  4. A historical overview of probabilistic risk assessment development and its use in the nuclear power industry: a tribute to the late Professor Norman Carl Rasmussen

    Keller, William; Modarres, Mohammad

    2005-01-01

    This paper reviews the historical development of the probabilistic risk assessment (PRA) methods and applications in the nuclear industry. A review of nuclear safety and regulatory developments in the early days of nuclear power in the United States has been presented. It is argued that due to technical difficulties for measuring and characterizing uncertainties and concerns over legal challenges, safety design and regulation of nuclear power plants has primarily relied upon conservative safety assessment methods derived based on a set of design and safety principles. Further, it is noted that the conservatism adopted in safety and design assessments has allowed the use of deterministic performance assessment methods. This approach worked successfully in the early years of nuclear power epoch as the reactor design proved to be safe enough. However, it has been observed that as the conservative approach to design and safety criteria proved arbitrary, and yielded inconsistencies in the degree to which different safety measures in nuclear power plants protect safety and public heath, the urge for a more consistent assessment of safety became apparent in the late 1960s. In the early 1970s, as a result of public and political pressures, then the US Atomic Energy Commission initiated a new look at the safety of the nuclear power plants through a comprehensive study called 'Reactor Safety Study' (WASH-1400, or 'Rasmussen Study'-after its charismatic study leader Professor Norman Rasmussen of MIT) to demonstrate safety of the nuclear power plants. Completed in October 1975, this landmark study introduced a novel probabilistic, systematic and holistic approach to the assessment of safety, which ultimately resulted in a sweeping paradigm shift in safety design and regulation of nuclear power in the United States in the turn of the Century. Technical issues of historic significance and concerns raised by the subsequent reviews of the Rasmussen Study have been discussed

  8. Magnus air turbine system

    Science.gov (United States)

    Hanson, Thomas F.

    1982-01-01

    A Magnus effect windmill for generating electrical power is disclosed. A large nacelle-hub mounted pivotally (in Azimuth) atop a support tower carries, in the example disclosed, three elongated barrels arranged in a vertical plane and extending symmetrically radially outwardly from the nacelle. The system provides spin energy to the barrels by internal mechanical coupling in the proper sense to cause, in reaction to an incident wind, a rotational torque of a predetermined sense on the hub. The rotating hub carries a set of power take-off rollers which ride on a stationary circular track in the nacelle. Shafts carry the power, given to the rollers by the wind driven hub, to a central collector or accumulator gear assembly whose output is divided to drive the spin mechanism for the Magnus barrels and the main electric generator. A planetary gear assembly is interposed between the collector gears and the spin mechanism functioning as a differential which is also connected to an auxiliary electric motor whereby power to the spin mechanism may selectively be provided by the motor. Generally, the motor provides initial spin to the barrels for start-up after which the motor is braked and the spin mechanism is driven as though by a fixed ratio coupling from the rotor hub. During high wind or other unusual conditions, the auxiliary motor may be unbraked and excess spin power may be used to operate the motor as a generator of additional electrical output. Interposed between the collector gears of the rotating hub and the main electric generator is a novel variable speed drive-fly wheel system which is driven by the variable speed of the wind driven rotor and which, in turn, drives the main electric generator at constant angular speed. Reference is made to the complete specification for disclosure of other novel aspects of the system such as, for example, the aerodynamic and structural aspects of the novel Magnus barrels as well as novel gearing and other power coupling

    1983-01-01

    Magnus forces and moments were measured on a basic-finner model spinning in transonic flow. Spin was induced by canted fins or by full-span or semi-span, outboard and inboard roll controls. Magnus force and moment reversals were caused by Mach number, reduced spin rate, and angle of attack variations. Magnus center of pressure was found to be independent of the angle of attack but varied with the Mach number and model configuration or reduced spin rate.

    Oscillations between active and sterile neutrinos remain as an open possibility to explain some anomalous experimental observations. In a four-neutrino (three active plus one sterile) mixing scheme, we use the Magnus expansion of the evolution operator to study the evolution of neutrino flavor amplitudes within the Earth. We apply this formalism to calculate the transition probabilities from active to sterile neutrinos with energies of the order of a few GeV, taking into account the matter effect for a varying terrestrial density.

    Full Text Available Following a short introduction on medical photography and cinematography, we describe a recently discovered neurological film collection, the so called Magnus-Rademaker collection (1909-1940, earlier presumed to be lost. Rudolf Magnus was professor in pharmacology in Utrecht and Gysbertus Rademaker was professor in physiology and later in neurology in Leiden. At the time they performed experimental research on animals to the role of the labyrinth, the neck afferents and cerebellum in position and standing. Next to animals, they also filmed patients. As an example we discuss a film about a boy whose cerebellum had been largely removed because of a tumor. The case was discussed for the ‘Amsterdam Neurologists Society’ and reported upon in the Dutch journal of medicine (1940. The films were produced for educational, as well as for scientific purposes. the discovery of this collection contributes to a better understanding of the role that early cinematography played in science and medicine.

    Time-dependent perturbation theory as a tool to compute approximate solutions of the Schroedinger equation does not preserve unitarity. Here we present, in a simple way, how the Magnus expansion (also known as exponential perturbation theory) provides such unitary approximate solutions. The purpose is to illustrate the importance and consequences of such a property. We suggest that the Magnus expansion may be introduced to students in advanced courses of quantum mechanics.

    The effect of the Magnus force in optical micromanipulation has been observed. An ad hoc experiment has been designed based on a one-dimensional optical trap that carries angular momentum. The observed particle dynamics reveals the occurrence of this hydrodynamic force, which is neglected in the common approach. Its measured value is larger than the one predicted by the existing theoretical models for micrometric particles and low Reynolds number, showing that the Magnus force can contribute to unconventional optohydrodynamic trapping and manipulation.

    We perform systematic Langevin molecular dynamics simulations of interacting skyrmions in thin films. The interplay between the Magnus force, the repulsive skyrmion-skyrmion interaction, and the thermal noise yields different regimes during nonequilibrium relaxation. In the noise-dominated regime, the Magnus force enhances the disordering effects of the thermal noise. In the Magnus-force-dominated regime, the Magnus force cooperates with the skyrmion-skyrmion interaction to yield a dynamic regime with slow decaying correlations. These two regimes are characterized by different values of the aging exponent. In general, the Magnus force accelerates the approach to the steady state.

    1991-01-01

    A simple approximate nonperturbative method is described for treating time-dependent problems that works well in the intermediate regime far from both the sudden and the adiabatic limits. The method consists of applying the Magnus expansion after transforming to the adiabatic basis defined by the eigenstates of the instantaneous Hamiltonian. A few exactly soluble examples are considered in order to assess the domain of validity of the approximation. (author) 32 refs., 4 figs

    Historical films made by neuroscientists have shown up in several countries during past years. Although originally supposed to have been lost, we recently found a collection of films produced between 1909 and 1940 by Rudolf Magnus (1873-1927), professor of pharmacology (Utrecht) and his student Gysbertus Rademaker (1887-1957), professor of physiology (1928, succeeding Willem Einthoven) and neurology (1945, both in Leiden). Both collections deal with the physiology of body posture by the equilibrium of reflex musculature contractions for which experimental studies were done with animals (labyrinthectomies, cerebellectomies, and brainstem sections) and observations on patients. The films demonstrate the results of these studies. Moreover, there are films with babies showing tonic neck reflexes and moving images capturing adults with cerebellar symptoms following cerebellectomies for tumors and several other conditions. Magnus' studies resulted in his well-known Körperstellung (1924, "Body Posture") and Rademaker's research in his Das Stehen (1931, "Standing"). The films probably had an educative and scientific purpose. Magnus demonstrated his films at congresses, including the Eighth International Congress of Physiologists (Vienna, 1910) and Rademaker screened his moving images at meetings of the Amsterdam Neurologists Society (at several occasions as reflected in the Winkler-Monakow correspondence and the Nederlands Tijdschrift voor Geneeskunde). Next to these purposes, the films were used to analyze movement and a series of images from the films were published in articles and books. The films are important historical sources that provide a portrait of the pre-World War II era in neuroscience, partly answering questions on how physicians dealt with patients and researchers with their laboratory animals. Moreover, the films confirm that cinematography was an important scientific tool in neuroscience research.

  8. Magnus force and Aharonov-Bohm effect in superfluids

    2002-01-01

    This chapter addresses the problem of the transverse force (Magnus force) on a vortex in a Galilean invariant quantum Bose liquid. Interaction of quasi-particles (phonons) with a vortex produces an additional transverse force (Iordanskii force). The Iordanskii force is related to the acoustic Aharonov-Bohm effect. The connection between the effective Magnus force and the Berry phase is also discussed. (orig.)

    Sonin, E.B.

    1997-01-01

    The forces on the vortex, transverse to its velocity, are considered. In addition to the superfluid Magnus force from the condensate (superfluid component), there are transverse forces from thermal quasiparticles and external fields violating the Galilean invariance. The forces between quasiparticles and the vortex originate from interference of quasiparticles with trajectories on the left and on the right from the vortex like similar forces for electrons interacting with the thin magnetic-flux tube (the Aharonov-Bohm effect). These forces are derived for phonons from the equations of superfluid hydrodynamics, and for BCS quasiparticles from the Bogolyubov endash de Gennes equations. The effect of external fields breaking Galilean invariance is analyzed for vortices in the two-dimensional Josephson junction array. The symmetry analysis of the classical equations for the array shows that the total transverse force on the vortex vanishes. Therefore the Hall effect which is linear in the transverse force is absent also. This means that the Magnus force from the superfluid component exactly cancels with the transverse force from the external fields. The results of other approaches are also brought together for discussion. copyright 1997 The American Physical Society

  11. Inverse Magnus force in free molecular flow

    Science.gov (United States)

    Herczynski, A.; Weidman, P.

    2003-11-01

    The sidewise force on a spinning sphere translating in a rarified gas is calculated assuming that the flow can be treated as a stream of free molecules. This approach was first introduced by Newton in his investigation of the drag force. While it is not fruitful at subsonic flows in normal conditions, it gives remarkably accurate results at hypersonic speeds. Here it is applied to the high Knudsen number flow over spinning spheres, cylinders, cubes and more generally any spinning parallelepiped. In all cases, the force is in the opposite direction to that of the classical Magnus effect in continuum flow. The simple calculation for a sphere reproduces the isothermal result obtained recently by Borg, et al. (Phys. Fluids, 15, 2003) using Maxwellian distribution functions. For any parallelepiped, including the cube, just like for the sphere and the cylinder, the force is shown to be steady. In each of these, the magnitude of the inverse Magnus force is proprtional to the product of the angular speed, translational speed, and the mas of the gas displaced by the object.

In this engine instead of traditional propellers the rotatable cylinders are installed. According interaction of the cylinders with wind the Magnus force arises. Magnus force exceeds propellers rise force in 5-10 times and maintain very large turning moment of wind wheel and most effective operation of engine, especially at low wind rates. Advantage of the engine consists in that it switch on under wind rate 1 m/c, when for propeller one requires 4-5 m/c

  16. Magnus forces and statistics in 2 + 1 dimensions

    International Nuclear Information System (INIS)

    Davis, R.L.

    1990-01-01

    Spinning vortex solutions to the abelian Higgs model, not Nielsen-Olesen solutions, are appropriate to a Ginzburg-Landau description of superconductivity. The main physical distinction is that spinning vortices experience the Magnus force while Nielsen-Olesen vortices do not. In 2 + 1 dimensional superconductivity without a Chern-Simons interaction, the effect of the Magnus force is equivalent to that of a background fictitious magnetic field. Moreover, the phase obtained an interchanging two quasi-particles is always path-dependent. When a Chern-Simons term is added there is an additional localized Magnus flux at the vortex. For point-like vortices, the Chern-Simons interaction can be seen as defining their intrinsic statistics, but in realistic cases of vortices with finite size in strong Magnus fields the quasi-particle statistics are not well-defined

  17. Magnus Effect on a Spinning Satellite in Low Earth Orbit

    Science.gov (United States)

    Ramjatan, Sahadeo; Fitz-Coy, Norman; Yew, Alvin Garwai

    2016-01-01

    A spinning body in a flow field generates an aerodynamic lift or Magnus effect that displaces the body in a direction normal to the freestream flow. Earth orbiting satellites with substantial body rotation in appreciable atmospheric densities may generate a Magnus force to perturb orbital dynamics. We investigate the feasibility of using this effect for spacecraft at a perigee of 80km using the Systems Tool Kit (STK). Results show that for a satellite of reasonable properties, the Magnus effect doubles the amount of time in orbit. Orbital decay was greatly mitigated for satellites spinning at 10000 and 15000RPM. This study demonstrates that the Magnus effect has the potential to sustain a spacecraft's orbit at a low perigee altitude and could also serve as an orbital maneuver capability.

His legacy spawned a line of Swedish and Danish mycologists intent on perpetuating the Fries tradition: Hampus von Post, Lars Romell, Seth Lundell and John Axel Nannfeldt in Sweden; Emil Rostrup, Severin Petersen and Jakob Lange in Denmark. Volumes of color paintings and several exsiccati, most notably one edited by Lundell and Nannfeldt attached fungal portraits and preserved specimens (and often photographs) to Fries names. The result is a massive resource from which to harvest the name-concept relationship with clarity. In the 20th century, nomenclatural commissions legislated Fries's Systema and Elenchus as the "starting point" for names of most fungi, giving these books special recognition. The present paper attempts to trace Fries's legacy from his lifetime to the recent past.

    One of the most bizarre and forgotten suggestions to have developed from the discussion of pauperism in the 19th century was the infibulation of the impoverished men. A communication in 1827 from the Halle professor of surgery, Carl August Weinhold (1782-1829), raised indignation and caused ironic as well as angry reactions. Despite such a heated response, Weinhold's proposed method of population control soon fell into oblivion, a fate considered by this contemporaries as "highly desirable".

    1988-12-01

    MAGNUS-3D is a professional finite element code for nonlinear magnetic engineering. MAGNUS-3D can solve numerically any general problem of linear or nonlinear magnetostatics in three dimensions. The problem is formulated in a domain with Dirichlet, Neumann or periodic boundary conditions, that can contain any combination of conductors of any shape in space, nonlinear magnetic materials with magnetic properties specified by magnetization tables, and nonlinear permanent magnets with any given demagnetization curve. MAGNUS-3D uses the two-scalar-potentials formulation of Magnetostatics and the finite element method, has an automatic 3D mesh generator, and advanced post-processing features that include graphics on a variety of supported devices, tabulation, and calculation of design quantities required in Magnetic Engineering. MAGNUS-3D is a general purpose 3D code, but it has been extensively used for accelerator work and many special features required for accelerator engineering have been incorporated into the code. One of such features is the calculation of field harmonic coefficients averaged in the direction of the beam, so important for the design of magnet ends. Another feature is its ability to calculate line integrals of any field component along the direction of the beam, or plot the field as a function of the z coordinate. MAGNUS-3D has found applications to the design of accelerator magnets and spectrometers, steering magnets, wigglers and undulators for free electron lasers, microtrons and magnets for synchrotron light sources, as well as magnets for NMR and medical applications, recording heads and various magnetic devices. There are three more programs closely associated with MAGNUS-3D. MAGNUS-GKS is the graphical postprocessor for the package; it supports a numer of output devices, including color vector or bit map devices. WIRE is an independent program that can calculate the field produced by any configuration of electric conductors in space, at any

  9. Role of transverse-momentum currents in the optical Magnus effect in free space

    2010-01-01

    We establish a general vector field model to describe the role of transverse-momentum currents in the optical Magnus effect in free space. As an analogy of the mechanical Magnus effect, the circularly polarized wave packet in our model acts as the rotating ball, and its rotation direction depends on the polarization state. Based on this model, we demonstrate the existence of an optical polarization-dependent Magnus effect which is significantly different from the conventional optical Magnus e...

  11. Magnus force in discrete and continuous two-dimensional superfluids

    International Nuclear Information System (INIS)

    Gecse, Z.; Khlebnikov, S.

    2005-01-01

    Motion of vortices in two-dimensional superfluids in the classical limit is studied by solving the Gross-Pitaevskii equation numerically on a uniform lattice. We find that, in the presence of a superflow directed along one of the main lattice periods, vortices move with the superflow on fine lattices but perpendicular to it on coarse ones. We interpret this result as a transition from the full Magnus force in a Galilean-invariant limit to vanishing effective Magnus force in a discrete system, in agreement with the existing experiments on vortex motion in Josephson junction arrays

    A Newton-inspired particle interaction model is introduced to compute the sideways force on spinning projectiles translating through a rarefied gas. The simple model reproduces the inverse Magnus force on a sphere reported by Borg, Söderholm and Essén [Phys. Fluids 15, 736 (2003)] using probability theory. Further analyses given for cylinders and parallelepipeds of rectangular and regular polygon section point to a universal law for this class of geometric shapes: when the inverse Magnus force is steady, it is proportional to one-half the mass M of gas displaced by the body.

Initially, the thesis that Schmitt’s theory works within two different levels, i.e., a conceptual one, which is essentially analytical, and a phenomenal one, which according to him would be descriptive only, is sustained. At this point, Schmitt’s theory of democracy and its critique of parliamentary democracy can be better understood. Finally, some criticisms against Schmitt’s position are presented.

    The Magnus effect is well-known for its influence on the flight path of a spinning ball. Besides ball games, the method of producing a lift force by spinning a body of revolution in cross-flow was not used in any kind of commercial application until the year 1924, when Anton Flettner invented and built the first rotor ship Buckau. This sailboat extracted its propulsive force from the airflow around two large rotating cylinders. It attracted attention wherever it was presented to the public and inspired scientists and engineers to use a rotating cylinder as a lifting device for aircraft. This article reviews the application of Magnus effect devices and concepts in aeronautics that have been investigated by various researchers and concludes with discussions on future challenges in their application.

  5. Three-dimensional magnetic engineering: The programs MAGNUS and EPILOG

    International Nuclear Information System (INIS)

    Fan Mingwu; Pissanetzky, S.

    1988-01-01

    We present the post-processor EPILOG for the well established finite element program MAGNUS for three-dimensional magnetic engineering. MAGNUS solves problems of magnetostastics with nonlinear magnetic materials, permanent magnets and electric currents, for any 3-D geometry. The two-scalar-potentials formulation of magnetostatics used by MAGNUS combines numerical accuracy and computational efficiency, and is considered state of the art. The well known program KUBIK is used as a pre-processor to describe the geometry and finite element mesh. KUBIK is highly interactive and allows the user to effectively control all geometric details. The needs of magnetic engineers, however, go far beyond the simple availability of a mathematical solution. Once the solution has been obtained by MAGNUS in the form of a continuous magnetic scalar potential function defined at every point in the solution domain, those needs are met by EPILOG. EPILOG is command operated. Commands are independent of each other and can be used in any order, or not used at all. The purpose of each command is to use the solution for the calculation of a derived quantity or the production of a plot or table. The following derived quantities can be obtained: The magnetic energy in specific regions, the magnetic force on specified conductors in space, the magnetic torque in specified conductors, the magnetic flux across a given surface in space, the inductance of a circuit, and a variety of line integrals for specified lines in space. A useful facility is the automatic calculation of harmonic multipoles averaged along the beam direction for accelerator magnets, essential for end analysis and the integral effect of the magnetic field on the beam.

  10. 3D accelerator magnet calculations using MAGNUS-3D

    International Nuclear Information System (INIS)

    Pissanetzky, S.; Miao, Y.

    1989-01-01

    The steady trend towards increased magnetic and geometric complexity in the design of accelerator magnets has caused a need for reliable 3D computer models and a better understanding of the behavior of magnetic system in three dimensions. The capabilities of the MAGNUS-3D family of programs are ideally suited to solve this class of problems and provide insight into 3D effects. MAGNUS-3D can solve any problem of magnetostatics involving permanent magnets, nonlinear ferromagnetic materials and electric conductors. MAGNUS-3D uses the finite element method and the two-scalar-potentials formulation of Maxwell's equations to obtain the solution, which can then be used interactively to obtain tables of field components at specific points or lines, plots of field lines, function graphs representing a field component plotted against a coordinate along any line in space (such as the beam line), and views of the conductors, the mesh and the magnetic bodies. The magnetic quantities that can be calculated include the force or torque on conductors or magnetic parts, the energy, the flux through a specified surface, line integrals of any field component along any line in space, and the average field or potential harmonic coefficients. We describe the programs with emphasis placed on their use for accelerator magnet design, and present an advanced example of actual calculations. (orig.)

Flow-field visualization aided in describing a flow model that divides the Magnus phenomenon into a subcritical region, where reverse Magnus loads are experienced, and a supercritical region where these loads are not encountered. The roles of the spin rate, angle of attack, and crossflow Reynolds number in determining the boundaries of the subcritical region and the variations of the Magnus loads were studied.

    This biography summarizes the seminal contributions to auroral and space science of Carl Størmer (1874 - 1957). He was the first to develop precise photographic methods to calculate heights and morphologies of diverse auroral forms during four solar cycles. Størmer independently devised numerical techniques to determine the trajectories of high-energy charged particles allowed and forbidden in the Earth’s magnetic field. His theoretical analyses explained cosmic ray access to the upper atmosphere, 20 years before they were identified by other scientists. Størmer’s crowning achievement, “The Polar Aurora,” published when he was 81 years old, stands to this day as a regularly cited guide in graduate-level courses on space physics.   The authors present the life of this prodigious scientist in relation to the cultural life of early 20th century in Norway and to the development of the space sciences in the post-Sputnik era.

    The formalism of Rodrigues-Hamilton parameters is applied to the Magnus problem related to the systematic drift of a gimbal-mounted astatic gyroscope due to the nutational vibration of the main axis of the rotor. It is shown that the use of the above formalism makes it possible to limit the analysis to a consideration of a linear system of differential equations written in perturbed values of Rodrigues-Hamilton parameters. A refined formula for the drift of the main axis of the gyroscope rotor is obtained, and an estimation is made of the effect of the truncation of higher-order terms.

    Two kinds of methods of explaining the physical mechanism of the Magnus effect are compared with each other and fully discussed. The first method uses Bernoulli's theorem and the fluid velocity difference between both sides of the body. The second one is based on the momentum theorem which relates the lift force with the fluid acceleration perpendicular to the uniform flow direction, which is caused by the asymmetry of separation points. It is shown that the latter method is preferable because it can be strictly applied to the real flow field containing both the rotational and the irrotational flow regions.

    Toon, Owen B.; Condon, Estelle P. (Technical Monitor)

    1997-01-01

    Inspired by childhood readings of books by Edgar Rice Burroughs, Carl Sagan's first interest in planetary science focused on Mars and Venus. Typical of much of his career he was skeptical of early views about these planets. Early in this century it was thought that the Martian wave of darkening, a seasonal albedo change on the planet, was biological in origin. He suggested instead that it was due to massive dust storms, as was later shown to be the case. He was the first to recognize that Mars has huge topography gradients across its surface. During the spacecraft era, as ancient river valleys were found on the planet, he directed studies of Mars' ancient climate. He suggested that changes in the planets orbit were involved in climate shifts on Mars, just as they are on Earth. Carl had an early interest in Venus. Contradictory observations led to a controversy about the surface temperature, and Carl was one of the first to recognize that Venus has a massive greenhouse effect at work warming its surface. His work on radiative transfer led to an algorithm that was extensively used by modelers of the Earth's climate and whose derivatives still dominate the calculation of radiative transfer in planetary atmospheres today. Carl inspired a vast number of young scientists through his enthusiasm for new ideas and discoveries, his skeptical approach, and his boundless energy. I had the privilege to work in Carl's laboratory during the peak of the era of Mars' initial exploration. It was an exciting time, and place. Carl made it a wonderful experience.

  5. Drift of suspended ferromagnetic particles due to the Magnus effect

    Denisov, S. I.; Pedchenko, B. O.

    2017-01-01

    A minimal system of equations is introduced and applied to study the drift motion of ferromagnetic particles suspended in a viscous fluid and subjected to a time-periodic driving force and a nonuniformly rotating magnetic field. It is demonstrated that the synchronized translational and rotational oscillations of these particles are accompanied by their drift in a preferred direction, which occurs under the action of the Magnus force. We calculate both analytically and numerically the drift velocity of particles characterized by single-domain cores and nonmagnetic shells and show that there are two types of drift, unidirectional and bidirectional, which can be realized in suspensions composed of particles with different core-shell ratios. The possibility of using the phenomenon of bidirectional drift for the separation of core-shell particles in suspensions is also discussed.

  6. Vacancy-rearrangement theory in the first Magnus approximation

    International Nuclear Information System (INIS)

    Becker, R.L.

    1984-01-01

    In the present paper we employ the first Magnus approximation (M1A), a unitarized Born approximation, in semiclassical collision theory. We have found previously that the M1A gives a substantial improvement over the first Born approximation (B1A) and can give a good approximation to a full coupled channels calculation of the mean L-shell vacancy probability per electron, p/sub L/, when the L-vacancies are accompanied by a K-shell vacancy (p/sub L/ is obtained experimentally from measurements of K/sub α/-satellite intensities). For sufficiently strong projectile-electron interactions (sufficiently large Z/sub p/ or small v) the M1A ceases to reproduce the coupled channels results, but it is accurate over a much wider range of Z/sub p/ and v than the B1A. 27 references

  7. Three-dimensional magnetic engineering: The programs magnus and epilog

    Science.gov (United States)

    Fan, Mingwu; Pissanetzky, Sergio

    1988-10-01

    We present the post-processor EPILOG for the well established finite element program MAGNUS for three-dimensional magnetic engineering. MAGNUS solves problems of magnetostatics with nonlinear magnetic materials, permanent magnets and electric currents, for any 3-D geometry. The two-scalar-potentials formulation of magnetostatics used by MAGNUS combines numerical accuracy and computational efficiency, and is considered state of the art. The well known program KUBIK is used as a pre-processor to describe the geometry and finite element mesh. KUBIK is highly interactive and allows the user to effectively control all geometric details. The needs of magnetic engineers, however, go far beyond the simple availability of a mathematical solution. Once the solution has been obtained by MAGNUS in the form of a continuous magnetic scalar potential function defined at every point in the solution domain, those needs are met by EPILOG. EPILOG is command operated. Commands are independent of each other and can be used in any order, or not used at all. The purpose of each command is to use the solution for the calculation of a derived quantity or the production of a plot or table. The following derived quantities can be obtained: the magnetic energy in specific regions, the magnetic force on specified conductors in space, the magnetic torque on specified conductors, the magnetic flux across a given surface in space, the inductance of a circuit, and a variety of line integrals for specified lines in space. A useful facility is the automatic calculation of harmonic multipoles averaged along the beam direction for accelerator magnets, essential for end analysis and the integral effect of the magnetic field on the beam. Graphical facilities include color plots of the shapes of the conductors, the geometry, field lines and surfaces of constant magnetic scalar potential in specified regions of space. EPILOG produces a device independent graphical metafile, which can be seen on any device

  4. Role of transverse-momentum currents in the optical Magnus effect in free space

    International Nuclear Information System (INIS)

    2010-01-01

    We establish a general vector field model to describe the role of transverse-momentum currents in the optical Magnus effect in free space. As an analogy of the mechanical Magnus effect, the circularly polarized wave packet in our model acts as the rotating ball, and its rotation direction depends on the polarization state. Based on this model, we demonstrate the existence of an optical polarization-dependent Magnus effect which is significantly different from the conventional optical Magnus effect in that light-matter interaction is not required. Further, we reveal the relation between transverse-momentum currents and the optical Magnus effect, and find that such a polarization-dependent rotation is unavoidable when the wave packet possesses transverse-momentum currents. The physics underlying this intriguing effect is the combined contributions of transverse spin and orbital currents. We predict that this effect may be observed experimentally even in the propagation direction. These findings provide further evidence for the optical Magnus effect in free space and can be extrapolated to other physical systems.

  10. Manlighet, mod och moral: Amanda Kerfstedts Carl Bergs skoltid

    Directory of Open Access Journals (Sweden)

    Andersson, Maria

    2011-03-01

    Full Text Available Amanda Kerfstedt’s ”Carl Bergs skoltid” describes a boy’s journey to manhood in late 19th century Sweden. This article pertains that the text contrasts an ideal of masculinity based on physical strength with an ideal emphasizing morality. Although a true man, as described in the story, is expected to be strong as well as righteous, the moral component is the most important. The text shows that courage and force, which are not checked by a sense of ethics, may turn into brutality and abuse of power. Different types of masculinity are compared in ”Carl Bergs skoltid” but masculinity is also defined in relation to ideas about femininity. The association with women is utilized to stress a lack of courage in men as well as to redefine a masculine ideal that has focused too much on physical prowess instead of strength of character.

    A baseline habitat evaluation procedures (HEP) analysis was conducted on the Carl property (160 acres) in June 2007 to determine the number of habitat units to credit Bonneville Power Administration (BPA) for providing funds to acquire the property as partial mitigation for habitat losses associated with construction of McNary Dam. HEP surveys also helped assess the general ecological condition of the property. The Carl property appeared damaged from livestock grazing and exhibited a high percentage of invasive forbs. Exotic grasses, while present, did not comprise a large percentage of the available cover in most areas. Cover types were primarily grassland/shrubsteppe with a limited emergent vegetation component. Baseline HEP surveys generated 356.11 HUs or 2.2 HUs per acre. Habitat units were associated with the following HEP models: California quail (47.69 HUs), western meadowlark (114.78 HUs), mallard (131.93 HUs), Canada goose (60.34 HUs), and mink (1.38 HUs).

  12. Origin of the Magnus force on a vortex in fermion superfluids and superconductors

    International Nuclear Information System (INIS)

    Simanek, E.

    1995-01-01

    Starting from the time-dependent version of the Feynman-Hellmann theorem, the Magnus force acting on a vortex in fermion superfluid is expressed via the adiabatic curvature over the space of vortex positions. With use of the Bogoliubov--de Gennes approximation, the Magnus force in a homogeneous superfluid at T=0 is shown to originate from virtual transitions between the lowest quasiparticle core bound states. Nonadiabatic corrections to the curvature are obtained to second order in vortex velocity. The adiabatic approximation is shown to break down at a critical velocity equal to the vortex velocity in the first Landau level. The effect of elastic scattering on the Magnus force is discussed in terms of the relaxation-time approximation. It is suggested that this approximation is appropriate only for a large-scale vortex motion. In this case, the effective Magnus force is drastically reduced when the elastic-scattering rate exceeds the core excitation frequency. We conjecture that quantum vortex tunneling is governed by a local Magnus force obtained from the Berry phase approach

  14. Magnus-induced ratchet effects for skyrmions interacting with asymmetric substrates

    Science.gov (United States)

    Reichhardt, C.; Ray, D.; Olson Reichhardt, C. J.

    2015-07-01

    We show using numerical simulations that pronounced ratchet effects can occur for ac driven skyrmions moving over asymmetric quasi-one-dimensional substrates. We find a new type of ratchet effect called a Magnus-induced transverse ratchet that arises when the ac driving force is applied perpendicular rather than parallel to the asymmetry direction of the substrate. This transverse ratchet effect only occurs when the Magnus term is finite, and the threshold ac amplitude needed to induce it decreases as the Magnus term becomes more prominent. Ratcheting skyrmions follow ordered orbits in which the net displacement parallel to the substrate asymmetry direction is quantized. Skyrmion ratchets represent a new ac current-based method for controlling skyrmion positions and motion for spintronic applications.

  15. Magnus force and inertia properties of magnetic vortices in weak ferromagnets

    International Nuclear Information System (INIS)

    2010-01-01

    The question of the Magnus force in weak ferromagnets acting on magnetic vortices (Bloch lines), within domain boundary has been investigated and the general formula of the Magnus force has been derived. It is shown that the Magnus force is non-zero in most types domain boundaries and determined by the average sublattice magnetization, Dzyaloshinskii coupling constants and exchange interaction between the sublattices. Generalized expressions have been obtained for the effective Langrangian and Rayleigh functions in weak ferromagnets allowing for their vortex structure. The mass of a vortex was considered and the value m * ∼ 10 -14 g/cm was obtained for YFeO 3 . The dynamic bending of the domain boundary in the presence of a moving vortex has been analyzed. A formula has been obtained, which describes the dependence of the vortex velocity in a motionless domain boundary upon the magnetic-field.

    1980-01-01

    A recently reported Parabolized Navier-Stokes code has been employed to compute the supersonic flow field about spinning cone, ogive-cylinder, and boattailed bodies of revolution at moderate incidence. The computations were performed for flow conditions where extensive measurements for wall pressure, boundary layer velocity profiles and Magnus force had been obtained. Comparisons between the computational results and experiment indicate excellent agreement for angles of attack up to six degrees. The comparisons for Magnus effects show that the code accurately predicts the effects of body shape and Mach number for the selected models for Mach numbers in the range of 2-4.

    2015-02-01

    The effect of planar defects on the Magnus force in type-II superconductors is studied. It is shown that the deformation of the vortex due to the presence of a planar defect leads to a local decrease in the mean free path of electrons in the vortex. This effect reduces the effective Magnus coefficient in normal direction to the planar defect, leading to an anisotropic regime of the Hall effect. The presented developments here can qualitatively explain experimental observations of the anisotropic Hall effect in high- T c superconductors in the mixed state.

  3. Analgesia induced by morphine microinjected into the nucleus raphe magnus: effects on tonic pain.

    Science.gov (United States)

    Dualé, Christian; Sierralta, Fernando; Dallel, Radhouane

    2007-07-01

    One of the possible sites of action of the analgesic effect of morphine is the Nucleus Raphe Magnus, as morphine injected into this structure induces analgesia in transient pain models. In order to test if morphine in the Nucleus Raphe Magnus is also analgesic in a tonic pain model, 5 microg of morphine or saline (control) were microinjected into the Nucleus Raphe Magnus of the rat. Analgesic effects were assessed following nociceptive stimulation using transient heating of the tail (phasic pain) and subcutaneous orofacial injection of 1.5 % formalin (tonic pain). While morphine was strongly analgesic for the tail-flick response (p <0.0001 compared to control), analgesia on the response to formalin was also observed for both early (p = 0.007) and late responses (p = 0.02). However, the response to formalin was not completely blunted. These results suggest that the Nucleus Raphe Magnus is not the exclusive site of action of morphine-induced analgesia in clinical conditions.

    We here revisit expansion schemes used in nuclear magnetic resonance (NMR) for the calculation of effective Hamiltonians and propagators, namely, Magnus, Floquet, and Fer expansions. While all the expansion schemes are powerful methods there are subtle differences among them. To understand the differences, we performed explicit calculation for heteronuclear dipolar decoupling, cross-polarization, and rotary-resonance experiments in solid-state NMR. As the propagator from the Fer expansion takes the form of a product of sub-propagators, it enables us to appreciate effects of time-evolution under Hamiltonians with different orders separately. While 0th-order average Hamiltonian is the same for the three expansion schemes with the three cases examined, there is a case that the 2nd-order term for the Magnus/Floquet expansion is different from that obtained with the Fer expansion. The difference arises due to the separation of the 0th-order term in the Fer expansion. The separation enables us to appreciate time-evolution under the 0th-order average Hamiltonian, however, for that purpose, we use a so-called left-running Fer expansion. Comparison between the left-running Fer expansion and the Magnus expansion indicates that the sign of the odd orders in Magnus may better be reversed if one would like to consider its effect in order.

    Cadaveric studies indicate that adductor magnus is structurally partitioned into at least two regions. The aim of this study was to investigate the direction-specific actions of proximal and distal portions of adductor magnus, and in doing so determine if these segments have distinct functional roles. Fine-wire EMG electrodes were inserted into two portions of adductor magnus of 12 healthy young adults. Muscle activity was recorded during maximum voluntary isometric contractions (MVICs) across eight tests (hip flexion/extension, internal/external rotation, abduction, and adduction at 0°, 45°, and 90° hip flexion). Median activity within each action (normalized to peak) was compared between segments using repeated measures nonparametric tests (α = 0.05). An effect size (ES = z-score/√sample size) was calculated to determine the magnitude of difference between muscle segments. The relative contribution of each muscle segment differed significantly during internal rotation (P magnus has at least two functionally unique regions. Differences were most evident during rotation. The different direction-specific actions may imply that each segment performs separate roles in hip stability and movement. These findings may have implications on injury prevention and rehabilitation for adductor-related groin injuries, hamstring strain injury, and hip pathology. Clin.

    Negative Magnus lift acting on a sphere rotating about the axis perpendicular to an incoming flow is investigated using large-eddy simulation at three Reynolds numbers of 1.0× 10 4 , 2.0 × 10 5 , and 1.14 × 10 6 . The numerical methods adopted are first validated on a non-rotating sphere and the spatial resolution around the sphere is determined so as to reproduce the laminar separation, reattachment, and turbulent transition of the boundary layer observed at around the critical Reynolds number. In the rotating sphere, positive or negative Magnus effect is observed depending on the Reynolds number and the rotating speed imposed. At the Reynolds number in the subcritical or supercritical region, the direction of the lift force follows the Magnus effect to be independent of the rotational speed tested here. In contrast, negative lift is observed at the Reynolds number at the critical region when particular rotating speeds are imposed. The negative Magnus effect is discussed in the context of the suppression or promotion of boundary layer transition around the separation point.

    Negative Magnus lift acting on a sphere rotating about the axis perpendicular to an incoming flow was investigated using large-eddy simulation at three Reynolds numbers of 1.0 × 104, 2.0 × 105, and 1.14 × 106. The numerical methods used were first validated on a non-rotating sphere, and the spatial resolution around the sphere was determined so as to reproduce the laminar separation, reattachment, and turbulent transition of the boundary layer observed in the vicinity of the critical Reynolds number. The rotating sphere exhibited a positive or negative Magnus effect depending on the Reynolds number and the imposed rotating speed. At Reynolds numbers in the subcritical or supercritical regimes, the direction of the Magnus lift force was independent of the rotational speed. In contrast, the lift force was negative in the critical regime when particular rotating speeds were imposed. This negative Magnus effect was investigated in the context of suppression or promotion of boundary layer transition around the separation point.

    2017-08-01

    The clinical method of motivational interviewing (MI) evolved from the person-centered approach of Carl Rogers, maintaining his pioneering commitment to the scientific study of therapeutic processes and outcomes. The development of MI pertains to all 3 of the 125th anniversary themes explored in this special issue. Applications of MI have spread far beyond clinical psychology into fields including health care, rehabilitation, public health, social work, dentistry, corrections, coaching, and education, directly impacting the lives of many people. The public relevance and impact of clinical psychology are illustrated in the similarity of MI processes and outcomes across such diverse fields and the inseparability of human services from the person who provides them, in that both relational and technical elements of MI predict client outcomes. Within the history of clinical psychology MI is a clear product of clinical science, arising from the seminal work of Carl Rogers whose own research grounded clinical practice in empirical science. As with Rogers' work 70 years ago, MI began as an inductive empirical approach, observing clinical practice to develop and test hypotheses about what actually promotes change. Research on MI bridges the current divide between evidence-based practice and the well-established importance of therapeutic relationship. Research on training and learning of MI further questions the current model of continuing professional education through self-study and workshops as a way of improving practice behavior and client outcomes.

  15. Alexander von Humboldt und Carl Friedrich Gauß als Wegbereiter der neuen Disziplin Erdmagnetismus

    2011-03-01

    Full Text Available AbstractThough Alexander von Humboldt was motivated for the first time to deal with earthmagnetism during his stay in Freiberg, it was in France that he really became a specialist in this respect. During most of his journeys he made earthmagnetic measurements. His collaboration with Arago was of great importance, it was in Paris that the first magnetic observatory was built. Humboldt rendered outstanding services to the investigation of earth magnetism by two major achievements: 1. He emphasized intensity measurements and 2. he put forward the law that the magnetic intensity is increasing from the magnetic equator toward the magnetic poles. At least since 1803 Carl Friedrich Gauss was interested in earthmagnetism and especially in Humboldt’s early published data. That Wilhelm Weber became professor of physics at the University of Göttingen in 1831 was a turning point for Gauss. In 1833 Göttingen was the centre of investigating earthmagnetism, a new era began which lasted only until 1843. Gauss’ main contributions were more or less theoretical, in 1832/3 he transformed Humboldt’s relative intensity measurements into absolute ones which were independent of the instrument’s needle. A new epoch began with Gauss’ publication „Allgemeine Theorie des Erdmagnetismus” (1839. The main point was the newly defined notion of „potential“. Gauss was the first to present the surface of the earth with equipotential lines. ZusammenfassungAlexander von Humboldt hatte sich bereits in Freiberg mit dem Erdmagnetismus beschäftigt; jedoch erst in Frankreich lernte er die entsprechenden Beobachtungsmethoden kennen. Auf allen seinen Reisen machte er erdmagnetische Messungen. Seine Zusammenarbeit mit Arago in Paris war besonders fruchtbar, hier wurde das erste magnetische Observatorium gebaut. Humboldt beschäftigte sich vor allem mit Intensitätsmessungen; sein wichtigster Beitrag war die Feststellung, dass die magnetische Intensität vom

He was 67. Born in Moscow, he entered one of the world's best schools of physics, Moscow Engineering Physics Institute (MEPhI). With this renowned educational and research institution he bonded an alliance for his entire life, starting as an undergraduate student in the Department of Theoretical Physics and later continued as graduate student, assistant professor, associated professor, and full professor in the same department, a rare accomplishment of a person. All those years he retained the love of his life—the love for physics. He worked tirelessly as a teacher and scholar in this captivating field of knowledge. Professor Yevseyev was one of the founders of the international journal of Laser Physics in 1990, the first academic English language journal published in the former USSR. Later, in 2004, the second journal, Laser Physics Letters was brought to the forum of global laser physics community. The idea behind this new title was Professor Yevseyev's initiative to reach the readers and participants with new pioneering and break-through research results more rapidly. His leadership and indefatigable dedication to the quality of published materials made it possible that this journal reached international recognition in a few short years. Still, in order to attract even more attention of potential contributors and readers, Professor Yevseyev originally proposed to conduct the International Laser Physics Workshop (LPHYS) on the annual basis. Since 1992 the Workshop has been conducted every year, each year in a different country. As in all previous years, Professor Yevseyev was the key organizer of this year's workshop in Calgary, Canada.

    2016-08-01

    Granville Stanley Hall (1844-1924) with William James (1842-1910) is the key founder of psychology of religion movement and the first American experimental or genetic psychologist, and Carl Gustav Jung (1875-1961) is the founder of the analytical psychology concerned sympathetically about the religious dimension rooted in the human subject. Their fundamental works are mutually connected. Among other things, both Hall and Jung were deeply interested in how the study of religious experience is indispensable for the depth understanding of human subject. Nevertheless, except for the slight indication, this common interest between them has not yet been examined in academic research paper. So this paper aims to articulate preliminary evidence of affinities focusing on the locus and its function of the inner deep psychic dimension as the religious in the work of Hall and Jung.

    The Carl Zeiss Company of Jena, Germany, introduced the first prototype planetarium in the fall of 1923. By 1933, there were a dozen planetaria in Germany alone, and nearly a dozen more abroad. This talk argues that on one hand, Zeiss saw the planetarium as an opportunity to reintroduce German engineering to a skeptical international market. On the other, Zeiss recognized that a large part of the planetarium’s domestic appeal lay in the romance of its German origins. Through an examination of Zeiss’ corporate correspondence, propaganda, and contemporary international and domestic press, this talk argues that in advertising the planetarium in Germany and abroad, the Zeiss company relied on competing constructions of a post-war German identity rooted in conflicting understandings of space.

    Carl Rogers' classic account (see record 2007-14639-002) of the necessary and sufficient conditions for therapeutic personality change is examined in light of developments in theory and practice since the time he wrote. Rogers' ideas, which diverged from and were very largely a challenge to, the dominant psychoanalytic ideology of the era in which he wrote, are considered in relation to new theoretical developments in what has come to be called relational psychoanalysis. They are also considered in light of the greatly increased influence of and substantial evidence supporting behavioral and cognitive-behavioral approaches. Points of convergence and divergence among these approaches are examined. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

  6. Figuras de la antipolítica en Carl Schmitt

    2008-12-01

    Full Text Available El presente trabajo desarrolla distintas figuras que Carl Schmitt señala como formas de subjetividad antipolítica. Si desde la perspectiva del jurista alemán las operaciones que constituyen un modo de ser político son aquellas que producen o sostienen una forma representativa, lo propio de una subjetividad antipolítica son aquellas operaciones que erosionan o conducen a la destrucción de dicha forma política. El trabajo intenta mostrar que la operación fundamental en este sentido es la dilación, entendida como la postergación indefinida de la decisión. Así, bajo las diversas figuras de la antipolítica que Schmitt aborda, esta operación también adquiere diversas formas de aparición: en el caso de la subjetividad liberal se da bajo la forma de la discusión y el compromiso, en el caso del romántico político bajo la forma de la poetización.This paper develops various figures noted by Carl Schmitt as forms of anti-political subjectivity. Whereas, from the German jurist's perspective, the operations which constitute a political way of being are those which produce and care for a representative form, the specificity of a anti-political subjectivity is shaped by those operations which erode or wear that political form down. The paper aims to show that the main feature of the antipolitical way of being is the delay, meaning the indefinite postponement of the decision as such. Thus, under the various figures of the anti-politics that Schmitt deals with, this operation appears on different manners: the liberal form of postponing is the endless discussion and the compromise; the romatic form is the aesthetization of the world.

    2009-07-01

    In voltage-clamp experimental on slices of the rat brainstem the effects of 5-HT and GABA on serotonergic neurons of nucleus raphe magnus were investigated. Local applications of 5-HT induced an increase in IPCSs frequency and amplitude in 45% of serotonergic cells. The effect suppressed by the blocker of fast sodium channels tetradotoxin. Antagonist of GABA receptor gabazine blocked IPSCs in neurons both sensitive and non-sensitive to 5-HT action. Applications of GABA induced a membrane current (I(GABA)), which was completely blocked by gabazine. The data suggest self-control of the activity of serotonergic neurons in nucleus raphe magnus by negative feedback loop via local GABAergic interneurons.

  11. An existential criterion of normal and abnormal personality in the works of Carl Jung and Carl Rogers

    Directory of Open Access Journals (Sweden)

    Kapustin, Sergey A.

    2016-06-01

    Full Text Available This article is the third in a series of four articles scheduled for publication in this journal. In the first article (Kapustin, 2015a I proposed a description of a new so-called existential criterion of normal and abnormal personality that is implicitly present in the works of Erich Fromm. According to this criterion, normal and abnormal personalities are determined, first, by special features of the content of their position regarding existential dichotomies that are natural to human beings and, second, by particular aspects of the formation of this position. Such dichotomies, entitatively existent in all human life, are inherent, two-alternative contradictions. The position of a normal personality in its content orients a person toward a contradictious predetermination of life in the form of existential dichotomies and necessitates a search for compromise in resolving these dichotomies. This position is created on a rational basis with the person’s active participation. The position of an abnormal personality in its content subjectively denies a contradictious predetermination of life in the form of existential dichotomies and orients a person toward a consistent, noncompetitive, and, as a consequence, onesided way of life that doesn’t include self-determination. This position is imposed by other people on an irrational basis. Abnormality of personality interpreted like that is one of the most important factors influencing the development of various kinds of psychological problems and mental disorders — primarily, neurosis. In the second article (Kapustin, 2015b I showed that this criterion is also implicitly present in the personality theories of Sigmund Freud and Alfred Adler, although in more specific cases. In the current work I prove that this criterion is also present in the personality theories of Carl Jung and Carl Rogers, where it is implicitly stated in a more specific way. In the final article I will show that this criterion

  14. The Magnus-Rademaker Scientific Film Collection: Ethical Issues on Animal Experimentation (1908-1940).

    Koehler, Peter J; Lameris, Bregt

    2016-01-01

    The Magnus-Rademaker scientific film collection (1908-1940) deals with the physiology of body posture by the equilibrium of reflex musculature contractions for which experimental studies were carried out with animals (e.g., labyrinthectomies, cerebellectomies, and brain stem sections) as well as observations done on patients. The films were made for demonstrations at congresses as well as educational objectives and film stills were published in their books. The purpose of the present study is to position these films and their makers within the contemporary discourse on ethical issues and animal rights in the Netherlands and the earlier international debates. Following an introduction on animal rights and antivivisection movements, we describe what Magnus and Rademaker thought about these issues. Their publications did not provide much information in this respect, probably reflecting their adherence to implicit ethical codes that did not need explicit mentioning in publications. Newspaper articles, however, revealed interesting information. Unnecessary suffering of an animal never found mercy in Magnus' opinion. The use of cinematography was expanded to the reduction of animal experimentation in student education, at least in the case of Rademaker, who in the 1930s was involved in a governmental committee for the regulation of vivisection and cooperated with the antivivisection movement. This resulted not only in a propaganda film for the movement but also in films that demonstrate physiological experiments for students with the purpose to avert repetition and to improve the teaching of experiments. We were able to identify the pertinent films in the Magnus-Rademaker film collection. The production of vivisection films with this purpose appears to have been common, as is shown in news messages in European medical journals of the period.

    Theoretical approaches are useful and powerful tools for more accurate and efficient spin dynamics simulation to understand experiments and devising new RF pulse sequence in nuclear magnetic resonance. Solid-state NMR is definitely a timely topic or area of research, and not many papers on the respective theories are available in the literature of nuclear magnetic resonance or physics reports. This report presents the power and the salient features of the promising theoretical approach called Floquet–Magnus expansion that is helpful to describe the time evolution of the spin system at all times in nuclear magnetic resonance. The report presents a broad view of algorithms of spin dynamics, based on promising and useful theory of Floquet–Magnus expansion. This theory provides procedures to control and describe the spin dynamics in solid-state NMR. Major applications of the Floquet–Magnus expansion are illustrated by simple solid-state NMR and physical applications such as in nuclear, atomic, molecular physics, and quantum mechanics, NMR, quantum field theory and high energy physics, electromagnetism, optics, general relativity, search of periodic orbits, and geometric control of mechanical systems. The aim of this report is to bring to the attention of the spin dynamics community, the bridge that exists between solid-state NMR and other related fields of physics and applied mathematics. This review article also discusses future potential theoretical directions in solid-state NMR.

    Thymus magnus, an endemic species, is found in the Republic of Korea. The volatile compounds extracted by SPME from T. magnus were investigated for their chemical composition and electrophysiological response against the Asian tiger mosquito, Aedes albopictus. The volatile compounds of T. magnus as determined by gas chromatography mass spectrometry were gamma-terpinene (33.0%), thymol (29.9%), beta-bisabolene (8.9%), p-cymene (8.3%), alpha-terpinene (5.0%), myrcene (4.7%), beta-caryophyllene (4.0%), alpha-thujene (2.7%), camphene (1.3%), carvacrol (1.2%), and alpha-pinene (1.1%). Among these candidates, thymol exhibited complete (100%) repellent activity against female Ae. albopictus, an effect that was confirmed through evaluating the electrophysiological response on the antenna of Ae. albopictus. The effectiveness of a binary 1:2 mixture of thymol and vanillin (0.05:0.1 microl per cm2) was found to be significantly more effective than thymol alone for a period of 120 min. In addition, thymol, alpha-terpinene, and carvacrol showed high larvicidal activity against on the third-stage larvae with LC50 values of 0.9 microl per 100 ml.

  18. Curveballs in protoplanetary discs - the effect of the Magnus force on planet formation

    Forbes, John C.

    2015-10-01

    Spinning planetesimals in a gaseous protoplanetary disc may experience a hydrodynamical force perpendicular to their relative velocities. We examine the effect this force has on the dynamics of these objects using analytical arguments based on a simple laminar disc model and numerical integrations of the equations of motion for individual grains. We focus in particular on metre-sized boulders traditionally expected to spiral in to the central star in as little as 100 years from 1 au We find that there are plausible scenarios in which this force extends the lifetime of these solids in the disc by a factor of several. More importantly the velocities induced by the Magnus force can prevent the formation of planetesimals via gravitational instability in the inner disc if the size of the dust particles is larger than of the order of 10 cm. We find that the fastest growing linear modes of the streaming instability may still grow despite the diffusive effect of the Magnus force, but it remains to be seen how the Magnus force will alter the non-linear evolution of these instabilities.

    When 1-5C-4 cells were infected with von Magnus virus derived from influenza A/RI/5+ virus by successive undiluted passages in chick embryos, virus-specific proteins were synthesized but production of infectious virus was inhibited. In these cells the synthesis of viral RNA was suppressed and the nucleoprotein (NP) antigen was found predominantly in the nucleus in contrast to standard virus-infected cells in which the antigen was distributed throughout the whole cell. The intracellular location and migration of NP were determined by isotope labeling and sucrose gradient centrifugation of subcellular fractions. In standard virus-infected cell NP polypeptide was present predominantly in the cytoplasm in the form of viral ribonucleoprotein (RNP) and intranuclear RNP was detected in reduced amounts. In contrast, in von Magnus virus-infected cells NP polypeptide was present predominantly in the nucleus in a nonassembled, soluble from and the amount of cytoplasmic RNP was considerably reduced. After short-pulse labeling NP was detected exclusively in the cytoplasm in a soluble form and after a chase a large proportion of such soluble NP was seen in the nucleus. It is suggested that a large proportion of the NP synthesized in von Magnus virus-infected cells in not assembled into cytoplasmic RNP because of the lack of available RNA and the NP migrated into the nucleus and remained there.

    Full Text Available The present article discusses the teaching ethos of professors who are recognized for their good practice as trainers. The aim of our study is to analyze the influences of such professors’ professional constitution, as well as the explicit and/or tacit teaching knowledge they mobilize in their teaching practices. Based on Shulman, Gauthier, Tardif and Polanyi, we conducted interviews with three professors described by their students as reference. They were also observed in their classes, in the context of an undergraduate program in pedagogy at a public university. Data show similarities between the practices of the investigated professors, as well as a consistent description of their didactics, which is marked by intellective, moral, emotional and behavioral features.

  1. [Carl Adolph von Basedow--150th anniversary of his death].

    2004-05-01

    Carl Adolph von Basedow was the son of an aristocratic family and was born 1799 in Dessau. He was the grandson of the famous pedagogue Johann Bernhard Basedow. He studied medicine at the university of Halle and spent two years in the surgical service of Paris hospitals--the Charité and the Hôtel Dieu. In 1822, he settled in Merseburg as a physician. He was soon acclaimed as a genial and skilled helper in all branches of medical practice. He performed his own post-mortem examinations and published findings on a number of different diseases. His famous contribution in the thyroid field appeared in 1840 entitled "Exophthalmos due to hypertrophy of the cellular tissue in the orbit". Exophthalmos, goiter and palpitation of the heart have become known as the Merseburg Triad. In 1848, he published the autopsy findings on a patient who died from "exophthalmic cachexia". In Germany and some other countries, the disease was named as Morbus Basedow since 1858. In 1854 he pricked in his finger in the postmortem room when examining a patient who had died of typhus and he succumbed to septicemia at the early age of fifty-five. The date of his death was April 11, 1854. On April 14, he was laid in the Sixtus Cemetery in Merseburg. Basedow postulated that a wrong mixing of the blood manifested in cell tissue congestion and glandular vegetation cause the manifestations of disease. If we abstract our modern knowledge and accept circulating antibodies and disturbance of the immune balance as a dyscrasia as well as the proliferation of lymphocytic clones and local cellulary infiltration in terms of immune thyroiditis and autoimmune orbitopathy as cell tissue congestion and glandular vegetations, then doubt arise whether we have indeed made much progress in the last 150 years. At least, respect for the genius of the general physician Carl Adolph von Basedow is becoming greater. We may all hope that in the contributions and the discussions, we shall learn where we stand at the end of

Aquí se examina a qué se debe eso. ¿A la contribución del pensamiento de Schmitt para interpretar y aplicar la Ley Fundamental? ¿A las contribuciones de su teoría política? La respuesta a las dos preguntas es negativa. Su fama se debe al lugar que le otorga el mito sobre el positivismo y el decisionismo del derecho en el régimen nazi. Se debe a la dificultad de integrar el pensamiento jurídico del Tercer Reich en la historia de la cultura legal alemana. Un intento de conseguirlo fue recurrir a una equívoca interpretación ad hoc de la persona de Schmitt.

    The current status of Observatory "Carl Sagan" (OCS) of University of Sonora is presented. This project was born in 1996 focused to build a small solar-stellar observatory completely operated by remote control. The observatory will be at "Cerro Azul", a 2480 m peak in one of the best regions in the world for astronomical observation, at the Sonora-Arizona desert. The OCS, with three 16 cm solar telescopes and a 55 cm stellar telescope is one of the cheapest observatories, valuated in US200,000 Added to its scientific goals to study solar coronal holes and Supernovae Type 1A, the OCS has a strong educative and cultural program in Astronomy to all levels. At the end of 2001, we started the Program "Constelacion", to build small planetariums through all the countries with a cost of only US80,000. Also, the webcast system for transmission of the solar observations from the prototype OCS at the campus, was expanded to webcast educational programs in Astronomy since July of this year, including courses and diplomats for Latin American people. All of these advances are exposed here.

    J. S. Shklovsky and Carl Sagan played an outstanding role in modern astronomy. Their names are well known not only to professional astronomers, but also to millions of educated people in many countries, which are interested in modern state of science research. Among these trends of modern science, which are difficult to define, are such problems, as the creation of Solar system, the origin of life on Earth, the evolution of living organisms on Earth from the simplest viruses to Homo Sapiens, the evolution of intelligence and technology. Finally, both outstanding scientists were deeply interested in the problem of SETI (Search Extraterrestrial Intelligence), i.e. search of extraterrestrial civilizations and methods of making contacts with them. And both scientists were high professionals in their fields. Joseph Shklovsky was a theoretical astronomer in all fields of modern astronomy (geophysics and physics of the upper atmosphere of the Earth, Sun and Solar Corona, Interplanetary Medium and Solar Wind, Interstellar Medium, Supernova and their remnants, the Galaxy and galaxies, Quasars and Cosmology). There is hardly a field in modern astrophysics (except perhaps the theory of the interior structure of stars), where Joseph Shklovsky has not l a bright stamp of his talent…

  10. The Carl Sagan solar and stellar observatories as remote observatories

    In this work we summarize recent efforts made by the University of Sonora, with the goal of expanding the capability for remote operation of the Carl Sagan Solar and Stellar Observatories, as well as the first steps that have been taken in order to achieve autonomous robotic operation in the near future. The solar observatory was established in 2007 on the university campus by our late colleague A. Sánchez-Ibarra. It consists of four solar telescopes mounted on a single equatorial mount. On the other hand, the stellar observatory, which saw the first light on 16 February 2010, is located 21 km away from Hermosillo, Sonora at the site of the School of Agriculture of the University of Sonora. Both observatories can now be remotely controlled, and to some extent are able to operate autonomously. In this paper we discuss how this has been accomplished in terms of the use of software as well as the instruments under control. We also briefly discuss the main scientific and educational objectives, the future plans to improve the control software and to construct an autonomous observatory on a mountain site, as well as the opportunities for collaborations.

    2012-02-01

    This study explores broad features of political culture and event of the 1930s and World War 2 years, viewed in relation to the emergence and rapid early growth of the new therapy of Carl Rogers. The paper traces Rogers' early professional life and examines distinctive emphases in sociopolitical thought and development during Franklin D. Roosevelt's leadership as President over the prolonged emergency of the Great Depression and the crisis of the War. The study includes a focus on the President's own outlook and style, pertinent New Deal innovations, and wartime needs. Twelve features of this larger context are discriminated as together having vital importance for the new therapy and its founder. The congruent courses of the macrocontext and of Rogers' innovation are followed to the ending of Roosevelt's life. Direct causation is not attributed, but the evidence adduced newly points to particular contours of a larger environment favorable for the expression of Rogers' values and rare ability. In sum, the author concludes that a synergy of highly conducive historical circumstance and individual exceptionality contributed to the philosophical underpinnings, attitudinal values and early momentum of Rogers' client-centered therapy.

    The beginning of the space age in the late 1950s gave rise to innovative and interdisciplinary research concepts and perspectives, including the concept of "exobiology" as a way to approach the fundamental aspects of biology through a study of life outside of the Earth, if it existed. This concept was embodied by NASA into its formal Exobiology Program and into the philosophy of the program both before and after the Viking missions that were launched to Mars to search for signs of life in 1975. Due to both management flexibility and an acceptance of the interdisciplinary nature of the problem of "life in the universe," NASA program managers, and particularly Richard S Young who ran the Exobiology Program beginning 1967, have made some excellent investments in paradigm altering science of great use both on Earth and on future space missions. The work of Carl Woese is one such example, which has revolutionized our understanding of the microbial world and the relationships of all life on Earth.

  15. Floquet-Magnus expansion for general N-coupled spins systems in magic-angle spinning nuclear magnetic resonance spectra

    Science.gov (United States)

    Mananga, Eugene Stephane; Charpentier, Thibault

    2015-04-01

    In this paper we present a theoretical perturbative approach for describing the NMR spectrum of strongly dipolar-coupled spin systems under fast magic-angle spinning. Our treatment is based on two approaches: the Floquet approach and the Floquet-Magnus expansion. The Floquet approach is well known in the NMR community as a perturbative approach to get analytical approximations. Numerical procedures are based on step-by-step numerical integration of the corresponding differential equations. The Floquet-Magnus expansion is a perturbative approach of the Floquet theory. Furthermore, we address the " γ -encoding" effect using the Floquet-Magnus expansion approach. We show that the average over " γ " angle can be performed for any Hamiltonian with γ symmetry.

    Magnus effect is a phenomenon where pressure difference is created according to Bernoulli's effect due to induced velocity changes caused by a rotating object in a fluid. Using this concept, the idea of delaying boundary layer separation on airfoil by providing moving surface boundary layer control has been developed. In order to analyze the influence of Magnus effect on the aerodynamic performance of an airfoil, there is no alternative of developing an experimental setup. This paper aims to develop such an experimental setup which will be capable of analyzing the influence of Magnus effect on both symmetric and asymmetric airfoils by placing a cylinder at the leading edge. To provide arrangements for a rotating cylinder at the leading edge of airfoil, necessary modifications and additions have been done in the test section of an AF100 subsonic wind tunnel.

    Flow past a rotating cylinder has been investigated using the direct simulation Monte Carlo method. The study focuses on the occurrence of the inverse Magnus effect under subsonic flow conditions. In particular, the variations in the coefficients of lift and drag have been investigated as a function of the Knudsen and Reynolds numbers. Additionally, a temperature sensitivity study has been carried out to assess the influence of the wall temperature on the computed aerodynamic coefficients. It has been found that both the Reynolds number and the cylinder wall temperature significantly affect the drag as well as the onset of lift inversion in the transition flow regime.

    Full Text Available Progress and decline: historical dialect in two texts by Hans Magnus Enzensberger The interpretation of history as a process of dialectical development has been one of the most important ideas of Marxist philosophy. Whereas earlier Marxists optimistically considered this process as steering inevitably towards a sociopolitical utopia, subsequent thinkers in the Marxist tradition, especially those identified as Neo-Marxists (like Theodor Adorno, had a more pessimistic interpretation of dialectics. Influenced especially by Adorno, German poet and social commentator Hans Magnus Enzensberger uses the concept of “historical dialectics” as a seminal theme in two of his literary works: “Mausoleum: siebenunddreißig Balladen aus der Geschichte des Fortschritts” and “Der Untergang der Titanic”. In these two texts the representation of the ambiguity of “Fortschritt” or historical development presupposes a more pessimistic account of the historical process. This ambiguity is present both in a bird’s-eye view of the historical process (“Mausoleum”, and in the focus on one specific historical incident (“Der Untergang der Titanic”. Enzensberger subsequently continues to consider the role of art within this dialectical context. In this article, both Enzensberger’s literary use of the philosophical concept of historical dialectics and its artistic implications (as identified by him are examined.

    The recent but steady trend toward increased magnetic and geometric complexity in the design of wigglers and undulators, of which tapered wigglers, hybrid structures, laced electromagnetic wigglers, magnetic cladding, twisters and magic structures are examples, has caused a need for reliable 3-D computer models and a better understanding of the behavior of magnetic systems in three dimensions. The capabilities of the MAGNUS-3D Group of Programs are ideally suited to solve this class of problems and provide insight into 3-D effects. MAGNUS-3D can solve any problem of Magnetostatics involving permanent magnets, linear or nonlinear ferromagnetic materials and electric conductors of any shape in space. The magnetic properties of permanent magnets are described by the complete nonlinear demagnetization curve as provided by the manufacturer, or, at the user's choice, by a simpler approximation involving the coercive force, the residual induction and the direction of magnetization. The ferromagnetic materials are described by a magnetization table and an accurate interpolation relation. An internal library with properties of common industrial steels is available. The conductors are independent of the mesh and are described in terms of conductor elements from an internal library

    2015-11-01

    The present study investigates the flow over a golf ball and a smooth sphere around the critical Reynolds numbers under both stationary and self-spinning conditions by conducting Large-eddy simulations (LES) based on high resolution unstructured grids. For the stationary cases, the present calculation results validate the promotion of the drag crisis at a relatively lower Reynolds number due to the golf ball dimples. It also shows that the golf ball dimples have a limited effect on the time-dependent lateral force development in the subcritical regime, whereas the dimples are beneficial in suppressing the lateral force oscillations in the supercritical regimes. With spin parameter Γ = 0.1, the drag coefficients for the spinning smooth sphere increase slightly in all Reynolds number regimes when compared to the stationary cases, whereas for the spinning golf ball, the drag force decreases in the critical regime and increases in the supercritical regime. For both spinning models, the inverse Magnus effect was reproduced in the critical regime, whereas in the supercritical regime the ordinary Magnus force was generated. Relatively weaker lift forces were also observed in the cases of the spinning golf balls when compared to the spinning smooth spheres.

    2015-01-01

    Highlights: • Operating cycle of a Magnus effect-based AWE system has been optimized. • The cycle trajectory should be vertical and far from the ground based generator. • Vertical trajectory provides high pulling force that drives the generator. • Large distance from the generator is required for the feasibility of the cycle. - Abstract: The paper presents a control variables optimization study for an airborne wind energy production system. The system comprises an airborne module in the form of a buoyant, rotating cylinder, whose rotation in a wind stream induces the Magnus effect-based aerodynamic lift. Through a tether, the airborne module first drives the generator fixed on the ground, and then the generator becomes a motor that lowers the airborne module. The optimization is aimed at maximizing the average power produced at the generator during a continuously repeatable operating cycle. The control variables are the generator-side rope force and the cylinder rotation speed. The optimization is based on a multi-phase problem formulation, where operation is divided into ascending and descending phases, with free boundary conditions and free cycle duration. The presented simulation results show that significant power increase can be achieved by using the obtained optimal operating cycle instead of the initial, empirically based operation control strategy. A brief analysis is also given to provide a physical interpretation of the optimal cycle results

    Full Text Available The use of several developmental approaches is the researchers’ major preoccupation with the DARRIEUS wind turbine. This paper presents the first approach and results of a wide computational investigation on the aerodynamics of a vertical axis DARRIEUS wind turbine based on the MAGNUS effect. Consequently, wind tunnel tests were carried out to ascertain overall performance of the turbine and two-dimensional unsteady computational fluid dynamics (CFD models were generated to help understand the aerodynamics of this new performance. Accordingly, a moving mesh technique was used where the geometry of the turbine blade was cylinders. The turbine model was created in Gambit modeling software and then read into fluent software for fluid flow analysis. Flow field characteristics are investigated for several values of tip speed ratio (TSR, in this case we generated a new rotational speed ratio between the turbine and cylinder (δ = ωC/ωT. This new concept based on the MAGNUS approach provides the best configuration for better power coefficient values. The positive results of Cp obtained in this study are used to generate energy; on the other hand, the negative values of Cp could be used in order to supply the engines with energy.

  12. Magnus force, Aharonov-Bohm effect, and berry phase in superfluids

    International Nuclear Information System (INIS)

    Sonin, E.

    2001-01-01

    The present paper is an attempt to bring together two points of view in order to find a source of disagreement. I restrict myself with the problem of the Galilean invariant quantum Bose-liquid described by the Gross-Pitaevskii theory. At large scales the theory yields equations of the hydrodynamics of an ideal inviscous liquid. In presence of an ensemble of sound waves (phonons) with the Planck distribution, which is characterized by a locally defined normal velocity, one obtains the two-fluid hydrodynamics. The momentum balance in the area around a moving vortex demonstrates the existence of the Iordanskii force. I also discuss the Berry phase. The Berry phase and the Magnus forces are proportional to the total current circulation at large distances. But the total current circulation contains a normal-fluid contribution, which is proportional to the Iordanski force. Taking this contribution into account, the Berry-phase analysis agrees with the momentum-balance approach. (orig.)

  13. Topological spin transport of photons: the optical Magnus effect and Berry phase

    International Nuclear Information System (INIS)

    Bliokh, K.Yu.; Bliokh, Yu.P.

    2004-01-01

    The Letter develops a modified geometrical optics (GO) of smoothly inhomogeneous isotropic medium, which takes into account two topological phenomena: Berry phase and the optical Magnus effect. Taking into account the correspondence between a quasi-classical motion of a quantum particle with a spin and GO of an electromagnetic wave in smoothly inhomogeneous media, we have introduced the standard gauge potential associated with the degeneracy in the wave momentum space. This potential corresponds to the magnetic-monopole-like field (Berry curvature), which causes the topological spin (polarization) transport of photons. The deviations of waves of right-hand and left-hand polarization occur in the opposite directions and orthogonally to the principal direction of motion. This produces a spin current directed across the principal motion. The situation is similar to the anomalous Hall effect for electrons. In addition, a simple scheme of the experiment allowing one to observe the topological spin splitting of photons has been suggested

  14. Effect of arginine vasopressin in the nucleus raphe magnus on antinociception in the rat.

    Yang, Jun; Chen, Jian-Min; Liu, Wen-Yan; Song, Cao-You; Wang, Cheng-Hai; Lin, Bao-Cheng

    2006-09-01

    Previous work has shown that arginine vasopressin (AVP) regulates antinociception through brain nuclei rather than the spinal cord and peripheral organs. The present study investigated the nociceptive effect of AVP in the nucleus raphe magnus (NRM) of the rat. Microinjection of AVP into the NRM increased pain threshold in a dose-dependent manner, while local administration of AVP-receptor antagonist-d(CH2)5Tyr(Et)DAVP decreased the pain threshold. Pain stimulation elevated AVP concentration in the NRM perfuse liquid. NRM pretreatment with AVP-receptor antagonist completely reversed AVP's effect on pain threshold in the NRM. The data suggest that AVP in the NRM is involved in antinociception.

  15. Temperature effects on drift of suspended single-domain particles induced by the Magnus force

    2018-03-01

    We study the temperature dependence of the drift velocity of single-domain ferromagnetic particles induced by the Magnus force in a dilute suspension. A set of stochastic equations describing the translational and rotational dynamics of particles is derived, and the particle drift velocity that depends on components of the average particle magnetization is introduced. The Fokker-Planck equation for the probability density of magnetization orientations is solved analytically in the limit of strong thermal fluctuations for both the planar rotor and general models. Using these solutions, we calculate the drift velocity and show that the out-of-plane fluctuations of magnetization, which are not accounted for in the planar rotor model, play an important role. In the general case of arbitrary fluctuations, we investigate the temperature dependence of the drift velocity by numerically simulating a set of effective stochastic differential equations for the magnetization dynamics.

  10. Floquet–Magnus theory and generic transient dynamics in periodically driven many-body quantum systems

    International Nuclear Information System (INIS)

    Kuwahara, Tomotaka; Mori, Takashi; Saito, Keiji

    2016-01-01

    This work explores a fundamental dynamical structure for a wide range of many-body quantum systems under periodic driving. Generically, in the thermodynamic limit, such systems are known to heat up to infinite temperature states in the long-time limit irrespective of dynamical details, which kills all the specific properties of the system. In the present study, instead of considering infinitely long-time scale, we aim to provide a general framework to understand the long but finite time behavior, namely the transient dynamics. In our analysis, we focus on the Floquet–Magnus (FM) expansion that gives a formal expression of the effective Hamiltonian on the system. Although in general the full series expansion is not convergent in the thermodynamics limit, we give a clear relationship between the FM expansion and the transient dynamics. More precisely, we rigorously show that a truncated version of the FM expansion accurately describes the exact dynamics for a certain time-scale. Our theory reveals an experimental time-scale for which non-trivial dynamical phenomena can be reliably observed. We discuss several dynamical phenomena, such as the effect of small integrability breaking, efficient numerical simulation of periodically driven systems, dynamical localization and thermalization. Especially on thermalization, we discuss a generic scenario on the prethermalization phenomenon in periodically driven systems. -- Highlights: •A general framework to describe transient dynamics for periodically driven systems. •The theory is applicable to generic quantum many-body systems including long-range interacting systems. •Physical meaning of the truncation of the Floquet–Magnus expansion is rigorously established. •New mechanism of the prethermalization is proposed. •Revealing an experimental time-scale for which non-trivial dynamical phenomena can be reliably observed.

  13. Observations on Professor Hayek's Plan

    Directory of Open Access Journals (Sweden)

    Ludwig von Mises

    2009-01-01

    Full Text Available This memorandum was written at the request of Henry Hazlitt to provide Mises’s comments on and concerns about F.A. Hayek’s initial proposals for what became the Mont Pèlerin Society. Mises stresses that those who favor liberty and freedom and oppose totalitarianism must also oppose interventionism. The memo argues that those who fought and lost against the rising tide of totalitarianism at the turn of the 20th Century lost their battles because they settled for middle-of-the-road policies that conceded considerable ground to the socialists. The weak point in Professor Hayek’s plan is that it relies upon the cooperation of many men who are today’s middle-of-the-roaders. As interventionists, they may not be the hoped-for intellectual pioneers to inspire people to build a freer world.

    Camillo Negro, Professor in Neurology at the University of Torino, was a pioneer of scientific film. From 1906 to 1908, with the help of his assistant Giuseppe Roasenda and in collaboration with Roberto Omegna, one of the most experienced cinematographers in Italy, he filmed some of his patients for scientific and educational purposes. During the war years, he continued his scientific film project at the Military Hospital in Torino, filming shell-shocked soldiers. In autumn 2011, the Museo Nazionale del Cinema, in partnership with the Faculty of Neurosciences of the University of Torino, presented a new critical edition of the neuropathological films directed by Negro. The Museum's collection also includes 16 mm footage probably filmed in 1930 by Doctor Fedele Negro, Camillo's son. One of these films is devoted to celebrating the effects of the so-called "Bulgarian cure" on Parkinson's disease.

  1. Investigation of the effect of finite pulse errors on the BABA pulse sequence using the Floquet-Magnus expansion approach

    Science.gov (United States)

    Mananga, Eugene S.; Reid, Alicia E.

    2013-01-01

    This paper presents a study of finite pulse widths for the BABA pulse sequence using the Floquet-Magnus expansion (FME) approach. In the FME scheme, the first order ? is identical to its counterparts in average Hamiltonian theory (AHT) and Floquet theory (FT). However, the timing part in the FME approach is introduced via the ? function not present in other schemes. This function provides an easy way for evaluating the spin evolution during the time in between' through the Magnus expansion of the operator connected to the timing part of the evolution. The evaluation of ? is particularly useful for the analysis of the non-stroboscopic evolution. Here, the importance of the boundary conditions, which provide a natural choice of ? , is ignored. This work uses the ? function to compare the efficiency of the BABA pulse sequence with ? and the BABA pulse sequence with finite pulses. Calculations of ? and ? are presented.

    Patellar dislocations are associated with injuries to the medial patellofemoral ligament (MPFL). Several techniques for MPFL reconstruction have been recently published with some disadvantages involved, including large skin incisions and donor site morbidity. Arthroscopic stabilizing techniques carry the potential of inadequate restoration of MPFL function. We present a minimally invasive technique for MPFL reconstruction using adductor magnus tendon autograft. This technique is easily performed, safe, and provides a stabilizing effect equal to current MPFL reconstructions. Skin incision of only 3-4 cm is located at the level of the proximal half of the patella. After identifying the distal insertion of the adductor magnus tendon, a tendon harvester is introduced to harvest the medial two-thirds of the tendon, while the distal insertion is left intact. The adductor magnus tendon is cut at 12-14 cm from its distal insertion and transferred into the patellar medial margin. Two suture anchors are inserted through the same incision at the superomedial aspect of the patella in the anatomic MPFL origin. The graft is tightened at 30 degrees knee flexion. Aftercare includes 4 weeks of brace treatment with restricted range of motion.

  6. Sujeito e ordem: romantismo e decisionismo no pensamento de Carl Schmitt

    2002-01-01

    Full Text Available The objective of this article is to discuss the link in the work of Carl Schmitt between the critique of romanticism and the reflection on the themes of sovereignty and decision. Based on an analysis of some key issues in the books Politische Romantik (Political Romanticism, Politische Theologie (Political Theology, and Die Diktatur (The Dictatorship, the article analyzes how, in Carl Schmitt, romanticism and decisionism represent counterpoised conceptual universes, which refer to each other in various aspects. The attempt is thus to highlight both the structurally controversial nature of the German jurist?s ideas and the close ties between his legal/political theory and his critique of the liberal-bourgeois order as a synthesis of modernity.

    The paper deals with Carl Friedrich von Weizsäcker's position within the philosophy of mind. It turns out that Weizsäcker's ontology is based on an unorthodox conception both in the philosophy of physics and in the philosophy of mind. His quantum information theoretic reductionism is based on a subtle combination of atomism and holism, his philosophy of mind connected to this is a neutral monism, which proposes a bold intertwining of mind, matter, and space.

    Throughout their academic careers Carl Rogers and Heinz Kohut developed two contrasting definitions of empathy that influenced the ways in which both men sought to help their clients cope with emotional suffering. These two different understandings of empathy are contrasted to each other and finally compared with the understanding of empathy demonstrated in the teachings and actions of Jesus. It is hoped that through studying these ancient religious narratives we might be able to recover a deeper meaning of empathy.

  18. Mutations in the Plasmodium falciparum Cyclic Amine Resistance Locus (PfCARL Confer Multidrug Resistance

    Directory of Open Access Journals (Sweden)

    Gregory LaMonte

    2016-07-01

    Full Text Available Mutations in the Plasmodium falciparum cyclic amine resistance locus (PfCARL are associated with parasite resistance to the imidazolopiperazines, a potent class of novel antimalarial compounds that display both prophylactic and transmission-blocking activity, in addition to activity against blood-stage parasites. Here, we show that pfcarl encodes a protein, with a predicted molecular weight of 153 kDa, that localizes to the cis-Golgi apparatus of the parasite in both asexual and sexual blood stages. Utilizing clustered regularly interspaced short palindromic repeat (CRISPR-mediated gene introduction of 5 variants (L830V, S1076N/I, V1103L, and I1139K, we demonstrate that mutations in pfcarl are sufficient to generate resistance against the imidazolopiperazines in both asexual and sexual blood-stage parasites. We further determined that the mutant PfCARL protein confers resistance to several structurally unrelated compounds. These data suggest that PfCARL modulates the levels of small-molecule inhibitors that affect Golgi-related processes, such as protein sorting or membrane trafficking, and is therefore an important mechanism of resistance in malaria parasites.

  19. The destruction of the nameless public enemy: an interpretation of the political in Carl Schmitt

    2017-10-01

    Full Text Available This paper proposes a critical analysis of the essential criteria to define the concept of the political as presented by German jurist and philosopher, Carl Schmitt. Based on the essence of the political —i.e. the friend-enemy duality—, the objective is to explore the practical implications resulting from the actual possibilities of confrontation, the key scope being the analysis of a totalitarian potential from a Schmittian´s perspective. In Schmitt´s thought, this distinction is the fundamental reason for the definition of the political. Not every opponent is necessarily the enemy –—the other one, the unknown— and likely to be physically destroyed and exterminated but only a public enemy (hostis. Given its indeterminate nature, the enemy may be prescribed according to the sovereign design or, in the context of Nazi Germany where Carl Schmitt lived, in accordance with the President of the Reich´s designs. A hypothetical-deductive methodology is used in this work based on bibliographical research, in particular regarding Carl Schmitt´s theoretical constructions.

  1. Tolerance to non-opioid analgesics is opioid-sensitive in nucleus raphe magnus

    Merab G Tsagareli

    2011-07-01

    Full Text Available Repeated injection of opioid analgesics can lead to a progressive loss of its effect. This phenomenon is known as tolerance. Several lines of investigations have shown that systemic, intraperitoneal administration or the microinjection of non-opioid analgesics, non-steroidal anti-inflammatory drugs (NSAIDs in the midbrain periaqueductal gray matter induces antinociception with some effects of tolerance. Our recent study has revealed that microinjection of three drugs analgin, ketorolac and xefocam into the central nucleus of amygdala produce tolerance to them and cross-tolerance to morphine. Here we report that repeated administrations of these NSAIDs into the nucleus raphe magnus (NRM in the following four days result in progressively less antinociception, i.e. produce the development of tolerance to these drugs in mail rats. Special control experiments showed that post-treatment with μ-opioid antagonist naloxone in NRM significantly decreased antinociceptive effects of NSAIDs at the first day in behavioral tail flick reflex (TF and hot plate (HP latencies. At the second day, naloxone generally had trend effects in both TF and HP tests impeded the development of tolerance to the antinociceptive effect of non-opioid analgesics. These findings strongly support the suggestion on endogenous opioid involvement in NSAIDs antinociception and tolerance in the descending pain control system. Moreover, repeated injections of NSAIDs progressively lead to tolerance to them, cross-tolerance to morphine and the risk of a withdrawal syndrome. Therefore, these results are important for human medicine too.

  2. The sexologist Albert Moll--between Sigmund Freud and Magnus Hirschfeld.

    2012-04-01

    Albert Moll was one of the most influential sexologists during the first three decades of the twentieth century. In contrast to his rivals Sigmund Freud and Magnus Hirschfeld, his achievements have not yet been recognised adequately. The author gives a comparative account of the work of these three protagonists. This shows that Moll formed some ideas which are regarded as psychoanalytical today before Freud, and that he, in contrast to Hirschfeld, was able to reflect critically on contemporary discourses, such as the debates on racial improvement through eugenics. As scientific theories, Freud's psychoanalysis represented the unconscious, fantasy, experience and latency, while Moll's sexology represented consciousness, ontological reality, behaviour and manifestation. Moll's major disagreement with Hirschfeld's sexology was his advocacy of apolitical and impartial science, whereas Hirschfeld's aim was to achieve sexual reforms politically. Added to these differences were strong personal animosities. Freud called Moll a 'beast' and 'pettifogger'; and Moll complained about Hirschfeld's 'problematic' character. When Hirschfeld escaped the Nazi terror and went to Paris, Moll denounced him in order to prevent him rebuilding a new existence in exile.

  3. Between Ideologies and a Hard Place: Hans Magnus Enzensberger's Utopian Pragmatist Poetics

    Directory of Open Access Journals (Sweden)

    1997-01-01

    Full Text Available The marginalization of poetry in North American culture makes it difficult to appreciate fully on this side of the Atlantic the importance of Hans Magnus Enzensberger's literary and cultural contributions over the past four decades. Working against familiar cultural encodings that would align poetry uncritically with the "personal" and prose with the "political," his oeuvre makes a strong case for poetry and critical prose as vitally complementary activities. In his 1991 collection of poems, Zukunftsmusik (Future Music and his 1993 prose collection, Civil Wars: From L.A. to Bosnia , Enzensberger renews his longstanding commitment to "the process / of becoming human." Taken together, the two collections suggest the importance of maintaining connections across genres and their constituencies. In the context of the chaotic civil wars and "great migrations" that have shaped global culture since 1989, Enzensberger's thoroughgoing attention to internal differences within language and culture offers a model of hopeful resistance to an increasingly unreflective culture. His recent writing calls us to look carefully into what poetry will become, and for whom, in the wake of 1989.

  4. Black holes and fundamental fields: Hair, kicks, and a gravitational Magnus effect

    Scalar fields pervade theoretical physics and are a fundamental ingredient to solve the dark matter problem, to realize the Peccei-Quinn mechanism in QCD or the string-axiverse scenario. They are also a useful proxy for more complex matter interactions, such as accretion disks or matter in extreme conditions. Here, we study the collision between scalar "clouds" and rotating black holes. For the first time we are able to compare analytic estimates and strong field, nonlinear numerical calculations for this problem. As the black hole pierces through the cloud it accretes according to the Bondi-Hoyle prediction, but is deflected through a purely kinematic gravitational "anti-Magnus" effect, which we predict to be present also during the interaction of black holes with accretion disks. After the interaction is over, we find large recoil velocities in the transverse direction. The end-state of the process belongs to the vacuum Kerr family if the scalar is massless, but can be a hairy black hole when the scalar is massive.

  5. Opioid microinjection into raphe magnus modulates cardiorespiratory function in mice and rats.

    The raphe magnus (RM) participates in opioid analgesia and contains pain-modulatory neurons with respiration-related discharge. Here, we asked whether RM contributes to respiratory depression, the most prevalent lethal effect of opioids. To investigate whether opioidergic transmission in RM produces respiratory depression, we microinjected a mu-opioid receptor agonist, DAMGO, or morphine into the RM of awake rodents. In mice, opioid microinjection produced sustained decreases in respiratory rate (170 to 120 breaths/min), as well as heart rate (520 to 400 beats/min). Respiratory sinus arrhythmia, indicative of enhanced parasympathetic activity, was prevalent in mice receiving DAMGO microinjection. We performed similar experiments in rats but observed no changes in breathing rate or heart rate. Both rats and mice experienced significantly more episodes of bradypnea, indicative of impaired respiratory drive, after opioid microinjection. During spontaneous arousals, rats showed less tachycardia after opioid microinjection than before microinjection, suggestive of an attenuated sympathetic tone. Thus, activation of opioidergic signaling within RM produces effects beyond analgesia, including the unwanted destabilization of cardiorespiratory function. These adverse effects on homeostasis consequent to opioid microinjection imply a role for RM in regulating the balance of sympathetic and parasympathetic tone.

  6. Floquet-Magnus theory and generic transient dynamics in periodically driven many-body quantum systems

    Kuwahara, Tomotaka; Mori, Takashi; Saito, Keiji

    2016-04-01

    This work explores a fundamental dynamical structure for a wide range of many-body quantum systems under periodic driving. Generically, in the thermodynamic limit, such systems are known to heat up to infinite temperature states in the long-time limit irrespective of dynamical details, which kills all the specific properties of the system. In the present study, instead of considering infinitely long-time scale, we aim to provide a general framework to understand the long but finite time behavior, namely the transient dynamics. In our analysis, we focus on the Floquet-Magnus (FM) expansion that gives a formal expression of the effective Hamiltonian on the system. Although in general the full series expansion is not convergent in the thermodynamics limit, we give a clear relationship between the FM expansion and the transient dynamics. More precisely, we rigorously show that a truncated version of the FM expansion accurately describes the exact dynamics for a certain time-scale. Our theory reveals an experimental time-scale for which non-trivial dynamical phenomena can be reliably observed. We discuss several dynamical phenomena, such as the effect of small integrability breaking, efficient numerical simulation of periodically driven systems, dynamical localization and thermalization. Especially on thermalization, we discuss a generic scenario on the prethermalization phenomenon in periodically driven systems.

    2006-12-01

    The biography of the former member of the Saxonian Academy of Sciences, Carl Christian Bruhns, and appropiately published in their Transactions, originated from a series of lectures given some years ago. Gisela Munzel and Hans-Joachim Ilgauds, who have already written an authoritative history of Leipzig observatories, joined geophysicist Michael Borngen to describe various aspects of Bruhns' life and activities in different scientific fields. For the astronomical reader, Gisela Munzel's contribution is certainly the most rewarding one, and it covers almost the complete first half of the book. She not only describes Bruhns' astronomical career, but also supplies many details of his life. Having passed something equivalent to a junior high school, his father urged him to become apprentice in his own field, that of a locksmith. C.C. Bruhns became a mechanic in several companies in Berlin, and started also part-time work as a computer at Berlin Observatory in 1851. He soon was "discovered" by its director Johann Franz Encke, and became second assistant in mid-1852, first assistant in 1854 and observer in 1855. In mid-1856 he received his PhD on the topic of minor planets. A prize assignment on astronomical refraction developed into his habilitation thesis of 1859. When in 1857 the observer Heinrich d'Arrest left Leipzig Observatory, there were plans to replace him by an astronomer who would later also take over the post of the aging August Ferdinand Mobius. There were already plans to move the old Observatory on the tower of Pleissenburg castle to another location, when Bruhns was appointed observer and professor in April 1860. In Summer, construction of the new Observatory at Johannistal started, and it was inaugurated in late 1861. Munzel faithfully traces his work, his assistants and colleagues - Engelmann, Weinek, Zollner, and many more - , his activities in the founding of the Astronomische Gesellschaft, his work as a commissar of the ``Mitteleuropaische

    Full Text Available ABSTRACT The aim of this study was to identify the prevalence of satisfaction among accounting professors in Brazil throughout their careers. The research is classified as descriptive and used a quantitative approach to data analysis. 641 valid responses were obtained from professors from all regions of Brazil. The results show that a feeling of satisfaction prevails among accounting course professors, as most of them “like the profession” and, in general, "are satisfied with it”. It was found that levels of satisfaction are higher among individuals with more experience, in that in their first years in the job (one to three years, professors have lower satisfaction rates; the highest levels of satisfaction are found in the final stage (over 35 years. The main factor that influences satisfaction is personal fulfillment (teaching work and relationship with students. It was also possible to identify that positive feelings about teaching predominate (67.3% compared to negative ones (32.7%. These results show the need for greater attention to be paid in the early years of the career in order to avoid a "reality clash". They also show the need for other studies to investigate how the phases in the life cycle of accounting professors are characterized.

    As the title of my paper indicates, Dr. Rudolph Binion was my professor, mentor, and a leading psychohistorian. My paper in memoriam to Rudolph Binion is intended as both a retrospective and an introspective account of my relationship with him, as he had a pivotal influence on me when he was my professor at Columbia University. His help and influence continued after I left graduate school. In my paper I also deal with the enormous stresses of navigating through graduate school, for those students whose goal was to earn the Ph.D. degree. Some examinations were dreaded, For Example The "Examination in Subjects," popularly called the "Oral Exam." The "incubation" period was long indeed, frequently averaging nearly ten years, and it was an ordeal, as the rate of attrition was very high. There is then also the question of "ego strength" and that of "transference" toward the professor. Graduate school is indeed a long and strenuous challenge. I took a seminar in modern French history, a requirement for the Master's degree with Professor Binion, which was consequential for me, as he taught me to be objective in writing history. Professor Binion was a demanding and outstanding teacher.

And every morning, as the Professor and the Housekeeper are introduced to each other anew, a strange and beautiful relationship blossoms between them. Though he cannot hold memories for long (his brain is like a tape that begins to erase itself every eighty minutes), the Professor's mind is still alive with elegant equations from the past. And the numbers, in all of their articulate order, reveal a sheltering and poetic world to both the Housekeeper and her young son.

    To examine the anatomic MRI characteristics of the adductor magnus mini hamstring (AMMH) and explore its involvement in cases of hamstring avulsion. An IRB-approved retrospective review of patients undergoing ''hamstring protocol'' MRI between March 2009 and June 2014 was performed. Two musculoskeletal radiologists recorded multiple AMMH anatomic characteristics and involvement in cases of hamstring avulsion. Seventy-six AMMHs were analyzed in 66 patients [35 females and 31 males, mean age 49.3 ± 15.2 years (range 17-81)]. Eleven percent of AMMHs were poorly visualized, 51 % visualized, and 37 % well visualized. Seven percent demonstrated round, 73 % ovoid, and 21 % flat/lenticular tendon morphologies. Most (88 %) demonstrated typical origins. Average cross-sectional area (CSA) was 22.4 ± 10.6 mm 2 (range 6-56), diameter was 7.2 ± 2.5 mm (range 2.9-15), medial distance from the semimembranosus tendon was 7.5 ± 2.5 mm (range 3-14), and tendon length was 6.8 ± 3.3 cm (range 1.2-14.1). There was no gender difference in AMMH anatomic measurements or correlation between age and CSA or diameter. Of 17 complete hamstring avulsion cases, the AMMH was intact in 13, partially torn in 3, and completely torn in 1. The AMMH is a constant finding with variable anatomic characteristics. It is visualized or well visualized by MRI in 88 % of cases and is a sizable tendon located in close proximity to the semimembranosus tendon. Because it is uncommonly completely torn (6 %) in cases of complete hamstring avulsion, radiologists should be aware of its presence and appearance to avoid diagnostic confusion. (orig.)

Because it is uncommonly completely torn (6 %) in cases of complete hamstring avulsion, radiologists should be aware of its presence and appearance to avoid diagnostic confusion. (orig.)

    Repeated injection of opioid analgesics can lead to a progressive loss of effect. This phenomenon is known as tolerance. Several lines of investigations have shown that systemic, intraperitoneal administration or the microinjection of non-opioid analgesics, non-steroidal anti-inflammatory drugs (NSAIDs) into the midbrain periaqueductal gray matter induces antinociception with some effects of tolerance. Our recent study has revealed that microinjection of three drugs analgin, ketorolac, and xefocam into the central nucleus of amygdala produce tolerance to them and cross-tolerance to morphine. Here we report that repeated administrations of these NSAIDs into the nucleus raphe magnus (NRM) in the following 4 days result in progressively less antinociception compare to the saline control, i.e., tolerance develops to these drugs in male rats. Special control experiments showed that post-treatment with the μ-opioid antagonist naloxone into the NRM significantly decreased antinociceptive effects of NSAIDs on the first day of testing in the tail-flick (TF) reflex and hot plate (HP) latency tests. On the second day, naloxone generally had trend effects in both TF and HP tests and impeded the development of tolerance to the antinociceptive effect of non-opioid analgesics. These findings strongly support the suggestion of endogenous opioid involvement in NSAIDs antinociception and tolerance in the descending pain-control system. Moreover, repeated injections of NSAIDs progressively lead to tolerance to them, cross-tolerance to morphine, and the risk of a withdrawal syndrome. Therefore, these results are important for human medicine too.

    In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

  17. Nonlinear Magnus-induced dynamics and Shapiro spikes for ac and dc driven skyrmions on periodic quasi-one-dimensional substrates

    Science.gov (United States)

    Reichhardt, Charles; Reichhardt, Cynthia J. Olson

    We numerically examine skyrmions interacting with a periodic quasi-one-dimensional substrate. When we drive the skyrmions perpendicular to the substrate periodicity direction, a rich variety of nonlinear Magnus-induced effects arise, in contrast to an overdamped system that shows only a linear velocity-force curve for this geometry. The skyrmion velocity-force curve is strongly nonlinear and we observe a Magnus-induced speed-up effect when the pinning causes the Magnus velocity response to align with the dissipative response. At higher applied drives these components decouple, resulting in strong negative differential conductivity. For skyrmions under combined ac and dc driving, we find a new class of phase locking phenomena in which the velocity-force curves contain a series of what we call Shapiro spikes, distinct from the Shapiro steps observed in overdamped systems. There are also regimes in which the skyrmion moves in the direction opposite to the applied dc drive to give negative mobility.

  18. Vortex currents in turbulent superfluid and classical fluid channel flow, the magnus effect, and Goldstone boson fields

    Expressing hydrodynamics in terms of the flow of vorticity, using the vortex current tensor, helps unify the picture of turbulent channel flow for viscous fluids and for superfluids. In both, eddy viscosity plays a major role in energy dissipation, and in both there is a similar cross stream flow of vorticity, which in the case of superfluids leads to the Josephson frequency. The vortex current tensor, which was introduced in an earlier paper to derive an exact three dimensional Magnus effect formula, turns out to be the classical hydrodynamic limit of the vortex current that is the source for a classical Goldstone-boson field

    This paper provides a precise and efficacious methodology for manifesting forced vibration response with respect to the time-variant linear rotational structure subjected to unbalanced excitation. A modified algorithm based on time step precise integration method and Magnus expansion is developed for instantaneous dynamic problems. The iterative solution is achieved by the ideology of transition and dimensional increment matrix. Numerical examples on a typical accelerating rotation system considering gyroscopic moment and mass unbalance force comparatively demonstrate the validity, effectiveness and accuracy with Newmark-β method. It is shown that the proposed algorithm has high accuracy without loss efficiency.

    The parameters are established which are important to the stability of a boundary layer flow over a yawed spinning cylinder in a uniform stream. It is shown that transition occurs asymmetrically in general and this asymmetry can be important for the prediction of aerodynamic forces and moments (e.g., the Magnus effect). Instability of the steady-state boundary layer flow is determined using small disturbance theory. Although the approach is strictly valid only for the calculation of the conditions for stability in the small, experimental data indicate that in many problems, it provides a good estimate for the transition to turbulence.

    This Alternative Gallery feature introduces the photographic artist Professor Richard Sawdon Smith. Professor Sawdon Smith's work stems around a fascination with representations of anatomy that have been fuelled by his experience as a hospital patient. The work has allowed him to explore ideas through the use of medical illustrations which include early anatomical drawings, personal medical photography and facial modelling. The work highlights how such imagery can be used in the context of a patient seeking understanding and acceptance of ill health and disease using the body as a canvas on which to translate the experience.

    2004-01-01

    Carl Cohen's arguments against animal rights are shown to be unsound. His strategy entails that animals have rights, that humans do not, the negations of those conclusions, and other false and inconsistent implications. His main premise seems to imply that one can fail all tests and assignments in a class and yet easily pass if one's peers are passing and that one can become a convicted criminal merely by setting foot in a prison. However, since his moral principles imply that nearly all exploitive uses of animals are wrong anyway, foes of animal rights are advised to seek philosophical consolations elsewhere. I note that some other philosophers' arguments are subject to similar objections.

    2016-01-01

    The thesis that the theory of charismatic-plebiscitary democracy developed by Max Weber in the wake of the Weimar Republic was developed to its ultimate consequences by Carl Schmitt in the final crisis of Weimar has been hotly debated since it was first advanced in the 1950s. This paper proposes a fresh look at the controversy. By comparing both authors' concepts of politics in their relation to the problem of modernity, it argues that the Weber-Schmitt affair is neither a baseless legend nor a case of natural continuity. Instead, it should rather be understood in terms of a contingent affinity.

The initial hypothesis is that the presence of a population marked by representative differences promotes the collision between freedoms as seen during the “collective rape" in Cologne - Germany. The theme is justified because it affects millions of people worldwide. The method used is the deductive and the work is divided into three parts dealing with the figure of the "other”, representativeness and Criminology of Anomie, presenting a research in development with partial results.

    2011-01-01

    I conducted a 3-year study at Lake Carl Blackwell, Oklahoma to estimate effects of various fishing gears on the flathead catfish Pylodictis olivaris population. Managers were particularly interested in the effect of handfishing or noodling on this population. I used a phone survey to assess angler effort and electrofishing and gill nets to calculate standard population metrics to assess composition of the current population. Survey data indicated that fishing effort and harvest were highest for trotlines and juglines and lowest for noodling. Size distribution of fish harvested by noodlers was not different from sizes that were available in the fishery and was similar to those fish harvested with other gears. Flathead catfish Sampled in Lake Carl Blackwell ranged in size from 38 to 1,220 mm total length, and 77% of the population was less than 508 mm (minimum legal size). Estimated total annual mortality was about 11%. Proportional size distribution (PSD) of flathead catfish for Lake Carl Blackwell indicates that about 70% of legal-sized flathead catfish were over the preferred size of 710 mm. Overall, the Lake Carl Blackwell flathead catfish population appeared healthy. There were a wide range of sizes and ages in the population, and PSD indicated a well-balanced population with many preferred and memorable-sized fish. Due to its rarity, noodling is probably not adversely influencing the population. Additionally, noodling at Lake Carl Blackwell does not appear to be as size-selective as previously thought.

  2. [Carl Ludwig and his place in the history of kidney physiology].

    Science.gov (United States)

    From, Jesper

    2015-01-01

    Only very little was known about the physiology of the kidneys until the middle of the 19th century. The turning point came in 1842 when the famous German physiologist and physician Carl Ludwig (1816-1895) presented a theory about a two-step process (filtration and reabsorption) leading to the excretion of urine. This paper turns the highlights on Ludwig and the period in which he lived. It also tells the story about the anatomical studies in the 17th century and the chemical approaches to urine and kidney physiology in the 18th century preceding the research of Carl Ludwig. The theory of filtration and reabsorption was opposed by another theory (the secretion theory) regarding the kidney as a gland, like for instance the salivary glands. The origin of this theory can be dated back to Marcello Malpighi (1628-1694) in the Renaissance, but it was carried further on by William Bowman (1816-1892) and especially Rudolph Heidenhain (1834-1897) in the 19th century. The research in the 1920's and 1930's marked the end of the fight between the two theories. It proofed that Ludwig was right and it gave him posthumously the recognition that he all the time had deserved.

    Full Text Available Margaret Fuller, the 19th-century feminist and Transcendentalist, has been compared with Louisa May Alcott, Ralph Waldo Emerson, Nathaniel Hawthorne, and Henry David Thoreau. The life and theories of Carl Jung, the 20th-century psychiatrist, have been compared with the works of Sigmund Freud, Alfred Adler, Jean Piaget, and Sabina Spielrein among others. However, no comparisons have been published concerning the beliefs and works of Fuller and Jung. The purpose of this research was to compare and contrast the beliefs and written works of Margaret Fuller and Carl Jung. Similarities and differences were reported among their ideologies. Similarities in their childhood and adult dreams, literary references, spiritual beliefs, and explorations of gender were described. Differences were reported, which included the focus of their writings and their ideas about who is to blame when things go wrong, and how to deal with the individual daemon in each person was also explored. Special consideration was given to how closely their writings intersect. Specifically, the authors questioned whether Jung was inspired by the ideas and writings of Fuller. To answer this question, five possibilities were identified.

  4. Adaptive camouflage: what can be learned from the wetting behaviour of the tropical flat bugs Dysodius lunatus and Dysodius magnus

    Directory of Open Access Journals (Sweden)

    Florian Hischen

    2017-08-01

    Full Text Available The neotropical flat bug species Dysodius lunatus and Dysodius magnus show a fascinating camouflage principle, as their appearance renders the animal hardly visible on the bark of trees. However, when getting wet due to rain, bark changes its colour and gets darker. In order to keep the camouflage effect, it seems that some Dysodius species benefit from their ability to hold a water film on their cuticle and therefore change their optical properties when also wetted by water. This camouflage behaviour requires the insect to have a hydrophilic surface and passive surface structures which facilitate the liquid spreading. Here we show morphological and chemical characterisations of the surface, especially the cuticular waxes of D. magnus. Scanning electron microscopy revealed that the animal is covered with pillar-like microstructures which, in combination with a surprising chemical hydrophilicity of the cuticle waxes, render the bug almost superhydrophilic: water spreads immediately across the surface. We could theoretically model this behaviour assuming the effect of hemi-wicking (a state in which a droplet sits on a rough surface, partwise imbibing the structure around.  Additionally the principle was abstracted and a laser-patterned polymer surface, mimicking the structure and contact angle of Dysodius wax, shows exactly the behaviour of the natural role model – immediate spreading of water and the formation of a thin continuous water film changing optical properties of the surface.

  5. Investigation of the Effect of Finite Pulse Errors on BABA Pulse Sequence Using Floquet-Magnus Expansion Approach.

    Science.gov (United States)

    Mananga, Eugene S; Reid, Alicia E

    This paper presents the study of finite pulse widths for the BABA pulse sequence using the Floquet-Magnus expansion (FME) approach. In the FME scheme, the first order F 1 is identical to its counterparts in average Hamiltonian theory (AHT) and Floquet theory (FT). However, the timing part in the FME approach is introduced via the Λ 1 ( t ) function not present in other schemes. This function provides an easy way for evaluating the spin evolution during "the time in between" through the Magnus expansion of the operator connected to the timing part of the evolution. The evaluation of Λ 1 ( t ) is useful especially for the analysis of the non-stroboscopic evolution. Here, the importance of the boundary conditions, which provides a natural choice of Λ 1 (0) is ignored. This work uses the Λ 1 ( t ) function to compare the efficiency of the BABA pulse sequence with δ - pulses and the BABA pulse sequence with finite pulses. Calculations of Λ 1 ( t ) and F 1 are presented.

    2004-01-01

    We present a modification of the geometrical optics method, which allows one to properly separate the complex amplitude and the phase of the wave solution. Applying this modification to a smoothly inhomogeneous isotropic medium, we show that in the first geometrical optics approximation the medium is weakly anisotropic. The refractive index, being dependent on the direction of the wave vector, contains the correction, which is proportional to the Berry geometric phase. Two independent eigenmodes of right-hand and left-hand circular polarizations exist in the medium. Their group velocities and phase velocities differ. The difference in the group velocities results in the shift of the rays of different polarizations (the optical Magnus effect). The difference in the phase velocities causes an increase of the Berry phase along with the interference of two modes leading to the familiar Rytov law about the rotation of the polarization plane of a wave. The theory developed suggests that both the optical Magnus effect and the Berry phase are accompanying nonlocal topological effects. In this paper the Hamilton ray equations giving a unified description for both of these phenomena have been derived and also a novel splitting effect for a ray of noncircular polarization has been predicted. Specific examples are also discussed

    Professor WU Zhongchao has unique application of penetration needling in clinical treatment. Professor WU applies penetration needling along meridians, and the methods of penetration needling include self-meridian penetration, exterior-interior meridian penetration, identical-name meridian penetration, different meridian penetration. The meridian differentiation is performed according to different TCM syndromes, locations and natures of diseases and acupoint nature, so as to make a comprehensive assessment. The qi movement during acupuncture is focused. In addition, attention is paid on anatomy and long-needle penetration; the sequence and direction of acupuncture is essential, and the reinforcing and reducing methods have great originality, presented with holding, waiting, pressing and vibrating. Based on classical acupoint, the acupoint of penetration needling is flexible, forming unique combination of acupoints.

    2017-01-01

    ABSTRACT Objective: to analyze the work process of nursing professors. Method: descriptive, exploratory and qualitative study, developed with a focus on critical epidemiology, carried out at a School of Nursing in Chile. The research subjects consist of 17 nursing professors, with whom individual semi-structured interviews were carried out and nine participated in a focus group. The Ethics Committee approved this study. Results: 88.2% were female, mean age of 42 years, 47% were married, 94% were Chilean, average length of service in the institution of 2.8 years, and 23.5% had a master’s degree. Regarding the work process, the students were the work object, the tools used were the knowledge and the experience as a nurse, and the work environment was considered good. Regarding the form of work organization, 76% have a 44-hour workweek, the wage was considered inadequate and the workload was higher than foreseen in the contract. The dialectic of the nursing work process is evidenced, demonstrating the contradiction between the low wages and labor overload and the narratives reporting a good work environment, personal fulfillment and transcendence that goes far beyond work. Conclusions: the work process allows describing the work components of the nursing professors, which are consistent with the results of the literature and show the dialectic of the nursing work process.

    2016-06-01

    This paper presents a complete overview of the scientific, professional and social activity of a great Polish pathologist, Witold Nowicki (1878-1941), from mainly Polish-written, original sources with a major impact on mostly his own publications. The biographical commemoration of this eminent professor is not only due to the fact that he provided a profound microscopic characterization of pneumatosis cystoides in 1909 and 1924. Nowicki greatly influenced the development of anatomical pathology in Poland, having authored over 82 publications, with special reference to tuberculosis, lung cancer, sarcomatous carcinomas, scleroma and others. However, the first of all his merits for the readership of Polish pathologists was his textbook titled Anatomical Pathology, which was a basic pathology manual in pre-war Poland. Witold Nowicki - as the head of the academic pathological anatomy department and former dean of the medical faculty - was shot with other professors by Nazi Germans in the Wuleckie hills in Lvov during World War Two. Professor Nowicki was described as being "small in size but great in spirit" by one of his associates, and remains an outstanding example of a meticulous pathologist, a patient tutor and a great social activist to follow.

    1998-04-01

    This paper describes CARL (Computer Assisted Relaxation Learning), a computerized, exposure-based therapy program for the treatment of dental injection fear. The CARL program operates primarily in two different modes; in vitro, which presents a video-taped exposure hierarchy, and in vivo, which presents scripts for a dentist or hygienist to use while working with a subject. Two additional modes are used to train subjects to use the program and to administer behavioral assessment tests. The program contains five different modules, which function to register a subject, train subjects to use physical and cognitive relaxation techniques, deliver an exposure hierarchy, question subjects about the helpfulness of each of the therapy components, and test for memory effects of anxiolytic medication. Nine subjects have completed the CARL therapy program and 1-yr follow-up as participants in a placebo-controlled clinical trial examining the effects of alprazolam on exposure therapy for dental injection phobia. All nine subjects were able to receive two dental injections, and all reduced their general fear of dental injections. Initial results therefore indicate that the CARL program successfully reduces dental injection fear.

  8. Similarities between Prescott Lecky's theory of self-consistency and Carl Rogers' self-theory.

    Merenda, Peter F

    2010-10-01

    The teachings of Prescott Lecky on the self-concept at Columbia University in the 1920s and 1930s and the posthumous publications of his book on self-consistency beginning in 1945 are compared with the many publications of Carl Rogers on the self-concept beginning in the early 1940s. Given that Rogers was a graduate student at Columbia in the 1920s and 1930s, the striking similarities between these two theorists, as well as claims attributed to Rogers by Rogers' biographers and writers who have quoted Rogers on his works relating to self-theory, strongly suggest that Rogers borrowed from Lecky without giving him the proper credit. Much of Rogers' writings on the self-concept included not only terms and concepts which were original with Lecky, but at times these were actually identical.

Scanning electron microscopy was used to analyze the effect of the yeast on inoculations done after harvest. Results showed that C. magnus is able to colonize wound surfaces much faster than the pathogen, outcompeting the later for space and probably for nutrients. In addition, C. magnus produces a flocculent matrix, which affects hyphae integrity. The competition for space and the production of substances that affect hyphae integrity are among the most important modes of action of this yeast.O objetivo deste trabalho foi investigar prováveis modos de ação da levedura Cryptococcus magnus, que resultam no controle da antracnose (Colletotrichum gloeosporioides em frutos de mamoeiro na póscolheita.

    2008-01-01

    Magnus Schmid seems to have been an "ordinary historian of medicine" from 1950 to 1977 in Munich and Erlangen. Following his death he became forgotten by his colleagues. But despite the fact, that he did not publish great books, he modernized the subject and was open to new interpretations of history of medicine and to intercultural views on history. For more than 20 years he seemed to be a quite liberal researcher, but following the changes in society after the 1968/69 revolt, he became a fighter for a new conservatism. Schmid was unwilling to accept that people decided freely about their body and health, without consulting doctors like him while he believed in an unchangeable foundation of ethics in medicine (e. g. abortion). So Schmid, in the last years of his life to the fact, made his valuable scientific works disappear behind his dubious campaigning against the modernized western German society.

    2001-06-22

    The aim of the present study is to investigate the effects of orphanin FQ (OFQ) microinjected into the nucleus raphe magnus (NRM) and the nucleus reticularis gigantocellularis (NGC) on pain modulation. The tail-flick latency (TFL) was used as a behavioral index of nociceptive responsiveness. The result showed microinjection of OFQ into the NRM significantly increased the TFL, whereas microinjection of OFQ into the NGC decreased the TFL, suggesting the analgesic effect of OFQ in the NRM and the hyperalgesic effect of OFQ in the NGC. As there are three classes of putative pain modulating neurons in the rostral ventromedial medulla (RVM), the hyperalgesic or analgesic effect of OFQ in the RVM might depend upon the different class of the neurons being acted.

    A computational method, designated 'SPB', is proposed for the automatic determination of the stream function Phi on an arbitrarily profiled body without recourse to empirical factors. The method is applied to the case of a rotating, circular cross-section cylinder in a uniform shear flow, and the results obtained are compared with those of both the method in which the value of Phi is fixed on a body and the conventional empirical method; it is in view of this established that the SPB method is very efficient and applicable to both steady and unsteady flows. The SPB method, in addition to yielding the aerodynamic forces acting on a cylinder, shows that the Magnus effect lift force decreases as the velocity gradient of the shear flow increases while the cylinder's rotational speed is kept constant.

    Science.gov (United States)

    Meng, W

    1999-04-01

    Carl Adolph von Basedow was the son of an aristocratic family and was born 1799 in Dessau. He was the grandson of the famous pedagogue Johann Bernhard Basedow. He studied medicine at the university of Halle and spent two years in the surgical service of Paris hospitals--the Charité and the Hôtel Dieu. In 1822, he settled in Merseburg as a physician. He was soon acclaimed as a genial and skilled helper in all branches of medical practice. He performed his own post-mortem examinations and published findings on a number of different diseases. His famous contribution in the thyroid field appeared in 1840 entitled "Exophthalmos due to hypertrophy of the cellular tissue in the orbit". Exophthalmos, goiter and palpitation of the heart have become known as the Merseburg Triad. In 1848, he published the autopsy findings on a patient who died from "exophthalmic cachexia". In Germany and some other countries, the disease was named as Morbus Basedow since 1858. In 1854 he pricked in his finger in the postmortem room when examining a patient who had died of typhus and he succumbed to septicemia at the early age of fifty-five. The date of his death was April 11, 1854. On April 14, he was laid in the Sixtus Cemetery in Merseburg. Basedow postulated that a wrong mixing of the blood manifested in cell tissue congestion and glandular vegetation cause the manifestations of disease. If we abstract our modern knowledge and accept circulating antibodies and disturbance of the immune balance as a dyscrasia as well as the proliferation of lymphocytic clones and local cellulary infiltration in terms of immune thyroiditis and autoimmune orbitopathy as cell tissue congestion and glandular vegetations, then doubt arise whether we have indeed made much progress in the last 150 years. At least, respect for the genius of the general physician Carl Adolph von Basedow is becoming greater. We may all hope that in the contributions and the discussions, we shall learn where we stand at the end of

    We examine various integration schemes for the time-dependent Kohn-Sham equations. Contrary to the time-dependent Schrödinger's equation, this set of equations is nonlinear, due to the dependence of the Hamiltonian on the electronic density. We discuss some of their exact properties, and in particular their symplectic structure. Four different families of propagators are considered, specifically the linear multistep, Runge-Kutta, exponential Runge-Kutta, and the commutator-free Magnus schemes. These have been chosen because they have been largely ignored in the past for time-dependent electronic structure calculations. The performance is analyzed in terms of cost-versus-accuracy. The clear winner, in terms of robustness, simplicity, and efficiency is a simplified version of a fourth-order commutator-free Magnus integrator. However, in some specific cases, other propagators, such as some implicit versions of the multistep methods, may be useful.

    Full Text Available In the last years, higher education teacher training has received more didactic-pedagogical attention. Despite numerous criticisms to professors' work, some practices present differentials that make them a reference to students, even among university professors with undergraduate and graduate degrees in their specific areas of knowledge. To analyze the classes of such professors who become a reference to students, we selected two higher education professors of chemistry and videotaped their classes seeking to identify the teaching strategies that they use. After analysis, we shared the results with the subjects and complemented them with a semi-structured interview. We found out that these professors perform based on counter-models of professors who they had had in their undergraduate courses and developed strategies aiming to minimize for their students the difficulties they themselves had experienced.

  5. Economic vs. juristic thinking in Carl Menger’s principles of economics

    Full Text Available Austrian Economic School is increasingly being treated as one of the most significant and ever more influential bodies of ideas affecting the contemporary economic science. It is well known that Carl Menger, the founder of the Austrian School, was a lawyer by education. The paper is devoted to the degree to which his legal education influenced his economic theorizing. After a close examination of the Menger’s conceptual apparatus and the epistemological ramifications of the key notions underlying his thinking, the paper concludes that the juristic background of the far-reaching theoretical contributions contained in Menger’s Principles was truly decisive. That holds true despite the fact that Menger only exceptionally utilized the juristic vocabulary. The key ingredients of his theoretical creation? such as the individual autonomy, the coincidence of the wills in concluding a contract the effective protection of property and making transactions based on the individual motivation to further one’s own interests to the utmost? are clearly inspired and in many ways influenced by private law, particularly the doctrines underlying the Roman Law and the Austrian Civil Code.

  6. [Carl Friedrich von Weizsäcker's language, rhetoric and habitus].

    2014-01-01

    Carl Friedrich von Weizsäcker was not only an exceptional physicist, philosopher and peace scholar, but also a skilled and articulate speaker and a highly successful author. Dozens of his books were published in tens of thousands of copies despite their highly nontrivial content. This wide impact was only possible--this at least is one of the claims made in this paper--because of his sophisticated style and rhetorics. The analysis here is based on hand-picked samples from all kinds of Weizsäcker texts (talks, scientific and popular papers and books, poems and Limericks). Strangely enough, this interesting stylistic and rhetorical facet of his oeuvre has hitherto not been analyzed in any detail despite its crucial importance in the broad impact on his multifarious audience. My paper starts out from a collection of striking features of his language and structural specialties in his published talks and speeches, and explore findings from sound recordings and film tapes which offer further insight into his manner of emphasis, usage of pauses and intonation. On the basis of these stylistic traits and their often subcutaneous, but nevertheless clever rhetorics, I close with a few remarks on the habitus of this scholar and his positioning within the ensemble of German-speaking physicists of that generation.

  7. "Forgotten" Chapters in the History of Transcervical Sterilization: Carl Clauberg and Hans-Joachim Lindemann.

    Transcervical sterilization is a non-surgical method of permanent female sterilization that is widely used and critically discussed. A review of the historiography of the method reveals that instances of its coercive use are not included in the historical account. This study offers a reexamination of the work of Carl Clauberg and Hans-Joachim Lindemann, to more deeply contextualize within the framework of current usage the coercive use of transcervical sterilization during the Third Reich and in postwar Germany. This inquiry is based on postwar criminal trial records on Clauberg, and on archival documents detailing Lindemann's activities in 1979. A comparative analysis examines arguments by medical historian Karl-Heinz Roth, and identifies shared characteristics and differences between Clauberg and Lindemann, their methods and scientific connections. The results demonstrate that the technique of transcervical sterilization has an abusive potential that may be explained as a function of the person of the physician, of the scientific method itself, and of societal and political influences. The analysis supports the argument that insights from the cases of Clauberg and Lindemann are transferrable geographically and over time, and have the potential to inform current medical practice, such as transcervical sterilization with the Essure device, whose historiographic exploration remains a desideratum. © The Author 2017.

  8. Power and Law in Enlightened Absolutism – Carl Gottlieb Svarez’ Theoretical and Practical Approach

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available The term Enlightened Absolutism reflects a certain tension between its two components. This tension is in a way a continuation of the dichotomy between power on one hand and law on the other. The present paper shall provide an analysis of these two concepts from the perspective of Carl Gottlieb Svarez, who, in his position as a high-ranking Prussian civil servant and legal reformist, had unparalleled influence on the legislative history of the Prussian states towards the end of the 18th century. Working side-by-side with Johann Heinrich Casimir von Carmer, who held the post of Prussian minister of justice from 1779 to 1798, Svarez was able to make use of his talent for reforming and legislating. From 1780 to 1794 he was primarily responsible for the elaboration of the codification of the Prussian private law – the »Allgemeines Landrecht für die Preußischen Staaten« in 1794. In the present paper, Svarez’ approach to the relation between law and power shall be analysed on two different levels. Firstly, on a theoretical level, the reformist’s thoughts and reflections as laid down in his numerous works, papers and memorandums, shall be discussed. Secondly, on a practical level, the question of the extent to which he implemented his ideas in Prussian legal reality shall be explored.

  9. Carl Friedrich von Weizsäcker major texts in physics

    CERN Document Server

    2014-01-01

    This book presents a collection of texts by the German physicist and philosopher Carl Friedrich von Weizsäcker (1912-2007), for use in seminars on the history, epistemology and structure of physics. Most texts appear in English for the first time. Weizsäcker became famous through his works in physics, mainly in the early development of nuclear physics. Later he would also become well known as a philosopher and analyst of contemporary culture. Texts include the original publications of the “Weizsäcker-Bethe formula” of nuclear masses and the “Bethe-Weizsäcker cycle,” which explains the source of energy in the sun; both were developed by Bethe at the same time and independently of Weizsäcker. Further texts deal with Weizsäcker’s explanation of the origin of planets, his explanation of the “time arrow” in Statistical Mechanics and his analyses of Quantum Mechanics and the structure of physics in general.

    of examination lawyers and tenders, existing today a new vision called "legal education crisis" in Brazil. According to Carl Rogers (1972, the main role of the teacher is not only to teach but to help the student to learn. This idea has been legitimized internationally since the publication of the UNESCO Report (Delors, 1998, when it pointed out that "learning to know" constitutes one of the pillars of contemporary education. Rogers (1972, in the 1960s,  drew up a list of 10 assumptions implicit deeply rooted among teachers, paradigms that should be addressed by teachers The methodology used was literature and documents with a qualitative approach in the case like an argument from Case Study, considering the Master in Law and the experiences of the Monitoring and Group Study Program. It concludes that the critical evaluation is important in the formation of the legal profession, because the legal education needs to renew itself, from a teaching practice centered learning.

    Carl Rogers' 1957 paper (see record 2007-14639-002) is arguably the most successful of his many attempts to clarify and render testable the ideas behind client-centered therapy. While each of the conditions that Rogers postulated has been linked to positive therapeutic outcome, taken together they have never been conclusively proved (nor disproved) to be either necessary or sufficient for positive outcome. Nevertheless, the overriding "take-home" message in this classic paper--that the therapist's attitude and caring presence is critical for therapeutic success--is one that has had virtually unparalleled influence in every segment of the psychotherapeutic community. Clinical and theoretical innovations in the psychoanalytic community serve as examples of the following proposition: that Rogers' concepts, while accepted more than ever by a remarkably wide variety of psychotherapists, remain essentially unacknowledged as originating with him or in the tradition of humanistic and client-centered therapy.

    Faculty members are viewed as nurturers within the academic setting and may be able to influence students' behaviors through the formation of positive interpersonal relationships. Faculty members' attributes that best facilitated positive interpersonal relationships according to Carl Rogers' Person-Centered Model was studied. Students (n = 192) enrolled in a 3-year undergraduate nursing program in urban Jamaica were randomly selected to participate in this descriptive cross-sectional study. A 38-item questionnaire on interpersonal relationships with nursing faculty and students' perceptions of their teachers was utilized to collect data. Factor analysis was used to create factors of realness, prizing, and empathetic understanding. Multiple linear regression analysis on the interaction of the 3 factors and interpersonal relationship scores was performed while controlling for nursing students' study year and age. One hundred sixty-five students (mean age: 23.18 ± 4.51years; 99% female) responded. The regression model explained over 46% of the variance. Realness (β = 0.50, P < .001) was the only significant predictor of the interpersonal relationship scores assigned by the nursing students. Of the total number of respondents, 99 students (60%) reported satisfaction with the interpersonal relationships shared with faculty. Nursing students' perception of faculty members' realness appeared to be the most significant attribute in fostering positive interpersonal relationships. Copyright © 2015 Elsevier Inc.

    2015-11-25

    The LED lighting retrofit at the Carl Icahn Laboratory of the Lewis-Sigler Institute for Integrative Genomics was the first building-wide interior LED project at Princeton University, following the University’s experiences from several years of exterior and small-scale interior LED implementation projects. The project addressed three luminaire types – recessed 2x2 troffers, cove and other luminaires using linear T8 fluorescent lamps, and CFL downlights - which combined accounted for over 564,000 kWh of annual energy, over 90% of the lighting energy used in the facility. The Princeton Facilities Engineering staff used a thorough process of evaluating product alternatives before selecting an acceptable LED retrofit solution for each luminaire type. Overall, 815 2x2 luminaires, 550 linear fluorescent luminaires, and 240 downlights were converted to LED as part of this project. Based solely on the reductions in wattage in converting from the incumbent fluorescent lamps to LED retrofit kits, the annual energy savings from the project was over 190,000 kWh, a savings of 37%. An additional 125,000 kWh of energy savings is expected from the implementation of occupancy and task-tuning control solutions, which will bring the total savings for the project to 62%.

  14. A New Option for the Reconstruction of Primary or Recurrent Ischial Pressure Sores: Hamstring-Adductor Magnus Muscle Advancement Flap and Direct Closure.

    Owing to the high recurrence rates of ischial pressure sores, surgeons should consider the possibility of future secondary flap surgery during flap selection. The purpose of this article is to present a new surgical option for the reconstruction of primary or recurrent ischial pressure sores using a simple hamstring-adductor magnus advancement flap and direct closure. After horizontal fusiform skin excision, complete bursa excision and ischiectomy were performed. The tenomuscular origin of the adductor magnus and the conjoined tenomuscular origin of the biceps femoris long head and semitendinosus were isolated and completely detached from the inferior border of the ischial tuberosity. They were then advanced in a cephalad direction without detachment of the distal tendon or muscle and securely affixed to the sacrotuberous ligament. The wound was directly closed without further incision or dissection. Twelve ischial pressure sores (6 primary and 6 recurrent; 12 patients) were surgically corrected. The follow-up period was 12 to 65 months. All patients healed successfully without early postoperative complications, such as hematoma, seroma, infection, wound dehiscence, or partial necrosis. Late complications included wound disruption 5 weeks after surgery that spontaneously healed in 1 case and recurrence 3 years later in another case. The new surgical option presented herein, which involves hamstring-adductor magnus advancement flap and direct closure, is a simple and reliable method for providing sufficient muscle bulk to fill the dead space and proper padding to the bone stump while preserving the main vascular perforators and pedicles as well as future surgical options.

  15. Professor Gender, Age, and “Hotness” in Influencing College Students’ Generation and Interpretation of Professor Ratings

    2016-09-01

    Full Text Available Undergraduate psychology students rated expectations of a bogus professor (randomly designated a man or woman and hot versus not hot based on an online rating and sample comments as found on RateMyProfessors.com (RMP. Five professor qualities were derived using principal components analysis (PCA: dedication, attractiveness, enhancement, fairness, and clarity. Participants rated current psychology professors on the same qualities. Current professors were divided based on gender (man or woman, age (under 35 or 35 and older, and attractiveness (at or below the median or above the median. Using multivariate analysis of covariance (MANCOVA, students expected hot professors to be more attractive but lower in clarity. They rated current professors as lowest in clarity when a man and 35 or older. Current professors were rated significantly lower in dedication, enhancement, fairness, and clarity when rated at or below the median on attractiveness. Results, with previous research, suggest numerous factors, largely out of professors’ control, influencing how students interpret and create professor ratings. Caution is therefore warranted in using online ratings to select courses or make hiring and promotion decisions.

    Full Text Available Academics who hold positions at single-mode, distance education institutions are presently being hampered by an adherence to a long-standing set of protocols (specific office location, face-to-face meetings that were put in place when the conventional post-secondary was the norm. With the advent of a powerful merging of personal computers and the internet, a shift from those protocols to one of support for the virtual professor is in the offing, to the benefit of both the professoriate and the student. A key factor in this shift is the degree and quality of institutional support that will allow these changes to take place. This paper focuses on a number of the key factors that will have to be addressed if this new type of distance education academic is to function effectively.

    This interview with Professor Dr. Daniel Spreng of the Center for Energy Policy and Economics (CEPE) in Zuerich, Switzerland, deals with questions concerning research in the area of energy economics. In particular, the situation in Switzerland, where mains-connected sources of energy such as electricity and gas play an important role in energy supply, is looked at in the light of market liberalisation. Various approaches to the liberalisation of gas and electricity systems are discussed and the costs of liberalised supply systems are compared with those of the present monopolistic situation. Also, energy reserves and the use of the gas distribution system in a future hydrogen-based energy supply scenario are looked at. Projects currently being worked on at the CEPE are reviewed

    It is with great sadness that we report the death of Jan Evetts, who lost his second battle with cancer on 18 August 2005. In 1988 he was appointed Founding Editor of this journal where his leadership created the foundation upon which its success rests today. He made an outstanding series of contributions to the science of superconductivity and to the understanding of superconducting materials, and was an indefatigable champion of the development of applications of superconductivity. The loss to the scientific community is incalculable, as is attested by the many communications received from colleagues throughout the world. Professor Jan Edgar Evetts (1939-2005) Professor Jan Edgar Evetts (1939-2005) Jan was born on 31 March 1939, and attended the Dragon School in Oxford, and later Haileybury. He was awarded an exhibition to read Natural Sciences at Pembroke College, Cambridge in 1958 and took his BA degree in 1961. He then undertook a Certificate of Postgraduate Study in Physics under the supervision of Professor Neville Mott. He was the first student to undertake this newly-instituted course; the title of his thesis was `The Resistance of Transition Metals'. In 1962 he joined David Dew-Hughes' embryonic superconducting materials research group, along with Archie Campbell and Anant Narlikar. In fact it was Jan's enthusiasm for the proposed course of research that helped convince David that he should follow Professor Alan Cottrell's suggestion to apply metallurgical methodology to the study of the factors that controlled critical current density in the type II superconductors that were then under development for applications in magnets. Competing theories for the critical current density at that time were fine filaments or `Mendelssohn Sponge' versus the pinning of Abrikosov quantized vortices. The results of the group's work, to which Jan made a major contribution, came down heavily in favour of the latter theory. Jan's outstanding characteristic was his

    Carl Friedrich von Weizsäcker's comprehensive contributions to nuclear disarmament and arms control, as well as his peace policy impulses are to be understood primarily in the context of his family origin, his comprehensive thinking and the historical circumstances of the emerging nuclear age. They have a scientific, political and a strong philosophical-moral component. Beside the factual problems (nuclear energy, military strategy) he was interested in political power issues and their ambivalence and perception. His actual work is not only based on general academic knowledge, but also serve the immediate political influence on a scientific basis. Weizsäcker was not committed to nuclear disarmament or arms control per se, but about creating a lasting peace policy in the nuclear age. The paper discusses in chronological order of Weizsäcker's work within the policy field peace and disarmament. Family origin, study and work on the nuclear programme by Nazi-Germany laid the foundations for his later career. As a young physicist, he was directly involved in the political and ethical dilemma of the military and civilian use of nuclear energy. After the war, in Göttingen and Hamburg the reflections of the Nazi phase and the discussion of ways out of the dangers of the Cold War followed. The Max-Planck Institute in Starnberg dealt with the science-based treatment of global world problems, including the dangers of nuclear proliferation. Finally, Weizsäcker initiated a Peace Council in 1985. He urged both the perception of the moral responsibility of scientists as well as an ethics of the scientific-technological age. According to him, a general and profound change in the consciousness of humankind is needed to solve the existing power problems and the problem of war.

    2004-02-01

    German schools and faculties of veterinary medicine did not receive the sovereign right to award the degree "Doctor medicinae veterinarae" until the early twentieth century. Until then, in the nineteenth century there were two possibilities for veterinarians to earn a doctoral degree, usually referred to as the title of "Doctor": 1. On the basis of an exceptionally excellent dissertation and after very stringent examination a candidate could be awarded the degree "Dr. med." by the faculty of a medical school, or, if the candidate had studied at a philosophical faculty, the degree "Dr. phil." 2. A doctoral degree specifically in veterinary medicine could be earned only at a medical faculty. The Medical Faculty of the University of Giessen awarded the degree "Doctor in arte veterinaria" for the first time in 1832. In this study we prove that Giessen was not the first German university to award a doctorate in veterinary medicine, a priority which has never been questioned in the literature. As early as 1829, veterinarians could earn the degree "Doctor artis veterinariae" at the Medical Faculty of the University of Rostock, where three such awards are documented between 1829 and 1831. The designation "medicina" was also intially avoided in Rostock. Therefore, of particular significance is the discovery of a fourth such document from the Rostock University Archives, the doctoral diploma of Carl Jacob Friedrich Gillmeister, who at the age of 22 was awarded the degree "Doctor medicinae veterinariae" in Rostock after a successful defense. This is the earliest, but also the last archival record of the German doctoral degree in veterinary medicine in the modern sense, because after Gillmeister no veterinarian could earn a doctoral degree in Rostock further more. Gillmeisters vita sheds light on the times and the difficulties of the veterinary profession in the poor agricultural area of Mecklenburg.

  16. Psyche=singularity: A comparison of Carl Jung's transpersonal psychology and Leonard Susskind's holographic string theory

    Science.gov (United States)

    Desmond, Timothy

    In this dissertation I discern what Carl Jung calls the mandala image of the ultimate archetype of unity underlying and structuring cosmos and psyche by pointing out parallels between his transpersonal psychology and Stanford physicist Leonard Susskind's string theory. Despite his atheistic, materialistically reductionist interpretation of it, I demonstrate how Susskind's string theory of holographic information conservation at the event horizons of black holes, and the cosmic horizon of the universe, corroborates the following four topics about which Jung wrote: (1) his near-death experience of the cosmic horizon after a heart attack in 1944; ( 2) his equation relating psychic energy to mass, "Psyche=highest intensity in the smallest space" (1997, 162), which I translate into the equation, Psyche=Singularity; (3) his theory that the mandala, a circle or sphere with a central point, is the symbolic image of the ultimate archetype of unity through the union of opposites, which structures both cosmos and psyche, and which rises spontaneously from the collective unconscious to compensate a conscious mind torn by irreconcilable demands (1989, 334-335, 396-397); and (4) his theory of synchronicity. I argue that Susskind's inside-out black hole model of our Big Bang universe forms a geometrically perfect mandala: a central Singularity encompassed by a two-dimensional sphere which serves as a universal memory bank. Moreover, in precise fulfillment of Jung's theory, Susskind used that mandala to reconcile the notoriously incommensurable paradigms of general relativity and quantum mechanics, providing in the process a mathematically plausible explanation for Jung's near-death experience of his past, present, and future life simultaneously at the cosmic horizon. Finally, Susskind's theory also provides a plausible cosmological model to explain Jung's theory of synchronicity--meaningful coincidences may be tied together by strings at the cosmic horizon, from which they

    Full Text Available Analisamos a relação de Carl Rogers com a Fenomenologia segundo uma perspectiva historiográfica que examina a ocorrência de citações e referências que ele fez a filósofos de orientação fenomenológica. As obras de Rogers foram organizadas em ordem cronológica de publicação e lidas conforme as técnicas de leitura seletiva e interpretativa. Rogers mencionou cinco filósofos de orientação fenomenológica: José Ortega y Gasset, Paul Tillich, Simone de Beauvoir, Maurice Merleau-Ponty e Martin Heidegger. Destes, somente Heidegger é efetivamente trabalhado em um texto sobre o ensino e os demais filósofos procedem de indicações e citações de outros autores. Nos livros em que Rogers referencia esses filósofos não há nenhuma discussão sobre a Fenomenologia; porém, há textos em que Rogers disserta sobre a Fenomenologia sem citar fenomenólogos. A Fenomenologia que Rogers menciona não é a filosófica, a qual ele teve ressalvas, mas é um paradigma estadunidense de ciência empírica e estudos da personalidade. A despeito disso, desenvolve-se no Brasil um movimento pós-rogeriano de orientação filosófica fenomenológica. Ponderamos, finalmente, algumas observações sobre o que distingue o movimento brasileiro daquele paradigma contatado por Rogers nos EUA.

  20. Memories of Professor Sugimoto and isotope separator

    International Nuclear Information System (INIS)

    Tanaka, Kazuhiro

    2013-01-01

    Usual magnetic isotope-separators select the particles with the same Z/A value which may include different nuclides. Identification of the isotope with the same Z/A value but different Z or A value is an universal requirement for nuclear physics experiments. If one knows, together with the A/Z value, the dE/dx or the range of the isotope in some energy absorber, which are the function of Z 2 /A, its nuclide can be specified. This idea can be realized by arranging proper energy-absorber at the focal point of magnetic analyzer. The author proposes another novel method in which two dipole-magnets are excited with some difference, and an energy absorber corresponding to that energy difference is situated between two magnets. It can also be devised so that the dispersion at the final focal-point depends only on the emission angle of the isotope at production. Professor Sugimoto recognized the significance of this scheme and proposed to employ it in the experiment at BEVATRON. The unbalanced two dipole-magnets method is employed at RIKEN and RCNP, Osaka University. The author's creative idea originated in Sugimoto Laboratory at Osaka University. (author)

    2006-03-01

    A few days before the beginning of the 7th European Conference on Applied Superconductivity we learned that Professor Jan Evetts, a pioneer of superconductor research, a brilliant scientist, a wonderful person and a great personal friend, had passed away. We therefore decided to dedicate the 7th European Conference on Applied Superconductivity to the memory of Jan Evetts. The following citation is based on material provided by his former supervisor (D Dew-Hughes) and his closest co-workers in Cambridge. Professor Jan Edgar Evetts (1939-2005) Professor Jan Edgar Evetts (1939-2005) Jan Evetts passed away after losing his second battle with cancer on 24th August 2005. He made an outstanding series of contributions to the science of superconductivity and to the understanding of superconducting materials and was an indefatigable champion of the development of applications of superconductivity. The loss to the superconductivity community is incalculable, as attested by the many communications received from colleagues throughout the world. Jan was born on 31 March 1939, and attended the Dragon School in Oxford, and later Haileybury. He was awarded an exhibition to read Natural Sciences at Pembroke College, Cambridge. He entered the college in 1958 and took his BA degree in 1961. He then undertook a Certificate of Postgraduate Study in Physics under the supervision of Professor Neville Mott. He was the first student to undertake this newly-instituted course; the title of his thesis was `The Resistance of Transition Metals'. In 1962 he joined David Dew-Hughes' superconducting materials research group, along with Archie Campbell and Anant Narlikar. In fact it was Jan's enthusiasm for the proposed course of research that helped convince David that he should follow Professor Alan Cottrell's suggestion to apply metallurgical methodology to the study of the factors that controlled critical current density in the type II superconductors that were then under development for

  2. [Sigmund Freud, Rudolf Meringer and Carl Mayer: slips of the tongue and mis-readings. The history of a controversy].

    Science.gov (United States)

    Hinterhuber, Hartmann

    2007-01-01

    In both his The Psychopathology of Everyday Life and his Lectures Sigmund Freud derived the terms unconscious, preconscious and conscious, particularly from slips in speech, slips in reading and forgetfulness. In these slips, Freud recognised parallels to dreams. In the work mentioned, he analysed these in depth as part of mental motivation. In the papers referred to, Sigmund Freud paid tribute to Rudolf Meringer and Carl Mayer's study which was published in 1895. Meringer and Mayer showed as phenomena reversals and rearrangement of whole words, syllables or sounds, along with pre-tones or anticipations and echoes, word contaminations and word substitutions as responsible for slips of the tongue. The present work demonstrates how passionately these three scientists have contributed to the controversy of their standpoints. For modern psycholinguistics and the psychology of language, speech errors are always an expression of a momentary malfunction of the human speech production system: for the cognitive process of speech production slips of the tongue offer an insight into speech processing. Pre-tones and echoes, serialization errors, as Meringer and Mayer recognised, represent the vast majority of slips of the tongue. They do not reveal any hidden point. But with lexical-semantic slips of the tongue the question of mental motivation is admissible. This short paper is a sign of appreciation and gratitude: firstly, a modest birthday gift for Sigmund Freud, secondly homage to Carl Mayer, who influenced generations of neurologists in his 40 years of chairing the Psychiatric-Neurological Clinic in Innsbruck, so that Hans Ganner rightly spoke of a "Carl Mayer School". But lastly, this short study is also-and especially-a late recognition of Rudolf Meringer, the great Austrian linguist. The view an individual has concerning mental processes and the "topology of the psychic apparatus" is decisive as to the power of determination attached to the unconscious.

  3. Otto Rank, the Rankian circle in Philadelphia, and the origins of Carl Rogers' person-centered psychotherapy.

    deCarvalho, R J

    1999-05-01

    Otto Rank's will therapy helped shape the ideas and techniques of relationship therapy developed by the Philadelphia social workers Jessie Taft, Virginia Robinson, and Frederick Allen in the 1930s. Rank's work and these ideas and techniques in turn strongly influenced the formulation of Carl Rogers' person-centered psychotherapy. This article compares and contrasts will, relationship, and person-centered approaches to psychotherapy and discusses the social factors--primarily the professional conflicts between a male-dominated psychiatry and female social workers over the independent practice of psychotherapy--that were crucial in the dissemination of Rank's psychological thought and the early popularity of Rogers.

    2011-01-01

    In the 1940s, interviewing practice in sociology became decisively influenced by techniques that had originally been developed by researchers in other disciplines working within a number of therapeutic or quasi-therapeutic contexts, in particular the "nondirective interviewing" methods developed by Carl Rogers and the interviewing procedures developed during the Hawthorne studies. This article discusses the development of nondirective interviewing and looks at how in the 1930s and '40s the approach came to be used in sociology. It examines the factors leading to both the popularity of the method and its subsequent fall from favor. © 2011 Wiley Periodicals, Inc.

    Abstract Professor Stuart A. Lipton Stuart A. Lipton, M.D., Ph.D. is recognized here as a Redox Pioneer because of his publication of four articles that have been cited more than 1000 times, and 96 reports which have been cited more than 100 times. In the redox field, Dr. Lipton is best known for his work on the regulation by S-nitrosylation of the NMDA-subtype of neuronal glutamate receptor, which provided early evidence for in situ regulation of protein activity by S-nitrosylation and a prototypic model of allosteric control by this post-translational modification. Over the past several years, Lipton's group has pioneered the discovery of aberrant protein nitrosylation that may contribute to a number of neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (Lou Gehrig's disease). In particular, the phenotypic effects of rare genetic mutations may be understood to be enhanced or mimicked by nitrosative (and oxidative) modifications of cysteines and thereby help explain common sporadic forms of disease. Thus, Lipton has contributed in a major way to the understanding that nitrosative stress may result from modifications of specific proteins and may operate in conjunction with genetic mutation to create disease phenotype. Lipton (collaborating with Jonathan S. Stamler) has also employed the concept of targeted S-nitrosylation to produce novel neuroprotective drugs that act at allosteric sites in the NMDA receptor. Lipton has won a number of awards, including the Ernst Jung Prize in Medicine, and is an elected fellow of the AAAS. Antioxid. Redox Signal. 19, 757–764. PMID:23815466

    2005-06-01

    This dissertation deals with Ellen Gleditsch and some important aspects of her career, as professor, radiochemist and mentor. As Professor Gleditsch supervised students, gave lectures, disseminated science, did research and administrative work; together with many others she participated in the shaping of a research university which developed during her career. She also experienced the daily life in an institute in which there was competition for both resources and positions, included the professorship she was finally granted after many set-backs. The Radiochemist Ellen Gleditsch worked and researched at Marie Curie's laboratory in Paris, and later at Bertram Boltwood's laboratory in New Haven and Stefan Meyer's Institute for Radium Research in Vienna, furthermore she planned and made efforts to establish a similar laboratory in Oslo. During her time in Paris and U.S.A. Gleditsch participated in important debates in the early period of radioactivity, including those on the determination of the radium-uranium ratio and the half-life of radium. In Norway she devoted her time to atomic weight determinations, age determinations, and radiogeological investigations. Research was all important part of Gleditsch's life and career. Gleditsch was also a Mentor in many respects; in tile international radioactivity community, as one of the first female academics and radiochcmists in Norway, for her many students, and this role seems also to have been hers within her family. In Paris she looked after students from all over the world to help alleviate their home sickness, at the University of Oslo she was known as the scientific mother to many; mentoring was among Gleditsch's main qualities. The story of Ellen Gleditsch opens for several perspectives that are discussed. 3 papers are included. In paper 1, ''Ellen Gleditsch: Pioneer Woman in Radiochemistry'', the story is about the young chemist Ellen Gleditsch, who arrived in Paris in 1907 and started cooperating with Marie Curie

    2014-10-01

    Full Text Available The article offers an analysis of the linguocultural character type professor taking into consideration both traditional set of signs and those transformations that indicate accumulation of evolutionary changes. The methodological base for the systematic description were the achievements of such areas of scientific knowledge as personology, linguopersonology and discourseology. The linguocultural character type (LCCT is a generalised image of persons, whose behaviour and value orientations influence culture, language and show social originality of the society. The peculiarity of the studied linguocultural character type is in its interrelation with the linguocultural character types intellectual and teacher as well as in the fact of the traditional connection with the concept elite. The exposure of such kind of multidimensional relations allowed to focus attention on the qualities of the LCCT professor that ensure its relative self-sufficiency. The sign of elitism and belonging to the intellectuals of the LCCT professor is asserted by the high social status recognised by the society, which is based on professionalism and compliance with moral principles. The axiological generality of the LCCT professor and teacher is ensured by the peculiarities of the modern pedagogical discourse with its typical image settings. One of the main features of the image of a professor is its belonging to the elite language person. The transformational processes in the contents of the LCCT professor are connected with the globalisation: including the international dimension in the evaluation of the professional activity, complication of the language environment, marketisation of the university sphere.

    Directory of Open Access Journals (Sweden)

    Dae Seung Cho

    2016-03-01

    Full Text Available In this paper, a numerical procedure for the natural vibration analysis of plates with openings and carlings based on the assumed mode method is extended to assess their forced response. Firstly, natural response of plates with openings and carlings is calculated from the eigenvalue equation derived by using Lagrange's equation of motion. Secondly, the mode superposition method is applied to determine frequency response. Mindlin theory is adopted for plate modelling and the effect of openings is taken into account by subtracting their potential and kinetic energies from the corresponding plate energies. Natural and frequency response of plates with openings and carlings subjected to point excitation force and enforced acceleration at boundaries, respectively, is analysed by using developed in-house code. For the validation of the developed method and the code, extensive numerical results, related to plates with different opening shape, carlings and boundary conditions, are compared with numerical data from the relevant literature and with finite element solutions obtained by general finite element tool.

    2000-07-01

    The authors conducted a biomechanical study in which they compared the uses of the Rogers interspinous and the Lovely-Carl tension band wiring techniques for internal fixation of the cervical spine. An extensive biomechanical evaluation (stiffness in positive and negative rotations around the x, y, and z axes; range of motion in flexion-extension, bilateral axial rotation, and bilateral bending; and neutral zone in flexion-extension, bilateral axial rotation, and lateral bending to the right and to the left) was performed in two groups of intact calf cervical spines. After these initial tests, all specimens were subjected to a distractive flexion Stage 3 ligamentous lesion. Group 1 specimens then underwent surgical fixation by the Rogers technique, and Group 2 specimens underwent surgery by using the Lovely-Carl technique. After fixation, specimens were again submitted to the same biomechanical evaluation. The percentage increase or decrease between the pre- and postoperative parameters was calculated. These values were considered quantitative indicators of the efficacy of the techniques, and the efficacy of the two techniques was compared. Analysis of the findings demonstrated that in the spines treated with the Lovely-Carl technique less restriction of movement was produced without affecting stiffness, compared with those treated with the Rogers technique, thus making the Lovely-Carl technique clinically less useful.

    The painless needle insertion technique, summarized by Professor WU Lian-zhong during his decades of acupuncture clinical practice is introduced in this article, which is characterized as soft, flexible, fast, plucking and activating antipathogenic qi. The Sancai (three layers) lifting and thrusting manipulation technique is adopted by Professor WU for getting the qi sensation. And features of 10 kinds of needling sensation such as soreness, numbness, heaviness, distension, pain, cold, hot, radiation, jumping and contracture are summarized. Finger force, amplitude, speed and time length are also taken as the basis of reinforcing and reducing manipulations. Moreover, examples are also given to explain the needling technique on some specific points which further embodies Professor WU's unique experiences and understandings on acupuncture.

    2018-05-01

    Teamwork is increasingly seen as an important component of engineering education programmes. Yet, prior research has shown that there are numerous ways in which teamwork is gendered, and can lead to negative experiences for women students. This article presents the first interview findings on professors' perspectives on gender and teamwork. Semi-structured interviews were conducted with 39 engineering professors to determine what and how they thought about gender in engineering and engineering education. For this article, the parts of the interviews about teamwork are analysed. We conclude that professors need tools to help them facilitate gender-inclusive teamwork, and those tools must address the beliefs that they already hold about teamwork. The findings raise questions about the adoption of evidence-based instructional practices and suggest current teamwork practices may exacerbate gender inequalities in engineering.

    Professor Kazimierz Jaegermann, a founder of the theory of medico-legal opinionating, passed away 20 years ago. Numerous specialists in forensic medicine and an ever increasing number of lawyers substantiate the importance and value of the creative thought and the entire research work of Professor Jaegermann that have been an inspiration of progress in forensic medicine and in the science of applied law. His unique ability to perform a scientific synthesis leading to recognizing forensic medicine as an applied bridging knowledge points to the eminently creative role played by Professor Jaegermann in development of forensic medicine. There is an urgent need to recall his research activities and to publish a complete collection of his articles and publications. With this idea in mind, I present below an article based on the text published in No. 1 of the Zeszyty Naukowe Katedry Medycyny Sadowej Slaskiej Akademii Medycznej in 1995.

  7. Faculty Agency in Applying for Promotion to Professor

    2017-02-01

    Full Text Available Aim/Purpose: In the United States, faculty who wish to pursue promotion to the rank of professor do so without clear guidance or structure. Even the timing of such a process is nebulous. As such, an individual engages in agentic action to pursue the rank. Background: This study examined the experiences of faculty members who chose to pursue the application process to be promoted to professor but were rejected or dissuaded. Methodology: Utilizing a case study of one institutional setting, we conducted 10 in-depth qualitative interviews. Contribution: Very little is known about the process of promotion to full professor in the U.S. and even less empirical research exists. This study advances knowledge of the process and the experiences of those undertaking it. Findings: We learned that cues from the social context greatly influenced these faculty members’ sense of agency.

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

    From 1970 to 1980 Carl Friedrich von Weizsäcker headed the Max-Planck-lnstitut zur Erforschung der Lebensbedingungen der wissenschaftlich-technischen Welt (MPI for the study of the living conditions of the world of science and technology) in Starnberg, jointly with Jürgen Habermas since 1971. From the start, the Max Planck Society regarded the new institute as an experiment that might perhaps be aborted a few years later. This is exactly what happened. With the retirement of Weizsäcker, his section was closed and the whole institute was renamed. In 1981. Habermas resigned, and then the institute was closed. This paper focusses on some of the problem constellations within the institute that partly explain its development and eventual closure: its birth out of the idea of scientific policy advice, the debates within the Max Planck Society and the complex relationship between Weizsäcker and Jürgen Habermas.

  10. Proses Individuasi Carl Gustav Jung pada Tokoh Erika Kohut dalam Novel Sang Guru Piano Karya Elfriede Jelinek

    Directory of Open Access Journals (Sweden)

    M. Oktavia Vidiyanti

    2007-12-01

    Full Text Available A personality structure that appears in Erika is similar to one of an important part of Carl Gustav Jung psychology. Jung states that personality is a psiko that covers consciousness and unconsciousness. This psiko will develop to be a stable unity. If every system develops in every individual absolutely, so a health and integrated personality will be achieved. That process in Jung is known as a self­ individualized process. The aim of individualism is a self­achievement. Individual is not only as a psiko centre but also as a representation of the whole individual that unites consciousness and unconsciousness. It is like the character "Erika Kohut" in the novel "Sang Guru Piano".

    Longitudinal data involving 106 children and their parents were used to test preschool child-rearing implications of Carl Rogers's theory of creativity-fostering environments (Rogers, 1954). Indices were developed for each parent and for each mother-father combination that reflected the degree to which the parents' child-rearing practices and interactions with their preschool children matched the recommendations implicit in Rogers's description of a creativity-fostering environment. The three indices of Rogers-prescribed child-rearing practices each correlated positively (rs = .38 to .46) and significantly (all ps less than .001) with a composite index of creative potential in early adolescence, 7 to 11 years later. Rogers-prescribed preschool child-rearing practices also emerged as significant antecedents of adolescent creative potential in regression/path analyses that held constant the influence of sex, preschool intelligence, and preschool creative potential. Theoretical and methodological aspects of the study are discussed.

    (1) Quantum theory deals not just with reality but with the physical (scientific) reality of its objects. Carl Friedrich von Weizsäcker understood this to imply that scientific knowledge of objects converges with philosophical knowledge of their objectivity but did not succeed in rounding off physics. (2) We are actors as well as spectators not only in scientific knowledge but in political processes as well, particularly by means of science. It is, therefore, not justified to deny political responsibility even in 'basic research'. Carl Friedrich von Weizsacker identified classical physics as the venture of knowledge without love but believed that this boundary could be transcended. The apparent neutrality of science must not be tolerated by the churches, however. (3) In religion Weizsäcker felt most at home in Buddhist spirituality, this being akin to Christian spirituality which has been more or less lost by the Christian churches. Yet he tried to support his church and to participate in its actions. (4) Lack of love corresponds to an excess of power in the religious critique of science. In both respects Weizsäcker presented the mirror to industrial society but people in general did not recognize their image. The Max-Planck-Society, however, shut up Weizsäcker's "Institute for the study of the conditions of life in the modern world" (Starnberg 1970-1980) as soon as possible. (5) Weizsäcker always refrained from exerting any power except that of reason or truth. According to Lao Tse this is the power least perceived as such. In politics he generally followed the mainstream after once having been tempted to action in 1941/42. His influence on German society was based on his charismatic spirituality.

  13. Kinetic Targeting of pegylated liposomal Doxorubicin: a new Approach to Reduce Toxicity during Chemotherapy (CARL-trial

    Directory of Open Access Journals (Sweden)

    Jansen Martin

    2011-08-01

    Full Text Available Abstract Background The therapeutic success of chemotherapeutic agents is often limited by severe adverse effects. To reduce toxicity of these drugs, nanoscale particle-based drug delivery systems (DDS are used. DDS accumulate to some extent in tumor tissues, but only a very small portion of a given dose reaches this target. Accumulation of DDS in tumor tissues is supposed to be much faster than in certain other tissues in which side effects occur ("Kinetic Targeting". Once saturation in tumor tissue is achieved, most of the administered DDS still circulate in the plasma. The extracorporeal elimination of these circulating nanoparticles would probably reduce toxicity. Methods For the CARL-trial (Controlled Application and Removal of Liposomal chemotherapeutics, pegylated liposomal doxorubicin (PLD was used as chemotherapeutic agent and double filtration plasmapheresis (DFPP was performed for extracorporeal elimination of liposomes. PLD was given as 40 mg/m2 every 3 weeks in combination with vinorelbine 2 × 25 mg/m2 (neoadjuvant treatment of breast cancer, 12 patients, or as 40 mg/m2 every 4 weeks (recurrent ovarian cancer, 3 patients. Primary endpoints were the efficiency and safety profile of DFPP, and secondary endpoints were side effects and tumor response. Results DFPP eliminated ~62% of circulating PLD, corresponding to ~45% of the total dose (n = 57 cycles. AUC of doxorubicin was reduced by 50%. No leakage of doxorubicin was detected during elimination, and no relevant DFPP-related side effects occurred. Reduction in tumor size > 30% occurred in 10/12 (neoadjuvant and in 1/3 patients (recurrent. Only five grade 2 events and one grade 3 event (mucositis, neutropenia or leucopenia and a single palmar-plantar erythrodysesthesia grade 2 were reported. Conclusion Extracorporeal elimination of PLD by DFPP is safe and efficient. CARL can diminish the main dose-limiting side effects of PLD, and probably many different DDS alike. Trial

    Gross, Jennifer; Lakey, Brian; Lucas, Jessica L; LaCross, Ryan; R Plotkowski, Andrea; Winegard, Bo

    2015-01-01

    Background Two important influences on students' evaluations of teaching are relationship and professor effects. Relationship effects reflect unique matches between students and professors such that some professors are unusually effective for some students, but not for others. Professor effects reflect inter-rater agreement that some professors are more effective than others, on average across students. Aims We attempted to forecast students' evaluations of live lectures from brief, video-recorded teaching trailers. Sample Participants were 145 college students (74% female) enrolled in introductory psychology courses at a public university in the Great Lakes region of the United States. Methods Students viewed trailers early in the semester and attended live lectures months later. Because subgroups of students viewed the same professors, statistical analyses could isolate professor and relationship effects. Results Evaluations were influenced strongly by relationship and professor effects, and students' evaluations of live lectures could be forecasted from students' evaluations of teaching trailers. That is, we could forecast the individual students who would respond unusually well to a specific professor (relationship effects). We could also forecast which professors elicited better evaluations in live lectures, on average across students (professor effects). Professors who elicited unusually good evaluations in some students also elicited better memory for lectures in those students. Conclusions It appears possible to forecast relationship and professor effects on teaching evaluations by presenting brief teaching trailers to students. Thus, it might be possible to develop online recommender systems to help match students and professors so that unusually effective teaching emerges. PMID:24953773

MÉTODOS: Participaram 205 indivíduos sendo 105 professores e 100 não professores entre 23 a 65 anos, 106 mulheres e 99 homens. Foi aplicado um questionário contendo quatro perguntas referentes a uma eventual perda de visão, audição, voz e deambulação e o grau de impacto inferido (de 0 a 4. RESULTADOS: Para o grupo de professores, não enxergar gerou o maior impacto negativo (média de 3,8, seguido por não andar (média de 3,7, não ter voz (média de 3,7 e não ouvir (média de 3,6. Para o grupo de não-professores, não enxergar também gerou o maior impacto negativo (média de 3,4, seguido por não andar (média de 3,0; não ouvir (média de 2,2 e não ter voz (média de 2,0. Em relação ao maior impacto de uma eventual perda da voz, professores indicaram prejuízos no trabalho, relacionamento social e atividades rotineiras e, no grupo de não professores, nas atividades rotineiras, trabalho, relacionamento social e manifestações das emoções. CONCLUSÕES: Os professores valorizam sua voz de modo diverso dos não-professores e ambos os grupos avaliam a perda da voz como algo que não acarreta consequências negativas. Apesar de o professor perceber mais o impacto de um eventual problema de voz do que o não-professor, os sentimentos em relação à perda da voz foram muito semelhantes nos dois grupos.PURPOSE: To investigate teachers' and non-teachers' perception regarding the implications of an eventual loss of voice.

  9. Mercury and sulphur among the High Medieval alchemists: from Rāzī and Avicenna to Albertus Magnus and pseudo-Roger Bacon.

    Science.gov (United States)

    Newman, William R

    2014-11-01

    This essay challenges the often expressed view that the principles of metals, namely mercury and sulphur, were generally viewed by alchemists as being of a 'metaphysical' character that made them inaccessible to the tools and operations of the laboratory. By examining a number of Arabo-Latin and Latin alchemical texts in circulation before the end of the thirteenth century, the author presents evidence that most alchemists of the period considered mercury and sulphur to be materials subject to techniques of purification in the same way that naturally occurring salts and minerals could be freed of their impurities or dross. The article also points to the immense influence of Avicenna and Albertus Magnus in formulating the theory that mercury and sulphur were compounds of different materials, containing both fixed and unfixed components. Finally, the author briefly examines the relationship between this materialist approach to the principles and the chymical atomism of early modern authors who were deeply aware of medieval alchemical literature.

    Background People are frequently confronted with untrustworthy claims about the effects of treatments. Uncritical acceptance of these claims can lead to poor, and sometimes dangerous, treatment decisions, and wasted time and money. Resources to help people learn to think critically about treatment claims are scarce, and they are widely scattered. Furthermore, very few learning-resources have been assessed to see if they improve knowledge and behavior. Objectives Our objectives were to develop the Critical thinking and Appraisal Resource Library (CARL). This library was to be in the form of a database containing learning resources for those who are responsible for encouraging critical thinking about treatment claims, and was to be made available online. We wished to include resources for groups we identified as ‘intermediaries’ of knowledge, i.e. teachers of schoolchildren, undergraduates and graduates, for example those teaching evidence-based medicine, or those communicating treatment claims to the public. In selecting resources, we wished to draw particular attention to those resources that had been formally evaluated, for example, by the creators of the resource or independent research groups.

    Directory of Open Access Journals (Sweden)

    Maritza Ceicilia Felices Luna

    2013-09-01

    Full Text Available This article postulates that the study of political violence and armed conflict contributes to critical criminological theory by suggesting to look into Carl Schmitt’s concept of ‘the political’ as an alternative to the more typical conceptualisations of ‘politics’ (i.e. Weberian -power-, Marxist -class struggle- or Foucualdian -domination. It is my contention that the latter dilute politics into the economic, social, cultural sphere given that almost everything can be surmise to be an issue of power, domination or class struggle whereas the former highlights the boundaries of the political realm while still allowing for analytical connections and links to be established with the other spheres of society. The concept of ‘the political’ has opened up new avenues for those working on issues of state crimes, mass atrocities and social harm. Moreover, it can reinvigorate critical criminology’s denunciation of the state, its social control apparatuses (such as the criminal justice system as well as other modes of governance by articulating the destructive character of the criminal justice system and of similar forms of social control.

    This issue includes a special section on computational fluid dynamics (CFD) in memory of the late Professor Kunio Kuwahara, who passed away on 15 September 2008, at the age of 66. In this special section, five articles are included that are based on the lectures and discussions at `The 7th International Nobeyama Workshop on CFD: To the Memory of Professor Kuwahara' held in Tokyo on 23 and 24 September 2009. Professor Kuwahara started his research in fluid dynamics under Professor Imai at the University of Tokyo. His first paper was published in 1969 with the title 'Steady Viscous Flow within Circular Boundary', with Professor Imai. In this paper, he combined theoretical and numerical methods in fluid dynamics. Since that time, he made significant and seminal contributions to computational fluid dynamics. He undertook pioneering numerical studies on the vortex method in 1970s. From then to the early nineties, he developed numerical analyses on a variety of three-dimensional unsteady phenomena of incompressible and compressible fluid flows and/or complex fluid flows using his own supercomputers with academic and industrial co-workers and members of his private research institute, ICFD in Tokyo. In addition, a number of senior and young researchers of fluid mechanics around the world were invited to ICFD and the Nobeyama workshops, which were held near his villa, and they intensively discussed new frontier problems of fluid physics and fluid engineering at Professor Kuwahara's kind hospitality. At the memorial Nobeyama workshop held in 2009, 24 overseas speakers presented their papers, including the talks of Dr J P Boris (Naval Research Laboratory), Dr E S Oran (Naval Research Laboratory), Professor Z J Wang (Iowa State University), Dr M Meinke (RWTH Aachen), Professor K Ghia (University of Cincinnati), Professor U Ghia (University of Cincinnati), Professor F Hussain (University of Houston), Professor M Farge (École Normale Superieure), Professor J Y Yong (National

    As one of the important founders of GAO's acupuncture academic school in YanZhao area, Professor GAO Yuchun 's experience of acupuncture for headache is summarized in this paper. In the opinion of Professor GAO, the treatment of headache should focus on eliminating evil and relieving pain, and the syndrome differentiation should be based on meridian differentiation, especially on three yang meridians of foot as well as liver meridian and kidney meridian. In the acupoint prescription, attention should be placed on strengthening the spleen and stomach. The midnight-midday ebb flow acupuncture is advocated. The combination between acupuncture order and movement of qi is emphasized. In the manipulation, the role of pressing hand, the stimulation during reinforcing and reducing methods, and needle-retention time are important. The breathing reinforcing and reducing method of acupuncture are also advocated.

With deep study of Huangdi Neijing ( The Inner Canon of Huangdi ) and Zhenjiu Dacheng ( Compendium of Acupuncture and Moxibustion ), the author further learned professor ZHANG Jin 's theory and operation specification of "concentrating force into needle body, so the force arriving before and together with needle". The whole-body force should be subtly focused on the tip of needle, and gentle force at tip of needle could get significant reinforcing and reducing effect. In addition, proper timing at tip of needle could start reinforcing and reducing effect, lead qi to disease location, and achieve superior clinical efficacy.

    For the treatment of primary dysmenorrhea, professor ZHAO Jiping focuses on meridian diagnosis and inspection, and uses pressing methods to locate the response points along the meridian, including acupoints and aishi points. During the stage of attack, it is essential to press along the spleen meridian, mainly Sanyinjiao (SP 6), Diji (SP 8) and Yinlingquan (SP 9); during the stage of remission, it is essential to press along the bladder meridian and stomach meridian, mainly Ganshu (BL 18), Pishu (BL 20), Weishu (BL 21), Shenshu (BL 23) and Zusanli (ST 36). The differences between deficiency syndrome and excess syndrome lead to the different feelings of doctors and patients. Combined with the results of meridian diagnosis and inspection, the aim of treatment can be achieved by different acupuncture methods. Professor ZHAO pays attention to the treatment of accompanied symptoms and timing of treatment, since the relief of accompanied syndromes and selection of timing are keys to relieving patient's pain.

Professor YANG focuses on the thinking model that combines TCM, western medicine and acupuncture, and adopts the differentiation system that combines disease differentiation, syndrome differentiation and meridian differentiation; he adopts the treatment integrates etiological treatment, overall regulation, symptomatic treatment as well as acupuncture, moxibustion, medication and flash cupping. The acupoints of yangming meridians are mostly selected, and acupoints of governor vessel such as Dazhui (GV 14) and Jinsuo (GV 8) are highly valued. The multiple-needles shallow-penetration-insertion twirling lifting and thrusting technique are mostly adopted to achieve slow and mild acupuncture sensation; in addition, the facial muscles are pulled up with mechanics action. The intensive stimulation with electroacupuncture is recommended at Qianzheng (Extra), Yifeng (TE 17) and Yangbai (GB 14), which is given two or three treatments per week.

    Directory of Open Access Journals (Sweden)

    José Javier BERMÚDEZ-APONTE

    2017-12-01

    Full Text Available In the first part of this article, the authors explain how the teaching role is affected by certain social and cultural changes, like the knowledge society emergence, the universities orientation towards marketing, the constant demand and pressure exerted on teachers to publish, the loss of the ethical sense in the academic activity and the disparity of tasks that are being assigned to the university professors. In view of the above, a comprehensive model, compound by two concepts –personal and professional– of a university professor is proposed; in fact, this model incorporates and summarises different contributions regarding this theme. Finally, this article aims to defend the need to understand the teaching role as a vocation, in the broadest sense of the word, a vocation carries the inclination to pursue an aim: the education of those students that teachers have in charge.

  18. The University Professor View from the Communitarian Perspective

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available The task of the university professor is a mission and not simply a profession and that is why higher education should be impregnated with values. Nowadays education is articulated into three areas: the State, the Market and the Volunteering, but no one of these three sectors by themselves has covered the needs of all the citizens, there have always been losers, therefore the conjunction of the three sectors became necessary. Communitarianism promotes an ethical-social pact that favors the progress of society without nullifying the individual dimension. It believes that the university is the space where a communitarian consciousness should be promoted to generate a social capital by means of education and it is a privilege place to substantiate the moral identity of the person beginning with the commitment of the professor with the university student.

  19. Professor Peter Higgs: "My Life as a Boson"

    CERN Multimedia

    2012-01-01

    Professor Peter Higgs played a key role in the development of the Standard Model, our current theory of fundamental physics. The search for the Higgs Boson is the centrepiece of the LHC programme at CERN, and the existence of this famously elusive particle is likely to be confirmed or refuted with data currently being collected, using apparatus partly designed at Bristol. Professor Higgs will introduce the ideas of spontaneous symmetry breaking, and discuss how these developed from their application in condensed matter through the earlier work of Yoichiro Nambu and Jeffrey Goldstone, to the work of Robert Brout, Francois Englert and himself in 1964. The subsequent application of these ideas to electroweak theory will be discussed briefly.

  20. Carl Schmitt's attitude towards total war and total enemy on the eve of the outbreak of WWII

    Full Text Available Carl Schmitt is usually perceived as the theorist of total state, total war and total hostility. In the article, the author however tries to show that from 1937 to 1944, Schmitt was arguing that total war and total hostility were dangerous for Germany (as well as for the rest of Europe and warned against perpetuation of all efforts to totalize enemy that started in 1914. In his theoretical endeavors in this period there was place for the total state only - and especially for the total state strong enough to resist temptation of declaring total war on total enemy. The total state he recommended Hitler and his Nazi comrades was German Reich, as a part of Europe ordered and divided in the huge spaces (Grossraumordnung. Positioned in the centre of Europe, between the rest of the powers (France, Italy, USSR as well as the Scandinavian states, Germany should be careful enough to wage war only against its Eastern enemies (Poland and maybe USSR and only in order to achieve 'just' borders. Occupying in this way its huge space Germany should devote itself to the task of exploitation of various peoples such as Poles, Chechs and Slovaks, which were perceived as incapable of having their states and doomed to serve the master race - the Germans.

    We describe similarities in the ontology of quantum physics and of Carl Gustav Jung's psychology. In spite of the fact that physics and psychology are usually considered as unrelated, in the last century, both of these disciplines have led at the same time to revolutionary changes in the Western understanding of the cosmic order, discovering a non-empirical realm of the universe that doesn't consist of material things but of forms. These forms are real, even though they are invisible, because they have the potential to appear in the empirical world and act in it. We present arguments that force us to believe, that the empirical world is an emanation out of a cosmic realm of potentiality, whose forms can appear as physical structures in the external world and as archetypal concepts in our mind. Accordingly, the evolution of life now appears no longer as a process of the adaptation of species to their environment, but as the adaptation of minds to increasingly complex forms that exist in the cosmic potentiality. The cosmic connection means that the human mind is a mystical mind.

    Carl Friedrich von Weizsäcker was a key figure in the history of the Max Planck Society (MPS). This essay contextualises his work with the development of the MPS, highlighting the institutional and personal networks upon which it was based. Some of the stations addressed in the following are his role in the German Uranium Project, in preparing the Mainau Declaration, the Göttingen Manifesto, and the Memorandum of Tübingen as well as his involvement in the foundation of the Max Planck Institute (MPI) for Human Development and his own MPI for the Research of Living Conditions in the Modern World located in Starnberg. The relationship between Weizsäcker and Hellmut Becker, long-time friend and founding director of the MPI for Human Development, will be of particular interest. Another issue broached here is the connection between natural science and the humanities in Weizsäcker's work, and subsequently the relation between these two science cultures in the MPS. Finally, we look at the challenges Weizsäcker's work could present to the MPS today.

    The Carl Gustav Carus Faculty of Medicine, University of Technology Dresden, Germany, was founded in 1993 after the reunification of Germany. In 1999, a reform process of medical education was started together with Harvard Medical International. The traditional teacher and discipline-centred curriculum was replaced by a student-centred, interdisciplinary and integrative curriculum which has been named DIPOL (Dresden Integrative Patient/Problem- Oriented Learning). The reform process was accompanied and supported by a parallel-ongoing Faculty Development Program. In 2004, a Quality Management Program in medical education was implemented, and in 2005 medical education received DIN EN ISO 9001:2000 certification. Quality Management Program and DIN EN ISO 9001:2000 certification were/are unique for the 34 medical schools in Germany. The students played a very important strategic role in all processes. They were/are members in all committees like the Faculty Board, the Board of Study Affairs (with equal representation) and the ongoing audits in the Quality Management Program. Students are the only ones who experience all years of the curriculum and are capable of detecting, for example gaps, overlaps, inconsistencies of the curriculum and assessments. Therefore, the in-depth knowledge of students about the medical school's curriculum is a very helpful and essential tool in curriculum reform processes and Quality Management Programs of medical education. The reform in medical education, the establishment of the Quality Management program and the certification resulted in an improvement of quality and output of medical education and medical research.

  5. Entre Carl Schmitt y Thomas Hobbes . Un es tudio del liberalismo moderno a partir del pensamiento de Leo Strauss

    Directory of Open Access Journals (Sweden)

    José Daniel Parra Quintero

    2010-01-01

    Full Text Available El presente ensayo es una lectura sobre el liberalismo moderno desde el pensamiento de Leo Strauss. A partir de su análisis del Concepto de lo político de Carl Schmitt y su crítica de la "despolitización y neutralización" liberal, Strauss responde con una afirmación del problema del derecho natural, para lo cual es fundamental como primer paso estudiar la filosofía política de Thomas Hobbes. Desde allí Strauss se plantea un punto de contraste hacia una consideración clásica del derecho natural que pueda hacer frente al nihilismo político o cosmopolitanismo apolítico en la modernidad tardía, resultado ambos tanto del histori-cismo radical como del positivismo metodológico. Strauss antepone a la afirmación de la voluntad del poder soberano la búsqueda del derecho natural como representación de la idea de la justicia.

    Jorge C. Restrepo Ramos

    2014-01-01

    Full Text Available El concepto de teología política de Carl Schmitt ha sido leído desde diversas ópticas, usualmente restando importancia al debate que el autor sostiene con Hans Kelsen en torno a las teorías de la soberanía, el Estado y el Derecho. Aquí se propone resaltar ese debate y proponer una lectura de la obra de Schmitt, según la cual el tercer capítulo de Teología política contiene una tesis epistemológica opuesta al purismo kelseniano, cuyo alcance teórico es quizás más rico que una mera repetición de topoi reaccionarios, como lo sugieren las lecturas alternativas. Tras justificar esa lectura, el artículo se ocupa de las características específicas del concepto de teología política esbozado por Schmitt.

    Full Text Available Si Carl Einstein sigue siendo de por sí una figura marginal dentro de la cultura alemana, su obra Die Fabrikation der Fiktionen permanece desatendida incluso entre sus estudiosos pese a contener valiosísimas claves para entender el cruce entre filosofía y política que caracteriza a buena parte del pensamiento europeo del siglo XX. Así las cosas, tras una parte inicial donde se dibuja a grandes rasgos la personalidad del autor y se toma el pulso a sus últimas ideas y acciones, el artículo despliega un examen detenido de la obra, realizando en primera instancia un cotejo de las distintas interpretaciones que de ella se han venido haciendo, y llevando después a cabo una nueva lectura de sus principales ideas fuerza –el conflicto entre Realität y Wirklichkeit o el propio concepto de Fiktion– y una valoración de la empresa einsteiniana mediante su contraste con ciertas obras de pensadores coetáneos como Siegfried Kracauer y Paul Nizan.

    2017-10-01

    Full Text Available O artigo estabelece um diálogo entre as teorias de Carl Schmitt, Walter Benjamin e Giorgio Agamben, transpondo-as para a realidade social brasileira. A naturalização da desigualdade constitui marca cruel de nossa sociedade, e a filosofia do direito contribui para uma abordagem jurídica que leva em conta as disparidades sociais. Far-se-á, primeiramente, uma análise do estado de exceção à luz das obras de Benjamin e Agamben. Posteriormente, com Schmitt, a questão da exceção será analisada em conjunto com a decisão política, demonstrando a ligação intrínseca entre direito e política e o reflexo disto no agravamento das desigualdades sociais. Será estabelecida a diferença entre os conceitos de “inimigo”, de Schmitt, e homo sacer, de Agamben, na instauração do estado de exceção e como o conceito de “inimigo” foi desvirtuado com a construção da Teoria do Direito Penal do Inimigo.

    Full Text Available Today, I want to believe in the old saying that the soul, the spirit of the departed lingers on for a while among the living. I like to believe our homage here today will somehow reach Stelian Petrescu, our professor, colleague, mentor and coworker, who put his passion, talent, love and devotion into serving the chemical engineering school in Iaşi. His life and work have been closely related to our Faculty of Chemical Engineering and Environmental Protection. In 1975, he graduated from the Faculty of Industrial Chemistry of the Polytechnic Institute with a degree in the Technology of Inorganic Substances, and in 1980, he went on to teach at the “Gheorghe Asachi” Technical University in Iaşi, where he gradually built an exceptional career. In 1987, he earned a PhD in chemical engineering, and he became a full professor in 1996. A hard worker and brilliant researcher, Professor Petrescu has published over 15 books and textbooks and over 150 valuable scientific articles. He was also the author of over 40 patents, many of which received awards at international invention fairs. An outstanding member of the group of teachers with the Chemical Engineering Department, which he has run and coordinated for a long time, he has contributed to the education of over 30 generations of engineers and the development of a new generation of doctors in chemical engineering. He was beloved and held in high regard both by his students and his colleagues. Professor Petrescu has left this world prematurely, unexpectedly and unjustly. We will all miss him and will surely remember all the wonderful times we spent together. On behalf of his colleagues and students, I would like to extend my deepest condolences to his family.

  13. Professor Created On-line Biology Laboratory Course

    Bowman, Arthur W.

    2010-01-01

    This paper will share the creation, implementation, and modification of an online college level general biology laboratory course offered for non-science majors as a part of a General Education Curriculum. The ability of professors to develop quality online laboratories will address a growing need in Higher Education as more institutions combine course sections and look for suitable alternative course delivery formats due to declining departmental budgets requiring reductions in staffing, equipment, and supplies. Also, there is an equal or greater need for more professors to develop the ability to create online laboratory experiences because many of the currently available online laboratory course packages from publishers do not always adequately parallel on-campus laboratory courses, or are not as aligned with the companion lecture sections. From a variety of scientific simulation and animation web sites, professors can easily identify material that closely fit the specific needs of their courses, instructional environment, and students that they serve. All too often, on-campus laboratory courses in the sciences provide what are termed confirmation experiences that do NOT allow students to experience science as would be carried out by scientists. Creatively developed online laboratory experiences can often provide the type of authentic investigative experiences that are not possible on-campus due to the time constraints of a typical two-hour, once-per-week-meeting laboratory course. In addition, online laboratory courses can address issues related to the need for students to more easily complete missing laboratory assignments, and to have opportunities to extend introductory exercises into more advanced undertakings where a greater sense of scientific discovery can be experienced. Professors are strongly encourages to begin creating online laboratory exercises for their courses, and to consider issues regarding assessment, copyrights, and Intellectual Property

    Mananga, Eugene S; Reid, Alicia E; Charpentier, Thibault

    2012-02-01

    This article describes the use of an alternative expansion scheme called Floquet-Magnus expansion (FME) to study the dynamics of spin system in solid-state NMR. The main tool used to describe the effect of time-dependent interactions in NMR is the average Hamiltonian theory (AHT). However, some NMR experiments, such as sample rotation and pulse crafting, seem to be more conveniently described using the Floquet theory (FT). Here, we present the first report highlighting the basics of the Floquet-Magnus expansion (FME) scheme and hint at its application on recoupling sequences that excite more efficiently double-quantum coherences, namely BABA and C7 radiofrequency pulse sequences. The use of Λ(n)(t) functions available only in the FME scheme, allows the comparison of the efficiency of BABA and C7 sequences. Copyright © 2011 Elsevier Inc. All rights reserved.

    2009-12-01

    The papers in this special feature have been contributed by scientific partners in international research projects and from former PhD students of the Editor-in-Chief of this journal, Professor Dr Peter Hauptmann. The motivation for this feature is the occasion of Peter Hauptmann's 65th birthday on 24 July 2009 and his retirement from his chair at the Otto-von-Guericke-University, Magdeburg, Germany this autumn. Peter graduated in Physics at the Technical University Dresden and received his PhD from the Technical University Leuna-Merseburg in 1973. He habilitated in 1979. With his appointment at the Faculty of Electrical Engineering and Information Technology in 1985 the Chair of Measurement Science extended its profile to the fast growing area of sensors. Peter was one of the very early developers of ultrasonic sensor systems for process monitoring and quality assurance. The working style here was characteristic of all his future activities. He combined his background in theory and experiment on ultrasonic wave propagation and its application to material science with the advantages of rapidly developing capabilities in microelectronics and data processing. The results have meanwhile found their way into products that are now on the market worldwide. Germany's reunification opened the door to the international sensor community and the most challenging sensor research areas. Peter Hauptmann very soon became a well respected colleague and was consequently appointed as member of the Technical Program Committee of the most important sensor conferences, elected member and head of expert groups of research associations and funding organizations, and of course reviewer of many scientific journals. Nowadays Peter Hauptmann can rightly be called one of the key players in the area of sensors. Professor Hauptmann's research interests combine fundamental aspects of the sensor transduction scheme with application issues up to the use of the sensor system in the industrial world

  20. [Tone psychology and music research as catalysts of experimental-scientific practice and methodology in the circle of Carl Stumpf].

    Science.gov (United States)

    Klotz, Sebastian

    2008-09-01

    The study of acoustics, harmonics and of music has been providing scientific models since Greek Antiquity. Since the early modern ages, two separate cultures began to emerge out of the study of music: a technical acoustics and an aesthetically and philosophically inspired musical criticism. In the writings of Johann Friedrich Herbart (1811) a scientific approach to musical aesthetics and to music perception is taking shape that reinstalls the listening process as a highly complex and logical phenomenon. By opening music for a scientific psychological investigation, Herbart pioneered the physiologically and acoustically grounded seminal work by Hermann von Helmholtz On the sensations of tone (1863) which the author considered a prerequisite for musical aesthetics and music theory. Helmholtz in turn inspired the philosopher and psychologist Carl Stumpf to further investigate musical perception (beginning in 1883). To Stumpf, it provided a paradigm for experimental psychology as mental functions and phenomena could be studied in detail. These functions and phenomena are the actual objects of scientific study in Stumpf's inductive and descriptive psychology. Combining insights from statistics, ethnology, anthropology, psychoacoustics and the cultural history of mankind, Stumpf and his team developed a new blend of science which absorbs styles of reasoning, analytical procedures and academic convictions from natural history, the natural sciences and the humanities but at the same time identifies shortcomings of these approaches that fail to grasp the complexities of psychic functions. Despite their reliance on the quasi-objective phonograph and despite their commitment to objectivity, precision and measurement, mental phenomena relating to tonal perception and to music provided too complex a challenge to be easily articulated and shared by the scientific community after 1900. The essay illustrates these tensions against the background of a history of objectivity.

    The clinical professors at Gifu Pharmaceutical University (GPU) provide pharmaceutical services at GPU Pharmacy, Gifu University Hospital, and Gifu Municipal Hospital to keep their clinical skills up-to-date; they also perform clinical research in collaboration with many clinical institutes. The Laboratory of Clinical Pharmacy is part of the Department of Pharmacy Practice and Science, to which the clinical professors belong, and is composed of three clinical professors (a professor, an associate professor, and an assistant professor). The professor administers the GPU Pharmacy as its director, while the associate professor and assistant professor provide pharmaceutical services to patients at Gifu Municipal Hospital, and also provide practical training for students in the GPU Pharmacy. Collectively, they have performed research on such topics as medication education for students, clinical communication education, and analysis of clinical big data. They have also conducted research in collaboration with clinical institutes, hospitals, and pharmacies. Here, we introduce the collaborative research between the Laboratory of Clinical Pharmacy and Gifu Municipal Hospital. These studies include "Risk factors contributing to urinary protein expression resulting from bevacizumab combination chemotherapy", "Hyponatremia and hypokalemia as risk factors for falls", "Economic evaluation of adjustments of levofloxacin dosage by dispensing pharmacists for patients with renal dysfunction", and "Effect of patient education upon discharge for use of a medication notebook on purchasing over-the-counter drugs and health foods". In this symposium, we would like to demonstrate one model of the association and collaborative research between these clinical professors and clinical institutes.

    Experiences of needling techniques of Professor LI Ya- fang is introduced in this article. Gentle and superficial insertion is adopted by Professor LI in clinic. Emphases are put on the qi regulation function, needling sensation to the affected region and insertion with both hands, especially the function of the left hand as pressing hand. The gentle and superficial insertion should be done as the follows: hold the needle with the right hand, press gently along the running course of meridians with the left hand to promote qi circulation, hard pressing should be applied at acupoints to disperse the local qi and blood, insert the needle gently and quickly into the subcutaneous region with the right hand, and stop the insertion when patient has the needling sensation. While the fast needling is characterized with shallow insertion and swift manipulation: the left hand of the manipulator should press first along the running course of the meridian, and fix the local skin, hold the needle with the right hand and insert the needle quickly into the acupoint. Withdrawal of the needle should be done immediately after the reinforcing and reducing manipulations. Professor LI is accomplished in qi regulation. It is held by him that regulating qi circulation is essence of acupuncture, letting the patient get the needling sensation is the most important task of needling. Lifting, thrusting and rotation manipulations should be applied to do reinforcing or reducing. The tissue around the tip of the needle should not be too contracted or too relaxed, and the resistance should not be too strong or too weak. The feeling of the insertion hand of the practitioner should not be too smooth or too hesitant. Needle should be inserted into the skin quickly at the moment of hard pressing by the left hand. And then, slow rotation and gentle lifting and thrusting can be applied to promote the needling sensation like electric current pass through and to reach the affected region along the

    To examine the role of cholinergic neurons in the nucleus raphe magnus (NRM) in noxious heat stimulation and in the effects of morphine-induced antinociception by rats. After the cholinergic neuron selective toxin, AF64A, was microinjected into the NRM, we examined changes in the antinociceptive threshold and effects of morphine (5 mg/kg, ip) using the hot-plate (HP) and tail-flick (TF) tests. Systemic administration of morphine inhibited HP and TF responses in control rats. Microinjection of AF64A (2 nmol/site) into the NRM significantly decreased the threshold of HP response after 14 d, whereas the TF response was not affected. Morphine-induced antinociception was significantly attenuated in rats administered AF64A. Extracellular acetylcholine was attenuated after 14 d to below detectable levels in rats given AF64A. Naloxone (1 microg/site) microinjected into control rat NRM also antagonized the antinociceptive effect of systemic morphine. These findings suggest that cholinergic neuron activation in the NRM modulates the antinociceptive effect of morphine simultaneously with the opiate system.

    To explore the interrelationship among dorsal motor nucleus of the vagus (DMV), locus coeruleus (LC) and raphe magnus nucleus (NRM) in the mechanism of the descending regulation on gastric motility, which may constitute a parasympathetic local circuit, work as a neural center of gastric modulation in brainstem. Using nucleus location, electric stimulation and lesion, together with microinjection, and recording the inter-gastric pressure. (1) LC stimulation could inhibit the gastric motility significantly (P effect, while blocking the a receptor on DMV could reverse the effect. (2) NRM stimulation reduced the amplitude of gastric constriction (P effect, but blocking the 5-HT2A receptor on DMV depressed the gastric motility heavily (P effect of NRM stimulation, and microinjection of ritanserin into LC could likewise abolish it. (1) LC inhibit the gastric motility via a receptor in DMV, and meanwhile may excite it through 5-HT2A receptor in DMV, these two ways work together to keeping the gastric motility amplitude normally. (2) NRM inhibit the gastric motility via 5-HT2A receptor in LC.

  6. Effects of electroacupuncture on orphanin FQ immunoreactivity and preproorphanin FQ mRNA in nucleus of raphe magnus in the neuropathic pain rats.

    2004-07-15

    Orphanin FQ (OFQ) is an endogenous ligand for opioid receptor-like-1 (ORL1) receptor. Previous studies have shown that both OFQ immunoreactivity and preproorphanin FQ (ppOFQ) mRNA expression could be observed in the brain regions involved in pain modulation, e.g., nucleus of raphe magnus (NRM), dorsal raphe nucleus (DRN), and ventrolateral periaqueductal gray (vlPAG). It was reported that electroacupuncture (EA) has analgesic effect on neuropathic pain, and the analgesic effect was mediated by the endogenous opioid peptides. In the present study, we investigated the effects of EA on the changes of OFQ in the neuropathic pain rats. In the sciatic nerve chronic constriction injury (CCI) model, we investigated the changes of ppOFQ mRNA and OFQ immunoreactivity in NRM after EA by in situ hybridization (ISH) and immunohistochemistry methods, respectively. Then, the ppOFQ mRNA-positive and OFQ immunoreactive cells were counted under a computerized image analysis system. The results showed that expression of ppOFQ mRNA decreased and OFQ immunoreactivity increased after EA treatment in the neuropathic pain rats. These results indicated that EA modulated OFQ synthesis and OFQ peptide level in NRM of the neuropathic pain rats. Copyright 2004 Elsevier Inc.

    The present study investigated the role of calcitonin gene-related peptide (CGRP) on nociception in nucleus raphe magnus (NRM) and the interaction between CGRP and opioid peptides in NRM of rats. CGRP-like immunoreactivity was found at a concentration of 6.0+/-0. 77 pmol/g in NRM tissue of ten samples of rats, suggesting that it may contribute to physiological responses orchestrated by the NRM. The hindpaw withdrawal latency (HWL) to thermal and mechanical stimulation increased significantly after intra-NRM administration of 0.5 or 1 nmol of CGRP in rats, but not 0.25 nmol. The anti-nociceptive effect induced by CGRP was antagonized by following intra-NRM injection of 1 nmol of the CGRP receptor antagonist CGRP8-37. Furthermore, the CGRP-induced anti-nociceptive effect was attenuated by following intra-NRM administration of 6 nmol of naloxone. The results indicate that CGRP and its receptors play an important role in anti-nociception, and there is a possible interaction between CGRP and opioid peptides in NRM of rats.

    Several lines of investigation show that the rostral ventromedial medulla is a critical relay for midbrain regions, including the nucleus cuneiformis (CnF), which control nociception at the spinal cord. There is some evidence that local stimulation or morphine administration into the CnF produces the effective analgesia through the nucleus raphe magnus (NRM). The present study tries to determine the effect of morphine-induced analgesia following microinjection into the CnF in the absence of NRM. Seven days after the cannulae implantation, morphine was microinjected bilaterally into the CnF at the doses of 0.25, 1, 2.5, 5, 7.5 and 10 microg/0.3 microl saline per side. The morphine-induced antinociceptive effect measured by tail-flick test at 30, 60, 90 and 120 min after microinjection. The results showed that bilateral microinjection of morphine into the CnF dose-dependently causes increase in tail-flick latency (TFL). The 50% effective dose of morphine was determined and microinjected into the CnF (2.5 microg/0.3 microl saline per side) in rats after NRM electrolytic lesion (1 mA, 30 s). Lesion of the NRM significantly decreased TFLs, 30 (Peffects through the opioid receptors in the CnF. It is also appeared that morphine-induced antinociception decreases following the NRM lesion but it seems that there are some other descending pain modulatory pathways that activate in the absence of NRM.

    The nucleus raphe magnus (NRM) is involved in thermoregulatory processing. There is a correlation between changes in the firing rates of the cells in the NRM and the application of the peripheral thermal stimulus. we examined the effect of reversible inactivation and excitation of NRM on mechanisms involved in tail blood flow (TBF) regulation in hypothermia. Hypothermia was induced in Male Wistar rats and cannula was implanted above the NRM. To evaluate the effect of nucleus inactivation on TBF, the amount of TBF was measured by Laser Doppler in hypothermic rats, before and after lidocaine microinjection into NRM. TBF was also measured after glutamate microinjection to assess the effect of nucleus excitation in hypothermic rats. Results indicated that after dropping TBF by hypothermia, microinjection of lidocaine into NRM significantly decreased TBF from 54.43 +- 5.7 to 46.81 +- 3.4, whereas glutamate microinjection caused a significant increase from 44.194 +- 0.6 to 98 +- 10.0 CONCLUSION: These data suggest that NRM have thermoregulatory effect in response to hypothermia.

    We study the tuning of the Geneva Monte Carlo framework to LHC data. Geneva improves the predictions for Drell-Yan production by including NNLO QCD corrections and extending the resummation accuracy to NNLL$'$ for 0-jettiness and NLL for 1-jettiness. The partonic results provided by Geneva are interfaced to Pythia 8 for showering including its multiple parton interaction (MPI) model. This allows us to obtain sensible predictions for Underlying Event (UE) sensitive observables too. Retuning Geneva + Pythia 8 to LHC data with the Professor 2 package shows an improved agreement for both UE sensitive and more inclusive observables.

    The first woman to earn a Professorship at a University in Europe was Laura Maria Caterina Bassi, who earned a professorship in physics at the University of Bologna in 1732. Almost 300 years and three waves of feminism later, in 2016, women typically still only comprise 20% (or less) of the number of full professors in Europe. This opinion article will discuss the experiences of being a female academic today and the factors contributing to the academic gender gap from the perspective of a "young" natural scientist, as well as providing constructive suggestions for strategies to empower women in the academic world.

    This paper adds to discussion of transactional sex relationships in Africa by examining the distinction between transactional sex and sexual harassment in the context of professor-student relationships and their inherent power dynamics. By exploring the ways in which female university students in urban Benin toe the line between empowered agent and victim, I show how the power differential between professor and student obstructs the professor's ability to objectively determine consent, and examine why, in spite of this differential, male professors are frequently perceived as the victims of these relationships. Ethnographic data were gathered through participant observation on a public university campus in Benin and in-depth interviews and focus groups with 34 students and 5 professors from that university. Findings suggest that the problem of sexual harassment on campus will be difficult to address so long as transactional sex relationships between professors and students are permitted to continue.

    Professor CHEN Xiuhua 's clinical experiences were introduced in the intervention on atopic dermatitis with external therapies of TCM acupuncture. On the basis of the theory as cultivating the earth and clearing the heart from professor CHEN Dacan and in terms of the disease stages and skin lesion characteristics, as well as in consideration of syndrome differen-tiation, the acupoints for strengthening the spleen and clearing heart fire are selected, such as Zhongwan (CV 12), Daheng (SP 15), Shuifen (CV 9), Tianshu (ST 25), Neiguan (PC 6) and Quchi (LI 11). For the repair of skin lesion, the integration of Chinese and western medicine is used, with the internal application and external use of Chinese herbal medicines involved. The topical ointments are selected rationally. The self-blood therapy is used with acupuncture, bleeding therapy and acupoint injection applied in combination on the basis of the theory of TCM zangfu organs and modern immunological mechanism, which stimulates the nonspecific immune response in the body and strengthens acupoint stimulus effects. Medical thread therapy of Guangxi Zhuang medicine is used in moxibustion for skin damage, which effectively stops itching and promotes wound healing and skin repair.

    Full Text Available The presence of the Burnout syndrome in professors may be regarded as a deterioration of their mental health with negative impacts on their job performance. It is known that teachers develop different activities in the areas of teaching, outreach and research. This study aims to analyze the relationship between the Burnout syndrome and self-efficacy beliefs and the academic performance in professors of the psychology and dentistry programs at a private university in the city of Barranquilla. This study is empirical and analytical with a descriptive-correlational design. The study population consisted of 93 teachers of the psychology and dentistry programs. To choose the sample, a non-probabilistic sample was used according to the inclusion and exclusion criteria that allowed selecting a total of 36 teachers who met the criteria for the study. The instruments that were used in this study was the Maslach Burnout Inventory (MBI, 1981 adapted by Seisdedos (1997, and the Teachers’ Self-Efficacy Beliefs of Tschannen-Moran and Woolfolk (2001 adapted by Covarrubias and Mendoza (2016. According to the results, it was observed that there is no significant relationship between Burnout, Self-efficacy Belief and the academic performance.
