. Over 70% of the whole-body activity of 207 Bi in goatfish is associated with the muscle tissue, whereas less than 5% is found in the muscle of mullet and surgeonfish. Neither 239+240 Pu nor 241 Am is significantly accumulated in the muscle tissue of any species of fish. Apparently, 238 Pu is in a more readily available form for accumulation by fishes than 239+240 Pu. Based on a daily ingestion rate of 200 q of fish flesh, dose rates to individuals through the fish-food ingestion pathway are well below current Federal guidelines

Report on safety related occurrences and reactor trips January 1 - June 30, 1984

International Nuclear Information System (INIS)

1984-01-01

This is a systematically arranged report on all safety-related occurrences and reactor trips in Swedish nuclear power plants in operation during the period from January 1 to June 30 1984. It is based on the reports submitted by the utilities to the Swedish Nuclear Inspectorate according to Technical Specifications. Twice a year since 1974 the Inspectorate has issued a compilation on such reported occurrences and reactor trips. Starting with the compilation of the second half of 1982 some new features have been introduced. The most important change is that the volume of information has been increased. The full text, provided by the utilities when reporting the incidents, is now attached to the codified information and also the layout has been altered to facilitate reading. As in the previous reports the occurrences and reactor trips are arranged both alphabetically by facility name and chronologically by report number for each facility. Electricity generation charts for each facility are also presented. The primary purpose of this report is thus to present all the information furnished by the utilities when they submit their reports according to Technical Specifications. The only evaluation made by the Inspectorate is the categorization on the incidents. Like the previous reports this one also presents frequency of incidents as related to affected component, cause of incident etc. The difference is that only information reported by the utilities is used. This is the reason why a considerable proportion of the incidents are categorized as other component or other fault. Sometime in the future, however, the Inspectorate plants to put out a special report containing its own analyses of the most interesting events along with processed statistics and other information.

The aim of this study was to examine population trends from 1982 to 2012 in Finland for leisure time physical activity (LTPA), commuting physical activity (CPA), occupational physical activity (OPA), and total physical activity. Furthermore, time trends in physical activity by educational levels and body mass index (BMI) categories were explored. Data were collected in independent cross-sectional population surveys, implemented every 5 years from 1982 to 2012. The data comprised 21,903 men and 24,311 women. Participants underwent a health examination and filled in questionnaires. Information on LTPA, CPA, and OPA was used both separately and combined to create an index of total physical activity. Between 1982 and 2012, high LTPA has increased in men (from 21% to 33%) and women (from 12% to 27%). High CPA and high OPA have decreased in men (from 17% to 12% and from 48% to 36%, respectively) and women (from 30% to 20% and from 26% to 21%, respectively). Total physical activity has remained fairly stable. Differences by education and BMI have increased, particularly for LTPA. Marked changes in physical activity have taken place over time. Differences in LTPA and OPA have grown wider across educational groups and BMI categories. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The realization in Cadarache of the big Tokamak with superconducting coils TORE SUPRA is entered in 1982 in the active phase of construction. The most important bargains that have been striken are quoted; the toroidal, cryogenic and poloidal systems have been studied. The experimental programme of TFR Tokamak have been restarted: priority, in physics' programme has been given to ion cyclotron resonance heating. Diagnostics have been, beforehand, improved. ''Pellets'' injection is studied, and principally electron cyclotron resonance. On Tokamak Petula B totally renovated, studies on heating and creation of current in plasma are restarted by the mean of hybrid resonance waves. Works on ion sources and neutral atom injectors are evocated, so are works on sources and negative beams. Theoretical work are very briefly described in this report [fr

The waterfall paradox: How knickpoints disconnect hillslope and channel processes, isolating salmonid populations in ideal habitats

Science.gov (United States)

Waterfalls create barriers to fish migration, yet hundreds of isolated salmonid populations exist above barriers and have persisted for thousands of years in steep mountainous terrain. Ecological theory indicates that small isolated populations in disturbance-prone landscapes are at greatest risk of extirpation because immigration and recolonization are not possible. On the contrary, many above-barrier populations are currently thriving while their downstream counterparts are dwindling. This quandary led us to explore geomorphic knickpoints as a mechanism for disconnecting hillslope and channel processes by limiting channel incision and decreasing the pace of base-level lowering. Using LiDAR from the Oregon Coast Range, we found gentler channel gradients, wider valleys, lower gradient hillslopes, and less shallow landslide potential in an above-barrier catchment compared to a neighboring catchment devoid of persistent knickpoints. Based on this unique geomorphic template, above-barrier channel networks are less prone to debris flows and other episodic sediment fluxes. These above-barrier catchments also have greater resiliency to flooding, owing to wider valleys with greater floodplain connectivity. Habitat preference models further indicate that salmonid habitat is present in greater quantity and quality in these above-barrier networks. Therefore the paradox of the persistence of small isolated fish populations may be facilitated by a geomorphic mechanism that both limits their connectivity to larger fish populations yet dampens the effect of disturbance by decreasing connections between hillslope and channel processes above geomorphic knickpoints.

Boyd, Douglas D

2017-07-01

General aviation includes all civilian aviation apart from operations involving paid passenger transport. Unfortunately, this category of aviation holds a lackluster safety record, accounting for 94% of civil aviation fatalities. In 2014, of 1143 general aviation accidents, 20% were fatal compared with 0 of 29 airline mishaps in the United States. Herein, research findings over the past 30 yr will be reviewed. Accident risk factors (e.g., adverse weather, geographical region, post-impact fire, gender differences) will be discussed. The review will also summarize the development and implementation of stringent crashworthiness designs with multi-axis dynamic testing and head-injury protection and its impact on mitigating occupant injury severity. The benefits and drawbacks of new technology and human factor considerations associated with increased general aviation automation will be debated. Data on the safety of the aging general aviation population and increased drug usage will also be described. Finally, areas in which general aviation occupant survival could be improved and injury severity mitigated will be discussed with the view of equipping aircraft with 1) crash-resistant fuel tanks to reduce post-impact conflagration; 2) after-market ballistic parachutes for older aircraft; and 3) current generation electronic locator beacons to hasten site access by first responders.Boyd DD.

Radiochemical measurements of the concentrations of the 228 Th, 230 Th, and 232 Th have been carried out for a total of 38 individual samples of rain and snow collected at Fayetteville (36 N, 94 0 W), Arkansas, during the period between April 1982 and December 1983. The concentrations of 228 Th, 230 Th, and 232 Th in a total of 9 composite rain samples, each covering a period of three months, have been also determined radiochemically. The thorium isotope data thus obtained were compared with the results of measurements of the concentrations of uranium isotopes in these rain and snow samples, which were carried out in our laboratories by previous investigators. The eruption of El Chichon volcano in Mexico occurred on March 28, 1982, and was followed by the second phase consisting of two major eruptions of April 3 and April 4, 1982. Marked increases in the concentrations of thorium and uranium isotopes were observed during the months of January and February 1983, followed by small peaks in April and May 1983. The concentrations of the 23 2''Th and 238 U in rain samples collected at Fayetteville, Arkansas, decreased steadily during the second half of 1983. The ratios of 228 Th/ 232 Th and 230 Th/ 232 Th in rain also showed a marked increase during the first half of 1983. These results indicate that the thorium and uranium isotopes in rain during the first half of 1983 had their origin in a large amount of volcanic ash materials injected into the stratosphere by the 1982 eruption of El Chichon volcano in Mexico
