    2003-01-01

    We prove that in a world without leverage cost the relationship between the levered beta ( L) and the unlevered beta ( u) is the No-costs-of-leverage formula: L = u + ( u - d) D (1 - T) / E. We also analyze 6 alternative valuation theories proposed in the literature to estimate the relationship between the levered beta and the unlevered beta (Harris and Pringle (1985), Modigliani and Miller (1963), Damodaran (1994), Myers (1974), Miles and Ezzell (1980), and practitioners) and prove that all ...

    The surficial and shallow subsurface geology of Harrison Bay on the Beaufort Sea coast was mapped as part of the U.S. Geological Survey's prelease evaluation for Outer Continental Shelf (OCS) Oil and Gas Lease Sale 71. During the 1980 summer season, approximately 1600 km of multisensored, high-resolution geophysical profile data were collected along a rectangular grid with 4.8 km line spacing. Interpretation of these data is presented on five maps showing bathymetry, sea-floor microrelief, ice-gouge characteristics, Holocene sediment thickness, and geologic structure to depths of approximately 1000 m. On a broad scale, the seafloor is shallow and almost flat, although microrelief features produced by sediment transport and ice-gouge processes typically vary up to several meters in amplitude. Microrelief bedforms related to hydraulic processes are predominant in water depths less than 12 m. Microrelief caused by ice gouging generally increases with water depth, reaching a maximum of 2 m or more in water depths beyond the 20 m isobath. This intensely gouged area lies beneath the shear zone between the seasonal landfast ice and the mobile polar ice pack. The thickness of recent (Holocene) sediment increases offshore, from 2 m near the Colville River delta to 30 m or more on the outer shelf. The thin Holocene layer is underlain by a complex horizon interpreted to be the upper surface of a Pleistocene deposit similar in composition to the present Arctic Coastal Plain. The base of the inferred Pleistocene section is interpreted to be a low-angle unconformity 100 m below sea level. Beneath this Tertiary-Quaternary unconformity, strata are interpreted to be alluvial fan-delta plain deposits corresponding to the Colville Group and younger formations of Late Cretaceous to Tertiary age. Numerous high-angle faults downthrown to the north trend across the survey area. With few exceptions, these faults terminate at or below the 100 m unconformity, suggesting that most tectonism

    Resumen

    En el último siglo la mítica ciudad de Nueva York ha sido capaz de definir y transmitir las más contagiosas propuestas de  construcción del futuro.
    El edificio de la Lever House, erigido en el corazón de Manhattan al comienzo de la prodigiosa década de los cincuenta, consiguió ser la constatación de que el perseguido sueño de la “torre de cristal” era por fin posible. La poética y secular conquista de la  levedad avanzó entonces a través de un prosaico y paradójico objeto publicitario. Un particular crisol de negocio, oportunidad y audacia hicieron de ésta sorprendente pieza un icono   fundamental de la globalizada arquitectura moderna americana.

    Abstract

    In the last century, the mythical city of New York has been able to define and transmit the most contagious proposals of  innovative construction.
    The Lever House Building, erected in the heart of Manhattan at  the start of the prodigious 1950s managed to become a  statement for the possibility of finally realizing the sought‐after
    dream of building a glass tower. The poetics and secular   conquest of lightness therefore made a leap forward through a prosaic and paradoxical publicity item. A special crucible of business, opportunity and audacity made a fundamental icon of globalized modern American Architecture out of this surprising work.

    2003-12-01

    Harrison Edward ``Harry" Radford, a noted laboratory spectroscopist and pioneer in the application of magnetic resonance techniques to spectroscopy, died on 5 May 2000, after a long battle with amyotropic lateral sclerosis (ALS). During a 37-year career at the National Bureau of Standards and the Smithsonian Astrophysical Observatory, Harry measured the frequencies of numerous molecular transitions which aided the emerging field of astrochemistry. Harry was both an excellent theoretician and a preeminently skilled experimentalist. He has several major spectroscopic achievements to his credit. He performed the first study of a short-lived molecular free radical, OH, by electron paramagnetic resonance spectroscopy, opening up a huge and important field of research. Together with colleagues he made the first observation of the rotational spectrum of CH by far infrared laser magnetic resonance spectroscopy and extended the technique to other molecules such as CH3O. Harry was born in Peterborough, New Hampshire, on 26 July 1927. He was the son of Harrison Edwin Radford, a roofer, and Dorothy (née Cole) Radford. He dropped out of high school to join the Navy in 1944 as an electronics technician's mate. After his discharge in 1946 he worked in the family construction business for four years as a roofer. In 1950 he entered the University of New Hampshire and graduated four years later, Summa Cum Laude, with a degree in physics. As a graduate student at Yale from 1954 to 1959 he wrote his PhD thesis under the supervision of V.W. Hughes on the microwave Zeeman spectra of oxygen and fluorine where he used the technique of paramagnetic resonance absorption in atomic vapors. In 1954 he married Mildred Spofford. They had three daughters, Susan (born in 1955), Amy (1957), and Sarah (1960). In 1974 he married Alfa Goldthwaithe Morrison, who survived him. From 1959 until 1969 Harry worked at the National Bureau of Standards (now the National Institute of Standards and Technology

  13. Obituary: Edward R. (Ted) Harrison, 1919-2007

    Science.gov (United States)

    Irvine, William M.; Arny, Thomas T.; Trimble, Virginia

    2007-12-01

    Cosmologist Edward R. (Ted) Harrison, emeritus Distinguished University Professor of Physics and Astronomy at the University of Massachusetts Amherst, died on 29 January 2007 in his retirement city of Tucson, Arizona, where he was adjunct professor at the Steward Observatory, University of Arizona. The cause of death was colon cancer. He is survived by a sister, brother, and daughter. (A son died in 2000.) Perhaps best known for his work on the growth of fluctuations in the expanding universe and his books on cosmology for the dedicated layperson, Ted had extremely broad interests, and he published more than 200 papers in space sciences, plasma physics, high-energy physics, physical chemistry, and, principally, many aspects of astrophysics. He was a Fellow of the American Physical Society, the American Association for the Advancement of Science, the Royal Astronomical Society, and the Institute of Physics (UK). Ted Harrison was born 8 January 1919 in London, England. His parents were Robert Harrison and Daisy Harrison (nee White). His education at Sir John Cass College, London University, was interrupted by the Second World War, during which he served for six years with the British Army in various campaigns, ultimately acting as Radar Adviser to the Northern Area of the Egyptian Army. It was during the latter service that he met his wife Photeni (nee Marangas). Following the War, Ted became a British Civil Servant, at first with the Atomic Energy Research Establishment in Harwell and then at the Rutherford High Energy Laboratory. During this period he acquired the equivalent of university degrees, becoming a graduate, then an Associate, and finally a Fellow of the Institute of Physics. His somewhat unorthodox education may have contributed to his broad interests and his very intuitive and physical approach to scientific problems. The latter became the bane of generations of graduate students, who might find themselves asked on their physics qualifying exams to

    Lever-propelled wheelchairs have been described as more efficient and less physically demanding than hand-rim-propelled wheelchairs. To evaluate a newly designed lever mechanism (MARC) in both one- and two-arm use, a series of wheelchair exercise tests were performed on a motor-driven treadmill.

  15. Health as a lever for another development.

    1978-01-01

    In India the health services are unable to meet the real needs of the poor. The colonial policy of exploitation, expropriation and plunder created widespread disruption in the way of life of the Indian people. The colonialism destroyed the health culture of India and created a Western bias in the health services which continues to this day. The bias has extend to research - for example, by postulating a correlation between malnutrition and mental retardation. The commitment of the current political leadership to bypass the medical establishment and go directly to the people has created a favorable setting to challenge the basic scientific, sociological and economic premises of the earlier approach to development of the health services in India, and to formulate a new approach to development of the health services in India, and to formulate a new approach to take its place. The main premise of Another Development in the health services is to begin with the people - a framework is designed for a health service system particularly tailored to meet the needs of the people. Efforts to relieve the suffering caused by health problems can contribute to the initiation of political, economic and social action. In this context, the formulation and implementation of Another Development in Health acquires much significance: 1) the very alleviation of suffering has political significance, because it narrows the gap between the ruling classes and the masses; 2) Another Development in Health would provide an entry point for change agents, who could use the opportunity to work with the people to initiate changes in other social and economic fields; and 3) by generating social awareness, Another Development in Health may work as a lever for promoting similar developments in other social and economic fields.

    Atomic force microscopes typically require knowledge of the cantilever spring constant and optical lever sensitivity in order to accurately determine the force from the cantilever deflection. In this study, we investigate a technique to calibrate the optical lever sensitivity of rectangular cantilevers that does not require contact to be made with a surface. This noncontact approach utilizes the method of Sader et al. [Rev. Sci. Instrum. 70, 3967 (1999)] to calibrate the spring constant of the cantilever in combination with the equipartition theorem [J. L. Hutter and J. Bechhoefer, Rev. Sci. Instrum. 64, 1868 (1993)] to determine the optical lever sensitivity. A comparison is presented between sensitivity values obtained from conventional static mode force curves and those derived using this noncontact approach for a range of different cantilevers in air and liquid. These measurements indicate that the method offers a quick, alternative approach for the calibration of the optical lever sensitivity

    2009-10-01

    Full Text Available This article deals with Harrison Birtwistle’s opera Gawain (1991. Written on a libretto by the English poet, David Harsent, Gawain is characterized both by national and extra-national elements. The most obvious national features are to be found in the subject of the opera based on the famous English medieval epic poem Sir Gawain and the Green Knight. They are also displayed in the references to Shakespeare, to other British composers (Michael Tippett and Henry Purcell for instance and to typical English musical or musico-dramatic forms such as the masque. As far as the foreign borrowings or influences are concerned, Harrison Birtwistle’s debt to composers like Richard Wagner, Igor Stravinsky and Olivier Messiaen is once more displayed in Gawain. Other influences are shown through his translation into music of aesthetic ideas inspired by the great German painter Paul Klee and through his adaptation of elements taken from Greek tragedy. One can thus wonder if this fusion or juxtaposition of vernacular and foreign elements is not one of the key features of Gawain.

    Observed neutrino mixing can be described by a tribimaximal MNS matrix. The resulting neutrino mass matrix in the basis of a diagonal charged lepton mass matrix is both 2-3 symmetric and magic. By a magic matrix, I mean one whose row sums and column sums are all identical. I study what happens if 2-3 symmetry is broken but the magic symmetry is kept intact. In that case, the mixing matrix is parameterized by a single complex parameter U e3 , in a form discussed recently by Bjorken, Harrison, and Scott

  9. Change in hippocampal theta oscillation associated with multiple lever presses in a bimanual two-lever choice task for robot control in rats.

    Directory of Open Access Journals (Sweden)

    Norifumi Tanaka

    Full Text Available Hippocampal theta oscillations have been implicated in working memory and attentional process, which might be useful for the brain-machine interface (BMI. To further elucidate the properties of the hippocampal theta oscillations that can be used in BMI, we investigated hippocampal theta oscillations during a two-lever choice task. During the task body-restrained rats were trained with a food reward to move an e-puck robot towards them by pressing the correct lever, ipsilateral to the robot several times, using the ipsilateral forelimb. The robot carried food and moved along a semicircle track set in front of the rat. We demonstrated that the power of hippocampal theta oscillations gradually increased during a 6-s preparatory period before the start of multiple lever pressing, irrespective of whether the correct lever choice or forelimb side were used. In addition, there was a significant difference in the theta power after the first choice, between correct and incorrect trials. During the correct trials the theta power was highest during the first lever-releasing period, whereas in the incorrect trials it occurred during the second correct lever-pressing period. We also analyzed the hippocampal theta oscillations at the termination of multiple lever pressing during the correct trials. Irrespective of whether the correct forelimb side was used, the power of hippocampal theta oscillations gradually decreased with the termination of multiple lever pressing. The frequency of theta oscillation also demonstrated an increase and decrease, before and after multiple lever pressing, respectively. There was a transient increase in frequency after the first lever press during the incorrect trials, while no such increase was observed during the correct trials. These results suggested that hippocampal theta oscillations reflect some aspects of preparatory and cognitive neural activities during the robot controlling task, which could be used for BMI.

  11. Synthesis of lever-blade dampers with enhanced mechanical structure

    Directory of Open Access Journals (Sweden)

    Igor I. Sydorenko

    2015-03-01

    Full Text Available Since the torsion bar represents just an elastic element, the energy dissipation in suspensions problem is highly relevant for its application. Currently in quality of a dissipation device in torsion suspension are used the hydraulic dampers with movable members reciprocating translational motion respectively to the housing or lever-type hydraulic shock absorbers of piston and vane types, with the movable member’s rotational movement respectively to the housing. These dampers are implementing only throttle-valve performance type, associated with these devices’ functional capacities and depending on design constraints. The paper presents a synthesis of innovative lever-blade dampers, whose performance is not related to the value of working chambers inner pressure. Their essential peculiarity relates to the mechanical control loop presence in the structure that determines a close relationship between the performance and the value of the shock absorber movable element displacement relatively to the body. In the process of synthesis carried out tested are the appropriate methods, built on the basis of technical systems’ modeling with modified kinematic graphs. The synthesis results are shown in the form of two structurally implemented samples. Performed is a comparative analysis of the samples with their basic performance determining.

    In this work we report the analysis of typical errors arising from an Andrade-Chalmers lever cam, used as machine for mechanical constant stress tests. A procedure to obtain the magnitude of the applied stress as a function of the rotation of the lever arm was developed by used a mechanism which allow us to simulate the sample deformation. The used physical mechanism involves LVDT and Load Cell transducers. The characteristic parameters of the lever arm were founded using a least squares criterion procedure on the digitalized values of transducers signals. The departure existing between an actual lever and ideal one was fully analyzed. (Author) 18 refs

    Over the past two decades, mental health reform in Australia has received unprecedented government attention. This study explored how five policy levers (organisation, regulation, community education, finance and payment) were used by the Australian Federal Government to implement mental health reforms. Australian Government publications, including the four mental health plans (published in 1992, 1998, 2003 and 2008) were analysed according to policy levers used to drive reform across five priority areas: [1] human rights and community attitudes; [2] responding to community need; [3] service structures; [4] service quality and effectiveness; and [5] resources and service access. Policy levers were applied in varying ways; with two or three levers often concurrently used to implement a single initiative or strategy. For example, changes to service structures were achieved using various combinations of all five levers. Attempts to improve service quality and effectiveness were instead made through a single lever-regulation. The use of some levers changed over time, including a move away from prescriptive, legislative use of regulation, towards a greater focus on monitoring service standards and consumer outcomes. Patterns in the application of policy levers across the National Mental Health Strategy, as identified in this analysis, represent a novel way of conceptualising the history of mental health reform in Australia. An improved understanding of the strategic targeting and appropriate utilisation of policy levers may assist in the delivery and evaluation of evidence-based mental health reform in the future.

  14. Symmetry Analysis of Gauge-Invariant Field Equations via a Generalized Harrison-Estabrook Formalism.

    Science.gov (United States)

    Papachristou, Costas J.

    The Harrison-Estabrook formalism for the study of invariance groups of partial differential equations is generalized and extended to equations that define, through their solutions, sections on vector bundles of various kinds. Applications include the Dirac, Yang-Mills, and self-dual Yang-Mills (SDYM) equations. The latter case exhibits interesting connections between the internal symmetries of SDYM and the existence of integrability characteristics such as a linear ("inverse scattering") system and Backlund transformations (BT's). By "verticalizing" the generators of coordinate point transformations of SDYM, nine nonlocal, generalized (as opposed to local, point) symmetries are constructed. The observation is made that the prolongations of these symmetries are parametric BT's for SDYM. It is thus concluded that the entire point group of SDYM contributes, upon verticalization, BT's to the system.

    Thermodynamic properties such as entropy, specific heat capacity at constant pressure and isothermal compressibility have been calculated for liquid 3d, 4d and 5d transition metals near melting temperature. The hard sphere diameter for all such systems is estimated from the potential profile generated from the Wills and Harrison's prescription using linearized WCA theory of liquid. Evaluated values of entropy and specific heat capacity are found to be in good agreement with the experimental data. Transport property like shear viscosity for these liquid metals is obtained using the same potential profile. Lack of experimental data at melting temperatures hampers detailed comparison for all such systems. However, for the case of transport property, the results obtained are found to compare qualitatively well with the available experimental data. (author)

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at a Montana Army National Guard (MTARNG) property near Helena, Montana. Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing preremedial activities and to provide a basis for establishing corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining site activities, quantities of hazardous substances present, and potential pathways by which contamination could affect public health and the environment. This PA satisfies, for the Fort William Henry Harrison property, requirements of the Department of Defense Installation Restoration Program

    Using the Harrison model and Green's function technique, impurity doping effects on the orbital density of states (DOS), electronic heat capacity (EHC) and magnetic susceptibility (MS) of a monolayer hydrogenated graphene, chair-like graphane, are investigated. The effect of scattering between electrons and dilute charged impurities is discussed in terms of the self-consistent Born approximation. Our results show that the graphane is a semiconductor and its band gap decreases with impurity. As a remarkable point, comparatively EHC reaches almost linearly to Schottky anomaly and does not change at low temperatures in the presence of impurity. Generally, EHC and MS increases with impurity doping. Surprisingly, impurity doping only affects the salient behavior of py orbital contribution of carbon atoms due to the symmetry breaking.

    Background: Diagnosing an anterior cruciate ligament (ACL) rupture based on a physical examination remains a challenge for both surgeons and physical therapists. The lever sign test was developed to overcome the practical limitations of other tests and to optimize diagnosis. An evaluation of the measurement properties of the lever sign test is needed to make adequate interpretations in practice. Purpose: To evaluate the reliability and diagnostic value of the lever sign test. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 94 patients were recruited between November 2014 and July 2016. Patients were included if they were at least 16 years old, suffered from knee trauma, and had indications for knee arthroscopic surgery. Lever sign, anterior drawer, Lachman, and pivot-shift test outcomes were examined by an orthopaedic/trauma surgeon and a physical therapist. A test-retest design was used to investigate interrater reliability. Moreover, the lever sign test outcomes, alone and in combination with the other diagnostic tests, were compared with arthroscopic results, which served as the gold standard for the test’s diagnostic value. Results: The lever sign test and pivot-shift test had kappa values exceeding 0.80 for interrater reliability. The kappa values for the anterior drawer test and Lachman test were 0.80 and 0.77, respectively. The lever sign test showed the highest specificity (100%) and the lowest sensitivity (39%) when compared with the other 3 tests. Moreover, its positive and negative predictive values were 100% and 65%, respectively, while an accuracy of 71% was calculated. Clustering the lever sign test parallel with the other 3 tests resulted in the highest accuracy of 91%. Conclusion: The lever sign test appears to have high interrater reliability and is the most specific test, showing a maximal positive predictive value. A positive lever sign test result indicates an ACL rupture. These results support the added value

    Introducing change is a difficult issue facing all health care systems. The use of various clinical governance levers can facilitate change in health care systems. The purpose of this paper is to define clinical governance levers, and to illustrate their use in a large-scale transformation. The empirical analysis deals with the in-depth study of a specific case, which is the organizational model for Ontario's cancer sector. The authors used a qualitative research strategy and drew the data from three sources: semi-structured interviews, analysis of documents, and non-participative observations. From the results, the authors identified three phases and several steps in the reform of cancer services in this province. The authors conclude that a combination of clinical governance levers was used to transform the system. These levers operated at different levels of the system to meet the targeted objectives. To exercise clinical governance, managers need to acquire new competencies. Mobilizing clinical governance levers requires in-depth understanding of the role and scope of clinical governance levers. This study provides a better understanding of clinical governance levers. Clinical governance levers are used to implement an organizational environment that is conducive to developing clinical practice, as well as to act directly on practices to improve quality of care.

    Betts, Jonathan

    2006-09-01

    This is the story of Rupert T. Gould (1890-1948), the polymath and horologist. A remarkable man, Lt Cmdr Gould made important contributions in an extraordinary range of subject areas throughout his relatively short and dramatically troubled life. From antique clocks to scientific mysteries, from typewriters to the first systematic study of the Loch Ness Monster, Gould studied and published on them all. With the title The Stargazer, Gould was an early broadcaster on the BBC's Children's Hour when, with his encyclopaedic knowledge, he became known as The Man Who Knew Everything. Not surprisingly, he was also part of that elite group on BBC radio who formed The Brains Trust, giving on-the-spot answers to all manner of wide ranging and difficult questions. With his wide learning and photographic memory, Gould awed a national audience, becoming one of the era's radio celebrities. During the 1920s Gould restored the complex and highly significant marine timekeepers constructed by John Harrison (1693-1776), and wrote the unsurpassed classic, The Marine Chronometer, its History and Development . Today he is virtually unknown, his horological contributions scarcely mentioned in Dava Sobel's bestseller Longitude. The TV version of Longitude, in which Jeremy Irons played Rupert Gould, did at least introduce Gould's name to a wider public. Gould suffered terrible bouts of depression, resulting in a number of nervous breakdowns. These, coupled with his obsessive and pedantic nature, led to a scandalously-reported separation from his wife and cost him his family, his home, his job, and his closest friends. In this first-ever biography of Rupert Gould, Jonathan Betts, the Royal Observatory Greenwich's Senior Horologist, has given us a compelling account of a talented but flawed individual. Using hitherto unknown personal journals, the family's extensive collection of photographs, and the polymath's surviving records and notes, Betts tells the story of how Gould's early life, his

  5. Deviations of the lepton mapping matrix form the harrison-perkins-scott form

    Friedberg, R.; Lee, T.D.

    2010-01-01

    We propose a simple set of hypotheses governing the deviations of the leptonic mapping matrix from the Harrison-Perkins-Scott (HPS) form. These deviations are supposed to arise entirely from a perturbation of the mass matrix in the charged lepton sector. The perturbing matrix is assumed to be purely imaginary (thus maximally T-violating) and to have a strength in energy scale no greater (but perhaps smaller) than the muon mass. As we shall show,it then follows that the absolute value of the mapping matrix elements pertaining to the tau lepton deviate by no more than O((m μ /m τ ) 2 ) ≅ 3.5 x 10 -3 from their HPS values. Assuming that(m μ /m τ ) 2 can be neglected, we derive two simple constraints on the four parameters θ12, θ23, θ31, and δ of the mapping matrix. These constraints are independent of the details of the imaginary T-violating perturbation of the charged lepton mass matrix. We also show that the e and μ parts of the mapping matrix have a definite form governed by two parameters α and β; any deviation of order m μ /m τ can be accommodated by adjusting these two parameters.

    The risk of an oil spill resulting from the development of the Alpine oil field is considered to be low. The field is located on the North Slope of Alaska adjacent to the Alaskan Beaufort Sea and reaches coastal waters from the distributary channels of the Colville River Delta. The physical environmental (hydrodynamic) conditions that would affect the transport and fate of spilled oil was investigated to further reduce the risk. During the open-water season of 2001 in Harrison Bay, near shore current meters were deployed and data on weather and surface currents was analyzed. Ocean current and wind measurements were examined to evaluate the relationship between meteorology and water levels during the open-water season. The objective was to gain a better understanding of the near shore hydrodynamic processes at play in Harrison Bay, in order to plan the most appropriate spill response strategies. The results obtained indicate that surface currents within the bay adjacent to the Colville Delta are variable. They respond to wind forces as well as other possible mechanisms like estuarine circulation. The surface currents reach maximum speeds of 0.26 metre per second. For the late July-September deployment, the calculated net surface drift was a 0.02 metre per second current to the east southeast. In both Harrison Bay and Colville Delta, prevailing southwest and northeast winds, respectively, induced water level changes of more than 0.5 metre above and below the average. 7 refs., 3 tabs., 7 figs

    Geometric dimensions of the basic elements of a core lifter should be determined depending on the clamping conditions. The changes should be determined depending on the conditions of the core sample diameter, critical angle between the lever and the core samples in the necessary depth of submersion of the contact edge of the lever into its surface. The core lifter KTsRZ-80 with eccentric core reception makes it possible to arrange more efficiently the core removing elements on the edge of the band. The use of the core lifters with eccentric plan of arrangement of the levers and their optimal length increases the removal of the core sample.

    The fully instrumented Resen Waves Lever Operated Pivoting Float LOPF wave energy buoy model has gone through the first stage of testing in regular waves in scale 1:25 of the North Sea wave conditions, in the 3D deep wave basin at the Hydraulic and Coastal Engineering Laboratory of Aalborg University in Denmark. The model size was 60cm W x 90cm L x 21cm H. The 60 cm width pointed towards the wave front. The LOPF buoy is characterized by a simple mechanical design with few moving parts and direct electrical output and it is taut moored to the sea bed, so all forces are referenced to the seabed for maximum energy output in regular as well as irregular waves. During storms the buoy pivots and streamlines itself to minimize loads on the mooring line. A conservative estimate shows that a full scale system for North Sea conditions has a float size width of 15 m that will, with 60% generator efficiency, produce 610 MWh/y (609.497 kWh/y) with an average power output of 69.6 kW, which requires a generator capacity of 700 kW. It is expected the generator efficiency can be increased to 90% in the future. More specific calculations (from EnergiNet) show that with one generator of 695 kW the expected power production is 585 MWh/y; with a generator of 250 kW and 100 kW, the expected power production is 481 MWh/y and 182 MWh/y respectively. In addition there are several areas for future improvements for increased power production. (Author)

  9. The Effects of Lever Arm (Instrument Offset) Error on GRAV-D Airborne Gravity Data

    High quality airborne gravity collection with a 2-axis, stabilized platform gravity instrument, such as with a Micro-g LaCoste Turnkey Airborne Gravity System (TAGS), is dependent on the aircraft's ability to maintain "straight and level" flight. However, during flight there is constant rotation about the aircraft's center of gravity. Standard practice is to install the scientific equipment close to the aircraft's estimated center of gravity to minimize the relative rotations with aircraft motion. However, there remain small offsets between the instruments. These distance offsets, the lever arm, are used to define the rigid-body, spatial relationship between the IMU, GPS antenna, and airborne gravimeter within the aircraft body frame. The Gravity for the Redefinition of the American Vertical Datum (GRAV-D) project, which is collecting airborne gravity data across the U.S., uses a commercial software package for coupled IMU-GNSS aircraft positioning. This software incorporates a lever arm correction to calculate a precise position for the airborne gravimeter. The positioning software must do a coordinate transformation to relate each epoch of the coupled GNSS-IMU derived position to the position of the gravimeter within the constantly-rotating aircraft. This transformation requires three inputs: accurate IMU-measured aircraft rotations, GNSS positions, and lever arm distances between instruments. Previous studies show that correcting for the lever arm distances improves gravity results, but no sensitivity tests have been done to investigate how error in the lever arm distances affects the final airborne gravity products. This research investigates the effects of lever arm measurement error on airborne gravity data. GRAV-D lever arms are nominally measured to the cm-level using surveying equipment. "Truth" data sets will be created by processing GRAV-D flight lines with both relatively small lever arms and large lever arms. Then negative and positive incremental

    The infralimbic cortex (IL) mediates extinction learning and the active suppression of cocaine-seeking behavior. However, the precise temporal relationship among IL activity, lever pressing, and extinction learning is unclear. To address this issue, we used activity-guided optogenetics in male Sprague Dawley rats to silence IL pyramidal neurons optically for 20 s immediately after unreinforced lever presses during early extinction training after cocaine self-administration. Optical inhibition of the IL increased active lever pressing during shortened extinction sessions, but did not alter the retention of the extinction learning as assessed in ensuing extinction sessions with no optical inhibition. During subsequent cued reinstatement sessions, rats that had previously received optical inhibition during the extinction sessions showed increased cocaine-seeking behavior. These findings appeared to be specific to inhibition during the post-lever press period because IL inhibition given in a noncontingent, pseudorandom manner during extinction sessions did not produce the same effects. Illumination alone (i.e., with no opsin expression) and food-seeking control experiments also failed to produce the same effects. In another experiment, IL inhibition after lever presses during cued reinstatement sessions increased cocaine seeking during those sessions. Finally, inhibition of the prelimbic cortex immediately after unreinforced lever presses during shortened extinction sessions decreased lever pressing during these sessions, but had no effect on subsequent reinstatement. These results indicate that IL activity immediately after unreinforced lever presses is necessary for normal extinction of cocaine seeking, suggesting that critical encoding of the new contingencies between a lever press and a cocaine reward occurs during that period. SIGNIFICANCE STATEMENT The infralimbic cortex (IL) contributes to the extinction of cocaine-seeking behavior, but the precise relationship

    Neutral cues paired with rewards often appear to acquire motivational significance, as if the incentive motivational value of the reward is transferred to the cue. Such cues have been reported to modulate the performance of instrumental action (Pavlovian-instrumental transfer, PIT), serve as conditioned reinforcers in the establishment of new learning, and be the targets of approach and other cue-directed behaviors. Here we examined the effects of lesions of the amygdala central nucleus (CeA) on the acquisition of discriminative autoshaped lever-pressing. Insertion of one lever into the experimental chamber was reinforced by sucrose delivery, but insertion of another lever was not reinforced. Although sucrose delivery was not contingent on lever pressing, both CeA- and sham-lesioned rats rapidly came to press the reinforced but not the nonreinforced lever. Despite their showing little evidence of impairments in autoshaped lever pressing, these same CeA-lesioned rats showed significant deficits in the expression of PIT in a subsequent phase of the experiment. The lack of impaired autoshaping in CeA-lesioned rats contrasts with effects previously reported for conditioned orienting responses (ORs) and for other putative measures of incentive learning including PIT and conditioned approach to visual cues.

  12. What role does performance information play in securing improvement in healthcare? a conceptual framework for levers of change.

    Science.gov (United States)

    Levesque, Jean-Frederic; Sutherland, Kim

    2017-08-28

    Across healthcare systems, there is consensus on the need for independent and impartial assessment of performance. There is less agreement about how measurement and reporting performance improves healthcare. This paper draws on academic theories to develop a conceptual framework-one that classifies in an integrated manner the ways in which change can be leveraged by healthcare performance information. A synthesis of published frameworks. The framework identifies eight levers for change enabled by performance information, spanning internal and external drivers, and emergent and planned processes: (1) cognitive levers provide awareness and understanding; (2) mimetic levers inform about the performance of others to encourage emulation; (3) supportive levers provide facilitation, implementation tools or models of care to actively support change; (4) formative levers develop capabilities and skills through teaching, mentoring and feedback; (5) normative levers set performance against guidelines, standards, certification and accreditation processes; (6) coercive levers use policies, regulations incentives and disincentives to force change; (7) structural levers modify the physical environment or professional cultures and routines; (8) competitive levers attract patients or funders. This framework highlights how performance measurement and reporting can contribute to eight different levers for change. It provides guidance into how to align performance measurement and reporting into quality improvement programme. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Farreras, Ingrid G

    2014-11-01

    The first law providing for the commitment of "feeble-minded" individuals in the United States was passed in 1915, in the state of Illinois. House Bill 655 not only allowed for the permanent, involuntary institutionalization of feeble-minded individuals, but it shifted the commitment and discharge authority from the institution superintendents to the courts. Clara Harrison Town, a student of Lightner Witmer, and the state psychologist at the second largest institution for feeble-minded individuals in the country, was instrumental in this law passing and in ensuring that psychologists, for the first time, be viewed as court "experts" when testifying as to the feeble mindedness of individuals.

    The purpose of this study was to (1) evaluate the mechanical efficiency (ME) of two commercially available lever-propulsion mechanisms for wheelchairs and (2) compare the ME of lever propulsion with hand rim propulsion within the same wheelchair. Of the two mechanisms, one contained a torsion spring while the other used a roller clutch design. We hypothesized that the torsion spring mechanism would increase the ME of propulsion due to a passive recovery stroke enabled by the mechanism. Ten nondisabled male participants with no prior manual wheeling experience performed submaximal exercise tests using both lever-propulsion mechanisms and hand rim propulsion on two different wheelchairs. Cardiopulmonary parameters including oxygen uptake (VO2), heart rate (HR), and energy expenditure (En) were determined. Total external power (Pext) was measured using a drag test protocol. ME was determined by the ratio of Pext to En. Results indicated no significant effect of lever-propulsion mechanism for all physiological measures tested. This suggests that the torsion spring did not result in a physiological benefit compared with the roller clutch mechanism. However, both lever-propulsion mechanisms showed decreased VO2 and HR and increased ME (as a function of slope) compared with hand rim propulsion (p propulsion mechanisms tested are more mechanically efficient than conventional hand rim propulsion, especially when slopes are encountered.

    An equivalent circuit model for the design and analysis of two-section gain lever quantum dot (QD) laser is presented. This model is based on the three level rate equations with two independent carrier populations and a single longitudinal optical mode. By using the presented model, the effect of gain lever on QD laser performances is investigated. The results of simulation show that the main characteristics of laser such as threshold current, transient response, output power and modulation response are affected by differential gain ratios between the two-sections

    2000-01-01

    During a Shuttle flight in the early part of 1999, one of the crewmembers was unable to operate the backrest lever for the light-weight seat in microgravity. It is essential that the crewmembers are able to adjust this back-rest lever, which is titled forward 2 degrees from vertical during launch and then moved backwards to 10 degrees aft of vertical upon reaching orbit. This adjustment is needed to cushion the crewmembers during an inadvertent crash landing situation. The original Shuttle seats, which had seat controls located on the front left and right sides of the seat, were replaced recently with the new light-weight seats. The controls for these new, seats were moved to the night side with one control at the front and the other at the back. While it was uncertain whether the problem encountered was unique to that crewmember or not it was clear to the personnel responsible for maintaining the Shuttle seats that not knowing the cause of the problem posed a safety concern for NASA. Hence the Anthropometry and Biomechanics Facility (ABF) of the Johnson Space Center was requested to perform an evaluation of the seat controls and provide NASA with appropriate recommendations on whether the seat lever positions and operations should be modified. The ABF designed an experiment to investigate the amount of pull force exerted by subjects, wearing an unpressurized or pressurized crew launch escape suit, when controls were placed in the front and back (on the right side) of the light-weight seat. Single-axis load cells were attached to the seat levers, which measured the maximum static pull forces that were exerted by the subjects. Twelve subjects, six male and six female, participated in this study. Each subject was asked to perform the pull test at least three times for each combination of lever position and suit pressure conditions. The results from this study showed that as a whole (or in general), the subjects were able to pull on the lever at the back position with

    This paper makes persuasive demonstrations on some problems about the human ear sound transmission principle in existing physiological textbooks and reference books, and puts forward the authors' view to make up for its literature. Exerting the knowledge of lever in physics and the acoustics theory, we come up with an equivalent simplified model of manubrium mallei which is to meet the requirements as the long arm of the lever. We also set up an equivalent simplified model of ossicular chain--a combination of levers of ossicular chain. We disassemble the model into two simple levers, and make full analysis and demonstration on them. Through the calculation and comparison of displacement amplitudes in both external auditory canal air and internal ear lymph, we may draw a conclusion that the key reason, which the sound displacement amplitude is to be decreased to adapt to the endurance limit of the basement membrane, is that the density and sound speed in lymph is much higher than those in the air.

    Previously established individual differences in appetitive approach and devaluation sensitivity observed in goal- and sign-trackers may be attributed to differences in the acquisition, modification, or use of associative information in basolateral amygdala (BLA) pathways. Here, we sought to determine the extent to which communication of associative information between BLA and anterior portions of insular cortex (IC) supports ongoing Pavlovian conditioned approach behaviors in sign- and goal-tracking rats, in the absence of manipulations to outcome value. We hypothesized that the BLA mediates goal-, but not sign- tracking approach through interactions with the IC, a brain region involved in supporting flexible behavior. We first trained rats in Pavlovian lever autoshaping to determine their sign- or goal-tracking tendency. During alternating test sessions, we gave unilateral intracranial injections of vehicle or a cocktail of gamma-aminobutyric acid (GABA) receptor agonists, baclofen and muscimol, unilaterally into the BLA and contralaterally or ipsilaterally into the IC prior to reinforced lever autoshaping sessions. Consistent with our hypothesis we found that contralateral inactivation of BLA and IC increased the latency to approach the food cup and decreased the number of food cup contacts in goal-trackers. While contralateral inactivation of BLA and IC did not affect the total number of lever contacts in sign-trackers, this manipulation increased the latency to approach the lever. Ipsilateral inactivation of BLA and IC did not impact approach behaviors in Pavlovian lever autoshaping. These findings, contrary to our hypothesis, suggest that communication between BLA and IC maintains a representation of initially learned appetitive associations that commonly support the initiation of Pavlovian conditioned approach behavior regardless of whether it is directed at the cue or the location of reward delivery.

    A cue associated with a rewarding event can trigger behavior towards the cue itself due to the cue acquiring incentive value through its pairing with the rewarding outcome (i.e., sign-tracking). For example, rats will approach, press, and attempt to "consume" a retractable lever conditioned stimulus (CS) that signals delivery of a food unconditioned stimulus (US). Attending to food-predictive CSs is important when seeking out food, and it is just as important to be able to modify one's behavior when the relationships between CSs and USs are changed. Using a discriminative autoshaping procedure with lever CSs, the present study investigated the effects of orbitofrontal cortex (OFC) lesions on sign-tracking and reversal learning. Insertion of one lever was followed by sucrose delivery upon retraction, and insertion of another lever was followed by nothing. After the acquisition phase, the contingencies between the levers and outcomes were reversed. Bilateral OFC lesions had no effect on the acquisition of sign-tracking. However, OFC-lesioned rats showed substantial deficits in acquiring sign-tracking compared to sham-lesioned rats once the stimulus-outcome contingencies were reversed. Over the course of reversal learning, OFC-lesioned rats were able to reach comparable levels of sign-tracking as sham-lesioned rats. These findings suggest that OFC is not necessary for the ability of a CS to acquire incentive value and provide more evidence that OFC is critical for modifying behavior appropriately following a change in stimulus-outcome contingencies.

    A method using atomic force microscope (AFM) optical levers and a reference nanopositioning stage has been developed to characterize piezoscanner hysteresis and creep. The piezoscanner is fixed on a closed-loop nanopositioning stage, both of which have the same arrangement on each axis of the three spatial directions inside the AFM-based nanomanipulation system. In order to achieve characterization, the optical lever is used as a displacement sensor to measure the relative movement between the nanopositioning stage and the piezoscanner by lateral tracking a well-defined slope with the tapping mode of the AFM cantilever. This setup can be used to estimate a piezoscanner's voltage input with a reference displacement from the nanopositioning stage. The hysteresis and creep were accurately calibrated by the method presented, which use the current setup of the AFM-based nanomanipulation system without any modification or additional devices.

    Full Text Available An important unresolved problem associated with actomyosin motors is the role of Brownian motion in the process of force generation. On the basis of structural observations of myosins and actins, the widely held lever-arm hypothesis has been proposed, in which proteins are assumed to show sequential structural changes among observed and hypothesized structures to exert mechanical force. An alternative hypothesis, the Brownian motion hypothesis, has been supported by single-molecule experiments and emphasizes more on the roles of fluctuating protein movement. In this study, we address the long-standing controversy between the lever-arm hypothesis and the Brownian motion hypothesis through in silico observations of an actomyosin system. We study a system composed of myosin II and actin filament by calculating free-energy landscapes of actin-myosin interactions using the molecular dynamics method and by simulating transitions among dynamically changing free-energy landscapes using the Monte Carlo method. The results obtained by this combined multi-scale calculation show that myosin with inorganic phosphate (Pi and ADP weakly binds to actin and that after releasing Pi and ADP, myosin moves along the actin filament toward the strong-binding site by exhibiting the biased Brownian motion, a behavior consistent with the observed single-molecular behavior of myosin. Conformational flexibility of loops at the actin-interface of myosin and the N-terminus of actin subunit is necessary for the distinct bias in the Brownian motion. Both the 5.5-11 nm displacement due to the biased Brownian motion and the 3-5 nm displacement due to lever-arm swing contribute to the net displacement of myosin. The calculated results further suggest that the recovery stroke of the lever arm plays an important role in enhancing the displacement of myosin through multiple cycles of ATP hydrolysis, suggesting a unified movement mechanism for various members of the myosin family.

    This paper presents theoretical and experimental results on the investigation of the dynamics of a nonlinear electromechanical system made of a lever arm actuated by a DC motor and controlled through a repulsive magnetic force. We use the method of harmonic balance to derive oscillatory solutions. Theoretical tools such as, bifurcation diagrams, Lyapunov exponents, phase portraits, are used to unveil the rich nonlinear behavior of the system including chaos and hysteresis. The experimental results are in close accordance with the theoretical predictions.

  9. The jaw is a second-class lever in Pedetes capensis (Rodentia: Pedetidae

    Full Text Available The mammalian jaw is often modelled as a third-class lever for the purposes of biomechanical analyses, owing to the position of the resultant muscle force between the jaw joint and the teeth. However, it has been proposed that in some rodents the jaws operate as a second-class lever during distal molar bites, owing to the rostral position of the masticatory musculature. In particular, the infraorbital portion of the zygomatico-mandibularis (IOZM has been suggested to be of major importance in converting the masticatory system from a third-class to a second-class lever. The presence of the IOZM is diagnostic of the hystricomorph rodents, and is particularly well-developed in Pedetes capensis, the South African springhare. In this study, finite element analysis (FEA was used to assess the lever mechanics of the springhare masticatory system, and to determine the function of the IOZM. An FE model of the skull of P. capensis was constructed and loaded with all masticatory muscles, and then solved for biting at each tooth in turn. Further load cases were created in which each masticatory muscle was removed in turn. The analyses showed that the mechanical advantage of the springhare jaws was above one at all molar bites and very close to one during the premolar bite. Removing the IOZM or masseter caused a drop in mechanical advantage at all bites, but affected strain patterns and cranial deformation very little. Removing the ZM had only a small effect on mechanical advantage, but produced a substantial reduction in strain and deformation across the skull. It was concluded that the masticatory system of P. capensis acts as a second class lever during bites along almost the entire cheek tooth row. The IOZM is clearly a major contributor to this effect, but the masseter also has a part to play. The benefit of the IOZM is that it adds force without substantially contributing to strain or deformation of the skull. This may help explain why the

    Full Text Available Rhabdoviridae represent a diverse group of viruses with the potential to cause disease in humans, animals and plants. Currently there are nine genera in the family; however a large number of rhabdoviruses remain unassigned. Here we characterise three novel rhabdoviruses genomes. Almpiwar virus (ALMV, isolated from skinks in northern Queensland, is the first completely sequenced rhabdovirus from squamates, with serological studies indicating multiple animal host species. Harrison Dam virus (HARDV and Walkabout Creek virus (WACV were isolated from mosquitoes in the Northern Territory and biting midges in southern Queensland respectively and their vertebrate hosts remain unknown. Serological cross-neutralisation tests with other Australian rhabdoviruses indicate that ALMV, WACV and HARDV are distinct viruses with little antigenic cross-reactivity. Next-generation sequencing revealed that all viruses encode the core proteins common to rhabdoviruses (N, P, M, G and L, plus additional ORFs between the M and G genes. HARDV also contains a small ORF between the G and L genes. Phylogenetic analysis of N and L proteins suggests that HARDV and WACV share a common lineage with the tupaviruses and Sandjimba group, whereas ALMV is a distinct and divergent virus showing no clear relationship to any rhabdovirus except the recently characterised Niahka virus (NIAV.

    A novel experimental setup was designed to fabricate tungsten tips for scanning tunneling microscope (STM), based on simple mechanical lever principle. The equipment can quickly separate the tip from electrolyte to avoid the further etching of the fine-shaped tungsten tip. The setup is advantageous for its simplicity over complex electronic control systems. The use result in scanning electron microscope demonstrates that the radius of the tip can reach 50 nm. The tip was applied to scan the surface of highly-oriented pyrolytic graphite, and the results were satisfactory. It is shown that the tip can be used for the scanning of atomically resolved images.

    For the ‘front-line’ purchasing agent, it is obvious that not all categories of products and supplier relationships should be managed in the same way. Rather, in a modern category management approach, firms group similar products into ‘sourcing categories’ forming coherent supply markets (e.g., ‘metal sheets’, ‘leather’, ‘displays’, ‘cables’, etc.). Thus, to achieve cost reduction targets, a tailored mix of tactical sourcing levers for each sourcing category may be required. The fundamental q...

    2001-01-01

    In the 1920s, just after the War, an idea began taking root in the Old Continent, to build what could be described as the United States of Europe. Thirty years later, in 1951, a new source of energy, coal, paved the way for the economic integration of Europe. It culminated into monetary integration in January 2002. Economic integration makes sense in the context of the relatively small size of some national economies and markets, and the judicious utilization of rare resources and their unequal distribution. In this document, the author elaborated on the principles at play in economic integration and argued that the integration of the national energy markets could be the lever for economic integration through the gradual elimination of the various obstacles to trade. The author first presented a brief historical overview of economic integration from the perspective of global economic relationships, covering the period between the two world wars to the General Agreement on Tariffs and Trade (GATT) to the World Trade Organization (WTO). The concept and the forms of economic integration were reviewed. Energy integration as a lever of regional economic integration and as a factor in global economic insertion were discussed. Energy integration is a tool for the improvement of the human condition. 15 refs

  16. The Role of Control System in Increasing Corporate social Performance: The Use of Levers of Control

    2008-06-01

    Full Text Available One important instrument to be used in the control system design is strategic behaviors that can lead to the expected organization performance.  Referring to the extended definition of strategic behavior using stakeholder-based strategic behavior, corporate social performance is kind of strategic behavior to be influenced by using control system. This paper discusses how control system, using Simons‟ levers of control can play important role in increasing the corporate social performance. The interaction between control system, including belief system, boundary system, diagnostic control system, and interactive control system, as well as the corporate financial performance (CFP can affect the corporate social performance (CSP due to fact that increase in CFP resulting from the appropriate use of control system components enables the company has more chance to do the CSP. The levers of control are deemed to form an integral part of employee socialization and support the development of an organization‟s culture, the system of shared beliefs, values, norms, and mores of organizational members which are deemed to be a primary determinant of the direction of employee behavior.

    2006-12-01

    Full Text Available This paper describes the implementation of an e-learning strategy at a single higher education institution in terms of the levers used to promote effective uptake and ensure sustainable embedding. The focus of this work was at the level of the academic school using a range of change practices including the appointment of school-based learning technologists and e-learning champions, supporting schools to write their own strategies, a pedagogical framework of engaging with e-learning, and curriculum development and evaluation of school-supported projects. It is clear that the implementation of the e-learning strategy has led to a large and increasing proportion of our students experiencing blended learning. In addition, there are initial indications that this has enhanced some learning and teaching processes. Where there has been sustainable embedding of effective e-learning, the following levers were identified as particularly important: flexibility in practices that allow schools to contextualise their plans for change, the facilitation of communities of key staff and creating opportunities for staff to voice and challenge their beliefs about e-learning.

  18. A Lever Coupling Mechanism in Dual-Mass Micro-Gyroscopes for Improving the Shock Resistance along the Driving Direction

    Directory of Open Access Journals (Sweden)

    Yang Gao

    2017-04-01

    Full Text Available This paper presents the design and application of a lever coupling mechanism to improve the shock resistance of a dual-mass silicon micro-gyroscope with drive mode coupled along the driving direction without sacrificing the mechanical sensitivity. Firstly, the mechanical sensitivity and the shock response of the micro-gyroscope are theoretically analyzed. In the mechanical design, a novel lever coupling mechanism is proposed to change the modal order and to improve the frequency separation. The micro-gyroscope with the lever coupling mechanism optimizes the drive mode order, increasing the in-phase mode frequency to be much larger than the anti-phase one. Shock analysis results show that the micro-gyroscope structure with the designed lever coupling mechanism can notably reduce the magnitudes of the shock response and cut down the stress produced in the shock process compared with the traditional elastic coupled one. Simulations reveal that the shock resistance along the drive direction is greatly increased. Consequently, the lever coupling mechanism can change the gyroscope’s modal order and improve the frequency separation by structurally offering a higher stiffness difference ratio. The shock resistance along the driving direction is tremendously enhanced without loss of the mechanical sensitivity.

    'Is in fuel poverty a person who feels in his particular housing difficulties have the necessary energy supply to the satisfaction of basic needs due to the inadequacy of resources or its habitat conditions'. The rising cost of energy commodities in the late 2000's, added to the poor thermal quality an important part of French homes, has led to the emergence of fuel poverty in the public debate. Legislative recognition of these situations with the law 'Grenelle II' (from which is extracted the definition above) marked a decisive step in the fight against this complex problem. Affecting nearly 5 million households in France, fuel poverty is a major challenge for societies wishing to successfully achieve their energy transition. In this new publication, ENEA reports on the main levers of the fight against fuel poverty, the obstacles encountered and the needs for new solutions

    2003-05-01

    Two experiments were designed to evaluate whether brief access to a saccharin-ethanol solution would function as an effective unconditioned stimulus (US) in Pavlovian-autoshaping procedures. In these experiments, the insertion of a lever conditioned stimulus (CS) was followed by the brief presentation of a sipper tube containing saccharin-ethanol US solution. Experience with this Pavlovian-autoshaping procedure engendered lever CS-directed autoshaping conditioned responses (CRs) in all rats. In Experiment 1, the concentration of ethanol [0%, 2%, 4%, 6%, or 8% (vol./vol.)] in 0.1% saccharin was systematically increased within subjects across autoshaping sessions to evaluate the relation between a rat's drinking and lever pressing. In Experiment 2, the mean intertrial interval (ITI) duration (60, 90, 120 s) was systematically increased within subjects across autoshaping sessions to evaluate the effect of ITI duration on drinking and lever pressing. A pseudoconditioning control group received lever CS randomly with respect to the saccharin-ethanol US solution. In Experiment 1, lever-press autoshaping CRs developed in all rats, and the tendency of a rat to drink an ethanol concentration was predictive of the performance of lever-press autoshaping CRs. In Experiment 2, longer ITIs induced more lever CS-directed responding, and CS-US paired procedures yielded more lever CS-directed responding than that observed in CS-US random procedures. Saccharin-ethanol is an effective US in Pavlovian-autoshaping procedures, inducing more CS-directed responding than in pseudoconditioning controls receiving CS-US random procedures. More lever CS-directed responding was observed when there was more drinking of the saccharin-ethanol US solution (Experiment 1); when the CS and US were paired, rather than random (Experiment 2); and with longer mean ITI durations (Experiment 2). This pattern of results is consistent with the hypothesis that lever CS-directed responding reflects performance

    Some outbreaks associated with contaminated duodenoscopes have been attributed to biofilm formation. The objective of this study was to determine whether bacteria within an organic matrix could survive if the elevator lever was improperly positioned in the automated endoscope reprocessor (AER) after 1 round of reprocessing. Duodenoscope lever cavities with an open or sealed elevator wire channel were inoculated with 6-7 Log 10 of both Escherichia coli and Enterococcus faecalis in ATS2015 (Healthmark Industries, Fraser, MI) and dried for 2 hours. The duodenoscopes with the lever in the horizontal position were processed through 2 makes of AERs. The cavity was sampled using a flush-brush-flush method to determine the quantity of surviving bacteria. E faecalis (range, 21-6 Log 10 CFU) and E coli (range, 0-3 Log 10 CFU) survived disinfection of sealed or unsealed elevator wire channel duodenoscopes in 2 different AERs with and without cleaning cycles. If bacteria in organic residue are under the improperly positioned lever, then just 1 round of use is sufficient for bacteria to survive both liquid chemical sterilization and liquid chemical HLD regardless of whether or not the AER had a cleaning cycle.

  4. Rotational foot placement specifies the lever arm of the ground reaction force during the push-off phase of walking initiation.

    Erdemir, Ahmet; Piazza, Stephen J

    2002-06-01

    The lever arm of the ground reaction force (GRF) about the talocrural joint axis is a functionally important indicator of the nature of foot loading. Walking initiation experiments (ten subjects; age, 23-29 years) were completed to demonstrate that rotational foot placement is a possible strategy to specify the lever arm. Externally-rotated foot placement resulted in larger lever arms during push-off. A computer simulation of push-off revealed that a decreased lever arm reduces the plantarflexion moment necessary to maintain a constant forward velocity, while increasing the required plantarflexion velocity. Shortening of the foot thus diminishes the muscular force demand but also requires high muscle fiber shortening velocities that may limit the force generating capacity of plantar flexors. Decreased plantar flexion moment and slow walking previously noted in partial-foot amputees may result from shortened lever arms in this manner.

  5. Reliable quantification of bite-force performance requires use of appropriate biting substrate and standardization of bite out-lever.

    2014-12-15

    Bite-force performance is an ecologically important measure of whole-organism performance that shapes dietary breadth and feeding strategies and, in some taxa, determines reproductive success. It also is a metric that is crucial to testing and evaluating biomechanical models. We reviewed nearly 100 published studies of a range of taxa that incorporate direct in vivo measurements of bite force. Problematically, methods of data collection and processing vary considerably among studies. In particular, there is little consensus on the appropriate substrate to use on the biting surface of force transducers. In addition, the bite out-lever, defined as the distance from the fulcrum (i.e. jaw joint) to the position along the jawline at which the jaws engage the transducer, is rarely taken into account. We examined the effect of bite substrate and bite out-lever on bite-force estimates in a diverse sample of lizards. Results indicate that both variables have a significant impact on the accuracy of measurements. Maximum bite force is significantly greater using leather as the biting substrate compared with a metal substrate. Less-forceful bites on metal are likely due to inhibitory feedback from mechanoreceptors that prevent damage to the feeding apparatus. Standardization of bite out-lever affected which trial produced maximum performance for a given individual. Indeed, maximum bite force is usually underestimated without standardization because it is expected to be greatest at the minimum out-lever (i.e. back of the jaws), which in studies is rarely targeted with success. We assert that future studies should use a pliable substrate, such as leather, and use appropriate standardization for bite out-lever. © 2014. Published by The Company of Biologists Ltd.

    Research highlights: → We succeeded in recording structural changes of hydrated myosin cross-bridges. → We succeeded in position-marking the cross-bridges with site-directed antibodies. → We recorded cross-bridge movement at different regions in individual cross-bridge. → The movement was smallest at the cross-bridge-subfragment two boundary. → The results provide evidence for the cross-bridge lever arm mechanism. -- Abstract: Muscle contraction results from an attachment-detachment cycle between the myosin heads extending from myosin filaments and the sites on actin filaments. The myosin head first attaches to actin together with the products of ATP hydrolysis, performs a power stroke associated with release of hydrolysis products, and detaches from actin upon binding with new ATP. The detached myosin head then hydrolyses ATP, and performs a recovery stroke to restore its initial position. The strokes have been suggested to result from rotation of the lever arm domain around the converter domain, while the catalytic domain remains rigid. To ascertain the validity of the lever arm hypothesis in muscle, we recorded ATP-induced movement at different regions within individual myosin heads in hydrated myosin filaments, using the gas environmental chamber attached to the electron microscope. The myosin head were position-marked with gold particles using three different site-directed antibodies. The amplitude of ATP-induced movement at the actin binding site in the catalytic domain was similar to that at the boundary between the catalytic and converter domains, but was definitely larger than that at the regulatory light chain in the lever arm domain. These results are consistent with the myosin head lever arm mechanism in muscle contraction if some assumptions are made.

    Certain Pavlovian conditioned stimuli (CSs) paired with food unconditioned stimuli (USs) come to elicit approach and even consumption-like behaviors in rats (sign-tracking). We investigated the effects of lesions of the nucleus accumbens core (ACbC) or shell (ACbS) on the acquisition of sign-tracking in a discriminative autoshaping procedure in which presentation of one lever CS was followed by delivery of sucrose, and another was not. Although we previously found that bilateral lesions of the whole ACb disrupted the initial acquisition of sign-tracking, neither ACbC or ACbS lesions affected the rate or percentage of trials in which rats pressed the CS+. In addition, detailed video analysis showed no effect of either lesion on the topography of the sign-tracking conditioned response (CR). These and other results from lesion studies of autoshaping contrast with those from previous sign-tracking experiments that used purely visual cues (Parkinson et al., 2000a,b), suggesting that the neural circuitry involved in assigning incentive value depends upon the nature of the CS.

    Drug discrimination studies have suggested that the subjective effects of low doses of (±)3,4-methylenedioxymethamphetamine (MDMA) are readily differentiated from those of d-amphetamine (AMPH) and that the discriminative stimulus properties are mediated by serotonergic and dopaminergic mechanisms, respectively. Previous studies, however, have primarily examined responses to doses that do not produce substantial increases in extracellular dopamine. The present study determined whether doses of MDMA that produce increases in synaptic dopamine would also produce subjective effects that were more like AMPH and were sensitive to pharmacological manipulation of D1-like receptors. A three-lever drug discrimination paradigm was used. Rats were trained to respond on different levers following saline, AMPH (0.5mg/kg, IP) or MDMA (1.5mg/kg, IP) injections. Generalization curves were generated for a range of different doses of both drugs and the effect of the D1-like antagonist, SCH23390 on the discriminative stimulus effects of different doses of MDMA was determined. Rats accurately discriminated MDMA, AMPH and saline. Low doses of MDMA produced almost exclusive responding on the MDMA lever but at doses of 3.0mg/kg MDMA or higher, responding shifted to the AMPH lever. The AMPH response produced by higher doses of MDMA was attenuated by pretreatment with SCH23390. The data suggest that low doses and higher doses of MDMA produce distinct discriminative stimuli. The shift to AMPH-like responding following administration of higher doses of MDMA, and the decrease in this response following administration of SCH23390 suggests a dopaminergic component to the subjective experience of MDMA at higher doses.

    Full Text Available IntroductionSimulated-use buildup biofilm (BBF model was used to assess various extraction fluids and friction methods to determine the optimal sample collection method for polytetrafluorethylene channels. In addition, simulated-use testing was performed for the channel and lever cavity of duodenoscopes.Materials and methodsBBF was formed in polytetrafluorethylene channels using Enterococcus faecalis, Escherichia coli, and Pseudomonas aeruginosa. Sterile reverse osmosis (RO water, and phosphate-buffered saline with and without Tween80 as well as two neutralizing broths (Letheen and Dey–Engley were each assessed with and without friction. Neutralizer was added immediately after sample collection and samples concentrated using centrifugation. Simulated-use testing was done using TJF-Q180V and JF-140F Olympus duodenoscopes.ResultsDespite variability in the bacterial CFU in the BBF model, none of the extraction fluids tested were significantly better than RO. Borescope examination showed far less residual material when friction was part of the extraction protocol. The RO for flush-brush-flush (FBF extraction provided significantly better recovery of E. coli (p = 0.02 from duodenoscope lever cavities compared to the CDC flush method.Discussion and conclusionWe recommend RO with friction for FBF extraction of the channel and lever cavity of duodenoscopes. Neutralizer and sample concentration optimize recovery of viable bacteria on culture.

  12. Hybrid Kalman and unscented Kalman filters for INS/GPS integrated system considering constant lever arm effect

    2015-01-01

    In inertial navigation system (INS) and global positioning system (GPS) integrated system, GPS antennas are usually not located at the same location as the inertial measurement unit (IMU) of the INS, so the lever arm effect exists, which makes the observation equation highly nonlinear. The INS/GPS integration with constant lever arm effect is studied. The position relation of IMU and GPS’s antenna is represented in the earth centered earth fixed frame, while the velocity relation of these two systems is represented in local horizontal frame. Due to the small integration time interval of INS, i.e. 0.1 s in this work, the nonlinearity in the INS error equation is trivial, so the linear INS error model is constructed and addressed by Kalman filter’s prediction step. On the other hand, the high nonlinearity in the observation equation due to lever arm effect is addressed by unscented Kalman filter’s update step to attain higher accuracy and better applicability. Simulation is designed and the performance of the hybrid filter is validated.

    Calibration of the optical lever sensitivities of atomic force microscope (AFM) cantilevers is especially important for determining the force in AFM measurements. These sensitivities depend critically on the cantilever mode used and are known to differ for static and dynamic measurements. Here, we calculate the ratio of the dynamic and static sensitivities for several common AFM cantilevers, whose shapes vary considerably, and experimentally verify these results. The dynamic-to-static optical lever sensitivity ratio is found to range from 1.09 to 1.41 for the cantilevers studied - in stark contrast to the constant value of 1.09 used widely in current calibration studies. This analysis shows that accuracy of the thermal noise method for the static spring constant is strongly dependent on cantilever geometry - neglect of these dynamic-to-static factors can induce errors exceeding 100%. We also discuss a simple experimental approach to non-invasively and simultaneously determine the dynamic and static spring constants and optical lever sensitivities of cantilevers of arbitrary shape, which is applicable to all AFM platforms that have the thermal noise method for spring constant calibration.

  15. Levers for Language Growth: Characteristics and Predictors of Language Trajectories between 4 and 7 Years.

    Full Text Available Evidence is required as to when and where to focus resources to achieve the greatest gains for children's language development. Key to these decisions is the understanding of individual differences in children's language trajectories and the predictors of those differences. To determine optimal timing we must understand if and when children's relative language abilities become fixed. To determine where to focus effort we must identify mutable factors, that is those with the potential to be changed through interventions, which are associated with significant differences in children's language scores and rate of progress.Uniquely this study examined individual differences in language growth trajectories in a population sample of children between 4 and 7 years using the multilevel model for change. The influence of predictors, grouped with respect to their mutability and their proximity to the child (least-mutable, mutable-distal, mutable-proximal, were estimated.A significant degree of variability in rate of progress between 4 and 7 years was evident, much of which was systematically associated with mutable-proximal factors, that is, those factors with evidence that they are modifiable through interventions with the child or family, such as shared book reading, TV viewing and number of books in the home. Mutable-distal factors, such as family income, family literacy and neighbourhood disadvantage, hypothesised to be modifiable through social policy, were important predictors of language abilities at 4 years.Potential levers for language interventions lie in the child's home learning environment from birth to age 4. However, the role of a family's material and cultural capital must not be ignored, nor should the potential for growth into the school years. Early Years services should acknowledge the effects of multiple, cascading and cumulative risks and seek to promote child language development through the aggregation of marginal gains in the pre

    Full Text Available Calculation of kinematic mechanisms is very time-consuming work. Due to the content of a large number of similar operations can be automated using computers. Forthis purpose, it is necessary to implement a software implementation ofthe mathematical model of calculation of kinematic mechanisms of the second class. In the article on Turbo Pascal presents the text module to library procedures all kinematic studies of planar lever mechanisms of the second class. The determination of the kinematic characteristics of the mechanism and the construction of its provisions, plans, plans, speeds and accelerations carried out on the example of the six-link mechanism. The beginning of the motionless coordinate system coincides with the axis of rotation of the crank AB. It is assumed that the known length of all links, the positions of all additional points of links and the coordinates of all kinematic pairs rack mechanism, i.e. this stage of work to determine the kinematics of the mechanism must be preceded by a stage of synthesis of mechanism (determining missing dimensions of links. Denote the coordinates of point C and considering that the analogues of velocities and accelerations of this point is 0 (stationary point, appeal to the procedure that computes the kinematics group the Assyrians (GA third. Specify kinematic parameters of point D, taking the beginning of the guide slide E at point C, the angle, the analogue of the angular velocity and the analogue of the angular acceleration of the guide is zero, knowing the length of the connecting rod DE and the length of link 5, refer to the procedure for the GA of the second kind. The use of library routines module of the kinematic calculation, makes it relatively simple to organize a simulation of the mechanism motion, to calculate the projection analogues of velocities and accelerations of all links of the mechanism, to build plans of the velocities and accelerations at each position of the mechanism.

  17. Modified compensation algorithm of lever-arm effect and flexural deformation for polar shipborne transfer alignment based on improved adaptive Kalman filter

    2017-01-01

    Due to the lever-arm effect and flexural deformation in the practical application of transfer alignment (TA), the TA performance is decreased. The existing polar TA algorithm only compensates a fixed lever-arm without considering the dynamic lever-arm caused by flexural deformation; traditional non-polar TA algorithms also have some limitations. Thus, the performance of existing compensation algorithms is unsatisfactory. In this paper, a modified compensation algorithm of the lever-arm effect and flexural deformation is proposed to promote the accuracy and speed of the polar TA. On the basis of a dynamic lever-arm model and a noise compensation method for flexural deformation, polar TA equations are derived in grid frames. Based on the velocity-plus-attitude matching method, the filter models of polar TA are designed. An adaptive Kalman filter (AKF) is improved to promote the robustness and accuracy of the system, and then applied to the estimation of the misalignment angles. Simulation and experiment results have demonstrated that the modified compensation algorithm based on the improved AKF for polar TA can effectively compensate the lever-arm effect and flexural deformation, and then improve the accuracy and speed of TA in the polar region.

    2010-01-01

    This paper describes the design and testing of an indirect hanging pendulum thrust balance using a laser-optical-lever principle to provide micro- to millinewton thrust measurement for the development of electric propulsion systems. The design philosophy allows the selection of the total thrust range in order to maximize resolution through a counterbalanced pendulum principle, as well as passive magnetic damping in order to allow relatively rapid transient thrust measurement. The balance was designed for the purpose of hollow cathode microthruster characterization, but could be applied to other electric propulsion devices in the thrust range of micro- to millinewtons. An initial thrust characterization of the T5 hollow cathode is presented

    Over recent years, therapeutic patient education has become part of dental medicine. Management of early childhood caries, known to be a very common chronic disease, has evolved to include an educational dimension. The objective of this study was to identify the levers and barriers to the development of formalized therapeutic education programmes and alternatives. A comprehensive exploratory qualitative study was conducted between November 2015 and June 2016 on a targeted sample of 15 people aware of the problem of TPE in dentistry. The study showed that TPE training in dentistry is underdeveloped, despite its numerous benefits: change of the healthcare professional's approach, implementation of structured educational programmes, development of research, etc. There are many obstacles to the development of TPE programmes: insufficient resources, rigid legislation or lack of knowledge of TPE practices. The dental profession is an obstacle itself because of its lack of understanding and variable degrees of integration the medical community. There are multiple levers, but the main ones are changing attitudes of the profession and the provision of resources to develop TPE. Although alternatives to TPE programmes exist (accompanying measures, short educational strategies, connected health), they cannot replace TPE. More educational strategies must be developed in the field of dentistry. However, the framework of TPE must be adapted to the profession to ensure good uptake.

    Previous studies have suggested that the two-handled (levered) shovel is advantageous over the conventional spade from a biomechanical point of view. The aim of this experiment was to determine whether less energy was consumed while shovelling a load of sand with this shovel compared to a conventional tool. Accordingly, an experiment was designed in which subjects (n = 10) shovelled 1815 kg sand under laboratory conditions using either a conventional or a levered shovel. Heart rate and oxygen consumption were measured continuously during the trial and subjective data on perceived exertion, general fatigue and body discomfort were recorded after the trial. Although total energy expenditure was similar under both conditions (120 +/- 20 and 125 +/- 25 kcal; conventional versus two-handled spade), average heart rate was 4% higher when the two-handled shovel was used (p shovel (p shovel 1815 kg sand with the conventional shovel and the two-handled tool despite lower mass of sand per scoop with the latter. This can be explained by the fact that the increased mass of the additional handle compensated for the lower mass of sand per scoop. The higher average heart rate while shovelling with the two-handled shovel can be explained by the more erect posture.

    Unlike sagittal plane prosthesis alignment, few studies have observed the effects of transverse plane alignment on gait and prosthesis behaviour. Changes in transverse plane rotation angle will rotate the points of loading on the prosthesis during stance and may alter its mechanical behaviour. This study observed the effects of increasing the external transverse plane rotation angle, or toe-out, on foot compression and effective lever arm of three commonly prescribed prosthetic feet. The roll-over shape of a SACH, Flex and single-axis foot was measured at four external rotation angle conditions (0°, 5°, 7° and 12° relative to neutral). Differences in foot compression between conditions were measured as average distance between roll-over shapes. Increasing the transverse plane rotation angle did not affect foot compression. However, it did affect the effective lever arm, which was maximized with the 5° condition, although differences between conditions were small. Increasing the transverse plane rotation angle of prosthetic feet by up to 12° beyond neutral has minimal effects on their mechanical behaviour in the plane of walking progression during weight-bearing.

    On April 14, 1985, the Westinghouse Nuclear Services Integration Division (NSID) issued Technical Bulletin No. NSID-TB-85-17 advising their customers of a potential malfunction in Westinghouse Type DS Class 1E circuit breakers because of broken spring release latch levers. These electrically operated type DS breakers will not close electrically when the spring release latch lever has been broken off. Twenty-five broken levers have been reported and evaluated. This evaluation shows concentrations of incidents traceable to manufacturing in the following periods of time: early 1975, April 1976, and early 1978. This circuit breaker failure, as discussed, adversely affects the safety function (closing on demand) when the circuit breaker is used in the Engineered Safety Features Systems. However, this failure mode will not affect the safety trip function when it is used in the reactor protection system

    Care integration has been the focus of recent health system reforms. Given their functions at all levels of the care continuum, nurses have a substantial and primordial role to play in such integration processes. The aim of this study was to identify levers and strategies that organizations can use to support the development of a nursing practice aligned with the requirements of care integration in a health and social services centre (HSSC) in Quebec. The research design was a cross-sectional descriptive qualitative study based on a single case study with nested levels of analysis. The case was a public, multi-disciplinary HSSC in a semi-urban region of Quebec. Semi-structured interviews with 37 persons (nurses, professionals, managers, administrators) allowed for data saturation and ensured theoretical representation by covering four care pathways constituting different care integration contexts. Analysis involved four steps: preparing a predetermined list of codes based on the reference framework developed by Minkman (2011); coding transcript content; developing general and summary matrices to group observations for each care pathway; and creating a general model showing the overall results for the four pathways. The organization's capacity for response with regard to developing an integrated system of services resulted in two types of complementary interventions. The first involved investing in key resources and renewing organizational structures; the second involved deploying a series of organizational and clinical-administrative processes. In resource terms, integration efforts resulted in setting up new strategic services, re-arranging physical infrastructures, and deploying new technological resources. Organizational and clinical-administrative processes to promote integration involved renewing governance, improving the flow of care pathways, fostering continuous quality improvement, developing new roles, promoting clinician collaboration, and strengthening

  5. Effects of psychotropic agents on extinction of lever-press avoidance in a rat model of anxiety vulnerability

    Full Text Available Avoidance and its perseveration represent key features of anxiety disorders. Both pharmacological and behavioral approaches (i.e. anxiolytics and extinction therapy have been utilized to modulate avoidance behavior in patients. However, the outcome has not always been desirable. Part of the reason is attributed to the diverse neuropathology of anxiety disorders. Here, we investigated the effect of psychotropic drugs that target various monoamine systems on extinction of avoidance behavior using lever-press avoidance task. Here we used the Wistar-Kyoto (WKY rat, a unique rat model that exhibits facilitated avoidance and extinction resistance along with malfunction of the dopamine (DA system. Sprague Dawley (SD and WKY rats were trained to acquire lever-press avoidance. WKY rats acquired avoidance faster and to a higher level compared to SD rats. During pharmacological treatment, bupropion, and desipramine significantly reduced avoidance response selectively in WKY rats. However, after the discontinuation of drug treatment, only those WKY rats that were previously treated with desipramine exhibited lower avoidance response compared to the control group. In contrast, none of the psychotropic drugs facilitated avoidance extinction in SD rats. Instead, desipramine impaired avoidance extinction and increased non-reinforced response in SD rats. Interestingly, paroxetine, a widely used antidepressant and anxiolytic, exhibited the weakest effect in WKY rats and no effects at all in SD rats. Thus, our data suggest that malfunctions in brain catecholamine system could be one of the underlying etiologies of anxiety-like behavior, particularly avoidance perseveration. Pharmacological manipulation targeting DA and norepinephrine is more effective to facilitate extinction learning in this strain. The data from the present study may shed light on new pharmacological approaches to treat patients with anxiety disorders who are not responding to serotonin re

    Pavlovian autoshaping CRs are directed and reflexive consummatory responses targeted at objects repeatedly paired with rewarding substances. To evaluate the hypothesis that autoshaping may provide an animal learning model of vulnerability to drug abuse, this study relates individual differences in lever-press autoshaping CR performance in rats to stress-induced corticosterone release and tissue monoamine levels in the mesolimbic dopamine tract. Long-Evans rats (n = 14) were given 20 sessions of Pavlovian autoshaping training wherein the insertion of a retractable lever CS was followed by the response-independent presentation of food US. Large between-subjects differences in lever-press autoshaping CR performance were observed, with group high CR frequency (n = 5) performing many more lever press CRs than group low CR frequency (n = 9). Tail-blood samples were obtained before and after the 20th autoshaping session, then 24 h later the rats were sacrificed and dissection yielded tissue samples of nucleus accumbens (NAC), prefrontal cortex (PFC), caudate putamen (CP), and ventral tegmental area (VTA). Serum levels of postsession corticosterone were elevated in group high CR frequency. HPLC revealed that group high CR frequency had higher tissue levels of dopamine and DOPAC in NAC, lower levels of DOPAC/DA turnover in CP, and lower levels of 5-HIAA and lower 5-HIAA/5-HT turnover in VTA. The neurochemical profile of rats that perform more autoshaping CRs share some features of vulnerability to drug abuse.

    Previous studies have shown that large increases in food intake in nondeprived animals can be induced by injections of both the GABA(A) agonist muscimol and the μ-opioid agonist DAMGO into the nucleus accumbens shell (AcbSh), while injections of the catecholamine agonist amphetamine have little effect. In the current study we examined whether injections of these drugs are able to increase food-reinforced lever pressing in nondeprived rats. Twelve subjects were trained to lever press on a continuous reinforcement schedule while food deprived and were then tested after being placed back on ad libitum feeding. Under these conditions, responding was markedly increased by injections of either muscimol or DAMGO, although the onset of the effects of the latter drug was delayed by 30-40 min. In contrast, amphetamine injections failed to increase reinforced lever pressing, although they did enhance responding on a non-reinforced lever, presumably reflecting alterations in behavioral activation. These results demonstrate that stimulation of GABA(A) and μ-opioid receptors within the AcbSh is able to promote not only food intake, but also food-directed operant behavior. In contrast, stimulation of AcbSh dopamine receptors may enhance behavioral arousal, but does not appear to specifically potentiate behaviors directed toward food procurement.

    Full Text Available School closures, while an effective measure against the spread of disease during a pandemic, may carry unintended social and economic consequences for students and families. We evaluated these costs and consequences following a 4-day school closure in Mississippi's Harrison County School District (HCSD.In a survey of all households with students enrolled in HCSD, we collected information on difficulties related to the school closure, including interruption of employment and pay, loss of access to subsidized school meals, and arrangement of alternative childcare. We analyzed this information in the context of certain demographic characteristics of the survey respondents and households, such as race, level of education, and income. We also estimated the average number of lost work days and documented the childcare alternatives chosen by households affected by the school closure.We received 2,229 (28.4% completed surveys from an estimated 7,851 households eligible to participate. About half (1,082 [48.5%] of the households experienced at least some difficulty during the closure, primarily in three areas: uncertainty about duration of the closure, lost income, and the effort of arranging alternate childcare. Adults working outside the home, particularly the major wage earner in the household, were more likely to suffer lost income while schools were closed, an effect mitigated by paid leave benefits. Difficulty arranging childcare was reported most frequently by respondents with lower levels of education and households with younger children. Beyond the top three concerns expressed by households in HCSD, the survey also shed light on the issue of food insecurity when subsidized school meals are not available. Reported by 17.9% of households participating in the subsidized school lunch program, difficulty providing meals during the closure was associated with higher numbers of dependent children, selection of "other" as the race of the household

    Parrotfishes (family Labridae: Scarini) are regarded to have important roles for maintaining the ecosystem balance in coral reefs due to their removal of organic matter and calcic substrates by grazing. The purpose of the present study was to clarify the interspecific differences in grazing ability of five parrotfish species (Chlorurus sordidus, C. bowersi, Scarus rivulatus, S. niger and S. forsteni) in relation to interspecific differences in jaw-lever mechanics and the relative weight of the adductor mandibulae (muscles operating jaw closing). The grazing ability was calculated by using stomach contents (CaCO3 weight/organic matter weight) defined as the grazing ability index (GAI). There were significant interspecific differences in GAI (C. sordidus = C. bowersi > S. rivulatus > S. niger = S. forsteni). Teeth of C. sordidus and C. bowersi were protrusive-shape whereas teeth of S. rivulatus, S. niger and S. forsteni were flat-shape. C. sordidus and C. bowersihave jaw-lever mechanics producing a greater biting force and have a larger weight of adductor mandibulae. S. rivulatus has jaw-lever mechanics producing a greater biting force but a smaller weight of adductor mandibulae that produce an intermediate biting force. In contrast, S. niger and S. forsteni have jaw-lever mechanics producing a lesser biting force and have a smaller weight of adductor mandibulae. Feeding rates and foray size of S. rivulatus, S. niger and S. forsteni were greater than C. sordidus and C. bowersi. The degree in bioerosion (GAI × feeding rate) was the largest for S. rivulatusand the smallest for S. forsteni. The degree in bioerosion for C. sordidus was larger than S. niger whereas relatively equal between C. bowersi and S. niger. These results suggest that interspecific difference in GAI was explained by interspecific differences in teeth shape, jaw-lever mechanics and relative weight of adductor mandibulae. The interspecific difference in the degree of bioerosion suggests the

    The key question in understanding how force and movement are produced in muscle concerns the nature of the cyclic interaction of myosin molecules with actin filaments. The lever arm of the globular head of each myosin molecule is thought in some way to swing axially on the actin-attached motor domain, thus propelling the actin filament past the myosin filament. Recent X-ray diffraction studies of vertebrate muscle, especially those involving the analysis of interference effects between myosin head arrays in the two halves of the thick filaments, have been claimed to prove that the lever arm moves at the same time as the sliding of actin and myosin filaments in response to muscle length or force steps. It was suggested that the sliding of myosin and actin filaments, the level of force produced and the lever arm angle are all directly coupled and that other models of lever arm movement will not fit the X-ray data. Here, we show that, in addition to interference across the A-band, which must be occurring, the observed meridional M3 and M6 X-ray intensity changes can all be explained very well by the changing diffraction effects during filament sliding caused by heads stereospecifically attached to actin moving axially relative to a population of detached or non-stereospecifically attached heads that remain fixed in position relative to the myosin filament backbone. Crucially, and contrary to previous interpretations, the X-ray interference results provide little direct information about the position of the myosin head lever arm; they are, in fact, reporting relative motor domain movements. The implications of the new interpretation are briefly assessed.

    Ten male Sprague-Dawley rats received 6-hydroxydopamine-induced lesions of the dorsal noradrenergic bundle and 10 others underwent control operations. The lesion depleted levels of noradrenaline in the hippocampus to 2% of those in the controls. All rats were then trained for 16 sessions to lever-press in a Skinner box on a variable interval 18 sec schedule of food-reinforcement, then for 42 days on a successive discrimination between periods of variable interval (VI 18 sec) food-reinforcement and periods of extinction. This report describes the effects of chlordiazepoxide (CDP; 5 mg/kg) and propranolol (5 and 10 mg/kg) injected intraperitoneally in both groups on modified ABBA designs after this training. Both drugs increased the response rates in extinction periods. The effect of propranolol was similar at each dose and smaller than that of CDP. Although CDP and propranolol (5 mg/kg) increased variable interval response rates also, this could not account for the effect on extinction response rates. Responding did not differ between the lesioned and control animals and the effects of drugs were similar in each group. It is unlikely that CDP or propranolol release nonrewarded responding by disrupting transmission in the dorsal noradrenergic bundle.

    2009-08-01

    Full Text Available This article deals with Harrison Birtwistle’s rewriting of the myth of Orpheus in his opera The Mask of Orpheus (1986. Written on a libretto by Peter Zinovieff, The Mask of Orpheus is part of a long tradition of operas dealing with the famous Greek myth. Yet, the way it is tackled by Birtwistle and Zinovieff is very different from what was done in the past. They do not present the spectator with the key elements of the story in a linear way but simultaneously. Different versions of the myth are introduced and sometimes we are presented with contradictory versions at the same time to force us to be active and aware of the existence of different kinds of dualities. The simultaneous presentation of some events is also connected to the way Birtwistle and Zinovieff play with the notion of time in their opera. One of their aims is to show how memory functions. When you remember something the frontier between past and present is blurred and the remembrance of things past is part of an endless cycle where things are perpetually brought to life, a very important aspect of myths whose universal and timeless nature is thus emphasized. Rituals, like myths, are based on the idea of repetition as well as on the idea of returning to the origins. This is why the opera may be considered as a ritualistic piece of work; this is underlined by the omnipresence of the figure three—a ritual number—in the literary and musical structure of The Mask of Orpheus.

    1993-01-01

    On July 1, 1992, Virginia Electric and Power Company (VEPCO), licensee for North Anna Power Station (North Anna), Units 1 and 2, reported to the NRC that over a three-month period in 1992, three K-M model NZM6-63, 480-Vac MCCBs had tripped without appreciable load or fault condition or other electrical or mechanical transient. The three failed MCCBs were located in the cable vault and tunnel area of North Anna-2 and supplied power to motor operated valves in the charging and safety injection systems. The switch handles were found in the trip-free position and the breakers could not be relatched and reclosed. Examination of the internals of one of the three failed breakers revealed that its support lever (also described by VEPCO as a ''spring arm''), located in the rear compartment of the case, had fractured. This caused the breaker to trip and to become incapable of being reclosed. The NRC has determined that the support levers only in K-M model NZM6, NZM6b, and NZMH6 MCCBs, rated for 100 amperes and below and manufactured from 1972 on, have been made of the same type of plastic used in the support levers of the MCCBs that failed at North Anna-2

    Introduction: Orthotopic liver transplantation (OLT) has become an accepted treatment for endstage liver disease. However, postoperative complications result in significant patient morbidity and mortality. Early detection and treatment of these complications is therefore of utmost importance. Materials and methods: We retrospectively reviewed the postoperative complications of the patients who underwent OLT at our institution. Duplex Doppler sonography and cholangiography were the primary imaging modalities in postoperative evaluation of the transplanted liver. Other important techniques were CT, MRI, and angiography, which may contribute to a reliable diagnosis of vascular or biliary complications. Results: Second to primary organ dysfunction, vascular complications are the most frequent cause of graft loss. Thrombosis of the hepatic artery is the most common and most serious vascular complication, with a reported incidence from 4 to 42%. Bile duct sludge, leaks and strictures are frequent complications after liver transplantation, which can contribute to graft dysfunction. Biliary tract complications usually occur within the first 3 months and require interventional radiological or surgical therapy. Since liver transplant recipients undergo immunosuppressive therapy, they are at increased risk of developing late post-transplant malignancies, which are best depicted by US, CT or MRI. However, radiological diagnosis of lymphoproliferative disorder has to be confirmed by liver biopsy. Conclusion: Cholangiography and Duplex sonography are routinely used in the postoperative evaluation of patients with OLT. CT, MRI, and angiography are problem-solving tools in equivocal cases.

    In a changing European market, GRTgaz company is in charge of the double mission of supplying natural gas to the end user in optimal cost and security conditions, and also of accompanying the opening of the gas market in France by making the necessary arrangements for a non-discriminatory access of the network to all granted suppliers. GRTgaz, daughter company of Gaz de France group and in charge of gas transport, has laid down the goal to develop its supply capacity thanks to an ambitious program of investment for the 10 years to come. Beside the advantage of allowing the end user to chose his gas supplier, these investments offer the opportunity of improving the safety of facilities and of reducing their environmental impact. This article presents an interview of J. Laurelut, general director of GRTgaz, who explains the 10 years development plan of his company. (J.S.)

    Skilled forelimb function in mice is traditionally studied through behavioral paradigms that require extensive training by investigators and are limited by the number of trials individual animals are able to perform within a supervised session. We developed a skilled lever positioning task that mice can perform within their home cage. The task requires mice to use their forelimb to precisely hold a lever mounted on a rotary encoder within a rewarded position to dispense a water reward. A Raspberry Pi microcomputer is used to record lever position during trials and to control task parameters, thus making this low-footprint apparatus ideal for use within animal housing facilities. Custom Python software automatically increments task difficulty by requiring a longer hold duration, or a more accurate hold position, to dispense a reward. The performance of individual animals within group-housed mice is tracked through radio-frequency identification implants, and data stored on the microcomputer may be accessed remotely through an active internet connection. Mice continuously engage in the task for over 2.5 mo and perform ~500 trials/24 h. Mice required ~15,000 trials to learn to hold the lever within a 10° range for 1.5 s and were able to further refine movement accuracy by limiting their error to a 5° range within each trial. These results demonstrate the feasibility of autonomously training group-housed mice on a forelimb motor task. This paradigm may be used in the future to assess functional recovery after injury or cortical reorganization induced by self-directed motor learning. NEW & NOTEWORTHY We developed a low-cost system for fully autonomous training of group-housed mice on a forelimb motor task. We demonstrate the feasibility of tracking both end-point, as well as kinematic performance of individual mice, with each performing thousands of trials over 2.5 mo. The task is run and controlled by a Raspberry Pi microcomputer, which allows for cages to be

    This is the final report of a research project (ABSTRACT-colurba) which aimed at exploring decision mechanisms and organisational dynamics underlying the elaboration of strategies of adaptation to climate changes by using results of a field study among ten previously selected French local communities. The objectives were to determine priority local social and economic challenges associated with expected impacts of climate changes, to identify economic, organisational and cognitive barriers and levers (at the State, representative or collectivity level) to an optimal implementation of measures of reduction of local vulnerabilities to climate changes, to identify possible or already used diagnosis tools for the assessment of costs and of priority investments, and to make comparisons with other referenced cases and to assess possibilities to bypass barriers thanks to a dialogue with stakeholders. After a presentation of the project (objectives, institutional context, guides and methodologies, scientific approach for data acquisition and analysis), the report presents and discusses the obtained results regarding the place given to adaptation in local policies (PCET, the French local climate-energy plans), representations of adaptation, the inclusion of adaptation in the agenda of public climatic action, tools to make adaptation operational, barriers and levers to action implementation

  7. Food quality and motivation: a refined low-fat diet induces obesity and impairs performance on a progressive ratio schedule of instrumental lever pressing in rats.

    Purified high-fat diet (HFD) feeding causes deleterious metabolic and cognitive effects when compared with unrefined low-fat diets in rodent models. These effects are often attributed to the diet's high content of fat, while less attention has been paid to other mechanisms associated with the diet's highly refined state. Although the effects of HFD feeding on cognition have been explored, little is known about the impact of refined vs. unrefined food on cognition. We tested the hypothesis that a refined low-fat diet (LFD) increases body weight and adversely affects cognition relative to an unrefined diet. Rats were allowed ad libitum access to unrefined rodent chow (CON, Lab Diets 5001) or a purified low-fat diet (REF, Research Diets D12450B) for 6 months, and body weight and performance on an instrumental lever pressing task were recorded. After six months on their respective diets, group REF gained significantly more weight than group CON. REF rats made significantly fewer lever presses and exhibited dramatically lower breaking points than CON rats for sucrose and water reinforcement, indicating a chronic reduction of motivation for instrumental performance. Switching the rats' diet for 9 days had no effect on these measures. Diet-induced obesity produces a substantial deficit in motivated behavior in rats, independent of dietary fat content. This holds implications for an association between obesity and motivation. Specifically, behavioral traits comorbid with obesity, such as depression and fatigue, may be effects of obesity rather than contributing causes. To the degree that refined foods contribute to obesity, as demonstrated in our study, they may play a significant contributing role to other behavioral and cognitive disorders.

    Taking the Tours conurbation as an example, this study examines how to elaborate and define a new territorial coherence scheme (a land and urban planning tool) which would include a planned reduction of greenhouse gas emissions by a factor 4 between 2020 and 2030. It is therefore a prospective study with 2006 as a reference year (reductions are assessed with respect to 2006 due to data availability). After an analysis of the reference situation (2006) and of objectives, the report presents the scenario for 2020-2030, analyses the various levers in different sectors (mobility, housing, office building, industry and construction, agriculture), and examines possibilities related to the production of renewable energy, the adaptation to climate change, the creation of a new governance to mitigate and to adapt to climate change. Expected gains are discussed for transports, housing, office building, industry, agriculture, renewable energies, and adaptation. The last part reports a sensitive approach to a post-carbon world through different workshops (with children or within a fiction writing workshop)

    A multiplexer technique is used to individually measure an array of 256 split gates on a single GaAs/AlGaAs heterostructure. This results in the generation of large volumes of data, which requires the development of automated data analysis routines. An algorithm is developed to find the spacing between discrete energy levels, which form due to transverse confinement from the split gate. The lever arm, which relates split gate voltage to energy, is also found from the measured data. This reduces the time spent on the analysis. Comparison with estimates obtained visually shows that the algorithm returns reliable results for subband spacing of split gates measured at 1.4 K. The routine is also used to assess direct current bias spectroscopy measurements at lower temperatures (50 mK). This technique is versatile and can be extended to other types of measurements. For example, it is used to extract the magnetic field at which Zeeman-split 1D subbands cross one another

    Full Text Available The issue of collaboration between science, industry and state is of relevance in domestic and international practice. In leading countries of the world and in Ukraine compatible production and scientific complexes are created; collaboration between research institutions and state is established, in particular the theory and practice of collaboration between science, industry and state on the basis of Triple Helix Model is widespread in the world; in scientific papers objects of research of economic processes, subjects of research of the economic theory are considered. However, there are no works where the objects and tasks of economic researches are studied on the basis of macroeconomic environment, and a distinct principle to distinguish research objects relating to different economies and types of production is laid out; scientific and practical problems of economy in the field of collaboration between state, science and industry are clearly defined. According to the purpose of the article (to specify scientific and practical tasks to rationalize scientific research, the experience gained is systematized and a scheme-matrix of scientific and practical problems is proposed. In scientific practice there are works highlighting principles of scientific research work, research tasks in the field of economy, scientific problems of economy but there are no works considering both principles and tasks of collaboration of academic economists with state and industry in order to provide scientists with recommendations on optimization of economic processes to improve the economic efficiency. Taking into account the experience gained, principles of collaboration of academic economists with the state and industry are identified. On the basis of the developed matrix of scientific and practical tasks, the principle of impact of political factors on managerial levers, the level of Gross Domestic Product and Gross Social Product is demonstrated.

  17. Carbon pricing. A lever for energy transition

    International Nuclear Information System (INIS)

    2016-01-01

    The international community has set itself the target of limiting the global temperature rise to 2 deg. C. In today's world, the challenge is to invent new ways of manufacturing goods, producing food, travelling and keeping ourselves warm, without emitting more greenhouse gases (GHG) into the atmosphere than what we are technically able to remove from it. Climate action can be considered as an insurance for our societies against unacceptable costs generated by the risk of increasingly frequent climate-triggered natural disasters, irreversible damage to ecosystems and mass population migrations. In addition to avoid climate damage there are many benefits of climate action, including greater energy autonomy, reduced atmospheric pollution, which is harmful for human health, and the economic benefits of new green growth sectors. However, the efforts needed to make the transition to economies that emit fewer greenhouse gases must not be underestimated. This transition requires the mass redirection of investments into clean transport, renewable energy sources, building insulation and the development of agro-ecology, in a highly restricted financial and budgetary context. The economic and financial tools used for explicit or implicit carbon pricing give clear messages about the benefits of emitting less carbon, or alternatively the cost of greenhouse gas emissions for society. Consequently, they make it possible to accelerate the energy transition. 74 countries and over 1,000 businesses formed a coalition for carbon pricing during the United Nations Climate Summit in September 2014, held at the invitation of the UN Secretary-General. The goal of the coalition is to promote productive dialogue between public and private decision-makers concerning opportunities to extend carbon pricing policies. It has been officially launched on November 30, 2015, on the opening day of COP21. It has been officially launched on November 30, 2015, on the opening day of COP21. Members of the coalition include France, Germany, Mexico, Canada, Chile and Ethiopia. The national low-carbon strategy organises the reduction of greenhouse gas emissions sector by sector. The strategy shares five-year targets with economic players and offers opportunities to better coordinate efforts by drawing on a range of tools where carbon pricing will have a key role to play.

    2017-01-01

    As the TEPCV (Territory with Positive Energy for a Green Growth) call for project has been able to mobilise French territories, this document presents results of a quantitative analysis of more than 1.700 actions which have been financed since 2015 within the frame of this programme. Thus, the authors aimed at characterising territories which have been subsidised by this call for project, and proposed actions, in order to highlight existing discrepancies, or to identify actual impacts of the call for project while taking stated objectives into account, and to propose ways of improvement for a maximum impact on territories and for citizens. The authors first present the TEPCV call for project: objectives, typology of eligible territories, scope, reciprocal commitments. General results on 1.737 actions are then presented: analysis methodology, distribution of actions with respect to priority axes, distribution of financing among priority axes, average financing, action duration, geographical distribution of actions and subsidies. The third part proposes a typology of financed actions for different domains: reduction of energy consumption, reduction of greenhouse gas emissions and of transport-related pollutions, development of a circular economy and a sustainable waste management, production of local renewable energies, protection of biodiversity and landscapes and promotion of a sustainable town planning, and development of education on the environment. Distribution among French regions is also analysed with respect to the same issues. Successful aspects and areas of improvements are discussed

  9. Atomic cranks and levers control sugar ring conformations

    International Nuclear Information System (INIS)

    Zhang Qingmin; Lee, Gwangrog; Marszalek, Piotr E

    2005-01-01

    In this paper we review the conformational analysis of sugar rings placed under tension during mechanical manipulations of single polysaccharide molecules with the atomic force microscope and during steered molecular dynamics simulations. We examine the role of various chemical bonds and linkages between sugar rings in inhibiting or promoting their conformational transitions by means of external forces. Small differences in the orientation of one chemical bond on the sugar ring can produce significantly different mechanical properties at the polymer level as exemplified by two polysaccharides: cellulose, composed of β-1→4-linked D-glucose, and amylose, composed of α-1→4-linked D-glucose. In contrast to β-glucose rings, which are mechanically stable and produce simple entropic elasticity of the chain, α-glucose rings flip under tension from their chair to a boat-like structure and these transitions produce deviations of amylose elasticity from the freely jointed chain model. We also examine the deformation of two mechanically complementary 1→6-linked polysaccharides: pustulan, a β-1→6-linked glucan, and dextran, a α-1→6-linked glucan. Forced rotations about the C 5 -C 6 bonds govern the elasticity of pustulan, and complex conformational transitions that involve simultaneous C 5 -C 6 rotations and chair-boat transitions govern the elasticity of dextran. Finally, we discuss the likelihood of various conformational transitions in sugar rings in biological settings and speculate on their significance

    This note examines the major challenges faced by the energy sector in France in a context of continuous cost increase, of lack of domestic production, of high public expenses for the development of renewable energies, of low energy performance, of financial and regulatory framework which does not favour investments. It also highlights the central role of Europe to face these challenges although the European energy policy still lacks ambition, and is still dominated by the climate issue. It formulates a set of propositions about three main axes: a better management of energy consumption, a promotion of new emerging competitive industrial sectors without weakening the sectors of excellence France possesses in the field of energy, and to make the Europe of energy progress

    This note focuses of the major challenges for the French energy sector within a context of continuous cost increase, and outlines the central role of Europe to face the energy challenges. The authors state proposals under three main themes: a better management of energy consumption, a support to the emergence of new competitive industrial sectors without weakening the existing ones, and make the Europe of energy progress. The authors address the challenge of energy cost increase (a traditionally efficient French energy mix but with costs to increase in the future, a weak energy performance, a financial and regulatory framework not favourable to investments and innovation), discuss the European energy policy which, according to them, lacks ambition (a policy unbalanced by the prevalence of the climate issue, a national independence in contradiction with increasing interdependencies) and then make their proposals

    Full Text Available Currently widely used graphical-analytical methods of analysis largely obsolete, replaced by various analytical methods using computer technology. Therefore, of particular interest is the development of a mathematical model kinetostatical calculation mechanisms in the form of library procedures of calculation for all powered two groups Assyrians (GA and primary level. Before resorting to the appropriate procedure that computes all the forces in the kinematic pairs, you need to compute inertial forces, moments of forces of inertia and all external forces and moments acting on this GA. To this end shows the design diagram of the power analysis for each species GA of the second class, as well as the initial link. Finding reactions in the internal and external kinematic pairs based on equilibrium conditions with the account of forces of inertia and moments of inertia forces (Dalembert principle. Thus obtained equations of kinetostatical for their versatility have been solved by the Cramer rule. Thus, for each GA of the second class were found all 6 unknowns: the forces in the kinematic pairs, the directions of these forces as well as forces the shoulders. If we study kinetostatic mechanism with parallel consolidation of two GA in the initial link, in this case, power is the geometric sum of the forces acting on the primary link from the discarded GA. Thus, the obtained mathematical model kinetostatical calculation mechanisms in the form of libraries of mathematical procedures for determining reactions of all GA of the second class. The mathematical model kinetostatical calculation makes it relatively simple to implement its software implementation.

    Full Text Available This study aims to contribute to the understanding of factors influencing the sustainable farmland management in Niger. Specifically, it examines the determinants of adoption of sustainable land management practices including measures to combat erosion, and the use of manure, residues and fertilizer with a view to support the formulation of efficient land use policies based on evidences given fact that the impact of factors influencing farmland management appears to be specific to each context. The study is based on data from the National Survey of Household Living Conditions and Agriculture of 2011 (ECVMA-2011 analyzed within the framework of multivariate Probit model. The results show that there are unobservable interdependences between the decisions on farmland management practices. Furthermore, several types of factors related to access to physical, human, financial and biophysical capitals as well as infrastructure and services seem to play an important role. In addition, it appears that more security is needed in land tenure for a sustainable farmland management while farmland defragmentation can act negatively on sustainable farmland management.

    Full Text Available One of the biggest problems that have confronted the authorities, whether fiscal, monetary, either along the time is represented by the generalised increase in prices (inflation, which is why it is not considered good at the level of an economy, because it is presented as a nominal increase of PIB, namely the erosion of the economy as a whole, not least, to generate macroeconomic imbalances The inflation creates pressure not only on monetary plan, and the plan as general economic, political and social. This, in addition to generating a sharp decline in savings, discourages investment and favors moving the capital in assets that generate real revenue.

  20. The bioscience revolution & the biological weapons threat: levers & interventions

    Directory of Open Access Journals (Sweden)

    Martin Greg

    2009-02-01

    Full Text Available Abstract In December 2008, the US Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism, released a report, World At Risk. The Report points to the fact that, not only is the use of a weapon of mass destruction in a terrorist attack before the end of 2013, more likely than not, but also to the fact that terrorists are more likely to be able to obtain and use biological weapons than nuclear. This paper examines the recommendations of the report in the context of the historic and geopolitical changes, in particular globalization. The authors highlight the "dual-use" dilemma, as described in the report, as the paradoxical use of technology developed for the benefit of mankind being used for sinister purposes. The mitigation of such a threat lies in broad stakeholder involvement and cooperation, including non-state actors, governments and the bio-tech industry itself. The importance of vigilance measures within the life science community is emphasized and, the authors propose, could include a web-based didactic course in bioterrorism and weapons of mass destruction identification. The site could outline safety protocols, have detailed disaster management tutorials, and could be specifically tailored for different subsets of industry and health professionals. The paper concludes with an endorsement of a multi-pronged approach including strong international guidelines and intelligence cooperation and preparatory measures such as the wide-spread use of detection systems as well as diagnostic decision support systems for bioterrorism detection at the local level.

    The Fernald Preserve is a former uranium-processing plant that underwent extensive remediation pursuant to CERCLA and is now managed by the US DOE Office of Legacy Management. While remediation of buildings and soil contamination was completed in 2006, aquifer remediation is ongoing. Paddys Run is a second-order stream that runs to the south along the western side of the Fernald Preserve. The Paddys Run watershed encompasses nearly 41 km2 (16 mi2), including most of the Fernald site. Field personnel conducting routine site inspections in March 2014 observed that Paddys Run was migrating east via bank erosion into the “Pit 3 Swale,” an area of known surface-water contamination. The soil there was certified pursuant to site regulatory agreements and meets all final remediation levels. However, weekly surface-water monitoring is conducted from two puddles within the swale area, when water that exceeds the final remediation levels is present. Paddys Run had migrated east approximately 4 m (13 ft) in 2 years and was approximately 29 m (95 ft) from the sample location. This rapid migration threatened existing conditions that allowed for continued monitoring of the swale area and also threatened Paddys Run water quality. Therefore, DOE and regulators determined that the east bank of Paddys Run required stabilization. This was accomplished with a design that included the following components: relocation of approximately 145 m (475 ft) of streambed 9 m (30 ft) west, installation of a rock toe along the east bank, installation of two cross-vane in-stream grade-control structures, stabilization of a portion of the east bank using soil encapsulated lifts, and regrading, seeding, and planting within remaining disturbed areas. In an effort to take advantage of low-flow conditions in Paddys Run, construction was initiated in September 2014. Weather delays and subsurface flow within the Paddys Run streambed resulted in an interim shutdown of the project area in December 2014. Construction activities resumed in April 2015, with completion in November 2015. To date, this stabilization project has been successful. The regraded bank and streambed have remained stable, and no compromise to installed cross-vanes, the rock toe, or the soil encapsulated lifts has been observed.

  3. Efforts to Improve Efficiency of Extraction Well Operation at the Fernald Preserve, Harrison, Ohio – 16177

    The Fernald Preserve, a former uranium processing facility that produced high-purity uranium metal products during the Cold War, is located in southwest Ohio. The facility became a US Department of Energy Office of Legacy Management (LM) site in November 2006, following completion of the Comprehensive Environmental Response, Compensation, and Liability Act environmental remediation and site restoration (with the exception of groundwater). When the site was turned over to LM, approximately 76.5 ha of the Great Miami Aquifer remained contaminated with uranium above the final remediation level of 30 μg/L. Here, uranium contamination is being removed from groundwater in the Great Miami Aquifer through a pump-and-treat operation, which is predicted to continue until 2033. Twenty extraction wells pump about 30 million liters per day. Operation of the system is impacted by iron in the groundwater that promotes iron fouling of the well pumps, motors, and screens. The design of the well field evolved over 21 years and reflected a conservative system that could respond to a wide range of pumping conditions. For instance, some of the extraction wells were sized with pumps and motors that would allow the well to pump up to 1890 L/min (500 gpm) if warranted. The added flexibility, though, came at the cost of operational efficiency. We describe the efforts that have been taken by LM since the Fernald site was transferred to LM to mitigate the operational impacts from the iron fouling aquifer conditions and improve the efficiency of the well-field operation. Variable-frequency drives were installed at six wells to replace flow control valves. Several wells with oversized pumps and motors were changed from 24-hour per day operation to 8-hour per day operation to allow the pumps to operate closer to their design flow rates. Pumps and motors were “right-sized” at many wells to improve pumping efficiency. The process used to rehabilitate (or clean) well screens was improved, and a process was developed to clean pumps without having to pull them from the well. To reduce pressure drops, improvements were also made to the configuration of the discharge piping. A new control system was installed for each well to allow local control and local tracking of energy used. The amount of energy used daily compared to number of gallons pumped provides a method to assess pump performance and determine when action is necessary to restore well pump efficiency. Additionally, the metrics being employed to help quantify well-field efficiency improvements are described, and the benefits achieved by proactively managing the pump-and-treat operation are presented.

    The local properties of the families of algebraic subsets W g in the Birkhoff strata Σ 2g of Gr (2) containing the hyperelliptic curves of genus g are studied. It is shown that the tangent spaces T g for W g are isomorphic to the linear spaces of 2-coboundaries. Particular subsets in W g are described by the integrable dispersionless coupled KdV systems of hydrodynamical type defining a special class of 2-cocycles and 2-coboundaries in T g . It is demonstrated that the blows-ups of such 2-cocycles and 2-coboundaries and gradient catastrophes for associated integrable systems are interrelated. (paper)

    2000-01-01

    The paper provides an overview of the main features of a Vehicle Market Model (VMM) which estimates changes to vehicle stock/kilometrage, fuel consumed and CO 2 emitted. It is disaggregated into four basic vehicle types. The model includes: the trends in fuel consumption of new cars, including the role of fuel price: a sub-model to estimate the fuel consumption of vehicles on roads characterised by user-defined driving cycle regimes; procedures that reflect distribution of traffic across different area/road types; and the ability to vary the speed (or driving cycle) from one year to another, or as a result of traffic growth. The most significant variable influencing fuel consumption of vehicles was consumption in the previous year, followed by dummy variables related to engine size. the time trend (a proxy for technological improvements), and then fuel price. Indeed the effect of fuel price on car fuel efficiency was observed to be insignificant (at the 95% level) in two of the three versions of the model, and the size of fuel price term was also the smallest. This suggests that the effectiveness of using fuel prices as a direct policy tool to reduce fuel consumption may he limited. Fuel prices may have significant indirect impacts (such as influencing people to purchase more fuel efficient cars and vehicle manufacturers to invest in developing fuel efficient technology) as may other factors such as the threat of legislation.

  14. The HR factor: codes of conduct and gender issues as levers of innovation in geosciences

    Science.gov (United States)

    Rubbia, Giuliana

    2014-05-01

    Professional geosciences organizations which support governments, industry and academic institutions in setting standards for communication, responsible use of geosciences information and continuing professional development do have codes of professional conduct, binding their members. "The geologist is responsible for the impression he gives of his profession in the opinion of those around him and of the public at large" reads one principle of the Code of Professional Conduct of the European Federation of Geologists. Several higher education institutions and public research bodies inspire their regulations to the European Charter of Researchers. In strengthening the relationships of professional organizations with industry, society and academy, it becomes interesting to highlight similarities and fruitful points of contacts between codes of professional ethics and the Charter of Researchers. Ethical principles, professional responsibility and attitude, accountability, dissemination and exploitation of results, public engagement, continuing professional development are some of the remarkable principles. Gender issues are also vital, as starting point to rethink processes in the knowledge society. Structural changes in institutions to improve excellence in research need more women in decision-making bodies, practices of work-family balance and codes of conduct which prevent hidden discriminations. In communication of natural hazards that have societal impact, the diversity management of both target public and communicators can make the difference between a generic communication and an effective one which is more tailored to information needs of women and men acting in the society.

  15. Climate Change after Cancun: An Agreement on Principles, but lacking Levers of Change

    International Nuclear Information System (INIS)

    Delbosc, A.; De Perthuis, Ch.

    2011-01-01

    Climate change and its potentially serious consequences for our planet first appeared on the agenda of major international negotiations at the Rio Summit in 1992. Arduous negotiation ensued, culminating in the Kyoto Protocol in 1997, which set quantified targets for the reduction of greenhouse gas emissions to 2012. Since then, the configuration of the highly complex negotiations (on account of the large number of participants and disparity of economic situations) has changed a great deal, as could be seen at the Copenhagen conference of December 2009 and, more recently, the agreement struck at Cancun in late 2010. Anais Delbosc and Christian de Perthuis, close observers of climate-related economic issues, sum up the state of international climate negotiation in this article. Where have we got to? How have the discussions developed? What are the points of agreement and disagreement? What economic mechanisms have been put in place and so on? After reviewing the history, Delbosc and de Perthuis outline the Cancun agreement, before looking in more detail at a 'variable geometry system of commitment'. They show, in particular, how difficult it is to compare the commitments made by the various parties to the negotiations. However, they do stress that the developed countries are, in general, falling short of the recommendations of the Intergovernmental Panel on Climate Change. They go on to formulate a number of proposals designed to take the commitment to reducing greenhouse gas emissions further, for example by strengthening and unifying the system of measurement and verification of how the various countries are meeting the targets to which they have committed themselves, while nonetheless taking account of their varying situations. Lastly, they propose a more efficient use of the various existing economic instruments, and go on to remind us of the weaknesses that were not resolved by the Cancun agreement, which the Durban Conference, scheduled for late 2011, will have to strive to overcome.

    The development of the use of light with medical purposes, constitute the fundamental basis for the introduction of the laser radiation in medicine. The magnificent results obtained and the amplification of the number of pathologies that can be treated with it, led to the introduction in 1985 of this technology in Cuban hospitals. However, the price of available commercial systems in the market was prohibitive for us, reason for which it was organized a national program that allowed the design and production of this kind of medical equipment, which is being carried out by our center (CEADEN). This technique is known as Low Level Laser Therapy (LLLT). Used for more than four decades, its main goal is to achieve beneficial effects on the human body, like analgesic and anti-inflammatory. It makes damaged soft tissues heal faster, offers a reparative effect on the nervous tissue, muscular tissue, soft tissue, and skin, tissue regeneration, cellular and mitochondrial ATP multiplication, increases the vascular activity, activates the immunological system, and so on. Laser therapy in Cuba has been used in different medical specialties. (Author)

Key phases in HR and organisation management: - The first D and D experience, the learning curve ramp-up - To begin any project, you usually try to benefit from benchmark of similar projects to be able to build up the first scenario, by using the best practices. The first experimental team consisted of operators who already had experienced dismantling at least once in the course of their career. This first dismantling operation is preferably to be conducted on an installation relatively poorly contaminated. This was to implement the correct techniques thus reducing the consequences of a possible unforeseen event. The capitalisation on the return on experience The success of this first dismantling site operation allowed us to implement a process of experience feedback to build the scenarios and the operating procedures of the following sites. In particular, targeted safety-security stop points are positioned for validation on the operations by people responsible for safety and security

    Full Text Available The purpose of the study was to determine the level of proinflammatory cytokines: IL-12, IL-8 and IFNγ, neopterin and lipopolysaccharide-binding protein in the serum of patients with acute brucellosis before and after antibiotic therapy. The clinical data from 32 patients with laboratory-confirmed diagnosis — “acute brucellosis” admitted to the diagnosis, treatment and examination of occupational diseases brucellosis GBUZ SC “City Clinical Hospital No. 2”, the city of Stavropol were used in the study. The concentrations IL-12, IL-8, IFNγ cytokines and acute-phase proteins in serum was determined by ELISA. In the acute phase of brucellosis infection (before treatment had high levels of pro-inflammatory cytokines IL-8 and IFNγ, but despite holding a course of antibiotic treatment in the serum of patients with preserved high levels of IL-8, indicative of active inflammation in the absence of clinical manifestations. IL-12 level, a key cytokine in the initiation of lymphocyte-dependent immune response was lower than in the control group. Evaluation of the cytokine status (IL-8, IL-12, IL-18 and proteins of acute inflammation phase (neopterin and lipopolysaccharide-binding protein will provide valuable information for monitoring the effect of pharmacotherapy of acute brucellosis. Indicators of lipopolysaccharide-binding protein and neopterin in the serum of patients with brucellosis should be considered as a marker of inflammatory activity and as a predictor of outcome of acute brucellosis.

  3. Corporate Governance, Essential Lever of the Policy for Stockholders Wealth Maximization and its Contemporary Complements

    Directory of Open Access Journals (Sweden)

    Liliana Feleaga

    2006-10-01

    Full Text Available After the Second World War, in USA and in the capitalist Europe, a new economic growth regime emerges, known under the name of: the “ford regime”. This regime is based on four main institutional issues: the “ford” wage proportion – which organises the sharing of productivity gains; the active economic policies – budget and monetary ones; the “providence” status – given by a social security system based on social classes and generations’ solidarity; financial systems – meant to ensure the financing of the productive capital accumulation through bank credits. Beginning with the 70’s, the international finances raised their powers within a globalization context. The financial globalization is a process of capital markets’ interaction both at a national and international level – a fact that leads to a world unified cash flow market. Corporate governance is often presented as one of the key institutions of the new capitalism. The theoretical and classical hypothesis, which lies at the base of the Anglo-Saxon governance model, is the one saying that a company’s managers and shareholders have opposite interests. The managers are seeking to take advantage of their status and financial powers because of the inside-business information they hold, all by damaging the shareholders. The “agency theory” is meant either to explain and detail the organisational models as ways to solve conflicts or reduce involved costs (all leading to a “positive agency theory” -PAT, or to allow the reduction of these conflicts’ costs (leading to a “normative/prescriptive agency theory”. The new corporate governance models have as objective the reduction of the informational asymmetry, and of guiding the business leaders towards managing the company in the interests of the shareholders by placing all operations in the area of maximising the value per share. Beyond this approach, many countries adopt a governance model where the company is seen as a social construction, resulting from the interaction of all participating parties. In this case, the main idea is that if on short-term, the company doesn’t focus on maximising exclusively the shareholders’ interests, the economic entity will not be able to actually develop, and on long-term this would have a negative impact on the shareholders.

  6. Carbon righteousness: how to lever pro-poor benefits from REDD+

    Energy Technology Data Exchange (ETDEWEB)

    Scwarte, Christoph [Foundation for International Environmental Law and Development(United Kingdom); Mohammed, Essam Yassin

    2011-07-15

    A growing focus on mitigating climate change by reducing emissions from deforestation and forest degradation (REDD and REDD+) is prompting the creation of a new form of private property — the 'carbon right' — that can be bought and sold in domestic or international markets. But to make REDD+ work for the poor, carbon trading schemes will have to ensure that a wide range of forest-dependent groups and communities benefit. In part, this means carefully assessing how carbon rights are assigned — to ensure they support the rural poor who rarely hold formal land ownership or tenure rights but who are key players in putting sustainable forest management into practice on the ground. It also means rethinking eligibility criteria for REDD+ projects so that they include economic, social and environmental standards and co-benefits.

  8. Levers supporting tariff growth for water services: evidence from a contingent valuation analysis.

    Guerrini, Andrea; Vigolo, Vania; Romano, Giulia; Testa, Federico

    2018-02-01

    The backwardness of the water utilities sector necessitates urgent investment in infrastructure to improve water quality and efficiency in water supply networks. A policy of tariff growth represents the main source to sustain such investments. Therefore, customer engagement in the form of willingness to pay (WTP) is highly desirable by water utilities to obtain social legitimization and support. This study examines the determinants of consumers' WTP for improvement programs for three drinking water issues: quality of water sources, renewal of water mains, and building of new wastewater treatment plants. The study is based on a survey conducted among a sample of 587 customers of a water utility located in the province of Verona in the north of Italy. The contingence valuation method is used to measure WTP. Specifically, an ordinal logistic regression model yields the following significant determinants of WTP: quality of water and services provided, preference for privatization of the water utility, sustainable consumption of water, and some socio-demographic variables. The findings provide interesting insights into the drivers of WTP as well as managerial recommendations for water utilities. In particular, the findings show that water utilities need to improve service and water quality to increase customers' acceptance of tariff growth. In addition, utilities should invest in customer education and communication activities focusing on specific age groups (e.g., older customers) to enhance their WTP. Finally, communication strategies should reinforce the possible role of liberalization and privatization in supporting infrastructure investments. Copyright © 2017 Elsevier Ltd. All rights reserved.

  9. Tidal wave phenomenon as a lever of tourist development in Greece-Halkis case

    Directory of Open Access Journals (Sweden)

    Stefanos, Karagiannis

    2006-01-01

    Full Text Available Tourist season in Halkis is nowadays limited to the three summer months offering a resort for weekend tourists (Athens-Halkis. Halkis is given the opportunity to improvise and illustrate its cultural and historical elements that constitute her uniqueness by establishing a local development programme that would include alternate tourism forms. This proposal regarding the tourist development of Halkis through tidal phenomena is primarily an alternative tourist development model. It differs from current development standards characterized by inequality, environmental and cultural degradation. This is based on the assumption that proposing an alternative tourism form in Halkis would lead to the initiation and exploitation of factors that are disregarded nowadays, that could ignite the tourist rebirth of this area. The creation of new employment positions and the amelioration of life conditions in this town could prevent the constant escape of the vital work-force to Athens and Piraeus. The success of the tourist development through the tidal phenomenon can be considered either a complete solution or an alterna-tive model. This may be unique from the tourist aspect, as the tidal phenomenon of Euripus could be the attraction pole, for a great number of people because this tourist forms (observation of a unique yet in-teresting natural phenomenon is contradictory to luxury. Simultaneously, the Mediterranean nutrition could be co-depicted, by offering the opportunity to the tourist to become more intimate with local prod-ucts. This would help people understand the importance of Euripus tidal phenomenon for the tourist development of Halkis

  10. Quantum variational measurement and the optical lever intracavity topology of gravitational-wave detectors

    International Nuclear Information System (INIS)

    Khalili, F. Ya.

    2007-01-01

    The intracavity topologies of laser gravitational-wave detectors proposed several years ago are the promising way to obtain sensitivity of these devices significantly better than the Standard Quantum Limit (SQL). In essence, the intracavity detector is a two-stage device where the end mirrors displacement created by the gravitational wave is transferred to the displacement of an additional local mirror by means of the optical rigidity. The local mirror positions have to be monitored by an additional local meter. It is evident that the local meter precision defines the sensitivity of the detector. To overcome the SQL, the quantum variational measurement can be used in the local meter. In this method a frequency-dependent correlation between the meter backaction noise and measurement noise is introduced, which allows us to eliminate the backaction noise component from the meter output signal. This correlation is created by means of an additional filter cavity. In this article the sensitivity limitations of this scheme imposed by the optical losses both in the local meter itself and in the filter cavity are estimated. It is shown that the main sensitivity limitation stems from the filter cavity losses. In order to overcome it, it is necessary to increase the filter cavity length. In a preliminary prototype experiment, an approximate 10 m long filter cavity can be used to obtain sensitivity approximately 2-3 times better than the SQL. For future Quantum Non-Demolition (QND) gravitational-wave detectors with sensitivity about 10 times better than the SQL, the filter cavity length should be within kilometer range

  14. Behaviour as a Lever of Ecological Transition? Understanding and Acting on Individual Behaviour and Collective Dynamics

    International Nuclear Information System (INIS)

    Martin, Solange; Gaspard, Albane

    2017-01-01

    Beyond broad policy declarations, the implementation of ecological transition - which consists mainly in curbing consumption of energy and raw materials in our societies - requires substantial behavioural change at the collective, but also, quite obviously, the individual level. Yet, though there is general consensus around the principle of embarking on the path to transition, things get more complicated when it comes to changing our practices and habits. Can we act on individual behaviour and collective dynamics in respect of this particular aim of ecological transition, and, if so, how are we to go about it? Solange Martin and Albane Gaspard have examined this question for the French Environment and Energy Management Agency (ADEME) and offer us the fruit of their labours here. They show, for example, how the social and human sciences help to understand behaviour both at the individual level and in its collective dimensions, and they outline different possible lines of action to modify it. But, given the entanglement between various levels, it is essential, if we are to act effectively on behaviour, to combine approaches, tools and actors, and to analyse and understand social practices thoroughly before implementing political projects or measures

    The authors propose a synthesis of a study on the Indonesian energy policy, its consequences and perspectives for the economic development of the country. Indonesia chose a development model based on the valorisation of its rich natural capital (oil, gas, coal), but however became oil importer, and has been unable until now to take a full advantage of its energetic assets. The authors describe this situation in which the growth trajectory depends on the energetic future, energy is a major budgetary issue, and the global status of energy exporter mitigates external risks in terms of financing and cash. They also outline that the re-distribution of this energetic wealth is to be put into question again

    2015-04-01

    To describe and examine the factors that most facilitate and impede the provision of healthy foods in a complex institutional food system. Comparative case study of three institutional food settings in New York City. Document review and interviews with relevant city government staff. Factors that facilitate and impede the provision of healthy food vary across institutional food settings, and particularly between centralized and decentralized settings. Generally pro-health factors include centralized purchasing and the ability to work with vendors to formulate items to improve nutritional quality, though decentralized purchasing may offer more flexibility to work with vendors offering healthier food items and to respond to consumer preferences. Factors most often working against health in more centralized systems include financing constraints that are unique to particular settings. In less centralized systems, factors working against health may include both financing constraints and factors that are site-specific, relating to preparation and equipment. Making changes to institutional food systems that will meaningfully influence public health requires a detailed understanding of the diverse systems supporting and shaping public food provision. Ultimately, the cases in this study demonstrate that agency staff typically would like to provide healthier foods, but often feel limited by the competing objectives of affordability and consumer preference. Their ability to address these competing objectives is shaped by a combination of both forces external to the institution, like nutritional regulations, and internal forces, like an agency's structure, and motivation on the part of staff.

    2018-03-01

    Publicly funded healthcare forms an intricate part of government spending in most Organisation for Economic Co-operation and Development (OECD) countries, because of its reliance on entitlements and dedicated revenue streams. The impact of budgetary rules and procedures on publicly funded health care might thus be different from other spending categories. In this study we focus on the potential of fiscal rules to contain these costs and their design features. We assess the relationship between fiscal rules and the level of public health care expenditure of 32 (OECD) countries between 1985 and 2014. Our dataset consists of health care expenditure data of the OECD and data on fiscal rules of the International Monetary Fund (IMF) for that same period. Through a multivariate regression analysis, we estimate the association between fiscal rules and its subcategories and inflation adjusted public health care expenditure. We control for population, Gross Domestic Product (GDP), debt and whether countries received an IMF bailout for the specific period. In all our regressions we include country and year fixed effects. The presence of a fiscal rule on average is associated with a 3 % reduction of public health care expenditure. Supranational balanced budget rules are associated with some 8 % lower expenditure. Health service provision-oriented countries with more passive purchasing structures seem less capable of containing costs through fiscal rules. Fiscal rules demonstrate lagged effectiveness; the potential for expenditure reduction increases after one and two years of fiscal rule implementation. Finally, we find evidence that fiscal frameworks that incorporate multi-year expenditure ceilings show additional potential for cost control. Our study shows that there seems a clear relationship between the potential of fiscal rules and budgeting health expenses. Using fiscal rules to contain the level of health care expenditure can thus be a necessary precondition for successful strategies for cost control.

    In Brazil ostriches farming began at the end of 20th Century, to supply the international market of meat, feathers and leather. Feathers are economically important to industry and artisanal sectors. Lice can cause intense pruritus that depending on the intensity of infestation can lead to depreciation of feathers. In Rio de Janeiro there are unknown species of lice infesting ostriches. Thus the objective of this study was to identify the lice that happen in birds from commercial farms in the Municipality of Três Rios. From 2003 to 2006 ostriches were monthly examined for the presence of ectoparasites. When infestations were detected some feathers were removed, placed into plastic bags and sent to the laboratory for further analysis. After removed from feathers, ectoparasites were examined using a stereoscope, followed by clarification in 10% potassium hydroxide and dehydrated in ethanol. Permanent slides were mounted in natural Canada balsam for observation in optical microscope. Based on observed characteristics, it was possible to determine that collected specimens belong to the species Struthiolipeurus rheae.

    2015-12-01

    Full Text Available The Recovery Strategy for the Woodland Caribou (Rangifer tarandus caribou, Boreal Population in Canada (EC, 2012, identifies coordinated actions to reclaim woodland caribou habitat as a key step to meeting current and future caribou population objectives. Actions include restoring industrial landscape features such as roads, seismic lines, pipelines, cut-lines, and cleared areas in an effort to reduce landscape fragmentation and the changes in caribou population dynamics associated with changing predator-prey dynamics in highly fragmented landscapes. Reliance on habitat restoration as a recovery action within the federal recovery strategy is high, considering all Alberta populations have less than 65% undisturbed habitat, which is identified in the recovery strategy as a threshold providing a 60% chance that a local population will be self-sustaining. Alberta’s Provincial Woodland Caribou Policy also identifies habitat restoration as a critical component of long-term caribou habitat management. We review and discuss the history of caribou habitat restoration programs in Alberta and present outcomes and highlights of a caribou habitat restoration workshop attended by over 80 representatives from oil and gas, forestry, provincial and federal regulators, academia and consulting who have worked on restoration programs. Restoration initiatives in Alberta began in 2001 and have generally focused on construction methods, revegetation treatments, access control programs, and limiting plant species favourable to alternate prey. Specific treatments include tree planting initiatives, coarse woody debris management along linear features, and efforts for multi-company and multi-stakeholder coordinated habitat restoration on caribou range. Lessons learned from these programs have been incorporated into large scale habitat restoration projects near Grande Prairie, Cold Lake, and Fort McMurray. A key outcome of our review is the opportunity to provide a unified approach for restoration program planning, best practices, key performance indicators, and monitoring considerations for future programs within Canada.

This alignment begins with the institutional mission and the message it conveys about the priorities of the institution to potential applicants, community, staff, and faculty. The traditional themes of education, research, and service dominate most medical school mission statements. The emerging themes of physician maldistribution, overall primary-care physician shortage, diversity, and cost control are cited less frequently. The importance and salience of having administrative leaders with an explicit commitment to workforce and student diversity is a prominent and pivotal factor in the medical literature on the subject. Organizational leadership shapes the general work climate and expectations concerning diversity, recruitment, and retention. Following the Bakke decision, individual medical schools, supported by the Association of American Medical Colleges, worked to expand the frame of reference for evaluating applicants for medical school. These efforts have come together under the rubric of “holistic review”, permitted by the US Supreme Court in 2003. A large diverse-applicant pool is needed to ensure the appropriate candidates can be chosen for the incoming medical school class.

    Corsaro, Nicholas; Brunson, Rod K

    2013-03-01

    Police agencies across the globe enforce laws that prohibit drug transportation, distribution, and use with varying degrees of effectiveness. Within the United States, law enforcement strategies that rely on partnerships between criminal justice officials, neighbourhood residents, and social service providers (i.e., collaborative implementation) have shown considerable promise for reducing crime and disorder associated with open-air drug markets. The current study examines a comprehensive police enforcement strategy conducted in Peoria, Illinois (USA) designed to reduce patterns of crime and violence associated with an open-air drug market in a specific neighbourhood. Change in neighbourhood crime was assessed using Autoregressive Integrated Moving Average (ARIMA) interrupted time series analysis. Further, target area residents were surveyed to gauge their awareness of the police intervention as well as perceived changes in local crime patterns. Analyses indicate that the intervention did not produce significant changes in neighbourhood crime offense rates between pre- and post-intervention periods. In addition, the majority of surveyed residents within the target area did not demonstrate an awareness of the intervention nor did they report perceived changes in local crime patterns. Study findings suggest that police-led approaches in the absence of high levels of community awareness and involvement may have less capacity to generate crime-control when focusing on open-air drug markets. We propose that police agencies adopting this strategy invest considerable resources toward achieving community awareness and participation in order to increase the potential for attaining significant and substantive programmatic impact.

    This report discusses the challenges of energy imports and energy-oriented renovation of buildings, identifies negative externalities which are not taken in the RT2012 regulation into account, outlines the potential associated with new dwellings, and proposes simple solutions to integrate renewable energies in new dwellings and to reverse the decline of geothermal energy (this sector is now in a critical situation). The authors propose to consider geothermal energy in the same way as heat networks and wood in the RT2012 regulation. They identify the conditions for the development of geothermal energy and of other renewable energies. After an overview of the situation (economic challenge, environmental context, energy-oriented renovation of the existing stock, impact of the regulatory calculation of the construction market), the authors notably present the calculation of a specific index, and describe how to take the production of renewable energies into account in various calculations

    The changes in concentration, total content of histones and relative proportion of individual histone fractions in intact and regenerating liver were followed in rats after administration of hepatoprotective agents flavobion and thioctacid and after whole-body gamma irradiation with a dose 5.7 Gy. Thioctacid alone caused an increase in histone concentration in intact liver whereas flavobion alone did not produce significant quantitative changes. Irradiation alone decreased markedly the concentration and total content of histones in intact as well as regenerating liver of unprotected rats. Administration of thioctacid or flavobion protected from these quantitative histone changes or alleviated them consideradly. In relative proportion of individual histone fractions, the most profound changes were found in H1 histone after flavobion application

  6. Promoting healthy diets and tackling obesity and diet-related chronic diseases: what are the agricultural policy levers?

    Science.gov (United States)

    Hawkes, Corinna

    2007-06-01

    Diet-related chronic diseases are now a serious global public health problem. Public health groups are calling for the agricultural sector to play a greater role in tackling the threat. To identify potential points of policy intervention in the agricultural sector that could be leveraged to promote healthy diets and tackle obesity and diet-related chronic diseases. A review of the literature on the dietary implications of agriculture, a conceptual analysis of the issues, and the identification of relevant examples. There are two main potential points of intervention in the agricultural sector that could be leveraged to promote healthy diets: agricultural policies and agricultural production practices. Agricultural policies and practices affect diet through their influence on food availability, price, and nutrient quality, which in turn affects food choices available to consumers. Agricultural policies amenable to intervention include input, production, and trade policies; agricultural production practices amenable to intervention include crop breeding, crop fertilization practices, livestock-feeding practices, and crop systems diversity. It is well-known that agricultural policies and production practices influence what farmers choose to grow. Agricultural policies and production practices could also play a role in influencing what consumers choose to eat. To identify how agricultural policies and practices can usefully contribute toward promoting healthy diets and tackling obesity and diet-related chronic diseases, health policymakers need to examine whether current agricultural policies and production practices are contributing to-or detracting from-efforts to attain dietary goals; where and how could agricultural intervention help achieve dietary goals; and whether there are trade-offs between these interventions and other important concerns, such as undernutrition and the livelihoods of agricultural producers. Given the potential of agriculture to contribute to large-scale, population-level dietary improvements, these questions warrant closer attention from health policymakers.

  7. Jaw lever analysis of Hawaiian gobioid stream fishes: a simulation study of morphological diversity and functional performance.

    Science.gov (United States)

    Maie, Takashi; Schoenfuss, Heiko L; Blob, Richard W

    2009-08-01

    Differences in feeding behavior and performance among the five native Hawaiian gobioid stream fishes (Sicyopterus stimpsoni, Lentipes concolor, Awaous guamensis, Stenogobius hawaiiensis, and Eleotris sandwicensis) have been proposed based on the skeletal anatomy of their jaws and dietary specialization. However, performance of the feeding apparatus likely depends on the proportions and configurations of the jaw muscles and the arrangement of the jaw skeleton. We used a published mathematical model of muscle function to evaluate potential differences in jaw closing performance and their correlations with morphology among these species. For example, high output force calculated for the adductor mandibulae muscles (A2 and A3) of both A. guamensis and E. sandwicensis matched expectations based on the morphology of these species because these muscles are larger than in the other species. In contrast, Stenogobius hawaiiensis exhibited an alternative morphological strategy for achieving high relative output forces of both A2 and A3, in which the placement and configuration of the muscles conveyed high mechanical advantage despite only moderate cross-sectional areas. These differing anatomical pathways to similar functional performance suggest a pattern of many-to-one mapping of morphology to performance. In addition, a functional differentiation between A2 and A3 was evident for all species, in which A2 was better suited for producing forceful jaw closing and A3 for rapid jaw closing. Thus, the diversity of feeding performance of Hawaiian stream gobies seems to reflect a maintenance of functional breadth through the retention of some primitive traits in combination with novel functional capacities in several species.

    Full Text Available No Brasil, a criação de avestruzes foi iniciada no final do Século XX, para suprir o mercado internacional de carne, plumas e couro. As plumas têm importância econômica nos setores industrial e artesanal. Os piolhos podem causar prurido intenso, que, dependendo da intensidade de infestação, pode levar à depreciação das plumas. No Estado do Rio de Janeiro, são desconhecidas as espécies de piolhos que infestam avestruzes. Assim, o objetivo deste trabalho foi identificar os piolhos que ocorrem nas aves pertencentes a um criatório comercial no Município de Três Rios. Nos anos de 2003 a 2006, mensalmente, as avestruzes foram examinadas, para verificar a presença de ectoparasitos. Quando constatada a infestação, algumas plumas foram retiradas, colocadas em sacos plásticos e enviadas ao laboratório para exame. Após serem coletados das plumas, os ectoparasitos foram examinados ao microscópio estereoscópio, clarificados em hidróxido de potássio a 10%, desidratados em álcool etílico e montados em lâmina com balsamo do Canadá natural, para observação em microscópio óptico. Baseando-se na observação das características, foi possível determinar os espécimes coletados como pertencentes à espécie Struthiolipeurus rheae.In Brazil ostriches farming began at the end of 20th Century, to supply the international market of meat, feathers and leather. Feathers are economically important to industry and artisanal sectors. Lice can cause intense pruritus that depending on the intensity of infestation can lead to depreciation of feathers. In Rio de Janeiro there are unknown species of lice infesting ostriches. Thus the objective of this study was to identify the lice that happen in birds from commercial farms in the Municipality of Três Rios. From 2003 to 2006 ostriches were monthly examined for the presence of ectoparasites. When infestations were detected some feathers were removed, placed into plastic bags and sent to the laboratory for further analysis. After removed from feathers, ectoparasites were examined using a stereoscope, followed by clarification in 10% potassium hydroxide and dehydrated in ethanol. Permanent slides were mounted in natural Canada balsam for observation in optical microscope. Based on observed characteristics, it was possible to determine that collected specimens belong to the species Struthiolipeurus rheae.

  9. Coupling effects of refractive index discontinuity, spot size and spot location on the deflection sensitivity of optical-lever based atomic force microscopy

    International Nuclear Information System (INIS)

    Liu Yu; Yang Jun

    2008-01-01

    Atomic force microscopy (AFM) plays an essential role in nanotechnology and nanoscience. The recent advances of AFM in bionanotechnology include phase imaging of living cells and detection of biomolecular interactions in liquid biological environments. Deflection sensitivity is a key factor in both imaging and force measurement, which is significantly affected by the coupling effects of the refractive index discontinuity between air, the glass window and the liquid medium, and the laser spot size and spot location. The effects of both the spot size and the spot location on the sensitivity are amplified by the refractive index discontinuity. The coupling effects may govern a transition of the deflection sensitivity from enhancement to degradation. It is also found that there is a critical value for the laser spot size, above which the deflection sensitivity is mainly determined by the refractive index of the liquid. Experimental results, in agreement with theoretical predication, elucidate the coupling effects

    2016-12-03

    The involvement of patients and the public in healthcare has grown significantly in recent decades and is documented in health policy documents internationally. Many benefits of involving these groups in primary care planning have been reported. However, these benefits are rarely felt by those considered marginalised in society and they are often excluded from participating in the process of planning primary care. It has been recommended to employ suitable approaches, such as co-operative and participatory initiatives, to enable marginalised groups to highlight their priorities for care. This Participatory Learning and Action (PLA) research study involved 21 members of various marginalised groups who contributed their views about access to primary care. Using a series of PLA techniques for data generation and co-analysis, we explored barriers and facilitators to primary healthcare access from the perspective of migrants, Irish Travellers, homeless people, drug users, sex workers and people living in deprivation, and identified their priorities for action with regard to primary care provision. Four overarching themes were identified: the home environment, the effects of the 'two-tier' healthcare system on engagement, healthcare encounters, and the complex health needs of many in those groups. The study demonstrates that there are many complicated personal and structural barriers to accessing primary healthcare for marginalised groups. There were shared and differential experiences across the groups. Participants also expressed shared priorities for action in the planning and running of primary care services. Members of marginalised groups have shared priorities for action to improve their access to primary care. If steps are taken to address these, there is scope to impact on more than one marginalised group and to address the existing health inequities.

    Background At the Children’s Hospital of Georgia (CHOG), we found that outpatient revisits for pediatric asthma were significantly above national norms. According to the NIH, costly hospital revisits for asthma can be prevented through guidelines-based self-management of asthma, central to which, is the use of a written Asthma-Action Plan (AAP). Purpose The asthma services literature has emphasized the role of the healthcare provider in promoting asthma self-management using the AAP, to prevent hospital revisits. On the other hand, the asthma policy literature has emphasized the need for community-based interventions to promote asthma self-management. A gap remains in understanding the extent of leverage that healthcare providers may have in preventing hospital revisits for asthma, through effective communication of AAP in the outpatient setting. Our study sought to address this gap. Methods We conducted a 6-month intervention to implement “patient-and-family-centered communication of the AAP” in CHOG outpatient clinics, based on the “change-management” theoretical framework. Provider communication of AAP was assessed through a survey of “Parent Understanding of the Child’s AAP.” A quasi-experimental approach was used to measure outpatient revisits for pediatric asthma, pre- and post-intervention. Results Survey results showed that provider communication of the AAP was unanimously perceived highly positively by parents of pediatric asthma patients, across various metrics of patient-centered care. However, there were no statistically significant differences in outpatient “revisit behavior” for pediatric asthma between pre- and post-intervention periods after controlling for several demographic variables. Additionally, revisits remained significantly above national norms. Conclusions Results suggest limited potential of “effective provider communication of AAP,” in reducing outpatient revisits for pediatric asthma; and indicate need for broader community-based interventions to address patient life variables impacting self-management and hospital revisits for pediatric asthma. Findings suggest need for a revised “socio-ecological” theoretical framework, and also provide insight into various policy, research, and practice implications for asthma management and control.

    The social, emotional, and mental health benefits associated with gardening have been well documented. However, the processes underlying the relationship between garden participation and improvements in health status have not been sufficiently studied. Using population-based survey data (n = 469 urban residents), objective street environment data, and area-level measures, this research used a path analytic framework to examine several theoretically based constructs as mediators between gardening history and self-reported health. The results showed that garden participation influenced health status indirectly through social involvement with one's community, perceived aesthetic appeal of the neighborhood, and perceived collective efficacy. Gardeners, compared to non-gardeners, reported higher ratings of neighborhood aesthetics and more involvement in social activities, whereas aesthetics and involvement were associated with higher ratings of collective efficacy and neighborhood attachment. Collective efficacy, but not neighborhood attachment, predicted self-rated health. Gardening also directly influenced improved fruit and vegetable intake. The physical and social qualities of garden participation may therefore stimulate a range of interpersonal and social responses that are supportive of positive ratings of health. This research suggests that community planners and health professionals should aim to strengthen the social and aesthetic relationships while designing environments and policies as a way to ignite intermediate processes that may lead to improved health status.

    Masin, Sergio Cesare; Crivellaro, Francesco; Varotto, Diego

    2014-01-01

    The research field of intuitive physics focuses on discrepancies between theoretical and intuitive physical knowledge. Consideration of these discrepancies can help in the teaching of elementary physics. However, evidence shows that theoretical and intuitive physical knowledge may also be congruent. Physics teaching could further benefit from…

  19. Policy Levers Key for Primary Health Care Organizations to Support Primary Care Practices in Meeting Medical Home Expectations: Comparing Leading States to the Australian Experience.

    Science.gov (United States)

    Takach, Mary

    2016-10-01

    Several countries with highly ranked delivery systems have implemented locally-based, publicly-funded primary health care organizations (PHCOs) as vehicles to strengthen their primary care foundations. In the United States, state governments have started down a similar pathway with models that share similarities with international PHCOs. The objective of this study was to determine if these kinds of organizations were working with primary care practices to improve their ability to provide comprehensive, coordinated, and accessible patient-centered care that met quality, safety, and efficiency outcomes-all core attributes of a medical home. This qualitative study looked at 4 different PHCO models-3 from the United States and 1 from Australia-with similar objectives and scope. Primary and secondary data included semi-structured interviews with 26 PHCOs and a review of government documents. The study found that the 4 PHCO models were engaging practices to meet a number of medical home expectations, but the US PHCOs were more uniform in efforts to work with practices and focused on arranging services to meet the needs of complex patients. There was significant variation in level of effort between the Australian PHCOs. These differences can be explained through the state governments' selection of payment models and use of data frameworks to support collaboration and incentivize performance of both PHCOs and practices. These findings offer policy lessons to inform health reform efforts under way to better capitalize on the potential of PHCOs to support a high-functioning primary health foundation as an essential component to a reformed health system.

    Full Text Available The National Endowment for the Humanities (NEH is a federal agency created in 1965 with the mission of “serving the nation by promoting the humanities and giving lessons of history to all Americans.” It finances radio and TV programs on history, music and industry as well as interpretative museum exhibitions and the publishing of catalogs. This article aims at studying one specific type of grant aimed at museums and at exploring the way the compliance with the criteria set by the NEH may affect the organization and contents of exhibitions of tribal museums in particular. It wonders whether the fact of imposing outside scholars (i.e. non-Indian experts is not a means of controlling the interpretation of Native American history and of disguising and furthering the government’s policy of assimilation into the mainstream.

  8. Drug versus sweet reward: greater attraction to and preference for sweet versus drug cues.

    Science.gov (United States)

    Madsen, Heather B; Ahmed, Serge H

    2015-05-01

    Despite the unique ability of addictive drugs to directly activate brain reward circuits, recent evidence suggests that drugs induce reinforcing and incentive effects that are comparable to, or even lower than some nondrug rewards. In particular, when rats have a choice between pressing a lever associated with intravenous cocaine or heroin delivery and another lever associated with sweet water delivery, most respond on the latter. This outcome suggests that sweet water is more reinforcing and attractive than either drug. However, this outcome may also be due to the differential ability of sweet versus drug levers to elicit Pavlovian feeding-like conditioned responses that can cause involuntary lever pressing, such as pawing and biting the lever. To test this hypothesis, rats first underwent Pavlovian conditioning to associate one lever with sweet water (0.2% saccharin) and a different lever with intravenous cocaine (0.25 mg) or heroin (0.01 mg). Choice between these two levers was then assessed under two operant choice procedures: one that permitted the expression of Pavlovian-conditioned lever press responses during choice, the other not. During conditioning, Pavlovian-conditioned lever press responses were considerably higher on the sweet lever than on either drug lever, and slightly greater on the heroin lever than on the cocaine lever. Importantly, though these differences in Pavlovian-conditioned behavior predicted subsequent preference for sweet water during choice, they were not required for its expression. Overall, this study confirms that rats prefer the sweet lever because sweet water is more reinforcing and attractive than cocaine or heroin. © 2014 Society for the Study of Addiction.

    International Nuclear Information System (INIS)

    Goldstein, L.H.; Oakley, D.A.

    1989-01-01

    An autoshaping procedure in which the illumination of a lever was predictive of food reinforcement was used to compare learning in rats with micrencephaly induced by irradiation on the 16th day of gestation and in sham-irradiated controls. Both groups showed equivalent levels of lever-directed activity, and the micrencephalic animals differentiated as well as the control animals between the predictive lever and a nonpredictive lever. The micrencephalic animals were able to redistribute their lever-directed activity when the significance of the levers was reversed and did so more readily than the control animals.

    An autoshaping procedure in which the illumination of a lever was predictive of food reinforcement was used to compare learning in rats with micrencephaly induced by irradiation on the 16th day of gestation and in sham-irradiated controls. Both groups showed equivalent levels of lever-directed activity, and the micrencephalic animals differentiated as well as the control animals between the predictive lever and a nonpredictive lever. The micrencephalic animals were able to redistribute their lever-directed activity when the significance of the levers was reversed and did so more readily than the control animals. Results support the claim that association learning survives either traumatic or developmental neocortical damage and have implications for remedial procedures following both head injury and developmental cerebral pathology in humans.

    Tissue oxygen saturation (SO2) measurements have the potential for far wider use than at present but are limited by device availability and portability for many potential applications. A device based on a small, low-cost general-purpose spectrophotometer (the Harrison device) might facilitate wider use. The aim of this study was to compare the Harrison device with a commercial instrument, the LEA O2C.Measurements were carried out on the forearm and finger of 20 healthy volunteers, using a blood pressure cuff on the upper arm to induce different levels of oxygenation. Repeatability of both devices was assessed, and the Bland-Altman method was used to assess agreement between them.The devices showed agreement in overall tracking of changes in SO2. Test-retest agreement for the Harrison device was worse than for O2C, with SD repeatability of 10.6% (forearm) or 18.6% (finger). There was no overall bias between devices, but mean (SD) difference of 1.2 (11.8%) (forearm) or 4.4 (11.5%) (finger) were outside of a clinically acceptable range.Disagreements were attributed to the stability of the Harrison probe and the natural SO2 variations across the skin surface increasing the random error. Therefore, though not equivalent to the LEA O2C, a probe redesign and averaged measurements may help establish the Harrison device as a low cost alternative.

  16. Voluntarist theology and early-modern science: The matter of the divine power, absolute and ordained.

    Science.gov (United States)

    Oakley, Francis

    2018-03-01

    This paper is an intervention in the debate inaugurated by Peter Harrison in 2002 when he called into question the validity of what has come to be called 'the voluntarism and early-modern science thesis'. Though it subsequently drew support from such historians of science as J. E. McGuire, Margaret Osler, and Betty-Joe Teeter Dobbs, the origins of the thesis are usually traced back to articles published in 1934 and 1961 respectively by the philosopher Michael Foster and the historian of ideas Francis Oakley. Central to Harrison's critique of the thesis are claims he made about the meaning of the scholastic distinction between the potentia dei absoluta et ordinata and the role it played in the thinking of early-modern theologians and natural philosophers. This paper calls directly into question the accuracy of Harrison's claims on that very matter.

    Iversen, I H

    1993-07-01

    In three experiments, access to wheel running was contingent on lever pressing. In each experiment, the duration of access to running was reduced gradually to 4, 5, or 6 s, and the schedule parameters were expanded gradually. The sessions lasted 2 hr. In Experiment 1, a fixed-ratio 20 schedule controlled a typical break-and-run pattern of lever pressing that was maintained throughout the session for 3 rats. In Experiment 2, a fixed-interval schedule of 6 min maintained lever pressing throughout the session for 3 rats, and for 1 rat, the rate of lever pressing was positively accelerated between reinforcements. In Experiment 3, a variable-ratio schedule of 20 or 35 was in effect and maintained lever pressing at a very stable pace throughout the session for 2 of 3 rats; for 1 rat, lever pressing was maintained at an irregular rate. When the session duration was extended to successive 24-hr periods, with food and water accessible in Experiment 3, lever pressing settled into a periodic pattern occurring at a high rate at approximately the same time each day. In each experiment, the rats that developed the highest local rates of running during wheel access also maintained the most stable and highest rates of lever pressing.

  2. Functional states of rat cortical circuits during the unpredictable availability of a reward-related cue.

    Proper performance of acquired abilities can be disturbed by the unexpected occurrence of external changes. Rats trained with an operant conditioning task (to press a lever in order to obtain a food pellet) using a fixed-ratio (1:1) schedule were subsequently placed in a Skinner box in which the lever could be removed randomly. Field postsynaptic potentials (fPSPs) were chronically evoked in perforant pathway-hippocampal CA1 (PP-CA1), CA1-subiculum (CA1-SUB), CA1-medial prefrontal cortex (CA1-mPFC), mPFC-nucleus accumbens (mPFC-NAc), and mPFC-basolateral amygdala (mPFC-BLA) synapses during lever IN and lever OUT situations. While lever presses were accompanied by a significant increase in fPSP slopes at the five synapses, the unpredictable absence of the lever were accompanied by decreased fPSP slopes in all, except PP-CA1 synapses. Spectral analysis of local field potentials (LFPs) recorded when the animal approached the corresponding area in the lever OUT situation presented lower spectral powers than during lever IN occasions for all recording sites, apart from CA1. Thus, the unpredictable availability of a reward-related cue modified the activity of cortical and subcortical areas related with the acquisition of operant learning tasks, suggesting an immediate functional reorganization of these neural circuits to address the changed situation and to modify ongoing behaviors accordingly.

  6. Parallel learning in an autoshaping paradigm.

    Science.gov (United States)

    Naeem, Maliha; White, Norman M

    2016-08-01

    In an autoshaping task, a single conditioned stimulus (CS; lever insertion) was repeatedly followed by the delivery of an unconditioned stimulus (US; food pellet into an adjacent food magazine) irrespective of the rats' behavior. After repeated training trials, some rats responded to the onset of the CS by approaching and pressing the lever (sign-trackers). Lesions of dorsolateral striatum almost completely eliminated responding to the lever CS while facilitating responding to the food magazine (US). Lesions of the dorsomedial striatum attenuated but did not eliminate responding to the lever CS. Lesions of the basolateral or central nucleus of the amygdala had no significant effects on sign-tracking, but combined lesions of the 2 structures impaired sign-tracking by significantly increasing latency to the first lever press without affecting the number of lever presses. Lesions of the dorsal hippocampus had no effect on any of the behavioral measures. The findings suggest that sign-tracking with a single lever insertion as the CS may consist of 2 separate behaviors learned in parallel: An amygdala-mediated conditioned orienting and approach response and a dorsal striatum-mediated instrumental response.

    Repeated exposure to cocaine often leads to tolerance to effects on operant behavior, whereas sensitization often develops to effects on locomotor activity. The purpose of the present set of experiments was to examine if locomotor sensitization to cocaine would develop in the presence or absence of an operant contingency in rats. In Experiment 1, rats lever pressed on an FR schedule of reinforcement, and were administered chronic cocaine. Tolerance to effects of cocaine on lever pressing deve...

  18. Is induction produced by upcoming food-pellet reinforcement the outcome of an increase in overall activity or in operant responding?

    Science.gov (United States)

    Weatherly, Jeffrey N; Arthur, Emily I L; Nurnberger, Jeri T

    2006-01-01

    Researchers have demonstrated that rats reliably increase their rates of pressing a lever for 1% liquid-sucrose reinforcement if they will soon have the opportunity to press a lever for food-pellet reinforcement. In the present experiments, the authors investigated if this increase in response rates occurred because the upcoming food pellets produced an increase in all behaviors (i.e., general arousal) or an increase in only the specific operant response (i.e., lever pressing). The results of Experiments 1 and 2 showed that the appearance of induction in rats' lever pressing for 1% sucrose reinforcement when food-pellet reinforcement was upcoming did not coincide with increases in the frequency of running in a wheel or making a nonreinforced nose-poke response. On the other hand, in Experiment 3, the authors found the appearance of induction coincided with increase nonreinforced lever presses on an adjacent lever. These results shed doubt on the idea that induction is a result of a general increase in all activity, and suggest instead that the increase in responding that occurs during induction is limited to the operant response.

  19. Autoshaping, random control, and omission training in the rat.

    Locurto, C; Terrace, H S; Gibbon, J

    1976-11-01

    The role of the stimulus-reinforcer contingency in the development and maintenance of lever contact responding was studied in hooded rats. In Experiment I, three groups of experimentally naive rats were trained either on autoshaping, omission training, or a random-control procedure. Subjects trained by the autoshaping procedure responded more consistently than did either random-control or omission-trained subjects. The probability of at least one lever contact per trial was slightly higher in subjects trained by the omission procedure than by the random-control procedure. However, these differences were not maintained during extended training, nor were they evident in total lever-contact frequencies. When omission and random-control subjects were switched to the autoshaping condition, lever contacts increased in all animals, but a pronounced retardation was observed in omission subjects relative to the random-control subjects. In addition, subjects originally exposed to the random-control procedure, and later switched to autoshaping, acquired more rapidly than naive subjects that were exposed only on the autoshaping procedure. In Experiment II, subjects originally trained by an autoshaping procedure were exposed either to an omission, a random-control, or an extinction procedure. No differences were observed among the groups either in the rate at which lever contacts decreased or in the frequency of lever contacts at the end of training. These data implicate prior experience in the interpretation of omission-training effects and suggest limitations in the influence of stimulus-reinforcer relations in autoshaping.

  20. Recovery of Pavlovian sign-tracking (autoshaping) following the discontinuation of inter-trial interval food in rats.

    Kearns, David N; Weiss, Stanley J

    2007-07-01

    In pigeons, Pavlovian autoshaped keypecking produced by keylight-food pairings has been eliminated by introducing food during periods between CS presentations (i.e., during the inter-trial intervals). Keypecking eliminated in this manner reappears when the inter-trial USs are discontinued even though the CS is no longer paired with US. The present experiment investigated whether this recovery of responding produced by discontinuing unpaired inter-trial US presentations could be extended to another species, rats, within a Pavlovian sign-tracking paradigm. Rats were initially trained on a procedure where insertion of one retractable lever (CS(+)) was followed, response independently, with food, while insertion of another lever (CS(-)) was not paired with food. Rats quickly came to contact the CS(+) lever at high rates, but contacted the CS(-) lever infrequently. In the next phase, CS(+) was no longer followed by food. Explicitly unpaired food was presented only during the inter-trial intervals when both levers were absent. This treatment essentially eliminated the sign-tracking response. In the final phase, the unpaired inter-trial food presentations were discontinued while both CSs continued to be presented without food. This produced a significant recovery of the sign-tracking elicited by the CS(+) lever, extending the species generality of the Pavlovian resurgence phenomenon that has previously only been reported in pigeons, to rats.

  1. Stimulus- and response-reinforcer contingencies in autoshaping, operant, classical, and omission training procedures in rats.

    Science.gov (United States)

    Atnip, G W

    1977-07-01

    Separate groups of rats received 500 trials of lever-press training under autoshaping (food delivery followed 10-second lever presentations, or occurred immediately following a response); operant conditioning (responding was necessary for food delivery); and classical conditioning (food followed lever presentations regardless of responding). Each group then received 500 trials on an omission procedure in which food was omitted on trials with a response. Another group received 1000 trials on the omission procedure, and a fifth group, random control, received 1000 uncorrelated presentations of lever and food. The autoshaping, operant, and classical groups reached high response levels by the end of initial training. Acquisition was fastest in the autoshaping group. Responding remained consistently low in the control group. The omission group responded at a level between the control group and the other three groups. During omission training, responding in these three groups declined to the omission-group level. During omission training, the rats continued contacting the lever frequently after lever pressing had declined. Response maintenance under omission training seems not to require topographic similarity between the response and reinforcer-elicited consummatory behaviors.

  3. Flexural Stiffness of Myosin Va Subdomains as Measured from Tethered Particle Motion

    Myosin Va (MyoVa) is a processive molecular motor involved in intracellular cargo transport on the actin cytoskeleton. The motor's processivity and ability to navigate actin intersections are believed to be governed by the stiffness of various parts of the motor's structure. Specifically, changes in calcium may regulate motor processivity by altering the motor's lever arm stiffness and thus its interhead communication. In order to measure the flexural stiffness of MyoVa subdomains, we use tethered particle microscopy, which relates the Brownian motion of fluorescent quantum dots, which are attached to various single- and double-headed MyoVa constructs bound to actin in rigor, to the motor's flexural stiffness. Based on these measurements, the MyoVa lever arm and coiled-coil rod domain have comparable flexural stiffness (0.034 pN/nm). Upon addition of calcium, the lever arm stiffness is reduced 40% as a result of calmodulins potentially dissociating from the lever arm. In addition, the flexural stiffness of the full-length MyoVa construct is an order of magnitude less stiff than both a single lever arm and the coiled-coil rod. This suggests that the MyoVa lever arm-rod junction provides a flexible hinge that would allow the motor to maneuver cargo through the complex intracellular actin network. PMID:26770194

    The purpose of the present study was to investigate whether altered longitudinal bending stiffness (LBS) levels of the midsole of a running shoe lead to a systematic change in lower extremity joint lever arms of the ground reaction force (GRF). Joint moments and GRF lever arms in the sagittal plane were determined from 19 male subjects running at 3.5 m/s using inverse dynamics procedures. LBS was manipulated using carbon fiber insoles of 1.9 mm and 3.2 mm thickness. Increasing LBS led to a significant shift of joint lever arms to a more anterior position. Effects were more pronounced at distal joints. Ankle joint moments were not significantly increased in the presence of higher GRF lever arms when averaged over all subjects. Still, two individual strategies (1: increase ankle joint moments while keeping push-off times almost constant, 2: decrease ankle joint moments and increase push-off times) could be identified in response to increased ankle joint lever arms that might reflect individual differences between subjects with respect to strength capacities or anthropometric characteristics. The results of the present study indicate that LBS systematically influences GRF lever arms of lower extremity joints during the push-off phase in running. Further, individual responses to altered LBS levels could be identified that could aid in finding optimum LBS values for a given individual. Copyright © 2014 Elsevier B.V. All rights reserved.

  5. ANALYSIS OF THE INFLUENCE OF A COMPANY’S INDEBTEDNESS ON THE FINANCIAL RISK

    Full Text Available Awareness of indebtedness and financial risk represents a great importance not only for the management of the company but also for creditors, investors, institutional investors, rating agencies, etc. An indebtedness analysis implies its effect on financial risk through financial lever coefficient or the financial lever. A financial lever is a notion originating in physics and it is the force that is applied in order to give a boost of a process or a phenomenon. However, in economics that notion was adapted and can be regarded as the strenght of different financial categories, financial instruments used in order to give a boost in a certain sense to various economic processes or activities in order to achieve the established objectives. More specifically we can say that the financial lever or the financial leverage expresses the impact of the financial structure over the company’s profitability. The research aims at analysing indebtedness and its influence over the financial risk and all the aspects underlined in the present article will prove the assumption that a company's performance and its capacity to produce profit depends mainly on the management and the use of financial resources. The purpose of present article is to highlight the impact of indebtedness over financial risk through the financial lever. The main objectives of the article set out to achieve this purpose are: the theoretical approach of a company's overall indebtedness, the analysis of the financial levers, and the analysis of the positive and negative leverage effects.

    Heightened fiscal constraints, increases in the chronic disease burden and in consumer expectations are among several factors contributing to the global interest in evidence-informed health policy. The present article builds on previous work that explored how the Australian Federal Government applied five instruments of policy, or policy levers, to implement a series of reforms under the Australian National Mental Health Strategy (NMHS). The present article draws on theoretical insights from political science to analyse the relative successes and failures of these levers, as portrayed in formal government evaluations of the NMHS. Documentary analysis of six evaluation documents corresponding to three National Mental Health Plans was undertaken. Both the content and approach of these government-funded, independently conducted evaluations were appraised. An overall improvement was apparent in the development and application of policy levers over time. However, this finding should be interpreted with caution due to variations in evaluation approach according to Plan and policy lever. Tabulated summaries of the success and failure of each policy initiative, ordered by lever type, are provided to establish a resource that could be consulted for future policy-making. This analysis highlights the complexities of health service reform and underscores the limitations of narrowly focused empirical approaches. A theoretical framework is provided that could inform the evaluation and targeted selection of appropriate policy levers in mental health.

  7. Assessment of hydrology, water quality, and trace elements in selected placer-mined creeks in the birch creek watershed near central, Alaska, 2001-05

    Kennedy, Ben W.; Langley, Dustin E.

    2007-01-01

    Executive Summary The U.S. Geological Survey, in cooperation with the Bureau of Land Management, completed an assessment of hydrology, water quality, and trace-element concentrations in streambed sediment of the upper Birch Creek watershed near Central, Alaska. The assessment covered one site on upper Birch Creek and paired sites, upstream and downstream from mined areas, on Frying Pan Creek and Harrison Creek. Stream-discharge and suspended-sediment concentration data collected at other selected mined and unmined sites helped characterize conditions in the upper Birch Creek watershed. The purpose of the project was to provide the Bureau of Land Management with baseline information to evaluate watershed water quality and plan reclamation efforts. Data collection began in September 2001 and ended in September 2005. There were substantial geomorphic disturbances in the stream channel and flood plain along several miles of Harrison Creek. Placer mining has physically altered the natural stream channel morphology and removed streamside vegetation. There has been little or no effort to re-contour waste rock piles. During high-flow events, the abandoned placer-mine areas on Harrison Creek will likely contribute large quantities of sediment downstream unless the mined areas are reclaimed. During 2004 and 2005, no substantial changes in nutrient or major-ion concentrations were detected in water samples collected upstream from mined areas compared with water samples collected downstream from mined areas on Frying Pan Creek and Harrison Creek that could not be attributed to natural variation. This also was true for dissolved oxygen, pH, and specific conductance-a measure of total dissolved solids. Sample sites downstream from mined areas on Harrison Creek and Frying Pan Creek had higher median suspended-sediment concentrations, by a few milligrams per liter, than respective upstream sites. However, it is difficult to attach much importance to the small downstream increase

    2005-01-01

    In this Letter we present (electrically) charged dilatonic black ring solutions of the Einstein-Maxwell-dilaton theory in five dimensions and we consider their physical properties. These solutions are static and as in the neutral case possess a conical singularity. We show how one may remove the conical singularity by application of a Harrison transformation, which physically corresponds to supporting the charged ring with an electric field. Finally, we discuss the slowly rotating case for arbitrary dilaton coupling

  16. The role of the lateral habenula in punishment.

    Science.gov (United States)

    Jean-Richard Dit Bressel, Philip; McNally, Gavan P

    2014-01-01

    The lateral habenula (LHb) is a small epithalamic structure that projects via the fasciculus retroflexus to the midbrain. The LHb is known to modulate midbrain dopamine (DA) neurons, including inhibition of ventral tegmental area (VTA) neurons via glutamatergic excitation of the GABAergic rostromedial tegmental nucleus (RMTg). A variety of lines of evidence show activity in LHb and the LHb-RMTg pathway is correlated with, and is sufficient to support, punishment learning. However, it is not immediately clear whether LHb is necessary for punishment. Here we used a within-subjects punishment task to assess the role of LHb in the acquisition and expression of punishment as well as in aversive choice. Rats that pressed two individually presented levers for pellet rewards rapidly suppressed responding to one lever if it also caused footshock deliveries (punished lever) but continued pressing a second lever that did not cause footshock (unpunished lever). Infusions of an AMPA receptor antagonist (NBQX) into LHb had no effect on the acquisition or expression of this punishment, or on aversive choice, but did increase locomotion. Infusion of the sodium channel blocker bupivacaine likewise had no effect on expression of punishment. However, infusion of the calcium channel blocker mibefradil did affect expression of punishment by significantly decreasing the latency with which rats responded on the punished lever and significantly increasing unpunished lever-pressing. Taken together, these findings indicate that the LHb plays a limited role in punishment, influencing only latency to respond. This role is linked to calcium channel permeability and not AMPA receptor or sodium channel permeability.

  17. The effects of varied extinction procedures on contingent cue-induced reinstatement in Sprague-Dawley rats.

    2013-11-01

    Cue exposure therapy, which attempts to limit relapse by reducing reactivity to cocaine-paired cues through repeated exposures, has had limited success. The current experiments examined cocaine cue-induced anxiogenesis and investigated whether a model of cue exposure therapy would reduce reinstatement of cocaine seeking in rats with a history of cocaine self-administration. Male rats experienced daily intravenous cocaine self-administration. Rats then experienced exposure to either the self-administration context or the context plus noncontingent presentations of cocaine-paired cues. Immediately following exposure, anxiety-like behavior was measured using elevated plus maze and defensive burying tests. In a second group of rats, self-administration was followed by 7 days of exposure to the context, context + noncontingent cue exposure, lever extinction, or cue + lever extinction. All animals then underwent two contingent cue-induced reinstatement tests separated by 7 days of lever extinction. Exposure to noncontingent cocaine-paired cues in the self-administration context increased anxiety-like behavior on the defensive burying test. Animals that experienced lever + cue extinction displayed the least cocaine seeking on the first reinstatement test, and lever extinction reduced cocaine seeking below context exposure or context + noncontingent cue exposure. All animals had similar levels of cocaine seeking on the second reinstatement test. Noncontingent cue exposure causes anxiety, and noncontingent cue and context exposure are less effective at reducing contingent cue-induced reinstatement than lever or lever + cue extinction. These data indicate that active extinction of the drug-taking response may be critical for reduction of relapse proclivity in former cocaine users.

    Data from the Atacama Cosmology Telescope (ACT) and the South Pole Telescope (SPT), combined with the nine-year data release from the WMAP satellite, provide very precise measurements of the cosmic microwave background (CMB) angular anisotropies down to very small angular scales. Augmented with measurements from Baryonic Acoustic Oscillations surveys and determinations of the Hubble constant, we investigate whether there are indications for new physics beyond a Harrison-Zel'dovich model for primordial perturbations and the standard number of relativistic degrees of freedom at primordial recombination. All combinations of datasets point to physics beyond the minimal Harrison-Zel'dovich model in the form of either a scalar spectral index different from unity or additional relativistic degrees of freedom at recombination (e.g., additional light neutrinos). Beyond that, the extended datasets including either ACT or SPT provide very different indications: while the extended-ACT (eACT) dataset is perfectly consistent with the predictions of standard slow-roll inflation, the extended-SPT (eSPT) dataset prefers a non-power-law scalar spectral index with a very large variation with scale of the spectral index. Both eACT and eSPT favor additional light degrees of freedom on top of the Harrison-Zel'dovich model. eACT is consistent with zero neutrino masses, while eSPT favors nonzero neutrino masses at more than 95% confidence.

  19. Inflation and large scale structure formation after COBE

    1992-06-01

    The simplest realizations of the new inflationary scenario typically give rise to primordial density fluctuations which deviate logarithmically from the scale free Harrison-Zeldovich spectrum. We consider a number of such examples and, in each case we normalize the amplitude of the fluctuations with the recent COBE measurement of the microwave background anisotropy. The predictions for the bulk velocities as well as anisotropies on smaller (1-2 degrees) angular scales are compared with the Harrison-Zeldovich case. Deviations from the latter range from a few to about 15 percent. We also estimate the redshift beyond which the quasars would not be expected to be seen. The inflationary quasar cutoff redshifts can vary by as much as 25% from the Harrison-Zeldovich case. We find that the inflationary scenario provides a good starting point for a theory of large scale structure in the universe provided the dark matter is a combination of cold plus (10-30%) hot components.

  20. Increased sign-tracking behavior in adolescent rats.

    DeAngeli, Nicole E; Miller, Sarah B; Meyer, Heidi C; Bucci, David J

    2017-11-01

    An autoshaping procedure was used to test the notion that conditioned stimuli (CSs) gain greater incentive salience during adolescence than young adulthood under conditions of social isolation rearing and food restriction. Rats were single-housed and placed on food restriction during 10 daily training sessions in which a lever (CS + ) was presented then followed immediately by a food unconditioned stimulus (US). A second lever (CS - ) was presented on intermixed trials and was not reinforced. Despite the fact that food delivery was not contingent on the rats' behavior, all rats exhibited behaviors directed towards the lever (i.e., sign-tracking). In the adolescent group, the rate of lever pressing and the percentage of trials with a lever press were higher than in young adults. Initially, group differences were observed when rats were retrained when the adolescents had reached young adulthood. These findings support the hypothesis that cues that come to predict reward become imbued with excessive motivational value in adolescents, perhaps contributing to the hyper-responsiveness to reward-related stimuli typically observed during this period of development. © 2017 Wiley Periodicals, Inc.

  1. Food deprivation enhances both autoshaping and autoshaping impairment by a latent inhibition procedure.

    Sparber, S B; Bollweg, G L; Messing, R B

    1991-02-01

    The influence of food deprivation on acquisition of autoshaped operant behavior was measured. In one study separate groups of young, male rats that were deprived to 75%, 80%, 85%, 90%, and 95% of ad lib weight were subjected to an autoshaping procedure in which a 6 s delay was interposed between lever retraction (which occurred when rats made a lever touch, or automatically after 15 s) and food pellet delivery. In a second study, groups of rats were deprived to 80% or 90% of ad lib weight prior to testing in a latent inhibition variation of the same autoshaping procedure. This was done to determine if greater food deprivation would enhance learning which, because of the latent inhibition manipulation, is manifest as less lever-directed behavior. Greater food deprivation was associated both with fast acquisition of autoshaped lever responding and with more reliable failure to increase lever responding in the latent inhibition paradigm. Thus, increasing food deprivation was associated with enhanced acquisition regardless of whether the required performance was an increase or a failure to increase the same behavior, indicating a specific effect on learning.

  2. Effects of Haloperidol on Responding Maintained with Food and Sucrose-Water

    Directory of Open Access Journals (Sweden)

    Carlos F. Aparicio

    2010-02-01

    Full Text Available The “hedonic” value of reinforcers is mediated by dopamine. Accordingly,haloperidol diminishes the value of reinforcers, by interfering with the emission of operant behaviors. Alternatively, the interference of dopamine transmission does not prevent animals from eating food. Thus, reinforcers remain intact after the administration of haloperidol. We assessed these possibilities with eight Wistar rats and two types of reinforcers, food-pellets and sucrose-water, delivered under multiple reinforcement schedules. Ingeneral, lever presses maintained by food-pellets were higher than those maintained by sucrose-water. Haloperidol produced dose-related decreases in lever presses and obtained reinforcers. Different doses had no effect on the number of lever presses. Subcutaneous administrations of haloperidol produced higher decreases in lever presses than intra-peritoneal administrations. Decreases in lever pressing were not necessarily accompanied by substantial reductions in obtained food-pellets and sucrose-water reinforcers; underthe effects of haloperidol rats continued to produce a considerable number of both types of reinforcers.

  3. A coal combine

    Energy Technology Data Exchange (ETDEWEB)

    Wlachovsky, I; Bartos, J

    1980-02-15

    A design is presented for a coal combine, equipped with two drum operational units, on whose both ends of the upper surface of the body, two coal saws are mounted with the help of a lever system. These saws, found in an operational position, form a gap in the block of the coal block, which is not embraced by the drum operational unit. The coal block, found between the gap and the support, falls down onto the longwall scraper conveyor. The lever system of each coal saw is controlled by two hydraulic jacks. One of the jacks is mounted vertically on the facial wall of the body of the combine and is used for the hoisting for the required height of the horizontal arm of the lever, reinforced by one end in the hinge on the body of the combine. On the ''free'' end of that lever, a coal saw is mounted in a hinge-like fashion and which is connected by the hydraulic jack to the horizontal arm of the lever system. This hydraulic jack is used for the clamping of the coal saw to the face.

    2017-02-14

    An exemplary mounting clip for removably attaching panels to a supporting structure comprises a base, spring locking clips, a lateral flange, a lever flange, and a spring bonding pad. The spring locking clips extend upwardly from the base. The lateral flange extends upwardly from a first side of the base. The lateral flange comprises a slot having an opening configured to receive at least a portion of one of the one or more panels. The lever flange extends outwardly from the lateral flange. The spring bonding flange extends downwardly from the lever flange. At least a portion of the first spring bonding flange comprises a serrated edge for gouging at least a portion of the one or more panels when the one or more panels are attached to the mounting clip to electrically and mechanically couple the one or more panels to the mounting clip.

  5. Nucleus accumbens opioid, GABaergic, and dopaminergic modulation of palatable food motivation: contrasting effects revealed by a progressive ratio study in the rat.

    Zhang, Min; Balmadrid, Christian; Kelley, Ann E

    2003-04-01

    The current studies were designed to evaluate whether incentive motivation for palatable food is altered after manipulations of opioid, GABAergic, and dopaminergic transmission within the nucleus accumbens. A progressive ratio schedule was used to measure lever-pressing for sugar pellets after microinfusion of drugs into the nucleus accumbens in non-food-deprived rats. The mu opioid agonist D-Ala2, NMe-Phe4, Glyo15-enkephalin and the indirect dopamine agonist amphetamine induced a marked increase in break point and correct lever-presses; the GABA(A) agonist muscimol did not affect breakpoint or lever-presses. The data suggest that opioid, dopaminergic, and GABAergic systems within the accumbens differentially modulate food-seeking behavior through mechanisms related to hedonic evaluation of food, incentive salience, and control of motor feeding circuits, respectively.

  6. Digitization and the open management of data: New prospects for electricity distributors

    International Nuclear Information System (INIS)

    Derdevet, Michel

    2017-01-01

    At the core of both the energy transition and the digital revolution are the grids for distributing electricity during this era of big data. The electricity grid is becoming smarter and smarter, as it is equipped with sensors capable of providing information and data - the leading example being the 35 million smart electricity meters to be installed in French households by 2021. Backed by recent legislation, the trend toward open data is, for distributors, both a requirement and a lever: an economic, social and environmental requirement for enabling localities to prove their sense of responsibility and for developing innovative services for citizens; but also a lever for distributors to become operators who, processing dynamic data, are open to their ecosystem - a lever for making new business models emerge for the local management of energy

    2004-01-01

    Because of its ultrahigh sensitivity, the optical lever detection method similar to that used in the atomic force microscope (AFM) has been widely employed as a standard technique for measuring microcantilever deflection. Along with the increasing interest in using the microcantilever as a sensing platform, there is also a requirement for a reliable calibration technique. Many researchers have used the concept of optical lever detection to construct microcantilever deflection readout instruments for chemical, physical, and biological detection. However, without an AFM piezo z scanner, it is very difficult to precisely calibrate these instruments. Here, we present a step-by-step method to conveniently calibrate an instrument using commercially available piezoresistive cantilevers. The experimental results closely match the theoretical calculation. Following this procedure, one can easily calibrate any optical cantilever deflection detection system with high reproducibility, precision, and reliability. A detailed discussion of the optical lever readout system design has been addressed in this article

  9. Blockade of muscarinic receptors impairs the retrieval of well-trained memory

    Directory of Open Access Journals (Sweden)

    Shogo eSoma

    2014-04-01

    Full Text Available Acetylcholine (ACh is known to play an important role in memory functions, and its deficit has been proposed to cause the cognitive decline associated with advanced age and Alzheimer’s disease (the cholinergic hypothesis. Although many studies have tested the cholinergic hypothesis for recently acquired memory, only a few have investigated the role of ACh in the retrieval process of well-trained cognitive memory, which describes the memory established from repetition and daily routine. To examine this point, we trained rats to perform a two-alternative forced-choice visual detection task. Each trial was started by having the rats pull upward a central-lever, which triggered the presentation of a visual stimulus to the right or left side of the display monitor, and then pulling upward a stimulus-relevant choice-lever located on both sides. Rats learned the task within 10 days, and the task training was continued for a month. Task performance was measured with or without systemic administration of a muscarinic ACh receptor (mAChR antagonist, scopolamine (SCOP, prior to the test. After 30 min of SCOP administration, rats stopped manipulating any lever even though they explored the lever and surrounding environment, suggesting a loss of the task-related associative memory. Three hours later, rats were recovered to complete the trial, but the rats selected the levers irrespective of the visual stimulus, suggesting they remembered a series of lever-manipulations in association with a reward, but not association between the reward and visual stimulation. Furthermore, an m1-AChR, but not nicotinic AChR antagonist caused a similar deficit in the task execution. SCOP neither interfered with locomotor activity nor drinking behavior, while it influenced anxiety. These results suggest that the activation of mAChRs at basal ACh levels is essential for the recall of well-trained cognitive memory.

    Effects of experience with Pavlovian autoshaping procedures on lever-press autoshaping conditioned response (CR) performance and 3H-8-OH-DPAT-labeled binding of 5-HT(1a) receptors as well as 125I-LSD-labeled binding of 5-HT(2a) receptors were evaluated in four groups of male Long-Evans hooded rats. Two groups of rats (Group Paired High CR and Group Paired Low CR) received Pavlovian autoshaping procedures wherein the presentation of a lever (conditioned stimulus, CS) was followed by the response-independent presentation of food (unconditioned stimulus, US). Rats in Group Paired High CR (n=12) showed more rapid CR acquisition and higher asymptotic levels of lever-press autoshaping CR performance relative to rats in Group Low CR (n=12). Group Omission (n=9) received autoshaping with an omission contingency, such that performing the lever-press autoshaping CR resulted in the cancellation the food US, while Group Random (n=9) received presentations of lever CS and food US randomly with respect to one another. Though Groups Omission and Random did not differ in lever-press autoshaping CR performance, Group Omission showed significantly lower levels of 3H-8-OH-DPAT-labeled 5-HT(1a) binding in post-synaptic areas (frontal cortex, septum, caudate putamen), as well as significantly higher plasma corticosterone levels than Group Random. In addition, Group Random showed higher levels of 3H-8-OH-DPAT-labeled 5-HT(1a) binding in pre-synaptic somatodendritic autoreceptors on dorsal raphe nucleus relative to each of the other three groups. Autoradiographic analysis of 125I-LSD-labeled 5-HT(2a) receptor binding revealed no significant differences between Groups Paired High CR and Paired Low CR or between Groups Omission and Random in any brain regions.

    Highlights: • Design of a lever type creep machine for carrying out creep test in flowing sodium. • Leveling of lever during creep was achieved by automated movement of fulcrum. • Design of creep chamber for providing constant sodium flow rate across creep specimen. • Minimum use of bellow in chamber for sodium containment and mechanical isolation. • Mini-lever mechanism to counter balance load reduction on specimen due to bellow stiffness. - Abstract: A creep testing system has been designed, fabricated, installed and validated for carrying out creep tests in flowing liquid sodium. The testing system consists of two sections namely creep testing machine and an environmental chamber. The testing system has the ability of (i) applying tensile load to the test specimen through a lever, (ii) monitoring continuously the creep elongation and (iii) allowing sodium to flow around the creep specimen at constant velocity. The annular space between the creep specimen and the environmental chamber has been suitably designed to maintain constant sodium flow velocity. Primary and secondary bellows are employed in the environmental chamber to (i) mechanically isolate the creep specimen, (ii) prevent the flowing sodium in contact with air and (iii) maintain an argon gas cover to the leaking sodium if any from primary bellow, with a provision to an alarm get activated by a spark plug. The lever-horizontality during creep test has been maintained by automatically lifting up the fulcrum instead of lowering down the pull rod as conventionally used. A mini lever mechanism has been incorporated in the load train to counter balance the load reduction on specimen from the changing stiffness of the bellows. The validation of the testing system has been established by carrying out creep tests on 316L(N) stainless steel at 873 K over a wide stress range and comparing the results with those obtained in air by employing the developed and conventional creep testing machines.

    Clinical studies have shown that patients with exaggerated risk-taking tendencies have high baseline levels of norepinephrine. In this work, we systemically manipulated norepinephrine levels in rats and studied their behavioral changes in a probabilistic discounting task, which is a paradigm for gauging risk taking. This study aims to explore the effects of the selective norepinephrine reuptake inhibitor (atomoxetine at doses of 0.6, 1.0 and 1.8 mg/kg), and receptor selective antagonists (propranolol at a single dose of 1.0/kg, and prazosin at a single dose of 0.1 mg/kg), on risk taking using a probabilistic discounting task. In this task, there were two levers available to rats: pressing the 'small/certain' lever guaranteed a single food pellet, and pressing the 'large/risky' lever yielded either four pellets or none. The probability of receiving four food pellets decreased across the four experimental blocks from 100% to 12.5%. Atomoxetine increased the tendency to choose the large/risky lever. It significantly reduced the lose-shift effect (i.e. pressing a different lever after losing a trial), but did not affect the win-stay effect (i.e. pressing the same lever after winning a trial). Furthermore, co-administration of beta-adrenoreceptor antagonist, propranolol, eliminated the effects of atomoxetine on risk taking and the lose-shift effect; but co-administration of alpha1-adrenoreceptor antagonist, prazosin, did not. Atomoxetine boosted NE levels and increased risk taking. This was because atomoxetine decreased rats' sensitivity to losses. These effects were likely mediated by beta-adrenoreceptor.

    Rationale Cannabinoid antagonists purportedly have greater effects in reducing the intake of highly palatable food compared to less palatable food. However, this assertion is based on free-feeding studies in which the amount of palatable food eaten under baseline conditions is often confounded with other variables, such as unequal access to both food options and differences in qualitative features of the foods. Objective We attempted to reduce these confounds by using a model of choice that programmed the delivery rates of sucrose and carrot-flavored pellets. Methods Lever-pressing of ten lean (Fa/Fa or Fa/fa) and ten obese (fa/fa) Zucker rats was placed under three conditions in which programmed ratios for food pellets on two levers were 5:1, 1:1, and 1:5. In Phase 1, responses on the two levers produced one type of pellet (sucrose or carrot); in Phase 2, responses on one lever produced sucrose pellets and on the other lever produced carrot pellets. After responses stabilized under each food ratio, acute doses of rimonabant (0, 3, and 10 mg/kg) were administered before experimental sessions. The number of reinforcers and responses earned per session under each ratio and from each lever was compared. Results and Conclusions Rimonabant reduced reinforcers in 1:5 and 5:1 food ratios in Phase 1, and across all ratios in Phase 2. Rimonabant reduced sucrose and carrot-flavored pellet consumption similarly; rimonabant did not affect bias toward sucrose, but increased sensitivity to amount differences in lean rats. This suggests that relative amount of food, not palatability, may be an important behavioral mechanism in the effects of rimonabant. PMID:24398820

    In this protocol, social motivation is measured in mice through a pair of operant conditioning paradigms. To conduct the experiments, two-chambered shuttle boxes were equipped with two operant levers (left and right) and a food receptacle in one chamber, which was then divided from the second chamber by an automated guillotine door covered by a wire grid. Different stimulus mice, rotated across testing days, served as a social stimulus behind the wire grid, and were only visible following the opening of the guillotine door. Test mice were trained to lever press in order to open the door and gain access to the stimulus partner for 15 sec. The number of lever presses required to obtain the social reward progressively increased on a fixed schedule of 3. Testing sessions ended after test mice stopped lever pressing for 5 consecutive minutes. The last reinforced ratio or breakpoint can be used as a quantitative measure of social motivation. For the second paradigm, test mice were trained to discriminate between left and right lever presses in order to obtain either a food reward or the social reward. Mice were rewarded for every 3 presses of each respective lever. The number of food and social rewards can be compared as a measurement of the value placed upon each reward. The ratio of each reward type can also be compared between mouse strains and the change in this ratio can be monitored within testing sessions to measure satiation with a given reward type. Both of these operant conditioning paradigms are highly useful for the quantification of social motivation in mouse models of autism and other disorders of social behavior.

    It was shown recently that the Force Feedback Microscope (FFM) can avoid the jump-to-contact in Atomic force Microscopy even when the cantilevers used are very soft, thus increasing force resolution. In this letter, we explore theoretical aspects of the associated real time control of the tip position. We take into account lever parameters such as the lever characteristics in its environment, spring constant, mass, dissipation coefficient, and the operating conditions such as controller gains and interaction force. We show how the controller parameters are determined so that the FFM functions at its best and estimate the bandwidth of the system under these conditions.

    1987-01-01

    Operating turbine stopped smoothly by fail-safe mechanism. Windturbine braking systems improved by system consisting of two large steel-alloy disks mounted on high-speed shaft of gear box, and brakepad assembly mounted on bracket fastened to top of gear box. Lever arms (with brake pads) actuated by spring-powered, pneumatic cylinders connected to these arms. Springs give specific spring-loading constant and exert predetermined load onto brake pads through lever arms. Pneumatic cylinders actuated positively to compress springs and disengage brake pads from disks. During power failure, brakes automatically lock onto disks, producing highly reliable, fail-safe stops. System doubles as stopping brake and "parking" brake.

    A spider elevator is proposed which contains a body, a wedge clamp with wedges hinged to each other, a subassembly for holding the wedge clamp in the open and closed positions and a mechanism for changing the wedge clamp, which is made in the form of levers with ears for cleats and installed in the body with the capability of turning. To increase reliability in the operational mode through using the external force for clamping the pipe, the free ends of the levers are hinged with the body by a power cylinder.

    An elevator is proposed which includes a body, a flap, a lock with a catch and a spring-loaded shut-off clamp in the form of upper and lower horizontal levers which are connected by a handle and an axle and one end of which is made in the form of an eccentric cam. The size of the eccentricity of the cam of the levers is increased toward the handle of the clamp in order to increase the operational reliability and to extend the service life.

    The research Sustainable Urban Infrastructure conducted by McKinsey and Company and Siemens assesses technological levers of varying effectiveness, and with different cost implications, which can all contribute to greater environmental sustainability in cities, drawing in particular on the example of London. It's the first comprehensive research focusing on technological and economic implications of a city's infrastructure management in the fields of energy, buildings and transportation. The encouraging message is that many of the levers to reduce energy consumption and CO2 emissions in urban agglomerations not only help protect the environment, but also pay back from an economic point of view.

    The purpose of this study was to present a literature review about photoelasticity, a laboratory method for evaluation of implants prosthesis behavior. Fixed or removable prostheses function as levers on supporting teeth, allowing forces to cause tooth movement if not carefully planned. Hence, during treatment planning, the dentist must be aware of the biomechanics involved and prevent movement of supporting teeth, decreasing lever-type forces generated by these prosthesis. Photoelastic analysis has great applicability in restorative dentistry as it allows prediction and minimization of biomechanical critical points through modifications in treatment planning.

  6. From experimental zoology to big data: Observation and integration in the study of animal development.

    2015-06-01

    The founding of the Journal of Experimental Zoology in 1904 was inspired by a widespread turn toward experimental biology in the 19th century. The founding editors sought to promote experimental, laboratory-based approaches, particularly in developmental biology. This agenda raised key practical and epistemological questions about how and where to study development: Does the environment matter? How do we know that a cell or embryo isolated to facilitate observation reveals normal developmental processes? How can we integrate descriptive and experimental data? R.G. Harrison, the journal's first editor, grappled with these questions in justifying his use of cell culture to study neural patterning. Others confronted them in different contexts: for example, F.B. Sumner insisted on the primacy of fieldwork in his studies on adaptation, but also performed breeding experiments using wild-collected animals. The work of Harrison, Sumner, and other early contributors exemplified both the power of new techniques, and the meticulous explanation of practice and epistemology that was marshaled to promote experimental approaches. A century later, experimentation is widely viewed as the standard way to study development; yet at the same time, cutting-edge "big data" projects are essentially descriptive, closer to natural history than to the approaches championed by Harrison et al. Thus, the original questions about how and where we can best learn about development are still with us. Examining their history can inform current efforts to incorporate data from experiment and description, lab and field, and a broad range of organisms and disciplines, into an integrated understanding of animal development. © 2015 Wiley Periodicals, Inc.

  9. Moment stability for a predator–prey model with parametric dichotomous noises

    2015-01-01

    In this paper, we investigate the solution moment stability for a Harrison-type predator–prey model with parametric dichotomous noises. Using the Shapiro–Loginov formula, the equations for the first-order and second-order moments are obtained and the corresponding stable conditions are given. It is found that the solution moment stability depends on the noise intensity and correlation time of noise. The first-order and second-order moments become unstable with the decrease of correlation time. That is, the dichotomous noise can improve the solution moment stability with respect to Gaussian white noise. Finally, some numerical results are presented to verify the theoretical analyses.

    The WKBJ method is applied to the third order for obtaining the eigenvalues for the fifth potential of Varshni, and the relevant integrals are analytically evaluated. Numerical results are obtained for the Lennard-Jones Potential, which is a special case of the Varshni V potential, and are compared to the results of Harrison and Bernstein obtained by a numerical integration of the wave equation. Error estimates are made. It is shown that for diatomic potentials, the Langer correction is not needed if the WKBJ approximation is carried to second and higher orders. (author)

    Full Text Available The paper is an attempt at a systematic account of the history of influences between anthropology and the theory of drama in the twentieth century. The starting point is the definition of drama as a mimesis of the movement towards self-knowledge as rebirth. It is described as a variation of the original spring dance in honour of the regeneration of life represented in the figure of the twice-born Dionysus. Anthropologists whose contribution to the theory of drama has been acknowledged are Jane Harrison, Gilbert Murray, Arnold Van Genep, Joseph Campbell and Victor Turner.

    The authors have demonstrated that baboons can be immunized with S. haemotobium schistosomula irradiated with 20 krad in a regimen that induces 90% protection. While this high level of protection has stimulated a discussion on the feasibility of a human volunteer trial (Von Lichtenberg, 1985), results of further studies particularly on (i) the pathogensis of immunization per se (Byram et al., 1989), (ii) the longevity of protection, and (iii) the protective efficacy of cryopreserved irradiated S. haemotobium schistosomula (R.
