The propagation of light in foams creates patterns which are generated due to the reflection and refraction of light. One of these patterns is observed by the formation of multiple mirror images inside liquid bridges in a layer of bubbles in a Hele-Shaw cell. We are presenting the existence of these patterns in foams and their relation with hyperbolic geometry and Sierpinski gaskets using the Poincare disk model. The images obtained from the experiment in foams are compared to the case of hyperbolic optical elements. -- Highlights: → The chaotic scattering of light in foams generating deltoid patterns is based on hyperbolic geometry. → The deltoid patterns are obtained through the Plateau borders in a Hele-Shaw cell. → The Plateau borders act like hyperbolic prism. → Some effects of the refraction and reflection of the light rays were studied using a hyperbolic prism.

Bradford, Kathryn; Abrahams, Leslie; Hegglin, Miriam; Klima, Kelly

2015-10-06

With increasing evidence of global warming, many cities have focused attention on response plans to address their populations' vulnerabilities. Despite expected increased frequency and intensity of heat waves, the health impacts of such events in urban areas can be minimized with careful policy and economic investments. We focus on Pittsburgh, Pennsylvania and ask two questions. First, what are the top factors contributing to heat vulnerability and how do these characteristics manifest geospatially throughout Pittsburgh? Second, assuming the City wishes to deploy additional cooling centers, what placement will optimally address the vulnerability of the at risk populations? We use national census data, ArcGIS geospatial modeling, and statistical analysis to determine a range of heat vulnerability indices and optimal cooling center placement. We find that while different studies use different data and statistical calculations, all methods tested locate additional cooling centers at the confluence of the three rivers (Downtown), the northeast side of Pittsburgh (Shadyside/Highland Park), and the southeast side of Pittsburgh (Squirrel Hill). This suggests that for Pittsburgh, a researcher could apply the same factor analysis procedure to compare data sets for different locations and times; factor analyses for heat vulnerability are more robust than previously thought.

Preparing for Local Adaptation: Understanding Flood Risk Perceptions in Pittsburgh

Science.gov (United States)

Klima, K.; Wong-Parodi, G.

2015-12-01

The City of Pittsburgh experiences numerous floods every year. Aging and insufficient infrastructure contribute to flash floods and to over 20 billion gallons of combined sewer overflows annually, contaminating Pittsburgh's streets, basements, and waterways. Climate change is expected to further exacerbate this problem by causing more intense and more frequent extreme precipitation events in Western Pennsylvania. For a stormwater adaptation plan to be implemented effectively, the City will need informed public support. One way to achieve public understanding and support is through effective communication of the risks, benefits, and uncertainties of local flooding hazards and adaptation methods. In order to develop these communications effectively, the city and its partners will need to know what knowledge and attitudes the residents of Pittsburgh already hold about flood risks. Here we seek to (1) identify Pittsburgh residents' knowledge level, risk perception and attitudes towards flooding and storm water management, and (2) pre-test communications meant to inform and empower Pittsburghers about flood risks and adaptation strategies. We conduct a city-wide survey of 10,000 Pittsburgh renters and homeowners from four life situations: high risk, above poverty; high-risk, below poverty; low risk, above poverty; and low-risk, below poverty. Mixed media recruitment strategies (online and paper-based solicitations guided/organized by community organizations) assist in reaching all subpopulations. Preliminary results suggest participants know what stormwater runoff is, but have a weak understanding of how stormwater interacts with natural and built systems. Furthermore, although participants have a good understanding of the difference between green and gray infrastructure, this does not translate into a change in their willingness to pay for green infrastructure adaptation. This suggests additional communications about flood risks and adaptation strategies.

Robert R. Shaw, MD: thoracic surgical hero, Afghanistan medical pioneer, champion for the patient, never a surgical society president.

Urschel, Harold C; Urschel, Betsey Bradley

2012-06-01

Dr Robert R. Shaw arrived in Dallas to practice Thoracic Surgery in 1937, as John Alexander's 7th Thoracic Surgical Resident from Michigan University Medical Center. Dr Shaw's modus operandi was, "You can accomplish almost anything, if you don't care who gets the credit." He was a remarkable individual who cared the most about the patient and very little about getting credit for himself. From 1937 to 1970, Dr Shaw established one of the largest lung cancer surgical centers in the world in Dallas, Texas. It was larger than M.D. Anderson and Memorial Sloan-Kettering Hospitals put together regarding the surgical treatment of lung cancer patients. To accomplish this, he had the help of Dr Donald L. Paulson, who trained at the Mayo Clinic and served as Chief of Thoracic Surgery at Brook Army Hospital during the Second World War. Following the War, because of his love for Texas, he ended up as a partner of Dr Shaw in Dallas. Together, they pursued the development of this very large surgical lung cancer center. Dr Shaw and his wife Ruth went to Afghanistan with Medico multiple times to teach men modern cardiac and thoracic surgery. They also served as consultants on Medico's Ship of Hope in Africa. Dr Shaw initiated multiple new operations including: 1) resection of Pancoast's cancer of the lung after preoperative irradiation; 2) upper lobe of the lung bronchoplasty, reattaching (and saving) the lower lobe to prevent the "disabling" pneumonectomy; and 3) resections of pulmonary mucoid impaction of the lung in asthmatics. Because of his humility and giving "the credit to others," Dr Shaw was never President of a major medical or surgical association. Copyright © 2012 The Society of Thoracic Surgeons.

Life support and euthanasia, a perspective on Shaw's new perspective.

Science.gov (United States)

Busch, Jacob; Rodogno, Raffaele

2011-02-01

It has recently been suggested by Shaw (2007) that the distinction between voluntary active euthanasia, such as giving a patient a lethal overdose with the intention of ending that patient's life, and voluntary passive euthanasia, such as removing a patient from a ventilator, is much less obvious than is commonly acknowledged in the literature. This is argued by suggesting a new perspective that more accurately reflects the moral features of end-of-life situations. The argument is simply that if we consider the body of a mentally competent patient who wants to die, a kind of 'unwarranted' life support, then the distinction collapses. We argue that all Shaw has provided is a perspective that makes the conclusion that there is little distinction between voluntary active euthanasia and voluntary passive euthanasia only seemingly more palatable. In doing so he has yet to convince us that this perspective is superior to other perspectives and thus more accurately reflects the moral features of the situations pertaining to this issue.

His work in hydrodynamics (the Hele-Shaw cell and Hele-Shaw pump and his important contribution to the successful development of high-speed aircraft (his variable pitch airscrew, continues to be relevant today. In 1922, as President of the Institution of Mechanical Engineers, he introduced the National Certificate scheme in Britain. It is not well known that Hele-Shaw spent two years in South Africa (1904–1905 attached to the Transvaal Technical Institute, a forerunner of the University of the Witwatersrand. One of only three Fellows of the Royal Society of London in southern Africa in 1905, he was a founder Council member of the Royal Society of South Africa and one of the hosts of the 1905 visit to southern Africa by the British Association for the Advancement of Science. The purpose of this paper is to highlight the time he spent in South Africa and to contextualise it within the larger perspective of his engineering career.

On a Hele-Shaw flow with a time-dependent gap in the presence of surface tension

International Nuclear Information System (INIS)

Savina, T V; Nepomnyashchy, A A

2015-01-01

The introduction of surface tension into a Hele-Shaw problem makes it more realistic from the physical viewpoint, but more difficult from the mathematical viewpoint. In this paper we discuss a Hele-Shaw flow with a time-dependent gap taking into account the surface tension of the free boundary. We use the Schwarz function method to find asymptotic solutions for the interior problem in the case when the initial shape of the droplet is a weakly distorted circle. (paper)

Determining the number of fingers in the lifting Hele-Shaw problem

Science.gov (United States)

Miranda, Jose; Dias, Eduardo

2013-11-01

The lifting Hele-Shaw cell flow is a variation of the celebrated radial viscous fingering problem for which the upper cell plate is lifted uniformly at a specified rate. This procedure causes the formation of intricate interfacial patterns. Most theoretical studies determine the total number of emerging fingers by maximizing the linear growth rate, but this generates discrepancies between theory and experiments. In this work, we tackle the number of fingers selection problem in the lifting Hele-Shaw cell by employing the recently proposed maximum-amplitude criterion. Our linear stability analysis accounts for the action of capillary, viscous normal stresses, and wetting effects, as well as the cell confinement. The comparison of our results with very precise laboratory measurements for the total number of fingers shows a significantly improved agreement between theoretical predictions and experimental data.

The ethics of killing human/great-ape chimeras for their organs: a reply to Shaw et al.

Science.gov (United States)

Palacios-González, César

2016-06-01

The aim of this paper is to critically examine David Shaw, Wybo Dondorp, and Guido de Wert's arguments in favour of the procurement of human organs from human/nonhuman-primate chimeras, specifically from great-ape/human chimeras. My main claim is that their arguments fail and are in need of substantial revision. To prove this I first introduce the topic, and then reconstruct Shaw et al.'s position and arguments. Next, I show that Shaw et al.: (1) failed to properly apply the subsidiarity and proportionality principles; (2) neglected species overlapping cases in their ethical assessment; (3) ignored the ethics literature on borderline persons; and (4) misunderstood McMahan's two-tiered moral theory. These mistakes render an important part of their conclusions either false or problematic to the point that they would no longer endorse them. Finally I will briefly mention a possible multipolar solution to the human organ shortage problem that would reduce the need for chimeras' organs.

Smoky ol' town: the significance of Pittsburgh in U.S. air pollution history

Energy Technology Data Exchange (ETDEWEB)

James Longhurst [Muskingum College, New Concord, OH (United States)

2007-06-15

Pittsburgh came to be - and came to be dirtybecause of location, location, and location. Two navigable rivers met in the middle of a forest, and combined to form a third river. This was an irresistible meeting point for settlement, trade, and industry. It was an added bonus that this meeting point was at the center of the 'Pittsburgh seam' of coal. While the natural advantages of geography and geology initiated development, Pittsburgh's growth soon attracted man-made transportation networks to import resources from its hinterland and spread finished materials through the Midwest. As the city boomed into an industrial metropolis - the Iron City, the Steel City - through the late 19th and early 20th centuries, the smoke only became worse, and Pittsburgh became known, nationally and even internationally, for its dirt, grime, and filth. For many of the city's workers and businessmen, smoke was a sign of progress and economic success. From small-scale iron production, to the process of refining coal into 'coke,' to the Bessemer steel process, to J.P. Morgan and Andrew Carnegie's creation of the vertically-integrated U.S. Steel corporation, to the pioneering use of 'byproduct' coke ovens, Pittsburgh was home to successive technologies for transforming raw materials into finished or refined goods. Pittsburgh is both singular and representative; its story is at the forefront of pollution history, but the forces, trends, and events the city witnessed were the same in many cities across the nation. So while it is true that A&WMA's headquarters are in Pittsburgh for a reason, it is also true that its membership is spread across the nation and the world. That membership will most likely find something in these four themes from Pittsburgh's history that is representative of their own study. 7 refs., 3 photos.

International audience; The response of the free liquid surface in a Hele-Shaw cell subjected to a horizontal oscillation is investigated. We study the low-oscillation-amplitude regime and we show, by varying the fluid viscosity, ν, and the forcing frequency, ω, that the ratio between the Stokes viscous length, 2ν/ω, and the cell thickness greatly affects the amplitude and phase lag of the gravity waves. In particular, the sloshing system undergoes an under-damped/overdamped transition for su...

New archeointensity results from the reconstructed ancient kiln by the Tsunakawa-Shaw method

Science.gov (United States)

Yamamoto, Y.; Hatakeyama, T.; Kitahara, Y.; Saito, T.

2017-12-01

Yamamoto et al. (2015) reported that baked clay samples from the floor of a reconstructed ancient kiln provided a reliable Tsunakawa-Shaw (LTD-DHT Shaw) archeointensity (AI) estimate of 47.3 +/- 2.2 microT which is fairly consistent with the in situ geomagnetic field of 46.4 microT at the time of the reconstruction. The reconstruction was conducted to reproduce an excavated kiln of the seventh century in Japan and Sue-type potteries of contemporary style were also fired (Nakajima et al., 1974). Two of the potteries with reddish color were recently subjected to the Tsunakawa-Shaw archeointensity determinations, resulting in reliable AI estimates of 45.4 +/- 2.3 (N=6) and 48.2 +/- 2.7 microT (N=15) when specimens were heated in air in laboratory (Yamamoto et al., 2017 JpGU-AGU Joint Meeting). We have had another opportunity to take samples from a new reconstructed ancient kiln in Japan which was fired in autumn 2016. The samples were two Sue-type potteries with grayish color (bowl-type and plate-type) and some blocks collected from inner wall of the kiln body. They were cut into mini specimens and then subjected to the Tsunakawa-Shaw experiment. Heating in laboratory was done either in air or vacuum.For the bowl-type pottery, AIs of 46.9 +/- 2.8 (N=6, air) and 45.3 +/- 2.3 microT (N=6, vacuum) are obtained. They are indistinguishable each other and consistent with the IGRF field of 47.4 microT at the reconstructed location in 2016. For the plate-type pottery, AIs result in 41.8 +/- 1.3 (N=4, air) and 43.9 +/- 3.9 microT (N=4, vacuum). They are also indistinguishable each other but the former AI is slightly lower than the IGRF field.For the inner wall, AIs of 45.0 (N=1, air) and 46.8 microT (N=1, vacuum) are obtained from a right-side wall, and those of 45.5 +/- 2.5 (N=2, air) and 47.7 +/- 3.0 microT (N=2, vacuum) are observed from a left-side wall. They are all indistinguishable and consistent with the IGRF field.

Faraday waves in a Hele-Shaw cell

Science.gov (United States)

Li, Jing; Li, Xiaochen; Chen, Kaijie; Xie, Bin; Liao, Shijun

2018-04-01

We investigate Faraday waves in a Hele-Shaw cell via experimental, numerical, and theoretical studies. Inspired by the Kelvin-Helmholtz-Darcy theory, we develop the gap-averaged Navier-Stokes equations and end up with the stable standing waves with half frequency of the external forced vibration. To overcome the dependency of a numerical model on the experimental parameter of wave length, we take two-phase flow into consideration and a novel dispersion relation is derived. The numerical results compare well with our experimental data, which effectively validates our proposed mathematical model. Therefore, this model can produce robust solutions of Faraday wave patterns and resolve related physical phenomena, which demonstrates the practical importance of the present study.

Gas driven displacement in a Hele-Shaw cell with chemical reaction

Science.gov (United States)

White, Andrew; Ward, Thomas

2011-11-01

Injecting a less viscous fluid into a more viscous fluid produces instabilities in the form of fingering which grow radially from the less viscous injection point (Saffman & Taylor, Proc. R. Soc. Lon. A, 1958). For two non-reacting fluids in a radial Hele-Shaw cell the ability of the gas phase to penetrate the liquid phase is largely dependent on the gap height, liquid viscosity and gas pressure. In contrast combining two reactive fluids such as aqueous calcium hydroxide and carbon dioxide, which form a precipitate, presents a more complex but technically relevant system. As the two species react calcium carbonate precipitates and increases the aqueous phase visocosity. This change in viscosity may have a significant impact on how the gas phase penetrates the liquid phase. Experimental are performed in a radial Hele-Shaw cell with gap heights O(10-100) microns by loading a single drop of aqueous calcium hydroxide and injecting carbon dioxide into the drop. The calcium hydroxide concentration, carbon dioxide pressure and gap height are varied and images of the gas penetration are analyzed to determine residual film thickness and bursting times.

Preparing for local adaptation: Understanding flood risk perceptions in Pittsburgh

Science.gov (United States)

Wong-Parodi, G.; Klima, K.

2016-12-01

In cities such as Pittsburgh, aging and insufficient infrastructure contributes to flashfloods and numerous combined sewer overflows annually, contaminating streets, basements and waterways. Climate change is expected to further exacerbate this problem by causing more intense and more frequent extreme events in Western Pennsylvania. For a storm water adaptation plan to be implemented successfully, the City of Pittsburgh will need informed public support. One way to achieve public understanding and support is through effective communication of the risks, benefits, and uncertainties of local flooding hazards and adaptation methods. In order to develop risk communications effectively, the City and its partners will need to know what knowledge and attitudes the residents of Pittsburgh already hold about flood risks. To that end we surveyed 1,376 Pittsburgh residents on a variety of flood risk topics through an online or paper survey in Fall 2015. On balance, residents were relatively knowledgeable about storm water and see the City's current infrastructure as being inadequate to meet future risk. Moreover, they see the risk of runoff events as increasing and especially among those who live in hazardous flood areas. Residents expressed interest in having a dedicated fund to deal with runoff events. Among those queried about their willingness-to-pay, those asked to pay $15 were most interested in a dedicated fund and for green infrastructure (as opposed to gray infrastructure) in particular. Finally, while most residents favored green infrastructure in terms of its attractiveness and perceived affects on mitigating climate change many did not see it as effective at addressing flooding as gray infrastructure. We found people understand the risk and are open to doing something about it. However, more guidance and information on appropriate ways to adapt locally in terms that make sense to residents could enhance informed support for adaptation measures.

Mixing foams and grains in Hele-Shaw cells

Energy Technology Data Exchange (ETDEWEB)

Tufaile, A P B; Tufaile, A; Haddad, T A S, E-mail: tufaile@usp.b [Escola de Artes, Ciencias e Humanidades da Universidade de Sao Paulo, R. Arlindo Bettio, 1000, 03828-000, Sao Paulo (Brazil)

2010-09-01

We have observed some features of the coexistence of foams and granular materials in Hele-Shaw cells. The most part of the liquid and granular material stays at the bottom of the cell, with only a small quantity of the mixture resting on the froth. The fractal dimensions of the final states of the foams are close to the values obtained from the Random Apollonian Packing model. The disperse structure of the granular material affects the probability distribution of number of sides of the foam bubbles. The nearest neighbor distances between the peaks of the sand piles at the bottom of the cell are close to a lognormal distribution.

Contracting bubbles in Hele-Shaw cells with a power-law fluid

International Nuclear Information System (INIS)

McCue, Scott W; King, John R

2011-01-01

The problem of bubble contraction in a Hele-Shaw cell is studied for the case in which the surrounding fluid is of power-law type. A small perturbation of the radially symmetric problem is first considered, focussing on the behaviour just before the bubble vanishes, it being found that for shear-thinning fluids the radially symmetric solution is stable, while for shear-thickening fluids the aspect ratio of the bubble boundary increases. The borderline (Newtonian) case considered previously is neutrally stable, the bubble boundary becoming elliptic in shape with the eccentricity of the ellipse depending on the initial data. Further light is shed on the bubble contraction problem by considering a long thin Hele-Shaw cell: for early times the leading-order behaviour is one-dimensional in this limit; however, as the bubble contracts its evolution is ultimately determined by the solution of a Wiener–Hopf problem, the transition between the long thin limit and the extinction limit in which the bubble vanishes being described by what is in effect a similarity solution of the second kind. This same solution describes the generic (slit-like) extinction behaviour for shear-thickening fluids, the interface profiles that generalize the ellipses that characterize the Newtonian case being constructed by the Wiener–Hopf calculation

Stonehenge is a site that continues to yield surprises. Excavation in 2009 added a new and unexpected feature: a smaller, dismantled stone circle on the banks of the River Avon, connected to Stonehenge itself by the Avenue. This new structure has been labelled 'Bluestonehenge' from the evidence that it once held a circle of bluestones that were later removed to Stonehenge. Investigation of the Avenue closer to Stonehenge revealed deep periglacial fissures within it. Their alignment on Stonehe...

Full Text Available We study the time evolution of the free boundary of a viscous fluid for planar flows in Hele-Shaw cells under injection. Applying methods from the theory of univalent functions, we prove the invariance in time of Φ-likeness property (a geometric property which includes starlikeness and spiral-likeness for two basic cases: the inner problem and the outer problem. We study both zero and nonzero surface tension models. Certain particular cases are also presented.

Investigation and visualization of liquid–liquid flow in a vertically mounted Hele-Shaw cell: flow regimes, velocity and shape of droplets

International Nuclear Information System (INIS)

Shad, S; Gates, I D; Maini, B B

2009-01-01

The motion and shape of a liquid drop flowing within a continuous, conveying liquid phase in a vertical Hele-Shaw cell were investigated experimentally. The continuous phase was more viscous and wetted the bounding walls of the Hele-Shaw cell. The gap between the Hele-Shaw plates was set equal to 0.0226 cm. Four different flow regimes were observed: (a) small-droplet flow, (b) elongated-droplet flow, (c) churn flow and (d) channel flow. At low capillary number, that is, when capillary forces are larger than viscous forces, the droplet shape was irregular and changed with time and distance, and it moved with lower velocity than that of the conveying phase. At higher capillary number, several different shapes of stabilized elongated and flattened drops were observed. In contrast to gas–liquid systems, the velocities of droplets are higher than that of conveying liquid. New correlations derived from dimensionless analysis and fitted to the experimental data were generated to predict the elongated-drop velocity and aspect ratio

Hadi Saroso

2014-12-01

Full Text Available Coconut oil combustion characteristic is observed experimentally by evaporating oil in the boiler then mix it with air before being burned at various equivalence ratios in the Hele-shaw cell. The result shows that, coconut oil tends to break into glycerol and fatty acid due to hydrolysis reaction producing the flame propagation, where the fatty acid flame propagates first then glycerol flame. Micro-explosion occurs when moisture from fatty acid combustion is absorbed by glycerol and higher heating due to higher flame speed produces more micro-explosion.

Non-Newtonian Hele-Shaw Flow and the Saffman-Taylor Instability

Kondic, L.; Shelley, M.J.; Palffy-Muhoray, P.

1998-01-01

We explore the Saffman-Taylor instability of a gas bubble expanding into a shear thinning liquid in a radial Hele-Shaw cell. Using Darcy close-quote s law generalized for non-Newtonian fluids, we perform simulations of the full dynamical problem. The simulations show that shear thinning significantly influences the developing interfacial patterns. Shear thinning can suppress tip splitting, and produce fingers which oscillate during growth and shed side branches. Emergent length scales show reasonable agreement with a general linear stability analysis. copyright 1998 The American Physical Society

Paleomagnetic intensity of Aso pyroclastic flows: Additional results with LTD-DHT Shaw method, Thellier method with pTRM-tail check

Science.gov (United States)

Maruuchi, T.; Shibuya, H.

2009-12-01

For the sake to calibrate the absolute value of the ’relative paleointensity variation curve’ drawn from sediment cores, Takai et al. (2002) proposed to use pyroclastic flows co-bearing with wide spread tephras. The pyroclastic flows prepare volcanic rocks with TRM, which let us determine absolute paleointensity, and the tephras prepare the correlation with sediment stratigraphy. While 4 out of 6 pyroclastic flows are consistent with Sint-800 paleointensity variation curve, two flows, Aso-2 and Aso-4, show weaker and stronger than Sint-800 beyond the error, respectively. We revisited the paleointensity study of Aso pyroclastic flows, adding LTD- DHT Shaw method, the pTRM-tail check in Thellier experiment, and LTD-DHT Shaw method by using volcanic glasses. We prepared 11 specimens from 3 sites of Aso-1 welded tuff for LTD-DHT Shaw method experiments, and obtained 6 paleointensities satisfied a set of strict criteria. They yield an average paleointensity of 21.3±5.8uT, which is smaller than 31.0±3.4uT provided by Takai et al. (2002). For Aso-2 welded tuff, 11 samples from 3 sites were submitted to Thellier experiments, and 6 passed a set of pretty stringent criteria including pTRM-tail check, which is not performed by Takai et al. (2002). They give an average paleointensity of 20.2±1.5uT, which is virtually identical to 20.2±1.0uT (27 samples) given by Takai et al. (2002). Although the success rate was not good in LTD-DHT Shaw method, 2 out of 12 specimens passed the criteria, and gave 25.8±3.4uT, which is consistent with Takai et al. (2002). In addition, we obtained a reliable paleointensity from a volcanic glass in LTD-DHT Shaw method, it gives a paleointensity of 23.6 uT. It is also consitent with Takai et al. (2002). For Aso-3 welded tuff, we performed only LTD-DHT Shaw method for one specimen from one site yet. It gives a paleointensity of 43.0uT, which is higher than 31.8±3.6uT given by Takai et al. (2002). Eight sites were set for Aso-4 welded tuff

This paper presents new solutions for any finite number of bubbles steadily translating along a Hele–Shaw channel. This constitutes a nonlinear free boundary problem. The solutions can be written down explicitly in terms of a special transcendental function called the Schottky–Klein prime function. This work generalizes the exact solutions for a single bubble in a channel found by Tanveer (1987 Phys. Fluids 30 651–8) as well as the solutions for streams of bubbles aligned along the channel centreline due to Vasconcelos (1994 Phys. Rev. E 50 R3306–9)

The U.S. Geological Survey recently completed a digital coal resource assessment model of the Upper Pennsylvanian Pittsburgh coal bed, which indicates that after subtracting minedout coal, 16 billion short tons (14 billion tonnes) remain of the original 34 billion short tons (31 billion tonnes) of coal. When technical, environmental, and social restrictions are applied to the remaining Pittsburgh coal model, only 12 billion short tons (11 billion tonnes) are available for mining. Our assessment models estimate that up to 0.61 billion short tons (0.55 billion tonnes), 2.7 billion short tons (2.4 billion tonnes), and 8.5 billion short tons (7.7 billion tonnes) could be available for surface mining, continuous mining, and longwall mining, respectively. This analysis is an example of a second-generation regional coal availability study designed to model recoverability characteristics for all the major coal beds in the United States. ?? 2001 International Association for Mathematical Geology.

Bubble extinction in Hele-Shaw flow with surface tension and kinetic undercooling regularization

International Nuclear Information System (INIS)

Dallaston, Michael C; McCue, Scott W

2013-01-01

We perform an analytic and numerical study of an inviscid contracting bubble in a two-dimensional Hele-Shaw cell, where the effects of both surface tension and kinetic undercooling on the moving bubble boundary are not neglected. In contrast to expanding bubbles, in which both boundary effects regularize the ill-posedness arising from the viscous (Saffman–Taylor) instability, we show that in contracting bubbles the two boundary effects are in competition, with surface tension stabilizing the boundary, and kinetic undercooling destabilizing it. This competition leads to interesting bifurcation behaviour in the asymptotic shape of the bubble in the limit it approaches extinction. In this limit, the boundary may tend to become either circular, or approach a line or ‘slit’ of zero thickness, depending on the initial condition and the value of a nondimensional surface tension parameter. We show that over a critical range of surface tension values, both these asymptotic shapes are stable. In this regime there exists a third, unstable branch of limiting self-similar bubble shapes, with an asymptotic aspect ratio (dependent on the surface tension) between zero and one. We support our asymptotic analysis with a numerical scheme that utilizes the applicability of complex variable theory to Hele-Shaw flow. (paper)

Scaling crossover in thin-film drag dynamics of fluid drops in the Hele-Shaw cell

Okumura, Ko; Yahashi, Misato; Kimoto, Natsuki

2016-11-01

We study both experimentally and theoretically the descending motion due to gravity of a fluid drop surrounded by another immiscible fluid in a confined space between two parallel plates, i.e., in the Hele-Shaw cell. As a result, we show a new scaling regime of a nonlinear drag friction in viscous liquid that replaces the well-known Stokes' drag friction through a clear collapse of experimental data thanks to the scaling law. In the novel regime, the dissipation in the liquid thin film formed between the drop and cell walls governs the dynamics. The crossover of this scaling regime to another scaling regime in which the dissipation inside the droplet is dominant is clearly demonstrated and a phase diagram separating these scaling regimes is presented.

Saffman-Taylor instability is a well known viscosity driven instability of an interface separating two immiscible fluids. We study linear stability of displacement processes in a Hele-Shaw cell involving an arbitrary number of immiscible fluid phases. This is a problem involving many interfaces. Universal stability results have been obtained for this multi-phase immiscible flow in the sense that the results hold for arbitrary number of interfaces. These stability results have been applied to design displacement processes that are considerably less unstable than the pure Saffman-Taylor case. In particular, we derive universal formula which gives specific values of the viscosities of the fluid layers corresponding to smallest unstable band. Other similar universal results will also be presented. The talk is based on the following paper. This work was supported by the Qatar National Research Fund (a member of The Qatar Foundation).

Cation ordering in orthopyroxenes and cooling rates of meteorites: Low temperature cooling rates of Estherville, Bondoc and Shaw

Science.gov (United States)

Ganguly, J.; Yang, H.; Ghose, S.

1993-01-01

The cooling rates of meteorites provide important constraints on the size of their parent bodies, and their accretionary and evolutionary histories. However, the cooling rates obtained so far from the commonly used metallographic, radiometric and fission-track methods have been sometimes quite controversial, such as in the case of the mesosiderites and the meteorite Shaw. We have undertaken a systematic study of the cooling rates of meteorites using a different approach, which involves single crystal x-ray determination of Fe(2+)-Mg ordering in orthopyroxenes (OP(x)) in meteorites, subject to bulk compositional constraints, and numerical simulation of the evolution of the ordering state as a function of cooling rate, within the framework of the thermodynamic and kinetic principles governing cation ordering. We report the results obtained for OP(x) crystals from Shaw and two mesosiderites, Estherville and Bondoc.

Shocks and finite-time singularities in Hele-Shaw flow

Energy Technology Data Exchange (ETDEWEB)

Teodorescu, Razvan [Los Alamos National Laboratory; Wiegmann, P [UNIV OF MONTREAL; Lee, S-y [UNIV OF CHICAGO

2008-01-01

Hele-Shaw flow at vanishing surface tension is ill-defined. In finite time, the flow develops cusplike singularities. We show that the ill-defined problem admits a weak dispersive solution when singularities give rise to a graph of shock waves propagating in the viscous fluid. The graph of shocks grows and branches. Velocity and pressure jump across the shock. We formulate a few simple physical principles which single out the dispersive solution and interpret shocks as lines of decompressed fluid. We also formulate the dispersive solution in algebro-geometrical terms as an evolution of Krichever-Boutroux complex curve. We study in details the most generic (2,3) cusp singularity which gives rise to an elementary branching event. This solution is self-similar and expressed in terms of elliptic functions.

Three dimensional vortices and interfaces in Hele-Shaw cells

International Nuclear Information System (INIS)

Pumir, A.

1987-06-01

A model of nonviscous flow, based on the Biot-Savart equations is used to examine the existence of singularities in three dimensional, incompressible, hydrodynamic equations. The results suggest a fairly simple physical mechanism, which could lead to the formation of singularities in the nonviscous case: two vortex tubes with opposite circulations pair up and stretch each other, until the radii of the vortex cores become extremely small, causing a divergence of the vorticity. The cases of a perfect and a slightly viscous fluid are considered. The results are unclear as to whether the vorticity of a slightly viscous fluid can become infinite or not, and whether singularities exist. The dynamics of hydrodynamic interfaces are also investigated. The propagation of bubbles in a slightly viscous fluid, in a Hele-Shaw cell are described [fr

Water resources of the Pittsburgh area, Pennsylvania

Noecker, Max; Greenman, D.W.; Beamer, N.H.

1954-01-01

The per capita use of water in the Pittsburgh area in 1951 was 2, 000 gallons per day fgpd) or twice the per capita use in Pennsylvania as a whole. An average of about 3, 040 million gallons of water was withdrawn from the streams and from the ground each day. Of this amount, nearly 190 million gallons per day (mgd), or 6 percent, was for domestic public water supply. Industry, including public utilities generating steam for electric energy, used approximately 2, 900 mgd, of which about 42 mgd was purchased from public supply sources. In spite of this tremendous demand for water, a sufficient quantity was available to satisfy the needs of the area without serious difficulty. Acid mine drainage presents the greatest single pollution problem in the Pittsburgh area at the present time (1953) because no practical means has been found for its control. The waters of several of the rivers are strongly acid for this reason. Of the three major rivers in the area, Monongahela River waters have the greatest acid concentration and Allegheny River waters the least. Untreated domestic and industrial wastes are additional sources of stream pollution in the area. Much of the water is hard and corrosive, and occasionally has objectionable color, odor, and taste. The treatment used by public water-supply systems using river water is adequate at all times for removal of water-borne causes of disease. Attention is being concentrated on improving the quality of present supplies rather than developing new supplies from upstream tributaries. Present supplies are being improved by providing treatment facilities for disposal of wastes,, by reduction of acid mine drainage discharged into the streams, and by providing storage to augment low flows. The underground water resources are vitally important to the area. The use of ground water in the Pittsburgh area has doubled in the past two decades and in 1951 more ground water was used in Allegheny County than in any other county in

The angle of repose of spherical grains in granular Hele–Shaw cells: a molecular dynamics study

International Nuclear Information System (INIS)

Maleki, Hamed; Ebrahimi, Fatemeh; Oskoee, Ehsan Nedaaee

2008-01-01

We report the results of three-dimensional molecular dynamic simulations on the angle of repose of a sandpile formed by pouring mono-sized cohesionless spherical grains into a granular Hele–Shaw cell. In particular, we are interested in investigating the effects of those variables which may have a significant impact on the pattern formation of granular mixtures in Hele–Shaw cells. The results indicate that the frictional forces influence the formation of piles on the grain level remarkably. Furthermore, we see that increasing grain insertion rate decreases the angle of repose slightly. We also find that the cell thickness is a significant factor and the angle of repose decays when the size of the gap between the lateral walls increases. In addition to agreeing with the experimental exponential decay law, our results are in accordance with a recently proposed model which takes into account the arching effects. Using grains with different sizes reveals that the behaviour of the angle of repose when both size and cell thickness are varied is controlled by a scaled function of the ratio of these two variables

Droplet formation in Hele-Shaw T-junction.

Ricouvier, Joshua; Yazhgur, Pavel; Leshansky, Alexander; Tabeling, Patrick; Microflusa Team

The development of digital microfluidics has attracted considerable interest towards generation of highly monodisperse microdroplets. T-junction has become an essential element of most of microfluidic chips. Despite its importance, theoretical analysis of droplet formation at T-junction is still incomplete due to complexity of physics involved. We focused on droplet generation at the Hele-Shaw T-junction. The effect of various experimental parameters, such as channel geometry, flow rates, surface tension and fluid viscosities, was thoroughly investigated. Our results show that the experimental system exhibits three distinct regimes (squeezing, dripping and jetting regimes) and point out the effect of confinement on the transitions. We demonstrate that the size of the ''plug'' droplet depends not only on the flow rate ratio (as described in the literature), but also on the capillary number and the channel cross-section aspect ratio. Quasi-2D flow equations allow us to perform numerical simulations and to compare them with experimental results.

Elements related to attrition of women faculty at the University of Pittsburgh, School of Medicine: A case study

Science.gov (United States)

Gandhi, Pooja

Recent studies have shown that the number of women faculty in academic medicine is much lesser than the number of women that are graduating from medical schools. Many academic institutes face the challenge of retaining talented faculty and this attrition from academic medicine prevents career advancement of women faculty. This case study attempts to identify some of the reasons for dissatisfaction that may be related to the attrition of women medical faculty at the University of Pittsburgh, School of Medicine. Data was collected using a job satisfaction survey, which consisted of various constructs that are part of a faculty's job and proxy measures to gather the faculty's intent to leave their current position at the University of Pittsburgh or academic medicine in general. The survey results showed that although women faculty were satisfied with their job at the University of Pittsburgh, there are some important factors that influenced their decision of potentially dropping out. The main reasons cited by the women faculty were related to funding pressures, work-life balance, mentoring of junior faculty and the amount of time spent on clinical responsibilities. The analysis of proxy measures showed that if women faculty decided to leave University of Pittsburgh, it would most probably be due to better opportunity elsewhere followed by pressure to get funding. The results of this study aim to provide the School of Medicine at the University of Pittsburgh with information related to attrition of its women faculty and provide suggestions for implications for policy to retain their women faculty.

Electrokinetic Fingering In Hele-Shaw Cells

Science.gov (United States)

Mirzadeh, Mohammad; Bazant, Martin

2016-11-01

Large scale flow problems in porous media, such as those encountered in underground oil reservoirs, are typically described by the Darcy's law. However, it is well known that many underground rock formations contain surface groups and minerals that dissociate in the presence of water. Convection of these charges by the pressure driven flow can then set up streaming current and streaming potential that affects the flow. Furthermore, electric fields that are often used to enhance oil recovery, e.g. by reducing the oil's viscosity through electro-thermal heating, drive electro-osmotic flows that could set up very large pressure in small pores. The full description of fluid flow thus requires a solution to the fully coupled electrokinetic problem. In their seminal work, Saffman and Taylor showed that the moving interface between two immiscible fluids in a porous medium becomes unstable if pushed by the low-viscosity fluid. Here we report on the role of electrokinetic phenomena on stability of these viscous fronts in Hele-Shaw cells by using analytic as well as numerical approaches. Interestingly, we find that the instability could be suppressed if the right physical conditions are met or otherwise enhanced, leading to greater mixing of two fluids.

Tsunakawa-Shaw method - an absolute paleointensity technique using alternating field demagnetization

Among geologic materials volcanic rocks have been typically used to deduce an absolute paleointensity. In the last decade, however, there seems a becoming consensus that volcanic rocks are not so ideal materials due to such as magnetic grains other than non-interacting single domain particles. One approach to obtain a good paleointensity estimate from the rocks is to reduce and correct the non-ideality, suppress alterations in laboratory and screen out suspicious results. We have been working on a development and an application of the Tsunakawa-Shaw method, which has been previously called the LTD-DHT Shaw method. This method is an AF(alternating field)-based technique and thus a paleointensity is estimated using coercivity spectra. To reduce the non-ideality, all remanences undergo low-temperature demagnetization (LTD) before any AF demagnetizations to remove multi-domain like component. To correct the non-ideality, anhysteretic remanent magnetizations (ARMs) are imparted with their directions parallel to natural remanent magnetizations and laboratory-imparted thermoremanent magnetizations (TRMs) and measured before and after laboratory heating. These ARMs are used to correct remanence anisotropies, possible interaction effects originated from the non-ideal grains and TRM changes caused by laboratory alterations. TRMs are imparted by heating specimens above their Curie temperatures and then cooling to room temperature at once to simulate nature conditions. These cycles are done in vacuum to suppress alterations in laboratory. Obtained results are judged by selection criteria, including a check for validity of the ARM corrections.It has been demonstrated that successful paleointensities are obtained from historical lavas in Japan and Hawaii, and from baked clay samples from a reconstructed ancient kiln, with the flow-mean precision of 5-10%. In case of old volcanic rocks, however, the method does not necessarily seem to be perfect. We will summarize these points in

Elastic fingering in rotating Hele-Shaw flows

KAUST Repository

Carvalho, Gabriel D.; Gadê lha, Hermes; Miranda, José A.

2014-01-01

The centrifugally driven viscous fingering problem arises when two immiscible fluids of different densities flow in a rotating Hele-Shaw cell. In this conventional setting an interplay between capillary and centrifugal forces makes the fluid-fluid interface unstable, leading to the formation of fingered structures that compete dynamically and reach different lengths. In this context, it is known that finger competition is very sensitive to changes in the viscosity contrast between the fluids. We study a variant of such a rotating flow problem where the fluids react and produce a gellike phase at their separating boundary. This interface is assumed to be elastic, presenting a curvature-dependent bending rigidity. A perturbative weakly nonlinear approach is used to investigate how the elastic nature of the interface affects finger competition events. Our results unveil a very different dynamic scenario, in which finger length variability is not regulated by the viscosity contrast, but rather determined by two controlling quantities: a characteristic radius and a rigidity fraction parameter. By properly tuning these quantities one can describe a whole range of finger competition behaviors even if the viscosity contrast is kept unchanged. © 2014 American Physical Society.

Centrifugal fingering in a curved Hele-Shaw cell: A generalized Euler's elastica shape for the two-fluid interface

Science.gov (United States)

Miranda, Jose; Brandao, Rodolfo

2017-11-01

We study a family of generalized elastica-like equilibrium shapes that arise at the interface separating two fluids in a curved rotating Hele-Shaw cell. This family of stationary interface solutions consists of shapes that balance the competing capillary and centrifugal forces in such a curved flow environment. We investigate how the emerging interfacial patterns are impacted by changes in the geometric properties of the curved Hele-Shaw cell. A vortex-sheet formalism is used to calculate the two-fluid interface curvature, and a gallery of possible shapes is provided to highlight a number of peculiar morphological features. A linear perturbation theory is employed to show that the most prominent aspects of these complex stationary patterns can be fairly well reproduced by the interplay of just two interfacial modes. The connection of these dominant modes to the geometry of the curved cell, as well as to the fluid dynamic properties of the flow, is discussed.

Wavelength selection in injection-driven Hele-Shaw flows: A maximum amplitude criterion

Science.gov (United States)

Dias, Eduardo; Miranda, Jose

2013-11-01

As in most interfacial flow problems, the standard theoretical procedure to establish wavelength selection in the viscous fingering instability is to maximize the linear growth rate. However, there are important discrepancies between previous theoretical predictions and existing experimental data. In this work we perform a linear stability analysis of the radial Hele-Shaw flow system that takes into account the combined action of viscous normal stresses and wetting effects. Most importantly, we introduce an alternative selection criterion for which the selected wavelength is determined by the maximum of the interfacial perturbation amplitude. The effectiveness of such a criterion is substantiated by the significantly improved agreement between theory and experiments. We thank CNPq (Brazilian Sponsor) for financial support.

Innovation in hydroelectric power plant design in early twentieth century. Casto Fernández-Shaw's Engineering Architecture in La Jándula dam

Directory of Open Access Journals (Sweden)

A. B. Berrocal Menárguez

2017-09-01

Full Text Available The power plant location in the first hydroelectrial dams was a relevant issue at the end of XIX century and early XX. Different solutions were tried, some of them with very interesting aesthetics results and hydraulic and structural implications. Such is the case of La Jándula dam, inaugurated in 1930, that includes the power station inside the dam. This article examines the possible national and international inspirations of this singular solution, corroborating the hypothesis of its unprecedented nature. The collaboration of the architect Casto Fernández-Shaw in the design and integration of the engine room was decisive, because it achieved a result of an aesthetic quality and formal expressiveness unprecedented in a work of hydraulic engineering, as well as the birth of a style Shaw himself defined as architectural engineering.

A study of gas bubbles in liquid mercury in a vertical Hele-Shaw cell

High-quality observations of mesoscopic gas bubbles in liquid metal are vital for a further development of pyrometallurgical gas injection reactors. However, the opacity of metals enforces the use of indirect imaging techniques with limited temporal or spatial resolution. In addition, accurate interface tracking requires tomography which further complicates the design of a high-temperature experimental setup. In this paper, an alternative approach is suggested that circumvents these two main restrictions. By injecting gas in a thin layer of liquid metal entrapped between two flat and closely spaced plates, bubbles in a Hele-Shaw flow regime are generated. The resulting quasi-2D multiphase flow phenomena can be fully captured from a single point of view and, when using a non-wetted transparent plate material, the bubbles can be observed directly. The feasibility of this approach is demonstrated by observations on buoyancy-driven nitrogen bubbles in liquid mercury in a vertical Hele-Shaw cell. By using a moving high-speed camera to make continuous close up recordings of individual bubbles, the position and geometry of these bubbles are quantified with a high resolution along their entire path. After a thorough evaluation of the experimental accuracy, this information is used for a detailed analysis of the bubble expansion along the path. While the observed bubble growth is mainly caused by the hydrostatic pressure gradient, a careful assessment of the volume variations for smaller bubbles shows that an accurate bubble description should account for significant dynamic pressure variations that seem to be largely regime dependent.

Interfacial elastic fingering in Hele-Shaw cells: A weakly nonlinear study

KAUST Repository

Carvalho, Gabriel D.

2013-11-11

We study a variant of the classic viscous fingering instability in Hele-Shaw cells where the interface separating the fluids is elastic, and presents a curvature-dependent bending rigidity. By employing a second-order mode-coupling approach we investigate how the elastic nature of the interface influences the morphology of emerging interfacial patterns. This is done by focusing our attention on a conventionally stable situation in which the fluids involved have the same viscosity. In this framework, we show that the inclusion of nonlinear effects plays a crucial role in inducing sizable interfacial instabilities, as well as in determining the ultimate shape of the pattern-forming structures. Particularly, we have found that the emergence of either narrow or wide fingers can be regulated by tuning a rigidity fraction parameter. Our weakly nonlinear findings reinforce the importance of the so-called curvature weakening effect, which favors the development of fingers in regions of lower rigidity. © 2013 American Physical Society.

Universality Results for Multi-Layer Hele-Shaw and Porous Media Flows

Saffman-Taylor instability is a well known viscosity driven instability of an interface. Motivated by a need to understand the effect of various injection policies currently in practice for chemical enhanced oil recovery, we study linear stability of displacement processes in a Hele-Shaw cell involving injection of an arbitrary number of immiscible fluid phases in succession. This is a problem involving many interfaces. Universal stability results have been obtained for this multi-layer (multi-region) flow in the sense that the results hold with arbitrary number of interfaces. These stability results have been applied to design injection policies that are considerably less unstable than the pure Saffman-Taylor case. In particular, we determine specific values of the viscosity of the fluid layers corresponding to smallest unstable band. Moreover, we discuss universal selection principle of optimal viscous profiles. The talk is based on following papers. Qatar National Fund (a member of the Qatar Foundation).

Gadolinium-based nanoparticles were functionalized with either the Pittsburgh compound B or a nanobody (B10AP) in order to create multimodal tools for an early diagnosis of amyloidoses. The ability of the functionalized nanoparticles to target amyloid fibrils made of β-amyloid peptide, amylin or Val30Met-mutated transthyretin formed in vitro or from pathological tissues was investigated by a range of spectroscopic and biophysics techniques including fluorescence microscopy. Nanoparticles functionalized by both probes efficiently interacted with the three types of amyloid fibrils, with K D values in 10 micromolar and 10 nanomolar range for, respectively, Pittsburgh compound B and B10AP nanoparticles. Moreover, they allowed the detection of amyloid deposits on pathological tissues. Such functionalized nanoparticles could represent promising flexible and multimodal imaging tools for the early diagnostic of amyloid diseases, in other words, Alzheimer's disease, Type 2 diabetes mellitus and the familial amyloidotic polyneuropathy.

Using an objective scoring system, chest radiographs were reviewed in 23 cases of pneumonia due to the Pittsburgh pneumonia agent (PPA, Tatlockia micdadei, Legionella micdadei), including six cases of pneumonia with simultaneous isolation of PPA and L pneumophila (Legionnaires' disease). Infiltrates were typically segmental to lobar; nodular infiltrates were noted in three cases. Spread to additional lobes after presentation occurred in four of 17 PPA infections. Pneumonia caused by both PPA and L pneumophila was unusually severe, with involvement of all lobes occurring in four of six cases, compared with one of 17 cases of PPA infection (p>0.02). Radiographic severity did not correlate with underlying disease, immune status, or outcome. The majority of patients receiving erythromycin demonstrated objective radiologic improvement. In a patients, population that included nonimmunosuppressed patient, nodule formation and rapid radiologic progression were not found to be characteristic of PPA pneumonia

Sparkes, Steven T.; Patel, Dhiren K.

2014-01-01

Objective: To review why metformin is considered first-line therapy for type 2 diabetes mellitus (T2DM) and review newer avenues of research currently being evaluated. Data Sources: The Cochrane Library and Medline (to January 2014) were searched for case–control and cohort studies, clinical trials, and systematic reviews and meta-analyses involving metformin for any indication. Study Selection and Data Extraction: The literature search found 5 major avenues of research for metformin: reduction in mortality, delayed-onset or prevention of T2DM in the presence of prediabetes, nonalcoholic fatty liver disease (NAFLD), polycystic ovarian syndrome (PCOS), and decreased cancer risk. When available, multi-center, double-blind, controlled clinical trials or meta-analyses thereof were selected for review. If these types of studies did not exist, other types of studies were chosen for review. Data Synthesis: Metformin significantly decreases all-cause and diabetes-related mortality in overweight and obese patients with T2DM. It may also decrease risk of progression to T2DM in patients with prediabetes. Metformin has been studied for the treatment of NAFLD though data are limited. Metformin alone or combined with clomiphene may increase pregnancy and ovulation rates but has not yet been shown to increase live-birth rates in patients with PCOS. Metformin may decrease risk of colorectal cancer but not all-cancer risk. Conclusions: Metformin’s clinical role in T2DM and prediabetes is well established. Other avenues of research being evaluated at this time are NAFLD, PCOS, and reduced risk of cancer; more data are needed before it has a clinical role in these indications.

When the mobility difference is primarily attributable to viscosity (e.g., flow between the two horizontal plates of a Hele-Shaw cell), viscous fingering (VF) occurs, which is sometimes termed the Saffman-Taylor instability. Alternatively, in the presence of differences in density in a gravity field, buoyancy-driven convection can occur. These instabilities have been studied for decades, in part because of their many applications in pollutant dispersal, ocean currents, enhanced petroleum recovery, and so on. More recent interest has emerged regarding the effects of chemical reactions on fingering instabilities. As chemical reactions change the key flow parameters (densities, viscosities, and concentrations), they may have either a destabilizing or stabilizing effect on the flow. Hence, new flow patterns can emerge; moreover, one can then hope to gain some control over flow instabilities through reaction rates, flow rates, and reaction products. We report effects of chemical reactions on VF in a Hele-Shaw cell for a reactive step-growth cross-linking polymerization system. The cross-linked reaction product results in a non-monotonic viscosity profile at the interface, which affects flow stability. Furthermore, three-dimensional internal flows influence the long-term pattern that results.

Results of the radiological survey at the former Heppenstall Company site, 4620 Hatfield Street, Pittsburgh, Pennsylvania

As part of the Formerly Utilized Sites Remedial Action Program, the US Department of Energy (DOE) is implementing a program to determine the radiological conditions at sites that were used to process radioactive materials under contract with the department's predecessor agencies. During 1955 the former Heppenstall Company site in Pittsburgh, Pennsylvania, was used by an Atomic Energy Commission contractor to process approximately 100,000 lbs of normal uranium metal. Because of insufficient records to document cleanup procedures and to verify the radiological condition of this site, DOE requested a survey. The radiological survey discussed in this report for the site of the former Heppenstall Company, Pittsburgh, Pennsylvania, was conducted by members of the Measurement Applications and Development Group of Oak Ridge National Laboratory in July of 1989. The survey included a surface gamma scan of the warehouse, collection of indoor soil and dust samples and one outdoor sample, and measurement of direct and transferable alpha and beta-gamma activity. Results of this radiological assessment indicate no detection of radiation levels or radionuclide concentrations above DOE guidelines. 7 refs., 5 figs., 3 tabs

Osnes, A. N.; Vartdal, M.; Pettersson Reif, B. A.

The formation of jets from a shock-accelerated cylindrical shell of particles, confined in a Hele-Shaw cell, is studied by means of numerical simulation. A number of simulations have been performed, systematically varying the coupling between the gas and solid phases in an effort to identify the primary mechanism(s) responsible for jet formation. We find that coupling through drag is sufficient for the formation of jets. Including the effect of particle volume fraction and particle collisions did not alter the general behaviour, but had some influence on the length, spacing and number of jets. Furthermore, we find that the jet selection process starts early in the dispersal process, during the initial expansion of the particle layer.

Rayleigh-Benard convection in a Hele-Shaw cell - a numerical study

International Nuclear Information System (INIS)

Guenther, C.; Mueller, U.

1987-05-01

Free convection in narrow vertical gaps heated from below gives rise to several different flow patterns as has been demonstrated by previous experimental investigations. A numerical study is presented aimed at simulating the observed flow phenomena in Hele-Shaw cells of small lateral extend. The numerical study is based on the assumption that the flow is essentially two-dimensional. This allows an approach using a one-term Galerkin approximation with respect to the direction perpendicular to the gap and a finite difference scheme with regard to the coordinates in the plane of the gap. The calculations result in realistic values of the critical Rayleigh numbers for the onset of steady and oscillatory convection. Most of the observed unsteady flow patterns can be simulated numerically. It is shown that five different stable flow patterns can occur at one particular Rayleigh number. The different stable flow patterns are coupled by a variety of complex transitions. Moreover the calculations show that a realistic description of the observed flow phenomena can not be obtained by a simplified model using the Darcy law in the momentum equation and implying slip flow at the small confining boundaries.

This paper reviews key findings on juvenile mental health problems in boys, psychopathy, and personality traits, obtained in the first 14 years of studies using data from the Pittsburgh Youth Study. This is a study of 3 samples, each of about 500 boys initially randomly drawn from boys in the 1st, 4th, and 7th grades of public schools in Pittsburgh. The boys have been followed regularly, initially each half year, and later at yearly intervals. Currently, the oldest boys are about 25 years old, whereas the youngest boys are about 19. Findings are presented on the prevalence and interrelation of disruptive behaviors, ADHD, and depressed mood. Results concerning risk factors for these outcomes are reviewed. Psychological factors such as psychopathy, impulsivity, and personality are described. The paper closes with findings on service delivery of boys with mental health problems.

Pollutant Concentrations in Street Canyons of Different Aspect Ratio with Avenues of Trees for Various Wind Directions

Gromke, Christof; Ruck, Bodo

2012-07-01

This study summarizes the effects of avenues of trees in urban street canyons on traffic pollutant dispersion. We describe various wind-tunnel experiments with different tree-avenue models in combination with variations in street-canyon aspect ratio W/ H (with W the street-canyon width and H the building height) and approaching wind direction. Compared to tree-free street canyons, in general, higher pollutant concentrations are found. Avenues of trees do not suppress canyon vortices, although the air ventilation in canyons is hindered significantly. For a perpendicular wind direction, increases in wall-average and wall-maximum concentrations at the leeward canyon wall and decreases in wall-average concentrations at the windward wall are found. For oblique and perpendicular wind directions, increases at both canyon walls are obtained. The strongest effects of avenues of trees on traffic pollutant dispersion are observed for oblique wind directions for which also the largest concentrations at the canyon walls are found. Thus, the prevailing assumption that attributes the most harmful dispersion conditions to a perpendicular wind direction does not hold for street canyons with avenues of trees. Furthermore, following dimensional analysis, an estimate of the normalized wall-maximum traffic pollutant concentration in street canyons with avenues of trees is derived.

Levine, Arthur S; McDonald, Margaret C; Bogosta, Charles E

2017-10-01

In 2011, the University of Pittsburgh School of Medicine (UPSOM) and Tsinghua University formed a partnership to further the education of Tsinghua medical students. These students come to UPSOM as visiting research scholars for two years of their eight-year MD curriculum. During this time, the students, who have completed four years at Tsinghua, work full-time in medical school laboratories and research programs of their choice, essentially functioning as graduate students. In their first two months in Pittsburgh, the scholars have a one-week orientation to biomedical research, followed by two-week rotations in four labs selected on the basis of the scholars' scientific interests, after which they choose one of these labs for the remainder of the two years. Selected labs may be in basic science departments, basic science divisions of clinical departments, or specialized centers that focus on approaches like simulation and modeling. The Tsinghua students also have a brief exposure to clinical medicine. UPSOM has also formed a similar partnership with Central South University Xiangya School of Medicine in Changsha, Hunan Province. The Xiangya students come to UPSOM for two years of research training after their sixth year and, thus, unlike the Tsinghua students, have already completed their clinical rotations. UPSOM faculty members have also paved the way for UPMC (University of Pittsburgh Medical Center), UPSOM's clinical partner, to engage with clinical centers in China. Major relationships involving advisory, training, managerial, and/or equity roles exist with Xiangya International Medical Center, KingMED Diagnostics, First Chengmei Medical Industry Group, and Macare Women's Hospital. Both UPSOM and UPMC are actively exploring other clinical and academic opportunities in China.

Radon concentrations inside public and commercial buildings in the Pittsburgh area

Energy Technology Data Exchange (ETDEWEB)

Cohen, B L; Kulwicki, D R; Warner, Jr, K R; Grassi, C L

1984-09-01

Radon concentrations in ambient air from numerous schools, stores and other public and commercial buildings in the Pittsburgh, PA, area were measured by grab sampling. This is more appropriate than using long-term integrating monitors because of the correlation between times of occupancy and Rn levels. Results indicate that Rn concentrations in these buildings are nearly an order of magnitude less than in homes, and not much higher than outdoors. Variations among sites is also much less than for homes, probably because there is less variability in ventilation and building maintenance practices. Colleges and universities have somewhat higher Rn levels and a larger degree of variability than commercial buildings or hospitals. There was no indication of higher Rn levels in cold weather than in warm weather, or of correlations with the age of the building.

Of mice and men: evolution and the socialist utopia. William Morris, H.G. Wells, and George Bernard Shaw.

Science.gov (United States)

Hale, Piers J

2010-01-01

During the British socialist revival of the 1880s competing theories of evolution were central to disagreements about strategy for social change. In News from Nowhere (1891), William Morris had portrayed socialism as the result of Lamarckian processes, and imagined a non-Malthusian future. H.G. Wells, an enthusiastic admirer of Morris in the early days of the movement, became disillusioned as a result of the Malthusianism he learnt from Huxley and his subsequent rejection of Lamarckism in light of Weismann's experiments on mice. This brought him into conflict with his fellow Fabian, George Bernard Shaw, who rejected neo-Darwinism in favour of a Lamarckian conception of change he called "creative evolution."

Bubble propagation in Hele-Shaw channels with centred constrictions

Science.gov (United States)

Franco-Gómez, Andrés; Thompson, Alice B.; Hazel, Andrew L.; Juel, Anne

2018-04-01

We study the propagation of finite bubbles in a Hele-Shaw channel, where a centred occlusion (termed a rail) is introduced to provide a small axially uniform depth constriction. For bubbles wide enough to span the channel, the system’s behaviour is similar to that of semi-infinite fingers and a symmetric static solution is stable. Here, we focus on smaller bubbles, in which case the symmetric static solution is unstable and the static bubble is displaced towards one of the deeper regions of the channel on either side of the rail. Using a combination of experiments and numerical simulations of a depth-averaged model, we show that a bubble propagating axially due to a small imposed flow rate can be stabilised in a steady symmetric mode centred on the rail through a subtle interaction between stabilising viscous forces and destabilising surface tension forces. However, for sufficiently large capillary numbers Ca, the ratio of viscous to surface tension forces, viscous forces in turn become destabilising thus returning the bubble to an off-centred propagation regime. With decreasing bubble size, the range of Ca for which steady centred propagation is stable decreases, and eventually vanishes through the coalescence of two supercritical pitchfork bifurcations. The depth-averaged model is found to accurately predict all the steady modes of propagation observed experimentally, and provides a comprehensive picture of the underlying steady bifurcation structure. However, for sufficiently large imposed flow rates, we find that initially centred bubbles do not converge onto a steady mode of propagation. Instead they transiently explore weakly unstable steady modes, an evolution which results in their break-up and eventual settling into a steady propagating state of changed topology.

Metals in soils adjacent to avenues of highly dense traffic of Sao Paulo city, Brazil

Sao Paulo is the largest city in Brazil with about 19 millions of inhabitants in the metropolitan area, more than 8 million motor vehicles and strong industrial activity at the metropolitan region, which are responsible for increasing pollution in the region. Nevertheless, there is little information on metal contents in the metropolitan region soils, which would be very useful as a fingerprint of the environmental pollution. The present study aimed to determine As, Ba, Co, Cr, Sb and Zn concentrations in soils adjacent to avenues of highly dense traffic downtown Sao Paulo city: Consolacao/Reboucas Avenues; 23 de Maio Avenue and Tiradentes Avenue, to assess their possible sources and potential environmental impact. The analytical technique employed was Instrumental Neutron Activation Analysis (INAA). The results show metal concentration levels higher than the values reference values for soils of Sao Paulo, according to the Environmental Protection Agency of the State Sao Paulo (CETESB) guidelines. As, Ba and Zn showed concentration levels above the Intervention Values in some points, indicating direct or indirect potential risks to human health. The traffic related element Ba, Sb and Zn presented concentrations above the Prevention Values in points with high density traffic and may be associated to vehicular emissions. (author)

Instability of displacement of Oldroyd-B fluid by air in a Hele-Shaw cell

Science.gov (United States)

Daripa, Prabir

2014-03-01

We study the displacement of an Oldroyd-B fluid in a Hele-Shaw cell when driven by air. In particular, we explicitly obtain an analytical expression for the growth rate of instability which depends on the relaxation and retardation (time) constants, denoted by λ, and λ1 respectively, appearing in the Oldroyd-B constitutive relations. When these two constants are zero, we recover the classical Saffman-Taylor result for a Newtonian liquid displaced by air. Our results show that this displacement process is more unstable than the case when a Newtonian fluid is displaced by air. The analytical results are plotted and compared with numerical results on this unstable displacement process available in the literature. The agreement is found to be excellent. In particular, results show that the non-Newtonian case (i.e., Oldroyd-B) is more unstable than the Newtonian case.

Structure of thallium and lead calculated from Shaw local pseudopotential and molecular dynamics

Directory of Open Access Journals (Sweden)

2011-05-01

Full Text Available Recently, we (Es Sbihi Phil. Mag 2010 have successfully calculated, by molecular dynamics, the static structure factor of liquid bismuth at different temperatures. Our results were in very good agreement with the Waseda experimental data. Our assumption was to consider the true density of states which presents a gap as measured by Indlekofer (J. Non-Cryst. Solids 1989 and calculated by Hafner-Jank (Phys. Rev. B 1990 for liquid bismuth. The number of electrons at the Fermi energy has been calculated with three conduction electrons for bismuth (number of p electrons. With this assumption, the structures were determined with an effective ion-ion potential constructed from the Shaw local Optimised Model Potential (OMP and the Ichimaru-Utsumi dielectric function. In the present paper, we generalize our assumptions to liquid thallium and lead which also present such a gap. Their calculated structures are also very close to the experimental ones. This confirms that the number of conduction electrons on the Fermi sphere is consistent with the number of p electrons as has been even shown for our electronic transport properties of liquid lead (A.

An avenue of eddies: Quantifying the biophysical properties of mesoscale eddies in the Tasman Sea

Science.gov (United States)

Everett, J. D.; Baird, M. E.; Oke, P. R.; Suthers, I. M.

2012-08-01

The Tasman Sea is unique - characterised by a strong seasonal western boundary current that breaks down into a complicated field of mesoscale eddies almost immediately after separating from the coast. Through a 16-year analysis of Tasman Sea eddies, we identify a region along the southeast Australian coast which we name ‘Eddy Avenue’ where eddies have higher sea level anomalies, faster rotation and greater sea surface temperature and chlorophyll a anomalies. The density of cyclonic and anticyclonic eddies within Eddy Avenue is 23% and 16% higher respectively than the broader Tasman Sea. We find that Eddy Avenue cyclonic and anticyclonic eddies have more strongly differentiated biological properties than those of the broader Tasman Sea, as a result of larger anticyclonic eddies formed from Coral Sea water depressing chl. a concentrations, and for coastal cyclonic eddies due to the entrainment of nutrient-rich shelf waters. Cyclonic eddies within Eddy Avenue have almost double the chlorophyll a (0.35 mg m-3) of anticyclonic eddies (0.18 mg m-3). The average chlorophyll a concentration for cyclonic eddies is 16% higher in Eddy Avenue and 28% lower for anticyclonic eddies when compared to the Tasman Sea. With a strengthening East Australian Current, the propagation of these eddies will have significant implications for heat transport and the entrainment and connectivity of plankton and larval fish populations.

Growth of fingers at an unstable diffusing interface in a porous medium or hele-shaw cell

Energy Technology Data Exchange (ETDEWEB)

Wooding, R A

1969-11-27

Waves at an unstable horizontal interface, between 2 fluids moving vertically through a saturated porous medium, are observed to grow rapidly to become fingers (i.e., the amplitude greatly exceeds the wavelength). For a diffusing interface, in experiments using a Hele-Shaw cell, the mean amplitude taken over many fingers grows approx. as (time)U2D, followed by a transition to a growth proportional to time. Correspondingly, the mean wave number decreases approx. as (time)U-1/2D. Because of the rapid increase in amplitude, longitudinal dispersion ultimately becomes negligible relative to wave growth. To represent the observed quantities at large time, the transport equation is suitably weighted and averaged over the horizontal plane. Hyperbolic equations result, and the ascending and descending zones containing the fronts of the fingers are replaced by discontinuities. These averaged equations form an open set, but closure is achieved by assuming a law for the mean wave number based on similarity. (22 refs.)

The ability to meet this imperative is challenging as universities confront declining financial resources and increasing complexity of the research enterprise. The authors describe the University of Pittsburgh's design, implementation, and evaluation of a Web-based, institution-wide RCR training program called Research and Practice Fundamentals (RPF). This project, established in 2000, was embedded in the philosophy, organizational structure, and technology developed through the Integrated Advanced Information Management Systems grant from the National Library of Medicine. Utilizing a centralized, comprehensive approach, the RPF system provides an efficient mechanism for deploying content to a large, diverse cohort of learners and supports the needs of research administrators by providing access to information about who has successfully completed the training. During its first 3 years of operation, the RPF served over 17,000 users and issued more than 38,000 training certificates. The 18 modules that are currently available address issues required by regulatory mandates and other content areas important to the research community. RPF users report high levels of satisfaction with content and ease of using the system. Future efforts must explore methods to integrate non-RCR education and training into a centralized, cohesive structure. The University of Pittsburgh's experience with the RPF demonstrates the importance of developing an infrastructure for training that is comprehensive, scalable, reliable, centralized, affordable, and sustainable.

2016-04-01

Full Text Available Since the 1990s, governance changes, including customer choice agendas, have permeated the public sector and, consequently, welfare sector professionals’ work. One example is the education sector. The aim of this paper is to identify and discuss avenues for further research when it comes to teachers’ working conditions in the light of current choice agendas. This is accomplished by presenting an overview of previous studies on implications of the reforms for teachers’ working conditions. How are these conditions described in relation to the current school choice agenda in Sweden? What directions should be applied to increase knowledge of these conditions? We conclude by identifying some avenues for further research: the issues of organization of work, temporal and spatial dimensions of working conditions, and finally comparative studies of various forms, are suggested as warranting further investigation to highlight the diversified labor market in which teachers find themselves today.Keywords: Competition, governance change, privatization, professional work, school choice, Sweden, teaching profession, working conditions

Avenues for crowd science in Hydrology.

Science.gov (United States)

Koch, Julian; Stisen, Simon

2016-04-01

Crowd science describes research that is conducted with the participation of the general public (the crowd) and gives the opportunity to involve the crowd in research design, data collection and analysis. In various fields, scientists have already drawn on underused human resources to advance research at low cost, with high transparency and large acceptance of the public due to the bottom up structure and the participatory process. Within the hydrological sciences, crowd research has quite recently become more established in the form of crowd observatories to generate hydrological data on water quality, precipitation or river flow. These innovative observatories complement more traditional ways of monitoring hydrological data and strengthen a community-based environmental decision making. However, the full potential of crowd science lies in internet based participation of the crowd and it is not yet fully exploited in the field of Hydrology. New avenues that are not primarily based on the outsourcing of labor, but instead capitalize the full potential of human capabilities have to emerge. In multiple realms of solving complex problems, like image detection, optimization tasks, narrowing of possible solutions, humans still remain more effective than computer algorithms. The most successful online crowd science projects Foldit and Galaxy Zoo have proven that the collective of tens of thousands users could clearly outperform traditional computer based science approaches. Our study takes advantage of the well trained human perception to conduct a spatial sensitivity analysis of land-surface variables of a distributed hydrological model to identify the most sensitive spatial inputs. True spatial performance metrics, that quantitatively compare patterns, are not trivial to choose and their applicability is often not universal. On the other hand humans can quickly integrate spatial information at various scales and are therefore a trusted competence. We selected

2003-01-01

The 2003 results for the Bettis-Pittsburgh radiological and nonradiological environmental monitoring programs are presented. The results demonstrate that the existing procedures ensured that releases to the environment during 2003 were in accordance with applicable Federal, State, County, and local regulations. Evaluation of the environmental data indicates that current operations at the Site continue to have no adverse effect on human health and the quality of the environment. A conservative assessment of radiation exposure to the general public as a result of Site operations demonstrates that the dose received by any member of the public was well below the most restrictive dose limits established by the Environmental Protection Agency, the Nuclear Regulatory Commission, and the U.S. Department of Energy. A risk assessment of potentially exposed populations to chemical residues in the environment at the Site demonstrates that any potential risk posed by these residues in much less than the risks encountered in normal everyday life

The prevalence of Clostridium difficile in retail meat samples has varied widely. The food supply may be a source for C. difficile infections. A total of 102 ground meat and sausage samples from 3 grocers in Pittsburgh, PA, were cultured for C. difficile. Brand A pork sausages were resampled between May 2011 and January 2012. Two out of 102 (2.0%) meat products initially sampled were positive for C. difficile; both were pork sausage from brand A from the same processing facility (facility A). On subsequent sampling of brand A products, 10/19 samples from processing facility A and 1/10 samples from 3 other facilities were positive for C. difficile. The isolates recovered were inferred ribotype 078, comprising 6 genotypes. The prevalence of C. difficile in retail meat may not be as high as previously reported in North America. When contamination occurs, it may be related to events at processing facilities.

Propagation of a finite bubble in a Hele-Shaw channel of variable depth

Juel, Anne; Franco-Gomez, Andres; Thompson, Alice; Hazel, Andrew

2017-11-01

We study the propagation of finite bubbles in a Hele-Shaw channel, where a centred rail is introduced to provide a small axially-uniform depth constriction. We demonstrate experimentally that this channel geometry can be used as a passive sorting device. Single air bubbles carried within silicone oil are generally transported on one side of the rail. However, for flow rates marginally larger than a critical value, a narrow band of bubble sizes on the order of the rail width can propagate over the rail, while bubbles of other sizes segregate to the side of the rail. The width of this band of bubble sizes increases with flow rate and the size of the most stable bubble can be tuned by varying the rail width. We present a depth-averaged theory which reveals that the mechanism relies on a non-trivial interaction between capillary and viscous forces that is fully dynamic, rather than being a simple modification of capillary static solutions. In contrast, for larger bubbles and sufficiently large imposed flow rates, we find that initially centred bubbles do not converge onto a steady mode of propagation. Instead they transiently explore weakly unstable steady modes, an evolution which results in their break-up and eventual settling into a steady state of changed topology.

Creating a Methodology for Coordinating High-resolution Air Quality Improvement Map and Greenhouse Gas Mitigation Strategies in Pittsburgh City

Science.gov (United States)

Shi, J.; Donahue, N. M.; Klima, K.; Blackhurst, M.

2016-12-01

In order to tradeoff global impacts of greenhouse gases with highly local impacts of conventional air pollution, researchers require a method to compare global and regional impacts. Unfortunately, we are not aware of a method that allows these to be compared, "apples-to-apples". In this research we propose a three-step model to compare possible city-wide actions to reduce greenhouse gases and conventional air pollutants. We focus on Pittsburgh, PA, a city with consistently poor air quality that is interested in reducing both greenhouse gases and conventional air pollutants. First, we use the 2013 Pittsburgh Greenhouse Gas Inventory to update the Blackhurst et al. model and conduct a greenhouse gas abatement potentials and implementation costs of proposed greenhouse gas reduction efforts. Second, we use field tests for PM2.5, NOx, SOx, organic carbon (OC) and elemental carbon (EC) data to inform a Land-use Regression Model for local air pollution at a 100m x 100m spatial level, which combined with a social cost of air pollution model (EASIUR) allows us to calculate economic social damages. Third, we combine these two models into a three-dimensional greenhouse gas cost abatement curve to understand the implementation costs and social benefits in terms of air quality improvement and greenhouse gas abatement for each potential intervention. We anticipated such results could provide policy-maker insights in green city development.

Equity in Microscale Urban Design and Walkability: A Photographic Survey of Six Pittsburgh Streetscapes

Bradley Bereitschaft

2017-07-01

Full Text Available This paper explores inequity in neighborhood walkability at the micro-scale level by qualitatively examining six streetscapes in Pittsburgh, Pennsylvania. A photographic survey is used to highlight differences in the quality and design of the built environment among pairs of streetscapes with high or low social vulnerability but approximately equal quantitative Walk Scores®. The survey revealed discernable differences in the quality and maintenance of the built environment among those in more and less disadvantaged neighborhoods. This was true of several characteristics expected to affect walkability, including enclosure, transparency, complexity, and tidiness. Streetscapes in neighborhoods with high social vulnerability exhibited less contiguous street walls, fewer windows and less transparent storefronts, less well maintained infrastructure, fewer street cafés, and overall less complexity than those in neighborhoods with low social vulnerability. Implications for planning and policy are discussed.

Growth-direction dependence of steady-state Saffman-Taylor flow in an anisotropic Hele-Shaw cell

McCloud, K.V.; Maher, J.V.

1996-01-01

Selection of steady-state fingers has been measured in a Hele-Shaw cell perturbed by having a square lattice etched onto one of the plates. Flows at different orientations θ between the direction of flow and the lattice axes have been studied, in a wide range of observable tip velocities where the perturbation was made microscopic in the sense that the capillary length of the flow was much greater than the etched lattice cell size. The full range of dynamically interesting angles for the square lattice was examined, and above a threshold, the microscopic perturbation always results in wider fingers than are selected in the unperturbed case. There is some dependence of the width of the fingers on the orientation of the flow, with fingers at θ=0 degree being the widest with respect to the unperturbed fingers, and fingers at 45 degree being the least wide, although still wider than the unperturbed fingers. All observed solutions are symmetric, centered in the channel, and have the relation between tip-curvature and finger width expected of members of the Saffman-Taylor family of solutions. Selected solutions narrow again at tip velocities where the perturbation can no longer be considered microscopic. copyright 1996 The American Physical Society

This work analysed different 5 cm depth fragments soils, with distinct characteristic s, collected at 8 points of the Tiete river marginal avenue at the Sao Paulo metropolitan region. The technique used for the analysis was the instrumental neutron activation analysis (INAA). Together with samples, metal concentration were measured in three reference materials BEN (IWG-GIT), GS-N (IWG-GIT) and Soil-7 (IAEA) for quality control of the results. These metals were analysed: arsenic (As), barium (Ba), chromium (Cr), cobalt (Co), antimony (Sb) e zinc (Zn); the obtained concentrations were compared with intervention limit values stipulated by the Companhia de Tecnologia de Saneamento Ambiental (CETESB). Those values indicate the soil quality for different use

The Revival of Memory: Gardens and Avenues of Remembrance. Early Results of a Research in Abruzzo

Aldo Giorgio Pezzi

2014-06-01

Full Text Available The forthcoming centenary of the Great War (1914-1918 can be considered an important occasion to focus attention on the subject of memorials for the fallen in the War. Immediately after the War, this topic was considered so relevant that in each municipality of Italy, Gardens and Avenues of Remembrance were realized and soon became places of memory, characterized by strong values of identity, history and landscape. In these places, usually correspondent to the number of fallen in that neighbourhood and located in urban or peripheral areas, nature and anthropic elements coexisted. For their importance, from 1926 these places have been included among the National Monuments. After the Second World War, avenues and gardens, as well as toponyms, were gradually forgotten and, in many cases, radically transformed. Due to a form of damnatio memoriae, which locations considered symbols of past governments have had to pay, these places have been changed, radically transforming also their authentic significance. A century on, it is important to start a programme for protection and enhancement of this historic heritage (classification at a regional and national scale, measurements, archival research, definition of guide lines for conservation. The essay also describes the early results of the classification of Gardens and Avenues of Remembrance in Abruzzo.

Natural convection heat transfer and flow structure in an anisotropic porous medium of square cavity saturated with Boussinesq fluid has been studied experimentally using a Hele-Shaw cell. The permeability ratio defined by K=K{sub y}/K{sub x} was put to three different values; 0.4, 1 and 2.5. The convection patterns at three different permeability ratios are visualized for several different Rayleigh numbers by the pH indicator method. When K is 0.25, the visualized flow is mainly in the vertical direction. On the contrary for K=4 the convecting flow is in the horizontal direction. The average heat transfer coefficients are also measured, and the corresponding Nusselt number are plotted as a function of K. It is found that the corresponding Nusselt numbers are scaled with (KRa){sup 1/2}. The experimental results of flow pattern and heat transfer are accord with those obtained by our previous theory.

Industrial Restructuring and Urban Change in the Pittsburgh Region: Developmental, Ecological, and Socioeconomic Trade-offs

Directory of Open Access Journals (Sweden)

William Haller

2005-06-01

Full Text Available This article traces the steel industry's restructuring during the 1980s and its consequences for older industrial regions tied historically to steel production. These regions contained large working-class communities that declined because of deindustrialization and restructuring. This article first examines the transition of the steel industry from its roots in extractive and primary manufacturing to a scrap-recycling industry that minimizes labor and raw material inputs. This transition parallels the structural changes in other industries addressed by political economic perspectives, such as the new international division of labor and globalization of production. The article then focuses on the socioeconomic and structural changes, using the Pittsburgh region as an example, including the employment and land-use consequences of deindustrialization and the relationship between losses in manufacturing employment and increases in persistent joblessness and poverty associated with growth of the urban underclass.

Determination of the size of the gas emission zone, the locations of gas sources within, and especially the amount of gas retained in those zones is one of the most important steps for designing a successful methane control strategy and an efficient ventilation system in longwall coal mining. The formation of the gas emission zone and the potential amount of gas-in-place (GIP) that might be available for migration into a mine are factors of local geology and rock properties that usually show spatial variability in continuity and may also show geometric anisotropy. Geostatistical methods are used here for modeling and prediction of gas amounts and for assessing their associated uncertainty in gas emission zones of longwall mines for methane control.This study used core data obtained from 276 vertical exploration boreholes drilled from the surface to the bottom of the Pittsburgh coal seam in a mining district in the Northern Appalachian basin. After identifying important coal and non-coal layers for the gas emission zone, univariate statistical and semivariogram analyses were conducted for data from different formations to define the distribution and continuity of various attributes. Sequential simulations performed stochastic assessment of these attributes, such as gas content, strata thickness, and strata displacement. These analyses were followed by calculations of gas-in-place and their uncertainties in the Pittsburgh seam caved zone and fractured zone of longwall mines in this mining district. Grid blanking was used to isolate the volume over the actual panels from the entire modeled district and to calculate gas amounts that were directly related to the emissions in longwall mines.Results indicated that gas-in-place in the Pittsburgh seam, in the caved zone and in the fractured zone, as well as displacements in major rock units, showed spatial correlations that could be modeled and estimated using geostatistical methods. This study showed that GIP volumes may

Influence of avenue-trees on air quality at the urban neighborhood scale. Part II: traffic pollutant concentrations at pedestrian level.

Gromke, Christof; Blocken, Bert

2015-01-01

Flow and dispersion of traffic-emitted pollutants were studied in a generic urban neighborhood for various avenue-tree layouts by employing 3D steady RANS simulations with the realizable k-ε turbulence model. In comparison to the tree-free situation quantitative and qualitative changes with flow reversal in the wind field were observed. Low to moderate increases (pollutant concentration were found at pedestrian level. An approximately 1% increase in the neighborhood-averaged concentration was obtained with each percent of the street canyon volumes being occupied by vegetation for occupation fractions between 4 and 14%. The overall pattern of concentration changes relative to the tree-free situation was similar for all avenue-tree layouts. However, pronounced locally restricted decreases or increases in concentration (-87 to +1378%) occurred. The results indicate the necessity to account for existing or planned avenue-trees in neighborhood scaled is dispersion studies. Their consideration is prerequisite for reliable urban air quality assessment.

Customer perceived value—Conceptualization and avenues for future research

Directory of Open Access Journals (Sweden)

Alexander Zauner

2015-12-01

Full Text Available Given the present dynamic consumption environment due to technological innovations as well as interlinked economic developments on the macro-, micro-, and societal-level, researchers and managers have been increasingly showing interest in the concept of customer perceived value. However, especially given its vast empirical application, surprisingly little effort has been paid to synthesize various perspectives on the dimensionality, abstraction, and model taxonomy of customer perceived value. Therefore, based on a comprehensive literature review, this article identifies the predominant conceptualization of customer perceived value, thus also providing a sound basis for future empirical assessments of this concept, and discusses avenues for future research. In addition to contributing to research, this study also contributes to practice by comprehensively positioning customer perceived value as a key source of competitive advantage in the context of relationship marketing, management, and business models.

Autonomy, Affinity, and the Assessment of Damages: Acb v Thomson Medical Pte Ltd [2017] SGCA 20 and Shaw v Kovak [2017] EWCA Civ 1028.

Purshouse, Craig

2017-11-17

In ACB v Thomson Medical Pte Ltd [2017] SGCA 20 and Shaw v Kovak [2017] EWCA Civ 1028, the idea that 'lost autonomy' should be recognised as a new form of actionable damage in the tort of negligence was rejected in Singapore and England, respectively. This, it will be argued, was the correct outcome. Protecting an interest in autonomy via the tort of negligence would undermine the coherence of that tort. In ACB, however, a new, different, form of damage was recognised: loss of 'genetic affinity'. This commentary will discuss some problems that protecting an interest in 'genetic affinity' raises before critiquing the approach to assessing damages in ACB. © The Author 2017.

Therapeutic avenues for hereditary forms of retinal blindness.

Science.gov (United States)

Kannabiran, Chitra; Mariappan, Indumathi

2018-03-01

Hereditary retinal diseases, known as retinal degenerations or dystrophies, are a large group of inherited eye disorders resulting in irreversible visual loss and blindness. They develop due to mutations in one or more genes that lead to the death of the retinal photoreceptor cells. Till date, mutations in over 200 genes are known to be associated with all different forms of retinal disorders. The enormous genetic heterogeneity of this group of diseases has posedmany challenges in understanding the mechanisms of disease and in developing suitable therapies. Therapeutic avenues that are being investigated for these disorders include gene therapy to replace the defective gene, treatment with neurotrophic factors to stimulate the growth of photoreceptors, cell replacement therapy, and prosthetic devices that can capture light and transmit electrical signals through retinal neurons to the brain. Several of these are in process of human trials in patients, and have shown safety and efficacy of the treatment. A combination of approaches that involve both gene replacement and cell replacement may be required for optimum benefit.

Vulnerability studies and integrated assessments for hazard risk reduction in Pittsburgh, PA (Invited)

Science.gov (United States)

Klima, K.

2013-12-01

Today's environmental problems stretch beyond the bounds of most academic disciplines, and thus solutions require an interdisciplinary approach. For instance, the scientific consensus is changes in the frequency and severity of many types of extreme weather events are increasing (IPCC 2012). Yet despite our efforts to reduce greenhouse gases, we continue to experience severe weather events such as Superstorm Sandy, record heat and blizzards, and droughts. These natural hazards, combined with increased vulnerability and exposure, result in longer-lasting disruptions to critical infrastructure and business continuity throughout the world. In order to protect both our lives and the economy, we must think beyond the bounds of any one discipline to include an integrated assessment of relevant work. In the wake of recent events, New York City, Washington, DC, Chicago, and a myriad of other cities have turned to their academic powerhouses for assistance in better understanding their vulnerabilities. This talk will share a case study of the state of integrated assessments and vulnerability studies of energy, transportation, water, real estate, and other main sectors in Pittsburgh, PA. Then the talk will use integrated assessment models and other vulnerability studies to create coordinated sets of climate projections for use by the many public agencies and private-sector organizations in the region.

Capturing the Material Invisible: OGS Crawford, Ghosts, and the Stonehenge Avenue

Directory of Open Access Journals (Sweden)

Martyn Barber

2016-11-01

Full Text Available Why do archaeologists excavate? What should we expect from archaeological archives? OGS Crawford’s discovery and excavation of the course of the Stonehenge Avenue in the summer of 1923 – perhaps the first time that a cropmark was identified on an aerial photograph and the first such site to be excavated, and moreover a discovery that had considerable impact on the understanding of Stonehenge’s construction and its relationship with the wider landscape – has left virtually no material trace within the relevant archives. This paper aims to offer an explanation for that absence, and to shed some light on Crawford’s belief that his excavations were unlikely to yield ‘tangible results’.

A well-posed numerical method to track isolated conformal map singularities in Hele-Shaw flow

International Nuclear Information System (INIS)

Baker, G.; Siegel, M.; Tanveer, S.

1995-01-01

We present a new numerical method for calculating an evolving 2D Hele-Shaw interface when surface tension effects are neglected. In the case where the flow is directed from the less viscous fluid into the more viscous fluid, the motion of the interface is ill-posed; small deviations in the initial condition will produce significant changes in the ensuing motion. The situation is disastrous for numerical computation, as small roundoff errors can quickly lead to large inaccuracies in the computed solution. Our method of computation is most easily formulated using a conformal map from the fluid domain into a unit disk. The method relies on analytically continuing the initial data and equations of motion into the region exterior to the disk, where the evolution problem becomes well-posed. The equations are then numerically solved in the extended domain. The presence of singularities in the conformal map outside of the disk introduces specific structures along the fluid interface. Our method can explicitly track the location of isolated pole and branch point singularities, allowing us to draw connections between the development of interfacial patterns and the motion of singularities as they approach the unit disk. In particular, we are able to relate physical features such as finger shape, side-branch formation, and competition between fingers to the nature and location of the singularities. The usefulness of this method in studying the formation of topological singularities (self-intersections of the interface) is also pointed out. 47 refs., 10 figs., 1 tab

2017-04-05

Written by a group of political science researchers, this commentary focuses on the contributions of political science to public health and proposes research avenues to increase those contributions. Despite progress, the links between researchers from these two fields develop only slowly. Divergences between the approach of political science to public policy and the expectations that public health can have about the role of political science, are often seen as an obstacle to collaboration between experts in these two areas. Thus, promising and practical research avenues are proposed along with strategies to strengthen and develop them. Considering the interdisciplinary and intersectoral nature of population health, it is important to create a critical mass of researchers interested in the health of populations and in healthy public policy that can thrive working at the junction of political science and public health. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

Finding ways to say 'yes': report of the Laurier Avenue geothermal project

International Nuclear Information System (INIS)

2010-01-01

RESCo Energy Inc. (RESCo), Booz Engineering and R. Mancini And Associates were requested by Laurier Avenue residents and the Don Vale Cabbagetown Residents Association Inc. to work together to provide an engineering study on the feasibility of using geo-exchange heating and cooling for the heritage homes in the Laurier Avenue neighbourhood. The main purpose of the analysis was to examine the potential application of geothermal heating and other energy efficiency technologies in a heritage neighbourhood in Toronto. The study was also designed to evaluate the options to preserve ground-water run-off using permeable pavement solutions during road reconstruction. Aside from the comparison between existing technologies, this project also integrates political, bureaucratic, legal and financing aspects. Baseline conditions of the homes were identified and eco-energy audits were performed on some of them. Energy efficiencies are generally low in these homes and heating systems are not appropriate. Nevertheless, utility costs are generally moderate thanks to the small size and the proximity of the houses. Although they are effective, geo-exchange systems are expensive and still difficult to implement in an urban environment. The challenges they have to face involve using city property for borefields, heritage concerns, archaeological preservation and financial aspects. The scope of the study includes other efficiency technologies such as air source heat pumps, home air sealing and insulation upgrades and high efficiency hot water systems. The potential for electricity generation using renewable energy is limited by the site conditions. Considering Toronto's ambitions regarding energy-efficiency and GHG reductions, it will be necessary to identify solutions to reduce bureaucratic barriers to citizen initiatives like the one described here.

Targeting IgG in Arthritis: Disease Pathways and Therapeutic Avenues

Full Text Available Rheumatoid arthritis (RA is a polygenic and multifactorial syndrome. Many complex immunological and genetic interactions are involved in the final outcome of the clinical disease. Autoantibodies (rheumatoid factors, anti-citrullinated peptide/protein antibodies are present in RA patients’ sera for a long time before the onset of clinical disease. Prior to arthritis onset, in the autoantibody response, epitope spreading, avidity maturation, and changes towards a pro-inflammatory Fc glycosylation phenotype occurs. Genetic association of epitope specific autoantibody responses and the induction of inflammation dependent and independent changes in the cartilage by pathogenic autoantibodies emphasize the crucial contribution of antibody-initiated inflammation in RA development. Targeting IgG by glyco-engineering, bacterial enzymes to specifically cleave IgG/alter N-linked Fc-glycans at Asn 297 or blocking the downstream effector pathways offers new avenues to develop novel therapeutics for arthritis treatment.

This study examined the effects of testosterone (T on the contractile properties of two sexually dimorphic forelimb muscles and one non-dimorphic muscle in male bullfrogs (Rana catesbeiana, Shaw 1802. The dimorphic muscles in castrated males with testosterone replacement (T+ achieved higher forces and lower fatigability than did castrated males without replaced testosterone (T0 males, but the magnitude of the differences was low and many of the pair-wise comparisons of each muscle property were not statistically significant. However, when taken as a whole, the means of seven contractile properties varied in the directions expected of masculine values in T+ animals in the sexually dimorphic muscles. Moreover, these data, compared with previous data on male and female bullfrogs, show that values for T+ males are similar to normal males and are significantly different from females. The T0 males tended to be intermediate in character between T+ males and females, generally retaining masculine values. This suggests that the exposure of young males to T in their first breeding season produces a masculinizing effect on the sexually dimorphic muscles that is not reversed between breeding seasons when T levels are low. The relatively minor differences in contractile properties between T+ and T0 males may indicate that as circulating T levels rise during breeding season in normal males, contractile properties can be enhanced rapidly to maximal functional levels for breeding success.

Building America Case Study: High-Velocity Small-Diameter Duct System, Pittsburgh, Pennsylvania

Energy Technology Data Exchange (ETDEWEB)

2017-04-01

This study tests the performance of a variable airflow small-diameter duct heating, ventilation, and air conditioning (HVAC) system in a new construction unoccupied low-load test house in Pittsburgh, Pennsylvania. The duct system was installed entirely in conditioned space and was operated from the winter through summer seasons. Measurements were collected on the in-room temperatures and energy consumed by the air handler and heat pump unit. Operation modes with three different volumes of airflow were compared to determine the ideal airflow scenario that maximizes room-to-room thermal uniformity while minimizing fan energy consumption. Black felt infrared imagery was used as a measure of diffuser throw and in-room air mixing. Measured results indicate the small-diameter, high velocity airflow system can provide comfort under some conditions. Solar heat gains resulted in southern rooms drifting beyond acceptable temperature limits. Insufficient airflow to some bedrooms also resulted in periods of potential discomfort. Homebuilders or HVAC contractors can use these results to assess whether this space conditioning strategy is an attractive alternative to a traditional duct system. The team performed a cost analysis of two duct system configurations: (1) a conventional diameter and velocity duct system, and (2) the small-diameter duct system. This work applies to both new and retrofit homes that have achieved a low heating and cooling density either by energy conservation or by operation in a mild climate with few heating or cooling degree days. Guidance is provided on cost trade-offs between the conventional duct system and the small-diameter duct system.

Evacuation is the protective action most often recommended in response to chemical releases in the United States. The appropriateness of a decision to evacuate depends on whether the affected areas can be cleared of residents before it is contaminated by the chemical release. In determining whether an evacuation can be completed in time, emergency officials must consider both technical and behavioral aspects. The technical components can be readily conceived and quantified. In contrast, the behavioral components are much more abstract and more difficult to estimate. This report summarizes the univariate analysis of responses to surveys conducted in two communities where evacuation was recommended following train derailments involving hazardous chemicals. The surveys were designed to identify the actions taken by residents upon receiving the emergency warning; determine when people received the warning, decided to take action, and implemented the action; and ascertain factors that might explain the nature and timing of their actions. The surveys were conducted in the Bloomfield section of Pittsburgh, Pennsylvania, and in the town of Confluence, Pennsylvania. The study confirms that compliance with an emergency warning to evacuate varies and that potentially dangerous delays can be expected. Significant differences were noted, however, in the rate and speed of compliance in the two communities. The surveys provide information on several factors that may be useful in determining the reasons for differences in the responses from the two communities as well as differences among individual respondents. Such factors include the time of day when the accident occurred, where the respondent was at the time, whether the family was together, previous disaster experience, pet ownership, the content of the warning message, and demographic characteristics. 4 refs., 4 figs., 18 tabs.

GIS-Based Planning and Modeling for Renewable Energy: Challenges and Future Research Avenues

Directory of Open Access Journals (Sweden)

Bernd Resch

2014-05-01

Full Text Available In the face of the broad political call for an “energy turnaround”, we are currently witnessing three essential trends with regard to energy infrastructure planning, energy generation and storage: from planned production towards fluctuating production on the basis of renewable energy sources, from centralized generation towards decentralized generation and from expensive energy carriers towards cost-free energy carriers. These changes necessitate considerable modifications of the energy infrastructure. Even though most of these modifications are inherently motivated by geospatial questions and challenges, the integration of energy system models and Geographic Information Systems (GIS is still in its infancy. This paper analyzes the shortcomings of previous approaches in using GIS in renewable energy-related projects, extracts distinct challenges from these previous efforts and, finally, defines a set of core future research avenues for GIS-based energy infrastructure planning with a focus on the use of renewable energy. These future research avenues comprise the availability base data and their “geospatial awareness”, the development of a generic and unified data model, the usage of volunteered geographic information (VGI and crowdsourced data in analysis processes, the integration of 3D building models and 3D data analysis, the incorporation of network topologies into GIS, the harmonization of the heterogeneous views on aggregation issues in the fields of energy and GIS, fine-grained energy demand estimation from freely-available data sources, decentralized storage facility planning, the investigation of GIS-based public participation mechanisms, the transition from purely structural to operational planning, data privacy aspects and, finally, the development of a new dynamic power market design.

As part of an ongoing effort to link the success rate of palaeointensity experiments to specific rock magnetic properties, we present new palaeointensity results from basaltic lavas erupted in 1951 and 1995 on the island of Fogo, Cape Verde. Both Thellier and LTD-DHT Shaw palaeointensity experiments were used to estimate the historical field strength. The intensity of the field during these eruptions is constrained by data from the Mbour geomagnetic observatory (Senegal) and IGRF10. In 1951, the magnetic field intensity at Fogo was approximately 33.8 µT during the eruption of three distinct surface flows, covering approximately 14 km2. The field intensity was approximately 32.5 µT during a 1995 eruption of one large flow that extends 4 km2 across the caldera floor. Different volcanic textures were sampled from multiple sites within both the 1951 and 1995 lava flows, including glass-rich pahoehoe and aa flows, highly vesicular flows, and massive non-vesicular lava. Detailed rock magnetic measurements demonstrate that each site and texture displays distinctively different rock magnetic properties. We assess possible links between the outcome of the Thellier and LTD-DHT palaeointensity experiments and the distribution of magnetic domain states, average oxidation state, and laboratory induced alteration.

Malaria remains a global health problem affecting more than 515 million people all over the world including Malaysia. It is on the rise, even within unknown regions that previous to this were free of malaria. Although malaria eradication programs carried out by vector control programs are still effective, anti-malarial drugs are also used extensively for curtailing this disease. But resistance to the use of anti-malarial drugs is also increasing on a daily basis. With an increased understanding of mechanisms that cause growth, differentiation and development of malarial parasites in rodents and humans, new avenues of therapeutic approaches for controlling the growth, synchronization and development of malarial parasites are essential. Within this context, the recent discoveries related to IP3 interconnected signalling pathways, the release of Ca2+ from intracellular stores of Plasmodium, ubiquitin protease systems as a signalling pathway, and melatonin influencing the growth and differentiation of malarial parasites by its effects on these signalling pathways have opened new therapeutic avenues for arresting the growth and differentiation of malarial parasites. Indeed, the use of melatonin antagonist, luzindole, has inhibited the melatonin's effect on these signalling pathways and thereby has effectively reduced the growth and differentiation of malarial parasites. As Plasmodium has effective sensors which detect the nocturnal plasma melatonin concentrations, suppression of plasma melatonin levels with the use of bright light during the night or by anti-melatonergic drugs and by using anti-kinase drugs will help in eradicating malaria on a global level. A number of patients have been admitted with regards to the control and management of malarial growth. Patents related to the discovery of serpentine receptors on Plasmodium, essential for modulating intra parasitic melatonin levels, procedures for effective delivery of bright light to suppress plasma melatonin

In this work, we develop a numerical model to explain the lab scale experimental setup [1] modeling the aerofractures in a porous medium. The mentioned experimental setup consists in a rectangular Hele-Shaw cell with three closed boundaries and one semi-permeable boundary which enables the flow of the fluid but not the solid particles. During the experiments, the fluid (pressurized air) is injected into the system with a constant injection pressure from the point opposite to the semi-permeable boundary. At the large enough injection pressures, the fluid also displaces grains (80 μm grain size) and creates channels and fractures towards the semi-permeable boundary. This analogue model is developed in a linear geometry, with confinement and at a lower porosity to study the instabilities developing during the fast motion of a fluid in dense porous materials: fracturing, fingering, and channeling. Different sources of the signal (air vibration in the carved area, changes in the effective stress due to fluid-solid interactions [2]) are separately analyzed and are investigated further using a far field approximation of Lamb waves presented by Goyder & White [3]. In the analysis phase, power spectrum of different timewindows (5 ms) obtained from the recorded signal are computed. Then, the evolution of this power spectrum is compared with the experimental findings. In the power spectrum, it is possible to see some characteristic structure like peaks in specific frequency ranges. These "peaks" are strongly influenced by the size and branching of the channels, compaction of the medium, vibration of air in the pores and the fundamental frequency of the plate. We found that, in the synthetic dataset, the peaks in the low frequency range (f Daniel G, Flekkøy EG, Måløy KJ.

Meningiomas are the most common intracranial tumors. Diagnosis by MRI is generally straightforward, but lack of imaging specificity can present a diagnostic dilemma, particularly in patients with cancer. We report our experience with meningioma identification on Pittsburgh compound B (PiB) PET/CT. Patients who underwent PiB PET/CT from 2006 to 2015 were reviewed to identify those with intracranial tumors. Tumor types were classified by MR appearance, or by pathology when available. Maximum standardized uptake value (SUVmax) measurements of tumor PiB activity were compared across tumor types. 2472 patients underwent PiB PET/CT in the period of interest; 45 patients (1.8%) had probable or definite intracranial tumor. Tumor types were meningioma (29/45, 64%), vestibular schwannoma (7/45, 16%), pituitary macroadenoma (4/45, 9%), metastatic disease (2/45, 4%), and others (3/45, 7%). In patients with meningioma, the mean lesion SUVmax was 2.05 (SD 1.37), versus 1.00 (SD 0.42) in patients with non-meningioma tumors (p < 0.01). A receiver operating curve was created for lesion:cerebellum SUVmax ratio, with an area under the curve of 0.91 for a value of 1.68. At or above this ratio, specificity for meningioma was 100% (95% CI 79-100%) and sensitivity was 76% (95% CI 57-90%). PiB PET activity within an intracranial tumor is a highly specific and reasonably sensitive marker of meningioma. Further prospective evaluation is warranted to validate this result as well as to assess the performance of commercially available beta-amyloid radiotracers in meningioma identification.

Effect of Using an Indoor Air Quality Sensor on Perceptions of and Behaviors Toward Air Pollution (Pittsburgh Empowerment Library Study): Online Survey and Interviews.

2018-03-08

Air quality affects us all and is a rapidly growing concern in the 21st century. We spend the majority of our lives indoors and can be exposed to a number of pollutants smaller than 2.5 microns (particulate matter, PM 2.5 ) resulting in detrimental health effects. Indoor air quality sensors have the potential to provide people with the information they need to understand their risk and take steps to reduce their exposure. One such sensor is the Speck sensor developed at the Community Robotics, Education and Technology Empowerment Lab at Carnegie Mellon University. This sensor provides users with continuous real-time and historical PM 2.5 information, a Web-based platform where people can track their PM 2.5 levels over time and learn about ways to reduce their exposure, and a venue (blog post) for the user community to exchange information. Little is known about how the use of such monitors affects people's knowledge, attitudes, and behaviors with respect to indoor air pollution. The aim of this study was to assess whether using the sensor changes what people know and do about indoor air pollution. We conducted 2 studies. In the first study, we recruited 276 Pittsburgh residents online and through local branches of the Carnegie Library of Pittsburgh, where the Speck sensor was made available by the researchers in the library catalog. Participants completed a 10- to 15-min survey on air pollution knowledge (its health impact, sources, and mitigation options), perceptions of indoor air quality, confidence in mitigation, current behaviors toward air quality, and personal empowerment and creativity in the spring and summer of 2016. In our second study, we surveyed 26 Pittsburgh residents in summer 2016 who checked out the Speck sensor for 3 weeks on the same measures assessed in the first study, with additional questions about the perception and use of the sensor. Follow-up interviews were conducted with a subset of those who used the Speck sensor. A series of paired t

In the present study, the concentration and distribution of Ba, Cu, Mo, Pb, S, Zn and Zr in soils collected along two main avenues (Pinheiros River Highway and Tiete River Highway) with high traffic density in the metropolitan region of Sao Paulo, Brazil, are presented, and their possible sources are discussed. These elements are strongly considered as contaminants originated from vehicular emissions. The analytical technique employed was XRF. The data set was evaluated by a t test for independent samples (group: avenues) at a 0.05 significance level. According to t test, the average contents obtained from Pinheiros River Highways are significantly different than the Tiete River, except for Mo. Multivariate statistic approaches (Pearson Correlation, Cluster and Factorial Analysis - FA) were adopted for data treatment. FA identified two main factors which accounted for about 86% of the total variance. The behavior of Ba, Cu, Pb, S and Zn were explained by the Factor 1. This indicates that the elements may have similar sources, probably related to gas emissions escaping from the vehicle fuel system. Factor 2 included Mo and Zr, suggesting their origin in the sample soils may be associated with the deterioration process of some device in the vehicular engine system or may be associated with the chemical composition of the urban soil analyzed.

Reduced binding of Pittsburgh Compound-B in areas of white matter hyperintensities

Directory of Open Access Journals (Sweden)

A.E. Goodheart

2015-01-01

Full Text Available The amyloid imaging agent, Pittsburgh Compound-B, binds with high affinity to β-amyloid (Aβ in the brain, and it is well established that PiB also shows non-specific retention in white matter (WM. However, little is known about retention of PiB in areas of white matter hyperintensities (WMH, abnormalities commonly seen in older adults. Further, it is hypothesized that WMH are related to both cognitive dysfunction and Aβ deposition. The goal of the present study was to explore PiB retention in both normal-appearing WM (NAWM and WMH in a group of elderly, cognitively normal individuals. In a group of cognitively normal elderly (n = 64; 86.5 ± 2.6 years two analyses were applied: (1 ROIs were placed over periventricular areas in which WMH caps are commonly seen on all subjects, regardless of WMH burden or size. (2 Subject-specific maps of NAWM and WMH were co-registered with the PiB-PET images and mean SUVR values were calculated in these NAWM and WMH maps. PiB retention was significantly reduced in the ROIs of subjects with high WMH compared to subjects with low WMH. Additionally, in subjects with high WMH, there was significantly lower PiB retention in subject-specific maps of WMH compared to NAWM, which was not observed in subjects with low WMH, likely because of the small size of WMH maps in this group. These data suggest that WM in areas of WMH binds PiB less effectively than does normal WM. Further exploration of this phenomenon may lead to insights about the molecular basis of the non-specific retention of amyloid tracers in white matter.

Update on novel targets and potential treatment avenues in pulmonary hypertension

Huetsch, John C.; Suresh, Karthik; Bernier, Meghan

2016-01-01

Pulmonary hypertension (PH) is a condition marked by a combination of constriction and remodeling within the pulmonary vasculature. It remains a disease without a cure, as current treatments were developed with a focus on vasodilatory properties but do not reverse the remodeling component. Numerous recent advances have been made in the understanding of cellular processes that drive pathologic remodeling in each layer of the vessel wall as well as the accompanying maladaptive changes in the right ventricle. In particular, the past few years have yielded much improved insight into the pathways that contribute to altered metabolism, mitochondrial function, and reactive oxygen species signaling and how these pathways promote the proproliferative, promigratory, and antiapoptotic phenotype of the vasculature during PH. Additionally, there have been significant advances in numerous other pathways linked to PH pathogenesis, such as sex hormones and perivascular inflammation. Novel insights into cellular pathology have suggested new avenues for the development of both biomarkers and therapies that will hopefully bring us closer to the elusive goal: a therapy leading to reversal of disease.

There is growing interest in white matter (WM) imaging with positron emission tomography (PET). We studied the association of cognitive function in late multiple sclerosis (MS) with cortical and WM Pittsburgh compound-B PET (PiB-PET) binding. In the population-based Mayo Clinic Study of Aging, 24 of 4869 participants had MS (12 underwent PiB-PET). Controls were age and sex matched (5:1). We used automated or semi-automated processing for quantitative image analyses and conditional logistic regression for group differences. MS patients had lower memory ( p = 0.03) and language ( p = 0.02) performance; smaller thalamic volumes ( p = 0.003); and thinner temporal ( p = 0.001) and frontal ( p = 0.045) cortices on magnetic resonance imaging (MRI) than controls. There was no difference in global cortical PiB standardized uptake value ratios between MS and controls ( p = 0.35). PiB uptake was lower in areas of WM hyperintensities compared to normal-appearing white matter (NAWM) in MS ( p = 0.0002). Reduced PiB uptake in both the areas of WM hyperintensities ( r = 0.65; p = 0.02) and NAWM ( r = 0.69; p = 0.01) was associated with decreased visuospatial performance in MS. PiB uptake in the cortex in late MS is not different from normal age-matched controls. PiB uptake in the WM in late MS may be a marker of the large network structures' integrity such as those involved in visuospatial performance.

Results of the radiological survey at 146 W. Central Avenue, Maywood, New Jersey (MJ034)

1989-11-01

Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and reining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from OaK Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Th, derived from the MCW site. These surveys typically include direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, a private property at 146 West Central Avenue, Maywood, New Jersey (MJ034), was conducted during 1987 and 1988. While some measurements at this property were greater than background levels typically encountered in the New jersey area, no radiation levels nor radionuclide concentrations exceeded the guidelines established by the DOE for the Maywood, New Jersey, area remedial action plan. However, because of the proximity of the railroad property, which will be remediated, and the DOE's ALARA (As Low As Reasonably Achievable) policy, concurrent removal of the slightly elevated soil layers at 146 W. Central Avenue may be justified. 6 refs., 6 figs., 3 tabs

Full Text Available Biotechnology is expected to be a great technological revolution followed by information technology. It is an application of scientific and engineering principles to the processing of material by biological agents to provide better goods and services to mankind. Commercially its techniques are applied long back in 6 th century in the art of brewing, wine making and baking. It has progressed there after crossing different land marks. Modern biotechnology has developed significantly in the late 19 th century with groundbreaking discoveries applicable in medicine, food, agriculture, chemistry, environmental protection and many more industries. It is widely used in the development of high-yielding, disease-resistant, better quality varieties by applying tissue culture and recombinant DNA techniques. It has wide application in animal breeding using techniques such as artificial insemination, in vitro fertilization and embryo transfer. Specific enzymes used in laundry, fuel and leather industries for better quality, economically feasible and environmental friendly production. Biotechnology in healthcare system uses body′s own tools and weapons to fight against diseases, manufacturing of targeted therapeutic proteins, gene therapy and so on. Novel approaches such as proteomics and structural biology are contributing to understanding the chemistry of life and diseases. Malfunctioning gene replaced with correctly functioning gene by using gene therapy. Tissue engineering has opened up the use of in vitro developed tissue or organ in repairing wounded tissue and system biology which is a computer-based approach to understand cell functions. Although every new discovery related to biology and its implications is significant and has taken the technology ahead. This includes applications, commercialization, controversies, media exposure and so on. Hence, we have enlisted some of the chronological development avenues in biotechnology across the world.

Paradoxical thinking as a new avenue of intervention to promote peace.

In societies involved in an intractable conflict, there are strong socio-psychological barriers that contribute to the continuation and intractability of the conflict. Based on a unique field study conducted in the context of the Israeli-Palestinian conflict, we offer a new avenue to overcome these barriers by exposing participants to a long-term paradoxical intervention campaign expressing extreme ideas that are congruent with the shared ethos of conflict. Results show that the intervention, although counterintuitive, led participants to express more conciliatory attitudes regarding the conflict, particularly among participants with center and right political orientation. Most importantly, the intervention even influenced participants' actual voting patterns in the 2013 Israeli general elections: Participants who were exposed to the paradoxical intervention, which took place in proximity to the general elections, reported that they tended to vote more for dovish parties, which advocate a peaceful resolution to the conflict. These effects were long lasting, as the participants in the intervention condition expressed more conciliatory attitudes when they were reassessed 1 y after the intervention. Based on these results, we propose a new layer to the general theory of persuasion based on the concept of paradoxical thinking.

Tyagi, Purnima; Sharma, P K; Kothari, S L

2010-01-01

In this chapter, we describe multiplication of the superior and elite tree of Crataeva adansonii using plant tissue culture techniques. An ornamental and avenue tree, it is not available in abundance because of poor seed germination and seedling establishment. It reproduces in nature by root suckers, but that restricts its distribution to very limited areas. Efficient procedures are outlined for plant regeneration through direct shoot bud formation, indirect organogenesis, and somatic embryogenesis through callus formation. Different explants were utilized for separate pathways of regeneration. Murashige and Skoog's (MS) medium containing 3 mg/L BA and 0.05-0.1 mg/L NAA is most effective in direct induction of axillary buds from nodal explants and shoot tips. Adventitious shoots developed from leaves on MS medium containing 3 mg/L BA and 0.1 mg/L NAA. De novo shoots were obtained from the anthers on MS medium supplemented with 3 mg/L BA. Somatic embryos developed on half strength MS medium containing 0.1 mg/L 2, 4-D. Roots were induced at the cut ends of shoots on MS basal medium devoid of growth regulators. The plantlets were then transferred to pots.

Repopulating Decellularized Kidney Scaffolds: An Avenue for Ex Vivo Organ Generation

Directory of Open Access Journals (Sweden)

Robert A. McKee

2016-03-01

Full Text Available Recent research has shown that fully developed organs can be decellularized, resulting in a complex scaffold and extracellular matrix (ECM network capable of being populated with other cells. This work has resulted in a growing field in bioengineering focused on the isolation, characterization, and modification of organ derived acellular scaffolds and their potential to sustain and interact with new cell populations, a process termed reseeding. In this review, we cover contemporary advancements in the bioengineering of kidney scaffolds including novel work showing that reseeded donor scaffolds can be transplanted and can function in recipients using animal models. Several major areas of the field are taken into consideration, including the decellularization process, characterization of acellular and reseeded scaffolds, culture conditions, and cell sources. Finally, we discuss future avenues based on the advent of 3D bioprinting and recent developments in kidney organoid cultures as well as animal models of renal genesis. The ongoing mergers and collaborations between these fields hold the potential to produce functional kidneys that can be generated ex vivo and utilized for kidney transplantations in patients suffering with renal disease.

Belo Horizonte is the sixth most populous city in Brazil, has the third largest fleet of vehicles and it is close to large mineralogical reserves, such the Quadrilátero Ferrífero. These factors, coupled with the industrial growth and civil construction, raise questions about society regarding ambient air quality. A historically problematic contaminant is the particulate matter (PM), a mixture of solid and liquid particles in suspension that generate environmental damage and human health. These particles can cause from a simple infection to death, being their dimension a fundamental factor to evaluate the impact caused. In this context, this research investigated the air quality due to PM10 (particles less than 10 microns) in a high traffic flow of Minas Gerais capital, Presidente Antônio Carlos Avenue. This avenue is one of the main accesses to the region of Pampulha, an area of great tourist and sporting relevance of the city and has undergone works of duplication and implementation of exclusive lanes for public transport buses due to the realization of the 2014 World Cup. Involved monitoring in the avenue in the year 2014 in order to collect the PM10 present in the ambient air. The characterization of PM10 occurred with the use of the X-ray diffraction technique, one of the main tools of mineralogical characterization, due to its simplicity, speed and reliability of the obtained results. The minerals detected by the analysis were evaluated for their possible origin, generating information for the evaluation of PM10 emitting sources that are fundamental for the management of air quality in the city.

Economic impact and policy implications from urban shared transportation: The case of Pittsburgh's shared bike system.

Science.gov (United States)

Pelechrinis, Konstantinos; Zacharias, Christos; Kokkodis, Marios; Lappas, Theodoros

2017-01-01

During the last years the number of cities that have installed and started operating shared bike systems has significantly increased. These systems provide an alternative and sustainable mean of transportation to the city dwellers. Apart from the energy sustainability benefits, shared bike systems can have a positive effect on residents' health, air quality and the overall condition of the currently crumbling road network infrastructure. Anecdotal stories and survey studies have also identified that bike lanes have a positive impact on local businesses. In this study, driven by the rapid adoption of shared bike systems by city governments and their potential positive effects on a number of urban life facets we opt to study and quantify the value of these systems. We focus on a specific aspect of this value and use evidence from the real estate market in the city of Pittsburgh to analyze the effect on dwellers' properties of the shared bike system installed in the city in June 2015. We use quasi-experimental techniques and find that the shared bike system led to an increase in the housing prices (both sales and rental prices) in the zip codes where shared bike stations were installed. We further bring into the light potential negative consequences of this impact (i.e., gentrification) and discuss/propose two public policies that can exploit the impact of the system for the benefit of both the local government as well as the city dwellers.

Full Text Available Objective: Sleep disturbances play a fundamental role in the pathophysiology posttraumatic stress disorder (PTSD, and are not only a secondary feature. The aim of this study was to validate and assess the psychometric properties of the Brazilian version of the Pittsburgh Sleep Quality Index Addendum for PTSD (PSQI-A-BR, a self-report instrument designed to assess the frequency of seven disruptive nocturnal behaviors, in a sample of participants with and without PTSD. Methods: PSQI-A was translated into Brazilian Portuguese and applied to a convenience sample of 190 volunteers, with and without PTSD, who had sought treatment for the consequences of a traumatic event. Results: The PSQI-A-BR displayed satisfactory internal consistency (Cronbach's coefficient of 0.83 between all items and convergent validity with the Clinician Administered PTSD Scale (CAPS, even when excluding sleep-related items (r = 0.52. Test-retest yielded high agreement in the global PSQI-A-BR, with good stability over time (r = 0.88. A global PSQI-A-BR cutoff score of 7 yielded a sensitivity of 79%, specificity of 64%, and a global score of 7 yielded a positive predictive value of 93% for discriminating participants with PTSD from those without PTSD. Conclusion: The PSQI-A-BR is a valid instrument for PTSD assessment, applicable to both clinical and research settings.

Assisted suicide and the killing of people? Maybe. Physician-assisted suicide and the killing of patients? No: the rejection of Shaw's new perspective on euthanasia.

Science.gov (United States)

McLachlan, Hugh V

2010-05-01

David Shaw presents a new argument to support the old claim that there is not a significant moral difference between killing and letting die and, by implication, between active and passive euthanasia. He concludes that doctors should not make a distinction between them. However, whether or not killing and letting die are morally equivalent is not as important a question as he suggests. One can justify legal distinctions on non-moral grounds. One might oppose physician-assisted suicide and active euthanasia when performed by doctors on patients whether or not one is in favour of the legalisation of assisted suicide and active euthanasia. Furthermore, one can consider particular actions to be contrary to appropriate professional conduct even in the absence of legal and ethical objections to them. Someone who wants to die might want only a doctor to kill him or to help him to kill himself. However, we are not entitled to everything that we want in life or death. A doctor cannot always fittingly provide all that a patient wants or needs. It is appropriate that doctors provide their expert advice with regard to the performance of active euthanasia but they can and should do so while, qua doctors, they remain hors de combat.

2016-12-01

Retinopathy of prematurity (ROP) is a multifactorial disease and the main cause of visual impairment and blindness in premature neonates. The inner retina has been considered the primary region affected in ROP, but choroidal vascular degeneration and progressive outer retinal dysfunctions have also been observed. This review focuses on observations regarding neurovascular dysfunctions in both the inner and outer immature retina, the mechanisms and the neuronal-derived factors implicated in the development of ROP, as well potential therapeutic avenues for this disorder. Alterations in the neurovascular integrity of the inner and outer retina contribute to the development of ROP. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Microwave Palaeointensity Experiments On Terrestrial and Martian Material

Shaw, J.; Hill, M.; Gratton, M.

The microwave palaeointensity technique was developed in Liverpool University (Walton et al 1996) and has successfully been applied to archaeological ceramics and recent lavas (Shaw et al 1996, 1999.; Hill et al 1999,2000). These published results show that microwave analysis provides accurate palaeointensity determinations com- bined with a very high success rate. Most recently the technique has been successfully applied to Martian material (Shaw et al, 2001) to look for the existence of an internal Martian dynamo early in Martian history. New experiments have been carried out us- ing microwaves to demagnetise synthetic muti-component TRM's and new palaeoin- tensity experiments providing a comparison between microwave analysis of laboratory TRM's and conventional thermal Thellier analysis of microwave generated mTRM's. These experiments demonstrate the equivalence of microwave and thermally gener- ated TRM's. D. Walton, S Snape, T.C. Rolph, J. Shaw and J.A.

Invited commentary: Personality phenotype and mortality--new avenues in genetic, social, and clinical epidemiology.

Science.gov (United States)

Chapman, Benjamin P

2013-09-01

In this issue of the Journal, Jokela et al. (Am J Epidemiol. 2013;178(5):667-675) scrutinize the association between personality phenotype and all-cause mortality in remarkable detail by using an "individual-participant meta-analysis" design. Across 7 large cohorts varying in demographics and methods of personality measurement, they find varying prospective associations for 4 dimensions of the five-factor (or "Big Five") model of personality, but robust and consistent prospective associations for Big Five dimension of "conscientiousness." Jokela et al. place an important exclamation point on a long era of study of this topic and hint directly and indirectly at new avenues for this line of research. I consider the following 3 areas particularly rife for further inquiry: the role of genetics in personality and health studies; the role of personality in social inequalities in health; and the health policy and clinical implications of work like that of Jokela et al., including the potential role of personality phenotype in the evolution of personalized medicine.

Lost in translation. New unexplored avenues for neuropsychopharmacology: epigenetics and microRNAs.

Science.gov (United States)

Tardito, Daniela; Mallei, Alessandra; Popoli, Maurizio

2013-02-01

Mood and anxiety disorders are among the major causes of disability worldwide. Despite clear need for better therapies, efforts to develop novel drugs have been relatively unsuccessful. One major reason is lack of translation into neuropsychopharmacology of the impressive recent array of knowledge accrued by clinical and preclinical researches on the brain. Here focus is on epigenetics mechanisms, including microRNAs, which seem particularly promising for the identification of new targets for alternative pharmacological approaches. First, the current knowledge about epigenetic mechanisms, including DNA methylation, posttranslational modification of histone proteins, focusing on histone methylation and acetylation, and posttranscriptional modulation of gene expression by microRNAs is described. Then evidence showing involvement of epigenetics and microRNAs in the pathophysiology of mood and anxiety disorders as well as evidence showing that some of the currently employed antidepressants and mood stabilizers also affect epigenetic and microRNA mechanisms are reviewed. Finally current evidence and novel approaches in favor of drugs regulating epigenetic and microRNA mechanisms as potential therapeutics for these disorders are discussed. Although still in its infancy, research investigating the effects of pharmacological modulation of epigenetic and microRNA mechanisms in neuropsychiatric disorders continues to provide encouraging findings, suggesting new avenues for treatment of mood and anxiety disorders.

1989-11-01

Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Th, derived from the MCW site. The surveys typically include direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this commercial property at Route 17(S) and Becker Avenue, Rochelle Park, New Jersey (RJ001), was conducted in 1986. Measurements taken at the commercial property located at Route 17(S) and Becker Avenue indicate slightly elevated gamma exposure rates in three areas of the parking lot. Although results of analysis of the asphalt disclosed radionuclide concentrations in excess of the applicable criterion, their presence is due to naturally radioactive substances in asphalt patching materials and is not associated with material from the MCW site. Therefore, it is recommended that this site be eliminated from consideration for inclusion in the DOE remedial action program. 5 refs., 2 figs., 3 tabs

Full Text Available Goniothalamus velutinus Airy Shaw belongs to the family Annonaceae which is known to have anticancer, antitumor and many other bioactivities. Natives of Sabah and Sarawak use root decoction of G. velutinus for the treatment of headache and food poisoning while the bark was used as a mosquito repellent. Bark and leaf extracts of this plant, obtained from Brunei Darussalam, were tested for phytochemical and antioxidant activities. Phytochemical screening of plant extracts revealed the presence of alkaloids, steroids, terpenoids and cardiac glycosides. Quantitative determination of total phenolics, total flavonoids, and various in vitro antioxidant activities (DPPH, ABTS and FRAP of methanolic extract was carried out using colorimetric methods. The total phenolic content, expressed as mg of gallic acid equivalent (GAE per gram of extract, was found to be 68 mg GAE/g and 78 mg GAE/g for bark and leaves respectively. The radical scavenging activity measurement, expressed in terms of EC50 (effective concentration of extract in μg/mL that reduces DPPH absorbance to 50% as compared to negative control, for leaf and bark extracts was found to be 155 μg/mL and 204 μg/mL respectively. Standards trolox and ascorbic acid show EC50 value of 5 μg/mL and 4 μg/mL respectively. Trolox equivalent antioxidant capacity (TEAC was measured using the ABTS and FRAP method. Result for bark and leaf extracts was 79 mg and 106 mg trolox equivalent (TE/g respectively for the ABTS method. For FRAP assay, results for bark and leaf extracts were 80 and 89 mg TE/g respectively.

G protein-coupled receptors (GPCRs) are the largest family of cell surface receptors and a key drug target class. Recently, allosteric drugs that can co-bind with and modulate the activity of the endogenous ligand(s) for the receptor have become a major focus of the pharmaceutical and biotechnology industry for the development of novel GPCR therapeutic agents. This class of drugs has distinct properties compared with drugs targeting the endogenous (orthosteric) ligand-binding site that include the ability to sculpt cellular signaling and to respond differently in the presence of discrete orthosteric ligands, a behavior termed "probe dependence." Here, using cell signaling assays combined with ex vivo and in vivo studies of insulin secretion, we demonstrate that allosteric ligands can cause marked potentiation of previously "inert" metabolic products of neurotransmitters and peptide hormones, a novel consequence of the phenomenon of probe dependence. Indeed, at the muscarinic M(2) receptor and glucagon-like peptide 1 (GLP-1) receptor, allosteric potentiation of the metabolites, choline and GLP-1(9-36)NH(2), respectively, was ~100-fold and up to 200-fold greater than that seen with the physiological signaling molecules acetylcholine and GLP-1(7-36)NH(2). Modulation of GLP-1(9-36)NH(2) was also demonstrated in ex vivo and in vivo assays of insulin secretion. This work opens up new avenues for allosteric drug discovery by directly targeting modulation of metabolites, but it also identifies a behavior that could contribute to unexpected clinical outcomes if interaction of allosteric drugs with metabolites is not part of their preclinical assessment.

A radiological survey of the commercial property at 7 Malcolm Avenue, Teterboro, New Jersey, was conducted on November 12--20, 1986. Samples of the soil surface were taken for further analyses during this time. Conversations with property owners revealed that originally this site was part of a single property of approximately 107 acres owned entirely by the Bendix Aerospace Corporation. During this period of total property ownership, Bendix was licensed by the Nuclear Regulatory Commission to use thorium in on-site Navy/Bendix process. Around 1976, the property was subdivided into three parcels, and one parcel of about 7 acres was purchased by Sumitomo Corporation. 5 refs., 3 figs., 5 tabs

Using New Mode Choice Model Nesting Structures to Address Emerging Policy Questions: A Case Study of the Pittsburgh Central Business District

Full Text Available As transportation activities affect a region’s environmental quality, knowing why individuals prefer certain modes can help a region make judicious transportation investments. Using a nested logit model, this paper studies the behavior of commuters to downtown Pittsburgh who use auto, bus, light rail, walking, and biking. Although statistical measures influence the selection of a nesting structure, another criterion for model selection is the policy questions such models inform. Hence this paper demonstrates how an alternative model structure allows planners to consider new policy questions. For example, how might a change in parking fee affect greenhouse gas emission (GHGs? The proposed model showed that a 5%, 10% and 15% increase in parking cost reduces GHGs by 7.3%, 9% and 13.2%, respectively, through increasing carpoolers’ mode share. Because the proposed model forecasts mode choices of certain groups of travelers with higher accuracy (compared to an older model that did not consider the model selection criteria presented here, the proposed model strengthens policymakers’ ability to consider environmental impacts of interest to the region (in this case, GHGs. The paper does not suggest that one nesting structure is always preferable; rather the nesting structure must be chosen with the policy considerations in mind.

Excess sediment in rivers and estuaries poses serious environmental and economic challenges. The U.S. Army Corps of Engineers (USACE) routinely dredges sediment in Federal navigation channels to maintain commercial shipping operations. The USACE initiated a 3-year pilot project in 2013 to use navigation channel dredged material to aid in restoration of shoreline habitat in the 21st Avenue West Channel Embayment of the Duluth-Superior Harbor. Placing dredged material in the 21st Avenue West Channel Embayment supports the restoration of shallow bay aquatic habitat aiding in the delisting of the St. Louis River Estuary Area of Concern.The U.S. Geological Survey, in cooperation with the USACE, collected turbidity and suspended-sediment concentrations (SSCs) in 2014 and 2015 to measure the horizontal and vertical distribution of SSCs during placement operations of dredged materials. These data were collected to help the USACE evaluate the use of several best management practices, including various dredge material placement techniques and a silt curtain, to mitigate the dispersion of suspended sediment.Three-dimensional visualization maps are a valuable tool for assessing the spatial displacement of SSCs. Data collection was designed to coincide with four dredged placement configurations that included periods with and without a silt curtain as well as before and after placement of dredged materials. Approximately 230 SSC samples and corresponding turbidity values collected in 2014 and 2015 were used to develop a simple linear regression model between SSC and turbidity. Using the simple linear regression model, SSCs were estimated for approximately 3,000 turbidity values at approximately 100 sampling sites in the 21st Avenue West Channel Embayment of the Duluth-Superior Harbor. The estimated SSCs served as input for development of 12 three-dimensional visualization maps.

Purification and Phytotoxic Analysis of Botrytis cinerea Virulence Factors: New Avenues for Crop Protection

Full Text Available Botrytis cinerea is a necrotrophic fungus infecting over 230 plant species worldwide. This highly adaptable pathogen can afflict agricultural products from seed to storage, causing significant economic losses and instability in the food supply. Small protein virulence factors secreted by B. cinerea during infection play an important role in initiation and spread of disease. BcSnod1 was found to be abundantly expressed upon exposure to media containing strawberry extract. From sequence similarity, BcSnod2 was also identified and both were recognized as members of the Ceratoplatanin family of small phytotoxic proteins. Recombinant BcSnod1 was shown to have a phytotoxic effect and play an important role in pathogenicity while the role of BcSnod2 remains less clear. Both bacterial and yeast production systems are reported, though the bacterial protein is less toxic and mostly unfolded relative to that made in yeast. Compared to BcSnod1, recombinant bacterial BcSnod2 shows similar, but delayed phytotoxicity on tomato leaves. Further studies of these critical virulence factors and their inhibition promise to provide new avenues for crop protection.

A sporocyst residuum is present, composed of many granules of irregular size. The sporozoites are elongate, lying lengthwise in the sporocysts. Comparison with other species of the genus Eimeria parasitising members of family Testudinidae indicates that the presently described coccidium represents a new species. The name of Eimeria carinii Lainson, Costa & Shaw, 1990 is found to be preoccupied by a homonym, Eimeria carinii Pinto 1928 given to a coccidium from Rattus norvegicus. Therefore, it is replaced by Eimeria lainsoni nom. nov.

Objective: To construct magnetic nanoparticles targeting β-amyloid (Aβ) plaques, the pathological biomarker of Alzheimer's disease (AD) and to study their binding capability in vitro . Methods: Superparamagnetic nanoparticles Mn(0.6)Zn(0.4)Fe(2)O(4) (MZF) were coated with amphiphilic star-block copolymeric micelles and modified with Aβ-specific probe Pittsburgh compound B (PiB) to construct a novel magnetic nanoparticle MZF-PiB, which specifically targeted amyloid plaques. Transmission electron microscope was used to study the morphological features of MZF-PiB. Superparamagnetism of MZF-PiB was assessed by its r(2) relaxation rate by using 3.0 T MRI scanner. Cytotoxic test was applied to determine biosafety of MZF-PiB nanoparticles in differentiated human neuroblastoma cells (SH-SY5Y) and Madin-Darby canine kidney (MDCK). In vitro binding tests were conducted via immunohistochemistry on 6-month old AD mice brain sections. Differences of cell viability between groups were compared with one-way analysis of variance. Results: MZF-PiB nanoparticles were successfully constructed. Transmission electron microscope images showed that the nanoparticles were about 100 nm in size. The r(2) relaxation rate was 163.11 mMS(-1). No differences were found in cell viability of SH-SY5Y and MDCK incubated with MZF-PiB suspension for 24 h or 48 h when compared with those of untreated cells ( F =2.336, 2.539, 0.293, 1.493, all P >0.05). In vitro binding tests indicated that the MZF-PiB were specifically bound to amyloid plaques. The smallest size of detected plaques was 27 μm. Conclusion: PiB-modified nanoparticles targeting Aβ are biologically safe and highly superparamagnetic, possessing the capability to detect amyloid plaques early in vitro and the potential for early diagnosis of AD.

Billboard advertising: an avenue for communicating healthcare information and opportunities to disadvantaged populations.

Healthcare communications directed toward the disadvantaged have the potential to elevate the health status of these underprivileged and highly-challenged individuals. From conveying advice which encourages healthy lifestyles to communicating the location and availability of various medical resources, healthier lives and communities can be realized. Success on this front first requires establishing an effective communications link, something that is made more difficult as communications options available to the disadvantaged are more limited than those available to advantaged populations. One avenue which shows exceptional promise for successfully engaging the disadvantaged is that of billboard advertising. Willis-Knighton Health System's experiences and insights indicate that the characteristics and qualities of billboards, paired with the environmental circumstances typically faced by the less fortunate, create unique combinations which amplify consumption of billboard advertising content. Further, research suggests that the less privileged place greater reliance on the medium than do their more privileged counterparts, escalating the value and impact potential of billboard advertising directed toward the disadvantaged. Given the value afforded by health and wellness information successfully reaching the disadvantaged, opportunities to better distribute content to targeted audiences could very well improve community health. Billboard advertising appears to be well suited to engage the less fortunate, providing a productive pathway for the conveyance of helpful, supportive details, yielding healthier populations, enhanced opportunities, and better communities.

Substance abuse in Egypt is a serious public health threat. Recent studies have demonstrated increases in the prevalence of the use of tobacco, illegal drugs, and over-the-counter drugs, particularly among youth. We conducted focus groups with a total of 40 male and female youth participants, ages 12-14 and 15-18, recruited from two different areas (Cairo and Alexandria) in 2012. We investigated their knowledge and perceptions regarding current substance use, its sources, and promoting and protecting factors, broadly addressing the use of tobacco products, illicit and prescription drugs, inhaled substances such as glue and solvents, and alcohol. Our findings suggest that: (1) youth in Egypt had access to and were actively using substances encountered in similar research worldwide, including tobacco, alcohol, illicit drugs, glue sniffing, and pharmaceutical agents; (2) smoking cigarettes and using hashish were the most common practices, and Tramadol was the most commonly used pharmaceutical drug; (3) peer pressure from friends stood out as the most common reason to start and continue using substances, followed by adverse life events and having a parent or family member who used substances; (4) strict parenting, religiosity, and having non-user friends were among the factors perceived by youth to prevent substance use or help them quit using substances; (5) most youths were aware of the adverse health effects of substance use. These findings will inform the design of quantitative surveys aimed at estimating the prevalence of specific behaviors related to substance use among youth and potential avenues for prevention.

Preclinical, or asymptomatic, Alzheimer's disease (AD) refers to the presence of positive AD biomarkers in the absence of cognitive deficits. This research concept is being applied to define target populations for clinical drug development. In a prospective community-recruited cohort of cognitively intact older adults, we compared two amyloid imaging markers within subjects: 18 F-flutemetamol and 11 C-Pittsburgh compound B (PIB). In 32 community-recruited cognitively intact older adults aged between 65 and 80 years, we determined the concordance between binary classification based on 18 F-flutemetamol versus 11 C-PIB according to semiquantitative assessment (standardized uptake value ratio in composite cortical volume, SUVR comp ) and, alternatively, according to visual reads. We also determined the correlation between 18 F-flutemetamol and 11 C-PIB SUVR and evaluated how this was affected by the reference region chosen (cerebellar grey matter versus pons) and the use of partial volume correction (PVC) in this population. Binary classification based on semiquantitative assessment was concordant between 18 F-flutemetamol and 11 C-PIB in 94 % of cases. Concordance of blinded binary visual reads between tracers was 84 %. The Spearman correlation between 18 F-flutemetamol and 11 C-PIB SUVR comp with cerebellar grey matter as reference region was 0.84, with a slope of 0.98. Correlations in neocortical regions were significantly lower with the pons as reference region. PVC improved the correlation in striatum and medial temporal cortex. For the definition of preclinical AD based on 18 F-flutemetamol, concordance with 11 C-PIB was highest using semiquantitative assessment with cerebellar grey matter as reference region. (orig.)

A number of properties in the Albany/Colonie area have been identified as being potentially contaminated with uranium originating from the former National Lead Company's uranium forming plant in Colonie, New York. The Niagara-Mohawk property on Railroad Avenue in Colonie, New York, was the subject of a radiological investigation initiated June 11, 1987. This commercial property is an irregularly shaped lot partially occupied by an electric power substation and associated transmission lines. Portions of the property that were swampy and heavily vegetated were inaccessible to the survey team. There are no buildings on the property. A diagram showing the approximate boundaries and the 15-m grid network established for measurements on the property is shown. The lot included in the radiological survey was /approximately/45 m wide by 246 m deep. Two views of the property are shown. 13 refs., 6 figs., 4 tabs

A systematic review of satisfaction and pediatric obesity treatment: new avenues for addressing attrition.

2014-01-01

Pediatric obesity treatment programs report high attrition rates, but it is unknown if family experience and satisfaction contributes. This review surveys the literature regarding satisfaction in pediatric obesity and questions used in measurement. A systematic review of the literature was conducted using Medline, PsychINFO, and CINAHL. Studies of satisfaction in pediatric weight management were reviewed, and related studies of obesity were included. Satisfaction survey questions were obtained from the articles or from the authors. Eighteen studies were included; 14 quantitative and 4 qualitative. Only one study linked satisfaction to attrition, and none investigated the association of satisfaction and weight outcomes. Most investigations included satisfaction as a secondary aim or used single-item questions of overall satisfaction; only one assessed satisfaction in noncompleters. Overall, participants expressed high levels of satisfaction with obesity treatment or prevention programs. Surveys focused predominantly on overall satisfaction or specific components of the program. Few in-depth studies of satisfaction with pediatric obesity treatment have been conducted. Increased focus on family satisfaction with obesity treatment may provide an avenue to lower attrition rates and improve outcomes. Enhancing measurement of satisfaction to yield actionable responses could positively influence outcomes, and a framework, via patient-centered care principles, is provided. © 2013 National Association for Healthcare Quality.

Full Text Available All endeavors were devoted to investigate the views and feelings of stakeholders on the implementation of teachers’ professional development and its contribution to sustain academic programs quality at Adama University. A case study that constitutes qualitative and quantitative method was employed. In an attempt to achieve the objectives of the study, evidences were collected from students, staff members, professional development program coordinators, and management bodies. The data-collecting instruments for obtaining relevant information were questionnaires, interview, observation, and document analysis. The finding in relation to this study uncovers the fact that though continuous professional development has been perceived as the most useful avenue of teachers continuous and lifelong learning, for the most part, it is relegated to adhoc committees or interested group or institutional units in the system of university education/training. Moreover, the absence of PDP in the university organizational structure, clear mission and vision, defined and well-articulated policy, strategic plan, representatives in university senate meetings, adequate resources, well-identified and -preserved training facilities, and unit library were circumstances that in one way or another negatively affected the provision of effective professional development programs/trainings that may have adverse effect in the deliberation of quality education/training in Adama University.

Archeointensity study on baked clay samples taken from the reconstructed ancient kiln: implication for validity of the Tsunakawa-Shaw paleointensity method

Yamamoto, Yuhji; Torii, Masayuki; Natsuhara, Nobuyoshi

In 1972, a reconstruction experiment of a kiln had been done to reproduce an excavated kiln of the seventh century in Japan. Baked clay samples were taken from the floor surface and -20 cm level, and they have been stored after determinations of the paleomagnetic directions by partial alternating field demagnetizations. We recently applied the Tsunakawa-Shaw method to the samples to assess how reliable archeointensity results are obtained from the samples. A suite of the rock magnetic experiments and the scanning electron microscope observations elucidate that dominant magnetic carriers of the floor surface samples are Ti-poor titanomagnetite grains in approximately 10 nm size with single-domain and/or super-paramagnetic states, whereas contributions of multi-domain grains seem to be relatively large for the -20-cm level samples. From the floor surface samples, six out of the eight successful results were obtained and they give an average of 47.3 μT with a standard deviation of 2.2 μT. This is fairly consistent with the in situ geomagnetic field of 46.4 μT at the time of the reconstruction. They are obtained with a built-in anisotropy correction using anhysteretic remanent magnetization and without any cooling rate corrections. In contrast, only one out of four was successful from the -20-cm level samples. It yields an archeointensity of 31.6 μT, which is inconsistent with the in situ geomagnetic field. Considering from the in situ temperature record during the firing of the kiln and the unblocking temperature spectra of the samples, the floor surface samples acquired full thermoremanent magnetizations (TRMs) as their natural remanent magnetizations whereas the -20-cm level samples only acquired partial TRMs, and these differences probably cause the difference in the archeointensity results between the two sample groups. For archeointensity researches, baked clay samples from a kiln floor are considered to be ideal materials.

miRNAs in Tuberculosis: New Avenues for Diagnosis and Host-Directed Therapy

Directory of Open Access Journals (Sweden)

Naveed Sabir

2018-03-01

Full Text Available Tuberculosis (TB is one of the most fatal infectious diseases and a leading cause of mortality, with 95% of these deaths occurring in developing countries. The causative agent, Mycobacterium tuberculosis (Mtb, has a well-established ability to circumvent the host’s immune system for its intracellular survival. microRNAs (miRNAs are small, non-coding RNAs having an important function at the post-transcriptional level and are involved in shaping immunity by regulating the repertoire of genes expressed in immune cells. It has been established in recent studies that the innate immune response against TB is significantly regulated by miRNAs. Moreover, differential expression of miRNA in Mtb infection can reflect the disease progression and may help distinguish between active and latent TB infection (LTBI. These findings encouraged the application of miRNAs as potential biomarkers. Similarly, active participation of miRNAs in modulation of autophagy and apoptosis responses against Mtb opens an exciting avenue for the exploitation of miRNAs as host directed therapy (HDT against TB. Nanoparticles mediated delivery of miRNAs to treat various diseases has been reported and this technology has a great potential to be used in TB. In reality, this exploitation of miRNAs as biomarkers and in HDT is still in its infancy stage, and more studies using animal models mimicking human TB are advocated to assess the role of miRNAs as biomarkers and therapeutic targets. In this review, we attempt to summarize the recent advancements in the role of miRNAs in TB as immune modulator, miRNAs’ capability to distinguish between active and latent TB and, finally, usage of miRNAs as therapeutic targets against TB.

Challenging issues in the study of fiscally-induced migration.

Science.gov (United States)

Winer, S L

1986-01-01

This paper reviews Shaw's book, INTERMETROPOLITAN MIGRATION IN CANADA, which provides new evidence concerning the link between fiscal structure and internal migration. Shaw bases his work on a valuable new migration series he has put together from census data: intermetropolitan flows from 1956-1981. The existence of censua data at 5-year intervals permits Shaw enough data to estimate migration equations separately for the periods before and after 1971. A comparison of the role of fiscal variables before and after 1971 is interesting because unemployment insurance, equalization payments, and provincial natural resource revenues probably became more important in determining regional differences in incomes after 1971 than in the 20 years prior to that. Shaw suspects that migration behavior has become less sensitive to traditional market variables such as wage differentials and more sensitive to other factors, including quality of life indicators since 1950. The author thinks that Shaw's conclusion cannot rest comfortably on estimating equations that omit fiscal variables. The overall role of wage differentials in determining observed migration patterns is the product of the coefficient on wage variables and the actual evolution of wages over the estimation period. Another problem with the methodology used to contrast pre- and post-1971 migration equations is the apparent neglect of statistical testing for shifts in coefficients on the traditional economic variables and for shifts in the coefficients on the fiscal variables. The strongest of the useful results from the study concern the role of unemployment insurance. The evidence that these have an influence on internal migration is now compelling. Shaw's book adds substantial weight to the view that variation in fiscal structure plays a significant role in determining internal migration patterns.

The survey included a gamma radiation scan of the surface and at one meter above the surface, as well as radionuclide sampling of surface and subsurface soil. The survey objective was to determine whether this site was contaminated with radioactive residues derived from MCW, principally 232 Th. Results of the survey demonstrated radionuclide concentrations in excess of DOE remedial action criteria, primarily from the 232 Th decay chain, with some contamination from 226 Ra. The radionuclide distributions are typical of the type of material originating from the MCW site. 5 refs., 3 figs., 3 tabs

Previous studies have reported that the incidence of OSA is higher in patients with depression than in the general population. The purpose of this article was to investigate clinical risk factors to predict OSA in depression disorders.Methods: A total of 115 patients diagnosed with major depressive disorder (MDD and bipolar disorder (in a major depressive episode, who underwent overnight polysomnography, were studied retrospectively. They were divided into two groups: non-OSA and OSA. The patients who had apnea–hypopnea index (AHI <5 were defined as the non-OSA group, whereas the OSA group was defined as those with an AHI ≥5. Logistic regression was used to analyze the association among AHI and clinical factors, including sex, age, body mass index (BMI, Hamilton Depression Rating Scale (HAMD, Hamilton Anxiety Rating Scale, Pittsburgh Sleep Quality Index (PSQI, and diagnosis (MDD or bipolar disorder [in a major depressive episode].Results: In 115 patients, 51.3% had OSA. Logistic regression analysis showed significant associations between AHI and diagnosis (MDD or bipolar disorder [in a major depressive episode], BMI, HAMD, and PSQI (P<0.05.Conclusion: The findings of our study suggested that the rate of depression being comorbid with OSA is remarkably high and revealed that there is a high rate of undetected OSA among depressive disorder patients and untreated OSA among mood

Little is known about Alzheimer's disease molecular proteins, beta-amyloid and paired helical filament (PHF) tau, in progressive supranuclear palsy (PSP). Recent techniques have been developed to allow for investigations of these proteins in PSP. We determined the frequency of beta-amyloid deposition in PSP, and whether beta-amyloid deposition in PSP is associated with PHF-tau deposition pattern, or clinical features. Thirty probable PSP participants underwent MRI, [ 18 F]AV-1451 PET and Pittsburgh compound B (PiB) PET. Apolipoprotein (APOE) genotyping was also performed. A global PiB standard-uptake value ratio (SUVR) was calculated. AV-1451 SUVRs were calculated for a set of Alzheimer's disease (AD)-related regions and a set of PSP-related regions. Voxel-level analyses were conducted to assess for differences in AV-1451 uptake patterns and MRI atrophy between PiB(+) and PiB(-) cases compared to 60 normal PiB(-) controls. Statistical testing for correlations and associations between variables of interest were also performed. Twelve subjects (40%) showed beta-amyloid deposition. Higher PiB SUVR correlated with older age but not with AV-1451 SUVR in the AD- or PSP-related regions. Higher AV-1451 SUVR in AD-related regions was associated with higher AV-1451 SUVR in PSP-related regions. We found little evidence for beta-amyloid related differences in clinical metrics, proportion of APOE e4 carriers, pattern of AV-1451 uptake, or pattern of atrophy. Beta-amyloid deposition occurs in a relatively high proportion of PSP subjects. Unlike in Alzheimer's disease, however, there is little evidence that beta-amyloid, and PHF-tau, play a significant role in neurodegeneration in PSP. Copyright © 2017 Elsevier Ltd.

Superfund Record of Decision (EPA Region 9): Nineteenth Avenue Landfill, Phoenix, AZ. (First remedial action), September 1989. Final report

International Nuclear Information System (INIS)

1989-01-01

The 213-acre Nineteenth Avenue Landfill is in an industrial area of Maricopa County, Phoenix, Arizona. State permitted landfill operations were conducted from 1957 to 1979 during which time approximately nine million cubic yards of municipal refuse, solid and liquid industrial wastes, and some medical wastes and materials containing low levels of radioactivity were deposited in the landfill. The State ordered the landfill closed in 1979 due to the periodic inundation of the landfill by flood waters from the Salt River Channel. Subsequently, the city covered the site with fill, stockpiled soil for final capping, installed ground water monitoring wells, built berms around the landfill, and installed a methane gas collection system. The remedial action is designed to mitigate threats resulting from flooding of the landfill, which has occurred intermittently since 1965. The primary contaminants of concern in the soil/refuse include VOCs such as toluene and xylenes

Preclinical, or asymptomatic, Alzheimer's disease (AD) refers to the presence of positive AD biomarkers in the absence of cognitive deficits. This research concept is being applied to define target populations for clinical drug development. In a prospective community-recruited cohort of cognitively intact older adults, we compared two amyloid imaging markers within subjects: {sup 18}F-flutemetamol and {sup 11}C-Pittsburgh compound B (PIB). In 32 community-recruited cognitively intact older adults aged between 65 and 80 years, we determined the concordance between binary classification based on {sup 18}F-flutemetamol versus {sup 11}C-PIB according to semiquantitative assessment (standardized uptake value ratio in composite cortical volume, SUVR{sub comp}) and, alternatively, according to visual reads. We also determined the correlation between {sup 18}F-flutemetamol and {sup 11}C-PIB SUVR and evaluated how this was affected by the reference region chosen (cerebellar grey matter versus pons) and the use of partial volume correction (PVC) in this population. Binary classification based on semiquantitative assessment was concordant between {sup 18}F-flutemetamol and {sup 11}C-PIB in 94 % of cases. Concordance of blinded binary visual reads between tracers was 84 %. The Spearman correlation between {sup 18}F-flutemetamol and {sup 11}C-PIB SUVR{sub comp} with cerebellar grey matter as reference region was 0.84, with a slope of 0.98. Correlations in neocortical regions were significantly lower with the pons as reference region. PVC improved the correlation in striatum and medial temporal cortex. For the definition of preclinical AD based on {sup 18}F-flutemetamol, concordance with {sup 11}C-PIB was highest using semiquantitative assessment with cerebellar grey matter as reference region.

Investors are a heterogeneous group, they may be large or small, rich or poor, expert or lay man and not all investors need equal degree of protection (Mayya, 1996). An investor has three objectives while investing his money, namely safety of invested money, liquidity position of invested money and return on investment. The return on investment may further be divided into capital gain and the rate of return on investment as interest or dividend. Among all investment options available, securities are considered the most challenging as well as rewarding. Securities include shares, debentures, derivatives, units of mutual funds, Government securities etc. An investor may be an individual or corporate legal entity investing funds with a view to derive maximum economic advantage from investment such as rate of return, capital appreciation, marketability, tax advantage and convenience of investment.The Capital market facilitates mobilization of savings of individuals and pools them into reservoir of capital which can be used for the economic development of a country. An efficient capital market is essential for raising capital by the corporate sector of the economy and for the protection of the interest of investors in corporate securities. There arises a need to strike a balance between raising of capital for economic development on one side and protection of investors on the other. Unless the interests of investors are protected, raising of capital, by corporates is not possible. Like, the primary objective of a senior citizenís asset allocation is the generation of regular income.

This work analysed different 5 cm depth fragments soils, with distinct characteristic s, collected at 8 points of the Tiete river marginal avenue at the Sao Paulo metropolitan region. The technique used for the analysis was the instrumental neutron activation analysis (INAA). Together with samples, metal concentration were measured in three reference materials BEN (IWG-GIT), GS-N (IWG-GIT) and Soil-7 (IAEA) for quality control of the results. These metals were analysed: arsenic (As), barium (Ba), chromium (Cr), cobalt (Co), antimony (Sb) e zinc (Zn); the obtained concentrations were compared with intervention limit values stipulated by the Companhia de Tecnologia de Saneamento Ambiental (CETESB). Those values indicate the soil quality for different use

The property at 90 Avenue C, Lodi, New Jersey is one of the vicinity properties of the former Maywood Chemical Works, Maywood, New Jersey designated for remedial action by the US Department of Energy (DOE). In July 1991, Bechtel National, Inc. performed a partial remedial action on this property. At the request of DOE, a team from Oak Ridge National Laboratory conducted an independent radiological verification survey in July, 1991 at this site. The purpose of the verification survey was to ensure the effectiveness of remedial actions performed within FUSRAP and to confirm the site's compliance with DOE guidelines. The radiological survey included surface gamma scans indoors and outdoors, ground-level beta-gamma measurements, and systematic and biased soil and material sampling. Results of the verification survey demonstrated that all radiological measurements on the portions of the property that had been remediated were within DOE guidelines. However, there still remains a portion of the property to be remediated that is not covered by this verification survey

Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Th, derived from the MCW site. The survey typically includes direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, 110 E. Hunter Avenue, Maywood, New Jersey (MJ022), was conducted during 1987. Following the removal of a small chunk of material showing elevated gamma exposure rates, all radionuclide concentrations and measurements conformed to DOE remedial action criteria. The slightly elevated radionuclide concentrations found in other soil samples were the result of naturally enhances radioactivity characteristic of some environmental materials such as coal ash and were unrelated to operations at the MCW site. The survey data demonstrate that the property requires no further action on the part of DOE. 4 refs., 2 figs., 3 tabs

2015-01-01

Full Text Available Background: Telepathology is increasingly being employed to support diagnostic consultation services. Prior publications have addressed technology aspects for telepathology, whereas this paper will address the clinical telepathology experience of KingMed Diagnostics, the largest independent pathology medical laboratory in China. Beginning in 2012 the University of Pittsburgh Medical Center (UPMC and KingMed Diagnostics partnered to establish an international telepathology consultation service. Materials and Methods: This is a retrospective study that summarizes the telepathology experience and diagnostic consultation results between UPMC and KingMed over a period of 3 years from January 2012 to December 2014. Results: A total of 1561 cases were submitted for telepathology consultation including 144 cases in 2012, 614 cases in 2013, and 803 in 2014. Most of the cases (61.4% submitted were referred by pathologists, 36.9% by clinicians, and 1.7% by patients in China. Hematopathology received the most cases (23.7%, followed by bone/soft tissue (21.0% and gynecologic/breast (20.2% subspecialties. Average turnaround time (TAT per case was 5.4 days, which decreased from 6.8 days in 2012 to 5.0 days in 2014. Immunostains were required for most of the cases. For some difficult cases, more than one round of immunostains was needed, which extended the TAT. Among 855 cases (54.7% where a primary diagnosis or impression was provided by the referring local hospitals in China, the final diagnoses rendered by UPMC pathologists were identical in 25.6% of cases and significantly modified (treatment plan altered in 50.8% of cases. Conclusion: These results indicate that international telepathology consultation can significantly improve patient care by facilitating access to pathology expertise. The success of this international digital consultation service was dependent on strong commitment and support from leadership, information technology expertise, and

Eighty-nine (89) percent of the electricity supplied in the 35-county Pittsburgh region (comprising parts of the states of Pennsylvania, Ohio, West Virginia, and Maryland) is generated by coal-fired power plants making this an ideal region in which to study the effects of the fine airborne particulates designated as PM{sub 2.5} emitted by the combustion of coal. This report demonstrates that during the period from 1999-2006 (1) sufficient and extensive exposure data, in particular samples of speciated PM{sub 2.5} components from 1999 to 2003, and including gaseous co-pollutants and weather have been collected, (2) sufficient and extensive mortality, morbidity, and related health outcomes data are readily available, and (3) the relationship between health effects and fine particulates can most likely be satisfactorily characterized using a combination of sophisticated statistical methodologies including latent variable modeling (LVM) and generalized linear autoregressive moving average (GLARMA) time series analysis. This report provides detailed information on the available exposure data and the available health outcomes data for the construction of a comprehensive database suitable for analysis, illustrates the application of various statistical methods to characterize the relationship between health effects and exposure, and provides a road map for conducting the proposed study. In addition, a detailed work plan for conducting the study is provided and includes a list of tasks and an estimated budget. A substantial portion of the total study cost is attributed to the cost of analyzing a large number of archived PM{sub 2.5} filters. Analysis of a representative sample of the filters supports the reliability of this invaluable but as-yet untapped resource. These filters hold the key to having sufficient data on the components of PM{sub 2.5} but have a limited shelf life. If the archived filters are not analyzed promptly the important and costly information they

1987-08-01

This document reports the results of a radiological assessment and remedial action program conducted by Argonne National Laboratory personnel at a radioactively contaminated private residence in Lansdowne, Pennsylvania. The program was conducted on the residence at 186 Lansdowne Avenue. The survey conducted by the ANL personnel indicated that several dozen areas or spots of contamination were present on all floors and the basement of the three-story house. Contamination was found on furniture, carpeting, walls, floors, woodwork, and ceilings. Remedial action undertaken to remove the contamination ranged from scrubbing, to scraping, to shaving of wood, to removal and disposal of items and material that could not be adequately decontaminated. Outdoors, contaminated soil was removed from the backyard, and the driveway was dug up so the contaminated subsurface material could be removed. The remedial action generated quantities of radioactive waste, including four 55-gallon drums and one M-III bin (120 ft 3 ) containing floor tile, concrete, personal items, furniture, floor scrapings, vermiculite absorbed scrub water, and other items. In addition, there were 24 M-III bins containing approximately 112 tons of contaminated soil and rock from the two contaminated areas in the backyard and from the contaminated subsurface of the driveway. 2 refs., 39 figs., 12 tabs

Gravitactic bioconvective patterns created by Tetrahymena pyriformis in a Hele-Shaw apparatus were realized and compared with theoretical results. There were found to be two thresholds for bioconvection development: the first indicates the transition from the diffusion to the steady convection state; the second corresponds to the transition from the steady to the unsteady convection state. The results showed that the Hele-Shaw apparatus may be used as a physical analogy of poro...

Recently, we reported an information density theory and an analysis of three-parameter plus shorter scan than conventional method (3P+) for the amyloid-binding ligand [11C]Pittsburgh compound B (PIB) as an example of a non-highly reversible positron emission tomography (PET) ligand. This article describes an extension of 3P + analysis to noninvasive '3P++' analysis (3P + plus use of a reference tissue for input function). In 3P++ analysis for [11C]PIB, the cerebellum was used as a reference tissue (negligible specific binding). Fifteen healthy subjects (NC) and fifteen Alzheimer's disease (AD) patients participated. The k3 (index of receptor density) values were estimated with 40-min PET data and three-parameter reference tissue model and were compared with that in 40-min 3P + analysis as well as standard 90-min four-parameter (4P) analysis with arterial input function. Simulation studies were performed to explain k3 biases observed in 3P++ analysis. Good model fits of 40-min PET data were observed in both reference and target regions-of-interest (ROIs). High linear intra-subject (inter-15 ROI) correlations of k3 between 3P++ (Y-axis) and 3P + (X-axis) analyses were shown in one NC (r2 = 0.972 and slope = 0.845) and in one AD (r2 = 0.982, slope = 0.655), whereas inter-subject k3 correlations in a target region (left lateral temporal cortex) from 30 subjects (15 NC + 15 AD) were somewhat lower (r2 = 0.739 and slope = 0.461). Similar results were shown between 3P++ and 4P analyses: r2 = 0.953 for intra-subject k3 in NC, r2 = 0.907 for that in AD and r2 = 0.711 for inter-30 subject k3. Simulation studies showed that such lower inter-subject k3 correlations and significant negative k3 biases were not due to unstableness of 3P++ analysis but rather to inter-subject variation of both k2 (index of brain-to-blood transport) and k3 (not completely negligible) in the reference region. In [11C]PIB, the applicability of 3

Financial Development and Economic Growth: Experiences of Selected Developing Economies

The last two decades of the twentieth century witnessed a series of financial reforms in emerging economics of Asia, Africa and Latin America. The seminal works of R.I. McKinnon and E.S. Shaw, which attribute the slow growth of these economies to financial repression, inspired many of these reforms. The McKinnon-Shaw thesis demonstrates how government regulations cause low savings and investment, and ultimately engender financial repression. Financial liberalization, in this view, creates mar...

Landslide in claystone derived soil

Energy Technology Data Exchange (ETDEWEB)

Richardson, A M

1979-07-01

This article describes a landslide that occured in the Pittsburgh area in a soil deposit derived from the Pittsburgh Redbed Claystone when a cut was made at the toe. (The Pittsburgh Redbed Claystone is the parent of much of the soil material involved in the Pittsburgh area and occurs about mid way between the base of Pittsburgh Coal and the top of the Upper Freepost Coal). The topography before the slide was known and the geometry of the slide mass was established. Slope stability analysis indicated that the landslide could have been predicted using effective stress-shear-strength parameters of s of 12 to 13 and c is 0, where s is angle of shearing resistance and c is cohesion intercept in terms of effective stresses.

Viscous Fingering in Deformable Systems

Science.gov (United States)

Guan, Jian Hui; MacMinn, Chris

2017-11-01

Viscous fingering is a classical hydrodynamic instability that occurs when an invading fluid is injected into a porous medium or a Hele-Shaw cell that contains a more viscous defending fluid. Recent work has shown that viscous fingering in a Hele-Shaw cell is supressed when the flow cell is deformable. However, the mechanism of suppression relies on a net volumetric expansion of the flow area. Here, we study flow in a novel Hele-Shaw cell consisting of a rigid bottom plate and a flexible top plate that deforms in a way that is volume-conserving. In other words, fluid injection into the flow cell leads to a local expansion of the flow area (outward displacement of the flexible surface) that must be coupled to non-local contraction (inward displacement of the flexible surface). We explore the impact of this volumetric confinement on steady viscous flow and on viscous fingering. We would like to thank EPSRC for the funding for this work.

The design and construction of large diameter pre-filter packed recovery wells at the Ninth Avenue Superfund Site

International Nuclear Information System (INIS)

Lombardo, S.L.; Maley, T.J.; Bono, B.A.

1992-01-01

Large diameter groundwater/oil recovery wells were installed in an unconfined sand aquifer at the Ninth Avenue Superfund Site in Gary, Indiana. To assure adequate filter packs, prefilter packed groundwater/oil recovery wells were selected to minimize silting by using appropriate screen slot size and filter pack. A properly sized filter pack was necessary to prevent the formation material from entering the well. During field drilling operations, open-quotes having sandsclose quotes and silting of existing wells were encountered. By using sieve analyses of the native aquifer soil, described by Driscoll (1989), the filter pack and screen slot size were selected. Prefilter packed well screens were selected for this site to assure the presence of a uniform filter pack, thus minimizing siltation in the wells. A prefilter packed well screen consists of a double screen with the interstitial space filled with granular filter pack material designed specifically for site conditions. These wells provide the adequate filter pack without the need to add additional filter pack material outside the well screen. Wells were installed using 12 1/4 inch ID hollow stem augers. This methodology is EPA-approved, expeditious, and inexpensive. Level B personal protective equipment was required during installation. Therefore, the advantages of hollow stem drilling include short drilling time and no circulation fluids. The 14 recovery wells were successfully installed in 14 days using the hollow stem auger drilling technique. Observations during well development revealed little or no silt present in purged groundwater

Geothermal resource assessment of western San Luis Valley, Colorado

Energy Technology Data Exchange (ETDEWEB)

Zacharakis, Ted G.; Pearl, Richard Howard; Ringrose, Charles D.

1983-01-01

The Colorado Geological Survey initiated and carried out a fully integrated assessment program of the geothermal resource potential of the western San Luis Valley during 1979 and 1980. The San Luis Valley is a large intermontane basin located in southcentral Colorado. While thermal springs and wells are found throughout the Valley, the only thermal waters found along the western part of the Valley are found at Shaw Warm Springs which is a relatively unused spring located approximately 6 miles (9.66 km) north of Del Norte, Colorado. The waters at Shaws Warm Spring have a temperature of 86 F (30 C), a discharge of 40 gallons per minute and contain approximately 408 mg/l of total dissolved solids. The assessment program carried out din the western San Luis Valley consisted of: soil mercury geochemical surveys; geothermal gradient drilling; and dipole-dipole electrical resistivity traverses, Schlumberger soundings, Audio-magnetotelluric surveys, telluric surveys, and time-domain electro-magnetic soundings and seismic surveys. Shaw Warm Springs appears to be the only source of thermal waters along the western side of the Valley. From the various investigations conducted the springs appear to be fault controlled and is very limited in extent. Based on best evidence presently available estimates are presented on the size and extent of Shaw Warm Springs thermal system. It is estimated that this could have an areal extent of 0.63 sq. miles (1.62 sq. km) and contain 0.0148 Q's of heat energy.

Background Conventional management for concussion involves prescribed rest and progressive return to activity. Recent evidence challenges this notion and suggests that active approaches may be effective for some patients. Previous concussion consensus statements provide limited guidance regarding active treatment. Objective To describe the current landscape of treatment for concussion and provide summary agreements related to treatment in order to assist clinicians in the treatment of concussion. Methods On October 14–16, 2015, the Targeted Evaluation & Active Management (TEAM) Approaches To Treating Concussion meeting was convened in Pittsburgh, Pennsylvania, USA. 37 concussion experts from neuropsychology, neurology, neurosurgery, sports medicine, physical medicine and rehabilitation, physical therapy, athletic training, and research, and 12 individuals representing sport, military, and public health organizations attended the meeting. The 37 experts indicated their agreement on a series of statements using an audience response system clicker device. Results A total of 16 statements of agreement were supported covering: 1) Summary of the Current Approach to Treating Concussion, 2) Heterogeneity and Evolving Clinical Profiles of Concussion, 3) Targeted Evaluation and Active Management Approach to Concussion Treatment: Specific Strategies, and 4) Future Directions: A Call to Research. Support (ie, response of agree or somewhat agree) for the statements ranged from to 97–100%. Conclusion Concussions are characterized by diverse symptoms and impairments and evolving clinical profiles; recovery varies based on modifying factors, injury severity, and treatments. Active and targeted treatments may enhance recovery following concussion. Research is needed on concussion clinical profiles, biomarkers, and the effectiveness and timing of treatments.

Water-quality trading requires inducing permit prices that account properly for spatially explicit damage relationships. We compare recent work by Hung and Shaw (2005) and Farrow et al. (2005) for river systems exhibiting branching and nonlinear damages. The Hung-Shaw scheme is robust to nonlinear damages, but not to hot spots occurring at the confluence of two branches. The Farrow et al. (2005) scheme is robust to branching, but not to nonlinear damages. We also compare the two schemes to each other. Neither dominates from a welfare perspective, but the comparison appears to tilt in favor of the Farrow et al. scheme.

Using theories of affect and queer temporality, this article examines Split Britches' Lost Lounge as lesbian resistance to the pressures to remember or forget the past, condemn or embrace the future. In this piece, butch-femme duo Peggy Shaw and Lois Weaver develop a retro performativity that pushes back against systems that strive to make lesbianism invisible, private, and apolitical. Through performances that resignify past pop culture artifacts, particularly the duo of Louis Prima and Keely Smith, Shaw and Weaver perform a past that is simultaneously lost and embodied, pressuring the audience to reconsider notions of progress and beauty.

DOE awarded funds to support a demonstration project to illustrate how access to solar power and green roof systems could improve building performance and long-term outcomes for the building owner and multiple nonprofit tenants housed in the building. Since being placed in service the solar PV system has saved approximately $1,000 per month in energy costs. The green roof has added to this benefit by naturally cooling the building and has helped reduce local road flooding by retaining storm water. These elements have improved the quality of life in the low-income community in which the building is located by allowing social service organizations to focus more of their resources on programs and job creation.

O modelo de liberalização financeira dos anos 1990: 'restatement' ou auto-crítica? The financial liberalization model in the 1990s: a restatement or self-criticism?

Directory of Open Access Journals (Sweden)

Jennifer Hermann

2003-01-01

Full Text Available The paper examines the revisions suffered by the financial liberalization model during the decades of 1980 and1990. Such revisions were forced by two sets of factors: the unfavorable results of some econometric tests of the Shaw-McKinnon model and the experiences of several developed (DC and developing (LDC countries with the liberalization policy. In the econometric field, the tests have shown to play a weak explaining role of the two key variables of the model: the real interest rate and the saving rate. As for DC and LDC experiences, the main challenge to the original Shaw-McKinnon model was the banking and currency crises that have followed the liberalization policy in most of the cases. Facing these constraints, the 'modern version' of liberalization has embodied several (Keynesian critiques to Shaw-McKinnon's financial theory and policy and has been forced to allow for the need of some degree of government intervention in the free choice of financial market concerning its portfolio composition. Further, the new model make a real self-critique, by admitting that, under certain conditions, some degree of financial repression could be necessary and is even beneficial to financial development.

McGee, Andrew

2011-01-01

In this paper, I discuss David Shaw's claim that the body of a terminally ill person can be conceived as a kind of life support, akin to an artificial ventilator. I claim that this position rests upon an untenable dualism between the mind and the body. Given that dualism continues to be attractive to some thinkers, I attempt to diagnose the reasons why it continues to be attractive, as well as to demonstrate its incoherence, drawing on some recent work in the philosophy of psychology. I conclude that, if my criticisms are sound, Shaw's attempt to deny the distinction between withdrawal and euthanasia fails. © 2011 American Society of Law, Medicine & Ethics, Inc.

HGF, also known as scatter factor (SF, is the only known ligand for MET. MET is a master regulator of cell growth and division (mitogenesis, mobility (motogenesis, and differentiation (morphogenesis; it plays an important role in normal development and tissue regeneration. The HGF-MET axis is frequently dysregulated in cancer by MET gene amplification, translocation, and mutation, or by MET or HGF protein overexpression. MET dysregulation is associated with an increased propensity for metastatic disease and poor overall prognosis across multiple tumor types. Targeting the dysregulated HGF-MET pathway is an area of active research; a number of monoclonal antibodies to HGF and MET, as well as small molecule inhibitors of MET, are under development. This review summarizes the key biological features of the HGF-MET axis, its dysregulation in cancer, and the therapeutic agents targeting the HGF-MET axis, which are in development.Keywords: MET inhibitor, HGF inhibitor, cancer

Denver Radium Site -- Operable Unit I closeout report for the US Environmental Protection Agency

International Nuclear Information System (INIS)

1992-08-01

The Denver Radium Site consists of properties in the Denver, Colorado, area having radioactive contamination left from radium processing in the early 1900s. The properties are divided into 11 gaps or operable units to facilitate remedial action of the Site. Operable Unit I is an 8-acre block bounded by Quivas Street to the east, Shoshone Street to the west, West 12th Avenue to the south, and West 13th Avenue to the north. The primary focus of interest concerning investigations of radiological contamination was a radium, vanadium, and uranium processing facility at 1201 Quivas Street owned by the Pittsburgh Radium Company (PRC) from 1925 until 1926. The Radium Ores Company, which was associated with PRC, operated the facility until 1927. A Remedial investigation (RI) of Operable Unit I was prepared by Jacobs Engineering Group and CH 2 M Hill on behalf of EPA in April 1986. The draft Feasibility Study (FS), prepared by Jacobs Engineering Group and CH 2 M Hill, was issued in July 1987 (the final FS is the Community Relations Responsiveness Summary with an errata to the draft, issued September 1987). The RI focused on radium uranium processing residues discarded in the early 1900s. These residues contained uranium, radium, and thorium. EPA s Community Relations Plan involved the community in the decision-making process relating to the remedy to be implemented at Operable Unit X, and promoted communications among interested parties throughout the course of the project. The remedial action alternative preferred by EPA for Operable Unit I was Off-Site Permanent Disposal. Because a permanent disposal facility was not available at the time the Record of Decision was issued in September 1987, EPA selected the On-Site Temporary Containment (capping) with the Off-Site Permanent Disposal alternative

Bursting of a bubble confined in between two plates

2015-11-01

Rupture of liquid thin films, driven by surface tension, has attracted interests of scientists for many years. It is also a daily phenomenon familiar to everyone in the form of the bursting of soap films. In recent years, many studies in confined geometries (e.g. in a Hele-Shaw cell) have revealed physical mechanisms of the dynamics of bubbles and drops. As for a liquid film sandwiched in between another liquid immiscible to the film liquid in the Hele-Shaw cell, it is reported that the thin film bursts at a constant speed and the speed depends on the viscosity of the surrounding liquid when the film is less viscous, although a rim is not formed at the bursting tip; this is because the circular symmetry of the hole in the bursting film is lost. Here, we study the bursting speed of a thin film sandwiched between air instead of the surrounding liquid in the Hele-Shaw cell to seek different scaling regimes. By measuring the bursting velocity and the film thickness of an air bubble with a high speed camera, we have found a new scaling law in viscous regime. This research was partly supported by ImPACT Program of Council for Science, Technology and Innovation (Cabinet Office, Government of Japan).

Full Text Available Background. Chronic poor oral health has a high prevalence in Appalachia, a large region in the eastern USA. The Center for Oral Health Research in Appalachia (COHRA has been enrolling pregnant women and their babies since 2011 in the COHRA2 study of genetic, microbial, and environmental factors involved in oral health in Northern Appalachia. Methods. The COHRA2 protocol is presented in detail, including inclusion criteria (healthy, adult, pregnant, US Caucasian, English speaking, and nonimmunocompromised women, recruiting (two sites: Pittsburgh, Pennsylvania, and West Virginia, USA, assessments (demographic, medical, dental, psychosocial/behavioral, and oral microbial samples and DNA, timelines (longitudinal from pregnancy to young childhood, quality control, and retention rates. Results. Preliminary oral health and demographic data are presented in 727 pregnant women, half from the greater Pittsburgh region and half from West Virginia. Despite similar tooth brushing and flossing habits, COHRA2 women in West Virginia have significantly worse oral health than the Pittsburgh sample. Women from Pittsburgh are older and more educated and have less unemployment than the West Virginia sample. Conclusions. We observed different prevalence of oral health and demographic variables between pregnant women from West Virginia (primarily rural and Pittsburgh (primarily urban. These observations suggest site-specific differences within Northern Appalachia that warrant future studies.

Are the Insomnia Severity Index and Pittsburgh Sleep Quality Index valid outcome measures for Cognitive Behavioral Therapy for Insomnia? Inquiry from the perspective of response shifts and longitudinal measurement invariance in their Chinese versions.

Science.gov (United States)

Chen, Po-Yi; Jan, Ya-Wen; Yang, Chien-Ming

2017-07-01

The purpose of this study was to examine whether the Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) are valid outcome measures for Cognitive Behavioral Therapy for Insomnia (CBT-I). Specifically, we tested whether the factorial parameters of the ISI and the PSQI could remain invariant against CBT-I, which is a prerequisite to using their change scores as an unbiased measure of the treatment outcome of CBT-I. A clinical data set including scores on the Chinese versions of the ISI and the PSQI obtained from 114 insomnia patients prior to and after a 6-week CBT-I program in Taiwan was analyzed. A series of measurement invariance (MI) tests were conducted to compare the factorial parameters of the ISI and the PSQI before and after the CBT-I treatment program. Most factorial parameters of the ISI remained invariant after CBT-I. However, the factorial model of the PSQI changed after CBT-I treatment. An extra loading with three residual correlations was added into the factorial model after treatment. The partial strong invariance of the ISI supports that it is a valid outcome measure for CBT-I. In contrast, various changes in the factor model of the PSQI indicate that it may not be an appropriate outcome measure for CBT-I. Some possible causes for the changes of the constructs of the PSQI following CBT-I are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

The double Laplacian growth

International Nuclear Information System (INIS)

Loutsenko, I.; Yermolayeva, O.

2008-06-01

The dynamics of the idealized Laplacian growth (or the Hele-Shaw problem) can be approximated by the Poiselle flow which in appropriate units takes the form of the Darcy law. In this paper we account for the liquid inertia in the Hele-Shaw problem at zero surface tension limit. The Laplace dynamics for the pressure is extended here with one more for the velocity potential for which we call this growth process the Double Laplacian. The application of the conformal mappings technique leads to doubled dynamics for both the conformal map and the complex potential, which is presented in the paper for the radial and the planar growth. We apply the stability analysis and discuss the integrability for the stated problem. (author)

The experience of the Shaw Group Ltd. in becoming an active supplier and participant in the Sable Offshore Energy Project was described. The Nova Scotia company began in 1861 as a small manufacturer of clay brick and tile. In order to ensure the company's long-term growth, the company began to diversify in the 1960s into fields such as concrete pipe and industrial aggregate production, transportation and community development. In 1975, they began looking into the potential of getting into the pipe coating business for the offshore petroleum industry. The process began with a search for a partner. Today, the company is responsible for the the epoxy and heavy-weight coating on subsea gathering lines and the main line from Sable Island to the mainland. In addition, the Shaw group of companies provide the full spectrum of management expertise, including purchasing, financial control, health and safety planning, labour procurement and the promotion of Nova Scotian and Canadian content throughout the project. The success of the Shaw Group in penetrating the oil and gas industry developments in eastern Canada should be an object lesson to all local companies that although initially some opportunities may appear to be beyond the scope and capabilities of local companies, imagination and willingness to take the risk to convert a problem into an opportunity can render even relatively small enterprises able to participate in major developments

Evaluating perceptual integration: uniting response-time- and accuracy-based methodologies.

Eidels, Ami; Townsend, James T; Hughes, Howard C; Perry, Lacey A

2015-02-01

This investigation brings together a response-time system identification methodology (e.g., Townsend & Wenger Psychonomic Bulletin & Review 11, 391-418, 2004a) and an accuracy methodology, intended to assess models of integration across stimulus dimensions (features, modalities, etc.) that were proposed by Shaw and colleagues (e.g., Mulligan & Shaw Perception & Psychophysics 28, 471-478, 1980). The goal was to theoretically examine these separate strategies and to apply them conjointly to the same set of participants. The empirical phases were carried out within an extension of an established experimental design called the double factorial paradigm (e.g., Townsend & Nozawa Journal of Mathematical Psychology 39, 321-359, 1995). That paradigm, based on response times, permits assessments of architecture (parallel vs. serial processing), stopping rule (exhaustive vs. minimum time), and workload capacity, all within the same blocks of trials. The paradigm introduced by Shaw and colleagues uses a statistic formally analogous to that of the double factorial paradigm, but based on accuracy rather than response times. We demonstrate that the accuracy measure cannot discriminate between parallel and serial processing. Nonetheless, the class of models supported by the accuracy data possesses a suitable interpretation within the same set of models supported by the response-time data. The supported model, consistent across individuals, is parallel and has limited capacity, with the participants employing the appropriate stopping rule for the experimental setting.

Nonlinear normal vibration modes in the dynamics of nonlinear elastic systems

International Nuclear Information System (INIS)

Mikhlin, Yu V; Perepelkin, N V; Klimenko, A A; Harutyunyan, E

2012-01-01

Nonlinear normal modes (NNMs) are a generalization of the linear normal vibrations. By the Kauderer-Rosenberg concept in the regime of the NNM all position coordinates are single-values functions of some selected position coordinate. By the Shaw-Pierre concept, the NNM is such a regime when all generalized coordinates and velocities are univalent functions of a couple of dominant (active) phase variables. The NNMs approach is used in some applied problems. In particular, the Kauderer-Rosenberg NNMs are analyzed in the dynamics of some pendulum systems. The NNMs of forced vibrations are investigated in a rotor system with an isotropic-elastic shaft. A combination of the Shaw-Pierre NNMs and the Rauscher method is used to construct the forced NNMs and the frequency responses in the rotor dynamics.

Flow in porous media under the influence of thermal fields

Energy Technology Data Exchange (ETDEWEB)

Bories, S; Thirriot, C

1970-01-01

Fluid flow in porous media, including natural convection caused by temperature fields, is of particular importance in the exploitation of petroleum deposits. Laboratory experiments with a horizontal Hele-Shaw model in which the convection currents can be visually observed, are reported. The main observations are concerned with fairly stable flow regime cells and the velocity distribution. Photos of the flow, and graphs of the temperature distribution measured by interferometric methods, are given. The essential elements observed are well-represented by a simplified theory; at large Reynolds numbers, large temperature gradients have been observed in the vicinity of the isothermal boundaries. The temperature distribution can be expressed by a dimensionless law, and it seems possible to generalize the observations from the Hele-Shaw model to flow in porous media.

Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Th, derived from the MCW site. The survey typically includes direct measurement of the gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, the Firemen's Memorial Park and Fire Hall number sign 2, Garibaldi Avenue and Kennedy Drive, Lodi, New Jersey (LJ066) was conducted during 1987. Results of the survey demonstrated radionuclide concentrations in excess of the DOE Formerly Utilized Sites Remedial Action Program criteria. The radionuclide distributions are typical of the type of material originating from the MCW site. 4 refs., 10 figs., 3 tabs

On the metamorphic history of an Archaean granitoid greenstone terrane, East Pilbara, Western Australia, using the /sup 40/Ar//sup 39/Ar age spectrum technique

Wijbrans, J.R.; McDougall, I.

1987-07-01

Age spectrum analyses of blue-green hornblendes from amphibolites from the Western Shaw Belt, East Pilbara, Western Australia, indicate an age of at least 3200 Ma for early regional metamorphism. Ages on hornblende and muscovite from the narrow contact zone with the adjacent Yule Batholith probably data updoming of the granitoid gneiss terranes at 2950 Ma. Hornblendes from within the Shaw Batholith and from a contact zone of a post-tectonic granitoid yield ages of 2840-2900 Ma, indicating either prolonged high temperatures within the granitoid gneiss terranes or a separate thermal pulse associated with the intrusion of post-tectonic granitoids. The preservation of very old hornblendes in a narrow greenstone belt surrounded by massive granitoid gneiss domes indicates that remarkable contrasts in metamorphic geotherms existed over short distances during the Late Archaean, suggesting that updoming occurred during a period of rapid tectonism.

Seven areas of research are discussed. A method was developed for analyzing samples for their major constituent elements by irradiating with protons and detecting prompt gamma rays, mostly produced in (p,p'γ) reactions. Among other applications, the method was used to analyze air particulates for C, N, O, Al, Si, S, Co, and Fe. Trace element analysis by proton or alpha particle induced x-ray fluorescence was used on thin samples in a study of the variations of Pb, Br, Fe, and Zn in air particulates as a function of time. Among other applications this method was also used in studying trace elements in rainwater. An x-ray fluorescence method that is effective in the analysis of thick samples was developed. A method based on measuring energies of elastically scattered protons was developed for the analysis of light elements. The use of proton and neutron activation analyses, as well as methods for studying depth profiles for hydrogen and helium in materials are discussed

Thalyta Cristina Mansano-Schlosser

Full Text Available ABSTRACT Objectives: to analyze the factors associated with poor sleep quality, its characteristics and components in women with breast cancer prior to surgery for removing the tumor and throughout the follow-up. Method: longitudinal study in a teaching hospital, with a sample of 102 women. The following were used: a questionnaire for sociodemographic and clinical characterization, the Pittsburgh Sleep Quality Index; the Beck Depression Inventory; and the Herth Hope Scale. Data collection covered from prior to the surgery for removal of the tumor (T0 to T1, on average 3.2 months; T2, on average 6.1 months; and T3, on average 12.4 months. Descriptive statistics and the Generalized Estimating Equations model were used. Results: depression and pain contributed to the increase in the score of the Pittsburgh Sleep Quality Index, and hope, to the reduction of the score - independently - throughout follow-up. Sleep disturbances were the component with the highest score throughout follow-up. Conclusion: the presence of depression and pain, prior to the surgery, contributed to the increase in the global score of the Pittsburgh Sleep Quality Index, which indicates worse quality of sleep throughout follow-up; greater hope, in its turn, influenced the reduction of the score of the Pittsburgh Sleep Quality Index.

On the metamorphic history of an Archaean granitoid greenstone terrane, East Pilbara, Western Australia, using the 40Ar/39Ar age spectrum technique

International Nuclear Information System (INIS)

Wijbrans, J.R.; McDougall, I.

1987-01-01

Age spectrum analyses of blue-green hornblendes from amphibolites from the Western Shaw Belt, East Pilbara, Western Australia, indicate an age of at least 3200 Ma for early regional metamorphism. Ages on hornblende and muscovite from the narrow contact zone with the adjacent Yule Batholith probably data updoming of the granitoid gneiss terranes at 2950 Ma. Hornblendes from within the Shaw Batholith and from a contact zone of a post-tectonic granitoid yield ages of 2840-2900 Ma, indicating either prolonged high temperatures within the granitoid gneiss terranes or a separate thermal pulse associated with the intrusion of post-tectonic granitoids. The preservation of very old hornblendes in a narrow greenstone belt surrounded by massive granitoid gneiss domes indicates that remarkable contrasts in metamorphic geotherms existed over short distances during the Late Archaean, suggesting that updoming occurred during a period of rapid tectonism.

The new species is diagnosed and compared to other species in the genus. It was reared from larvae of Pteronymia zerlina (Hewitson, 1855) (Lepidoptera: Nymphalidae, Ithomiinae) found feeding on leaves of Solanum (Solanaceae). The parasitoid is solitary. This is the first record of a Meteorus species attacking ithomiine Nymphalidae.

Modeling and Simulation of Fiber Orientation in Injection Molding of Polymer Composites

Directory of Open Access Journals (Sweden)

Jang Min Park

2011-01-01

Full Text Available We review the fundamental modeling and numerical simulation for a prediction of fiber orientation during injection molding process of polymer composite. In general, the simulation of fiber orientation involves coupled analysis of flow, temperature, moving free surface, and fiber kinematics. For the governing equation of the flow, Hele-Shaw flow model along with the generalized Newtonian constitutive model has been widely used. The kinematics of a group of fibers is described in terms of the second-order fiber orientation tensor. Folgar-Tucker model and recent fiber kinematics models such as a slow orientation model are discussed. Also various closure approximations are reviewed. Therefore, the coupled numerical methods are needed due to the above complex problems. We review several well-established methods such as a finite-element/finite-different hybrid scheme for Hele-Shaw flow model and a finite element method for a general three-dimensional flow model.

Compensating Injury to Autonomy in English Negligence Law: Inconsistent Recognition.

Science.gov (United States)

Keren-Paz, Tsachi

2018-04-10

Recently in Shaw v Kovac, the Court of Appeal seemed to have rejected a standalone injury to autonomy (ITA) as actionable in negligence, in an informed consent case. In this article, I argue that Shaw can be explained away, and that English law recognizes ITA as actionable in a series of cases, some of which-Bhamra, Tracey, and Yearworth-were not hitherto understood to do so. However, the under-theorization in the cases leads to inconsistencies. Like cases (Rees/Yearworth; Chester/Tracey) are not treated alike; ITA is misunderstood to be about 'religious offence' (Bhamra) and property loss (Yearworth) and worse still, the more serious type 2 ITA (Rees) gives rise to a weaker remedy (of exceptional nature aside) than the less serious type 1 injury (Chester). A better understanding of the different manifestations of ITA will lead to results which are both more consistent and more justified on the merit.

This article describes the Carolina-Shaw Partnership for the Elimination of Health Disparities efforts to engage a diverse group of Black churches in a sustainable network. We sought to develop a diverse network of 25 churches to work with the Carolina-Shaw Partnership to develop sustainable health disparities research, education, and intervention initiatives. Churches were selected based on location, pastoral buy-in, and capacity to engage. A purposive sampling technique was applied. (1) Collecting information on the location and characteristics of churches helps to identify and recruit churches that possess the desired qualities and characteristics. (2) The process used to identify, recruit, and select churches is time intensive. (3) The time, energy, and effort required managing an inter-institutional partnership and engage churches in health disparities research and interventions lends itself to sustainability. The development of a sustainable network of churches could lead to successful health disparities initiatives.

New Avenues for Nanoparticle-Related Therapies

Science.gov (United States)

Zhao, Michael; Liu, Mingyao

2018-05-01

Development of nanoparticle-based drug delivery systems has been attempted for the treatment of cancer over the past decade. The enhanced permeability and retention (EPR) effect is the major mechanism to passively deliver nanodrugs to tumor tissue. However, a recent systematic review demonstrated limited success of these studies, with the clearance of nanoparticles by the mononuclear phagocytic system (MPS) being a major hurdle. Herein, we propose that nanotechnologists should reconsider their research focuses, aiming for therapeutic targets other than cancer. Treatments for diseases that do not (or less) rely on EPR should be considered, such as active targeting or MPS evasion systems. For example, systemic delivery of drugs through intravenous injection can be used to treat sepsis, multi-organ failure, metabolic disorders, blood diseases, immune and autoimmune diseases, etc. Local delivery of nanodrugs to organs such as the lung, rectum, or bladder may enhance the local drug concentration with less clearance via MPS. In transplant settings, ex vivo organ perfusion provides a new route to repair injury of isolated organs in the absence of MPS. Based on a similar concept, chemotherapy with in vivo lung perfusion techniques and other isolated organ perfusion provides opportunities for cancer therapy.

Pharmaceutical technology management--profitable business avenue.

Science.gov (United States)

Puthli, Shivanand P

2010-01-01

Growing research expenditure, regulatory framework and generic erosion have forced pharmaceutical companies globally to resort to pharmaceutical technology management (PTM). Indeed, the pharmaceutical industry has witnessed the impact of innovative drug delivery and device technologies and their influence on business. PTM has given a new business insight with greater profits and enhancement of product franchise. Promising breakthrough technologies have not been able to reach a commercial platform largely owing to lack of capital at the preliminary stages of the product development program. Intellectual property plays a considerable role in protecting innovative technologies. Joint ventures and strategic alliances also become important for commercializing a new technology. The synergy of PTM with options of in-licensing is expected to infuse newer opportunities to the pharmaceutical business.

Ferrofluid spiral formations and continuous-to-discrete phase transitions under simultaneously applied DC axial and AC in-plane rotating magnetic fields

International Nuclear Information System (INIS)

Rhodes, Scott; Perez, Juan; Elborai, Shihab; Lee, Se-Hee; Zahn, Markus

2005-01-01

New flows and instabilities are presented for a ferrofluid drop contained in glass Hele-Shaw cells with simultaneously applied in-plane clockwise rotating and DC axial uniform magnetic fields. When a ferrofluid drop is stressed by a uniform DC axial magnetic field, up to ∼250 G in 0.9-1.4 mm gap Hele-Shaw cells, the drop forms a labyrinth pattern. With subsequent application of an in-plane uniform rotating magnetic field, up to ∼100 G rms at frequency 20-40 Hz, smooth spirals form from viscous shear due to ferrofluid flow. If the rotating magnetic field is applied first, the drop is held together without a labyrinth. Gradual increase of the DC axial magnetic field, to a critical magnetic field value, results in an abrupt phase transformation from a large drop to many small discrete droplets. A preliminary minimum magnetization and surface energy analysis is presented to model the phase transformation

Heat dispersion in rivers

International Nuclear Information System (INIS)

Shaw, T.L.

1974-01-01

One of the tasks of the Sonderforschungsbereich 80 is to study the dispersion of heat discharged into rivers and other bodies of water and to develop methods which permit prediction of detrimental effects caused by the heated discharges. In order to help the SFB 80 to specify this task, Dr. Shaw, lecturer of Civil Engineering at the Bristol University, conducted a literature survey on heat-dispersion studies during the two months which he spent as a visiting research fellow with the SFB 80 at the University of Karlsruhe in the summer of 1973. The following report is the outcome of this survey. It gives Dr. Shaw's assessment of the present state of knowledge - based almost exclusively on literature in the English language - and compares this with the knowledge required by river planners. The apparent discrepancy leads to suggestions for future research. Selected references as well as a representative bibliography can be found at the end of the report. (orig.) [de

Full Text Available Anuj Patel, Weijing Sun Division of Hematology-Oncology, University of Pittsburgh Cancer Institute, University of Pittsburgh School of Medicine, Pittsburgh, PA, USA Abstract: The combination of cytotoxic chemotherapy and antiangiogenic agents has become a conventional treatment option for patients with metastatic colorectal cancer. Ziv-aflibercept is a fusion protein which acts as a decoy receptor for vascular endothelial growth factor (VEGF-A, VEGF-B, and placental growth factor (PlGF; it was approved in combination with 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI for the treatment of patients with metastatic colorectal cancer that is resistant to or has progressed after an oxaliplatin-containing fluoropyrimidine-based regimen. Herein we review the role of tumor angiogenesis as the rationale for antiangiogenic therapy, the clinical data associated with ziv-aflibercept, and its current role as a treatment option compared to other antiangiogenic agents, such as bevacizumab and regorafenib.

Objective Oronasal fistula is an important complication of cleft palate repair that is frequently used to evaluate surgical quality, yet reliability of fistula classification has never been examined. The objective of this study was to determine the reliability of oronasal fistula classification both within individual surgeons and between multiple surgeons. Design Using intraoral photographs of children with repaired cleft palate, surgeons rated the location of palatal fistulae using the Pittsburgh Fistula Classification System. Intrarater and interrater reliability scores were calculated for each region of the palate. Participants Eight cleft surgeons rated photographs obtained from 29 children. Results Within individual surgeons reliability for each region of the Pittsburgh classification ranged from moderate to almost perfect (κ = .60-.96). By contrast, reliability between surgeons was lower, ranging from fair to substantial (κ = .23-.70). Between-surgeon reliability was lowest for the junction of the soft and hard palates (κ = .23). Within-surgeon and between-surgeon reliability were almost perfect for the more general classification of fistula in the secondary palate (κ = .95 and κ = .83, respectively). Conclusions This is the first reliability study of fistula classification. We show that the Pittsburgh Fistula Classification System is reliable when used by an individual surgeon, but less reliable when used among multiple surgeons. Comparisons of fistula occurrence among surgeons may be subject to less bias if they use the more general classification of "presence or absence of fistula of the secondary palate" rather than the Pittsburgh Fistula Classification System.

Analytical methods were finalized and all analyses completed on shake flask tests with Indiana No. 5 and Pittsburgh No. 8 coal. A column leaching-rotating biological contractor (RBC) unit was used to bioleach pyrite and hazardous air pollutant precursors from Pittsburgh No. 8 coal. Shake flask tests with Rosebud subbituminous coal were begun. In connection with upcoming slurry column reactor tests, coal was prepared and shipped to INEL, and a detailed work plan was developed for operation and sampling for the tests. A manuscript and poster was prepared for presentation at the PETC contractors conference.

During the past year on Task A, the HELIOS work drew to a close with first results from the electron-muon pair studies (no anomalous sources are seen, and the final results and uncertainties are being set). First data from CMD2 will allow improvement of some phi branching ratios, including some improved limits on forbidden decays. The engineering run for E865 is scheduled for June and July of 1993. The principal efforts of Task B, the Fermilab program, have been the completion of the analysis of the 1987--88 data with resulting publications, completion of the 1990--91 data run, and the beginning of the analysis of the 1990--91 data. In addition, the Task B group is taking a leadership role in developing a proposal to Fermilab for the upgrade of the CDF silicon vertex detector in preparation for the 1995 data run. Task C has recently submitted results of its fractionally charged particle searches, placing new upper limits on the abundance of naturally-occurring fractionally-charged particles in various materials. This group has recently been approved by the Brookhaven management for an exposure of their p-i-n diodes in a high intensity proton beam. This measurement, along with its subsequent analysis, will complete the program. Task D concerned itself with silicon drift chamber studies for the SSC. Task E was devoted to studies of electronics for the GEM Level 1 liquid Ar calorimeter trigger
