    Rill erosion can be a large portion of the total erosion in disturbed forests, but measurements of the runoff and erosion at the rill scale are uncommon. Simulated rill erosion experiments were conducted in two forested areas in the northwestern United States on slopes ranging from 18 to 79%. We compared runoff rates, runoff velocities, and sediment flux rates from...

    In the rill erosion process,run-on water and sediment from upslope areas,and rill flow hydraulic parameters have significant effects on sediment detachment and transport.However,there is a lack of data to quantify the effects of run-on water and sediment and rill flow hydraulic parameters on rill erosion process at steep hillslopes,especially in the Loess Plateau of China.A dual-box system,consisting of a 2-m-long feeder box and a 5-m-long test box with 26.8% slope gradient was used to quantify the effects of upslope runoff and sediment,and of rill flow hydraulic parameters on the rill erosion process.The results showed that detachment-transport was dominated in rill erosion processes; upslope runoff always caused the net rill detachment at the downslope rill flow channel,and the net rill detachment caused by upslope runoff increased with a decrease of runoff sediment concentration from the feeder box or an increase of rainfall intensity.Upslope runoff discharging into the rill flow channel or an increase of rainfall intensity caused the rill flow to shift from a stratum flow into a turbulent flow.Upslope runoff had an important effect on rill flow hydraulic parameters,such as rill flow velocity,hydraulic radius,Reynolds number,Froude number and the Darcy-Weisbach resistance coefficient.The net rill detachment caused by upslope runoff increased as the relative increments of rill flow velocity,Reynolds number and Froude number caused by upslope runoff increased.In contrast,the net rill detachment decreased with an increase of the relative decrement of the Darcy-Weisbach resistance coefficient caused by upslope runoff.These findings will help to improve the understanding of the effects of run-on water and sediment on the erosion process and to find control strategies to minimize the impact of run-on water.

  6. Modeling soil detachment capacity by rill flow using hydraulic parameters

    Science.gov (United States)

    Wang, Dongdong; Wang, Zhanli; Shen, Nan; Chen, Hao

    2016-04-01

    The relationship between soil detachment capacity (Dc) by rill flow and hydraulic parameters (e.g., flow velocity, shear stress, unit stream power, stream power, and unit energy) at low flow rates is investigated to establish an accurate experimental model. Experiments are conducted using a 4 × 0.1 m rill hydraulic flume with a constant artificial roughness on the flume bed. The flow rates range from 0.22 × 10-3 m2 s-1 to 0.67 × 10-3 m2 s-1, and the slope gradients vary from 15.8% to 38.4%. Regression analysis indicates that the Dc by rill flow can be predicted using the linear equations of flow velocity, stream power, unit stream power, and unit energy. Dc by rill flow that is fitted to shear stress can be predicted with a power function equation. Predictions based on flow velocity, unit energy, and stream power are powerful, but those based on shear stress, especially on unit stream power, are relatively poor. The prediction based on flow velocity provides the best estimates of Dc by rill flow because of the simplicity and availability of its measurements. Owing to error in measuring flow velocity at low flow rates, the predictive abilities of Dc by rill flow using all hydraulic parameters are relatively lower in this study compared with the results of previous research. The measuring accuracy of experiments for flow velocity should be improved in future research.

    Hydraulic mechanism of rill formation was studied theoretically and experimentally.It was assumed that the impact of varied boundary on overland flow results in fluctuating of water surface,and shock waves that may contribute to the formation of rills.Both theoretical derivation and laboratory experiments were used to compare the hydraulic characteristics of flows with and without shock waves.Results showed that shock waves can lead to an increase in flowdepth,flow velocity,and turbulence intensity.Consequently,flow shear stress or stream energy increase dramatically and rill headcuts may occur where shock waves converge.

  10. Lunar Sinuous Rilles: Analysis of Morphology, Topography, and Mineralogy, and Implications for a Thermal Erosion Origin

    Science.gov (United States)

    Hurwitz, D. M.; Head, J. W.; Wilson, L.

    2009-12-01

    One of the most enigmatic features observed within the lunar maria are sinuous rilles, meandering channel-like features ranging from tens of meters to several kilometers in width and from a few to several hundreds of kilometers in length. Sinuous rilles generally form within maria, but they also originate in adjacent highlands and continue in the highlands for considerable distances. Sinuous rilles originate in elongate or irregularly shaped depressions or in large crater-like features, and they can be characterized by single channels or channels nested within one another that end abruptly in maria, merge into other rilles, or shallow within maria until they are no longer detectable. Post-Apollo studies link sinuous rille formation with the emplacement of lava, and a growing appreciation for ascent and eruption of lunar magma led to hypotheses consistent with very high effusion rates of low-viscosity lava: [1] and [2] suggest that at the high Reynolds numbers expected for these eruptions, flow ceases to be laminar and becomes turbulent. In these environments, convective heat loss is more efficient than conduction, leading the substrate temperature to exceed its solidus temperature and promoting thermal erosion that leads to the carving of deep channels similar to sinuous rilles. To apply updated thermal erosion models [3], we have examined properties of sinuous rilles, including 1) source region topography and morphology to assess implications of source geometry for thermal erosion theories [4, 5]; 2) lengths to assess possible flow durations; 3) slopes in order to assess important parameters associated with thermal erosion; 4) marginal deposits in order to distinguish between leveed lava flows and thermally erosive flows; and 5) spectral properties of units in which sinuous rilles occur in order to assess the units that they may be eroding and to detect the presence of possible distal deposits. These properties will be used to assess and update theories of thermal

  13. Rill Erosion in Post Wildfire Forests after Salvage Logging

    Robichaud, Peter; Wagenbrenner, Joseph; Brown, Robert

    2016-04-01

    Despite the dominance of concentrated flow or rill erosion in the erosion processes especially in steep forest environments that have been affected by wildfire or management activities few studies have quantified these effects on rill erosion. This study quantified the effects of wildfire and post-fire timber salvage operations on rill runoff quantity, runoff velocity, and rill erosion. Simulated rill experiments were conducted at various sites in the Western US after wildfire and timber salvage operations. The onsite conditions consists of burned only, salvage logged, skid or snig trail, or skid trails with extra logging debris added. For each rill experiment, concentrated flow was applied at the top of the plot through an energy dissipater at five inflow rates for 12 min each. Runoff was sampled every 2 min and runoff volume and sediment concentration were determined for each sample. The runoff velocity was measured using a dyed calcium chloride solution and two conductivity probes placed a known distance apart. Runoff volume, runoff velocities, and sediment concentrations increased with increasing levels of disturbance. The burned only plots had lower runoff rates and sediment concentrations than any of the other disturbances. The salvage logged plots had greater responses than the burn only plots and the mitigation treatment had a marginal effect on runoff ratios, runoff velocities and sediment concentrations. These results suggest that additional disturbance after a wildfire can increase the erosional response and that proper erosion control mitigation may be an important consideration for post fire management to reduce onsite erosion.

    The purpose of the Hanford Safety Analysis and Risk Assessment Handbook (SARAH) is to support the development of safety basis documentation for Hazard Category 2 and 3 (HC-2 and 3) U.S. Department of Energy (DOE) nuclear facilities to meet the requirements of 10 CFR 830, ''Nuclear Safety Management''. Subpart B, ''Safety Basis Requirements.'' Consistent with DOE-STD-3009-94, Change Notice 2, ''Preparation Guide for U.S. Department of Energy Nonreactor Nuclear Facility Documented Safety Analyses'' (STD-3009), and DOE-STD-3011-2002, ''Guidance for Preparation of Basis for Interim Operation (BIO) Documents'' (STD-3011), the Hanford SARAH describes methodology for performing a safety analysis leading to development of a Documented Safety Analysis (DSA) and derivation of Technical Safety Requirements (TSR), and provides the information necessary to ensure a consistently rigorous approach that meets DOE expectations. The DSA and TSR documents, together with the DOE-issued Safety Evaluation Report (SER), are the basic components of facility safety basis documentation. For HC-2 or 3 nuclear facilities in long-term surveillance and maintenance (S&M), for decommissioning activities, where source term has been eliminated to the point that only low-level, residual fixed contamination is present, or for environmental remediation activities outside of a facility structure, DOE-STD-1120-98, ''Integration of Environment, Safety, and Health into Facility Disposition Activities'' (STD-1120), may serve as the basis for the DSA. HC-2 and 3 environmental remediation sites also are subject to the hazard analysis methodologies of this standard.

    SARAH is a Mathematica package optimized for the fast, efficient and precise study of supersymmetric models beyond the MSSM: a new model can be defined in a short form and all vertices are derived. This allows SARAH to create model files for FeynArts/FormCalc, CalcHep/CompHep and WHIZARD/OMEGA. The newest version of SARAH now provides the possibility to create model files in the UFO format which is supported by MadGraph 5, MadAnalysis 5, GoSam, and soon by Herwig++. Furthermore, SARAH also calculates the mass matrices, RGEs and 1-loop corrections to the mass spectrum. This information is used to write source code for SPheno in order to create a precision spectrum generator for the given model. This spectrum-generator-generator functionality as well as the output of WHIZARD and CalcHep model files have seen further improvement in this version.

    Lunar sinuous rilles are thought to have formed by thermal erosion, mechanical erosion, construction, or a combination of these processes via emplacement by lava tubes or lava channels. The investigation of Hadley Rille by Apollo 15 provided the first field observations of a rille, but remote sensing observations remain our primary method for studying these features. Terrestrial volcanic features with similar morphologies to lunar rilles can provide insight into their formation on the Moon.

    Full Text Available Claudia Thorun untersucht die Inszenierungen von Weiblichkeit am Beispiel der Schauspielerin Sarah Bernhardt, die im späten 19. und beginnenden 20. Jahrhundert zu den erfolgreichsten Künstlerinnen ihrer Zeit gehörte. Dazu werden die Darstellungen ausgewählter Rollenfiguren ebenso analysiert wie die schauspieltheoretischen Überlegungen Bernhardts und schließlich die Rezeption ihres Schaffens in Theaterkritiken, aber auch Werbebildern und Medieninszenierungen. Das lesenswerte Buch erlaubt Einblicke in konkrete theatrale Verkörperungen von Weiblichkeit im Fin de Siècle, unternimmt jedoch keine ausreichende theatergeschichtliche wie kulturwissenschaftliche Kontextualisierung, obwohl die Verfasserin in der Einleitung ihrer Studie das Ziel formuliert, Gendertheorie, Theatergeschichte und Kulturwissenschaft zu verknüpfen.Claudia Thorun examines the staging of femininity using the example of the actress Sarah Bernhardt, who in the late nineteenth century was among the most successful artists of her time. The study includes analyses of the representation of specific roles, Bernhardt’s theories on acting, and finally the reception of her work in theater critiques, as well as advertisement images and representations in the media. The book, which is a worthwhile read, allows for insight into the concrete theatrical embodiment of femininity at the fin de siècle. It does not provide, however, adequate contextualization within theater history nor cultural studies, even though in her introduction, the author asserts that it is her intention to link together gender theory, theater history, and cultural studies.

  19. Physical Model Study: Rill Erosion Morphology and Flow Conditions

    Using common catchment size erosion model software either lack of knowledge or lack in process ability of watershed characteristics leads to increasing simplifications in model assumptions. Referring to open channel hydraulics, erosion model equations are prevalently based on stepwise uniform flow condition requirements. Approaching balance of gravitational and frictional resistance forces, channel roughness is fundamental model input. The fusion of simplified model assumptions and the use of lumped roughness determination cause ambivalence in model calibration. By means of a physical model experiment at the National Soil Erosion Laboratory (NSERL), West Lafayette, USA, channel roughness was itemized into skin friction and channel shape friction due to rill morphology. Particularly the Manning-Strickler equation was analyzed concerning the applicability of constant and holistic factors describing boundary friction impacts. The insufficiency in using the Manning-Strickler equation for non-uniform flow conditions is widely advised, whereas lack in predictability in rill erosion development inhibits proper model adoptions. The aim of the present study is to determine the impact of channel morphology on roughness assessment in rill erosion scale. Therefore a 1.9 meter long, 0.6 meter wide and 0.3 meter deep flume with an inclination of 10 % was filled with a loamy soil representing a section of a hill slope. The soil was prepared and saturated by simulated rainfall before each model run. A single erosion channel was enforced to develop by means of steady state runoff. Two different erosion channel types were initiated and observed: I.) a Straight Constrained Rill (SCR) shape by concentration of the runoff into a prepared straight initial rill and II.) a Free Developing Rill (FDR) by back-cut erosion through the plain soil body. Discharge of the outflow was measured in 5 minute interval and outflow sediment concentration was measured every minute. A top view stereo

    Full Text Available The presence of compacted layers in soils can induce subprocesses (e.g., discontinuity of water flow and induces soil erosion and rill development. This study assesses how rill erosion in Oxisols is affected by a plow pan. The study shows that changes in hydraulic properties occur when the topsoil is eroded because the compacted layer lies close below the surface. The hydraulic properties that induce sediment transport and rill formation (i.e., hydraulic thresholds at which these processes occur are not the same. Because of the resistance of the compacted layer, the hydraulic conditions leading to rill incision on the soil surface differed from the conditions inducing rill deepening. The Reynolds number was the best hydraulic predictor for both processes. The formed rills were shallow and could easily be removed by tillage between crops. However, during rill development, large amounts of soil and contaminants could also be transferred.

    Full Text Available Rill erosion models are important to hillslope soil erosion prediction and to land use planning. The development of rill erosion models and their use has become increasingly of great concern. The purpose of this research was to develop mathematic models with computer simulation procedures to simulate and predict rill erosion. The finite element method is known as an efficient tool in many other applications than in rill soil erosion. In this study, the hydrodynamic and sediment continuity model equations for a rill erosion system were solved by the Galerkin finite element method and Visual C++ procedures. The simulated results are compared with the data for spatially and temporally measured processes for rill erosion under different conditions. The results indicate that the one-dimensional linear finite element method produced excellent predictions of rill erosion processes. Therefore, this study supplies a tool for further development of a dynamic soil erosion prediction model.

  2. Using REE Tracers to Measure Sheet Erosion Changing to Rill Erosion

    2003-01-01

    Rare earth element(REE) tracer method was used to study sheet erosion changing to rill erosion on slope land. By placing different REE on different soil depth across a slope in an indoor plot, two simulated rainfalls were applied to study the change of erosion type and the rill erosion process. The results indicate that the main erosion type is sheet erosion at the beginning of the rainfalls, and serious erosion happens after rill erosion appears. Accumulated sheet and rill erosion amount increases with the rainfalls time. The percentage of sheet erosion amount decreases and rill erosion percentage increases with time. At the end of the rainfalls, the total rill erosion amounts are 4.3 and 5 times more than sheet erosion. In this paper, a new REE tracer method was used to quantitatively distinguish sheet and rill erosion amount. The new REE tracer method should be useful to future studying of erosion processes on slope lands.

  3. Applicability of different hydraulic parameters to describe soil detachment in eroding rills.

    2013-01-01

    This study presents the comparison of experimental results with assumptions used in numerical models. The aim of the field experiments is to test the linear relationship between different hydraulic parameters and soil detachment. For example correlations between shear stress, unit length shear force, stream power, unit stream power and effective stream power and the detachment rate does not reveal a single parameter which consistently displays the best correlation. More importantly, the best fit does not only vary from one experiment to another, but even between distinct measurement points. Different processes in rill erosion are responsible for the changing correlations. However, not all these procedures are considered in soil erosion models. Hence, hydraulic parameters alone are not sufficient to predict detachment rates. They predict the fluvial incising in the rill's bottom, but the main sediment sources are not considered sufficiently in its equations. The results of this study show that there is still a lack of understanding of the physical processes underlying soil erosion. Exerted forces, soil stability and its expression, the abstraction of the detachment and transport processes in shallow flowing water remain still subject of unclear description and dependence.

    Rills are commonly found on sloping farm fields in both the loess and the purple soil regions of China. A comparative study on rill erosion between the two soils is important to increase research knowledge and exchange application experiences. Rill erosion processes of loess and purple soils were determined through laboratory experiments with the volume replacement method. Water was used to refill the eroded rill segments to compute eroded volume before sediment concentration distribution along the rill was computed using the soil bulk density, flow rate, and water flow duration. The experimental loess soil materials were from the Loess Plateau and purple soil from the southwestern part of China, Chongqing City. A laboratory experimental platform was used to construct flumes to simulate rills with 12.0 m length, 0.1 m width, and 0.3 m depth. Soil materials were filled into the flumes at a bulk density of 1.2 g cm-3 to a depth of 20 cm to form rills for experiments on five slope gradients (5°, 10°, 15°, 20°, and 25°) and three flow rates (2, 4, and 8 L/min). After each experimental run under the given slope gradient and flow rate, the rill segments from the upper slope between 0-0.5, 0.5-1, 1-2, 2-3, …, 7-8, 8-10, and 10-12 m were lined with plastic sheets before be re-filled with water to determine sediment concentration after the eroded volumes was measured. Rill erosion differed between the two soils. As purple soil started to erode at a higher erosive force than loess soil, it possibly exhibits higher resistance to water erosion. The subsequent erosion process in the eroding purple rill was similar to that in the loess rill. However, the total erosion in the eroding loess rill was more than that in the eroding purple rill. The maximum sediment concentration transported by the eroding purple rills was significantly lower, approximately 55% of those transported by the loess rills under the same flow rate and slope gradient. Hence, less purple sediments can

    The initiation of rill erosion marks the transition from sheet to linear erosion. With this transition, the relevant processes change and therefore, the observation method needs to be changed too: from observing rainfall induced drop impacts to hydraulic observations. For us, the investigation of the decisive processes in eroding rills resulted in a constantly revised and updated rill erosion experiment, that has been used for several years. Within this experiment the sediment transport behavior of rills is simulated and examined. To make the experiment repeatable and replicable, several key-variables have to be kept constant, i.e. water quantity (1000 L), test duration (approx. 4 min.) and the length of the tested rill section (20 m). For each tested rill, the topographic background is determined i.e. catchment area, aspect, slope, position and height of existing knick-points and three cross-sections. After the initial assessment, the rill is flushed with water (250 L min -1) twice in order to determine the modifications of the rill caused by the flowing water. Within these approx. 4 minutes of "controlled destruction" the velocity of the turbulently flowing water at the beginning of the erosional event and after one and two minutes is determined and the corresponding water depth is recorded using three gauges at selected measuring points. At the end of the tested rill segment, the discharge is constantly monitored. Unfortunately, the results of this rill experiment do not directly show the modifications caused by the artificial waterflow. A way out of this knowledge gap is offered by combining this experimental measurement method with a technique already used in different scientific disciplines in more large-scale applications. Structure-from-Motion technology offers the opportunity to get a different, more detailed view inside the erosion rills. A static multi-camera-array and a dynamically moved digital video-frame camera are now used to obtain three

    Soil erosion has been studied by many scientists for decades (Zingg, 1940; Meyer & Wischmeier, 1969; Foster, 1982; Luk, 1988) and many soil erosion prediction equations have already been developed, such as USLE, RUSLE. In spite of WEEP is based on hydrological physical model, all of the above models are restricted to predict concentrate flow. On the other hand, rill erosion is not understood completely. The amounts of rill erosion are always underestimated. Rill Erosion correlate closely to gradient (Cerda & Garcia-Fayos, 1997; Fox & Bryan, 1999; Fu,et al., 2011; Clarke & Rendell, 2006), slope length (Gabriel, 1999; Yair, 2004), particle distribution (Gabriel, 1999), proportion of clay (Luk,1977; Bryan2000), rainfall intensity (Römkens et al. 2001), and land use (Dotterweich, 2008). However, the effect of micromorphology of mud rock surface, such as mud-cracks, could be studied in more details. This research aims to simulate rill development by hydraulic flume to observe the morphological change caused by rill/erosion process. Mudstone specimens sampled from the mudstone area of Long-Chi, southern Taiwan. The results show that: (1) The erosion pattern of mudstone slope can be divided into four steps: (a) inter-rill erosion, ( b) rill erosion, (c) rill development, (d) slope failure. (2) Slopes with mud-cracks caused 125% soil loss than smooth slopes. (3) Mud-cracks affect spatial distribution of rill development (4) The sediment concentration decreased sharply in the beginning of experiments, however increased due to rill development. This paper demonstrated such a rill development. 1: Department of Geography, National Taiwan University. E-mail:maxpossibilism0929@gmail.com

    Experimental studies provide a basis for understanding the mechanisms of rill erosion and can provide estimates for parameter values in physical models simulating the erosion process. In this study, we investigated sediment delivery during rill erosion in purple soil. We used the volume-replacement method to measure the volume of eroded soil and hence estimate the mass of eroded soil. A 12 m artificial rill was divided into the following sections: 0-0.5 m, 0.5-1 m, 1-2 m, 2-3 m, 3-4 m, 4-5 m, 5-6 m, 6-7 m, 7-8 m, 8-10 m, and 10-12 m. Erosion trials were conducted with three flow rates (2 L/min, 4 L/min, and 8 L/min) and five slope gradients (5°, 10°, 15°, 20°, and 25°). The eroded rill sections were refilled with water to measure the eroded volume in each section and subsequently calculate the eroded sediment mass. The cumulative sediment mass was used to compute the sediment concentration along the length of the rill. The results show that purple soil sediment concentration increases with rill length before eventually reaching a maximal value; that is, the rate of increase in sediment concentration is greatest at the rill inlet and then gradually slows. Steeper slopes and higher flow rates result in sediment concentration increasing more rapidly along the rill length and the maximum sediment concentration being reached at an earlier location in the rill. Slope gradient and flow rate both result in an increase in maximal sediment concentration and accumulated eroded amount. However, slope gradient has a greater influence on rill erosion than flow rate. The results and experimental method in this study may provide a reference for future rill-erosion experiments.

  14. A non-Markovian model of rill erosion

    Winter, C.; Damron, M.

    2009-12-01

    Stochastic processes with reinforcement are inherently non-Markovian and therefore may model geophysical processes with memory, for instance patterns of rill erosion, more realistically than Markovian models. Reinforcement provides a bias to a system that is equivalent to infinite memory, making a system more likely to occupy a given state the more often the state is visited. Some well-studied examples in applied mathematics include variations on the urn of P'olya and reinforced random walks. Many natural phenomena exhibit similar behavior: for instance, an overall pattern of rills is relatively stable once it is established, although small details of the pattern may change frequently and catastrophes that permanently alter it may occasionally occur. To model the phenomenology of rill erosion, we propose a simple discrete time, infinite-memory random process defined on the nodes and edges of an oriented diagonal lattice. Lattice models have often been used to investigate the morphology of natural drainage networks, but our focus is as much on the dynamics of network formation as it is on morphology. The lattice in our model starts out smooth in the sense that it has no edges initially, but it sprouts edges everywhere the instant the process starts, much as rain can start soil erosion everywhere on a hillslope at once. Exactly one edge (rill segment) descends from each node, and it points either left or right. Sediment loads travel along networks of edges and are accumulated at nodes. At every node and at every time step, a simple two parameter reinforcing law randomly determines the direction of the node’s output and then is updated. The degree of reinforcement is set by comparing the node's current sediment load to the load history of the entire network above it and is governed by two system parameters representing respectively rainfall intensity and the soil’s resistance to change. The current pattern of connections among nodes represents the present state of

    Sheet/rill erosion, dust displacement, and vehicle induced splash are the primary sediment transport processes on off-highway vehicle (OHV) trails in the Ouachita Mountains of the central United States. The relative importance of these three processes is assessed by comparing the area affected and the sediment connectivity of each process to affected streams using field data from the Wolf Pen Gap Trail Complex. The occurrence and areal extent of erosion processes were assessed using systematic transect measurements, feature inventories, and visual observation over representative trail segments. Sheet/rill erosion affects the entire denunded surface of the trail system, an area of 2,820 m2 km-1 of trail. Distinct erosion features created by sheet/rill erosion occur 16.3 times per km. Dust transport extends a mean travel distance of 3.7 m off-trail. Dust transport affects both the entire trail area and an additional 6,640 m2 km-1 of off-trail area. In contrast, splash transport was restricted to trail dips, and extends 1.6 m off-trail. Splash transport affects 60 m2 km-1of off-trail area.The impact of trail erosion increases where sediment sources are connected to drainageways. Of 480 sheet/rill erosion features rated, 69.4% had high to very high connectivity to channels. All sampled dips were directly connected to drainage ways. Dust transport affected 99% of dips on one trail side and 90% on both sides. About 80% of the dips had splash transport on one trail side and 42% on both sides.Sheet/rill, dust, and splash transport processes are all important in the Trail Complex, but for different reasons. Sheet/rill erosion affects the entire trail surface, is well connected to area drainageways, but only occurs after rainfall. Dust transport affects the largest area and occurs most often throughout the year, but the sediment is deposited diffusely, and the ratio delivered to the drainage network is relatively low. Splash affects the smallest area and is limited to short

  20. Erosion rills offset the efficacy of vegetated buffer strips to mitigate pesticide exposure in surface waters.

    Regulatory risk assessment considers vegetated buffer strips as effective risk mitigation measures for the reduction of runoff-related pesticide exposure of surface waters. However, apart from buffer strip widths, further characteristics such as vegetation density or the presence of erosion rills are generally neglected in the determination of buffer strip mitigation efficacies. This study conducted a field survey of fruit orchards (average slope 3.1-12.2%) of the Lourens River catchment, South Africa, which specifically focused on the characteristics and attributes of buffer strips separating orchard areas from tributary streams. In addition, in-stream and erosion rill water samples were collected during three runoff events and GIS-based modeling was employed to predict losses of pesticides associated with runoff. The results show that erosion rills are common in buffer strips (on average 13 to 24 m wide) of the tributaries (up to 6.5 erosion rills per km flow length) and that erosion rills represent concentrated entry pathways of pesticide runoff into the tributaries during rainfall events. Exposure modeling shows that measured pesticide surface water concentrations correlated significantly (R(2)=0.626; pmodeling approach in which buffer strip width was set to zero at sites with erosion rills; in contrast, no relationship between predicted runoff losses and in-stream pesticide concentrations were detected in the modeling approach that neglected erosion rills and thus assumed efficient buffer strips. Overall, the results of our study show that erosion rills may substantially reduce buffer strip pesticide retention efficacies during runoff events and suggest that the capability of buffer strips as a risk mitigation tool for runoff is largely overestimated in current regulatory risk assessment procedures conducted for pesticide authorization.

    2015-11-01

    Full Text Available Photogrammetry from aerial pictures acquired through micro Unmanned Aerial Vehicles (UAV, integrated by post-processing is a promising methodology both in terms of speed of data acquisition, degree of automation of data processing and cost-effectiveness. The new UAV-GIS methodology has been developed for three main purposes: i for a quick measurement of rill erosion at a field scale with the aim of combining the simplicity of field survey to reliability of results, at an affordable price; ii to calibrate the RUSLE model to make it suitable for the purposes of the CAP common indicator; iii to provide an easy evaluation tool to Regions and to non-research professionals who use the very popular ESRI ArcGis software for assessing the effectiveness of soil conservation measures adopted under CAP and to calibrate the common indicator “soil erosion by water”. High-resolution stereo photos pairs, acquired close to the soil, are of crucial importance in order to produce high resolution DEMs to be analysed under GIS. The GIS methodology consists of the measurement of rill erosion that occurred in a plot from the total volume of the incisions, regardless of internal sediment redeposition, based on Plan Curvature analysis and Focal Statistics analysis, described in detail, as they are the essential constituents of the new methodology. To determine the effectiveness and reliability of the new methodology a comparison between rill depth measured manually on field of 51 rill points and depth measured by UAV-GIS methodology was done. The best calibration equation was obtained by using 30 cm radius in the Focal statistics analysis. The linear regression equation resulted highly significant with R2 =0.87. Two case studies are presented, solved step by step, in order to help the user to overcome possible difficulties of interpretation in the application of the GIS procedure. The first solved exercise concerns a heavily eroded plot where only one DEM, derived

    2001-01-01

    Rill erosion is a dominant process of morphological evolution of the Loess Plateau in China, and deliveries much loess sediment to rivers. Data from two flume experiments conducted on the bare and glass-covered beds indicated that the fill flow develops into a series of rolling waves. The shear stress on the rill bed distributes unevenly both spatially and temporally. A new method based on the energy conservation law is proposed in this study. Thus the relationship between the runoff energy consumption from the interaction of water flow and slope bed and soil detachment is formulated. The results showed that the data for the soil detachment rate on slope (Dr) and the energy consumption of runoff (E1) fitted well with newly-developed function. The rill erosion occurs when the runoff energy consumption exceeds a critical value.

    Full Text Available The paper explores the nexus between intercultural storytelling and intercultural learning. Noting the wide appeal of the travel memoir set in France, it takes as a case study a book that, while positioned within that genre, attempts to shift some predictable patterns: Sarah Turnbull’s best-selling Almost French. Analysis shows that the book in fact participates in a subtle play of genres, whereby the lure of the travel memoir is used to entice readers towards a position where they read the book as a guide to French culture. The particular form of hybridity attempted is, however, a delicate enterprise, as the reception of the book demonstrates, in that the intercultural lessons on offer risk being overshadowed by the expectations readers bring to the genre of the travel memoir. The paper examines the competing seductions operating throughout the text and relates the conditions for taking up the opportunity for intercultural learning to questions of genre. It offers a pedagogical uptake of the textual analysis, thus bridging disciplines in a way that mirrors Turnbull’s bridging of genres.

  15. Terrestrial photography as method to identify sediment sources in eroding rills

    Science.gov (United States)

    Wirtz, Stefan; Remke, Alexander; Wengel, René; Seeger, Manuel; Ries, Johannes B.

    2013-04-01

    One weak point in available studies on erosion processes in eroding rills is the lack of information about the real source of transported sediment. So far, such sources can only be identified by observation during the event or the experiment. Quantification is not possible by this way, additionally only large and clear visible changes are considered. In this study we present a method to quantify even small topographical changes in eroding rills during experiments or real rainfall events. We tested the suitability of DEMs created from terrestrial stereo photographies before and after application of artificial runoff to quantify eroded, transported and sedimented material in the rill. In 1 m intervals, pairs of photos are taken along the tested rills. The setup ensures that both cameras are moved with a constant parallax. The height of only about 1 m above ground level ensures that even low quantities of moved material can be identified. Based on technical data of the camera and the shot level, the theoretical accuracy of the images is below 1 mm horizontal ground resolution. The camera carrier bases on a rotating tower crane which has been developed from a customary survey tripod. The stereo images are combined with free-hand photographies from different angles of view to reach overhangs in rill sidewalls and ensure a fully 3D representation of the rill. In the analyses of the photographies 2 different kinds of software are used: The standard software Leica Photogrammetry Suite requires stereo images and ground control points whereas the open source software package is able to handle either stereo images as well as free-hand photographies. Ground control points are not needed, the software identifies point clusters which are to find in overlapping images. Using these feature-points, spatial marks are positioned which are used to match and rectify the single images to get an apposite panorama. By this way images from very different angles of view can be combined. The

  16. Using 7Be measurements to estimate the relative contributions of interrill and rill erosion

    2014-02-01

    Rapid and reliable methods for estimating the relative contribution of interrill and rill erosion during a rainfall event are needed to provide an improved understanding of soil erosion processes and to develop process-based soil erosion prediction models. Use of the radionuclide 7Be in controlled experiments provides a means of addressing this need and this paper reports an experimental study aimed at refining and testing procedures employed to estimate the relative contribution of the two components of erosion. Four experimental plots (area 5 × 2 m and 10°, 15°, 20°, and 25° slope), filled with a loessial soil, manually tilled, and kept free of weeds with herbicides, were subjected to high intensity rainfall (91.8-120.6 mm h- 1), in order to induce rill development. The evolution of the rill network was documented photographically during the rainfall events and the runoff and sediment output from the plots were collected and measured. The sediment was recovered from the runoff and its mass and 7Be activity were measured. The Yang model, reported previously, was used to estimate the relative contributions of interrill and rill erosion from the 7Be activity of the exported sediment and this model was further refined to take account of the dynamic growth of the rills during the rainfall event. The results from the experiments were also used to develop a simple empirical linear model for estimating the relative contributions of interrill and rill erosion from the 7Be measurements. A comparison of the results provided by the three models showed some differences in the estimates of the magnitude of the relative contributions, although their trend during the event was similar. The estimates provided by the empirical linear model tended to be higher than those obtained using the refined model and lower than those generated by the Yang model, but were closer to those provided by the refined model which was seen as being theoretically the most accurate model.

    Rill erosion processes generate preferential flow paths that may increase the degree of connectivity of the soil surface and hence strongly modify its hydrological response. However, few studies have tried to quantify the effect of rill development on overland flow connectivity. For this purpose, changes in surface microtopography were monitored on three bare agricultural plots (3 m wide x 10 m long and 11% of slope) in Louvain-la-Neuve (Belgium) under natural rainfall conditions. Digital elevation models of these plots were obtained on a monthly basis over a 1-year period by photogrammetry using the Micmac software. Runoff was collected at the plot outlets. To characterize the hydrological connectivity, a functional connectivity indicator was used, called the relative surface connection function (RSCf). This indicator, which relates the area connected to the outflow boundary to the degree of filling of maximum depression storage (MDS), is fast to compute and was previously shown to be able to capture runoff-relevant connectivity properties. The RSC function was calculated for each DEM and the evolution of overland flow connectivity was quantified and compared to the measured runoff. The results of this study showed that the changes in microtopography resulting from sheet and rill erosion have a strong impact on the hydrological connectivity as reflected in the RSCf. A higher volume of runoff was generated as a consequence of surface sealing and the decrease of the MDS. More rapid runoff initiation was observed as the RSCf evolved from a concave to a convex shape.

  2. EVALUATION OF RILL AND EPHEMERAL GULLY EROSION IN CULTIVATED AREAS OF NAVARRE (SPAIN)

    2005-01-01

    Although there is much evidence of intense soil erosion in cultivated areas of Navarre (Spain), scarce information currently is available regarding soil loss rates, the spatial and temporal distribution of erosion, and the factors controlling these processes. Rills and ephemeral gullies are frequently responsible for a high percentage of total soil erosion, and these features can be considered a good approximation for the minimum erosion rates. With the main purpose of determining the annual soil loss rates in cultivated areas of Central Navarre, a detailed assessment of rainfall and rill and gully erosion was made in 19 small watersheds cultivated with winter grains or vineyards. The study period spanned from 1995 to 2001. For cereal watersheds, soil losses were caused by only one or two rainfall events each year. High erosion rates were observed (0.20-11.50 kg/m2 per year). In vineyards, soil losses were caused by several rainfall events each year, occurring year round. High erosion rates were observed in these vineyards (0.33 y 16.19 kg/m2 per year). No erosion was observed in those cultivated watersheds with no-till practices. It can be concluded that rill and ephemeral gully erosion can be very significant in Mediterranean regions, and much more attention should be paid to the problem.

    The French Lieutenant’s Woman is the best-known novel written by John Fowles and is also called the post-modern metafiction. In the novel the mysterious woman Sarah is introduced, who rebels against Victorian conventions to pursue indepen-dence and freedom. Undoubtedly, Sarah is an independent woman ahead of her times. This paper is attempted to interpret the last ending of The French Lieutenant’s woman written by John Fowles, thus finding relevant evidence to support this interpreta-tion that Sarah has finally got her freedom which is not allowed against the Victorian background.

  4. Chemostratigraphy of glaciomarine sediments in the Sarah Formation, northwest Saudi Arabia

    2016-05-01

    The Sarah Formation of northern Saudi Arabia mainly consists of glacial 'outwash' sediments deposited by turbidite channels and fans. Prior to undertaking chemostratigraphy, the results of seismic interpretation revealed the Sarah Formation to be mainly deposited in a NW-SE trending turbidite system in the study area, comprising channels with associated fans. These are succeeded by fluvio marine sediments at the top of the Sarah Formation. In the absence of good biostratigraphic control, chemostratigraphy was found to be one of the few techniques that could be employed to produce a high resolution correlation scheme for four study wells. Geochemical data were acquired for 50 elements in 550 core samples by ICP-OES (Inductively Coupled Plasma - Optical Emission Spectrometry) and ICP-MS (Inductively Coupled Plasma - Mass Spectrometry) but only the 'key' ratios Zr/Nb, Nb/Ti, Nb/Cr, Rb/K and Th/Cr were employed for chemostratigraphic purposes as they show significant trends that enable correlative boundaries to be identified and a hierarchical scheme to be proposed. Variations in these parameters are largely related to changes in source/provenance. In order to avoid geochemical variations relating to changes in grain size/lithology, separate schemes were proposed for the sandstone and mudrock samples. The sandstone scheme consists of a hierarchical order of three zones, seven subzones and five divisions, while the mudrock scheme is less detailed, comprising three zones and seven subzones. A 'finalised' scheme, based on a combination of the two aforementioned ones, was found to be more useful than employing the correlation proposed for individual lithologies. One of the main conclusions of the study was that the basal chemozones (general term used to describe any chemostratigraphic zone, subzone or division) were identified in wells B and C but were missing from A and D. It is thought that the areas around the two latter wells represented topographically 'high' areas

    Vineyards are one of the most German conditioned eco-geomorphological systems by human activity. Precisely, the vineyards of the Ruwer Valley (Germany) is characterized by high soil erosion rates and rill problems on steep slopes (between 23-26°) caused by the increasingly frequent heavy rainfall events, what is sometimes enhanced by incorrect land use managements. Soil tillage before and after vintage, application of vine training systems and anthropic rills generated by wheel tracks and footsteps are observed along these cultivated area. The objective of this paper is to determine and to quantify the hydrological and erosive phenomena in two chosen vineyards, during diverse seasons and under different management conditions (before, during and after vintage). For this purpose, a combined methodology was applied. Investigating climatic, pedological, geomorphological and botanic-marks variables was suggested on the two experimental plot in the village of Waldrach (Trier, region of Rhineland-Palatinate). First, high infiltration rates (near 100%) and subsurface flow was detected by rainfall simulations performed at different times of the year. The second method to investigate the geomorphological response of slope inclination, two 10 m and one 30 m long rills were measured using geometrical channel cross-section index, depth and width. The highest variations (lateral and frontal movements) were noted before and during vintage, when footsteps occurred in a concentrated short time. Finally, two maps were generated of soil loss, indicated by the botanic marks on the graft union of the vines. As results 62.5 t-1 ha-1 yr-1 soil loss rate was registered (one year) on the experimental plots of the new vineyards, while 4.3 t-1 ha-1 yr-1 on the old one.

  11. A rill erosion-vegetation modeling approach for the evaluation of slope reclamation success in water-limited environments

    2013-04-01

    Slope reclamation from surface mining and road construction usually shows important constraints in water-limited environments. Soil erosion is perceived as a critical process, especially when rill formation occurs, as rills can condition the spatial distribution and availability of soil moisture for plant growth, hence affecting vegetation development. On the other hand, encouraging early vegetation establishment is essential to reduce the risk of degradation in these man-made systems. This work describes a modeling approach focused on stability analysis of water-limited reclaimed slopes, where interactive relationships between rill erosion and vegetation regulate ecosystem stability. Our framework reproduces two main groups of trends along the temporal evolution of reclaimed slopes: successful trends, characterized by widespread vegetation development and the effective control of rill erosion processes; and gullying trends, characterized by the progressive loss of vegetation and a sharp logistic increase in erosion rates. Furthermore, this analytical approach allows the determination of threshold values for both vegetation cover and rill erosion that drive the system's stability, facilitating the identification of critical situations that require specific human intervention (e.g. revegetation or, in very problematic cases, revegetation combined with rill network destruction) to ensure the long-term sustainability of the restored ecosystem. We apply our threshold analysis framework in Mediterranean-dry reclaimed slopes derived form surface coal mining (the Teruel coalfield in central-east Spain), obtaining a good field-based performance. Therefore, we believe that this model is a valuable contribution for the management of water-limited reclaimed systems, as it can play an important role in decision-making during ecosystem restoration and provides a tool for the assessment of restoration success in severely disturbed landscapes.

    The authors investigated the early women physicians of the New York Infirmary for Women and Children and their role in shaping the career and accomplishments of their student and later colleague, Dr. Sarah J. McNutt. These influences eventually led McNutt to be inducted into the American Neurologic Association (ANA). McNutt was educated at the New York Infirmary for Women and Children by early women physicians including Drs. Elizabeth and Emily Blackwell and Mary Putnam Jacobi. McNutt worked to improve the educational opportunities for practicing physicians and nurses by developing postgraduate lectures and organizations. With her early colleagues she developed the New York Infirmary for Women and Children into a reputable hospital and woman's medical college. One of the consultants to the New York Infirmary for Women and Children was Royal W. Amidon, secretary of the ANA in 1883. McNutt's close association with the Clinical Society of the New York Post Graduate Medical School and Hospital brought her into direct contact with other prominent ANA members including C.L. Dana and W.A. Hammond. In 1884, McNutt was nominated by Amidon and Hammond as the first woman member to the ANA and was elected. Her ANA thesis was Double Infantile Spastic Hemiplegia. McNutt was elected into the ANA at a time when women physicians were first being recognized and included into mainstream medicine. Her historic election acknowledged her accomplishments and highlighted the proactive role of the early ANA in forging new medical policies in the United States.

    century, the parisian perfumery of Sarah Felix was famous especially for her cosmetic "L'Eau des Fées" ("Water of the Fairies"), a dyeing supposed to give back to the old hair the color of their youth. Sarah Felix, sister of the famous actress Rachel, exercised several jobs before becoming perfumer. At first, she was actress, then she tried ... oyster culture in Normandy ! Abandoning these activities, Sarah Felix became really a businesswoman in Paris. She dedicated herself to perfumery, in particular to "L'Eau des Fées", from 1866. To launch its product, she was associated to competency characters (engineer, pharmacist, physician) and benefited from the protection of the imperial family. A lawsuit between the associates and the 1870 war hindered the company's early days, but "L'Eau des Fées" provided with quality pledges, imposed itself definitely. The "Parfumerie des Fées" completed the range of its cosmetics with creams, powders, etc. Sarah Félix paid attention to present "L'Eau des Fées" as a dye devoid of toxicity. Was it really the case and could il be sold nowadays? These two issues are discussed in the last part.

    Several watersheds cross the US-Mexico boundary, resulting in trans-boundary environmental problems. Erosion in Tijuana, Mexico, increases the rate of sediment deposition in the Tijuana Estuary in the United States, altering the structure and function of the ecosystem. The well-being of residents in Tijuana is compromised by damage to infrastructure and homes built adjacent to stream channels, gully formation in dirt roads, and deposition of trash. We aim to understand the dominant source of sediment contributing to the sediment budget of the watershed (channel, gully, or rill erosion), where the hotspots of erosion are located, and what the impact of future planned and unplanned land use changes and Best Management Practices (BMPs) will be on sediment and storm flow. We will be using a mix of field methods, including 3D photo-reconstruction of stream channels, with two models, CONCEPTS and AnnAGNPS to constrain estimates of the sediment budget and impacts of land use change. Our research provides an example of how 3D photo-reconstruction and Structure from Motion (SfM) can be used to model channel evolution.

    The accepted rule for women contributing to nineteenth-century science before 1851 was that they could play only secondary roles in its production and authorship—as translators, illustrators, popularizers—and these by virtue of kinship or marriage to eminent scientists in the field or the laboratory. Sarah Bowdich (Lee) (1791–1856) presents an important amendment to this rule. As an explorer of West Africa on an equal scientific footing with her husband, and then a writer of science independently after his early death, she had other key roles as Georges Cuvier's cross-Channel scientific collaborator and as his first biographer. This article investigates and reframes Sarah's many individual achievements in science and its writing, to examine the larger questions of her case. How were her publications and ‘uneasy career’ in science possible? Can research on women in science today find inspiration in her example? PMID:26489182

For the purpose of this article, recent studies on the performative nature of emotions, which considered the central role of emotions such as pain, disgust and hatred in shaping the lives of individuals as well as the ways in which people relate to one another, were helpful in contemplating the situations of dehumanisation faced by both Sarah and Hagar as well as the broader question regarding upholding human worth in a context of indignity. This article furthermore considered the role of emotions in a conversation on ethics and particularly the way in which the narrative offered a fruitful avenue for considering Israel�s relationship to their neighbours � a line of interpretation that holds potential for reflecting on complex interracial and interethnic relationships in today�s global context.

  20. Rill erosion in burned and salvage logged western montane forests: Effects of logging equipment type, traffic level, and slash treatment

    Following wildfires, forest managers often consider salvage logging burned trees to recover monetary value of timber, reduce fuel loads, or to meet other objectives. Relatively little is known about the cumulative hydrologic effects of wildfire and subsequent timber harvest using logging equipment. We used controlled rill experiments in logged and unlogged (control) forests burned at high severity in northern Montana, eastern Washington, and southern British Columbia to quantify rill overland flow and sediment production rates (fluxes) after ground-based salvage logging. We tested different types of logging equipment-feller-bunchers, tracked and wheeled skidders, and wheeled forwarders-as well as traffic levels and the addition of slash to skid trails as a best management practice. Rill experiments were done at each location in the first year after the fire and repeated in subsequent years. Logging was completed in the first or second post-fire year. We found that ground-based logging using heavy equipment compacted soil, reduced soil water repellency, and reduced vegetation cover. Vegetation recovery rates were slower in most logged areas than the controls. Runoff rates were higher in the skidder and forwarder plots than their respective controls in the Montana and Washington sites in the year that logging occurred, and the difference in runoff between the skidder and control plots at the British Columbia site was nearly significant (p = 0.089). Most of the significant increases in runoff in the logged plots persisted for subsequent years. The type of skidder, the addition of slash, and the amount of forwarder traffic did not significantly affect the runoff rates. Across the three sites, rill sediment fluxes were 5-1900% greater in logged plots than the controls in the year of logging, and the increases were significant for all logging treatments except the low use forwarder trails. There was no difference in the first-year sediment fluxes between the feller

    Full Text Available Expression of the Down syndrome critical region 1 (DSCR1 protein, an inhibitor of the Ca2+-dependent phosphatase calcineurin, is elevated in the brains of individuals with Down syndrome (DS or Alzheimer's disease (AD. Although increased levels of DSCR1 were often observed to be deleterious to neuronal health, its beneficial effects against AD neuropathology have also been reported, and the roles of DSCR1 on the pathogenesis of AD remain controversial. Here, we investigated the role of sarah (sra; also known as nebula, a Drosophila DSCR1 ortholog, in amyloid-β42 (Aβ42-induced neurological phenotypes in Drosophila. We detected sra expression in the mushroom bodies of the fly brain, which are a center for learning and memory in flies. Moreover, similar to humans with AD, Aβ42-expressing flies showed increased Sra levels in the brain, demonstrating that the expression pattern of DSCR1 with regard to AD pathogenesis is conserved in Drosophila. Interestingly, overexpression of sra using the UAS-GAL4 system exacerbated the rough-eye phenotype, decreased survival rates and increased neuronal cell death in Aβ42-expressing flies, without modulating Aβ42 expression. Moreover, neuronal overexpression of sra in combination with Aβ42 dramatically reduced both locomotor activity and the adult lifespan of flies, whereas flies with overexpression of sra alone showed normal climbing ability, albeit with a slightly reduced lifespan. Similarly, treatment with chemical inhibitors of calcineurin, such as FK506 and cyclosporin A, or knockdown of calcineurin expression by RNA interference (RNAi, exacerbated the Aβ42-induced rough-eye phenotype. Furthermore, sra-overexpressing flies displayed significantly decreased mitochondrial DNA and ATP levels, as well as increased susceptibility to oxidative stress compared to that of control flies. Taken together, our results demonstrating that sra overexpression augments Aβ42 cytotoxicity in Drosophila suggest that DSCR1

    Gullies up to a few meters wide and up to one meter deep, as well as intermediate rather flat areas (so called inter-rill areas) are the two opposing characteristic surface features of the artificial research catchment 'Chicken Creek' in the vicinity of Cottbus (eastern Germany). They have emerged and intensified during the first five years of the ecosystem development. The present study aims at highlighting their hydrological functioning through a combination of in-situ and remote sensing of near-surface water content with numerical soil hydraulic modelling. A time series of more than one year of near-surface soil water contents was obtained from approximately thirty spatially distributed Decagon sensors at a depth of 10 to 15 cm, as well as from an L-band radiometer positioned on a 10-m high tower facing a footprint area in the research catchment of approximately 100 m2. They were used to verify a one-dimensional soil water and heat transfer model (COUP, Jansson and Karlberg, 2002) simulating surface runoff, infiltration and groundwater recharge for typical gully and inter-rill areas. The model was fed with detailed information about soil hydraulic properties and driven with hourly meteorological data. After calibration the numerical model correlated very well with the soil moisture measurements of the inter-rill areas (R2 = 0.68; root mean square error = 0.028 m3 m-3). This good agreement suggests that the chosen hydraulic properties of the uppermost soil layers are appropriate and that the simulated soil evaporation and snow dynamics are plausible. Also the much less dynamic soil water content in the gullies was reproduced well by the model. The seemingly appropriate simulation of the near-surface water dynamics, suggesting most of the precipitation to infiltrate and percolate to the groundwater, contradicts visual observations that surface runoff is the dominant runoff mechanism during rain storms. This unsolved discrepancy shall be further investigated in the

  6. Runoff experiment and adapted SfM photogrammetry to assess rill erosion in Mediterranean agricultural fields from a holistic point of view

    Science.gov (United States)

    Gronz, Oliver; Rodrigo-Comino, Jesús; Seeger, Manuel

    2017-04-01

    In Mediterranean agricultural fields, more research is needed to quantify soil loss and to assess runoff generation caused by unsuitable land management strategies (García-Díaz et al., 2017; Keesstra et al., 2016). Nowadays, farmers are increasing the generation of rills and, consequently, enhancing several sub-processes related to soil erosion by water such as headcut retreats, piping or cracks joint to mass movements (Marzolff and Poesen, 2009; Poesen et al., 2003; Rodrigo Comino et al., 2015). This complex problem under different spatiotemporal scales hinders a reliable forecasting of its final consequences (Prasuhn, 2011; Salome et al., 2014). Several researchers pay more attention to point observations, but no to general and connected overviews of processes related to forms and the quantitative functioning of all elements. Therefore, the main goal of this study is to characterize and quantify the rill erosion generated by these degradation processes. To achieve this goal, two runoff experiments were carried out with two repetitions (dry and wet conditions) under extreme conditions (Wirtz et al., 2013, 2012, 2010): a motor driven pump discharged a water inflow up to ˜4.2 l s-1 maintained during between 4 and 6 minutes (≈1000 litres). Additionally, a 3D-captation of the rill by an adapted SfM photogrammetry was performed to assess: i) clear visible zonation of geomorphological (structural) connectivity features; ii) runoff and sediment productions close to the catchment outlet under actual conditions; iii) topsoil-subsoil interaction and crusting crucial for runoff generation; and, iv) the area with evidence of (former) high erosion intensity now stable, but with remnant.

  8. The gendered embodiment of shame: Intersections of acquaintance rape, trauma and self-blame in Pompidou posse by Sarah Lotz

    Directory of Open Access Journals (Sweden)

    Jessica Murray

    2014-08-01

    Full Text Available This article offers a feminist literary analysis of the gendered embodiment of shame in Pompidou posse by Sarah Lotz. In this novel, Lotz depicts female characters who are sexually assaulted by acquaintances and the resultant shame and trauma reside in their bodies. I will demonstrate that the embodied shame of these characters is distinctly gendered and that this shapes their attempts to cope with the aftermath of the sexual assaults. A close reading of the text reveals that the characters are exposed to overwhelming social messages of female culpability in a larger context that is rife with misogyny. As a result, they anticipate blame to such an extent that they blame themselves and internalise this blame as shame. By focusing on the bodies of the survivors, Lotz demonstrates the embodiment of shame, but she also suggests a corporeal challenge to silencing. The bodies of these characters speak loudly, albeit sometimes in the halting language of trauma, and they function to alert them to danger, to help them excavate memories that are made inaccessible and to testify to traumatic sexual assault.

    The Polish-American scientist Ludwik Gross made two important discoveries in the early 1950s. He showed that two viruses - murine leukemia virus and parotid tumor virus - could cause cancer when they were injected into susceptible animals. At first, Gross's discoveries were greeted with skepticism: it seemed implausible that viruses could cause a disease as complex as cancer. Inspired by Gross's initial experiments, similar results were obtained by Sarah Stewart and Bernice Eddy who later renamed the parotid tumor virus SE polyoma virus after finding it could cause many different types of tumors in mice, hamsters, and rats. Eventually the "SE" was dropped and virologists adopted the name "polyoma virus." After Gross's work was published, additional viruses capable of causing solid tumors or blood-borne tumors in mice were described by Arnold Graffi, Charlotte Friend, John Moloney and others. By 1961, sufficient data had been accumulated for Gross to confidently publish an extensive monograph--Oncogenic Viruses--the first history of tumor virology, which became a standard reference work and marked the emergence of tumor virology as a distinct, legitimate field of study.

    坡耕地是紫色土区域典型的土地利用方式,细沟侵蚀是紫色土坡面侵蚀的主要形式之一.试验研究发现,10°,15°,20°,25°小区细沟侵蚀量占坡面总侵蚀量的比例分别为28.61%,57.66%,80.66%和91.16%;细沟沟头出现的顺坡临界坡长平均值分别为6.19m,4.15m,2.75m,1.57m.在大量野外调查的基础上,采用植物篱、“地埂十植物篱”和“大横坡十小顺坡”3种措施均能控制细沟侵蚀的发生.尤其是“大横坡十小顺坡”模式,兼具了植物篱与“地埂十植物篱”两种措施的优点,且造价低、节省劳力,具有较好的推广前景,特别是暂时无法实施坡改梯的广大偏远山区.%Rill erosion is one of the main erosion types on the purple soil slope cultivated land. It accounts for 28. 61%, 57. 66%, 80. 66% and 91. 16% when the slope gradients are 10°,15°,20°and 25°, respectively. Thereby, it is necessary to prevent rill initiation using appropriate measures in the interest of conserving soils. In the Five Years Development Project of Eleventh, some prevention and control measures were investigated by the research group of the slope cultivated land management in the Yangtze River area. In sum, the measures included hedgerows, "ridge + hedgerows" and "downslope ridge tillage and cross trenches". Among them, the key technology is to change the runoff flow direction on the critical length of rill initiation so as to prevent the rill erosion. The preliminary effect investigation shows some excellences in the environment and economy. The preferable estimation shows that these measures have advantages of operation and save inputs including investment and labor. Therefore, it is worth extending implemental areas, especially in the underdeveloped mountain regions.

    Sinuous rilles are the most easily recognizable small volcanic features on the moon, which can provide information on volcanic history and evolution of the moon. Lunar orbiter laser altimeter (LOLA) data were used in this paper to supplement Chang 'E CCD and lunar reconnaissance orbiter camera ( LROC ) images for making detailed observations of morphologic and topographic characteristics of sinuous rilles in Aristarchus region. Clementine images from three bands of the ultraviolet - visible camera were used to analyze the compositional properties of sinuous rille substrates below the pyroclastics. Topographic data lend support to the theory that sinuous rilles were formed by the thermal erosion of the basalt lava, the compositional property of sinuous rille substrates is the same, and the slope rather than the regional structural pattern is the dominant factor controlling the rille.%弯曲月溪是月球火山作用的产物,其形貌特征可以反映月海玄武岩的喷发历史和演化结果.基于最新高分辨率遥感月表图像和高精度DEM数据,分析月球Aristarchus地区弯曲月溪的形貌特征;结合Clementine UV/VIS多光谱图像的波段比值合成图像,分析月溪的物质成分.研究结果支持弯曲月溪的玄武岩熔岩流热侵蚀成因,表明研究区内的弯曲月溪具有相同的物源特征,月表坡度是控制月溪的主要因素.

    Recently, infrastructure construction developed rapidly and produced a large amount of engineering accumulation, which becomes a new critical point of soil and water loss. Particularly, rills formed quickly on the slope of engineering accumulation under high rainfall intensity and triggered intense soil erosion. Therefore, it is essential to study on the dynamic process of rill development and its impact on runoff and sediment yield. In this study, scouring-erosion experiments were conducted on steep slopes of engineering accumulation under different slope gradients (24°, 28° and 32°) with different flow discharge (5, 9, 13 and 17 L/min), simulating the surface runoff process under the rainfall intensity of 0.5, 1.0, 1.5 and 2.0 mm/min. The zonal soil type in test area is Heilu soil. The experimental plots were constructed in engineering excavated slope, meanwhile, soil parent material was the Loess of Malan at first and then turned into spoil derived from construction sites. The spoil here was sandy loam, with a soil-stone ratio more than 9:1 and the size of particles <1 mm. Each plot was 20 m long and 5 m wide, with 0.5 m deep soil layer and without vegetation. It was used to simulate the dumping engineering accumulation of gully region in loess plateau. According to the experiment design, runoff plot was divided into 5 one-meter-wide smaller plots by iron sheets, one of which was rebuilt as steps. To ensure the same original background, four rill experiment plots were backfilled and compacted after last experimental events. Because the randomness of the slope rill development may cause much difficulty on continuous observation, the slope surface was slightly concavely shaped to form a single rill. The morphological parameters such as rill width, rill depth, width-depth ratio and sectional area were selected to reveal the dynamic change of rill shape during erosion processes. The results showed: 1) The rill width and the rill depth both rapidly increased

    细沟径流输沙是细沟侵蚀产沙的重要过程,阐明细沟径流输沙与水动力学参数之间的关系可以有效地揭示细沟径流输沙的动力学机制,并为建立细沟侵蚀过程物理模型奠定基础.采用具有定流量人工放水的组合小区模拟降雨试验,研究黄土坡面细沟径流输沙对水动力学参数的响应关系.结果表明:1)一次降雨径流产生的细沟输沙模数对水动力学参数平均值响应关系大小顺序为平均水流断面单位能量(R=0.99)>平均水流功率(R=0.88)>平均水流切应力(R=0.82)>平均单位水流功率(R=0.76);2)降雨径流过程中,细沟输沙率对水动力学参数瞬时值响应关系为水流切应力(R=0.88)>水流功率(R=0.47),水流断面单位能量和单位水流功率的相关性较差,细沟输沙率对水流切应力的响应关系呈幂函数方程关系.%Runoff-induced sediment discharge is one of the most important process of erosion and sediment yield. It is important to clarify the relationships of runoff-induced sediment discharge and hydrodynamic parameters of rill flow on loess hillslope. In this paper, the relationships were studied by experiment of simulated rainfall and constant flow using group plots. Results showed that: 1 ) In single rainfall-runoff event, the response of sediment transport modulus to mean hydrodynamic parameters was given as follows: mean unit energy ( R = 0. 99) > mean stream power ( R = 0. 88) > mean stream shear stress ( R = 0. 82 ) > mean unit stream power ( R = 0. 76 ). 2) During the rainfall-runoff process, theresponse of the sediment transport rate to stream shear stress ( R = 0. 88) was greater than stream power ( R = 0. 47) , and the correlations of sediment transport rate with unit energy and with unit stream power were weak. The relationship of stream shear stress and the sediment transport rate could be expressed by power functions.

  18. From Shoestring Rills to Dendritic River Networks: Documenting the Evolution of River Basins Towards Geometric Similarity Through Divide Migration, Stream Capture and Lateral Branching

    Erosional river networks dissect much of Earth's surface into drainage basins. Global scaling laws such as Hack's Law suggest that river basins trend toward a particular scale-invariant shape. While erosional instabilities arising from competition between advective and diffusive processes can explain why headwaters branch, the erosional mechanics linking larger scale network branching with evolution towards a characteristic river basin shape remain poorly constrained. We map river steepness and a proxy for the steady-state elevation of river networks, χ, in simulated and real landscapes with a large range in spatial scale (102 -106 m) but with similar inclined, planar surfaces at the time of incipient network formation. We document that the evolution from narrow rill-like networks to dendritic, leaf-shaped river basins follows from drainage area differences between catchments. These serve as instabilities that grow, leading to divide migration, stream capture, lateral branching and network reorganization. As Horton hypothesized, incipient networks formed down gradient on an inclined, planar surface have an unequal distribution of drainage area and nonuniformity in response times such that larger basins erode more rapidly and branch laterally via capture of adjacent streams with lower erosion rates. Positive feedback owing to increase in drainage area furthers the process of branching at the expense of neighboring rivers. We show that drainage area exchange and the degree of network reorganization has a significant effect on river steepness in the Dragon's Back Pressure Ridge, CA, the Sierra Nevada, CA, and the Rocky Mountain High Plains, USA. Similarly, metrics of basin shape reveal that basins are evolving from narrow basins towards more common leaf shapes. Our results suggest that divide migration and stream capture driven by erosional disequilibrium could be fundamental processes by which river basins reach their characteristic geometry and dendritic form.

    The aim of this study was to improve the existing knowledge of the runoff and inter-rill erosion response of forest stands following wildfire, focusing on commercial eucalypt plantations and employing field rainfall simulation experiments (RSE's). Repeated RSE's were carried out in two adjacent but contrasting eucalypt stands on steep hill slopes in north-central Portugal that suffered a moderate severity fire in July 2005. This was done at six occasions ranging from 3 to 24 months after the fire and using a paired-plot experimental design that comprised two pairs of RSE's at each site and occasion. Of the 46 RSE's: (i) 24 and 22 RSE's involved application rates of 45-50 and 80-85 mm h(-1), respectively; (ii) 22 took place in a stand that had been ploughed in down slope direction several years before the wildfire and 24 in an unploughed stand. The results showed a clear tendency for extreme-intensity RSE's to produce higher runoff amounts and greater soil and organic matter losses than the simultaneous high-intensity RSE's on the neighbouring plots. However, there existed marked exceptions, both in space (for one of the plot pairs) and time (under intermediate soil water repellency conditions). Also, overland flow generation and erosion varied significantly between the various field campaigns. This temporal pattern markedly differed from a straightforward decline with time-after-fire and rather suggested a seasonal component, reflecting broad variations in topsoil water repellency. The ploughed site produced less runoff and erosion than the unploughed site, contrary to what would be expected if the down slope ploughing had occurred after the wildfire instead of several years before it. Finally, sediment losses at both study sites were noticeably lower than those reported by other studies involving repeat RSE's, i.e. in Australia and western Spain. This possibly reflected a history of intensive land use in the study region, including in more recent times after the

    Full Text Available Germany has seen a recent upsurge in publications proclaiming that feminism is again an urgent matter for a new generation of women. Faced with the reactionary demography debate and the hegemony of second-wave feminism, young writers, musicians, journalists, and critics call for new models of feminism relevant to women today. As one of these viable models, popfeminism draws on dominant trends in mass culture, on pop’s forty-year history as a cultural prefix in Germany, and on traditional feminism in order to create a new, ostensibly apolitical, feminist subculture based in self-stylization and individual autonomy. Shared by many popfeminist sources is the depiction of negatively coded female corporeality. This article begins with a theoretical analysis of writings on sexuality and the body in recent (popfeminist nonfiction. It then examines the negative corporeal self-stylizations in Turkish-German rapper Lady Bitch Ray’s performances since 2006, in former music video host Charlotte Roche’s novel Feuchtgebiete (2008, and in media personality Sarah Kuttner’s novel Mängelexemplar (2009. Ultimately, these negatively coded bodies are shown to uncover popfeminism’s political intent.

Os objetivos deste trabalho foram: avaliar as condições hidráulicas do escoamento em sulcos de erosão, que podem fornecer subsídios importantes às relações de erosão, e determinar as taxas de desagregação do solo, a erodibilidade do solo e a tensão crítica de cisalhamento, além de quantificar o transporte de sedimentos em sulcos por meio de expressões baseadas em variáveis hidráulicas. Para tanto, sulcos foram pré-formados em um solo de textura franco-argilo-arenosa, num campo com declive médio de 0,067 m m-1, e submetidos à aplicação de chuva simulada com intensidade de 74 mm h-1, durante 80 min, tendo sido aplicados nos sulcos, nos últimos 20 min, fluxos extras de escoamento superficial de 0, 10, 20, 30, 40 e 50 L min-1. Os resultados mostraram que o regime de escoamento nos sulcos caracterizou-se como sendo de transição subcrítico a turbulento subcrítico.

    Full Text Available Abstract Background Rheumatoid Arthritis (RA commonly affects the hands and wrists with inflammation, deformity, pain, weakness and restricted mobility leading to reduced function. The effectiveness of exercise for RA hands is uncertain, although evidence from small scale studies is promising. The Strengthening And Stretching for Rheumatoid Arthritis of the Hand (SARAH trial is a pragmatic, multi-centre randomised controlled trial evaluating the clinical and cost effectiveness of adding an optimised exercise programme for hands and upper limbs to best practice usual care for patients with RA. Methods/design 480 participants with problematic RA hands will be recruited through 17 NHS trusts. Treatments will be provided by physiotherapists and occupational therapists. Participants will be individually randomised to receive either best practice usual care (joint protection advice, general exercise advice, functional splinting and assistive devices or best practice usual care supplemented with an individualised exercise programme of strengthening and stretching exercises. The study assessors will be blinded to treatment allocation and will follow participants up at four and 12 months. The primary outcome measure is the Hand function subscale of the Michigan Hand Outcome Questionnaire, and secondary outcomes include hand and wrist impairment measures, quality of life, and resource use. Economic and qualitative studies will also be carried out in parallel. Discussion This paper describes the design and development of a trial protocol of a complex intervention study based in therapy out-patient departments. The findings will provide evidence to support or refute the use of an optimised exercise programme for RA of the hand in addition to best practice usual care.

  5. “A horror so deep only ritual can contain it”: The art of dying in the theatre of Sarah Kane

    Directory of Open Access Journals (Sweden)

    Sara Soncini

    2010-10-01

    Full Text Available Death is an overarching presence in Sarah Kane's dramatic universe, peopled by characters charging towards death, and usually encountering it in scenes of Grand Guignol excess and grotesque violence. Death is ambivalently presented as the only escape from the nightmare of living and, at the same time, as that which makes living a nightmare; as the moment of "complete sanity and humanity" in which "everything suddenly connects", and as the ultimate, irrevocable and unredeemable act of self-annihilation. Following Kane's turn towards a more poetic form of drama, in her last two plays this discourse of death is handed over to the words nameless characters or unidentified voices who are likewise engaged in a long, painful quest for selfhood pivoting on the awareness of mortality and the simultaneous dread of and longing for death it engenders. This essay focuses on the ritual quality of the death scenes and/or narratives that crowd Kane's drama. Throughout her work, dying is never an easy, straightforward business, but rather a long, complicated, and at times frustrating mise en scène which also entails rehearsing a repertory of traditional rituals and, once their shortcomings become apparent, devising and testing new ones. The amount of theatricality involved in the art of dying is foregrounded through a web of intertextual references to other literary and/or dramatic sources; this dialogue ties in with a self-reflexive probing of the theatre's ability to provide a ritual that will be capable of "contain[ing] the horror" by supplying a formal framework to express, embody and experience death collectively.

    Background Untreated advanced hepatocellular carcinoma (HCC) has an overall poor prognosis. Currently there are 2 ongoing prospective randomized controlled trials that are evaluating the efficacy and safety of sorafenib and selective internal radiation therapy (SIRT) with yttrium-90 resin microspheres in patients with advanced HCC. The SorAfenib versus Radioembolisation in Advanced Hepatocellular carcinoma (SARAH; 459 patients) trial is being performed in Europe and the SIRt VErsus SorafeNIB (SIRveNIB; 360 patients) trial in the Asia Pacific region. Prospectively combining the results, these trials will not only allow for increased precision to estimate efficacy (in terms of survival), but will also provide increased statistical power for subgroup analyses. Objective To ensure the prospectivity and transparency of the meta-analysis. Methods The sirVEnib and SARAH merge PROject (VESPRO) is an individual, patient-data prospective meta-analysis of the SIRveNIB and SARAH randomized trials. The VESPRO protocol includes prespecified hypotheses, inclusion criteria, and outcome measures. The primary outcome measure is overall survival and secondary outcomes include tumor response rate, progression-free survival, progression in the liver as first event, and disease control in the liver. Pooling of toxicity results will allow for robust safety profiles to be established for both therapies, and provides increased statistical power to investigate treatment effects in key subgroups. Analyses will be performed in the intent-to-treat population stratified by trial. Results Both studies are expected to demonstrate a survival benefit for SIRT together with a better toxicity profile compared with sorafenib. It is also anticipated that liver progression as the first event would be longer in the intervention compared with the control. Conclusions As the results of the 2 trials are not yet known, the methodological strength is enhanced, as biases inherent in conventional meta

Prospectively combining the results, these trials will not only allow for increased precision to estimate efficacy (in terms of survival), but will also provide increased statistical power for subgroup analyses. To ensure the prospectivity and transparency of the meta-analysis. The sirVEnib and SARAH merge PROject (VESPRO) is an individual, patient-data prospective meta-analysis of the SIRveNIB and SARAH randomized trials. The VESPRO protocol includes prespecified hypotheses, inclusion criteria, and outcome measures. The primary outcome measure is overall survival and secondary outcomes include tumor response rate, progression-free survival, progression in the liver as first event, and disease control in the liver. Pooling of toxicity results will allow for robust safety profiles to be established for both therapies, and provides increased statistical power to investigate treatment effects in key subgroups. Analyses will be performed in the intent-to-treat population stratified by trial. Both studies are expected to demonstrate a survival benefit for SIRT together with a better toxicity profile compared with sorafenib. It is also anticipated that liver progression as the first event would be longer in the intervention compared with the control. As the results of the 2 trials are not yet known, the methodological strength is enhanced, as biases inherent in conventional meta-analyses are avoided. This has the effect of providing

Over the years, about seven of my female trainees have ended up working at the practice with me. So I certainly think I must have been doing something right. “I would very much say to a woman going into medicine today, you can do absolutely everything that a man can do. Some women do take time out to have babies that does not make you a second class citizen and it absolutely does not mean, by any means, that you can’t do everything that you want to do. You should, just maybe not do it all at once. It depends on the person.” .......

    This paper sets out from the oriental Buddhism and Zen′s thought to re-interpret the character image of Sarah,one from The French Lieutenant′s Woman.It starts from analyzing her close relationship with nature to link her image to Buddhism and Zen′s thought.Then it analyzes her image of a Buddhist "suffering masses"and "assis-ting and enlightening sage".Sarah represents the suffering mass and she has the personality of helping others out of distress.In the last two endings of this novel,Zen′s beliefs of "impermanence"and "life or death detachment"are shadowed from the choice she makes.Her choice in the third ending is a kind of spiritual detachment and self-satis-faction representing her supreme ideological level of Buddhism and Zen′s thought.%从东方佛禅思想入手,重新解读《法国中尉的女人》中莎拉的人物形象。通过分析她与自然的紧密联系,构建她与佛禅的关系,进而指出她所折射出的佛家“受苦受难的众生”形象和“普度众生的圣僧”形象。莎拉身上有受苦大众的影子,也有救苦救难的济世者特质。她在小说后两种结局里的命运折射出了禅宗“诸行无常”和“超脱生死”的观念。她在第三种结局里的选择反映了其精神上的超脱和自我满足,达到了佛禅思想的至高境界。

  15. Structural Transformation and Historical Expression in Dynastic Legend of Early China---Review of Sarah Allan’s Study on the Ancient Legends of China in The Heir and The Sage

    Yang Jie; Zhang Yuan

    2016-01-01

    As an important scholar of contem-porary sinology, Sarah Allan’s research on Chinese ancient history, on the basis of continuing the tra-dition of historical studies and archaeology, used Claude Lévi-Strauss’ theory and method of struc-turalism for reference, and opened a new path for western Sinological research. Her study of ancient legends initiated wide interest in the circles of si-nology, and was considered to be both special and very innovative. In her masterpiece The Heir and the Sage: Dynastic Legend in Early China, Allan used a method for analyzing mythology which is transformed from anthropological structuralism. She made an in-depth and systematic research on the dynastic legends from the legendary period of Tang Yao to the periods of Yin and Zhou which were recorded in the classical literature of the pre-Qin period, and discussed heuristically the his-torical perception, structure characteristics of the expressions, as well as the values of the subject in the legendary records. By summarizing the theoret-ical logic and main ideas of The Heir and the Sage, this article attempts to open a preliminary discus-sion on how to promote anthropological research on the legendary period of early China using the meth-odology of structuralism. In her Sinological re-search works which are dedicated to the study of the legendary period of ancient China, such as The Heir and the Sage: Dynastic Legend in Early Chi-na,The Shape of the Turtle:Myth ,Art and Cosmos in Early China, and The Way of Water and Sprouts of Virtue:Root Metaphor in Early Chinese Philo-sophical Thought, Allan has tried to use the meth-odology of structuralism to analyze the historical expressions and ideas contained in ancient Chinese literature. In so doing, she is seeking to re -ex-plain the historical consciousness and philosophy of ancient China. It could be said that Allan’s Sino-logical research has pronounced anthropological features concerning her problems, consciousness, and

This detector unit shows that silicon detectors for nuclear physics particle detection were already developed and in use in the 1960's in Amsterdam. Also the idea of putting 'strips' onto the silicon for high spatial resolution of a particle's impact on the detector were implemented in the BOL project which used 64 of these detector units. The IKO BOL project with its silicon particle detectors was designed, built and operated from 1965 to roughly 1977. Detector Unit of the BOL project: These detectors, notably the ‘checkerboard detector’, were developed during the years 1964-1968 in Amsterdam, The Netherlands, by the Natuurkundig Laboratorium of the N.V. Philips Gloeilampen Fabrieken. This was done in close collaboration with the Instituut voor Kernfysisch Onderzoek (IKO) where the read-out electronics for their use in the BOL Project was developed and produced.

    Full Text Available This paper presents and discusses an integrated set of policies designed to reduce U.S. carbon emissions over the next four decades. This innovation path also aims to promote environmental quality, particularly by reducing emissions of criteria air pollutants, to reduce U.S. dependence on imported oil, and to induce technological innovation and diffusion in energy production and consumption. The innovation path would reduce economy-wide carbon emissions by 26% below baseline projections for 2010 and by 62% below baseline projections for 2030; this translates into 10% below 1990 levels in 2010 and 45% below 1990 levels in 2030. Emissions of criteria pollutants also would be significantly reduced, as would petroleum imports by the United States. Moreover, the innovation path would yield cumulative net savings for the United States of $218 billion (1993 dollars through 2010, or $19 billion on a leveled annual basis, and would result in 800,000 additional jobs nationwide by 2010. Although the overall findings from the innovation path analysis are robust, the results should be taken as indicative, rather than precisely predictive, owing to uncertainties in future costs, prices, technology performance, and consumer behavior.

In the United Arab Emirates, a country where the rate of obesity is dramatically increasing bariatric surgery has gained popularity in recent years; however, published data on its outcomes in the Emirati population are lacking.Methods: We retrospectively reviewed the medical records of 95 patients who underwent bariatric surgery (ie, laparoscopic Roux-en-Y gastric bypass [RYGB] or laparoscopic sleeve gastrectomy at the Rashid Center for Diabetes and Research in Ajman, United Arab Emirates. Weight outcomes and metabolic marker data were abstracted at baseline and at 3, 6, and 12 months postoperatively.Results: Laparoscopic RYGB was the main procedure performed by our bariatric unit. All variables demonstrated postoperative improvement. An average excess weight loss of 68% was observed at 12 months. Fat mass was the body component that decreased the most, with an average reduction of 46%. Additionally, lipid profiles were significantly different (P<0.01 at 12 months, with triglyceride levels improving by 27% and low-density lipoprotein levels improving by 21%. Similarly, glycated hemoglobin (HbA1c levels decreased significantly (P<0.001 in patients with type 2 diabetes, with an average reduction of 73%.Conclusion: Our results show that a substantial short-term reduction in weight and significant improvements in metabolic markers followed bariatric surgery in severely obese Emirati patients. Our results are consistent with the outcomes of other internationally published studies. Additional studies are warranted to determine whether

    The concepts of animal units, animal unit months, and animal unit equivalents have long been used as standards for range management planning, estimating stocking rates, reporting actual use, assessing grazing fees, ranch appraisal, and other purposes. Increasing size of cattle on rangelands has led some to suggest that the definition of animal units and animal unit...

  15. Voltage verification unit

    Science.gov (United States)

    Martin, Edward J.

    2008-01-15

    A voltage verification unit and method for determining the absence of potentially dangerous potentials within a power supply enclosure without Mode 2 work is disclosed. With this device and method, a qualified worker, following a relatively simple protocol that involves a function test (hot, cold, hot) of the voltage verification unit before Lock Out/Tag Out and, and once the Lock Out/Tag Out is completed, testing or "trying" by simply reading a display on the voltage verification unit can be accomplished without exposure of the operator to the interior of the voltage supply enclosure. According to a preferred embodiment, the voltage verification unit includes test leads to allow diagnostics with other meters, without the necessity of accessing potentially dangerous bus bars or the like.

  1. Dimensionless Units in the SI

    CERN Document Server

    Mohr, Peter J

    2014-01-01

    The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no additional numerical factor. Here we consider dimensionless units as defined in the SI, {\\it e.g.} angular units like radians or steradians and counting units like radioactive decays or molecules. We show that an incoherence may arise when different units of this type are replaced by a single dimensionless unit, the unit "one", and suggest how to properly include such units into the SI in order to remove the incoherence. In particular, we argue that the radian is the appropriate coherent unit for angles and that hertz is not a coherent unit in the SI. We also discuss how including angular and counting units affects the fundamental constants.

  2. Battery thermal management unit

    Science.gov (United States)

    Sanders, Nicholas A.

    1989-03-01

    A battery warming device has been designed which uses waste heat from an operating internal combustion engine to warm a battery. A portion of the waste heat is stored in the sensible and latent heat of a phase change type material for use in maintaining the battery temperature after the engine is shut off. The basic design of the device consists of a Phase Change Material (PCM) reservoir and a simple heat exchanger connected to the engineer's cooling system. Two types of units were built, tested and field trialed. A strap-on type which was strapped to the side of an automotive battery and was intended for the automotive after-market and a tray type on which a battery or batteries sat. This unit was intended for the heavy duty truck market. It was determined that both types of units increased the average cranking power of the batteries they were applied to. Although there were several design problems with the units such as the need for an automatic thermostatically controlled bypass valve, the overall feeling is that there is a market opportunity for both the strap-on and tray type battery warming units.

  3. Coherence for weak units

    CERN Document Server

    Joyal, André

    2009-01-01

    We define weak units in a semi-monoidal 2-category $\\CC$ as cancellable pseudo-idempotents: they are pairs $(I,\\alpha)$ where $I$ is an object such that tensoring with $I$ from either side constitutes a biequivalence of $\\CC$, and $\\alpha: I \\tensor I \\to I$ is an equivalence in $\\CC$. We show that this notion of weak unit has coherence built in: Theorem A: $\\alpha$ has a canonical associator 2-cell, which automatically satisfies the pentagon equation. Theorem B: every morphism of weak units is automatically compatible with those associators. Theorem C: the 2-category of weak units is contractible if non-empty. Finally we show (Theorem E) that the notion of weak unit is equivalent to the notion obtained from the definition of tricategory: $\\alpha$ alone induces the whole family of left and right maps (indexed by the objects), as well as the whole family of Kelly 2-cells (one for each pair of objects), satisfying the relevant coherence axioms.

  4. Dispersion in unit disks

    CERN Document Server

    Dumitrescu, Adrian

    2009-01-01

    We present two new approximation algorithms with (improved) constant ratios for selecting $n$ points in $n$ unit disks such that the minimum pairwise distance among the points is maximized. (I) A very simple $O(n \\log{n})$-time algorithm with ratio 0.5110 for disjoint unit disks. In combination with an algorithm of Cabello \\cite{Ca07}, it yields a $O(n^2)$-time algorithm with ratio of 0.4487 for dispersion in $n$ not necessarily disjoint unit disks. (II) A more sophisticated LP-based algorithm with ratio 0.6495 for disjoint unit disks that uses a linear number of variables and constraints, and runs in polynomial time. The algorithm introduces a novel technique which combines linear programming and projections for approximating distances. The previous best approximation ratio for disjoint unit disks was 1/2. Our results give a partial answer to an open question raised by Cabello \\cite{Ca07}, who asked whether 1/2 could be improved.

  5. Signal processing unit

    Energy Technology Data Exchange (ETDEWEB)

    Boswell, J.

    1983-01-01

    The architecture of the signal processing unit (SPU) comprises an ROM connected to a program bus, and an input-output bus connected to a data bus and register through a pipeline multiplier accumulator (pmac) and a pipeline arithmetic logic unit (palu), each associated with a random access memory (ram1,2). The system pulse frequency is from 20 mhz. The pmac is further detailed, and has a capability of 20 mega operations per second. There is also a block diagram for the palu, showing interconnections between the register block (rbl), separator for bus (bs), register (reg), shifter (sh) and combination unit. The first and second rams have formats 64*16 and 32*32 bits, respectively. Further data are a 5-v power supply and 2.5 micron n-channel silicon gate mos technology with about 50000 transistors.

We focus on the natural multi-unit analogue of the first-price auction, where buyers bid total payments, pay their bids, and where the seller allocates goods to maximize his...... revenue. While there are many equilibria in this auction, only efficient equilibria remain when the truthful equilibrium restriction of the menu-auction literature is used.

    A color recording unit was designed for output and control of digitized picture data within computer controlled reproduction and picture processing systems. In order to get a color proof picture of high quality similar to a color print, together with reduced time and material consumption, a photographic color film material was exposed pixelwise by modulated laser beams of three wavelengths for red, green and blue light. Components of different manufacturers for lasers, acousto-optic modulators and polygon mirrors were tested, also different recording methods as (continuous tone mode or screened mode and with a drum or flatbed recording principle). Besides the application for the graphic arts - the proof recorder CPR 403 with continuous tone color recording with a drum scanner - such a color hardcopy peripheral unit with large picture formats and high resolution can be used in medicine, communication, and satellite picture processing.

    Full Text Available Subject of Research. The results of lidar combined scanning unit development for locating leaks of hydrocarbons are presented The unit enables to perform high-speed scanning of the investigated space in wide and narrow angle fields. Method. Scanning in a wide angular field is produced by one-line scanning path by means of the movable aluminum mirror with a frequency of 20Hz and amplitude of 20 degrees of swing. Narrowband scanning is performed along a spiral path by the deflector. The deflection of the beam is done by rotation of the optical wedges forming part of the deflector at an angle of ±50. The control function of the scanning node is performed by a specialized software product written in C# programming language. Main Results. This scanning unit allows scanning the investigated area at a distance of 50-100 m with spatial resolution at the level of 3 cm. The positioning accuracy of the laser beam in space is 15'. The developed scanning unit gives the possibility to browse the entire investigated area for the time not more than 1 ms at a rotation frequency of each wedge from 50 to 200 Hz. The problem of unambiguous definition of the beam geographical coordinates in space is solved at the software level according to the rotation angles of the mirrors and optical wedges. Lidar system coordinates are determined by means of GPS. Practical Relevance. Development results open the possibility for increasing the spatial resolution of scanning systems of a wide range of lidars and can provide high positioning accuracy of the laser beam in space.

    The gear, vane and piston pumps occupy a more then 90% share in the hydraulic pumps. Comparatively large pumps are mainly variable delivery piston pumps. The piston pumps are comparatively high in output density (output per unit weight), indicating the hydraulic pump in performance, and tend to become higher and higher in it. Though they are mainly 210 to 350kgf/cm/sup 2/ in rated pressure, some of them come to surpass 400kgf/cm/sup 3/ in it. While the progress in computation also requires the high speed operation, high accuracy and other severe conditions for the hydraulic units, which accordingly and increasingly intensify the requirement for hydraulic oil in abrasion resistibility, oxidation stability and response characteristics. While cavitation comes to easily occur, which considerably and disadvantageously influences hydraulic oil in life through degradation, noise level and respondingness. From now on, the development of high performance oil and study of mechanical structure are important. 19 references, 9 figures, 2 tables.

    A good dozen different targets are available for ISOLDE, made of different materials and equipped with different kinds of ion-sources, according to the needs of the experiments. Each separator (GPS: general purpose; HRS: high resolution) has its own target. Because of the high radiation levels, robots effect the target changes, about 80 times per year. In the standard unit shown in picture _01, the target is the cylindrical object in the front. It contains uranium-carbide kept at a temperature of 2200 deg C, necessary for the isotopes to be able to escape. At either end, one sees the heater current leads, carrying 700 A. The Booster beam, some 3E13 protons per pulse, enters the target from left. The evaporated isotope atoms enter a hot-plasma ion source (the black object behind the target). The whole unit sits at 60 kV potential (pulsed in synchronism with the arrival of the Booster beam) which accelerates the ions (away from the viewer) towards one of the 2 separators.

    This discussion of the United Arab Emirates focuses on the following: the people; geography; history; government; political conditions; defense; the economy; foreign relations; and relations between the US and the United Arab Emirates. In 1983 the population was estimated at 1,194,000. In 1984 the annual growth rate was negative. Life expectancy is about 60 years. Fewer than 20% of the population are UAE citizens. Indigenous Emiris are Arab; the rest of the population includes significant numbers of other Arabs -- Palestinians, Egyptians, Jordanians, Yemenis, Omanis, as well as many Iranians, Pakistanis, Indians, and West Europeans, especially in Dubai. The UAE is in the eastern Arabian Peninsula, bounded on the north by the Persian Gulf. European and Arab pirates roamed the Trucial Coast area from the 17th century into the 19th century. Early British expeditions against the pirates led to further campaigns against their headquarters. Piracy continued intermittently until 1835, when the shaikhs agreed not to engage in hostilities at sea. Primarily in reaction to the ambitions of other European countries, the UK and the Trucial States established closer bonds in an 1892 treaty. In 1968 the British government announced its decision, reaffirmed in March 1971, to end the treaty relationship with the gulf shaikhdoms. When the British protective treaty with the Trucial Shaikhdoms ended on December 1, they became fully independent. On December 2, 1971, 6 of them entered into a union called the United Arab Emirates. The 7th, Ras al-Khaimah, joined in early 1972. Administratively, the UAE is a loose federation of 7 emirates, each with its own ruler. The pace at which local government in each emirate is evolving, from traditional to modern, is set primarily by the ruler. Under the provisional constitution of 1971, each emirate reserves considerable powers, including control over mineral rights, taxation, and police powers. In this milieu, the growth of federal powers has

    Learning unit: Thin lenses "Why objects seen through lenses are sometimes upright and sometimes reversed" Nita Laura Simona National College of Arts and Crafts "Constantin Brancusi", Craiova, Romania 1. GEOMETRIC OPTICS. 13 hours Introduction (models, axioms, principles, conventions) 1. Thin lenses (Types of lenses. Defining elements. Path of light rays through lenses. Image formation. Required physical quantities. Lens formulas). 2. Lens systems (Non-collated lenses. Focalless systems). 3. Human eye (Functioning as an optical system. Sight defects and their corrections). 4. Optical instruments (Characteristics exemplified by a magnifying glass. Paths of light rays through a simplified photo camera. Path of light rays through a classical microscope) (Physics curriculum for the IXth grade/ 2011). This scenario exposes a learning unit based on experimental sequences (defining specific competencies), as a succession of lessons started by noticing a problem whose solution assumes the setup of an experiment under laboratory conditions. Progressive learning of theme objectives are realised with sequential experimental steps. The central cognitive process is the induction or the generalization (development of new knowledge based on observation of examples or counterexamples of the concept to be learnt). Pupil interest in theme objectives is triggered by problem-situations, for example: "In order to better see small objects I need a magnifying glass. But when using a magnifier, small object images are sometimes seen upright and sometimes seen reversed!"

    I am writing with regard to Kevin McGuigan's definition of the darwin unit, Dw, as "the mathematical probability of one undergraduate (or faculty) fatality per practical if the person in question is left to their own devices" (July p60). Although it is clear how the loss of genitals in a laboratory accident would result in a student's removal from the gene pool, McGuigan does not explain how the loss of finger (a 1 mDw event, he suggests) might impede procreation in the slightest. Perhaps McGuigan is confusing Darwin's evolution by natural selection with Lamarck's discredited theory of evolution by the inheritance of acquired characteristics. If so, the gulf between physicists and biologists seems as wide as ever.

  16. Preliminary results of geologic and remote sensing studies of Rima Mozart

    1987-01-01

    In order to better understand the processes responsible for the formation of lunar sinuous rilles, a study of Rima Mozart was conducted using a variety of geologic, photographic, and remote sensing data. The apparent source of this rille is located in a highlands unit of known composition and it is hypothesized that thermal and mechanical erosion played an important role in the formation of Rima Mozart. Excellent photographic, topographic, multispectral, and radar data exist for this rille. The preliminary results of an analysis of this data are presented. Photographic data indicates the presence of two volcanic source vents for Rima Mozart: Kathleen and Ann. It is suggested that Rima Mozart, like many other lunar sinuous rilles, was most likely formed by a combination of events. Rima Mozart does follow a pre-existing, dominant NW/SE structural trend suggesting the influence of structural features on the rille, however, the tectonic influence is not the sole source for the formation of the rille, as suggested by the presence of the two source vents and the spatter around Ann. It is suggested that the rille formation began with an explosive eruption at Kathleen which later calmed down to a pulsating, high volume, low-viscosity lava flow. The rapid effusion rate of the magma as well as its high temperature and turbid nature helped carve the sinuous rille into the fractured and structurally weak Apennine Bench Formation underneath. Similar eruptions and subsequent flows were also created at Ann and joined to the main channel by a NE-trending secondary rille.

  17. Relationships between slope erosion processes and aggregate stability of Ultisols from subtropical China during rainstorms

    Soil aggregates, being a key soil structural unit, influence several soil physical properties such as water infiltration, runoff and erosion. The relationship between soil aggregate stability and interrill and rill erodibility is unclear but critical to process-based erosion prediction models. One obvious reason is that it is hard to distinguish between interrill and rill-eroded sediment during the erosion process. This study was designed to partition interrill and rill erosion rates and relates them to the aggregate stability of Ultisols in subtropical China. Six kinds of rare earth element (REE) were applied as tracers mixed with two cultivated soils derived from the Quaternary red clay soil and the shale soil at six slope positions. Soil aggregate stability was determined by the Le Bissonnais (LB)-method. Simulated rainfall with three intensities (60, 90 and 120 mm/h) were applied to a soil plot (2.25 m long, 0.5 m wide, 0.2 m deep) at three slope gradients (10°, 20° and 30°) with duration of 30 min after runoff initiation. The results indicated that interrill and rill erosion increased with increasing rainfall intensity and slope gradient for both types of soil. Rill and interrill erosion rates of the shale soil were much higher than those of the Quaternary red clay soil. Rill erosion contribution enhanced with increasing rainfall intensity and slope gradient for both soils. Percentage of the downslope area erosion to total erosion was the largest, followed by the mid-slope area and then upslope area. Equations using an aggregate stability index As to replace the erodibility factor of interrill and rill erosion in the Water Erosion Prediction Project (WEPP) model were constructed after analyzing the relationships between estimated and measured rill and interrill erosion data. It was shown that these equations based on the stability index, As, have the potential to improve methods for assessing interrill and rill erosion erodibility synchronously for the

    In attempts to develop a means of life prolongation the humankind has created more than three hundred theories of the aging; each of them offers the original cause of aging. However, none of them has given practical result by now. The majority of the theories have now only historical interest. There are several different theories that are mainly under consideration currently. They are based on reliable, proven evidence: the free radical theory, the protein error theory, the replicative senescence theory, the theory of reparation weakening, the immunological theory, several versions of neuroendocrinal theories, and programmed aging theory. The theory presented here is based on conception that the life as the phenomenon represents many of the interconnected physical and chemical processes propelled by energy of the mitochondrial bioenergetical machine. Gradual degradation of all vital processes is caused by the programmed decrease in level of bioenergetics. This theory unites all existing theories of aging constructed on authentic facts: it is shown, that such fundamental phenomena accompanying aging process as the increase in level of reactive oxygen species (ROS), the decrease in the general level of protein synthesis, the limitation of cellular dividing (Haiflick limit), decrease in efficiency of reparation mechanisms are caused by bioenergetics attenuation. Each of these phenomena in turn generates a number of harmful secondary processes. Any of the theories bases on one of these destructive phenomena or their combination. Hence, each of them describes one of sides of process of the aging initially caused by programmed decrease of level of bioenergetics. This united theory gives the chance to understand the nature of aging clock and explains a phenomenon of increase in longevity at the condition of food restriction. Failures of attempts to develop means from aging are explained by that the manipulations with the separate secondary phenomena of attenuation of

    Measures of temperature that center around human experience get lots of use. Of course thermal physics insights of the last century have shown that reciprocal temperature (1/kT) has applications that temperature addresses less well. In addition to taking on negative absolute values under population inversion (e.g. of magnetic spins), bits and bytes turn 1/kT into an informatic measure of the thermal ambient for developing correlations within any complex system. We show here that, in the human-friendly units of bytes and food Calories, water freezes when 1/kT ~200 ZB/Cal or kT ~5 Cal/YB. Casting familiar benchmarks into these terms shows that habitable human space requires coldness values (part of the time, at least) between 0 and 40 ZB/Cal with respect body temperature ~100 degrees F, a range in kT of ~1 Cal/YB. Insight into these physical quantities underlying thermal equilibration may prove useful for budding scientists, as well as the general public, in years ahead.

    This paper is aimed at presenting what is already a reality in TRANSPETRO in the area covered by OSBRA, a pipeline that carries by-products to the Mid-West region of Brazil. In order to meet the needs of covering occasional accidents, TRANSPETRO counts on a standardized system of emergency management. It is a great challenge to secure an efficient communication along the 964 km of extension, considering that there are shadow zones where it is not possible to use conventional means of communication such as mobile telephony and internet. It was in this context that the Mobile Contingency Unit Via Satellite - MCU was developed, to extend the communication facilities existing in fixed installations to remote places, mainly the pipeline right of ways. In case of emergency, simulation and work in the pipeline right of way, MCU is fully able to provide the same data, voice, closed-circuit TV and satellite video conference facilities that are available in any internal area of the PETROBRAS system.

    The Mission Operations Lab initiated a project to design, develop, deliver, test, and validate a unique training system for astronaut and ground support personnel. In an effort to keep training costs low, virtual training units (VTUs) have been designed based on images of actual hardware and manipulated by a touch screen style interface for ground support personnel training. This project helped modernized the training system and materials by integrating them with mobile devices for training when operators or crew are unavailable to physically train in the facility. This project also tested the concept of a handheld remote device to control integrated trainers using International Space Station (ISS) training simulators as a platform. The portable VTU can interface with the full-sized VTU, allowing a trainer co-located with a trainee to remotely manipulate a VTU and evaluate a trainee's response. This project helped determine if it is useful, cost effective, and beneficial for the instructor to have a portable handheld device to control the behavior of the models during training. This project has advanced NASA Marshall Space Flight Center's (MSFC's) VTU capabilities with modern and relevant technology to support space flight training needs of today and tomorrow.

    Samuel Pozzi was a major figure in the early development of modern gynaecological surgery. His textbook, A Treatise on Gynaecology, published in French in 1890 and rapidly translated into five other languages, was the first internationally acclaimed text integrating modern principles of anaesthesia, antisepsis, diagnosis, surgical technique and postoperative care, and in later editions remained a standard reference up to the 1930s. He was the author of more than 400 papers on gynaecological and general abdominal surgery and his technical expertise drew surgeons from all over the world to his theatre in the Hospital Broca, in one of the poorer parts of Paris. He was equally successful in several professional fields apart from medicine. However, his name is now little known in the English-speaking world. This short biography aims to re-introduce Pozzi to readers of English.

    In the last 25 years, the continuous evolution in the design of prostheses for individuals with transfemoral and transtibial amputations has been remarkable. Mirroring this development is the dependency and expectancy of the prosthesis technology by the athletes, coaches and other personnel involved in creating Paralympians of today and the future. Össur is recognised as a leader in designing innovative prosthetic products that have contributed worldwide to developing leading Paralympians. The opening section of this article presents an overview of the new Össur products for 2012. Discussion is also focussed on how Össur's high-function prosthetic products are integrated into an athlete's training regime. With involvement of the clinical team discussion is also expanded to recognise the important contribution coaching staff has on optimising performance of a Paralympian's training regime. The dialogue continues with a viewpoint on whether Oscar Pistorius, the face of Össur who wears Flex-Foot Cheetah blades, should participate in the Olympics and Paralympics. While the conclusion of this article may leave more questions than answers, the technology and products offered by Össur provide for a credible foundation and preparation for future challenges beyond the London 2012 Paralympic Games.

  8. Towards a better understanding of the interaction between bed roughness and flow hydraulics in small eroded channels

    Rills eroding cohesive materials are hydraulically different from rivers or large channels. Unlike rivers, rills are small, shallow flow stream with frequently a relatively steep slope gradient. Besides, rills evolve morphologically over much shorter timescales due to active bed erosion. This leads to a strong interaction between the channel flow and bed roughness. This interaction gives rise to a reconfiguration of the bed geometry generated by the important erosive action of the flow. This new shape is characterized by a typical alternance between concavities (pools) and more or less flat reaches (steps). The new rill geometry affects, in turn, the behaviour of the flow that is why we talk about interaction or feedback. In addition, the greatest energy dissipation occurs in the pools -mainly due to the action of hydraulic jumps- which, in turn, lead to an increase in the pool size. We hypothesize there is a regular spacing of step-pools units and that, both the frequency and the depth of the pools will be strongly conditioned by the discharge and the general rill slope. The determination of that periodicity (if any) would be an important contribution for concentrated flow erosion modelling of small channels. That is because the majority of erosion models are based on formulations which assume that a rill has a flat bed, only affected by micro-roughness. For instance, equations like Manning's - widely used in river and large channel hydraulics -, if a constant value of roughness is assumed, would be inappropriate in erosion rills since, as explained above, the roughness is not constant. The objectives of this work are then: (i) to investigate the geometry of erosion rills aiming at determining if there is a spatial arrangement of the macro roughness of their beds; and (ii) to establish (semi)-empirical models of prediction of this periodicity, mainly based on topographic parameters. Rills were generated in an agricultural field in a homogeneous hillslope (with no

    As Global Positioning Satellite (GPS) applications become more prevalent for land- and air-based vehicles, GPS applications for space vehicles will also increase. The Applied Technology Directorate of Kennedy Space Center (KSC) has developed a lightweight, low-cost GPS Metric Tracking Unit (GMTU), the first of two steps in developing a lightweight, low-cost Space-Based Tracking and Command Subsystem (STACS) designed to meet Range Safety's link margin and latency requirements for vehicle command and telemetry data. The goals of STACS are to improve Range Safety operations and expand tracking capabilities for space vehicles. STACS will track the vehicle, receive commands, and send telemetry data through the space-based asset, which will dramatically reduce dependence on ground-based assets. The other step was the Low-Cost Tracking and Data Relay Satellite System (TDRSS) Transceiver (LCT2), developed by the Wallops Flight Facility (WFF), which allows the vehicle to communicate with a geosynchronous relay satellite. Although the GMTU and LCT2 were independently implemented and tested, the design collaboration of KSC and WFF engineers allowed GMTU and LCT2 to be integrated into one enclosure, leading to the final STACS. In operation, GMTU needs only a radio frequency (RF) input from a GPS antenna and outputs position and velocity data to the vehicle through a serial or pulse code modulation (PCM) interface. GMTU includes one commercial GPS receiver board and a custom board, the Command and Telemetry Processor (CTP) developed by KSC. The CTP design is based on a field-programmable gate array (FPGA) with embedded processors to support GPS functions.

This is particularly valid for data that allow for comparison of pain outcomes from one hospital to another. Such data are critical for numerous reasons, including allowing patients and policy-makers to make data-driven decisions, and to guide hospitals in their efforts to improve pain care. The Hospital Quality Alliance was recently created by federal policy makers and private organizations in conjunction with the Centers for Medicare and Medicare Services to conduct patient surveys to evaluate their experience including pain control during their hospitalization.Methods: In March 2008, the results of the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS survey was released for review for health care providers and researchers. This survey includes a battery of questions for patients upon discharge from the hospital including pain-related questions and patient satisfaction that provide valuable data regarding pain care nationwide. This study will review the results from the pain questions from this available data set and evaluate the performance of these hospitals in pain care in relationship to patient satisfaction.

A recent article in FORBES MAGAZINE found that SDG&E had the third highest price per kilowatt of any utility in the country--5.9{cents} per kilowatt hour for commercial customers. That was in March, 1980. Energy cost adjustment clause increases resulted in an average commercial price per kilowatt hour of 7.2{cents} in May. In July it is expected to climb to 9.2{cents}. SDG&E's rate territory continues to expand at the rate of 5% annually and it is located just over 100 miles from a major source of geothermal heat in the Imperial Valley. But today, SDG&E has no commercial geothermal heat or power purchase contracts with domestic producers. You may ask, ''Why not?'' With no incentive to spend its own money and with a high growth rate, what is SDG&E doing to obtain capacity for its existing and future customers? At the present time, most of SDG&E's capital expenditure for generation is going to the construction of San Onofre Units 2 and 3 , a nuclear project which has been under way for ten years and which is expected to start generating commercial power in 1982 and 1983.

    The problem of fundamental units is discussed in the context of achievements of both theoretical physics and modern metrology. On one hand, due to fascinating accuracy of atomic clocks, the traditional macroscopic standards of metrology (second, metre, kilogram) are giving way to standards based on fundamental units of nature: velocity of light $c$ and quantum of action $h$. On the other hand, the poor precision of gravitational constant $G$, which is widely believed to define the ``cube of theories'' and the units of the future ``theory of everything'', does not allow to use $G$ as a fundamental dimensional constant in metrology. The electromagnetic units in SI are actually based on concepts of prerelativistic classical electrodynamics such as ether, electric permitivity and magnetic permeability of vacuum. Concluding remarks are devoted to terminological confusion which accompanies the progress in basic physics and metrology.

    Distributed throughout hospital, research establishments in the United Kingdom and many other countries are Irradiation Units and Teletherapy machines used for either research purposes or treatment of patients for radiotherapy. These Irradiation Units and Teletherapy machines are loaded with radioactive sources of either Cobalt 60 or Caesium 137. The activity of these sources can range from 1 Terabecquerel up to 100 Terabecquerels or more. Where it is possible to load the radioactive sources without removal from the shielded container into a transport package which is suitable for transport decommissioning of a Teletherapy machine is not a major exercise. When the radioactive sources need to be unloaded from the Irradiation Unit or Teletherapy machine the potential exists for very high levels of radiation. The operation outlined in the paper involved the transfer from an Irradiation Unit to a transport package of two 3.25 Terabecquerel sources of Cobalt 60. The operation of the removal and transfer comes within the scope of the United Kingdom Ionising Radiation Regulations 1985 which were made following the Recommendations of the International Commission on Radiological Protection. This paper illustrates a safe method for this operation and how doses received can be kept within ALARA. (author)

  11. United Kingdom: Health System Review.

    Cylus, Jonathan; Richardson, Erica; Findley, Lisa; Longley, Marcus; O'Neill, Ciaran; Steel, David

    2015-01-01

    This analysis of the United Kingdom health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. It provides an overview of how the national health services operate in the four nations that make up the United Kingdom, as responsibility for organizing health financing and services was devolved from 1997. With devolution, the health systems in the United Kingdom have diverged in the details of how services are organized and paid for, but all have maintained national health services which provide universal access to a comprehensive package of services that are mostly free at the point of use. These health services are predominantly financed from general taxation and 83.5% of total health expenditure in the United Kingdom came from public sources in 2013. Life expectancy has increased steadily across the United Kingdom, but health inequalities have proved stubbornly resistant to improvement, and the gap between the most deprived and the most privileged continues to widen, rather than close. The United Kingdom faces challenges going forward, including how to cope with the needs of an ageing population, how to manage populations with poor health behaviours and associated chronic conditions, how to meet patient expectations of access to the latest available medicines and technologies, and how to adapt a system that has limited resources to expand its workforce and infrastructural capacity so it can rise to these challenges.

  16. Global Units modulo Circular Units : descent without Iwasawa's Main Conjecture

    CERN Document Server

    Belliard, Jean-Robert

    2009-01-01

    Iwasawa's classical asymptotical formula relates the orders of the $p$-parts $X_n$ of the ideal class groups along a $\\ZM_p$-extension $F_\\infty/F$ of a number field $F$, to Iwasawa structural invariants $\\la$ and $\\mu$ attached to the inverse limit $X_\\infty=\\limpro X_n$. It relies on "good" descent properties satisfied by $X_n$. If $F$ is abelian and $F_\\infty$ is cyclotomic it is known that the $p$-parts of the orders of the global units modulo circular units $U_n/C_n$ are asymptotically equivalent to the $p$-parts of the ideal class numbers. This suggests that these quotients $U_n/C_n$, so to speak unit class groups, satisfy also good descent properties. We show this directly, i.e. without using Iwasawa's Main Conjecture.

  17. POST CLOSURE INSPECTION AND MONITORING REPORT FOR CORRECTIVE ACTION UNIT 417: CENTRAL NEVADA TEST AREA - SURFACE, HOT CREEK VALLEY, NEVADA; FOR CALENDAR YEAR 2005

    2006-04-01

    Corrective Action Unit (CAU) 417, Central Nevada Test Area - Surface, is located in Hot Creek Valley in northern Nye County, Nevada, and consists of three areas commonly referred to as UC-1, UC-3, and UC-4. CAU 417 consists of 34 Corrective Action Sites (CASs) which were closed in 2000 (U. S. Department of Energy, National Nuclear Security Administration Nevada Operations Office, 2001). Three CASs at UC-1 were closed in place with administrative controls. At CAS 58-09-01, Central Mud Pit (CMP), a vegetated soil cover was constructed over the mud pit. At the remaining two sites CAS 58-09-02, Mud Pit and 58-09-05, Mud Pits (3), aboveground monuments and warning signs were installed to mark the CAS boundaries. Three CASs at UC-3 were closed in place with administrative controls. Aboveground monuments and warning signs were installed to mark the site boundaries at CAS 58-09-06, Mud Pits (5), CAS 58-25-01, Spill and CAS 58-10-01, Shaker Pad Area. Two CASs that consist of five sites at UC-4 were closed in place with administrative controls. At CAS 58-09-03, Mud Pits 9, an engineered soil cover was constructed over Mud Pit C. At the remaining three sites in CAS 58-09-03 and at CAS 58-10-05, Shaker Pad Area, aboveground monuments and warning signs were installed to mark the site boundaries. The remaining 26 CASs at CAU 417 were either clean-closed or closed by taking no further action. Quarterly post-closure inspections are performed at the CASs that were closed in place at UC-I, UC-3, and UC-4. During calendar year 2005, site inspections were performed on March 15, June 16, September 22, and December 7. The inspections conducted at the UC-1 CMP documented that the site was in good condition and continued to show integrity of the cover unit. No new cracks or fractures were observed until the December inspection. A crack on the west portion of the cover showed evidence of lateral expansion; however, it is not at an actionable level. The crack will be sealed by filling with

  18. Unsupervised segmentation with dynamical units.

    Science.gov (United States)

    Rao, A Ravishankar; Cecchi, Guillermo A; Peck, Charles C; Kozloski, James R

    2008-01-01

    In this paper, we present a novel network to separate mixtures of inputs that have been previously learned. A significant capability of the network is that it segments the components of each input object that most contribute to its classification. The network consists of amplitude-phase units that can synchronize their dynamics, so that separation is determined by the amplitude of units in an output layer, and segmentation by phase similarity between input and output layer units. Learning is unsupervised and based on a Hebbian update, and the architecture is very simple. Moreover, efficient segmentation can be achieved even when there is considerable superposition of the inputs. The network dynamics are derived from an objective function that rewards sparse coding in the generalized amplitude-phase variables. We argue that this objective function can provide a possible formal interpretation of the binding problem and that the implementation of the network architecture and dynamics is biologically plausible.

    Turbulence Heating ObserveR (THOR) is the first mission ever flown in space dedicated to plasma turbulence. On board THOR, data collected by the Turbulent Electron Analyser, the Ion Mass Spectrum analyser and the Cold Solar Wind ion analyser instruments will be processed by a common digital processor unit, the Particle Processing Unit (PPU). PPU architecture will be based on the state of the art space flight processors and will be fully redundant, in order to efficiently and safely handle the data from the numerous sensors of the instruments suite. The approach of a common processing unit for particle instruments is very important for the enabling of an efficient management for correlative plasma measurements, also facilitating interoperation with other instruments on the spacecraft. Moreover, it permits technical and programmatic synergies giving the possibility to optimize and save spacecraft resources.

  20. Ad valorem versus unit taxes

    DEFF Research Database (Denmark)

    Schröder, Philipp J.H.; Sørensen, Allan

    2010-01-01

    Real-world industries are composed from heterogeneous firms and substantial intra-industry reallocations take place, i.e. high productivity firms squeeze out low productivity firms. Previous tax-tool comparisons have not included these central forces of industry structure. This paper examines...... a general equilibrium monopolistic competition model with heterogeneous firms and intra-industry reallocations. We show that the welfare superiority of ad valorem over unit taxes under imperfect competition is not only preserved but amplified. The additional difference between the tools arises because unit...... taxes distort relative prices, which in turn reduces average industry productivity through reallocations (the survival and increased market share of lower productivity firms). Importantly, numerical solutions of the model reveal that the relative welfare loss from using the unit tax increases...

  1. Unit for cleaning drilling muds

    Energy Technology Data Exchange (ETDEWEB)

    Dorosh, M.M.; Dera, Ya.I.; Fesenko, M.M.; Makedonov, N.I.; Surkov, V.T.

    1983-01-01

    A design is proposed for a unit for cleaning drilling muds which includes a settling tank with input sleeve and a sleeve of the purified mud and hydrocyclones. In order to improve the effectiveness of the degree of purification, the unit is equipped with an ejector and sludge filter arranged under the settling tank in the form of a grid installed in the upper part of the settling tank and connected to the sleeve of purified mud, while the inlet sleeve is arranged tangentially. The proposed unit can operate during drilling with the use of muds on water and carbon bases. As a result of its use, the degree of purification of the drilling mud reaches 30-35%; there is an increase in mechanical drilling rate, the service life of the sand-separator and the silt separators and decrease in wear of the pump equipment.

    A total PACS will be inevitable for radiology practice within several years. To achieve a total PACS for radiology, a satisfactory digital radiographic unit is required, because approximately 65% of digital data for PACS comes from digital radiographs. There are several possibilities for producing digital radiographs, and 3 - 4 companies have been marketing digital radiographic devices. Some data regarding the digital radiographic units on the market are compared. It will aid in assessing the current status and availability of this aspect of development, as well as providing a summary of further development of digital radiographic technology.

Barkhudarov suggests six levels of UT, each level could serve as unit of different levels of translation. Many Chinese translators also expressed their opinions on this issue, but there is no settled answer yet. This paper tends to make a distinction between different texts:ordinary and special. Ordinary ones can adopt the UT of paragraph, while special ones should adopt special UTs according to their own characteristics.

    Full Text Available The article deals with semantic relations in phraseology in modern English. In particular, the authors attempt to analyze different perspectives on the problem of correlation of concepts such as phraseological variance and synonyms existing in Russian linguistics. In addition, the article reviews and analyzes the nature and mechanism of phraseological variance. Particular attention is paid to the criteria of a particular phraseological unit to variants or synonyms. It substantiates the idea that the most suitable for the modern English language seems the point of view that considers the variance of phraseological unit as a fixed rate of transformation of the language of this unit does not violate its semantic identity. The main content of the study is an analysis of the main types of options phraseological units of modern English language: the structural and grammatical (morphological, syntactic, lexical, lexical and stylistic and of quantitative. The article also examines the characteristics of phraseological synonyms that unlike phraseological variants are built on different images, different logical-conceptual and shades of meaning, scope and use of stylistic coloring.

    2007-01-01

    Using data from the nationally representative National Health and Social Life Survey, this study queried the correlates of masturbation in the United States in 1992. Among those aged 18-60, 38% (CI, 35-41) of women and 61% (CI, 57-65) of men reported any masturbation over the preceding year. The system of factors underlying masturbation was similar for both genders, consistent with a convergence in gender patterns of sexual expression in the United States. Among both women and men, masturbation responded to a stable sexualized personality pattern, catalyzed by early-life factors and manifested in current sexual traits. Strikingly, the masturbation-partnered sex linkage, often conceptualized either as compensating for unsatisfying sex or complementing a satisfactory sex life, appeared to be bimodal for both genders. For some, masturbation complemented an active and pleasurable sex life, while among others, it compensated for a lack of partnered sex or satisfaction in sex.

  7. Drought in Southwestern United States

    Science.gov (United States)

    2007-01-01

    The southwestern United States pined for water in late March and early April 2007. This image is based on data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite from March 22 through April 6, 2007, and it shows the Normalized Difference Vegetation Index, or NDVI, for the period. In this NDVI color scale, green indicates areas of healthier-than-usual vegetation, and only small patches of green appear in this image, near the California-Nevada border and in Utah. Larger areas of below-normal vegetation are more common, especially throughout California. Pale yellow indicates areas with generally average vegetation. Gray areas appear where no data were available, likely due to persistent clouds or snow cover. According to the April 10, 2007, update from the U.S. Drought Monitor, most of the southwestern United Sates, including Utah, Nevada, California, and Arizona, experienced moderate to extreme drought. The hardest hit areas were southeastern California and southwestern Arizona. Writing for the Drought Monitor, David Miskus of the Joint Agricultural Weather Facility reported that March 2007 had been unusually dry for the southwestern United States. While California's and Utah's reservoir storage was only slightly below normal, reservoir storage was well below normal for New Mexico and Arizona. In early April, an international research team published an online paper in Science noting that droughts could become more common for the southwestern United States and northern Mexico, as these areas were already showing signs of drying. Relying on the same computer models used in the Intergovernmental Panel on Climate Change (IPCC) report released in early 2007, the researchers who published in Science concluded that global warming could make droughts more common, not just in the American Southwest, but also in semiarid regions of southern Europe, Mediterranean northern Africa, and the Middle East.

  13. Strategic renewal for business units.

    Science.gov (United States)

    Whitney, J O

    1996-01-01

    Over the past decade, business units have increasingly taken the role of strategy formulation away from corporate headquarters. The change makes sense: business units are closer to customers, competitors, and costs. Nevertheless, business units can fail, just as headquarters once did, by losing their focus on the organization's priorities and capabilities. John Whitney--turnaround expert and professor of management at Columbia University--offers a method for refocusing companies that he calls the strategic-renewal process. The principles behind the process are straightforward, but its execution demands extensive data, rigorous analysis, and the judgment of key decision makers. However, when applied with diligence, it can produce a strategy that yields both growth and profit. To carry out the process, managers must analyze, one by one or in logical groupings, the company's customers, the products it sells, and the services it offers in light of three criteria: strategic importance, significance, and profitability. Does a given customer, product, or service mesh with the organization's goals? Is it significant in terms of current and future revenues? And is it truly profitable when all costs are care fully considered? Customers, products, and services that do not measure up, says the author, must be weeded out relentlessly. Although the process is a painstaking one, the article offers clear thinking on why-and how-to go about it. A series of exhibits takes managers through the questions they need to raise, and two matrices offer Whitney's concentrated wisdom on when to cultivate--and when to prune.

  14. Low cost balancing unit design

    Golembiovsky, Matej; Dedek, Jan; Slanina, Zdenek

    2017-06-01

    This article deals with the design of a low-cost balancing system which consist of battery balancing units, accumulator pack units and coordinator unit with interface for higher level of battery management system. This solution allows decentralized mode of operation and the aim of this work is implementation of controlling and diagnostic mechanism into an electric scooter project realized at Technical university of Ostrava. In todays world which now fully enjoys the prime of electromobility, off-grid battery systems and other, it is important to seek the optimal balance between functionality and the economy side of BMS that being electronics which deals with secondary cells of batery packs. There were numerous sophisticated, but not too practical BMS models in the past, such as centralized system or standalone balance modules of individual cells. This article aims at development of standalone balance modules which are able to communicate with the coordinator, adjust their parameters and ensure their cells safety in case of a communication failure. With the current worldwide cutting cost trend in mind, the emphasis was put on the lowest price possible for individual component. The article is divided into two major categories, the first one being desing of power electronics with emphasis on quality, safety (cooling) and also cost. The second part describes development of a communication interface with reliability and cost in mind. The article contains numerous graphs from practical measurements. The outcome of the work and its possible future is defined in the conclusion.

  15. Graphemes are perceptual reading units.

    Science.gov (United States)

    Rey, A; Ziegler, J C; Jacobs, A M

    2000-04-14

    Graphemes are commonly defined as the written representation of phonemes. For example, the word 'BREAD' is composed of the four phonemes /b/, /r/, /e/ and /d/, and consequently, of the four graphemes 'B', 'R', 'EA', and 'D'. Graphemes can thus be considered the minimal 'functional bridges' in the mapping between orthography and phonology. In the present study, we investigated the hypothesis that graphemes are processed as perceptual units by the reading system. If the reading system processes graphemes as units, then detecting a letter in a word should be harder when this letter is embedded in a multi-letter grapheme than when it corresponds to a single-letter grapheme. In Experiment 1A, done in English, participants were slower to detect a target letter in a word when the target letter was embedded in multi-letter grapheme (i.e. 'A' in 'BEACH') than when it corresponded to a single-letter grapheme (i.e. 'A' in 'PLACE'). In Experiment 1B, this effect was replicated in French. In Experiment 2, done in English, this grapheme effect remained when phonemic similarity between the target letter alone and the target letter inside the word was controlled. Together, the results are consistent with the assumption that graphemes are processed as perceptual reading units in alphabetic writing systems such as English or French.

    2014-12-21

    This binary plant is the first air cooled, high-output refrigeration based waste heat recovery cycle in the industry. Its working fluid is environmentally friendly and as such, the permits that would be required with a hydrocarbon based cycle are not necessary. The unit is largely modularized, meaning that the unit’s individual skids were assembled in another location and were shipped via truck to the plant site. The Air Cooled Condensers (ACC), equipment piping, and Balance of Plant (BOP) piping were constructed at site. This project further demonstrates the technical feasibility of using low temperature brine for geothermal power utilization. The development of the unit led to the realization of low temperature, high output, and environmentally friendly heat recovery systems through domestic research and engineering. The project generates additional renewable energy, resulting in cleaner air and reduced carbon dioxide emissions. Royalty and tax payments to governmental agencies will increase, resulting in reduced financial pressure on local entities. The major components of the unit were sourced from American companies, resulting in increased economic activity throughout the country.

  17. The First Drinking Simulator Unit

    Directory of Open Access Journals (Sweden)

    Saied Mostafa Moazzami

    2014-03-01

    Full Text Available Introduction: Current Thermal cycling units fail to simulate the drinking behaviors, and oral balancing temperature. They cannot also simulate other oral conditions such as drink coloring, and chemicals like tea, coffee, carbonated and noncarbonated, citrus juices as well as alcoholic and nonalcoholic drinks and also saliva and milk itself. The main objective of this study is to introduce the designing and manufacturing the first Drinking Simulator Unit (DSU that reproduces the thermal, color and chemicalcycling as well as the drinking behavior and oral temperature in lab conditions uniquely. Methods: The invented system generally has two parts: the hardware and the software parts. The hardware consists of the mechanical and electronic parts. The software part is responsible for controlling the heating and cooling systems, electric valves, the pumps, and automatic filling systems of tanks as well as the sensors of the machine. Results: DSU is the first unit can reproduce the thermal, color and chemical cycling as well as the drinking behavior and oral temperature in lab conditions. Different kinds of colored and acidic drinks and also other chemical materials such as bleaching substances as well as detergents and antiseptics used for dentistry, industrial and medical purposes can be tested by DSU. DSU has also to be considered as an appliance performing in-vitro researches on dental structures. Conclusion: The invented system can greatly improve and validate the results of such researches.

    Unit 1 of the Loviisa nuclear powerplant was annealed in connection with the refuelling outage in the summer of 1996. This type of heat treatment restored the toughness properties of the pressure vessel weld, which had been embrittled be neutron radiation, so that it is almost equivalent to a new weld. The treatment itself was an ordinary metallurgical procedure that took only a few days. But the material studies that preceded it began over fifteen years ago and have put IVO at the forefront of world-wide expertise in the area of radiation embrittlement

  1. Asymptotic Rayleigh instantaneous unit hydrograph

    Science.gov (United States)

    Troutman, B.M.; Karlinger, M.R.

    1988-01-01

    The instantaneous unit hydrograph for a channel network under general linear routing and conditioned on the network magnitude, N, tends asymptotically, as N grows large, to a Rayleigh probability density function. This behavior is identical to that of the width function of the network, and is proven under the assumption that the network link configuration is topologically random and the link hydraulic and geometric properties are independent and identically distributed random variables. The asymptotic distribution depends only on a scale factor, {Mathematical expression}, where ?? is a mean link wave travel time. ?? 1988 Springer-Verlag.

    The Enhanced Master Controller Unit Tester (EMUT) software is a tool for development and testing of software for a master controller (MC) flight computer. The primary function of the EMUT software is to simulate interfaces between the MC computer and external analog and digital circuitry (including other computers) in a rack of equipment to be used in scientific experiments. The simulations span the range of nominal, off-nominal, and erroneous operational conditions, enabling the testing of MC software before all the equipment becomes available.

    2007-06-26

    A compact monolithic capacitive discharge unit (CDU) is disclosed in which a thyristor switch and a flyback charging circuit are both sandwiched about a ceramic energy storage capacitor. The result is a compact rugged assembly which provides a low-inductance current discharge path. The flyback charging circuit preferably includes a low-temperature co-fired ceramic transformer. The CDU can further include one or more ceramic substrates for enclosing the thyristor switch and for holding various passive components used in the flyback charging circuit. A load such as a detonator can also be attached directly to the CDU.

    Full Text Available Equivalent Culture-Anchored Units Translation? The Phraseological Units Issue This article examines a question that has been of long-standing interest to linguists working in the fields of cross-linguistic phraseology and the translation of idiosyncratic language units, such as phraseological units (PUs. The challenge of translating PUs, which are understood as "patterns sanctioned by a given culture", involves the translation of culturemes. Therefore, a good translator must be able to assess the importance of the elements containing cultural references in the source language while "moving" them to the target language. When translating PUs, it is desirable that interlingual (cross-linguistic equivalence be achieved. The fact that translations of a PU can be very different (the translator can paraphrase the text, creatively change it, or simply eliminate the PU implies that the translational equivalence of PUs must be functional. While a cross-linguistic comparison (and the achievement of translational equivalence of PUs can be made by omitting the form parameter, it is desirable to preserve the extension and semantic structure, the connotative-pragmatic component, and the phrase combinatorics.   Ekwiwalencja jedostek "kulturowo zakotwiczonych"?

  8. The associated regulators and signal pathway in rILl-16/CD4 mediated growth regulation in Jurkat cells

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    IL-16 is a ligand and chemotactic factor for CD4+ T cells. IL-16 inhibits the CD3 mediated lymphocyteactivation and proliferation. The effects of IL-16 on the target cells are dependent on the cell type, thepresence of co-activators etc. To understand the regulation function and mechanism of IL-16 on targetcells, we used a 130 a.a. recombinant IL-16 to study its effects on the growth of Jurkat T leukemia cellsin vitro. We found that the rIL-16 stimulated the proliferation of Jurkat cells at low dose (10-9M), butinhibited the growth of the cells at higher concentration (10-5M). Results showed that 10-5 M of rIL-16treatment induced an enhanced apoptosis in Jurkat cells. The treatment blocked the expression of FasL, butup-regulated the c-myc and Bid expression in the cells. Pre-treatment of PKC inhibitor or MEK1 inhibitormarkedly increased or decreased the rIL-16 induced growth-inhibiting effects on Jurkat cells, respectively.The results suggested that the rIL-16 might be a regulator for the growth or apoptosis of Jurkat cells ata dose-dependent manner. The growth-inhibiting effects of rIL-16 might be Fas/FasL independent, but,associated with the activation of PKC, up-regulated expression of c-Myc and Bid, and the participation ofthe ERK signal pathway in Jurkat cells.

  9. Repeat rainfall simulation experiments for assessing the evolution of overland flow generation and inter-rill erosion following wildfire

    Science.gov (United States)

    Keizer, Jan Jacob; Malvar, Maruxa; Prats, Sergio; Nunes, João. Pedro

    2010-05-01

    The EROSFIRE project selected field rainfall simulation experiments (RSE's) as a time-and cost-effective approach to gather runoff and soil loss data under the rapidly changing conditions typical for commercial eucalypt plantations in Portugal following wildfires. These RSE data were first and foremost envisaged for initial parameterization and calibration of a physically-based model like MEFIDIS. Subsequent model assessment at larger spatial scales would then be based on slope-scale erosion plot data collected at a small number of selected sites. The present work, however, will in principle be confined to an analysis of the measurement results of the RSE's in two recently burnt eucalypt plantations. Repeat RSE's were carried out in two adjacent but contrasting eucalypt stands on steep hillslopes in north-central Portugal. This involved six occasions ranging from 3 to 24 months after a moderate severity fire in July 2005. A paired-plot experimental design was employed that comprised two pairs of RSE's at each site and occasion. From a grand total of 46 RSE's: (i) 24 and 22 RSE's involved application rates of 45-50 and 80-85 mm h-1, respectively; (ii) 22 took place in a stand that had been ploughed in downslope direction several years before the wildfire and 24 in an unploughed stand. The results showed a clear tendency for extreme-intensity RSE's to produce higher runoff amounts and greater soil and organic matter losses than the simultaneous high-intensity RSE's on the neighbouring plots. Nonetheless, there were marked exceptions, both in space (for one of the plot pairs) and time (under intermediate soil water repellency conditions). Also, overland flow generation and erosion varied significantly along the various field campaigns. This temporal pattern noticeably differed from a straightforward decline with time-after-fire, rather suggesting a seasonal component that reflected broad variations in topsoil water repellency. The ploughed site produced less runoff and erosion than the unploughed site, contrary to what would be expected if the downslope ploughing had occurred after the wildfire instead of several years before it. Finally, sediment losses at both study sites were noticeably lower than those reported by the other studies involving repeat RSE's, i.e. in Australia and western Spain. This possibly reflects a history of intensive land use in the study region, including in more recent times after the widespread introduction of eucalypt plantations.

  15. Asynchronous Capacity per Unit Cost

    CERN Document Server

    Chandar, Venkat; Tse, David

    2010-01-01

    The capacity per unit cost, or equivalently minimum cost to transmit one bit, is a well-studied quantity. It has been studied under the assumption of full synchrony between the transmitter and the receiver. In many applications, such as sensor networks, transmissions are very bursty, with small amounts of bits arriving infrequently at random times. In such scenarios, the cost of acquiring synchronization is significant and one is interested in the fundamental limits on communication without assuming a priori synchronization. In this paper, we show that the minimum cost to transmit B bits of information asynchronously is (B + \\bar{H})k_sync, where k_sync is the synchronous minimum cost per bit and \\bar{H} is a measure of timing uncertainty equal to the entropy for most reasonable arrival time distributions.

  16. Units of measure in clinical information systems.

    Science.gov (United States)

    Schadow, G; McDonald, C J; Suico, J G; Föhring, U; Tolxdorff, T

    1999-01-01

    The authors surveyed existing standard codes for units of measures, such as ISO 2955, ANSI X3.50, and Health Level 7's ISO+. Because these standards specify only the character representation of units, the authors developed a semantic model for units based on dimensional analysis. Through this model, conversion between units and calculations with dimensioned quantities become as simple as calculating with numbers. All atomic symbols for prefixes and units are defined in one small table. Huge permutated conversion tables are not required. This method is also simple enough to be widely implementable in today's information systems. To promote the application of the method the authors provide an open-source implementation of this method in JAVA. All existing code standards for units, however, are incomplete for practical use and require substantial changes to correct their many ambiguities. The authors therefore developed a code for units that is much more complete and free from ambiguities.

  19. Malaria Surveillance - United States, 2014.

    Science.gov (United States)

    Mace, Kimberly E; Arguin, Paul M

    2017-05-26

    Malaria in humans is caused by intraerythrocytic protozoa of the genus Plasmodium. These parasites are transmitted by the bite of an infective female Anopheles mosquito. The majority of malaria infections in the United States occur among persons who have traveled to regions with ongoing malaria transmission. However, malaria is occasionally acquired by persons who have not traveled out of the country through exposure to infected blood products, congenital transmission, laboratory exposure, or local mosquitoborne transmission. Malaria surveillance in the United States is conducted to identify episodes of local transmission and to guide prevention recommendations for travelers. This report summarizes cases in persons with onset of illness in 2014 and trends during previous years. Malaria cases diagnosed by blood film, polymerase chain reaction, or rapid diagnostic tests are reported to local and state health departments by health care providers or laboratory staff. Case investigations are conducted by local and state health departments, and reports are transmitted to CDC through the National Malaria Surveillance System, National Notifiable Diseases Surveillance System, or direct CDC consultations. CDC conducts antimalarial drug resistance marker testing on blood samples submitted by health care providers or local or state health departments. Data from these reporting systems serve as the basis for this report. CDC received reports of 1,724 confirmed malaria cases, including one congenital case and two cryptic cases, with onset of symptoms in 2014 among persons in the United States. The number of confirmed cases in 2014 is consistent with the number of confirmed cases reported in 2013 (n = 1,741; this number has been updated from a previous publication to account for delayed reporting for persons with symptom onset occurring in late 2013). Plasmodium falciparum, P. vivax, P. ovale, and P. malariae were identified in 66.1%, 13.3%, 5.2%, and 2.7% of cases, respectively

  20. Generating units performances: power system requirements

    Energy Technology Data Exchange (ETDEWEB)

    Fourment, C.; Girard, N.; Lefebvre, H.

    1994-08-01

    The part of generating units within the power system is more than providing power and energy. Their performance are not only measured by their energy efficiency and availability. Namely, there is a strong interaction between the generating units and the power system. The units are essential components of the system: for a given load profile the frequency variation follows directly from the behaviour of the units and their ability to adapt their power output. In the same way, the voltage at the units terminals are the key points to which the voltage profile at each node of the network is linked through the active and especially the reactive power flows. Therefore, the customer will experience the frequency and voltage variations induced by the units behaviour. Moreover, in case of adverse conditions, if the units do not operate as well as expected or trip, a portion of the system, may be the whole system, may collapse. The limitation of the performance of a unit has two kinds of consequences. Firstly, it may result in an increased amount of not supplied energy or loss of load probability: for example if the primary reserve is not sufficient, a generator tripping may lead to an abnormal frequency deviation, and load may have to be shed to restore the balance. Secondly, the limitation of a unit performance results in an economic over-cost for the system: for instance, if not enough `cheap` units are able to load-following, other units with higher operating costs have to be started up. We would like to stress the interest for the operators and design teams of the units on the one hand, and the operators and design teams of the system on the other hand, of dialog and information exchange, in operation but also at the conception stage, in order to find a satisfactory compromise between the system requirements and the consequences for the generating units.

It describes the various legislative bodies involved in regulating this activity and the inspectorate concerned. The licensing regime is described in some detail highlighting the UK arrangements whereby a license is granted for the site upon which nuclear facilities are planned or exist. The license remains in place throughout the life of the plant on the site: from initial planning through to the end of decommissioning. A site (of part of) is not de-licensed until it can be stated that there has ceased to be any danger from ionising radiations from anything on the site (or appropriate part of the site). The final part of the paper considers the changes arising from the commercialization of the nuclear power industry in UK and the restatement of the Nuclear Installation Inspectorate`s policy on decommissioning which has arisen as a result of a review made in response to these changes.

    Sahlmann, Johannes; Abuter, Roberto; Accardo, Matteo; Mottini, Sergio; Delplancke, Francoise

    2009-01-01

    The Fringe Sensor Unit (FSU) is the central element of the Phase Referenced Imaging and Micro-arcsecond Astrometry (PRIMA) dual-feed facility and provides fringe sensing for all observation modes, comprising off-axis fringe tracking, phase referenced imaging, and high-accuracy narrow-angle astrometry. It is installed at the Very Large Telescope Interferometer (VLTI) and successfully servoed the fringe tracking loop during the initial commissioning phase. Unique among interferometric beam combiners, the FSU uses spatial phase modulation in bulk optics to retrieve real-time estimates of fringe phase after spatial filtering. A R=20 spectrometer across the K-band makes the retrieval of the group delay signal possible. The FSU was integrated and aligned at the VLTI in summer 2008. It yields phase and group delay measurements at sampling rates up to 2 kHz, which are used to drive the fringe tracking control loop. During the first commissioning runs, the FSU was used to track the fringes of stars with K-band magnitu...

  3. Neurovascular Unit in Chronic Pain

    2013-01-01

    Full Text Available Chronic pain is a debilitating condition with major socioeconomic impact, whose neurobiological basis is still not clear. An involvement of the neurovascular unit (NVU has been recently proposed. In particular, the blood-brain barrier (BBB and blood-spinal cord barrier (BSCB, two NVU key players, may be affected during the development of chronic pain; in particular, transient permeabilization of the barrier is suggested by several inflammatory- and nerve-injury-based pain models, and we argue that the clarification of molecular BBB/BSCB permeabilization events will shed new light in understanding chronic pain mechanisms. Possible biases in experiments supporting this theory and its translational potentials are discussed. Moving beyond an exclusive focus on the role of the endothelium, we propose that our understanding of the mechanisms subserving chronic pain will benefit from the extension of research efforts to the NVU as a whole. In this view, the available evidence on the interaction between analgesic drugs and the NVU is here reviewed. Chronic pain comorbidities, such as neuroinflammatory and neurodegenerative diseases, are also discussed in view of NVU changes, together with innovative pharmacological solutions targeting NVU components in chronic pain treatment.

    In the United States the Accreditation Council of Graduate Medical Education determines the curriculum required for fellows in forensic psychiatry to become board certified as a subspecialist. Areas that must be covered during the one year fellowship include criminal issues, such as insanity; civil issues, such as tort law and Workers' Compensation; legal regulation of psychiatry, such as confidentiality and involuntary hospitalization; and correctional psychiatry issues, such as dual agency and prisoner's rights. Fellows are also expected to have knowledge about juvenile courts, the structure of the legal system, and child custody issues. In addition, fellows are required to analyze complex cases and write forensic reports which are well reasoned. Teaching methods include lectures, storytelling, use of video vignettes, and mock trials. Additional teaching methodologies include group supervision of fellows in their report writing and direct observation of giving testimony. During the year we see fellows evolve and shift their orientation from being an advocate for patients to perceiving their role as serving justice.

  5. FRIDA integral field unit manufacturing

    Cuevas, Salvador; Eikenberry, Stephen S.; Sánchez, Beatriz

    2014-07-01

    FRIDA (inFRared Imager and Dissector for the Adaptive optics system of the Gran Telescopio Canarias) has been designed as a cryogenic and diffraction limited instrument that will offer broad and narrow band imaging and integral field spectroscopy (IFS). Both, the imaging mode and IFS observing modes will use the same Teledyne 2Kx2K detector. This instrument will be installed at Nasmyth B station, behind the GTC Adaptive Optics system (GTCAO). FRIDA will provide the IFS mode using a 30 slices Integral Field Unit (IFU). This IFU design is based on the University of Florida FISICA where the mirror block arrays are diamond turned on monolithic metal blocks. The FRIDA IFU is of the slicer type; conformed mainly by 3 mirror blocks with 30 spherical mirrors each. It also has a Schwarzschild relay based on two off axis spherical mirrors and an afocal system of two parabolic off axis mirrors. Including two insertion mirrors the IFU holds 96 metal mirrors. All the mirrors have been manufactured by diamond turning techniques on monolithic blocks of aluminum 6061-T6 coated by a Nickel alloy. Except for the Schwarzschild relay and the insertion mirrors, 92 mirrors were manufactured by Corning in Keene NH, USA. The different blocks and mirrors are mounted on an opto-mechanical support that ensures the image quality and integrity of the complete IFU. In this work advances on the manufacturing of the FRIDA IFU components are described. Furthermore, the mirror blocks individual verification tests and are also described.

    2006-03-01

    Patients in the acute care units (ACU) are usually critically ill, making them more susceptible to the unfavorable atmosphere in the hospital. One of these unfavorable factors is sleep disruption and deprivation. Many factors may affect sleep in the ACU, including therapeutic interventions, diagnostic procedures, medications, the underlying disease process, and noise generated in the ACU environment. Many detrimental physiological effects can occur secondary to noise and sleep deprivation, including cardiovascular stimulation, increased gastric secretion, pituitary and adrenal stimulation, suppression of the immune system and wound healing, and possible contribution to delirium. Over the past few years, many studies have endeavored to objectively assess sleep in the ACUs, as well as the effect of mechanical ventilation and circadian rhythm changes critically ill patients. At this time, therefore, it is important to review published data regarding sleep in ACUs, in order to improve the knowledge and recognition of this problem by health care professionals. We have therefore reviewed the methods used to assess sleep in ACUs, factors that may affect sleep in the ACU environment, and the clinical implications of sleep disruption in the ACU.

    Full Text Available The migration issue is a debatable one not only from a theoretical point of view but from the policy options as well. The progress in explaining various aspects of international migration such as migration strategy, from individual to family strategy, the way of entering the new country, from “chain” to “network migration” and trans-nationality etc. has not always been followed by the most appropriate policy options. Because of political interest, policy makers are more sensitive to the public opinion perception on migration than to the scientific opinions concerning the balance between advantages and disadvantages of migrants’ presence.

  13. Portable Unit for Metabolic Analysis

    Dietrich, Daniel L.; Pitch, Nancy D.; Lewis, Mark E.; Juergens, Jeffrey R.; Lichter, Michael J.; Stuk, Peter M.; Diedrick, Dale M.; Valentine, Russell W.; Pettegrew, Richard D.

    The Portable Unit for Metabolic Analysis (PUMA) is an instrument that measures several quantities indicative of human metabolic function. Specifically, this instrument makes time-resolved measurements of temperature, pressure, flow, and the partial pressures of oxygen and carbon dioxide in breath during both inhalation and exhalation. Portable instruments for measuring these quantities have been commercially available, but the response times of those instruments are too long to enable temporal resolution of phenomena on the time scales of human respiration cycles. In contrast, the response time of the PUMA is significantly shorter than characteristic times of human respiration phenomena, making it possible to analyze varying metabolic parameters, not only on sequential breath cycles but also at successive phases of inhalation and exhalation within the same breath cycle. In operation, the PUMA is positioned to sample breath near the subject s mouth. Commercial off-the-shelf sensors are used for three of the measurements: a miniature pressure transducer for pressure, a thermistor for temperature, and an ultrasonic sensor for flow. Sensors developed at Glenn Research Center are used for measuring the partial pressures of oxygen and carbon dioxide: The carbon dioxide sensor exploits the relatively strong absorption of infrared light by carbon dioxide. Light from an infrared source passes through the stream of inhaled or exhaled gas and is focused on an infrared- sensitive photodetector. The oxygen sensor exploits the effect of oxygen in quenching the fluorescence of ruthenium-doped organic molecules in a dye on the tip of an optical fiber. A blue laser diode is used to excite the fluorescence, and the optical fiber carries the fluorescent light to a photodiode, the temporal variation of the output of which bears a known relationship with the rate of quenching of fluorescence and, hence, with the partial pressure of oxygen. The outputs of the sensors are digitized

That's why two eminent physicists, Georges Charpak of France, and Richard Garwin, are proposing the DARI as a unit of radiation dose they hope will help the public evaluate the risks associated with low-level radiation exposure (1 page)

    Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 2013. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2013, data were received from 49 reporting areas. For trend analysis, abortion data were evaluated from 47 areas that reported data every year during 2004-2013. Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births). A total of 664,435 abortions were reported to CDC for 2013. Of these abortions, 98.2% were from the 47 reporting areas that provided data every year during 2004-2013. Among these 47 reporting areas, the abortion rate for 2013 was 12.5 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 200 abortions per 1,000 live births. From 2012 to 2013, the total number, rate, and ratio of reported abortions decreased 5%. From 2004 to 2013, the total number, rate, and ratio of reported abortions decreased 20%, 21%, and 17%, respectively. In 2013, all three measures reached their lowest level for the entire period of analysis (2004-2013). In 2013 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2013, women aged 20-24 and 25-29 years accounted for 32.7% and 25.9% of all abortions, respectively, and had abortion rates of 21.8 and 18.2 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 16.8%, 9.2%, and 3.6% of all abortions, respectively, and had abortion rates of 11.8, 7.0, and 2

    Cultural traits have long been used in anthropology as units of transmission that ostensibly reflect behavioural characteristics of the individuals or groups exhibiting the traits. After they are transmitted, cultural traits serve as units of replication in that they can be modified as part of an individual's cultural repertoire through processes such as recombination, loss or partial alteration within an individual's mind. Cultural traits are analogous to genes in that organisms replicate them, but they are also replicators in their own right. No one has ever seen a unit of transmission, either behavioural or genetic, although we can observe the effects of transmission. Fortunately, such units are manifest in artefacts, features and other components of the archaeological record, and they serve as proxies for studying the transmission (and modification) of cultural traits, provided there is analytical clarity over how to define and measure the units that underlie this inheritance process.

  19. The vacuum impedance and unit systems

    CERN Document Server

    Kitano, M

    2006-01-01

    In electromagnetism, the vacuum impedance $Z_0$ is a universal constant, which is as important as the velocity of light $c$ in vacuum. Unfortunately, however, its significance does not seem to be appreciated so well and sometimes the presence itself is ignored. It is partly because in the Gaussian system of units, which has widely been used for long time, $Z_0$ is a dimensionless constant and of unit magnitude. In this paper, we clarify that $Z_0$ is a fundamental parameter in electromagnetism and plays major roles in the following scenes: reorganizing the structure of the electromagnetic formula in reference to the relativity; renormalizing the quantities toward natural unit systems starting from the SI unit system; and defining the magnitudes of electromagnetic units.

  1. Assessment of Motor Units in Neuromuscular Disease.

    Science.gov (United States)

    Henderson, Robert D; McCombe, Pamela A

    2017-01-01

    The motor unit comprises the anterior horn cell, its axon, and the muscle fibers that it innervates. Although the true number of motor units is unknown, the number of motor units appears to vary greatly between different muscles and between different individuals. Assessment of the number and function of motor units is needed in diseases of the anterior horn cell and other motor nerve disorders. Amyotrophic lateral sclerosis is the most important disease of anterior horn cells. The need for an effective biomarker for assessing disease progression and for use in clinical trials in amyotrophic lateral sclerosis has stimulated the study of methods to measure the number of motor units. Since 1970 a number of different methods, including the incremental, F-wave, multipoint, and statistical methods, have been developed but none has achieved widespread applicability. Two methods (MUNIX and the multipoint incremental method) are in current use across multiple centres and are discussed in detail in this review, together with other recently published methods. Imaging with magnetic resonance and ultrasound is increasingly being applied to this area. Motor unit number estimates have also been applied to other neuromuscular diseases such as spinal muscular atrophy, compression neuropathies, and prior poliomyelitis. The need for an objective measure for the assessment of motor units remains tantalizingly close but unfulfilled in 2016.

    Clay, S A; Ramseyer, J C; Fishman, L S; Sedgwick, R P

    1977-04-01

    Eight infants with an acute reversible motor unit disorder are described, including two infants from whom Clostridum botulinum type A was isolated from stool specimens. The clinical spectrum includes constipation, cranial nerve deficits, pupillary involvement, and generalized hypotonic weakness. There were no deaths, and all infants have had complete clinical recovery. A characteristic electromyographic (EMG) pattern was present in part until clinical recovery. This distinctive pattern consisted of brief, small, abundant for power exerted motor unit potentials. This EMG pattern in the context of the clinical syndrome may well be diagnostic for acute infantile motor unit disorder.

    A flow chart depicting energy flow in the transportation sector of the United States economy in 2005 has been constructed from publicly available data and estimates of national energy use patterns. Approximately 31,000 trillion British Thermal Units (trBTUs) of energy were used throughout the United States in transportation activities. Vehicles used in these activities include automobiles, motorcycles, trucks, buses, airplanes, rail, and ships. The transportation sector is powered primarily by petroleum-derived fuels (gasoline, diesel and jet fuel). Biomass-derived fuels, electricity and natural gas-derived fuels are also used. The flow patterns represent a comprehensive systems view of energy used within the transportation sector.

    Full Text Available A firewall function is indispensable for mobile devices and it demands low-power operations. To realize this demand, the authors have developed a firewall unit with a reconfigurable device. The firewall unit needs a large amount of register for the timing adjustment of packets. Using the registers is the cause of power consumption. In this paper, to solve the problem of power consumption, the firewall unit has developed by using wave-pipelining technique and detailed delay time for the technique is analyzed.

  11. CRITICAL UNIT STREAM POWER FOR SEDIMENT TRANSPORT

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    Yang's (1996) sediment transport theory based on unit stream power is one of the most accurate theories, but in his equations the use of product of slope and critical velocity instead for critical unit stream power is not suitable. Dimensionless critical unit stream power required at incipient motion can be derived from the principle of conservation of power as a function of dimensionless particle diameter and relative roughness. Based on a lot of data sets, this new criterion was developed. By use of this new criteria, Yang's (1973) sand transport formula and his 1984 gravel transport formula could be improved when sediment concentration is less than about 100 ppm by weight.

  13. Does racism affect health? Evidence from the United States and the United Kingdom.

    Muennig, Peter; Murphy, Michael

    2011-02-01

    Blacks have worse overall health than whites in both the United States and the United Kingdom. However, the relative difference in health between the two groups within each cultural context differs between each context. In this article, we attempt to glean insights into these health disparities. We do so by first examining what is currently known about differences in morbidity and mortality for blacks and whites in the United States and the United Kingdom. We then turn to medical examination data by race and country of birth in an attempt to further untangle the complex interplay of socioeconomic status (SES), race, and racism as determinants of health in the United States and the United Kingdom. We find that (1) longer exposure of blacks to the recipient country is a risk for mortality in the United States but not in the United Kingdom; (2) adjustment for SES matters a good deal for mortality in the United States, but less so in the United Kingdom; (3) morbidity indicators do not paint a clear picture of black disadvantage relative to whites in either context; and (4) were one to consider medical examination data alone, differences between the two groups exist only in the United States. Taken together, we conclude that it is possible that the "less racist" United Kingdom provides a healthier environment for blacks than the United States. However, there remain many mysteries that escape simple explanation. Our findings raise more questions than they answer, and the health risks and health status of blacks in the United States are much more complex than previously thought.

    Many challenges exist in today's health care delivery system, and much focus and research are invested into ways to improve care with cost-effective measures. Specialty-specific dedicated care units are one solution for inpatient hospital care because they improve outcomes and decrease mortality. The neuroscience population encompasses a wide variety of diagnoses of spinal to cranial issues with a wide spectrum of needs varying from one patient to the next. Neuroscience care must be patient-specific during the course of frequent acuity changes, and one way to achieve this is through a neuroscience-focused unit. Few resources are available on how to implement this type of unit. Advanced practice nurses are committed to providing high-quality, safe, and cost-effective care and are instrumental in the success of instituting a unit dedicated to the care of neuroscience patients.

    2007-07-11

    This work examines the occurrence of native acetylated lignin in a large set of vascular plants, including both angiosperms and gymnosperms, by a modification of the so-called Derivatization Followed by Reductive Cleavage (DFRC) method. Acetylated lignin units were found in the milled wood lignins of all angiosperms selected for this study, including mono- and eudicotyledons, but were absent in the gymnosperms analyzed. In some plants (e.g., abaca, sisal, kenaf, or hornbeam), lignin acetylation occurred at a very high extent, exceeding 45% of the uncondensed (alkyl-aryl ether linked) syringyl lignin units. Acetylation was observed exclusively at the gamma-carbon of the lignin side chain and predominantly on syringyl units, although a predominance of acetylated guaiacyl over syringyl units was observed in some plants. In all cases, acetylation appears to occur at the monomer stage, and sinapyl and coniferyl acetates seem to behave as real lignin monomers participating in lignification.

    Kagawa, A.

    2013-12-01

    Over the last few decades, the United Nations (UN) has been approached by Security Council and Member States on international boundary issues. The United Nations regards the adequate delimitation and demarcation of international boundaries as a very important element for the maintenance of peace and security in fragile post-conflict situations, establishment of friendly relationships and cross-border cooperation between States. This paper will present the main principles and framework the United Nations applies to support the process of international boundary delimitation and demarcation activities. The United Nations is involved in international boundary issues following the principle of impartiality and neutrality and its role as mediator. Since international boundary issues are multi-faceted, a range of expertise is required and the United Nations Secretariat is in a good position to provide diverse expertise within the multiple departments. Expertise in different departments ranging from legal, political, technical, administrative and logistical are mobilised in different ways to provide support to Member States depending on their specific needs. This presentation aims to highlight some of the international boundary projects that the United Nations Cartographic Section has been involved in order to provide the technical support to different boundary requirements as each international boundary issue requires specific focus and attention whether it be in preparation, delimitation, demarcation or management. Increasingly, the United Nations is leveraging geospatial technology to facilitate boundary delimitation and demarcation process between Member States. Through the presentation of the various case studies ranging from Iraq - Kuwait, Israel - Lebanon (Blue Line), Eritrea - Ethiopia, Cyprus (Green Line), Cameroon - Nigeria, Sudan - South Sudan, it will illustrate how geospatial technology is increasingly used to carry out the support.

    Full Text Available Background: Nurses in intensive care units (ICUs are exposed regularly to huge demands interms of fulfilling the many roles that are placed upon them. Unit managers, in particular, are responsible for the efficient management of the units and have the responsibilities of planning, organising, leading and controlling the daily activities in order to facilitate the achievement of the unit objectives.Objectives: The objective of this study was to explore and present the challenges encountered by ICU managers in the management of large ICUs.Method: A qualitative, exploratory and descriptive study was conducted at five hospital ICUs in Gauteng province, South Africa. Data were collected through individual interviews from purposively-selected critical care unit managers, then analysed using the matic coding.Results: Five themes emerged from the data: challenges related to the layout and structure of the unit, human resources provision and staffing, provision of material resources, stressors in the unit and visitors in the ICU.Conclusion: Unit managers in large ICUs face multifaceted challenges which include the demand for efficient and sufficient specialised nurses; lack of or inadequate equipment that goes along with technology in ICU and supplies; and stressors in the ICU that limit the efficiency to plan, organise, lead and control the daily activities in the unit. The challenges identified call for multiple strategies to assist in the efficient management of large ICUs.

    This report represents the second of two providing a consumer-oriented comparison of commercially available auditory evoked potential units. The units compared here were those whose basic price was between $10,000-$30,000 ("midpriced"), and greater than $30,000 ("luxury"). The midpriced group included the Amplaid MK15, Bio-Logic Navigator and Traveler LT, Cadwell 5200A and Quantum 84, GSI-50, Nicolet CA-2000 and Compact Auditory, Nihon-Kohden Neuropak IV Mini, Madsen ERA2250, Siegen (Dantec) Neuroscope, and Tracor Nomad. The luxury units comprised the Bio-Logic Brain Atlas, Cadwell Spectrum 32 and Nicolet Pathfinder. Descriptive information and the names and addresses of users were solicited from the manufacturers for each of the above units. Questionnaires were sent to the users asking them for information on how their unit was used and to rate some of its features. The midpriced and luxury units offer more flexibility and options than less expensive (i.e., "economy") units. However, the basis for a given unit's price versus another's was not always apparent by a comparison of features or options. In general, users of the midpriced and luxury units rated the majority of their instruments' features highly. The lowest ratings were received for some aspect of the printer or print-out, and portability.

  8. Graviton as a Grand United Gauge Boson

    Science.gov (United States)

    Sharafiddinov, Rasulkhozha S.

    2015-04-01

    To any type of charge corresponds a kind of inertial mass. Such a mass-charge duality explains the availability in the neutrino of the naturally united rest mass and charge equal to all its mass and charge consisting of the electric, weak, strong and a range of other the innate components. From their point of view, we discuss a new theory of a grand unification. In this theory, the gravitational field is a naturally united field of the unified system of the most diverse combinations of the electric photons, magnetic monophotons, weak bosons and the strong gluons where the four pairs of forces of a different nature are united. Some consequences and laboratory confirmations of the discussed theory have been listed, in which graviton is predicted as a grand united gauge boson. Therefore, the gravitons constitute a natural light testifying in favor of gravitational force. They show that to each type of light corresponds a kind of force. Thereby, the suggested field theory that unites all gauge bosons in gravitons gives the possibility to directly look on the nature of gravitational matter elucidating the interratio of intragraviton forces and the problem of elementary particle fundamental symmetries.

  9. Ectopic folliculosebaceous units at the coronal sulcus.

    2014-12-01

    Tyson glands were described in the 17th century as modified sebaceous glands of the coronal sulcus of the penis. However, this description and other early texts supporting the existence of Tyson glands were not accompanied by illustrations. The existence of such glands has been passing through the literature without adequate graphical demonstration, which has contributed to controversial debates. Herein we present a case of a partial penectomy performed on a 65-year-old man with a squamous cell carcinoma of the penis. In this case we identified sebaceous glands as well as folliculosebaceous units in the coronal sulcus. We also comparatively examined 12 cases of partial penectomy to search for sebaceous glands or folliculosebaceous units in the coronal sulcus or the preputium. We found neither sebaceous glands nor folliculosebaceous units at the coronal sulcus or the mucosal aspect of the prepuce. We conclude that: (1) folliculosebaceous units are possible in the coronal sulcus, as the current case illustrates for the first time in literature and (2) the current case is an oddity, probably induced by the accompanying squamous cell carcinoma, and therefore it may represent an ectopic folliculosebaceous unit rather than an anatomic variation.

  10. Low resource ventilation unit; Ressourcebesparende ventilationsenhed

    Energy Technology Data Exchange (ETDEWEB)

    Drivsholm, C.

    2012-03-15

    In the project a resource-saving ventilation device was developed which is based on the use of a regenerator and a reversible air flow. The regenerator is placed in the building envelope, and the concept works in the way that the heat in the air during ventilation is stored in the regenerator and brought back into the building by a reversible air change. The heated air is blown from inside the building out through the regenerator. In this way the regenerator accumulates the heat in the air. Over a period of 30-120 seconds, the regenerator capacity is utilized. When the regenerator cannot be further heated, the air flow is reversed and there is now blown cold air through the regenerator. Thereby the heat from the regenerator is released to the cold fresh air. Thus, the fresh air brings heat back into the building, whereby the air is replaced with a limited heat loss. Ventilation with a regenerator is described as micro-ventilation. The developed micro-ventilation unit was tested by the Danish Technological Institute. The test results shows that the unit performs according to expectations: 1) The heat recovery is 85%; 2) The flow through the unit is 80m3 per hour in a 5 section unit; 3) The noise level is 30 db(A) in a representative room; 4) The energy consumption is <300 J/m3. The unit is introduced into the market, and the first plants have been sold. (LN)

  11. Curing efficiency of modern LED units.

    Rencz, Adam; Hickel, Reinhard; Ilie, Nicoleta

    2012-02-01

    Recent reports claim that modern light-emitting diode (LED) curing units improve curing efficiency by increasing the units' irradiance. In this context also, short polymerisation times up to 5 s are proposed. The aim of this study was to examine whether there are differences in the curing efficiency of modern LED curing units by assessing their effect on two different composite materials and by varying the irradiation time. A nano- and a micro-hybrid resin-based composite (RBC) were polymerised for 5, 10 and 20 s with three commercial and a Prototype LED unit (Elipar™ S10). Cylindrical specimens (6 mm in depth, 4 mm in diameter) were prepared in three increments, each 2-mm thick, and were consecutively cured. Degree of cure was measured for 20 min in real time at the bottom of the samples, starting with the photoinitiation. The micro-mechanical properties (modulus of elasticity, E and Vickers hardness, HV) were measured as a function of depth, in 100-μm steps, on the above described samples stored in distilled water for 24 h at 37°C. Data were analysed with multivariate ANOVA followed by Tukey's test, t test and partial eta-squared statistics. In descending order of the strength of their effect, the type of RBC, depth, polymerisation time and curing unit were significant factors affecting the micro-mechanical parameters (p surface, a minimum of 20 s of irradiation is necessary for an adequate polymerisation 2 mm beyond the surface.

  12. Simulation training for hyperacute stroke unit nurses.

    Science.gov (United States)

    Roots, Angela; Thomas, Libby; Jaye, Peter; Birns, Jonathan

    National clinical guidelines have emphasized the need to identify acute stroke as a clinical priority for early assessment and treatment of patients on hyperacute stroke units. Nurses working on hyperacute stroke units require stroke specialist training and development of competencies in dealing with neurological emergencies and working in multidisciplinary teams. Educational theory suggests that experiential learning with colleagues in real-life settings may provide transferable results to the workplace with improved performance. Simulation training has been shown to deliver situational training without compromising patient safety and has been shown to improve both technical and non-technical skills (McGaghie et al, 2010). This article describes the role that simulation training may play for nurses working on hyperacute stroke units explaining the modalities available and the educational potential. The article also outlines the development of a pilot course involving directly relevant clinical scenarios for hyperacute stroke unit patient care and assesses the benefits of simulation training for hyperacute stroke unit nurses, in terms of clinical performance and non-clinical abilities including leadership and communication.

  13. Is water in dental units microbiologically safe?

    Directory of Open Access Journals (Sweden)

    Michał Michałkiewicz

    2015-12-01

    Full Text Available Background: Water supplied to the dental units must be of sufficient quality. The article presents the results of the microbiological analysis of cold municipal water which flows into a patient’s disposable mouthwash cup, and demineralized water which flows through a waterline into the tool panel of a dental unit from the tank placed in the water group. Material and Methods: In order to assess the degree of purity (impurities of water used in dental units, 2 series of microbiological tests were carried out in 6 dental surgeries from April to June, 2013. The water samples for microbiological testing were collected into sterile microbiological bottles in accordance with the current methodology. The water for the tests was collected from a sterile cup-filling tap (municipal water and from an air/water syringe (demineralized water. The bacteria were cultured according to the Polish Standards – PN-EN ISO 6222, PN-EN ISO 9308-1, and PN-EN ISO 16266. Results: In the tested samples of water numerous psychrophilic bacteria (max 29 100 CFU/ml and mesophilic bacteria (max 24 700 CFU/ml, including single coliforms, were found. Conclusions: The results show that water delivered to a dental unit should be periodically tested bacteriologically and in terms of physical and chemical properties. Water systems of dental units should also be periodically disinfected to eliminate bacteria and biofilm. Med Pr 2015;66(6:763–770

  14. Stepwise redefinition of the SI base units

    CERN Document Server

    Issaev, L K; Khruschov, V V

    2012-01-01

    The four SI base units are proposed to be redefined in two stages: first, the kilogram, mole and ampere should be defined, and then the kelvin. To realize the redefinition of a base unit of the SI in terms of fundamental physical constant (FPC), a principle of coincidence of their physical dimensions is put forward. Direct applying this principle will lead to the changing of the sets of base and derived units in the new SI. If we want to preserve the continuity of the division between base and derived units in the new and the current SI, the principle is to be generalized with the time dimension factor be included. The status of the mole as the base unit of measurement is considered in the current and new SI. It is proposed to redefine the kilogram using a fixed value of the Avogadro constant and then to redefine the kelvin, after the measurement accuracy of the Boltzmann constant has been increased and agreed with the values of other constants of molecular physics.

    @@ The beam-type pumping unit is the most widely used ty pe of pumping unit because of its simple geometry and its reliability. However. when its stroke exceeds five meters, the structure of the unit becomes massive and its cost becomes quite high. In order to make full use of the advantages of the beam pumping unit and to enhance its stroke. a new type of pumping unit - the ECCENTRIC PUMPING UNIT - has been designed after two years of the research work.

    My unit on sound and waves is embedded within a long-term project in which my high school students construct a musical instrument out of common materials. The unit culminates with a performance assessment: students play the first four measures of "Somewhere Over the Rainbow"—chosen because of the octave interval of the first two notes—in the key of C, and write a short paper describing the theory underlying their instrument. My students have done this project for the past three years, and it continues to evolve. This year I added new instructional materials that I developed using a freeware program called Audacity. This software is very intuitive, and my students used it to develop their musical instruments. In this paper I will describe some of the inexpensive instructional materials in my sound unit, and how they fit with my learning goals.
