    Two- and three-dimensional finite element analysis programs for pile-soil interaction are compiled. Duncan-Chang's Model is used. The construction sequence of the pier is modeled. The pile-soil interface element is used. The influence of the combination type of piles on the deformation of bank slope and pile behaviour is analyzed. Different designs of a pile-supported pier are compared thoroughly. Calculation results show that the stresses and displacements of the pile are directly related to the distance from the bank slope and the direction of inclination. An inclined prop pile set in the rear platform would remarkably reduce the stresses of piles and the displacement of the pier.

    2016-01-01

    The equilibrium scour depth at uniform single bridge piers depends on a large number of variables, including the pier horizontal cross-section shape and its alignment angle towards the flow direction. The influence of these variables has been studied by only a few researchers, mostly, on the basis of tests that were far from approaching equilibrium. This experimental study aims at revisiting the influence of piers' shape and alignment on local scouring for length–width ratios smaller than or equal to 4, by increasing the experimental evidence. Fifty five long-duration laboratory tests were run under steady, clear-water flow, close to the threshold for initiation of sediment motion. Five pier shapes were considered:circular, rectangular square-nosed, rectangular round-nosed, oblong, and zero-spacing (packed) pile-groups;the tested skew-angles were 0°, 30°, 45°, 60°, and 90°. It was concluded that i) the shape factor can be taken as 1.0, for rectangular round-nosed and oblong cross-section piers, and as 1.2, for rectangular square-nosed and packed pile-group cross-section piers, ii) the shape factor does not vary significantly with the duration of tests, this way confirming the robustness of the shape factors reported to date, iii) the effect of shape is present at skewed piers although the associated coefficients remain in the narrow range of 1.0–1.2, and iv) for length–width ratios smaller than 4, the shape factor is of the same order of magnitude as the skew angle factor and should not be neglected.

    A scour monitoring system with a micro camera tracking the bed-level images is proposed in this study. Two image recognition algorithms have been developed to support the bed-level image tracking approach. Through the laboratory experiments of pier scour, this study demonstrates that the proposed system is able to accurately monitor the scour-depth evolution in real time. In addition, five commonly-used temporal scour models are employed to simulate scour-depth evolution and their results are compared with monitoring data. In general, the results indicate that the proposed scour monitoring system has the potential for further applications in the field.

  14. Apparent Sea Level Rise due to Loading of the Atlantic City Pier by Spectators Viewing (1929-1978) Diving Horses

    Galvin, C.

    2012-12-01

    Cyril Galvin, Coastal Engineer Springfield, Virginia 22150 USA Since 1911, the Steel Pier at Atlantic City, New Jersey, has been the site of the Atlantic City tide gauge, except for two intervals: 1911-1921 when the gauge was at the Million Dollar Pier in Atlantic City, and 1985-1991 when the gauge was at the Ventnor Fishing Pier (see Table 2, Zervos, 2009). By design, the Steel Pier was an amusement pier, and its most famous amusement was the Diving Horses: they dove bareback with a woman rider from a platform about 40 feet above sea level. They did that between 1929 and 1978, except for seven years - a post-war period, 1945 to 1953, when diving was suspended. The popularity of the diving horses is recorded on photos of crowds which occupied the bleachers at the seaward end of the pier to view the diving horses. By my count, the crowd pictured in the end papers of the book by Steve Liebowitz (2009) was about 4000 people. Typically, there were multiple shows daily. The weight of the crowd, estimated from the count of the crowd, was about 150 tons. This weight was loaded down on the piles by the crowd of spectators, and unloaded between shows of the diving horses. Most of the piles supporting the pier deck were imbedded in sand newly deposited since 1850. Using Atlantic City sea levels from the PSMSL data base and historical facts from Liebowitz (2009), and beginning with a 1912 start of the tide gauge, the apparent sea level rose at a rate of 3.1mm/yr until 1929 when the horses began diving. With the 1929 start of diving, the apparent sea level rise tripled, averaging 9.4 mm/yr until the act was suspended in 1945. In the 1945-1953 interval, when the horses did not dive (no crowds on the pier), apparent sea level fell (sea level FELL) at a rate of -1.6 mm/yr. The horses resumed diving in 1953, when the apparent sea level resumed at a rate of 4.0mm/yr. This 4.0 mm/yr is identical to the longtime sea level trend (1911-2006) from Zervos (2009) of 3.99mm/yr The history

    针对两种土层结构的可液化场地条件,采用2×2低承台群桩一独柱墩结构形式,完成了两个试验体的群桩-独柱墩结构地震反应振动台试验,很好地再现了自然地震触发场地液化及结构反应的各种宏观现象.结果表明,桩的最大加速度反应位置与地层结构关系密切且随场地液化发展而不断变化;低承台条件下,三层土场地较二层土场地对墩顶的加速度反应放大作用更显著;场地液化过程中,承台附近或液化与非液化土层分界处桩发生最大或较大动应变;低承台下,二层土场地中柱墩反应较小、桩反应较强,三层土场地中柱墩反应较强.%Two shaking table tests for seismic pile-soil-bridge interaction in liquefiable ground, with a low-cap 4-pile group and two typical soil profiles, were performed. The tests reproduced the macroscopic phenomena of soil liquefaction and seismic response of the structures in liquefiable ground. It is observed that the portions of the piles with maximum acceleration were in close contact with the soil layers and varied with the development of soil liquefaction. For the low-cap pile-supported bridge structure, the ground with three soil layers exerted more significant amplification effect on the acceleration response of the pier top than the ground with two soil layers. During soil liquefaction, the strains of the piles near the cap and the soil interface between liquefied soil and non-liquefied soil were comparatively greater than those at other positions. For the low-cap pile groups, the response of the pier was comparatively less significant and the pile strongly responded to the input motion of the ground with two soil layers, while the response of the pier was more significant under input motion of the ground with three soil layers.

    2014-01-01

    The hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier were researched. The effects of the prestressed tendon ratio, the longitudinal reinforcement ratio, and the stirrup reinforcement ratio on the hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier have been obtained with the fiber model analysis method. The analysis show some results about the prestressed concrete bridge pier. Firstly, greater prestressed tendon ratio and more longitudinal reinforcement can lead to more obvious pier's hysteresis loop "pinching effect," smaller residual displacement, and lower energy dissipation capacity. Secondly, the greater the stirrup reinforcement ratio is, the greater the hysteresis loop area is. That also means that bridge piers will have better ductility and stronger shear capacity. The results of the research will provide a theoretical basis for the hysteretic behavior analysis of the prestressed concrete pier.

    1995-05-01

    Full Text Available The fourteenth-century English poem Piers Plowman, by William Langland, tells of a quest for and pilgrimage to Truth, or God. The poem is lengthy and diffuse, and evidences Langland’s keen interest in philosophy, theology, politics, social conditions and apocalyptic literature, to mention only some areas. Underlying all, however, is a concern with the practical living-out of abstruse doctrinal concepts in everyday life. This essay explores certain characters and concepts which embody the doctrine and practice of charity, in order to demonstrate the interweaving of theory and practice which characterizes Langland at his best.

  20. Impact of bridge pier on the stability of ice jam

    Institute of Scientific and Technical Information of China (English)

    王军; 施发义; 陈胖胖

    2015-01-01

    River ice jam is one of the most important issues in rivers in cold regions during winter time. With the extra solid boundary due to the ice cover, the flow condition under ice-covered conditions is completely different from that of a open channel flow. The presence of bridge piers will further change the velocity field around the bridge piers. As a consequence, the formation and the accumulation of ice jams in the vicinity of the bridge pier will be affected. On the other side, the formation of an ice jam around the piers can cause extra turbulence to reduce the stability of a river bridge. The present study focuses on the stress analysis of the ice jam in the vicinity of a bridge pier. By developing a governing equation for describing the equilibrium state of an ice jam, the stability of the ice jam around bridge piers is analyzed and determined. As seen from the field data in literature, the stability estimations of an ice jam around bridge piers determined by the present method agree well with the field observations. Therefore, the proposed approach can be used for the prediction of the formation of ice jams around bridge piers.

    To mitigate scour around bridge piers, sacrificial piles are economic method where natural processes are involved. The arrangement should be such that scoured materials from the sacrificial piles should have enough volume to fill the scour hole created upstream of the pier in such a way that sediments are trapped inside the scour hole. This concept differs from earlier study made with sacrificial piles that mainly deals to reduce the strength of horseshoe vortex. To determine the effect of sacrificial piles for scour mitigation, alternative arrangements of piles were tested in front of a rectangular pier under clear-water condition and found that when the group of piles is placed at a distance of twice the projected width of the pier, for which percentage of blockage of the pier width is 60%, the scour volume can be reduced upto 61% while the maximum scour depth can be reduced upto 50%.

    为解决高墩大跨桥梁结构体系可靠度求解过程中失效模式复杂、极限状态方程无法显式表达等问题,提出一种基于支持向量机(SVM)分类技术的体系可靠度计算方法.该方法采用拉丁超立方抽样法产生样本库,通过重复筛选构造一个精确的SVM分类器函数(而不是构造功能函数本身的响应面函数),然后采用蒙特卡罗法进行数值模拟计算体系失效概率.以济邵高速公路逢石河特大桥为例验证了采用该方法计算高墩大跨桥梁体系可靠度的实用性,计算结果表明该桥体系可靠度满足设计要求.%To cope with the problems that the failure modes in the solving process of structural system reliability of high-rise pier and long span bridge are complicated and the limit state e-quations can not be displayed and expressed, a method for computation of the system reliability based on the support vector machine (SVM) classification technique is proposed. The proposed method can generalize the sample bank, using the Latin hypercube sampling method and can construct a precise SVM classifier function (rather than the response surface function of the structure function itself) by repeated screening and the numerical simulation and computation of the system failure probability are accordingly carried out, using the Monte Carlo method. By way of example of the Fengshi River Bridge on Jiyuan-Shaoyuan Expressway, the practicability of the method for computation of the system reliability of the high-rise pier and long span bridge is verified and the results of the computation prove that the system reliability of the bridge can meet the design requirements

    2005-01-01

    This paper presents a laboratory study on bridge pier protection with surface guide panels (SGP) in clear-water experiments. The SGP is installed by piercing a set of two vertical panels partially into the water, with some interior angle and leading opening, setting at a distance ahead of the protected pier. The suitable installation of the SGP can effectively adjust the flow pattern to reduce the downflow motion and the horseshoe vortex ahead of the pier. We consider some dominant factors to set up SGP for pier protection, including the interior angle θ, leading opening Ow, distance between panel and pier L, submerged depth of panel Pd, pier diameter D and water depth H. After evaluation of these parameters through laboratory tests, the optimal setup conditions of θ=60o, Ow/D=0.1~0.2, L/D=2~2.5 and Pd/H=0.7 are determined. Under these conditions, the usage of SGP leads to a best performance on decrement of the maximum scour depth at pier up to 90% with ignorable side effects on the SGP scour.

    Kinoshita K.

    2013-01-01

    Full Text Available Fatigue retrofit works have been conducted on severely fatigue damaged beam-to-column connections of existing steel frame bridge piers in Japan. It is clear that retrofit works provides additional stiffness but the significance on the seismic behavior of steel frame piers is not clear. Since fatigue retrofit works have become prevalent, the effect of fatigue retrofit works on the seismic behavior of steel frame piers need to be understood. The objective of this study is therefore to investigate these effects of the retrofit work, especially installation of bolted splices, which is the most common technique. Elasto-plastic finite element earthquake response analyses were carried out. It is shown that the existence of bolted splices may increase seismic demand on the piers when plastic hinge zone is located on the beam. In addition, longer bolted splices using low yield strength steel are proposed to overcome this problem and are shown to give beneficial effects.

    Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures. Termed rocking isolation, this new seismic design philosophy is investigated through a series of dynamic centrifuge experiments on properly scaled models of a modern reinforced concrete (RC) bridge pier. The experimental method reproduces the nonlinear and inelastic response of both the soil-footing interface and the structure. To this end, a novel scale model RC (1:50 scale) that simulates reasonably well the elastic response and the failure of prototype RC elements is utilized, along with realistic representation of the soil behavior in a geotechnical centrifuge. A variety of seismic ground motions are considered as excitations. They result in consistent demonstrably beneficial performance of the rocking-isolated pier in comparison with the one designed conventionally. Seismic demand is reduced in terms of both inertial load and deck drift. Furthermore, foundation uplifting has a self-centering potential, whereas soil yielding is shown to provide a particularly effective energy dissipation mechanism, exhibiting significant resistance to cumulative damage. Thanks to such mechanisms, the rocking pier survived, with no signs of structural distress, a deleterious sequence of seismic motions that caused collapse of the conventionally designed pier. © 2014 The Authors Earthquake Engineering & Structural Dynamics Published by John Wiley & Sons Ltd.

  19. Evaluation of pier-scour measurement methods and pier-scour predictions with observed scour measurements at selected bridge sites in New Hampshire, 1995-98

    Boehmler, Erick M.; Olimpio, Joseph R.

    2000-01-01

    In a previous study, 44 of 48 bridge sites examined in New Hampshire were categorized as scour critical. In this study, the U.S. Geological Survey (USGS) evaluated pier-scour measurement methods and predictions at many of these sites. This evaluation included measurement of pier-scour depths at 20 bridge sites using Ground- Penetrating Radar (GPR) surveys. Pier scour was also measured during floods by teams at 5 of these 20 sites. At 4 of the 20 sites, fixed instruments were installed to monitor scour. At only one bridge site investigated by a team was any pier scour measurable during a flood event. A scour depth of 0.7 foot (0.21 m) was measured at a pier in the channel at the State Route 18 bridge over the Connecticut River in Littleton. Measurements made using GPR and (or) fixed instruments indicated pier scour for six sites. The GPR surveys indicated scour along the side of a pier and further upstream from the nose of a pier that was not detected by flood-team measurements at two sites. Most pier-scour equations selected for this examination were reviewed and published in previous scour investigations. Graphical comparison of residual pier-scour depths indicate that the Shen equation yielded pier-scour depth predictions closest to those measured, without underestimating. Measured depths of scour, however, were zero feet for 14 of the 20 sites. For the Blench-Inglis II equation and the Simplified Chinese equation, most differences between measured and predicted scour depths were within 5 feet. These two equations underpredicted scour for one of six sites with measurable scour. The underprediction, however, was within the resolution of the depth measurements. The Simplified Chinese equation is less sensitive than other equations to velocity and depth input variables, and is one of the few empirical equations to integrate the influence of flow competence, or a measure of the maximum streambed particle size that a stream is capable of transporting, in the

  2. Numerical Hybrid Simulation Modeling Verification for a Curved 3-Pier Bridge (Investigation of Combined Actions on Reinforced Concrete Bridge Piers (CABER Project

    Directory of Open Access Journals (Sweden)

    Adel Abdelnaby

    2013-06-01

    Full Text Available Reinforced concrete bridge piers are subjected to complex loading conditions under earthquake ground motions. Bridge geometric irregularities and asymmetries result in combined actions imposed on the piers as a combination of displacements and rotations in all six degrees of freedom at the pier-deck juncture. Existing analytical tools have proven their inadequacy in representing the actual behavior of piers under these combined actions, particularly in their inelastic range. The objective of this investigation is to develop a fundamental understanding of the effects of these combined actions on the performance of RC piers and the resulting system response. This paper describes a part of the CABER project that verifies the numerical hybrid simulation of the curved bridge. In this part two models were introduced, a whole model and a sub-structured hybrid model. The whole model was established using the Zeus-NL analysis platform, which is capable of performing inelastic nonlinear response history analysis of the whole curved bridge. The hybrid model was divided into three modules which comprised the deck, left and right piers, and the middle pier of the bridge. The three modules were modeled by Zeus-NL as a static analysis module interface. The simulation coordinator (SimCor software was utilized to communicate between these modules using a Pseudo-Dynamic time integration scheme. Results obtained from both models were compared and conclusions were drawn.

    An analytical method to study the seismic response of a bridge pier supported on a rigid caisson foundation embedded in a deep soil stratum underlain by a homogeneous half space is developed. The method reproduces the kinematic and inertial responses, using translational and rotational distributed Winkler springs and dashpots to simulate the soil-caisson interaction. Closed-form solutions are given in the frequency domain for vertical harmonic S-wave excitation. Comparison with results from finite element (FE) analysis and other available solutions demonstrates the reliability of the model. Results from parametric studies are given for the kinematic and inertial responses. The modification of the fundamental period and damping ratio of the bridge due to soil-structure interaction is graphically illustrated.

    Lee, Eleanor; Selkowitz, Stephen

    2009-12-31

    Building facades directly influence heating and cooling loads and indirectly influence lighting loads when daylighting is considered, and are therefore a major determinant of annual energy use and peak electric demand. Facades also significantly influence occupant comfort and satisfaction, making the design optimization challenge more complex than many other building systems.This work focused on addressing significant near-term opportunities to reduce energy use in California commercial building stock by a) targeting voluntary, design-based opportunities derived from the use of better design guidelines and tools, and b) developing and deploying more efficient glazings, shading systems, daylighting systems, facade systems and integrated controls. This two-year project, supported by the California Energy Commission PIER program and the US Department of Energy, initiated a collaborative effort between The Lawrence Berkeley National Laboratory (LBNL) and major stakeholders in the facades industry to develop, evaluate, and accelerate market deployment of emerging, high-performance, integrated facade solutions. The LBNL Windows Testbed Facility acted as the primary catalyst and mediator on both sides of the building industry supply-user business transaction by a) aiding component suppliers to create and optimize cost effective, integrated systems that work, and b) demonstrating and verifying to the owner, designer, and specifier community that these integrated systems reliably deliver required energy performance. An industry consortium was initiated amongst approximately seventy disparate stakeholders, who unlike the HVAC or lighting industry, has no single representative, multi-disciplinary body or organized means of communicating and collaborating. The consortium provided guidance on the project and more importantly, began to mutually work out and agree on the goals, criteria, and pathways needed to attain the ambitious net zero energy goals defined by California and

  5. Experimental study on the width of the turbulent area around bridge pier

    2007-01-01

    At present, the method of calculating the turbulent flow width around the bridge pier is not given in the "Standard for Inland River Navigation" (GB50139-2004) in China, and the bridge designer usually increases the bridge span in order to ensure the navigation safety, which increases both of the structural design difficulty and the project investments. Therefore, it is extremely essential to give a research on the turbulent flow width around the bridge pier. Through the experiments of the fixed bed and the mobile bed, the factors influencing the turbulent flow width around the bridge pier have been analyzed, such as the approaching flow speed, the water depth, the angles between the bridge pier and the flow direction, the sizes of bridge pier, the shapes of the bridge pier, and the scouring around the bridge pier, etc. Through applying the dimension analytic method to the measured data, the formula of calculating the turbulent flow width around the bridge pier is then inferred.

    2007-01-01

    According to the engineering features of higher pile-column bridge pier in mountainous area, a clamped beam mechanical model was set up by synthetically analyzing the higher pile-column bridge pier buckling mechanism. Based on the catastrophe theory, the cusp catastrophe model of higher pile-column bridge pier was established by the determination of its potential function and bifurcation set equation, the necessary instability conditions of high pile-column bridge pier were deduced, and the determination method for column-buckling and lateral displacement of high pile-column bridge pier was derived. The comparison between the experimental and calculated results show that the calculated curves agree with testing curves and the method is reasonable and effective.

    2016-12-01

    Full Text Available The ductility of prestressed concrete pier is studied based on response surface methodology. Referring to the pervious prestressed concrete pier, based on Box-Behnken design, the ductility of 25 prestressed concrete piers is calculated by numerical method. The relationship between longitudinal reinforcement ratio, shear reinforcement ratio, prestressed tendon quantity, concrete compressive strength and ductility factor is gotten. The influence of the longitudinal reinforcement ratio, the shear reinforcement ratio, the prestressed tendon quantity and concrete compressive strength to curvature ductility is discussed. Then the ductility regression equation is deduced. The result showed that the influence of the prestressed tendon quantity to the ductility of prestressed concrete pier is significant. With the increasing of the prestressed tendon quantity, the curvature ductility curved reduces. With the increasing of shear reinforcement ratio and compressive strength of concrete, the curvature ductility increases linearly. And the influence of the longitudinal reinforcement ratio to ductility of the prestressed concrete pier is insignificant.

  12. Mathematical Modeling of Local Scour at Slender and Wide Bridge Piers

    Directory of Open Access Journals (Sweden)

    Youssef I. Hafez

    2016-01-01

    Full Text Available Most existing equations for predicting local scour at bridge piers suffer from overprediction of the scour depths which results in higher foundation costs. To tackle this problem, a mathematical model for predicting bridge pier scour is developed herein based on an energy balance theory. The present study equation was compared to commonly used bridge scour equations using scour field data in USA. The developed equation has several advantages among which we have the following: it adds to the understanding of the physics of bridge pier scour, is valid for slender and wide piers, does not suffer from overprediction of scour depths, addresses clear water and live bed scour, and includes the effects of various characteristics of the bed material such as specific gravity (or density, porosity, size, and angle of repose. In addition, the developed equation accounts for the debris effect and aids in the design of scour mitigation methods such as collars, side bars, slots, and pier protective piles.

    2016-01-01

    A fundamental principle in the safe design of bridge piers is to estimate maximum scour depth. As such, many researchers devoted their efforts to study the phenomenon of scour around bridge piers and to present relationships to estimate maximum scour depth. In the current research, scour around circular bridge piers with two different diameters and different inclination angles toward downstream has been investigated experimentally under clear water and different discharges. The obtained results revealed that increase in the inclination angle leads to a significant decrease in the scour depth, dimensions of sediment ridge and scour hole. Moreover, by comparing the data obtained from vertical bridge pier and well-known relationships, a relationship having the most agreement with the results was selected and modified to estimate equilibrium scour depth around inclined piers.

  15. Study on Repaired Earthquake-Damaged Bridge Piers under Seismic Load

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The concrete bridge pier damaged during earthquakes need be repaired to meet the design standards. Steel tube as a traditional material or FRP as a novel material has become popular to repair the damaged reinforced concrete (RC bridge piers. In this paper, experimental and finite element (FE studies are employed to analyze the confinement effectiveness of the different repair materials. The FE method was used to calculate the hysteretic behavior of three predamaged circle RC bridge piers repaired with steel tube, basalt fiber reinforced polymer (BFRP, and carbon fiber reinforced polymer (CFRP, respectively. Meanwhile, the repaired predamaged circle concrete bridge piers were tested by pseudo-static cyclic loading to study the seismic behavior and evaluate the confinement effectiveness of the different repair materials and techniques. The FE analysis and experimental results showed that the repaired piers had similar hysteretic curves with the original specimens and all the three repair techniques can restore the seismic performance of the earthquake-damaged piers. Steel tube jacketing can significantly improve the lateral stiffness and peak load of the damaged pier, while the BFRP and CFRP sheets cannot improve these properties due to their thin thickness.

  16. Reduction of scour around bridge piers using a modified method for vortex reduction

    Directory of Open Access Journals (Sweden)

    Entesar A.S. EL-Ghorab

    2013-09-01

    Full Text Available The current study presents a modified method to reduce the scour depth in front of the bridge piers. The idea of this method is based on reducing the stagnation of the flow and vortex formation in front of the pier. Therefore, the pressure difference around the pier is used for driving the flow through an arrangement of openings in front and connected to the openings along the pier’s side. A test program was planned using an experimental flume at the Hydraulics Research Institute (HRI and three hundred thirty six runs were conducted. Three different pier shapes, circular, square, and rectangular, provided with different openings arrangement and vertical spacing are tested. This method showed that the scour depth is reduced by 45% and also the volume of the scoured material is decreased up to 64%. These results were obtained using opening diameter of 20% of the pier width (w and vertical spacing equals the pier width (w. Also, a dimensionless regression equation was developed based on the obtained results. These findings when implemented in the field can easily safeguard the bridge piers and dramatically reduce the maintenance efforts and costs as well as improve the hydraulic performance of the water structure.

  17. Analysis of Water Flow Pressure on Bridge Piers considering the Impact Effect

    Directory of Open Access Journals (Sweden)

    Yin-hui Wang

    2015-01-01

    Full Text Available In order to investigate the effects of water current impact and fluid-structure interaction on the bridge piers, the mechanism of water flow impact on the bridge pier is firstly studied. Then a finite element model of a bridge pier is established including the effects of water flow impact as well as the water circumferential motion around the pier. Comparative study is conducted between the results of water impact effect, fluid-structure coupling effect, theoretical analysis, and also the results derived using the formulas specified in the design codes home and abroad. The results show that the water flow force calculated using the formulas provided by the codes should be multiplied by an impact amplifier to account for the effect of flood impact on the bridge pier. When the flood flows around the pier, the fluid-structure coupling effect on the bridge pier can be neglected. The method specified in the China guidelines of General Code for Design of Highway Bridges and Culverts tends to provide a larger result of the water flow force.

  18. Experimental Study on a Self-Centering Earthquake-Resistant Masonry Pier with a Structural Concrete Column

    Directory of Open Access Journals (Sweden)

    Lijun Niu

    2017-01-01

    Full Text Available This paper proposes a slotting construction strategy to avoid shear behavior of multistory masonry buildings. The aspect ratio of masonry piers increases via slotting between spandrels and piers, so that the limit state of piers under an earthquake may be altered from shear to rocking. Rocking piers with a structural concrete column (SCC form a self-centering earthquake-resistant system. The in-plane lateral rocking behavior of masonry piers subjected to an axial force is predicted, and an experimental study is conducted on two full-scale masonry piers with an SCC, which consist of a slotting pier and an original pier. Meanwhile, a comparison of the rocking modes of masonry piers with an SCC and without an SCC was conducted in the paper. Experimental verification indicates that the slotting strategy achieves a change of failure modes from shear to rocking, and this resistant system with an SCC incorporates the self-centering and high energy dissipation properties. For the slotting pier, a lateral story drift ratio of 2.5% and a high displacement ductility of approximately 9.7 are obtained in the test, although the lateral strength decreased by 22.3% after slotting. The predicted lateral strength of the rocking pier with an SCC has a margin of error of 5.3%.

    2016-09-01

    This study aims to analyze seismic damage of reinforced outlet piers of arch dams by the nonlinear finite element (FE) sub-model method. First, the dam-foundation system is modeled and analyzed, in which the effects of infinite foundation, contraction joints, and nonlinear concrete are taken into account. The detailed structures of the outlet pier are then simulated with a refined FE model in the sub-model analysis. In this way the damage mechanism of the plain (unreinforced) outlet pier is analyzed, and the effects of two reinforcement measures (i.e., post-tensioned anchor cables and reinforcing bar) on the dynamic damage to the outlet pier are investigated comprehensively. Results show that the plain pier is damaged severely by strong earthquakes while implementation of post-tensioned anchor cables strengthens the pier effectively. In addition, radiation damping strongly alleviates seismic damage to the piers.

    2016-01-01

    Full Text Available This paper investigates the seismic performance of posttensioned concrete piers with external viscoelastic dampers to improve the energy dissipation capacity of this type of structure. An installation scheme for viscoelastic dampers on bridge piers is proposed, and the mechanical models of the damper are analyzed according to the installation scheme. By attaching the viscoelastic dampers to the posttensioned bridge piers, the analytical model of the hybrid system is established using the OpenSees finite element analysis package. Cyclic behavior and time history analyses are conducted on a posttensioned bridge with and without viscoelastic dampers using the established finite element model. The analysis results indicate that the viscoelastic dampers can effectively improve the seismic performance of the bridge structures with posttensioned piers.

    2011-12-01

    An experimental study was conducted to investigate the feasibility of a proposed rapid repair technique for severely earthquake-damaged bridge piers with flexural-shear failure mode. Six circular pier specimens were first tested to severe damage in flexural-shear mode and repaired using early-strength concrete with high-fluidity and carbon fiber reinforced polymers (CFRP). After about four days, the repaired specimens were tested to failure again. The seismic behavior of the repaired specimens was evaluated and compared to the original specimens. Test results indicate that the proposed repair technique is highly effective. Both shear strength and lateral displacement of the repaired piers increased when compared to the original specimens, and the failure mechanism of the piers shifted from flexural-shear failure to ductile flexural failure. Finally, a simple design model based on the Seible formulation for post-earthquake repair design was compared to the experimental results. It is concluded that the design equation for bridge pier strengthening before an earthquake could be applicable to seismic repairs after an earthquake if the shear strength contribution of the spiral bars in the repaired piers is disregarded and 1.5 times more FRP sheets is provided.

    2017-03-01

    Full Text Available Introduction: Bridges are certainly one of the most important structures but costly service elements in a transport system. The bridges are very required to access the damaged areas in emergency situations such as floods and earthquakes. Scour around the foundations of bridge piers exposed to the flowing water than can destroy the bridge itself is a subject of major concern. Flow pattern is known as responsible for all changes in stream bed. Any obstacle in the channel can form new flow patterns causing additional shear stress exerted on the bed than the equilibrium condition of the absence of the obstacle. Appropriate shaping of flow pattern and proper selecting of pier geometry and the location of bridge piers can be one of the proper methods in reduction of scour amount which is the main subject of the present study. Materials and Methods: Inclined bridge group pier is a type of bridges with modern geometry based on development in building technology of structures. Many of these bridges have been built all around the world and the 8th bridge built crossing the Karun River in Ahvaz is a sample of the Iranian ones considered in this research. Hydrodynamic behavior of flow is investigated around the inclined bridge group pier settled on foundation using the FLOW-3D numerical model. Inclined bridge group pier investigated in this study, includes two rectangular piers which are 2.5 cm long and 3.5 cm wide and set in an angle of 28 degree on rectangular foundation which is 16 cm long and 10 cm wide and installed in three different foundation levels namely at, above and below the bed levels. The physical model of prototype pier considered in this study was constructed to the scale of 1:190 of the Ahvaz 8th bridge. In order to verify the accuracy of the numerical model, velocity data obtained from image processing technique were used. Results and Discussion: Due to non- linearity and interactions between various phenomena involved, flow pattern

    In recent earthquakes,a large number of reinforced concrete (RC) bridges were severely damaged due to mixed flexure-shear failure modes of the bridge piers.An integrated experimental and finite element (FE) analysis study is described in this paper to study the seismic performance of the bridge piers that failed in flexure-shear modes.In the first part,a nonlinear cyclic loading test on six RC bridge piers with circular cross sections is carried out experimentally.The damage states,ductility and energy dissipation parameters,stiffness degradation and shear strength of the piers are studied and compared with each other.The experimental results suggest that all the piers exhibit stable flexural response at displacement ductilities up to four before exhibiting brittle shear failure.The ultimate performance of the piers is dominated by shear capacity due to significant shear cracking,and in some cases,rupturing of spiral bars.In the second part,modeling approaches describing the hysteretic behavior of the piers are investigated by using ANSYS software.A set of models with different parameters is selected and evaluated through comparison with experimental results.The influences of the shear retention coefficients between concrete cracks,the Bauschinger effect in longitudinal reinforcement,the bond-slip relationship between the longitudinal reinforcement and the concrete and the concrete failure surface on the simulated hysteretie curves are discussed.Then,a modified analysis model is presented and its accuracy is verified by comparing the simulated results with experimental ones.This research uses models available in commercial FE codes and is intended for researchers and engineers interested in using ANSYS software to predict the hysteretic behavior of reinforced concrete structures.

Then, a modified analysis model is presented and its accuracy is verified by comparing the simulated results with experimental ones. This research uses models available in commercial FE codes and is intended for researchers and engineers interested in using ANSYS software to predict the hysteretic behavior of reinforced concrete structures.

    Concrete bridge piers are a common structural element employed in the design of bridges and elevated roadways. In order to ensure adequate behavior under earthquake-induced displacements, extensive reinforcement detailing in the form of closely spaced ties or spirals is necessary, leading to congestion problems and difficulties during concrete casting. Further, costly repairs are often necessary in bridge piers after a major earthquake which in some cases involve the total or partial shutdown of the bridge. In order to increase the damage tolerance while relaxing the transverse reinforcement requirements of bridge piers, the use of high-performance fiber reinforced cementitious composites (HPFRCC) in earthquake-resistant bridge piers is explored. HPFRCCs are a relatively new class of cementitious material for civil structures with tensile strain-hardening behavior and high damage tolerance. To monitor the behavior of this new class of material in the field, low-cost wireless monitoring technologies will be adopted to provide HPFRCC structural elements the capability to accurately monitor their performance and health. In particular, the computational core of a wireless sensing unit can be harnessed to screen HPFRCC components for damage in real-time. A seismic damage index initially proposed for flexure dominated reinforced concrete elements is modified to serve as an algorithmic tool for the rapid assessment of damage (due to flexure and shear) in HPFRCC bridge piers subjected to large shear reversals. Traditional and non-traditional sensor strategies of an HPFRCC bridge pier are proposed to optimize the correlation between the proposed damage index model and the damage observed in a circular pier test specimen. Damage index models are shown to be a sufficiently accurate rough measure of the degree of local-area damage that can then be wirelessly communicated to bridge officials.

  8. HYDRAULIC CHARACTERISTICS OF BOTTOM UNDERLAY-TYPE PIER FOR WATER-WING CONTROL

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    The pier, placed at the outlet of the pressure flow section, is an effective design to deal with the problems of the manufacture and operation of the gates for a discharge tunnel with high water head. It is crucial to control the water-wing, induced by this type of the pier. Through observing the phenomena of the water-wing, the reason of the water-wing inception, i.e., the concave of the flow surface, was presented, and a type of the new pier with bottom underlay was designed. The hydraulic characteristics of the pier, including the variations of the water-wing features, both length and height, with the water head, as well as with the concave depth, and with the height of the bottom underlay, and the variations of the concave depth with the height of the bottom underlay, were investigated by physical model experiments. The results show that the approach of the modification of the concave through the structures with the bottom underlay-type pier is remarkably effective in the water-wing control.

    Full Text Available Based on the previous research work, a new idea is proposed for analyzing the impact of solar radiation on the substructure of bridges. Investigation is conducted in the thermodynamic phenomena and temperature stress of a dual-column pier. Research is led to the thermal conductivity of concrete structure and the values of the environmental parameters under solar radiation. An analytical code is written for the thermal analysis of the dual-column pier using the parametric modeling function of FE software, by means of which the temperature distribution of the bridge structure is computed under solar radiation. Using the thermal analytical results, the temperature stress of the dual-column pier is further calculated. The results tell that the temperature gradient distribution curve inside the concrete of the pier fits favorably the curve defined in the design specification and coincides quite well with real situation, which verifies the new idea proposed in this paper. Under the solar radiation which is a time-variable nonlinear temperature load to the bridge, the maximum principal stress is found at the corner of the pier with the sign of negative, which is believed to threaten the safety of the substructure of bridge and is necessary to arouse emphasis.

    Full Text Available This study investigated the seismic behavior of glass fiber reinforced polymer (GFRP strengthened hollow rectangular bridge piers. Cyclic testing of reinforced concrete (RC piers retrofitted with GFRP was carried out under constant axial loading and lateral bending. The failure characteristics, flexural ductility, dissipated energy, and hysteretic behaviors, were analyzed based on experimental results. A simplified GFRP-confined concrete model is developed by considering effective strength coefficient and area distribution ratio of GFRP sheets. The results indicate that the failure modes and damage region would be changed and the ductility and dissipated energy of the GFRP-strengthened hollow rectangular bridge piers were improved greatly but not much improvement for the lateral load capacity. The analytical results of the force-displacement hysteretic loops based on the GFRP-confined concrete model developed in this paper agreed well with the experimental data.

  11. Realistic modelling of the effects of asynchronous motion at the base of bridge piers

    2002-01-01

    Frequently long-span bridges provide deep valley crossings, which require special consideration due to the possibility of local amplification of the ground motion as a consequence of topographical irregularities and local soil conditions. This does in fact cause locally enhanced seismic input with the possibility for the bridge piers to respond asynchronously. This introduces special design requirements so that possible out-of-phase ground displacements and the associated large relative displacements of adjacent piers can be accommodated without excessive damage. Assessment of the local variability of the ground motion due to local lateral heterogeneities and to attenuation properties is thus crucial toward the realistic definition of the asynchronous motion at the base of the bridge piers. We illustrate the work done in the framework of a large international cooperation to assess the importance of non-synchronous seismic excitation of long structures. To accomplish this task we compute complete synthetic acc...

    Centre Pier is a 3.9 ha property owned by the Commissioners of the Port Hope Harbour in the Municipality of Port Hope, Ontario, Canada. It is centrally located on the Port Hope waterfront and is bounded on the west by the Port Hope Harbour, on the east by the Ganaraska River, on the south by Lake Ontario, and on the north by a railway corridor. The property is currently leased by the Commissioners of the Port Hope Harbour to the Cameco Corporation which owns the four onsite building that are used as warehouse space for their uranium conversion facility located on the western side of the Harbour. Remediation of this site forms part of the Port Hope Project being undertaken by Atomic Energy of Canada Limited (AECL) and Public Works and Government Services Canada (PWGSC) as part of the Port Hope Area Initiative (PHAI). Soil impacts include radiological, metals and petroleum hydrocarbons resulting from long term historical industrial use. Radiological impacts in soil extend across most of the site primarily within the upper metre of fill. Metals-contaminated soil is present across the entire site in the underlying fill material. The metals-contaminated fill extends to a maximum depth of 2.0 m below grade at the north end of the site which is underlain by peat. However, the metals-contaminated soil could extend to the top of the bedrock on the remainder of the site. Based on the elevation of the bedrock in the adjacent river and Harbour Basin, the metals-contaminated soil may extend to a depth of 5.6 m or 6.5 m below existing grade. Petroleum-contaminated soil is present on the southeast side of the site, where a storage tank farm was previously located. Challenges include: - The complex history of the site both relating to site use and Pier construction. Pier development began in the 1800's and was undertaken by many different entities. Modifications and repairs were made over the years resulting in several different types of Pier walls and fill that must be

    In this article, the turbulent flow field and the scouring mechanism around a circular pier were numerically investigated using the Large Eddy Simulation (LES) method for three scouring holes. The effects of the bottom topographies on the flow structure were studied in detail. The results show that at the downstream of the pier, as the scouring depth increases, the bed shear stress decreases and approaches to the undisturbed shear stress, however, the turbulent intensity, the fluctuating pressure, and the vertical pressure gradient increase gradually.

    2005-01-01

    In construction of high dams, design of a middle-pier, placed in a discharge tunnel to divide it into two parts, is a better choice that could breakthrough the limits of the manufacture and operation of the gate due to the high head to it. However, cavitation and water-wing, a kind of flow striking the top and side walls of the tunnel, induced by the middle-pier, may take place and bring about bad effects on operation of the tunnel. The experiments of the six comparing plans were conducted, consisting of atmospheric and vacuum tank models, and the interesting areas included relationships between discharges and reservoir levels, measurements of side wall pressures, comparisons of water-wing states for the various middle-piers, estimations of the incipient cavitation numbers and the flow cavitation numbers, and analyses of cavitation characteristics for the tunnel. A kind of new bodily form of middle-pier was developed. Water-wing states were better improved and non-cavitation conditions were satisfied.

  2. Effect of downward seepage on turbulent flow characteristics and bed morphology around bridge piers

    2017-03-01

    In this work, experimental investigations have been pursued to analyse the influence of downward seepage on the turbulent characteristics of flow and corresponding changes in vortex structure around circular bridge pier in alluvial channel. Experiments were conducted in sand bed channel with circular piers of different sizes for no seepage, 10% seepage and 20% seepage cases. The measurement of turbulent flow statistics such as velocity and Reynolds stresses is found to be negative within the scour hole at upstream of the pier whereas application of downward seepage retards the reversal of the flow causing a decrement in the velocity and Reynolds stresses. Higher Reynolds shear stress prevails at the downstream side because of the production of wake vortices. Contribution of all bursting events to the total Reynolds shear stress production has been observed to increase with downward seepage. The analysis of integral scale suggest that size of eddies increases with seepage, which is responsible for increase in particle mobility. Initially rate of scouring is more which abatements gradually with expanding time as well as with the increased of downward seepage. Presence of downward seepage reduces the depth and length of vortex and shifts towards downstream side of the pier.

  6. A study on ship impacting a flexible crashworthy device for protecting bridge pier

    Directory of Open Access Journals (Sweden)

    Yang Liming

    2015-01-01

    Full Text Available As the accident of a vessel impacting a bridge pier will cause serious disaster, such as destroyed bridge, sinking ship and polluting environment, the technology and method to protect bridge pier from ship collision have been widely investigated recently. Due to the huge kinetic energy of large-tonnage ship and the short time duration in the collision, the studies involve impact mechanics. A developed flexible crashworthy device has been developed to protect bridges, which consists of an outer steel-periphery, an inner steel-periphery and the rubber coating SWRCs(soft elements installed between them. When the SWRC crashworthy device is installed, the collision duration under low impact force is prolonged due to its high compliance, which results in the ship having enough time to turn its navigation direction and most of the remainder kinetic energy being carried off by the turned away ship. Consequently, both impact forces on the ship and on the bridge pier decrease markedly. This is the key reason as to why the SWRC crashworthy device can avoid the destruction of both the bridge and the ship. Based on our results of theoretical studies and numerical simulations, the present paper will propose an experiment-adopted a real ship to impact a flexible crashworthy device. The collision test has been performed 12 times with different speed, carrying capacity, and impact angle of the ship. After the experiments, the ship, flexible crashworthy device and the pier are not damaged. The experiments show that the flexible crashworthy device can turn away the impact ship, so that the ship moves along the outer part of the device, which reduces the ship impact force on the bridge pier obviously. It not only protects bridges but also avoids the damage to ships.

  10. Seismic Behavior and Force-Displacement Characterization of Neotype Column-Slab High Piers

    Directory of Open Access Journals (Sweden)

    YanQun Zhou

    2014-01-01

    Full Text Available The seismic behavior and plasticity spreading of a neotype column-slab high pier are researched in this paper. Four scale model tests of a web slab with two boundary columns are carried out under cyclic inelastic lateral displacements simulating seismic response. The test results show that the neotype column-slab high pier has strong and stable bearing capacity, good ductility, and energy dissipation capacity. The experimental values pertaining to the spread of plasticity are derived. An approach for deriving the spread of plasticity analytically is deduced and applied to the four tests. This method accurately assesses a pier’s spread of plasticity for most ductility levels. At nearly all ductility levels, the mean difference between analytical assessments of the spread of plasticity and results from 4 large-scale tests is 12% with a 9% coefficient of variation.

    The energy dissipation of X-shaped flaring gate piers ahead of a stepped spillway was adopted in the Suofengying Hydroplant. Under the circumstance that the first step is higher than others, at the step surface an aerated cavity occured behind piers. The interaction of the weir head, the elevation difference between crest and chamber outlet, the first step height, the slopes of weir end and step, and the size of cavity, was investigated, the expression was derived to characterize their relationship, and the corresponding curves were plotted. The comparison of the calculated and simulated results with the measured data was performed. When the slopes of step and weir end are equivalent, the relative height difference between the first and second steps becomes the main factor influencing the aerated cavity. These findings may be useful in practical applications.

  13. Pier and contraction scour prediction in cohesive soils at selected bridges in Illinois

    Science.gov (United States)

    Straub, Timothy D.; Over, Thomas M.

    2010-01-01

    This report presents the results of testing the Scour Rate In Cohesive Soils-Erosion Function Apparatus (SRICOS-EFA) method for estimating scour depth of cohesive soils at 15 bridges in Illinois. The SRICOS-EFA method for complex pier and contraction scour in cohesive soils has two primary components. The first component includes the calculation of the maximum contraction and pier scour (Zmax). The second component is an integrated approach that considers a time factor, soil properties, and continued interaction between the contraction and pier scour (SRICOS runs). The SRICOS-EFA results were compared to scour prediction results for non-cohesive soils based on Hydraulic Engineering Circular No. 18 (HEC-18). On average, the HEC-18 method predicted higher scour depths than the SRICOS-EFA method. A reduction factor was determined for each HEC-18 result to make it match the maximum of three types of SRICOS run results. The unconfined compressive strength (Qu) for the soil was then matched with the reduction factor and the results were ranked in order of increasing Qu. Reduction factors were then grouped by Qu and applied to each bridge site and soil. These results, and comparison with the SRICOS Zmax calculation, show that less than half of the reduction-factor method values were the lowest estimate of scour; whereas, the Zmax method values were the lowest estimate for over half. A tiered approach to predicting pier and contraction scour was developed. There are four levels to this approach numbered in order of complexity, with the fourth level being a full SRICOS-EFA analysis. Levels 1 and 2 involve the reduction factors and Zmax calculation, and can be completed without EFA data. Level 3 requires some surrogate EFA data. Levels 3 and 4 require streamflow for input into SRICOS. Estimation techniques for both EFA surrogate data and streamflow data were developed.

By a numerical example, RC double-column piers with different lateral force distribution pattern, different heights and different reinforcement ratio were analyzed. The results show that the analysis results for lower piers of simple supported beam bridges are approximately identical under different lateral force distribution, while with the increase of pier height and longitudinal ratio of reinforcement, the displacement ductility factor is reduced.

    A multimedia version of Piers-Harris Children's Self-Concept Scale 2 (Piers-Harris 2) was created with audio and cartoon animation to facilitate the measurement of self-concept among younger children. This study aimed to assess the psychometric qualities of the computer version of Piers-Harris 2 scores, examine its score equivalence with the paper-and-pencil version, and survey the respondent preference of the two versions. Two hundred and forty eight Taiwanese students from the first to fourth grade were recruited. In regard to the psychometric properties, high internal consistency (α = .91) was found for the total score of multimedia Piers-Harris 2. High interscale correlations (.77 to .83) of the multimedia Piers-Harris 2 scores and the results of confirmatory factor analysis suggested the multimedia Piers-Harris 2 contained good structural characteristics. The scores of the multimedia Piers-Harris 2 also had significant correlations with the scores of the Elementary School Children's Self Concept Scale. The equality of convergence and criterion-related validities of Piers-Harris 2 scores for the multimedia and paper-and-pencil versions and the results of ICCs between the scores of the multimedia and paper-and-pencil Piers-Harris 2 suggested their high level of equivalence. Participants showed more positive attitudes towards the multimedia version.

In regard to the psychometric properties, high internal consistency (α = .91 was found for the total score of multimedia Piers-Harris 2. High interscale correlations (.77 to .83 of the multimedia Piers-Harris 2 scores and the results of confirmatory factor analysis suggested the multimedia Piers-Harris 2 contained good structural characteristics. The scores of the multimedia Piers-Harris 2 also had significant correlations with the scores of the Elementary School Children's Self Concept Scale. The equality of convergence and criterion-related validities of Piers-Harris 2 scores for the multimedia and paper-and-pencil versions and the results of ICCs between the scores of the multimedia and paper-and-pencil Piers-Harris 2 suggested their high level of equivalence. Participants showed more positive attitudes towards the multimedia version.

    Full Text Available This article offers some reflections about Pier Silverio Leicht’s position in the context of medieval italian studies. Leicht (1874-1956 belonged to the great generation of historians and law historians born in the Seventies of 19th century, but he maintained a specific profile as an historian of legal institutions. Two aspects are particularly investigated: 1 The thought of Leicht on relationship between Germanic legal traditions and Roman law; 2 His contributions on feudalism, Communes and guilds, which are significantly distant from those of Gioacchino Volpe.

    Full Text Available La discussione medievale sul tema dei futuri contingenti pone al centro dell’attenzione, da un lato, il modo di concepire conoscenza e potenza divine e, dall’altro, lo statuto degli eventi futuri. Pier Damiani, monaco dell’XI secolo, distingue fra la possibilità divina di mutare le conseguenze del passato e quella di produrre un passato interamente diverso. Pedro Damian, protagonista del racconto di Borges, riscatta il suo comportamento giovanile producendo poco alla volta un altro, diverso, passato.

    Full Text Available The scour phenomenon around bridge piers causes great quantities of damages annually all over the world. Collars are considered as one of the substantial methods for reducing the depth and volume of scour around bridge piers. In this study, the experimental and numerical methods are used to investigate two different shapes of collars, i.e, rectangular and circular, in terms of reducing scour around a single bridge pier. The experiments were conducted in hydraulic laboratory at university of Malaya. The scour around the bridge pier and collars was simulated numerically using a three-dimensional, CFD model namely SSIIM 2.0, to verify the application of the model. The results indicated that although, both types of collars provides a considerable decrease in the depth of the scour, the rectangular collar, decreases scour depth around the pier by 79 percent, and has better performance compared to the circular collar. Furthermore, it was observed that using collars under the stream's bed, resulted in the most reduction in the scour depth around the pier. The results also show the SSIIM 2.0 model could simulate the scour phenomenon around a single bridge pier and collars with sufficient accuracy. Using the experimental and numerical results, two new equations were developed to predict the scour depth around a bridge pier exposed to circular and rectangular collars.

    Full Text Available In this article, the authors study the decadence of wood piers along XIX century, mainly because of problems inherent to the attacks of invertebrates. Soon, the wood structures will be substituted by iron ones, appearing two extraordinary materials, cast iron and wrought iron. Cast iron was a material with a great compression resistance, but weak for traction and flexion. It was not welding, but its resistance to the corrosion was notable, because of it, was very used at piles of British sea piers. On the contrary, wrought iron offered high conditions for traction and flexion, so it appeared like a very useful material to make girders and joists, but suffering the problem of a lack of resistance to corrosion. The combination of both materials supposed a great success in the construction of bridges and piers, since 1850.

    Se estudia en el presente artículo cómo los embarcaderos de madera iban languideciendo a partir de mediados del siglo XIX, aquejados especialmente por los ataques de invertebrados. Pronto, en los embarcaderos británicos, la madera iba a ser sustituida por el hierro, en la versión de dos nuevos materiales, la fundición y el hierro forjado. La fundición poseía una gran resistencia a la compresión, aunque poca a la tracción y a la flexión. Tampoco permitía la soldabilidad, pero presentaba un comportamiento magnífico frente a la corrosión, siendo muy utilizada para pilares en los nuevos embarcaderos. El hierro forjado presentaba menor resistencia a la corrosión pero, en cambio, ofrecía altas prestaciones a tracción y flexión, lo que lo hacía muy valioso para su colocación en vigas y forjados en los muelles. De la combinación de ambos materiales resultó el gran éxito habido en la construcción de puentes y embarcaderos metálicos, a partir de 1850.

    Many design considerations must be addressed in order to provide researchers with full text and semantic search of unstructured healthcare data such as clinical notes and reports. Institutions looking at providing this functionality must also address the big data aspects of their unstructured corpora. Because these systems are complex and demand a non-trivial investment, there is an incentive to make the system capable of servicing future needs as well, further complicating the design. We present architectural best practices as lessons learned in the design and implementation NLP-PIER (Patient Information Extraction for Research), a scalable, extensible, and secure system for processing, indexing, and searching clinical notes at the University of Minnesota.

    Full Text Available Pier Luigi Nervi (1891-1979, poliedrico progettista, teorico, docente, costruttore e imprenditore, è stato senza dubbio uno dei protagonisti dell’architettura e dell’ingegneria del Novecento. Proprio l’essere riuscito a unire in sé le due figure – ormai da tempo distinte, nella formazione come nella professione – dell’ingegnere e dell’architetto, è stato uno dei fattori-chiave della sua opera, nella quale l’invenzione di nuove forme non è disgiunta dalla capacità di costruirle. Questo profilo interdisciplinare si è costruito negli anni della sua formazione nella Scuola di Applicazione per Ingegneri di Bologna, grazie agli insegnamenti ricevuti dai suoi maestri e alle esperienze di conoscenza e di pratica professionale, orientati a una “cultura politecnica”, alla coraggiosa volontà di sperimentazione e alla conoscenza della realtà tecnica e costruttiva.

    2008-01-01

    During cantilever cast in construction of high-pier and large-span continuous rigid frame bridges, structural stability in the longest cantilevered stage is very important. Based on a practical design case of a large-span continuous rigid frame bridge in Wuhan, the longest span stability coefficient is calculated with linear-buckling and nonlinear-buckling methods, respectively. The influences of both geometrical nonlinearity and the dual nonlinearity of material and geometry are considered. Numerical results indicate that the nonlinear solution is necessary to stability analysis because linear buckling loads axe much higher than those of nonlinear buckling. Thus, the edge fiber yield criterion is more convenient and faster than ultimate loading criterion when estimating nonlinear stability of structure, and can be used easily in the initial engineering design.

    Full Text Available Masonry structure is the main form of Chinese urban and rural housing construction structure. And heavy casualties and huge economic losses are caused by the damages of masonry structures in the previous destructive earthquake. So the failure modes of masonry structures are analyzed in the paper. ABAQUS software was used; and the Xuankou High School Student Dormitory of masonry structure in Yingxiu town, severely damaged under the Wenchuan earthquake, was taken for example. The influence of the stiffness ratio of pier between windows and spandrel on the failure modes of masonry structures is discussed. The results show that the failure modes in the earthquake could be changed by controlling the stiffness ratio. Suitable stiffness ratio helps proper design of masonry structures.

    The primary objectives of the computational fluid dynamics (CFD) analysis are (1) to verify that the design concept of using wedge shaped pier extensions to divert flow around piers as a scour counter measure has the intended effect on the flow, (2) to refine the design of the length and orientation of the pier extensions within the channel and (3) to optimize the guide walls that will protect a set of outer piers and the abutments on each side of the channel. The original proposed design is shown in Figure 1.3. The results of this effort are the recommended designs that are judged to be the best designs based on results from the set of test cases run combined with engineering judgment. The refined designs from the CFD analysis are expected to be tested in a limited set of physical model experiments to verify that they work well.

  13. Effect of nonlinearity of restrainer and supports on the elasto-plastic seismic response of continuous girder bridge

    2014-10-01

    Full Text Available During an earthquake, the nonlinearity of the bridge structure mainly occurs at the supports, bridge piers and restrainers. When entering nonlinear stage, members of the bridge structure affect the elasto-plastic seismic response of the whole structure to a certain extent; for multi-span continuous bridges, longitudinal restrainers can be installed on the movable piers to optimise the distribution of seismic force and enable the movable piers to bear a certain amount of seismic effect. In order to evaluate the effect of nonlinearity of restrainer and supports on the elasto-plastic seismic response of continuous girder bridge, analytical models of continuous girder bridge structure considering the nonlinearity of movable supports, restrainers and bridge piers were built and the nonlinear time history analysis was conducted to evaluate the effect of nonlinearity of restraining devices and supports on the elasto-plastic seismic response of continuous girder bridge. Relevant structural measures and recommendation were made to reduce the seismic response of the fixed piers of the continuous girder bridge.

    Benedict, Stephen T.; Caldwell, Andral W.

    2016-01-01

    The U.S. Geological Survey in cooperation with the South Carolina Department of Transportation collected clear-water pier- and contraction-scour data at 116 bridges in the Coastal Plain and Piedmont Physiographic Provinces of South Carolina. Pier-scour depths collected in both provinces ranged from 0 to 8.0 feet. Contraction-scour depths collected in the Coastal Plain ranged from 0 to 3.9 feet. Using hydraulic data estimated with a one-dimensional flow model, predicted clear-water scour depths were computed with scour equations from the Federal Highway Administration Hydraulic Engineering Circular 18 and compared with measured scour. This comparison indicated that predicted clear-water scour depths, in general, exceeded measured scour depths and at times were excessive. Predicted clear-water contraction scour, however, was underpredicted approximately 30 percent of the time by as much as 7.1 feet. The investigation focused on clear-water pier scour, comparing trends in the laboratory and field data. This comparison indicated that the range of dimensionless variables (relative depth, flow intensity, relative grain size) used in laboratory investigations of pier scour, were similar to the range for field data in South Carolina, further indicating that laboratory relations may have some applicability to field conditions in South Carolina. Variables determined to be important in developing pier scour in laboratory studies were investigated to understand their influence on the South Carolina field data, and many of these variables appeared to be insignificant under field conditions in South Carolina. The strongest explanatory variables were pier width and approach velocity. Envelope curves developed from the field data are useful tools for evaluating reasonable ranges of clear-water pier and contraction scour in South Carolina. A modified version of the Hydraulic Engineering Circular 18 pier-scour equation also was developed as a tool for evaluating clearwater pier

  16. Research on Motion Performance of the Mobile Double-Causeway Pier System

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Mobile offshore double-causeway pier system, a type of seashore unloading equipment, consists of two groups of multiple connected semi-submersible modules. This structure has wide application because most of the middle or mini type of vessels and ships can be moored to it. Based on the analysis of computational methods of multi-body motion response, a hydrodynamic model is set up and the three-dimensional potential theory in finite depth is adopted to calculate the three-dimensional motion response of this system. The double P-M spectrum is used to analyze the motion response in irregular waves. Different wave directions are specially taken into consideration, due to their various effects to the motion response. Furthermore, the calculated result is compared with that of the experiment, and it is proved that sway, heave, pitch and yaw motion are greatly constrained by mooring system. The comparison also indicates that the model can forecast the motion performance of the target, and that the calculated result can also be used as reference in connector and mooring system design.

    2013-01-01

    The Scour Rate In COhesive Soils-Erosion Function Apparatus (SRICOS-EFA) method includes an ultimate scour prediction that is the equilibrium maximum pier and contraction scour of cohesive soils over time. The purpose of this report is to present the results of testing the ultimate pier and contraction scour methods for cohesive soils on 30 bridge sites in Illinois. Comparison of the ultimate cohesive and noncohesive methods, along with the Illinois Department of Transportation (IDOT) cohesive soil reduction-factor method and measured scour are presented. Also, results of the comparison of historic IDOT laboratory and field values of unconfined compressive strength of soils (Qu) are presented. The unconfined compressive strength is used in both ultimate cohesive and reduction-factor methods, and knowing how the values from field methods compare to the laboratory methods is critical to the informed application of the methods. On average, the non-cohesive method results predict the highest amount of scour, followed by the reduction-factor method results; and the ultimate cohesive method results predict the lowest amount of scour. The 100-year scour predicted for the ultimate cohesive, noncohesive, and reduction-factor methods for each bridge site and soil are always larger than observed scour in this study, except 12% of predicted values that are all within 0.4 ft of the observed scour. The ultimate cohesive scour prediction is smaller than the non-cohesive scour prediction method for 78% of bridge sites and soils. Seventy-six percent of the ultimate cohesive predictions show a 45% or greater reduction from the non-cohesive predictions that are over 10 ft. Comparing the ultimate cohesive and reduction-factor 100-year scour predictions methods for each bridge site and soil, the scour predicted by the ultimate cohesive scour prediction method is less than the reduction-factor 100-year scour prediction method for 51% of bridge sites and soils.

    Dhakal, Dinesh

    Bridges are the long term investment of the highway agencies. To maintain the required service level throughout the life of a bridge, a series of maintenance, repair, and rehabilitation (MRℝ) works can be performed. To investigate the corrosion deterioration and maintenance and repair practices in the bridge pier columns constructed in chloride-laden environment, a questionnaire survey was conducted within the 50 state Departments of Transportation (DOTs). Based on the survey data, two corrosion deterioration phases were identified. They were corrosion crack initiation phase and corrosion propagation phase. The data showed that the mean corrosion crack initiation phase for bridge pier column having cover of 50 mm, 75 mm, and 100 mm was 18.9 years, 20.3 years, and 22.5 years, respectively. The corrosion propagation phase starts after the corrosion crack initiation. The corrosion propagation is defined in a single term, corrosion damage rate, measured as percentage of area damaged due to corrosion cracking, spalling, and delamination. From the survey, the corrosion damage rate was found 2.23% and 2.10% in the bridge pier columns exposed to deicing salt water and exposed to tidal splash/spray, respectively. For this study, two different corrosion damage rates were proposed before and after the repair criteria for minor damage repair as practiced by DOTs. This study also presents the collected data regarding the corrosion effectiveness of using sealers and coatings, cathodic protection, corrosion inhibitors, carbon fiber/epoxy composites, and glass fiber/epoxy composites as maintenance and repair technique. In this study, the cost-effectiveness of wrapping carbon fiber/epoxy composites and glass fiber/epoxy composites in bridge pier columns constructed in a chloride-laden environment was investigated by conducting life-cycle cost analysis. As a repair work, externally bonded two layer of carbon fiber/epoxy and glass fiber/epoxy composites were installed by wet

    The concentration of various metals in the fruit harvested from Lowbush blueberry plants in Whitney Pier, Sydney, Nova Scotia (NS), North Sydney (NS) and supermarket were quantified in this report. The concentrations were compared among the 3 sources to determine whether the metal and Polycyclic Aromatic Hydrocarbons (PAHs) concentrations in the blueberries from Whitney Pier were higher or lower compared to the reference blueberries from North Sydney and the supermarket. Mean values for each of the analytes were compared using analysis of variance (ANOVA). The study determined whether washed berries have lower concentrations of contaminants than unwashed berries. The risk to human health of exposure to metals and PAHs through consumption of blueberry samples was also calculated. It was concluded that concentrations of selenium and zinc are elevated in blueberries from Whitney Pier compared to berries from North Sydney and the supermarket, but are well within safe levels. Other elements such as arsenic, titanium, vanadium, lead, copper and molybdenum were similar, and only thallium was elevated in supermarket berries relative to those from Whitney Pier and North Sydney. Chromium was not detected in any samples. It was determined that there was no risk to human health from exposure to any of the metals analyzed, regardless of whether they were Whitney Pier samples or reference samples. Only 2 PAHs were detected in one of the unwashed samples from Whitney Pier. No PAHs were found in washed berries or unwashed berries from the supermarket or North Sydney. It was concluded that there was no risk to human health from exposure to any of the PAHs. Washed and unwashed samples had similar metal concentrations, indicating that surface contamination did not occur. A full methodology of the testing program was provided. 11 refs., 7 tabs., 2 figs.

  1. Analytical Evaluation of Reinforced Concrete Pier and Cast-in-Steel-Shell Pile Connection Behavior considering Steel-Concrete Interface

    2016-01-01

    Full Text Available The seismic design of bridges may require a large-diameter deep pile foundation such as a cast-in-steel-shell (CISS pile where a reinforced concrete (RC member is cast in a steel casing. In practice, the steel casing is not considered in the structural design and the pile is assumed to be an RC member. It is partially attributed to the difficulties in evaluation of composite action of a CISS pile. However, by considering benefits provided by composite action of the infilled concrete and the steel casing, both the cost and size of CISS pile can be reduced. In this study, the structural behavior of the RC pier and the CISS pile connection is simulated by using an advanced 3D finite element (FE method, where the interface between the steel and concrete is also modeled. Firstly, the FE model is verified. Then, the parametric study is conducted. The analysis results suggest that the embedment length and the friction coefficient between the steel casing and the infilled concrete affect the structural behavior of the RC pier. Finally, the minimum embedment length with reference to the AASHTO design guideline is suggested considering the composite action of the CISS pile.

  2. Influence of piers on functional groups of benthic primary producers and consumers in the channel of a subtropical coastal lagoon

    2012-03-01

    Full Text Available Artificial habitats have become common in coastal areas worldwide and may influence the structure and functioning of benthic ecosystems. We analyze the influence of piers on the benthic morphofunctional groups of rocky seaweeds and of soft bottom macrofauna in the channel of Conceição Lagoon (southern Brazil. The main impact is a reduction in the luminosity available for photosynthetic activity which is directly related to a decrease in the biomasses of sediment microphytobenthos and of more highly structured macroalgae life-forms. Contrary to expectations, the morphotypes of potentially high biomass productivity, such as articulated coralline, corticated and leathery macroalgae, were in general less abundant and the low biomass foliose and filamentous macroalgae occurred in reference areas but not under the piers. The piers' effects on motile epifauna and infauna functional groups were site-specific and probably related to the general reduction in primary producer organisms in the new habitats. The discretely motile infauna was the only functional group able to thrive under the piers due to their reduced motility and fragile morphological structures, being benefited by the shelter provided by the artificial habitats. Our results showed that the piers might have a negative effect on the base-trophic level organisms responsible for bottom-up controls.Hábitats artificiais têm se tornado comum em áreas costeiras no mundo todo, podendo influenciar a estrutura e funcionamento de ecossistemas bênticos. Nós analisamos a influência de trapiches nos grupos morfofuncionais bênticos de algas associadas a substrato consolidado e de macrofauna em substrato inconsolidado, no canal da Lagoa da Conceição (sul do Brasil. O principal impacto da presença de trapiches é a redução da irradiação disponível para atividade fotossintética, o que está diretamente relacionado com o decréscimo na biomassa microfitobentônica no sedimento e de macroalga

    Bridges are usually lifeline engineering-in-traffic projects,and their seismic performance is very important.As an important bridge construction component,piers are vulnerable to dam-age under strong ground motion.In this paper,in accord with the typical pier structure form of bridge piers in mountainous areas,a nonlinear numerical analysis model is constructed based on a fiber model.The seismic response of different piers under El-Centro is performed using modal pushover analysis (MPA).By comparison with the nonlinear time history analysis method,the applicability of the MPA method for the seismic analysis of different piers is investigated.The results show that the MPA method is not suitable for higher piers where the contribution of higher modes in seismic response is significant.With the implementation of the Western Develop-ment Program in recent years,a lot of highways and railways have been planned and built in western China.For bridges with high piers in mountainous areas,a nonlinear numerical analysis model is constructed based on a fiber model.The finite-element analysis is simulated with the code Open Sees,which was developed by Pacific Earthquake Engineering Research (PEER).The Mander model is used to imitate the constitutive model of concrete,and the Giuffré-Menegotto-Pinto model is used to imitate the constitutive model of reinforcement.The incremental dynamic analysis is used to research distribution features of pier section curvature under strong earthquake motions.As a result of the effects of higher modal contributions,the seismic response and seis-mic performance of bridges with high piers are complicated.The forming and development of a plastic range in the upper position of a pier,the damage process,and the failure mechanism of high piers under different earthquake motions are studied.The base section curvature of high piers and its top displacement are not simultaneous;it is inappropriate for pier top displacement to be used as the

    Since the beginning of the 1 990s,performance-based seismic design theory has entered the mainstream of structural seismic research.The purpose of performance-based seismic design theory is to determine the seismic performance objectives of a building based on its use,impor-tance,and level of seismic fortification.Buildings designed in accordance with those objectives will safely withstand earthquakes that may occur in the future.On the bridge,plastic hinges placed on the piers were used to consume earthquake energy.Design for ductility can avoid collapse of the bridge.However,permanent deformation of the plastic hinges could cause serious damage to the pier.It is difficult to immediately repair bridges following earthquakes.Many transportation func-tions are significantly slowed or lost.In order to ensure that the transportation capacity of bridges is recovered quickly after a strong earthquake,many structural systems have been proposed,inclu-ding rocking bridge piers and self-centering bridge piers.The continuous rigid frame bridge system with displacement-restricted piers was consistent with the concept of rocking piers.This structure can realize three important functions:(1 )limit the maximum displacement of pier,(2 )prevent the bridge from overturning,and (3 )adjust the coefficient of friction at the pier bottom.By adhering to these objectives between the pier bottom and the pier cap,the displacement-restricted earthquake mitigation. This study concluded that the continuous rigid frame bridge system with displacement-restricted piers could reduce ductility and strength demands on the bridge piers.This paper compared the displacement limits of 2 cm,5 cm,8 cm and traditional piers.The results showed that the displacement of the pier top,the bending moment at the pier bottom,and the bending moment of the pier at the bridge beam with the displacement-restricted 2 cm,5 cm,8 cm piers were much less than the piers of a traditional continuous rigid frame bridge

    By utilizing the current finite element program ANSYS, two types of finite element models (FEM), the beam model (BM) and shell model (SM), are established for the nonlinear stability analysis of a practical rigid frame bridge-Longtanhe Great Bridge. In these analyses, geometrical and material nonlinearities are simultaneously taken into account. For geometrical nonlinearity, updated Lagrangian formulations are adopted to derive the tangent stiffness matrix. In order to simulate the nonlinear behavior of the plastic hinge of the piers, the multi-lines spring element COMBIN39 is used in the SM while the bilinear rotational spring element COMBIN40 is employed in the BM. Numerical calculations show that satisfying results can be obtained in the stability analysis of the bridge when the double coupling nonlinearity effects are considered. In addition, the conclusion is significant for practical engineering.

The results show that appropriate stiffness ratio of columns and shear links is needed, and the distance between columns satisfies the requirement of the shear yield of shear links, and the influence of the layout fashion of shear links is ignored.

    Pre-eclampsia is one of the leading causes of maternal death and morbidity in low-resource countries due to delays in case identification and a shortage of health workers trained to manage the disorder. Pre-eclampsia Integrated Estimate of RiSk (PIERS) on the Move (PotM) is a low cost, easy-to-use, mobile health (mHealth) platform that has been created to aid health workers in making decisions around the management of hypertensive pregnant women. PotM combines two previously successful innovations into a mHealth app: the miniPIERS risk assessment model and the Phone Oximeter. The aim of this study was to assess the usability of PotM (with mid-level health workers) for iteratively refining the system. Development of the PotM user interface involved usability testing with target end-users in South Africa. Users were asked to complete clinical scenario tasks, speaking aloud to give feedback on the interface and then complete a questionnaire. The tool was then evaluated in a pilot clinical evaluation in Tygerberg Hospital, Cape Town. After ethical approval and informed consent, 37 nurses and midwives evaluated the tool. During Study 1, major issues in the functionality of the touch-screen keyboard and date scroll wheels were identified (total errors n=212); during Study 2 major improvements in navigation of the app were suggested (total errors n=144). Overall, users felt the app was usable using the Computer Systems Usability Questionnaire; median (range) values for Study 1 = 2 (1-6) and Study 2 = 1 (1-7). To demonstrate feasibility, PotM was used by one research nurse for the pilot clinical study. In total, more than 500 evaluations were performed on more than 200 patients. The median (interquartile range) time to complete an evaluation was 4 min 55 sec (3 min 25 sec to 6 min 56 sec). By including target end-users in the design and evaluation of PotM, we have developed an app that can be easily integrated into health care settings in low- and middle-income countries

    A new-style flood discharging dam, which consolidates the flaring gate pier and the stepped spillway for discharging the flood through the dam surface, had been applied in China. The theoretical study on it is in a beginning stage at present. The three-dimensional numerical simulation has not been reported. In this paper, the 3D numerical calculation on the two-phase flow of water and air with discharge per unit width 195m3/s* m is presented . The results indicate that there is negative pressure on the juncture of the spillway surface and the first step. There forms obvious longitudinal and transverse eddies on the steps and the velocity decreases obviously compared with the smooth spillway. The figures of the velocity distributions and the water-air two-phase flows are plotted. The results calculated on the pressure are in agreement with the experimental data. Based on the position of the negative pressure obtained from calculation, measurement points of pressure are arranged in physical model. The experimental results validate the existence of the negative pressure. Being an applied and trial study, the results obtained are of theoretical and practical significance.

    An ambitious project connecting Jammu and Srinagar through a railway link in tectonically active and geologically complex Himalayan Mountain terrain is under progress. Under this project, the world's highest (359 m) railway arch-bridge is under construction across the River Chenab in the northern territory of India. This mega engineering structure has a two-fold ribbed arch design, comprising of steel girders. During the excavation for one of the concrete pillars on the right abutment, wide open joints and weak/shear zones were noticed. The width of these joints varies from 30 to 50 cm, trending along N170° with a dip of 65°. The foundation area of this pillar is 13 m × 24 m and on the cut slopes of the right bank of Chenab River. These exposed joints and weak zones were treated with consolidation grouting to strengthen the foundation area. To delineate the extent of these joints and weak zones below the foundation level, seismic tomography was carried out in five boreholes drilled for this purpose to cover the 300 sq-m area. The results of cross-hole seismic tomography reveals the presence of three low velocity (≤ 2600 m/s) anomalous zones below the foundation area. This also ascertained the efficacy of grouting in consolidating the joints and weak zones. Later, rock-mass quality (Q) was determined based on the relationship between the P-wave velocity and the Q-value (Barton, 2002) to infer the support system for the slope stabilization below the foundation. 3-D visualization of the seismic velocity demarcates the extent of weak or untreated zones. This methodology facilitates to update the design parameters according to Q-values during the construction stage and estimate the required level of reinforcement and support system. Similar methodology can be applicable in other areas under same site conditions.

    This report is a supplement to a previous report [ref] covering optimization of wedge shaped pier extensions to streamline large bluff body piers as a local scour countermeasure for the Burlington Northern and Santa Fe (BNSF) Railroad Bridge over the Santa Ana River downstream of Prado Dam in Riverside County, CA. The optimized design was tested in a 1/30 scale physical model at U.S. Army Engineer Research and Development Center (ERDC) in Vicksburg, MS, and the optimized design was used as the base for the construction design. Constructability issues having to do with both materials and site conditions including access underneath the BNSF bridge yielded a construction design that required making the pier extensions wider and either moving the western curve of the west guide wall upstream or changing its geometry.

    Full Text Available Il presente lavoro si muove in direzione di una narratologia intertestuale che integri una riflessione semiotica e strumenti di logica, ponendo al centro il concetto di «configurazione» quale modello di comprensione (Mink, Ricoeur. Il concetto di «sceneggiature intertestuali» permette di accostarsi all‘atto di lettura interpretandolo come procedimento di abduzione, attraverso cui il Lettore Modello (Eco trova nella propria enciclopedia intertestuale le cosiddette «sceneggiature» ossia «strutture di base» più o meno riconoscibili in ogni racconto. Tramite una lettura di Lolita si giunge a delineare l‘atto interpretativo come un procedimento abduttivo in cui ricorrono «sceneggiature intertestuali», potendo così individuare nel testo quei percorsi, spesso latenti, che una lettura critica deve essere capace non solo di seguire ma anche di tracciare.

  8. Pounding Effects in Simply Supported Bridges Accounting for Spatial Variability of Ground Motion: A Case Study

    2012-01-01

    Full Text Available This study carries out a parametrical analysis of the seismic response to asynchronous earthquake ground motion of a long multispan rc bridge, the Fener bridge, located on a high seismicity area in the north-east of Italy. A parametrical analysis has been performed investigating the influence of the seismic input correlation level on the structural response: a series of nonlinear time history analyses have been executed, in which the variation of the frequency content in the accelerograms at the pier bases has been described by considering the power spectral density function (PSD and the coherency function (CF. In order to include the effects due to the main nonlinear behaviours of the bridge components, a 3D finite element model has been developed, in which the pounding of decks at cap-beams, the friction of beams at bearings, and the hysteretic behaviour of piers have been accounted for. The sensitivity analysis has shown that the asynchronism of ground motion greatly influences pounding forces and deck-pier differential displacements, and these effects have to be accurately taken into account for the design and the vulnerability assessment of long multispan simply supported bridges.

    At present, there is less aseismic research on the upper auxiliary structure and has no standards for mention, so it leads to random and empirical knowledge for equivalent static calculation. Dynamic time-history method is applied to calculate pier and frame structures of a hydropower station in the northwestern districts by using ADINA software. And the coupling effect between different structures is discussed under the action of earthquake through dynamic characteristics of different structures and response characteristics at different operating conditions. The results show that under the action of earthquake, pier and frame structures with mutational mass and stiffness in vertical direction produce structural damages like whiplash effect easily. So this phenomenon must be taken a special attention when designing.%鉴于我国对上部附属结构抗震研究较少,规范中也未专门提及,由此导致设计人员进行等效静力计算时带有一定的随意性和经验性.借助有限元软件ADINA,利用动力时程分析法计算了西北地区某水电站的闸墩和框架结构,并通过各结构的动力特性和不同工况下的响应特点,探讨了地震作用下结构之间的耦联作用.结果表明,在地震作用时,质量和刚度沿竖向均存在明显突变的高闸墩和框架结构易产生类鞭梢效应的结构破坏,设计时应引起格外重视.

    The main bridge of Wuhan Erqi Changjiang River Bridge is a three-pylon composite girder cable-stayed bridge. The pile cap of pylon pier No. 3 of the bridge is located in deepwater and was constructed in dry environment in large steel boxed cofferdam. To resolve the problem of accurate positioning of the large cofferdam, the pulling and berthing pier system was used after comparison of the different positioning schemes. The pier system is composed of a pulling pier at the upstream side and a berthing pier at the downstream side, on the pulling pier, the main pulling cables and tie-down cables were set while on thg berthing pier, the crisscross pulling cables were set. The positioning anchors were cast into the river longitudinally along the bridge and the side anchoring cables were set. After construction preparation, the cofferdam was initially posi-tioned by the pulling and berthing pier system to make the cofferdam basically set in place in plan position. By using the side anchoring cables, pulling cables and by means of non-uniform pumping of water into the bulks of the cofferdam, the plan position, plan torsion, oscillation and perpendicularity of the cofferdam were adjusted and the plan offsetting of the cofferdam was brought to be within +12 mm, the torsional angle to be 58" and the inclination to be 1/3 000 so as to make the construction of the cofferdam meet the relevant requirements in the codes and eventually realize the accurate positioning of the cofferdam.%武汉二七长江大桥主桥为三塔结合梁斜拉桥,其3号墩位于深水中,采用钢吊箱实现承台干施工.为解决大型钢吊箱精确定位难题,经过方案比选,采用拉靠墩系统定位方案,该系统由上游拉墩和下游靠墩组成,拉墩设主拉缆和下拉缆,靠墩设交叉拉缆,顺桥向抛锚,设置边锚缆.施工准备后,利用拉靠墩系统进行钢吊箱初定位,使其平面位置基本就位;通过边锚缆系统、拉缆系统及夹壁舱不均衡灌

    Full Text Available To speak of St. Peter Damian's poetry is not easy, there are many literary genres, different contexts, among which the liturgy stands out, but there are also lyrics related to monastic life, and to the controversial ills' corrections of the Church of his time, such as simony and nicolaism. The complete edition published in 2007, that is the result of a long process of critical and theological research, wants to be a new way of approaching the poetry of the saint, trying to underline the sources, the occasion for the composition and finally to provide an additional seat contribution to approach ever more fully to his great personality.

    Parlare della poetica di san Pier Damiani non è facile, tanti i generi letterari, diversi i contesti fra i quali primeggia quello liturgico, ma anche poesie in versi legate alla vita monastica, alla correzione polemica dei mali della Chiesa del suo tempo, come la simonia e il nicolaismo. L'edizione integrale apparsa nel 2007, frutto di un lungo percorso di ricerca critica e teologica, vuole essere un modo nuovo di accostare la produzione poetica del santo cercando di evidenziare le fonti, l'occasione per la composizione e in ultima sede fornire un ulteriore contributo per accostarne sempre più pienamente la grande personalità.

    Preeclampsia is a leading cause of maternal morbidity. The clinical challenge lies in predicting which women with preeclampsia will suffer adverse outcomes and would benefit from treatment, while minimizing potentially harmful interventions. Our aim was to determine the ability of maternal symptoms (i.e., severe nausea or vomiting, headache, visual disturbance, right upper quadrant pain or epigastric pain, abdominal pain or vaginal bleeding, and chest pain or dyspnea) to predict adverse maternal or perinatal outcomes. We used data from the PIERS (Pre-eclampsia Integrated Estimate of RiSk) study, a multicentre, prospective cohort study designed to investigate the maternal risks associated with preeclampsia. Relative risks and receiver operating characteristic (ROC) curves were assessed for each preeclampsia symptom and outcome pair. Of 2023 women who underwent assessment, 52% experienced at least one preeclampsia symptom, with 5.2% and 5.3% respectively experiencing an adverse maternal or perinatal outcome. No symptom and outcome pair, in either of the maternal or perinatal groups, achieved an area under the ROC curve value > 0.7, which would be necessary to demonstrate a discriminatory predictive value. Maternal symptoms of preeclampsia are not independently valid predictors of maternal adverse outcome. Caution should be used when making clinical decisions on the basis of symptoms alone in the preeclamptic patient.

    Using molecular techniques, a longitudinal study was conducted with the aims at identifying the seasonal difference of Cryptosporidium contamination in surface water as well as analyzing the potential sources based on species information. One hundred forty-four water samples were collected, 72 samples from the Chao Phraya River, Thailand, collected in the summer, rainy and cool seasons and 72 samples from sea water at Bang Pu Nature Reserve pier, collected before, during and after the presence of migratory seagulls. Total prevalence of Cryptosporidium contamination in river and sea water locations was 11% and 6%, respectively. The highest prevalence was observed at the end of rainy season continuing into the cool season in river water (29%) and in sea water (12%). During the rainy season, prevalence of Cryptosporidium was 4% in river and sea water samples, but none in summer season. All positive samples from the river was C. parvum, while C. meleagridis (1), and C. serpentis (1) were obtained from sea water. To the best of our knowledge, this is the first genetic study in Thailand of Cryptosporidium spp contamination in river and sea water locations and the first report of C. serpentis, suggesting that humans, household pets, farm animals, wildlife and migratory birds may be the potential sources of the parasites. The findings are of use for implementing preventive measures to reduce the transmission of cryptosporidiosis to both humans and animals.

    Full Text Available Pre-eclampsia/eclampsia are leading causes of maternal mortality and morbidity, particularly in low- and middle- income countries (LMICs. We developed the miniPIERS risk prediction model to provide a simple, evidence-based tool to identify pregnant women in LMICs at increased risk of death or major hypertensive-related complications.From 1 July 2008 to 31 March 2012, in five LMICs, data were collected prospectively on 2,081 women with any hypertensive disorder of pregnancy admitted to a participating centre. Candidate predictors collected within 24 hours of admission were entered into a step-wise backward elimination logistic regression model to predict a composite adverse maternal outcome within 48 hours of admission. Model internal validation was accomplished by bootstrapping and external validation was completed using data from 1,300 women in the Pre-eclampsia Integrated Estimate of RiSk (fullPIERS dataset. Predictive performance was assessed for calibration, discrimination, and stratification capacity. The final miniPIERS model included: parity (nulliparous versus multiparous; gestational age on admission; headache/visual disturbances; chest pain/dyspnoea; vaginal bleeding with abdominal pain; systolic blood pressure; and dipstick proteinuria. The miniPIERS model was well-calibrated and had an area under the receiver operating characteristic curve (AUC ROC of 0.768 (95% CI 0.735-0.801 with an average optimism of 0.037. External validation AUC ROC was 0.713 (95% CI 0.658-0.768. A predicted probability ≥25% to define a positive test classified women with 85.5% accuracy. Limitations of this study include the composite outcome and the broad inclusion criteria of any hypertensive disorder of pregnancy. This broad approach was used to optimize model generalizability.The miniPIERS model shows reasonable ability to identify women at increased risk of adverse maternal outcomes associated with the hypertensive disorders of pregnancy.

    应用CFD软件对船舶通过桥区时的船体-桥墩水动力相互作用进行数值研究,通过使用动网格技术及UDF进行船舶运动过程中的网格更新,对船舶沿直线航线匀速驶经桥墩时的非定常粘性流场进行数值模拟,对桥墩诱导的船体非定常水动力进行数值预报,其中假设船舶航速很小,因而自由面兴波的影响可以忽略.以一艘集装箱船和一个垂直柱体桥墩模型为例,选取不同的船体-桥墩横向距离进行了数值计算,得到了作用在船体上的横向力和转首力矩时历曲线,分析了船体-桥墩横向距离对船体非定常水动力的影响.%A general-purpose CFD software is applied to study the hydrodynamic interaction between a bridge pier and a ship passing through the bridge area along a straight course at constant speed. By using the dynamic mesh technique and UDF to update the mesh, the unsteady viscous flow around the ship is numerically simulated and the unsteady hydrodynamic force on the hull induced by the pier is predicted. The ship speed is assumed to be small, so that the effect of free surface elevation is negligible. Numerical calculations are performed for a container ship and a vertical column as a simplified pier model at various distances between the ship and the pier. The time histories of the lateral force and yaw moment are obtained. The influence of the distance between the ship and the pier is analyzed.

    2010-12-01

    Full Text Available This work presents and evaluates the performance of a simulation model based on multiagent system technology in order to support logistic decisions in a harbor from oil supply chain. The main decisions are concerned to pier allocation, oil discharge, storage tanks management and refinery supply by a pipeline. The real elements as ships, piers, pipelines, and refineries are modeled as agents, and they negotiate by auctions to move oil in this system. The simulation results are compared with results obtained with an optimization mathematical model based on mixed integer linear programming (MILP. Both models are able to find optimal solutions or close to the optimal solution depending on the problem size. In problems with several elements, the multiagent model can find solutions in seconds, while the MILP model presents very high computational time to find the optimal solution. In some situations, the MILP model results in out of memory error. Test scenarios demonstrate the usefulness of the multiagent based simulator in supporting decision taken concerning the logistic in harbors.

    To investigate the seismic performance of reinforced concrete (RC) rectangular hollow bridge piers, cyclic testing on five well-confined specimens was performed under constant axial load and biaxial bending. The test variables included axial load ratio, longitudinal reinforcement ratio and lateral reinforcement ratio. The results show that these specimens are flexural failure modes; biaxial force and displacement hysteretic loops show significant stiffness and strength degradation, pinching effect and coupling interaction of the structural seismic resistances in both directions; the ductility coefficient, varying from 3. 5 to 5. 7, and the equivalent viscous damping ratio, varying from 0. 19 to 0. 26, can meet the requirements of seismic design; RC rectangular hollow bridge piers with configurations of lateral reinforcement subject to bi-directional earthquake components have excellent earthquake resistance, and can substitute for current hollow RC rectangular section configurations described in the Chinese Guideline for Seismic Design of Highway Bridges (JTG/T B02-01-2008); and the length of the plastic hinge region is found to approach one sixth of the the hollow RC rectangular bridge pier height for all specimen piers, which is far less than the currently specified minimum value in Chinese Guideline, so the length of plastic hinge region is more concentrated for RC rectangular hollow bridge piers.%为了研究水平双向地震作用下矩形空心桥墩的抗震性能,对约束良好但轴压比和纵向、横向配筋率不同的5个钢筋混凝土(RC)矩形空心桥墩在轴力和双向弯曲作用下的性能进行了循环试验研究.结果表明:试件破坏形态为桥墩底部形成塑性铰的弯曲形破坏,桥墩双向力-位移滞回曲线显示了双向压弯状态下RC矩形空心桥墩刚度和强度退化、捏拢效应以及2个水平方向抗震性能的相互影响;试件桥墩的延性系数在3.5~5.7之间,等效粘滞阻尼系数在0

    Hollow section piers are often used in reinforced concrete(RC)bridges. It has been proved by earthquake damage investigation that the piers may perform flexure-shear coupling behavior,and eventually lead to pier failure and/or collapse. A fiber-section based RC pier simulation model considering flexure-shear coupling effect was pre-sented in this paper. By introducing bi-axial material constitutive relationship into the determination of fiber deforma-tion status,the sectional stiffness for beam column element can be obtained through the integration of fiber responses. Then the flexure-shear coupling Timoshenko beam element was implemented. The cyclic soften membrane model(CSMM)constitutive relationship was adopted for plane bi-axial RC components in the calculation of the nonlinear characteristic of fibers. The concrete uniaxial material model in CSMM was improved. By assuming the compatibility condition between each fiber and making use of the Newton iteration algorithm,the fiber and section responses were determined. At last,a scaled hollow section pier with quasi-static test result was compared with the numerical model,and the results show good agreement. The strength and stiffness degradation and pinching effect caused by flexure-shear coupling effect are captured by this model. And the fiber model shows sufficient accuracy and computational efficiency.%钢筋混凝土(RC)桥墩构件常采用空心截面,震害调查表明其失效模式多表现为弯剪耦联的非线性破坏。本文提出一种基于纤维截面、考虑弯剪耦联变形的混凝土墩柱模拟模型。首先将双轴材料本构引入纤维材料状态的计算,然后通过纤维截面积分,得到适用于 Timoshenko 梁柱单元的截面刚度矩阵,最终实现考虑弯剪耦联效应的梁柱单元。其中,双轴 RC 本构模型采用往复软化薄膜模型(CSMM),并对 CSMM 中单轴混凝土滞回模型进行修正。通过引入纤维

    Quasi-static tests on two half-scale two-story brick-concrete sub-structure models were carried out in order to improve the seismic performance of brick-concrete masonry school buildings. The wall piers between openings were partially reinforced with horizontal reinforcements that were reliably anchored using vertical reinforcements. The failure modes, load bearing capacity, deformability, rigidity degradation, ductility and hysteretic behavior of the two models, as well as failure modes of piers and failure mechanism of longitudinal walls were investigated. The results indicate that a story mechanism occurs in ordinary masonry model with the piers failing in shear failure. And the longitudinal walls exhibit strong spandrel-weak pier failure mechanism. However, partially reinforced wall piers are characterized by flexural failure with horizontal cracking in the mortar bed joints. Spandrels are severely damaged due to the formation of global failure mechanism. Strong pier-weak spandrel failure mechanism is guaranteed with uniform drift distribution. The level of damage, energy dissipation capacity and ductility of model are significantly improved.%为改善砖混结构教学楼的抗震性能,通过对其纵向窗间墙局部配筋并在墙体两端采用竖向钢筋进行锚固配筋,按照1/2的缩尺比例设计了2个砖混子结构模型.采用拟静力试验分别对普通窗间墙和配筋窗间墙的子结构模型的破坏模式、承载能力、变形能力、刚度退化、延性、耗能性能以及窗间墙的破坏模式和纵墙的破坏机制等进行了分析.结果表明:普通窗间墙模型表现为层间破坏机制,窗间墙发生剪切破坏,纵墙发生“强梁弱柱”式破坏;窗间墙局部配筋并进行锚固的模型发生整体型破坏,窗间墙弯曲破坏,纵墙的破坏机制具有“强柱弱梁”特征,层间变形均匀,模型的破坏形态、耗能能力和延性等均得到改善.

    Research purposes: The highway in western China or the remote region needs to cross over rivers and valleys and passes the regions with complex terrains due to the limitation of topographical condition . For this reason, the long -span continuous rigid frame bridge with high pier becomes more and more and the height of the bridge increases from several decameters to hundreds of meters. With increases of the pier height and the span length, the research on the stability of such kind of bridge is becoming more and more important. Research conclusions:Taking the long - span continuous rigid frame bridge with(90 + 168+90) m high pier in Shanxi province as the engineering background, the basic principle related to the structure stability is discussed and the stability of the high pier, the stability of the longest cantilever during construction and the stability in complete stage of the bridge are analyzed. From the calculation results it can be seen that for the bridge presented in this paper, the temperature effect has a little influence on the high pier stability, the wind load along the bridge axial direction has the most negative impact on the structure stability in the construction stage of the longest cantilever, and during the complete stage of the bridge, the lane load and the load of the crowded people set on the middle span has the most negative impact on the bridge stability. Furthermore, wind has a little influence and the influence of the temperature effect can be ignored in this stage. The calculation results also show this bridge has a good stability during its construction process and in the complete stage of bridge. The calculation and analysis processes presented in this paper can provide the reference to the similar works.%研究目的:西部地区及偏远地区受地形条件的限制,修建公路时常需要跨越河流、沟谷等复杂地形,因此高墩大跨连续刚沟桥的修建日益增多,其墩高也由原来的几十米提

To make sure that the caisson could be accurately landed onto the riverbed, the spatial model for the caisson and its tie anchor rope system was set up by the finite element software MIDAS 2006, the process of the landing of the caisson was simulated, the changing laws of the caisson offsetting and anchor rope forces in the process of the landing were analyzed and it was determined that the distance between the bottom of the caisson and the riverbed should be kept 2 m at the time the caisson was being positioned. To minimize the influences of the scouring, soil non-uniformity of the riverbed, waves and vortex vibration on the accurate landing of the caisson onto the riverbed, the measures of pumping water into the caisson for quick landing of the caisson, rectifying the offsetting of the caisson by winching the anchors, increasing the numbers and rigidity of the side anchors of the caisson and increasing the mass and damping of the caisson itself were respectively taken.%合福铁路铜陵长江大桥主桥为主跨630 m的三索面钢桁梁斜拉桥,其北桥塔3号墩采用圆端形沉井基础,沉井着床采用“二次定位、注水快速着床”的方案.为使沉井精确着床,采用MIDAS 2006有限元软件建立沉井和拉缆系统空间模型,模拟沉井着床过程,分析沉井着床过程中的偏移及拉缆索力变化规律,确定定位时沉井底与河床的距离为2 m.为减小冲刷、河床平面土质分布不均、波浪和涡激振动等对沉井精确着床的影响,分别采取了注水快速着床、绞锚纠偏回位、增加沉井边

    Quasi-static tests were conducted to study the seismic flexural-shear damage mechanisms and rapid repair techniques for earthquake damaged bridge piers.Six original pier specimens of circular cross sections were severely damaged under cyclic lateral force and constant axial load,and the damaged specimens were subsequently repaired using high-fluidity concrete with high early-strength and Carbon Fiber-Reinforced Polymer(CFRP),and then put into test again within a week.The failure pattern,strength,ductility and dissipated energy parameters and stiffness degradation of the repaired specimens were compared with the original ones.It is founded that the ultimate performance of bridge piers designed according to current seismic design codes of JTG/T B02-01—2008 and Caltrans with minimum confining reinforcement ratios may be dominated by shear failure in the plastic hinge zones.The repaired specimens show lower initial stiffness and larger yield displacement as a result of the pre-existing damage.But the failure for all of the repaired specimens was due to flexure,with higher strength,larger or the same ductility and dissipated energy parameters and recovered stiffness,which demonstrated the effectiveness of the proposed repair techniques.%为研究钢筋混凝土桥墩的地震弯剪破坏机理与震后快速修复技术,首先进行了6个圆形截面桥墩试件的拟静力试验,试件均发生严重弯剪破坏,然后利用高流动性早强混凝土和CFRP布对其进行快速修复并在1周内重新进行加载试验,将原桥墩与修复后试件的破坏形态、承载力、延性与耗能能力、刚度退化等进行了对比分析。研究表明:塑性铰区配箍满足我国《公路桥梁抗震设计细则》(JTG/T B02-01—2008)及美国Caltrans规范要求的钢筋混凝土桥墩试件,最终仍有可能因塑性铰区抗剪强度不足发生弯剪破坏。由于初始损伤的存在,震后修复

    Two articles in the current issue of the Psychiatric Rehabilitation Journal bring into focus the important question of the importance of work, and in particular meaningful employment, in people with a serious mental illness. Gewurtz, Cott, Rush, and Kirsh (see record 2012-34112-003) present findings from a change in policy in Canada for the funding of vocational services for people with a serious mental illness from a fee-for-service model to an outcomes-based model, with reimbursement based on successful competitive job placement and retention, irrespective of job type and consumer preference. The results indicated increased rates of competitive work, mainly in entry-level jobs, but they also raised questions as to whether the narrow focus on job attainment may have been at the cost of less career development and ultimately less meaningful work for the consumers. Baksheev, Allott, Jackson, McGorry, and Killackey (see record 2012-34112-002) found that a combined supported employment and education program for people with a first episode of psychosis led to higher rates of employment and class completion than usual services. The analysis presented in this report showed that no individual consumer characteristics other than program assignment (supported employment and education vs. usual services) predicted vocational or educational outcomes. The findings underscore the potency of supported employment, and suggest that combining it with educational services may be fruitful for people who have recently experienced an episode of psychosis. These findings raise several questions that will be touched on in this editorial, including: Why are career development and supported education important? What have we learned about supported education? What are the current gaps in our knowledge about supported education?

    以西南山区线路中常用的双柱式高墩桥梁为研究对象,建立典型桥跨结构的空间动力分析模型,采用非线性动力时程分析方法,详细研究了考虑地震碰撞效应时桥梁结构的地震响应特性,并探讨了接触单元刚度取值、间隙宽度、桥台刚度以及支座滑动性能等非线性边界条件的影响.结果表明:梁间碰撞作用主要发生在近桥台伸缩缝处,碰撞作用减小桥墩的地震响应,同时在梁体中产生较大的短时加速度脉冲效应;考虑桥台的纵向约束作用将使得梁间碰撞效应增强;对于通常设计采用的间隙宽度范围,强震作用时碰撞现象会不可避免地发生;支座滑动性能对桥墩的地震响应起到隔震的作用,考虑支座滑动性能后梁间碰撞次数减少;各种非线性边界条件因素的综合作用使得桥跨结构的地震响应变得较为复杂,为获得结构真实响应结果应该合理考虑这些因素的影响.%Based on the double-column highway bridges with high-rise piers in southwest mountain area, the spatial dynamic analysis models of representative bridge span were established. The seismic response characteristics of the bridge considering the pounding effect were studied in detail by using nonlinear dynamic time history analysis method. The influence of some nonlinear boundary conditions, including value of contact element stiffness, gap width, abutment stiffness and sliding performance of bearings, were discussed. The results indicate that ( 1 ) the seismic pounding effect between adjacent beams occurs mainly in the expansion joint near the bridge abutments, the pounding reduces the seismic response of piers but generates high magnitude and short duration acceleration pluses in the beams; (2) the pounding effect between adjacent beams will be enhanced when the longitudinal constraint effect of abutments is considered; (3) for the range of gap width usually· adoptod in design, the pounding

From nonlinear time history analyses, the rationality and feasibility of the improved nonlinear static analysis method considering multiple-mode effects is verified by comparing with the average of seismic responses. The practicability of CSM considering SSI for railway bridge aseismic assessment is also verified.%对FEMA356和ATC-40中考虑多自度效应的非线性静力分析法进行改进.并在FEMA440考虑土-结构相互作用能力谱法基础上,以我国西南某铁路特大桥桥墩为研究对象,选取与我国《铁路工程抗震规范》Ⅱ类场地相符合的80条强震记录,利用FEMA440性能点轨迹法求解高柔桥墩结构延性及性能点;并与80条强震记录非线性时程分析计算结果平均值进行比较.验证本文改进的非线性静力分析法反映高柔桥墩多自度效应的合理性,及考虑土-结构相互作用能力谱法在铁路桥梁工程中应用的可行性.

    2014-06-01

    In this column, the author describes how supported employment was a conduit for employment for him, and allowed for a remarkable journey of recovery, involving discovery and empowerment, incorporation, purpose, and belonging. After two decades of unemployment or underemployment, he began to see that work was possible through supported education at college, where he excelled. Federal and state grants paid for two thirds of his college education. He periodically met with a vocational rehabilitation counselor, who was very encouraging. He also had a case manager through a private psychiatric organization who provided support. The author concludes that the root of his problems was the lack of supports to help him become incorporated into society-a lack that ushered in a host of problems, probably similar to what others experience. When supports were given, many of those symptoms disappeared.

    An apparatus and method of using an improved chromatography resin support is disclosed. The chromatography support platform is provided by a stainless steel hollow cylinder adapted for being inserted into a chromatography column. An exterior wall of the stainless steel cylinder defines a groove for carrying therein an "O"-ring. The upper surface of the stainless steel column is covered by a fine stainless steel mesh welded to the edges of the stainless steel cylinder. When placed upon a receiving ledge defined within a chromatography column, the "O"-ring provides a fluid tight seal with the inner edge wall of the chromatography cylinder. The stainless steel mesh supports the chromatography matrix and provides a back flushable support which is economical and simple to construct.

    Gravesen, Jens; Juttler, B.; Sir, Z.

    2008-01-01

    We analyze the class of surfaces which are equipped with rational support functions. Any rational support function can be decomposed into a symmetric (even) and an antisymmetric (odd) part. We analyze certain geometric properties of surfaces with odd and even rational support functions....... In particular it is shown that odd rational support functions correspond to those rational surfaces which can be equipped with a linear field of normal vectors, which were discussed by Sampoli et al. (Sampoli, M.L., Peternell, M., Juttler, B., 2006. Rational surfaces with linear normals and their convolutions...... with rational surfaces. Comput. Aided Geom. Design 23, 179-192). As shown recently, this class of surfaces includes non-developable quadratic triangular Bezier surface patches (Lavicka, M., Bastl, B., 2007. Rational hypersurfaces with rational convolutions.

    2015-04-01

    Peer support groups have a long history and have been shown to improve health outcomes. With the increasing familiarity with online social networks like Facebook and ubiquitous access to the Internet, online social support networks are becoming popular. While studies have shown the benefit of these networks in providing emotional support or meeting informational needs, robust data on improving outcomes such as a decrease in health services utilization or reduction in adverse outcomes is lacking. These networks also pose unique challenges in the areas of patient privacy, funding models, quality of content, and research agendas. Addressing these concerns while creating patient-centred, patient-powered online support networks will help leverage these platforms to complement traditional healthcare delivery models in the current environment of value-based care.

  18. LHC support post

    CERN Multimedia

    1995-01-01

    LHC support post prototype, which dates in 1995, in a long development period which started in the early ’90s and continued until the end of the decade. The wires next to the support post are probably wires from strain gauges, which are employed to measure the stress level in the material when the support is mechanically loaded. These supports are mechanically optimized to withstand a weight of up to 100Kn (10 tons) while being as thin as possible to minimize conduction heat to magnets. This is the reason why the stress measurement was extensively done in the prototyping phase. About support posts: The high magnetic fields needed for the LHC can only be reached using superconductors. At very low temperatures, superconductors have no electrical resistance and therefore no power loss. The LHC will be the largest superconducting installation ever built and, at 1.9 degrees above absolute zero (300 degrees below room temperature), one of the the coldest objects in the universe! The magnet supports have to brid...

    Full Text Available By passing the law on state support in agriculture, fishery and forestry the former support system has been changed. Fishery support beneficiaries can use several kinds of support and help. Former financial stimulations for fishery regulated by law from 1995 to 1st January 2003 were settled by the production stimulation model. Besides that well received model, there are the capital investment model, the support in production insurance, the right to use blue diesel, and granting credit for production of freshwater and saltwater fry, adult fish and shells. These five models of support and help can be used by freshwater and saltwater fish and shell breeders, while for fishing the marine fish the production stimulation model is applied (fishing of small pelagic fish, as well as the capital investment model and right to use blue diesel. Marine and freshwater processors can use the production stimulation and the capital investment model. All these models have in common the fact that all physical and legal entities registered for fishing activities (having licence for commercial fishery, aquaculture (the licence for aquaculture or the one for fish and other marine organisam breeding and processing (having the regulated veterinarian and sanitary conditions, the registration document and having been registered in the List of approved facilities have the right to use them.

    2012-01-01

    A multi-site Randomized-Controlled Trial compared a home-based Supported Speed Treadmill Training Exercise Program (SSTTEP) with a strengthening exercise program in children with cerebral palsy (CP) on the following categories; Participation, quality of life (QOL), self-concept, goal attainment, and satisfaction. Twenty-six children with spastic cerebral palsy were assigned by site-based block randomization to the SSTTEP (n=14) or strengthening exercise (n=12) group. Both groups participated in a two week clinic-based induction period and continued the intervention at home for ten weeks. Data were collected at baseline, post-intervention (12 weeks), and follow-up (16 weeks). Assessments included the Canadian Occupational Performance Measure, Children's Assessment of Participation and Enjoyment Scale, Pediatric Quality of Life Cerebral Palsy Module, and Piers-Harris Children's Self-Concept Scale. Evaluators were blinded to group assignment at two sites. Satisfaction and performance on individual goals, participation, and parent-reported QOL improved in both groups with improvement maintained for four weeks post intervention. The hypothesis that the SSTTEP group would have better outcomes than the exercise group was not supported. However, both groups showed that children with CP can make gains in participation, individual goals, and satisfaction following a 12-week intensive exercise intervention, and these findings persisted for four weeks post intervention.

    MPLS(Multi-Protocol Label Switching) VPN(Virtual Private Network) traffic has been deployed widely, but currently only supports unicast. This paper briefly introduces several available MPLS VPN multicast approaches, and then analyzes their disadvantages. A novel mechanism that uses two-layer label stack to support MPLS VPN explicit multicast is proposed and the process is discussed in detail. The scalability and performance of the proposed mechanism are studied analytically. The result shows that our solution has great advantage over the currently available scheme in terms of saving core network bandwidth and improving the scalability.

    The Gamma-ray Large Area Space Telescope (GLAST) mission will provide the user community with many scientific opportunities. The mission's interface with the user community is the GLAST Science Support Center (GSSC). Yearly guest investigator (GI) cycles will support research related to GLAST. After the first year GIs may propose pointed observations; however, as a consequence of the large field-of-view of GLAST's instruments, pointed observations will rarely have an advantage over the default survey mode. Data, analysis software and documentation will be provided through the GSSC website (http://glast.gsfc.nasa.gov/ssc/); the website also includes a library of scientific results, and a helpdesk.

  4. Starship Life Support

    Science.gov (United States)

    Jones, Harry W.

    2009-01-01

    The design and mass cost of a starship and its life support system are investigated. The mission plan for a multi generational interstellar voyage to colonize a new planet is used to describe the starship design, including the crew habitat, accommodations, and life support. Only current technology is assumed. Highly reliable life support systems can be provided with reasonably small additional mass, suggesting that they can support long duration missions. Bioregenerative life support, growing crop plants that provide food, water, and oxygen, has been thought to need less mass than providing stored food for long duration missions. The large initial mass of hydroponics systems is paid for over time by saving the mass of stored food. However, the yearly logistics mass required to support a bioregenerative system exceeds the mass of food solids it produces, so that supplying stored dehydrated food always requires less mass than bioregenerative food production. A mixed system that grows about half the food and supplies the other half dehydrated has advantages that allow it to breakeven with stored dehydrated food in about 66 years. However, moderate increases in the hydroponics system mass to achieve high reliability, such as adding spares that double the system mass and replacing the initial system every 100 years, increase the mass cost of bioregenerative life support. In this case, the high reliability half food growing, half food supplying system does not breakeven for 389 years. An even higher reliability half and half system, with three times original system mass and replacing the system every 50 years, never breaks even. Growing food for starship life support requires more mass than providing dehydrated food, even for multigeneration voyages of hundreds of years. The benefits of growing some food may justify the added mass cost. Much more efficient recycling food production is wanted but may not be possible. A single multigenerational interstellar voyage to

    1995-01-01

    The present invention is a thin filament embedded in a low density aerogel for use in radiation detection instruments and incandescent lamps. The aerogel provides a supportive matrix that is thermally and electrically nonconductive, mechanically strong, highly porous, gas-permeable, and transparent to ionizing radiation over short distances. A low density, open-cell aerogel is cast around a fine filament or wire, which allows the wire to be positioned with little or no tension and keeps the wire in place in the event of breakage. The aerogel support reduces the stresses on the wire caused by vibrational, gravitational, electrical, and mechanical forces.

    2011-01-01

    The unseating damage to simply supported bridges and their main influencing factors during the Wenchuan earthquake are summarized. It is found that excepting the earthquake-induced landslide hazard, the earthquake surface rupture, near fault ground motion, punching shear failure of the abutment breast wall, the invalidity of the devices for preventing unseating damage to the bridges and the complex bridge types are main influencing factors leading to the unseating damage to the simply supported bridges. Basic seismic design idea and method to prevent unseating damage to simply supported bridges are presented in this paper, which include: (1) sliding between bridge girders and cap beams is allowed to reduce the seismic actions concentrated on the bridge piers; (2) cap beams with enough seating length are recommended for sliding between girder and pier to avoid unseating damage; (3) shear keys or cable restrainers should be used as added measures to prevent unseating damage. The design method for simply supported bridges with cable restrainers is illustrated in detail by using current seismic design code for bridges.%总结了5· 12汶川大地震中简支梁桥落梁震害及主要影响因素,发现除地震山体滑坡等地质灾害外,断层地表破裂、近断层地震动效应、桥台胸墙冲切破坏、防落梁构造措施单一及桥梁体型复杂等因素都是引起简支梁桥落粱震害的重要原因.提出了简支梁桥防落梁设计的基本理念及相关技术方案要点为允许墩梁间发生滑移,以降低桥墩承受的地震惯性力,以及盖梁提供允许的最大滑移长度及支座支承宽度,再辅助挡块或拉索限位器等共同防止落粱发生.最后结合现行规范,以拉索限位器为例给出了简支梁桥防落梁设计方法.

  12. Bioartificial Liver Support

    Directory of Open Access Journals (Sweden)

    Vincent G Bain

    2001-01-01

    Full Text Available Bioartificial liver support has been increasingly the focus of both basic and clinical research in an attempt to replicate the multiplicity of normal liver function. The concept is attractive because, if it is effective, patients with acute liver failure may be supported until native liver regeneration occurs or, by optimizing their condition, until liver transplantation is possible. Current bioartificial liver support systems utilize primary porcine hepatocytes or transformed human hepatocytes, which are housed within a bioreactor, through which the patient's blood or plasma is pumped in an extracorporeal circuit. The optimal source for the hepatocytes is an area of debate; however, a genetically engineered cell line may provide optimal function. Novel three-dimensional matrices that anchor the hepatocytes are being designed to mimic architectural features of the normal liver. Large multicentre, randomized, controlled trials are ongoing following several pilot studies. Serious side effects such as hemodynamic instability and immune reactions have been infrequent. Much controversy, however, surrounds the issue of possible transmission of pig endogenous retrovirus to humans, and current trials are being carefully monitored. Bioartificial liver support is a promising technology, and the results of current and planned studies are awaited with great interest.

    Fasseas, Panayotis; Kutalek, Steven P.; Samuels, Fania L.; Holmes, Elena C.; Samuels, Louis E.

    2002-01-01

    We describe herein the cases of 2 patients who had ventricular arrhythmias. In one, a short-term biventricular assist device, the ABIOMED BVS 5000, was placed because the patient had sustained ventricular tachycardia and could not be weaned from cardiopulmonary bypass. Excellent hemodynamic support was maintained for several days while the antiarrhythmic therapy was maximized. Sinus rhythm was restored, and the patient was successfully weaned from the ventricular assist device. However, the substrate for the arrhythmia persisted, and a recurrence, 1 week later, resulted in the patient's death. In the 2nd patient, the use of an implantable left ventricular assist device was successful in temporarily alleviating the ventricular tachycardia associated with ischemic cardiomyopathy. However, after 2 days of device assistance, the patient experienced a recurrence of the tachycardia, which degenerated into ventricular fibrillation with a marked deterioration in the patient's hemodynamics. The arrhythmia persisted despite multiple attempts at external cardioversion, and internal cardioversion and placement of an automatic implantable cardioverter-defibrillator were necessary. This treatment, along with repeated boluses of amiodarone, led to successful suppression of the arrhythmias, and the patient eventually underwent transplantation. The mechanical hemodynamic support of the circulation by ventricular assist devices was effective in supporting these 2 patients who had sustained ventricular arrhythmias.

    In recent years, administrative support for developmental disabilities, such as Asperger's syndrome, has come to be conspicuous with "Law for Supporting Persons with Developmental Disabilities", which went into effect in 2005, and promotion of "Special Support Education". However, these supports are still insufficient, because administrative support for the Asperger's syndrome in Japan, having just started very recently. Developmental disabilities, such as Asperger's syndrome, are by no means mild as disabilities, it is required to fill up administrative support for them from now on.

  14. Decision Support for Radiologists

    Full Text Available Introduction & Background: Radiology practice like any other discipline in medicine consists of professional problem solving. A practicing radiologist may face different kinds of problems from pathology finding in im-age, suggestion of appropriate workup in a specific situation, formulating relevant differential diagnosis list for comparison with normal variants and artifacts. When a radiologist has the opportunity to use a computer he/she will also be able to use digital material/technology to solve these problems and make sound decisions. The available methods/materials for digital decision support in radiology may be categorized as follow: A. Image Processing When a radiological image is captured or converted to digital format, techniques like edge enhancement and contrast change may improve the diagnostic value of an image and help in decision making. B. Computer-aided Detection Thoracic imaging and mammography are two fields with promising advances in computer-aided diagnosis (CAD. The ultimate role of CAD is as a second opinion besides radiologists own perception. It is obvious how-ever that when available, CAD may decrease detection errors in radiology practice. C. Decision Support Databases Image Banks: An electronic atlas may be used to compare patients’ image to a predefined classified set of im-ages in order to help radiologist in pattern recognition. This may also be used for anatomic details and variants. Knowledge Bases: A digital differential diagnosis table or algorithmic approach to a specific problem may be helpful in reading room. Digital Textbooks: Classical radiological textbooks may be used in routine practice to remember some definitions, lists or hints, When available, digital version of textbooks are invaluable decision aids. D. Internet resources Online resources can be easily updated, widely used by different users, uniformly applied by different radiolo-gists. Although digital decision support materials and

    Cones comprise only a small portion of the photoreceptors in mammalian retinas. However, cones are vital for color vision and visual perception, and their loss severely diminishes the quality of life for patients with retinal degenerative diseases. Cones function in bright light and have higher demand for energy than rods; yet, the mechanisms that support the energy requirements of cones are poorly understood. One such pathway that potentially could sustain cones under basal and stress conditions is macroautophagy. We addressed the role of macroautophagy in cones by examining how the genetic block of this pathway affects the structural integrity, survival, and function of these neurons. We found that macroautophagy was not detectable in cones under normal conditions but was readily observed following 24 h of fasting. Consistent with this, starvation induced phosphorylation of AMPK specifically in cones indicating cellular starvation. Inhibiting macroautophagy in cones by deleting the essential macroautophagy gene Atg5 led to reduced cone function following starvation suggesting that cones are sensitive to systemic changes in nutrients and activate macroautophagy to maintain their function. ATG5-deficiency rendered cones susceptible to light-induced damage and caused accumulation of damaged mitochondria in the inner segments, shortening of the outer segments, and degeneration of all cone types, revealing the importance of mitophagy in supporting cone metabolic needs. Our results demonstrate that macroautophagy supports the function and long-term survival of cones providing for their unique metabolic requirements and resistance to stress. Targeting macroautophagy has the potential to preserve cone-mediated vision during retinal degenerative diseases.

    Mucins are difficult to separate using conventional gel electrophoresis methods such as SDS-PAGE and agarose gel electrophoresis, owing to their large size and heterogeneity. On the other hand, cellulose acetate membrane electrophoresis can separate these molecules, but is not compatible with glycan analysis. Here, we describe a novel membrane electrophoresis technique, termed "supported molecular matrix electrophoresis" (SMME), in which a porous polyvinylidene difluoride (PVDF) membrane filter is used to achieve separation. This description includes the separation, visualization, and glycan analysis of mucins with the SMME technique.

    1983-12-27

    A mine roof support has hydraulic props mounted between a floor sill and a roof bar which can be raised and lowered by extension and retraction of the props. A goaf shield is pivotably connected to the rear of the roof bar and is linked via levers to the floor sill. A hydraulic piston and cylinder unit is connected between the roof bar and the goaf shield. Apparatus serves to prevent damage to the support components, and especially to the unit which could be extended beyond its full stroke when the props are retracted to bring the goaf shield and the roof bar more or less into alignment. The protective apparatus is composed of a compact valve device operated by a member, such as a cam, to block the props from hydraulic pressure when the goaf shield and the roof bar assume a pre-determined angular disposition. Both the valve device and its operating member are disposed in a protected position within chambers formed inside the roof bar and the goaf shield adjacent the pivot connection therebetween.

    The relationship between preoperative malnutrition and morbi-mortality has been documented for years. Despite the existence of tools that allow its detection, and therefore treat this entity, their introduction into clinical practice is not wide-spread. Both perioperative insulin resistance and hyperglycemia are associated with increased perioperative morbidity and length of hospital stay. The intake of carbohydrate-rich drinks 2-4h prior to surgery reduces insulin resistance. In the immediate postoperative period, the enteral route is safe and well tolerated and its early use reduces hospital stay and postoperative complications compared with parenteral nutritional support. Inmunonutrition has been proven effective to decrease postoperative complications and hospital stay. In view of these data we opted for the adoption of these measures replacing bowel rest and the indiscriminate use of postoperative parenteral nutrition.

    The Earth Observation System Data and Information System (EOSDIS) is a large, complex data system currently supporting over 18 operational NASA satellite missions including the flagship EOS missions: Terra, Aqua, and Aura. The observations collected by these missions are kept at geographically distributed data centers. EOSDIS manages over four petabytes of data accessed by over 200,000 distinct users last year. The data centers distributed more than 37 million Earth science data products during 2005 to a diverse customer community. An important goal for these data centers is to provide an adequate service at a uniform level for the user community to ensure we get the most benefit from our investment in space resources. This paper discusses the challenges, the ways the data centers coordinate among themselves to provide service, and recent results of measuring customer satisfaction with this service.

    Important changes or points of emphasis in the recommendations for pediatric advanced life support are as follows. In infants and children with no signs of life, healthcare providers should begin CPR unless they can definitely palpate a pulse within 10 seconds. New evidence documents the important role of ventilations in CPR for infants and children. Rescuers should provide conventional CPR for in-hospital and out-of-hospital pediatric cardiac arrests. The initial defibrillation energy dose of 2 to 4J/kg of either monophasic or biphasic waveform. Both cuffed and uncuffed tracheal tubes are acceptable for infants and children undergoing emergency intubation. Monitoring capnography/capnometry is recommended to confirm proper endotracheal tube position.

    2002-11-01

    As increases in criminal activity collide with more aggressive law enforcement postures, there is more contact between police officers and violent felons. Civilian law enforcement special operations teams routinely engage suspects in these violent, dynamic, and complex interdiction activities. Along with these activities comes the substantial and foreseeable risk of death or grievous harm to law officers, bystanders, hostages, or perpetrators. Further, law enforcement agencies who attempt to apprehend dangerous, heavily armed criminals with a special operations team that lacks the expertise to treat the medical consequences that may arise from such a confrontation may be negligent of deliberate indifference. Meanwhile, evidence exists within the military, civilian law enforcement, and medical literature that on-scene TEMS serves to improve mission success and team safety and health, while decreasing morbidity and mortality in the event of an injury or illness suffered during operations. National professional organizations within law enforcement and emergency medicine have identified and support the fundamental need for mission safety and the development of a standard model to train and incorporate TEMS into law enforcement special operations. The overall objective of TEMS is to minimize the potential for injury and illness and to promote optimal medical care from the scene of operations to a definitive care facility. The design, staffing, and implementation of a TEMS program that maximally uses the community resources integrates previously disparate law enforcement, EMS, and emergency medical/trauma center functions to form a new continuum of care [55].

    2010-12-01

    Climate change research, and glaciology in particular, has increasingly embraced seismology in recent years. The NSF supported IRIS/PASSCAL Instrument Center is working with researchers to develop the unique instruments and techniques for collecting data in this challenging environment. Global concern with sea level change along with strategic interests of the US government and other nations is driving a large investment in glaciological climate research. A number of groups have demonstrated new seismologically-derived constraints on glaciological conditions and processes. Environmental challenges include remote and precarious locations, necessitating robust yet quickly deployable seismic stations and long periods of autonomous operation. Temperature extremes and the possibility of immersion from large annual snow loads, resulting in a deployment surface that can vary from 50 feet of snow cover to bare ice with large melt pools in a single season are additional major challenges. There is also an urgency created by studies indicating that the high latitude continental ice sheets are metastable and that behavior is changing now. Scientists are presently commonly utilizing adaptations of available instrumentation designed for low latitude and milder field conditions as appropriate, but seek better, more capable, and more flexible solutions, including integration of environmental sensors and real-time data telemetry and station control as some of these experiments evolve into a monitoring effort. Seismic instrumentation is only produced by a small number of companies and, innovation for new instruments takes time and requires substantial investment. While pursuing longer-term innovation funding strategies, we are also adapting current instrumentation paradigms to glaciological use (e.g., by leveraging the cold instrument development for research in Antarctica during the IPY). We are also encouraging industrial partners to respond to these demands and challenges with

    The objective of the CERTS Microgrid Laboratory Test Bed project was to enhance the ease of integrating small energy sources into a microgrid. The project accomplished this objective by developing and demonstrating three advanced techniques, collectively referred to as the CERTS Microgrid concept, that significantly reduce the level of custom field engineering needed to operate microgrids consisting of small generating sources. The techniques comprising the CERTS Microgrid concept are: 1) a method for effecting automatic and seamless transitions between grid-connected and islanded modes of operation; 2) an approach to electrical protection within the microgrid that does not depend on high fault currents; and 3) a method for microgrid control that achieves voltage and frequency stability under islanded conditions without requiring high-speed communications. The techniques were demonstrated at a full-scale test bed built near Columbus, Ohio and operated by American Electric Power. The testing fully confirmed earlier research that had been conducted initially through analytical simulations, then through laboratory emulations, and finally through factory acceptance testing of individual microgrid components. The islanding and resychronization method met all Institute of Electrical and Electronics Engineers 1547 and power quality requirements. The electrical protections system was able to distinguish between normal and faulted operation. The controls were found to be robust and under all conditions, including difficult motor starts. The results from these test are expected to lead to additional testing of enhancements to the basic techniques at the test bed to improve the business case for microgrid technologies, as well to field demonstrations involving microgrids that involve one or mroe of the CERTS Microgrid concepts.

    Although evidence suggests the importance of social support for refugees, this knowledge has not been invoked to systematically develop culturally congruent support interventions that help refugees adapt to life in receiving countries. The objective of this study was to design and pilot test a culturally congruent intervention that meets the support needs and preferences of two ethno-culturally distinct refugee groups. Support was delivered to Somali and Sudanese refugees (n = 58), by trained peer and professional facilitators. Face-to-face groups comprised of refugees, matched by gender and ethnicity, were created to enhance the depleted social networks of Somali and Sudanese refugees. Each peer support group met bi-weekly for a face-to-face session for 12 weeks. Peer facilitators delivered supplementary one-to-one support via the telephone. The ingredients of the support intervention included: (i) peer facilitators and professionals; (ii) provision of information, affirmation and emotional support; and (iii) accessibility (e.g. childcare, transportation). The study employed a qualitative participatory research design. Data collected for the study included (i) in-depth pre-intervention interviews with potential support group participants in 2008-2009 to assess intervention preferences; (ii) fieldnotes by peer and professional facilitators during the intervention in 2009-10; (iii) post-intervention group interviews with support group participants in 2010; and (iv) in-depth interviews with peer and professional helpers in 2010. A major perceived benefit of the support programme was connecting with people from African refugee participants' cultural communities. Participants appreciated the gender and culture-specific groups. Following the social support intervention, refugees reported increased social integration, decreased loneliness and expanded coping repertoire.

    In 1999, an international collaborative initiative for the development of advanced (Generation IV) reactors was started. The idea behind this effort was to bring nuclear energy closer to the needs of sustainability, to increase proliferation resistance, and to support concepts able to produce energy (both electricity and process heat) at competitive costs. The U.S. Department of Energy has supported this effort by pursuing the development of the Next Generation Nuclear Plant, a high temperature gas-cooled reactor. This support has included research and development of pertinent data, initial regulatory discussions, and engineering support of various codes and standards development. This report discusses the various applicable American Society of Mechanical Engineers (ASME) codes and standards that are being developed to support these high temperature gascooled reactors during construction and operation. ASME is aggressively pursuing these codes and standards to support an international effort to build the next generation of advanced reactors so that all can benefit.

    In 1999, an international collaborative initiative for the development of advanced (Generation IV) reactors was started. The idea behind this effort was to bring nuclear energy closer to the needs of sustainability, to increase proliferation resistance, and to support concepts able to produce energy (both electricity and process heat) at competitive costs. The U.S. Department of Energy has supported this effort by pursuing the development of the Next Generation Nuclear Plant, a high temperature gas-cooled reactor. This support has included research and development of pertinent data, initial regulatory discussions, and engineering support of various codes and standards development. This report discusses the various applicable American Society of Mechanical Engineers (ASME) codes and standards that are being developed to support these high temperature gascooled reactors during construction and operation. ASME is aggressively pursuing these codes and standards to support an international effort to build the next generation of advanced reactors so that all can benefit.

    2011-01-01

    The bored pile foundation of pylon pier No. 3 of Anqing Changjiang River Railway Bridge was constructed with the circular double-wall steel boxed cofferdam. To realize the accurate positioning and construction safety of the cofferdam, through comparison of the different schemes, it was decided that the cofferdam would be positioned by the mooring system from the front and rear positioning barges without utilizing guiding barge. The types and numbers of the mooring anchors, the mooring ropes and positioning barges were determined according to the calculation of the total tensile force of the main anchors and the force of each anchor after sinking thecofferdam in place. In the design, the problem of steering and reeling of the large diameter mooring ropes was tackled by the tie points on the sides of the cofferdam and by the one-way or multi-way rolling fairleaders set at the top of the cofferdam. The side anchors were heaved by the winches installed on the anchor weighing platforms on the front and rear positioning barges and at the top of the cofferdam and the anchors could be therefore cast, weighed and changed. The side anchors on the shore and ground anchors were embedded in the excavated pits and the anchors under water were cast by the 240 t barge. The mooring ropes were timely tied, untied, tightened and the anchors were adjusted in pace of sinking of the cofferdam to finally complete the construction of the mooring system.%安庆长江铁路大桥3号桥塔墩钻孔桩基础采用圆形双壁钢套箱围堰施工.为实现围堰的精确定位和施工安全,经方案比较采用无导向船的前、后定位船锚碇系统定位方案,锚型与数量、锚绳及定位船通过计算围堰下沉到位后主锚总拉力及各锚碇受力确定.设计中通过在围堰侧面的边锚拉结点及围堰顶面设置单向或多向转动的辊轴式马口解决大直径锚绳转向和收放难题;通过在前、后定位船和围堰顶的收锚平台上安装

    Dunkel-Schetter, C; Folkman, S; Lazarus, R S

    1987-07-01

    Psychological correlates of social support receipt were examined in an investigation of stress and coping among 150 middle-aged community residents. Subjects were interviewed monthly for 6 months, each time concerning a specific stressful situation in the previous month. Social support received and methods of coping were assessed each time, as well as other variables. Factors hypothesized to be associated with support receipt were person predispositions, appraisal patterns with regard to specific stressful encounters, and coping strategies used. Each was most strongly associated with a particular type of social support. Person predispositions related most strongly to emotional support received, appraisal factors related most strongly to aid, and coping strategies related most to informational support received. Furthermore, of the three sets of variables, the individual's ways of coping appeared to be most strongly associated with all types of social support received. Two implications are explored. First, we suggest that the three types of social support studied represent different constructs with different antecedents and consequences. Second, we argue that coping behavior provides interpersonal cues regarding what is wanted or needed in a stressful situation and that the members of the social environment respond accordingly.

    Grid user support is a challenging task due to the distributed nature of the Grid. The variety of users and Virtual Organisations adds further to the challenge. Support requests come from Grid beginners, from users with specific applications, from site administrators, or from Grid monitoring operators. With the GGUS infrastructure, EGEE provides a portal where users can find support in their daily use of the Grid. The current use of the system shows that the goal has been achieved with success. The Grid user support model in EGEE can be captioned "regional support with central coordination". This model is realised through a support process which is clearly defined and involves all the parties that are needed to run a project-wide support service. This process is sustained by a help desk system which consists of a central platform integrated with several satellite systems belonging to the Regional Operations Centres (ROCs) and the Virtual Organisations (VOs).

    This article reviews the international English-language literature on social support and caregiving in gerontology since the early 1990s. The literature has grown, but consensus on the terms' meaning and measurement is lacking. Interest is ongoing in practical help, in benefits of social support, and in demands and negative outcomes for caregivers, with growing but less emphasis on more theoretical questions, on negative outcomes from the receipt of support, and on positive consequences of providing care. Nevertheless, social support is duly recognized as a social determinant of health and receiving attention at policy levels - both are significant shifts from two decades ago and add to the interest this area will receive from researchers in coming decades. There remain many unanswered questions regarding the changing societal context, but it is clear that the social support of others - throughout our lives including old age - will continue in the future, albeit in ever-changing forms.

    2015-12-01

    The geoscience student population in the United States today does not reflect the diversity of the US population. Not only does this challenge our ability to educate sufficient numbers of students in the geosciences, it also challenges our ability to address issues of environmental justice, to bring geoscience expertise to diverse communities, and to pursue a research agenda reflecting the needs and interests of our nation as a whole. Programs that are successful in supporting students from underrepresented groups attend to the whole student (Jolly et al, 2004) as they develop not only knowledge and skills, but a sense of belonging and a drive to succeed in geoscience. The whole student approach provides a framework for supporting the success of all students, be they members of underrepresented groups or not. Important aspects of support include mentoring and advising, academic support, an inclusive learning community, and opportunities to learn about the profession and to develop geoscience and professional skills. To successfully provide support for the full range of students, it is critical to consider not only what opportunities are available but the barriers different types of students face in accessing these opportunities. Barriers may arise from gaps in academic experiences, crossing into a new and unfamiliar culture, lack of confidence, stereotype threat, implicit bias and other sources. Isolation of geoscience learning from its application and social context may preferentially discourage some groups. Action can be taken to increase support for all students within an individual course, a department or an institution. The InTeGrate STEP Center for the Geosciences, the Supporting and Advancing Geoscience Education at Two-Year Colleges program and the On the Cutting Edge Professional Development for Geoscience Faculty program all provide resources for individuals and departments including on line information, program descriptions, and workshop opportunities.

    DeLegge, Mark Henry; Kelly, Andrea True; Kelley, Andrea True

    2013-12-01

    The incidence of malnutrition in hospitalized patients is relatively high (up to 55%) despite breakthroughs in nutrition support therapies. These patients have increased morbidity and mortality, extended hospital stays, and care that is associated with higher costs. These patients are often poorly managed due to inadequate nutrition assessment and poor medical knowledge and practice in the field of nutrition. Nutrition support teams (NSTs) are interdisciplinary support teams with specialty training in nutrition that are often comprised of physicians, dietitians, nurses, and pharmacists. Their role includes nutrition assessment, determination of nutrition needs, recommendations for appropriate nutrition therapy, and management of nutrition support therapy. Studies have demonstrated significant improvements in patient nutrition status and improved clinical outcomes as well as reductions in costs when patients were appropriately managed by a multispecialty NST vs individual caregivers. Despite this, there has been steady decline in the number of formal NST in recent years (65% of hospitals in 1995 to 42% in 2008) as hospitals and other healthcare organizations look for ways to cut costs. Given the importance of nutrition status on clinical outcomes and overall healthcare costs, a number of institutions have introduced and sustained strong nutrition training and support programs and teams, demonstrating both clinical and economic benefit. The benefits of NST, training and implementation strategies, and tips for justifying these clinically and economically beneficial groups to healthcare organizations and governing bodies are discussed in this review.

  16. Multiscale Modeling of supported bilayers

    Supported Lipid Bilayers are an abundant research platform for understanding the behavior of real cell membranes as they allow for additional mechanical stability. We studied systematically the changes that a support induces on a phospholipid bilayer using coarse-grained molecular modeling on different levels. We characterize the density and pressure profiles as well as the density imbalance inflicted on the membrane by the support. We also determine the diffusion coefficients and characterize the influence of different corrugations of the support. We then determine the free energy of transfer of phospholipids between the proximal and distal leaflet of a supported membrane using the coarse-grained Martini model. It turns out that there is at equilibrium about a 2-3% higher density in the proximal leaflet. These results are in favorable agreement with recent data obtained by very large scale modeling using a water free model where flip-flop can be observed directly. We compare results of the free energy of transfer obtained by pulling the lipid across the membrane in different ways. There are small quantitative differences but the overall picture is consistent. We are additionally characterizing the intermediate states which determine the barrier height and therefore the rate of translocation.

  17. Advanced Life Support Project Plan

    Science.gov (United States)

    2002-01-01

    Life support systems are an enabling technology and have become integral to the success of living and working in space. As NASA embarks on human exploration and development of space to open the space frontier by exploring, using and enabling the development of space and to expand the human experience into the far reaches of space, it becomes imperative, for considerations of safety, cost, and crew health, to minimize consumables and increase the autonomy of the life support system. Utilizing advanced life support technologies increases this autonomy by reducing mass, power, and volume necessary for human support, thus permitting larger payload allocations for science and exploration. Two basic classes of life support systems must be developed, those directed toward applications on transportation/habitation vehicles (e.g., Space Shuttle, International Space Station (ISS), next generation launch vehicles, crew-tended stations/observatories, planetary transit spacecraft, etc.) and those directed toward applications on the planetary surfaces (e.g., lunar or Martian landing spacecraft, planetary habitats and facilities, etc.). In general, it can be viewed as those systems compatible with microgravity and those compatible with hypogravity environments. Part B of the Appendix defines the technology development 'Roadmap' to be followed in providing the necessary systems for these missions. The purpose of this Project Plan is to define the Project objectives, Project-level requirements, the management organizations responsible for the Project throughout its life cycle, and Project-level resources, schedules and controls.

  20. Supporting Multiple Cognitive Processing Styles Using Tailored Support Systems

    Energy Technology Data Exchange (ETDEWEB)

    Tuan Q. Tran; Karen M. Feigh; Amy R. Pritchett

    2007-08-01

    According to theories of cognitive processing style or cognitive control mode, human performance is more effective when an individual’s cognitive state (e.g., intuition/scramble vs. deliberate/strategic) matches his/her ecological constraints or context (e.g., utilize intuition to strive for a "good-enough" response instead of deliberating for the "best" response under high time pressure). Ill-mapping between cognitive state and ecological constraints are believed to lead to degraded task performance. Consequently, incorporating support systems which are designed to specifically address multiple cognitive and functional states e.g., high workload, stress, boredom, and initiate appropriate mitigation strategies (e.g., reduce information load) is essential to reduce plant risk. Utilizing the concept of Cognitive Control Models, this paper will discuss the importance of tailoring support systems to match an operator's cognitive state, and will further discuss the importance of these ecological constraints in selecting and implementing mitigation strategies for safe and effective system performance. An example from the nuclear power plant industry illustrating how a support system might be tailored to support different cognitive states is included.

  1. The Support to an Entrepreneur

    Directory of Open Access Journals (Sweden)

    Marie-Noëlle Albert

    2013-06-01

    Full Text Available Entrepreneurs are often associated with autonomy, but one of the coauthors, the sole owner of a microbusiness, had a different experience. Based on this, we used an autobiographical narrative method in a constructivist paradigm to explore this phenomenon that is autonomy. The coauthor’s different experience developed the idea that difficulties lived by an entrepreneur can transform autonomy into dependence. This negative complex process is grounded on a request for help by the entrepreneur and the dissymmetric relation between the person who needs help and the support. This kind of relationship promotes a loss of the entrepreneur’s capacities. A non-co-construction of solution (by the entrepreneur and the support is not only less productive, but could also develop a very negative process. This finding is important to better understand support to entrepreneurs.

    This project is aimed to support external users for the effective use of HANARO. The total number of projects selected as the beneficiary of the supporting program by MEST was 21 including this project in this year. We supported 2,339 hr measurements for the 31 requests of the 14 projects selected on the field of neutron beam utilization. In the field of materials and nuclear fuel irradiation test the 3 projects were selected and supported for 80 samples. In the fields of neutron activation analysis and radioisotope production the number of selected and supported projects were 1 and 2 respectively. In order to broaden potential user base, maximize instrument utilization, and enhance cooperation with industries, universities and institutes, practice-oriented HANARO user training courses were held for neutron beam utilization and materials and nuclear fuel irradiation fields. In the fields of neutron activation analysis 3 times training courses were held for the university students. The online neutron beam time allocation system was developed and applied successfully for the HRPD in this year. We are planing to apply this system to other neutron beam instruments in the near future. This project is a kind of the user-based supporting program for the maximize of HANARO utilization. The development products and the ideas and suggestions of users obtained through this projects will be collected and applied to the development of next new facilities. Also, by using the 'HANARO utilization and research information management system(HANARO4U)' we construct the research network among users at industries, universities and institutes. This network is expected to increase HANARO utilization and enhance productivity of the facilities.

    To enable collaboration on the daily tasks involved in scientific research, collaborative frameworks should provide lightweight and ubiquitous components that support a wide variety of interaction modes. We envision a collaborative environment as one that provides a persistent space within which participants can locate each other, exchange synchronous and asynchronous messages, share documents and applications, share workflow, and hold videoconferences. We are developing the Pervasive Collaborative Computing Environment (PCCE) as such an environment. The PCCE will provide integrated tools to support shared computing and task control and monitoring. This paper describes the PCCE and the rationale for its design.

    1990-01-01

    A decision support system (DSS) shell is being constructed that can support applications in a variety of fields, e.g., engineering, manufacturing, finance. The shell provides a hypertext-style interface for 'navigating' among DSS application models, data, and reports. The traditional notion of hypertext had to be enhanced. Hypertext normally requires manually, pre-defined links. A DSS shell, however, requires that hypertext connections to be built 'on the fly'. The role of hypertext is discussed in augmenting DSS applications and the decision making process. Also discussed is how hypertext nodes, links, and link markers tailored to an arbitrary DSS application were automatically generated.

    Full Text Available The creation and operation of a distance education support infrastructure requires the collaboration of virtually all administrative departments whose activities deal with students and faculty, and all participating academic departments. Implementation can build on where the institution is and design service-oriented strategies that strengthen institutional support and commitment. Issues to address include planning, faculty issues and concerns, policies and guidelines, approval processes, scheduling, training, publicity, information-line operations, informational materials, orientation and registration processes, class coordination and support, testing, evaluations, receive site management, partnerships, budgets, staffing, library and e-mail support, and different delivery modes (microwave, compressed video, radio, satellite, public television/cable, video tape and online. The process is ongoing and increasingly participative as various groups on campus begin to get involved with distance education activities. The distance education unit must continuously examine and revise its processes and procedures to maintain the academic integrity and service excellence of its programs. It’s a daunting prospect to revise the way things have been done for many years, but each department has an opportunity to respond to new ways of serving and reaching students.

  6. Memory mechanisms supporting syntactic comprehension

    2013-01-01

    Efforts to characterize the memory system that supports sentence comprehension have historically drawn extensively on short-term memory as a source of mechanisms that might apply to sentences. The focus of these efforts has changed significantly in the past decade. As a result of changes in models of short-term working memory (ST-WM) and developments in models of sentence comprehension, the effort to relate entire components of an ST-WM system, such as those in the model developed by Baddeley (Nature Reviews Neuroscience 4: 829–839, 2003) to sentence comprehension has largely been replaced by an effort to relate more specific mechanisms found in modern models of ST-WM to memory processes that support one aspect of sentence comprehension—the assignment of syntactic structure (parsing) and its use in determining sentence meaning (interpretation) during sentence comprehension. In this article, we present the historical background to recent studies of the memory mechanisms that support parsing and interpretation and review recent research into this relation. We argue that the results of this research do not converge on a set of mechanisms derived from ST-WM that apply to parsing and interpretation. We argue that the memory mechanisms supporting parsing and interpretation have features that characterize another memory system that has been postulated to account for skilled performance—long-term working memory. We propose a model of the relation of different aspects of parsing and interpretation to ST-WM and long-term working memory. PMID:23319178

    There is urgent need to effectively support the well-being of rural palliative family caregivers (FCGs). A mixed method study was conducted with 23 FCGs. Data collection included completion of an assessment questionnaire and semistructured interviews. The most prevalent needs identified by questionnaire were caring for the patient's pain, fatigue, body, and nourishment; FCG's fatigue and need for respite. Yet few FCGs wanted more attention to these needs by healthcare providers. FCGs resisted considering their own personal needs. Instead, they focused on needs related to providing care including to be(come) a palliative caregiver, be skilled and know more, navigate competing wishes, needs, demands, and priorities, and for "an extra pair of hands." Gaps in rural palliative services contributed to low expectations for assistance; reluctance to seek assistance was influenced by FCGs' resourcefulness and independence. Findings suggest that supporting FCGs will most likely be successful when framed in relation to their caregiving role.

    This contract provided core support for activities of the advisory committee of experts comprising the Board on Radiation Effects Research (BRER), in The National Academies' Division on Earth and Life Studies. That committee met two times during the funding period. The committee members provided oversight and advice regarding ongoing BRER projects and also assisted in the identification of potential committee members for new studies and the development of proposals for projects in the radiation sciences worthy for future study. In addition, funding provided support for the planning, advertisement, and invited speakers' travel-expense reimbursement for the Third and Fourth Gilbert W. Beebe Symposia held at The National Academies on December 1, 2004 and on November 30, 2005, respectively.

    A couple of years ago, ST division created a first structure for the support of the LHC experiments, aiming to co-ordinate all the activities which traditionally were in the divisional mandate, like civil engineering, cooling and ventilation cranes and transports, electricity, etc. A picture of the last few months activity, mainly concentrated on the CMS experience, shows that synergies between project managers, personnel involved and group structures can strongly improve the service level in the specific divisional domains. A closer collaboration also seemed to facilitate the development of further opportunities tied to the competence available in the groups and of great interest to the experiments, like the participation of the design of the cooling system of several sub-detectors for the compact muon solenoid, as TK, EE, EB, SE, etc. The exponential increase of the demand confirms the divisional support as a real CERN need in this area, but also pushes ST to understand this dynamic environment and follow t...

    Our ontology-based benchmarking infrastructure for hospitals, we presented on the eHealth 2012, has meanwhile proven useful. Besides, we gathered manifold experience in supporting knowledge discovery in medicine. This also led to further functions and plans with our software. We could confirm and extent our experience by a literature review on the knowledge discovery process in medicine, visual analytics and data mining and drafted an according approach for extending our software. We validated our approach by exemplarily implementing a parallel-coordinate data visualization into our software and plan to integrate further algorithms for visual analytics and machine learning to support knowledge discovery in medicine in diverse ways. This is very promising but can also fail due to technical or organizational details.

    The Supportive Music and Imagery Method is derived from the Bonny Method of Guided Imagery and Music (BMGIM. It uses one piece of pre-recorded music that is short and simple in all musical elements and non-classical music is often used.It aims at enhancing one’s ego by supporting one’s positive resource rather than exploring problems and issues. It is containing and highly structured compared to BMGIM and it focuses on the here-and-now.

    I will introduce how the SMI method is conducted by illustrating a few case examples supervised by me and conducted by graduates and trainees of the Music and Imagery training in Korea.

    During my 2015 internship at Stennis Space Center (SSC) I supported the development of a web based tool to enable user interaction with a low-cost environmental monitoring buoy called the DRIFTER. DRIFTERs are designed by SSC's Applied Science and Technology Projects branch and are used to measure parameters such as water temperature and salinity. Data collected by the buoys help verify measurements by NASA satellites, which contributes to NASA's mission to advance understanding of the Earth by developing technologies to improve the quality of life on or home planet. My main objective during this internship was to support the development of the DRIFTER by writing web-based software that allows the public to view and access data collected by the buoys. In addition, this software would enable DRIFTER owners to configure and control the devices.

    We show that the stopping criteria used in many support vector machine (SVM) algorithms working on the dual can be interpreted as primal optimality bounds which in turn are known to be important for the statistical analysis of SVMs. To this end we revisit the duality theory underlying the derivation of the dual and show that in many interesting cases primal optimality bounds are the same as known dual optimality bounds.

    Dyscalculia is a learning need that requires assessment and provision of reasonable adjustments. Although there have been numerous discussions about how to identify, assess and support dyscalculic children, there is less information available covering further and higher education, and even less concerned with the education of health professionals. This article aims to address this deficit, to discuss the disparity often felt by educators, and to raise awareness of the impact of dyscalculia on student nurses.

    2004-06-24

    The purpose of this revision of the System Design Description (SDD) is to establish requirements that drive the design of the electrical support system and their bases to allow the design effort to proceed to License Application. This SDD is a living document that will be revised at strategic points as the design matures over time. This SDD identifies the requirements and describes the system design as they exist at this time, with emphasis on those attributes of the design provided to meet the requirements. This SDD has been developed to be an engineering tool for design control. Accordingly, the primary audience/users are design engineers. This type of SDD both ''leads'' and ''trails'' the design process. It leads the design process with regard to the flow down of upper tier requirements onto the system. Knowledge of these requirements is essential in performing the design process. The SDD trails the design with regard to the description of the system. The description provided in the SDD is a reflection of the results of the design process to date. Functional and operational requirements applicable to electrical support systems are obtained from the ''Project Functional and Operational Requirements'' (F&OR) (Siddoway 2003). Other requirements to support the design process have been taken from higher-level requirements documents such as the ''Project Design Criteria Document'' (PDC) (Doraswamy 2004), and fire hazards analyses. The above-mentioned low-level documents address ''Project Requirements Document'' (PRD) (Canon and Leitner 2003) requirements. This SDD contains several appendices that include supporting information. Appendix B lists key system charts, diagrams, drawings, and lists, and Appendix C includes a list of system procedures.

    The extent of flood and inundation, the impacts on people and infrastructure, and generally the situational awareness on all scales for decision making are areas where NASA is mobilizing scientific results, advanced sensing and technologies, experts and partnerships to support response. NASA has targeted mature application science and ready technology for flood and inundation monitoring and assessment. This includes supporting timely data management and product dissemination with users and partners. Requirements are captured in the form of science-area questions, while solutions measure readiness for use by considering standard tools and approaches that make information more accessible, interoperable, understandable and reliable. The program collaborates with capacity building and areas of education and outreach needed to create and leverage non-traditional partnerships in transdisciplinary areas including socio-economic practice, preparedness and resilience assessment, early warning and forecast response, and emergency management, relief and recovery. The program outcomes also seek alignment with and support to global and community priorities related to water resources and food security. This presentation will examine the achievements of individual projects and the challenges and opportunities of more comprehensive and collaborative teams behind NASA's response to global flooding. Examples from recent event mobilization will be reviewed including to the serious of domestic floods across the south and Midwest United States throughout 2015 and 2016. Progress on the combined use of optical, microwave and SAR remote sensing measurements, topographic and geodetic data and mapping, data sharing practices will be reviewed. Other response case studies will examine global flood events monitored, characterized and supported in various boundary regions and nations. Achievements and future plans will be described for capabilities including global flood modeling, near real

    Life support systems for long-term space missions or extraterrestrial installations have to fulfill major functions such as purification of water and regeneration of atmosphere as well as the generation of food and energy. For almost 60 years ideas for biological life support systems have been collected and various concepts have been developed and tested. Microalgae as photosynthetic organisms have played a major role in most of these concepts. This review deals with the potentials of using eukaryotic microalgae for life support systems and highlights special requirements and frame conditions for designing space photobioreactors especially regarding illumination and aeration. Mono- and dichromatic illumination based on LEDs is a promising alternative for conventional systems and preliminary results yielded higher photoconversion efficiencies (PCE) for dichromatic red/blue illumination than white illumination. Aeration for microgravity conditions should be realized in a bubble-free manner, for example, via membranes. Finally, a novel photobioreactor concept for space application is introduced being parameterized and tested with the microalga Chlamydomonas reinhardtii. This system has already been tested during two parabolic flight campaigns.

    Full Text Available BACKGROUND: The text deals with terminology issues from an interdisciplinary point of view. It is based on two different disciplines, law and kinanthropology, in an area of their overlap. AIM: The aim of the author is to point out some possible legislative problems, which could arise due to the current reading of the sport supporting act (Act no. 115/2001. The second aim of the author is to contribute to the discussion of kinantropologists (possibly also the educational researchers and lawyers and to stress the importance of the systematic approach to terminology formulation. METHODS: The author uses the method of language interpretation. We also use the basic analytical methods, induction and deduction, while we stress the systematic approach to the term formulation. RESULTS: The analysis of the sport supporting act terminology shows some specific legislative problems, which could arise due to the definition of sport in the sport supporting act. The author discusses a possible alternative solution. CONCLUSION: According to the opinion of the author, clear, obvious and unified terminology of kinantropologists as specialists in their discipline should represent a source, from which other sciences could derive their terminology. Defined and inexpert terminology used in other disciplines should not be used as an argument for its adopting in kinanthropology.

    Activities this summer consisted of two projects that involved computer simulation of bioregenerative life support systems for space habitats. Students in the Space Life Science Training Program (SLSTP) used the simulation, space station, to learn about relationships between humans, fish, plants, and microorganisms in a closed environment. One student complete a six week project to modify the simulation by converting the microbes from anaerobic to aerobic, and then balancing the simulation's life support system. A detailed computer simulation of a closed lunar station using bioregenerative life support was attempted, but there was not enough known about system restraints and constants in plant growth, bioreactor design for space habitats and food preparation to develop an integrated model with any confidence. Instead of a completed detailed model with broad assumptions concerning the unknown system parameters, a framework for an integrated model was outlined and work begun on plant and bioreactor simulations. The NASA sponsors and the summer Fell were satisfied with the progress made during the 10 weeks, and we have planned future cooperative work.

    Wildfires are regularly occurring emergency events that threaten life, property, and natural resources in every U.S. State and many countries around the world. Despite projections that $1.8 billion will be spent by U.S. Federal agencies alone on wildfires in 2014, the decades-long trend of increasing fire size, severity, and cost is expected to continue. Furthermore, the enormous potential for UAS (and concomitant sensor systems) to serve as geospatial intelligence tools to improve the safety and effectiveness of fire management, and our ability to forecast fire and smoke movements, remains barely tapped. Although orbital sensor assets are can provide the geospatial extent of wildfires, generally those resources are limited in use due to their spatial and temporal resolution limitations. These two critical elements make orbital assets of limited utility for tactical, real-time wildfire management, or for continuous scientific analysis of the temporal dynamics related to fire energy release rates and plume concentrations that vary significantly thru a fire's progression. Large UAS platforms and sensors can and have been used to monitor wildfire events at improved temporal, spatial and radiometric scales, but more focus is being placed on the use of small UAS (sUAS) and sensors to support wildfire observation strategies. The use of sUAS is therefore more critical for TACTICAL management purposes, rather than strategic observations, where small-scale fire developments are critical to understand. This paper will highlight the historical development and use of UAS for fire observations, as well as the current shift in focus to smaller, more affordable UAS for more rapid integration into operational use on wildfire events to support tactical observation strategies, and support wildfire science measurement inprovements.

    Memory limitations are always a focus of computer architecture. The live range aware cache(LIRAC) offers a way to reduce memory access using live range information. In the LIRAC system, scratch data need not be written back if the data will no longer be used. Three kinds of software support developed for LIRAC architecture use compiler analyses, binary analyses, and trace analyses. Trace analysis results show that LIRAC can eliminate 29% of cache write-backs on average and up to 83% in the best case for the SPEC CPU 2000 benchmark. These software techniques can show the feasibility and potential benefit of the LIRAC architecture.

    2014-01-01

    Stroke is a public health problem of the first order. In developed countries is one of the leading causes of death, along with cardiovascular disease and cancer. In addition, stroke is the leading cause of permanent disability in adulthood. Many of the patients who survive do so with significant sequelae that limit them in their activities of daily living. Most strokes (80-85%) are due to ischemia, while the rest are hemorrhagic. We have identified many modifiable risk factors, some with an important relationship with dietary factors or comorbidities in wich the diet has a significant impact. The incidence of malnutrition in stroke patients is not well known, but most likely impacts on patient prognosis. Furthermore, the nutritional status of patients admitted for stroke often deteriorates during hospitalization. It is necessary to perform a nutritional assessment of the patient in the early hours of admission, to determine both the nutritional status and the presence of dysphagia. Dysphagia, through alteration of the safety and efficacy of swallowing, is a complication that has an implication for nutritional support, and must be treated to prevent aspiration pneumonia, which is the leading cause of mortality in the stroke patient. Nutritional support should begin in the early hours. In patients with no or mild dysphagia that can be controlled by modifying the texture of the diet, they will start oral diet and oral nutritional supplementation will be used if the patient does not meet their nutritional requirements. There is no evidence to support the use of nutritional supplements routinely. Patients with severe dysphagia, or decreased level of consciousness will require enteral nutrition. Current evidence indicates that early nutrition should be initiated through a nasogastric tube, with any advantages of early feeding gastrostomy. Gastrostomy will be planned when the enteral nutrition support will be expected for long-term (4 weeks). Much evidence points to the

    2014-01-01

    De Rham cohomology with spacelike compact and timelike compact supports has recently been noticed to be of importance for understanding the structure of classical and quantum field theories on curved spacetimes. We compute these cohomology groups for globally hyperbolic spacetimes in terms of their standard de Rham cohomologies. The calculation exploits the fact that the de Rham-d'Alambert wave operator can be extended to a chain map that is homotopic to zero and that its causal Green function fits into a convenient exact sequence. This method extends also to the Calabi (or Killing-Riemann-Bianchi) complex and possibly other differential complexes. We also discuss generalized causal structures and functoriality.

The concepts presented in this article have tried to stress the importance of anchorage control in orthodontic cases, some problems associated with traditional means to augment orthodontic anchorage, the rationale for developing a skeletal anchorage unit based on endosseous implant technology, and the effectiveness of the onplant as an anchorage unit. Cephalometric superimpositions are most likely the best method to determine the effectiveness of the onplant's contribution to anchorage control and have been included here to that end. Further research into its effectiveness may broaden the use of onplants in future orthodontic cases.

    We study the diffusion of membrane-targeting C2 domains using single-molecule tracking in supported lipid bilayers. The ensemble-averaged mean square displacement (MSD) exhibits superdiffusive behavior. However, the time-averaged MSD of individual trajectories is found to be linear with respect to lag time, as in Brownian diffusion. These observations are explained in terms of bulk excursions that introduce jumps with a heavy-tail distribution. Our experimental results are shown to agree with analytical models of bulk-mediated diffusion and with numerical simulations.

    We study spacetime singularities in a general five-dimensional braneworld with curved branes satisfying four-dimensional maximal symmetry. The bulk is supported by an analog of perfect fluid with the time replaced by the extra coordinate. We show that contrary to the existence of finite-distance singularities from the brane location in any solution with flat (Minkowski) branes, in the case of curved branes there are singularity-free solutions for a range of equations of state compatible with the null energy condition.

    Background There is evidence from North American trials that supported employment using the individual placement and support (IPS) model is effective in helping individuals with severe mental illness gain competitive employment. There have been few trials in other parts of the world. Aims To investigate the effectiveness and cost-effectiveness of IPS in the UK. Method Individuals with severe mental illness in South London were randomised to IPS or local traditional vocational services (treatment as usual) (ISRCTN96677673). Results Two hundred and nineteen participants were randomised, and 90% assessed 1 year later. There were no significant differences between the treatment as usual and intervention groups in obtaining competitive employment (13% in the intervention group and 7% in controls; risk ratio 1.35, 95% CI 0.95–1.93, P = 0.15), nor in secondary outcomes. Conclusions There was no evidence that IPS was of significant benefit in achieving competitive employment for individuals in South London at 1-year follow-up, which may reflect suboptimal implementation. Implementation of IPS can be challenging in the UK context where IPS is not structurally integrated with mental health services, and economic disincentives may lead to lower levels of motivation in individuals with severe mental illness and psychiatric professionals.

    To define aspects of social support that adolescents need from nurses when initiating breastfeeding in the early postpartum. MEDLINE and CINAHL databases for years 2000 to 2009. Three searches were done using the following subject terms: adolescent mothers and breastfeeding (12 studies), adolescent mothers and breastfeeding and support (24 studies), and breastfeeding and adolescent mothers and attitudes (15 studies). The 18 studies that were chosen for this synthesized review illuminated the dimensions of social support identified by House. The four types of supportive behavior categories identified by House were described in these studies (informational, instrumental, emotional, and appraisal). Esteem support as defined by Sarafino seemed to be synonymous with appraisal support. Many studies identified the importance of network support as a fifth category of supportive behavior in increased breastfeeding duration among adolescents; network support was included in this synthesis. These five types of social support provide a framework for defining supportive nurse behaviors. Nurses in the early postpartum can promote the long-term health of adolescents and their children through the social support they offer adolescent mothers as they initiate breastfeeding. Network support appears to be essential to adolescents' breastfeeding experiences and needs to be included with informational, instrumental, emotional, and esteem/appraisal support when investigating support for this population. By integrating the five dimensions of social support into their care, nurses play an essential role in providing adolescents with the positive experiences that are so important to establishing breastfeeding. © 2010 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Little research has examined the characteristics of peer support. Pertinent to such examination may be characteristics such as the distinction between nondirective support (accepting recipients' feelings and cooperative with their plans) and directive (prescribing "correct" choices and feelings). In a peer support program for individuals with diabetes, this study examined (a) whether the distinction between nondirective and directive support was reflected in participants' ratings of support provided by peer supporters and (b) how nondirective and directive support were related to depressive symptoms, diabetes distress, and Hemoglobin A1c (HbA1c). Three hundred fourteen participants with type 2 diabetes provided data on depressive symptoms, diabetes distress, and HbA1c before and after a diabetes management intervention delivered by peer supporters. At post-intervention, participants reported how the support provided by peer supporters was nondirective or directive. Confirmatory factor analysis (CFA), correlation analyses, and structural equation modeling examined the relationships among reports of nondirective and directive support, depressive symptoms, diabetes distress, and measured HbA1c. CFA confirmed the factor structure distinguishing between nondirective and directive support in participants' reports of support delivered by peer supporters. Controlling for demographic factors, baseline clinical values, and site, structural equation models indicated that at post-intervention, participants' reports of nondirective support were significantly associated with lower, while reports of directive support were significantly associated with greater depressive symptoms, altogether (with control variables) accounting for 51% of the variance in depressive symptoms. Peer supporters' nondirective support was associated with lower, but directive support was associated with greater depressive symptoms.

    This article, the tenth in a series of 11, discusses the importance of effective leadership in nursing and how it can enhance the provision of high quality care. Recent findings regarding suboptimal care practices in nursing have demonstrated the need for effective leadership in healthcare settings. Mentors and practice teachers are required to demonstrate leadership as part of their nursing role and their role in facilitating student learning. In addition, mentors and practice teachers are responsible for developing effective leadership skills in students, who will be expected to demonstrate these skills when they become registered nurses or midwives. Guidance for mentors and practice teachers is provided in relation to the eighth domain and outcomes of the Standards to Support Learning and Assessment in Practice on leadership.

  10. Can Galileons support Lorentzian wormholes?

    CERN Document Server

    Rubakov, V A

    2015-01-01

    We discuss the possibility of constructing stable, static, spherically symmetric, asymptotically flat Lorentzian wormhole solutions in General Relativity coupled to a generalized Galileon field $\\pi$. Assuming that Minkowski space-time is obtained at $\\partial \\pi =0$, we find that there is tension between the properties of the energy-momentum tensor required to support a wormhole (violation of average null energy conditions) and stability of the Galileon perturbations about the putative solution (absence of ghosts and gradient instabilities). In 3-dimensional space-time, this tension is strong enough to rule out wormholes with above properties. In higher dimensions, including the most physically interesting case of 4-dimensional space-time, wormholes, if any, must have fairly contrived shapes.

    I am writing in support of Philip Moriarty's article on "The economic-impact fallacy" (June pp16-17). While we all welcome the increases in UK research funding over the last decade, there needs be to a recognition that this was required to compensate for previous chronic underfunding and that, despite what Prime Minister Gordon Brown has called a "knowledge economy", our overall spending still lags significantly behind our competitors. Given the gulf between the rhetoric and the reality, articles by Moriarty and others reflect the sense of disbelief, which most of us feel, that the UK government now also seems to want to limit us all to the kind of shortterm, near-market research that can never hope to give the UK any sustainable lead with respect to (for example) the emerging economies in the Far East.

Atomic force microscopy imaging indicated that these films were also soft with a surface roughness of 2 nm under hydrated conditions. A zwitterionic phospholipid bilayer was then deposited on the polydopamine cushion by fusion of dimyristoylphosphatidylcholine (DMPC and dioleoylphosphatidylcholine (DOPC vesicles. Polydopamine films preserved the lateral mobility of the phospholipids as shown by fluorescence microscopy recovery after photobleaching (FRAP experiments. Diffusion coefficients of ~5.9 and 7.2 µm2 s−1 were respectively determined for DMPC and DOPC at room temperature, values which are characteristic of lipids in a free standing bilayer system.

    Experimental Area Teams have been put in place and charged with the general co-ordination and management of the LHC experimental areas and of the zones in the LHC tunnel hosting near-beam detectors of the experiments. This organization is responsible for the in situ co-ordination of work with the aim of providing a structure that enables the experiment collaborations and accelerator groups to carry out their work effectively and safely. This presentation will review some key elements in the support given to the LHC experimental areas and, given the track record and successful implementation during the LHC installation and commissioning phase, will argue that such an organization structure will be required also for the period of LHC exploitation for physics.

    In this paper we describe the GROTTO visualization projects being carried out at the Naval Research Laboratory. GROTTO is a CAVE-like system, that is, a surround-screen, surround- sound, immersive virtual reality device. We have explored the GROTTO visualization in a variety of scientific areas including oceanography, meteorology, chemistry, biochemistry, computational fluid dynamics and space sciences. Research has emphasized the applications of GROTTO visualization for military, land and sea-based command and control. Examples include the visualization of ocean current models for the simulation and stud of mine drifting and, inside our computational steering project, the effects of electro-magnetic radiation on missile defense satellites. We discuss plans to apply this technology to decision support applications involving the deployment of autonomous vehicles into contaminated battlefield environments, fire fighter control and hostage rescue operations.

  17. Computational Support for Creative Design

    KAUST Repository

    Liu, Han

    2015-12-09

    Supporting user designs of 3D contents remains a challenge in geometric modeling. Various modeling tools have been developed in recent years to facilitate architectural designs and artistic creations. However, these tools require both modeling skills and raw creativity. Instead of creating models from scratch, one of the most popular choices is to extract intrinsic patterns from exemplar inputs (e.g., shape collections and sketches), to produce creative models while preserving the patterns. The mod- eling process contains two main stages, analysis and synthesis. The analysis of input models is usually performed at component level, especially for man-made objects that can be decomposed into several semantic parts, for example, the seat and handles of a bicycle. The synthesis stage recombines parts of shapes to generate new models that usually have topological or geometric variations. In this thesis, we propose three design tools aimed at easing the modeling process. We focus on man-made objects and scenes such as buildings and furniture, as the functionality of such shapes can be analyzed at the component level. A relation graph, which is commonly used in shape analysis, can then be built to represent the input shapes. In our work, the graph nodes denote the elements of a model (i.e., rooms, shape parts, and strokes respectively), while the edges capture the intrinsic relations between connected elements. With the use of graph representations, we extract and present controllable components to users for supporting their designs. The emphasis of our work is on three aspects. Firstly, we propose a framework for supporting interior layout design, which allows users to manipulate the produced floor plans, i.e., changing the scales of rooms and their positions as well. When the user modifies the topology of a layout, the corresponding layout graph is updated and the room geometries are optimized under certain constraints, e.g., user specified scales, the adjacency of

    This paper addresses the problem of practical privacy-preserving machine learning: how to detect patterns in massive, real-world databases of sensitive personal information, while maintaining the privacy of individuals. Chaudhuri and Monteleoni (2008) recently provided privacy-preserving techniques for learning linear separators via regularized logistic regression. With the goal of handling large databases that may not be linearly separable, we provide privacy-preserving support vector machine algorithms. We address general challenges left open by past work, such as how to release a kernel classifier without releasing any of the training data, and how to tune algorithm parameters in a privacy-preserving manner. We provide general, efficient algorithms for linear and nonlinear kernel SVMs, which guarantee $\\epsilon$-differential privacy, a very strong privacy definition due to Dwork et al. (2006). We also provide learning generalization guarantees. Empirical evaluations reveal promising performance on real and...

    Bombardment of periodical arrays formed by Co nanoislands deposited on a Cu(0 0 1) substrate with 1-keV argon ions is simulated by using molecular dynamics. Sputtering yield is analyzed distinguishing between particles sputtered across the supported cluster surface and across the flat substrate surface without nanoparticle above. The dependence of this magnitude on the height and the periodical spacing between nanoislands has been investigated. Results show that this dependence for the sputtering across the nanoislands and across the substrate is different. In the case of the total sputtering, the “substrate” effect prevails since the behavior of this magnitude is approximately analogous to the sputtering across the substrate. The more probable causes are analyzed in this article.

  1. EVALUATING ENVIRONMENTAL DECISION SUPPORT TOOLS.

    Energy Technology Data Exchange (ETDEWEB)

    SULLIVAN, T.

    2004-10-01

    Effective contaminated land management requires a number of decisions addressing a suite of technical, economic, and social concerns. These concerns include human health risks, ecological risks, economic costs, technical feasibility of proposed remedial actions, and the value society places on clean-up and re-use of formerly contaminated lands. Decision making, in the face of uncertainty and multiple and often conflicting objectives, is a vital and challenging role in environmental management that affects a significant economic activity. Although each environmental remediation problem is unique and requires a site-specific analysis, many of the key decisions are similar in structure. This has led many to attempt to develop standard approaches. As part of the standardization process, attempts have been made to codify specialist expertise into decision support tools. This activity is intended to facilitate reproducible and transparent decision making. The process of codifying procedures has also been found to be a useful activity for establishing and rationalizing management processes. This study will have two primary objectives. The first is to develop taxonomy for Decision Support Tools (DST) to provide a framework for understanding the different tools and what they are designed to address in the context of environmental remediation problems. The taxonomy will have a series of subject areas for the DST. From these subjects, a few key areas will be selected for further study and software in these areas will be identified. The second objective, will be to review the existing DST in the selected areas and develop a screening matrix for each software product.

    Social support benefits health and well-being in older individuals, however the mechanism remains poorly understood. One proposal, the stress-buffering hypothesis states social support 'buffers' the effects of stress on health. Alternatively, the main effect hypothesis suggests social support independently promotes health. We examined the combined association of social support and stress on the aging brain. Forty healthy older adults completed stress questionnaires, a social network interview and structural MRI to investigate the amygdala-medial prefrontal cortex circuitry, which is implicated in social and emotional processing and negatively affected by stress. Social support was positively correlated with right medial prefrontal cortical thickness while amygdala volume was negatively associated with social support and positively related to stress. We examined whether the association between social support and amygdala volume varied across stress level. Stress and social support uniquely contribute to amygdala volume, which is consistent with the health benefits of social support being independent of stress.

    Full Text Available Background: Parks are important venues that can encourage population-level physical activity, and policy legislation can facilitate or discourage physical activity and other park uses, depending on the type and level of support. This study aims to summarize the status and content of state-level park-related legislation. Methods: We searched for eligible legislation from 2001–2007 in two data sources, CDC’s Nutrition, Physical Activity and Obesity Legislative Database and Lexis-Nexis, using the key words conservation, growth management/land use, parks, recreation, preservation, path, green space, or open space. State legislation was categorized into seven broad topic areas and analyzed by number introduced and passed (enacted as law, by state and category. Results: States varied in the number and type of park-related legislation introduced and passed. Common categories of introduced park-related state legislation were preservation or conservation (n = 26, 9 passed, funding (n = 43, 10 passed, creation or acquisition of park land (n = 53, 9 passed, safety and liability (n = 34, 5 passed, accessibility (n = 20, 2 passed, outreach (n = 15, 2 passed, and outdoor activities (n = 13, 2 passed. Conclusion: During 2001 to 2007, 19% of park-related state legislation was enacted. Research on legislative policy is an emerging field, and more information on the content of park-related legislation could assist states in their efforts to promote physical activity in park venues.

    2012-08-01

    Full Text Available Tracking occluded objects at different depths has become as extremely important component of study for any video sequence having wide applications in object tracking, scene recognition, coding, editing the videos and mosaicking. The paper studies the ability of annotation to track the occluded object based on pyramids with variation in depth further establishing a threshold at which the ability of the system to track the occluded object fails. Image annotation is applied on 3 similar video sequences varying in depth. In the experiment, one bike occludes the other at a depth of 60cm, 80cm and 100cm respectively. Another experiment is performed on tracking humans with similar depth to authenticate the results. The paper also computes the frame by frame error incurred by the system, supported by detailed simulations. This system can be effectively used to analyze the error in motion tracking and further correcting the error leading to flawless tracking. This can be of great interest to computer scientists while designing surveillance systems etc.

    This report describes the second year of research effort under the grant Research Supporting Satellite Communications Technology. The research program consists of two major projects: Fault Tolerant Link Establishment and the design of an Auto-Configurable Receiver. The Fault Tolerant Link Establishment protocol is being developed to assist the designers of satellite clusters to manage the inter-satellite communications. During this second year, the basic protocol design was validated with an extensive testing program. After this testing was completed, a channel error model was added to the protocol to permit the effects of channel errors to be measured. This error generation was used to test the effects of channel errors on Heartbeat and Token message passing. The C-language source code for the protocol modules was delivered to Goddard Space Flight Center for integration with the GSFC testbed. The need for a receiver autoconfiguration capability arises when a satellite-to-ground transmission is interrupted due to an unexpected event, the satellite transponder may reset to an unknown state and begin transmitting in a new mode. During Year 2, we completed testing of these algorithms when noise-induced bit errors were introduced. We also developed and tested an algorithm for estimating the data rate, assuming an NRZ-formatted signal corrupted with additive white Gaussian noise, and we took initial steps in integrating both algorithms into the SDR test bed at GSFC.

  8. Xenon Gamma Detector Project Support

    Energy Technology Data Exchange (ETDEWEB)

    This project provided funding of $48,500 for part of one year to support the development of compressed xenon spectrometers at BNL. This report describes upgrades that were made to the existing detector system electronics during that period, as well as subsequent testing with check sources and Special Nuclear Materials. Previous testing of the equipment extended only up to the energy of 1.3 MeV, and did not include a spectrum of Pu-239. The new electronics allowed one-button activation of the high voltage ramp that was previously controlled by manual adjustments. Mechanical relays of the charging circuit were replaced by a tera-ohm resistor chain and an optical switch. The preamplifier and shaping amplifier were replaced by more modern custom designs. We found that the xenon purity had not been degraded since the chamber was filled 10 years earlier. The resulting spectra showed significantly better resolution than sodium iodide spectra, and could be analyzed quite effectively by methods using peak area templates.

    Full Text Available The article discusses the possibilities and the problematic issues of the information support of anti-terrorist activities. Among the main measures are called: PRsupport of speeches by leaders and officials of the state executive authorities, prosecutors, law enforcement agencies in the media; countering terrorism and extremism in the information space; press conferences, round tables and conferences on anti-terrorist and antiextremist topics; utilization of social advertising; monitoring of Internet resources to the development of the social networks of anti-terrorist direction.Terrorism can not be regarded as a problem of a single country. International and domestic experience in combating these phenomena indicates failure only of force feedback, which at any stage of the problem only to show the ability of temporal localization of specific threats and prevent individual acts of terrorism without affecting the situation as a whole.Terrorist offenses, is widespread in modern society is a complex system of balances is included in the set of complementary processes. These processes are not only, as is commonly believed, criminal and economic background, although any even minor manifestations of a terrorist nature no doubt be regarded as an attack on the security of society and the state.

    Brandes, Ulrik; Cornelsen, Sabine; Pampel, Barbara; Sallaberry, Arnaud

    A path-based support of a hypergraph H is a graph with the same vertex set as H in which each hyperedge induces a Hamiltonian subgraph. While it is NP-complete to compute a path-based support with the minimum number of edges or to decide whether there is a planar path-based support, we show that a path-based tree support can be computed in polynomial time if it exists.

  19. Keratometry device for surgical support

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available Abstract Background High astigmatisms are usually induced during corneal suturing subsequent to tissue transplantation or any other surgery which involves corneal suturing. One of the reasons is that the procedure is intimately dependent on the surgeon's skill for suturing identical stitches. In order to evaluate the influence of the irregularity on suturing for the residual astigmatism, a prototype for ophthalmic surgical support has been developed. The final intention of this prototype is to be an evaluation tool for guided suture and as an outcome diminish the postoperative astigmatism. Methods The system consists of hand held ring with 36 infrared LEDs, that is to be projected onto the lachrymal film of the cornea. The image is reflected back through the optics of the ocular microscope and its distortion from the original circular shape is evaluated by developed software. It provides keratometric and circularity measurements during surgery in order to guide the surgeon for uniformity in suturing. Results The system is able to provide up to 23D of astigmatism (32D - 55D range and is ± 0.25D accurate. It has been tested in 14 volunteer patients intraoperative and has been compared to a commercial keratometer Nidek Oculus Hand-held corneal topographer. The correlation factors are 0.92 for the astigmatism and 0.97 for the associated axis. Conclusion The system is potentially efficient for guiding the surgeon on uniformity of suturing, presenting preliminary data indicating an important decrease on the residual astigmatism, from an average of 8D - for patients not submitted to the prototype guidance - to 1.4D - for patients who have actually been submitted to the prototype guidance - after the first 24 hours post-surgery and in the subsequent weeks. It also indicates that the surgeon should achieve circularity greater or equal to 98% in order to avoid postoperative astigmatisms over 1D.

    2002-03-31

    This project has three main goals: Thin Films Studies, Preparation of Graded Porous Substrates and Basic Electrical Characterization and testing of Planar Single Cells. This period has continued to address the problem of making dense 1/2 to 5 {micro}m thick dense layers on porous substrates (the cathode LSM). Our current status is that we are making structures of 2-5 cm{sup 2} in area, which consist of either dense YSZ or CGO infiltrated into a 2-5 {micro}m thick 50% porous layer made of either nanoncrystalline CGO or YSZ powder. This composite structure coats a macroporous cathode or anode; which serves as the structural element of the bi-layer structure. These structures are being tested as SOFC elements. A number of structures have been evaluated both as symmetrical and as button cell configuration. Results of this testing indicates that the cathodes contribute the most to cell losses for temperatures below 750 C. In this investigation different cathode materials were studied using impedance spectroscopy of symmetric cells and IV characteristics of anode supported fuel cells. Cathode materials studied included La{sub 0.8}Sr{sub 0.2}Co{sub 0.2}Fe{sub 0.8}O{sub 3} (LSCF), La{sub 0.7}Sr{sub 0.2}MnO{sub 3} (LSM), Pr{sub 0.8}Sr{sub 0.2}Fe{sub 0.8}O{sub 3} (PSCF), Sm{sub 0.8}Sr{sub 0.2}Co{sub 0.2}Fe{sub 0.8}O{sub 3} (SSCF), and Yb{sub .8}Sr{sub 0.2}Co{sub 0.2}Fe{sub 0.8}O{sub 3} (SSCF). A new technique for filtering the Fourier transform of impedance data was used to increase the sensitivity of impedance analysis. By creating a filter specifically for impedance spectroscopy the resolution was increased. The filter was tailored to look for specific circuit elements like R//C, Warburg, or constant phase elements. As many as four peaks can be resolved using the filtering technique on symmetric cells. It may be possible to relate the different peaks to material parameters, like the oxygen exchange coefficient. The cathode grouped in order from lowest to highest ASR is

    The design of a decision support system for capacity planning in clinical laboratories is discussed. The DSS supports decisions concerning the following questions: how should the laboratory be divided into job shops (departments/sections), how should staff be assigned to workstations and how should samples be assigned to workstations for testing. The decision support system contains modules for supporting decisions at the overall laboratory level (concerning the division of the laboratory into job shops) and for supporting decisions at the job shop level (assignment of staff to workstations and sample scheduling). Experiments with these modules are described showing both the functionality and the validity.

    The engagement of JRC IPTS in the GTAP contributing team to the EU domestic support has opened up the opportunity to use the CATS database when compiling EU domestic support payments by member state, which are subsequently calibrated into the GTAP database. To maintain consistency, the GTAP version...... 9 includes EU domestic support which follows the approach adopted in the previous releases (Jensen, 2009, 2010). The difference is for pillar 1 support for which the CATS data are used (in previous GTAP database releases, pillar 1 support was based on EAGF financial reports). All together EU...... domestic support amounts to 66,530 million euros in 2011 (i.e. pillar 1 expenditures from CATS, pillar 2 and national expenditures from Producer Support Estimate (PSE) by OECD). In addition, minor improvements to the allocation of payments have been proposed for the version 9 release. On the other hand...
