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.

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.

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

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

On the inverse Magnus effect in free molecular flow

Science.gov (United States)

Weidman, Patrick D.; Herczynski, Andrzej

2004-02-01

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.

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

Negative Magnus lift on a rotating sphere at around the critical Reynolds number

Science.gov (United States)

Muto, Masaya; Tsubokura, Makoto; Oshima, Nobuyuki

2012-01-01

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.

Comparison among Magnus/Floquet/Fer expansion schemes in solid-state NMR

2015-04-01

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.

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.

Anisotropic Magnus Force in Type-II Superconductors with Planar Defects

Science.gov (United States)

Monroy, Ricardo Vega; Gomez, Eliceo Cortés

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.

Magnus force and inertia properties of magnetic vortices in weak ferromagnets

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.

Negative Magnus Effect on a Rotating Sphere at around the Critical Reynolds Number

2011-01-01

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.

A review of the Magnus effect in aeronautics

Seifert, Jost

2012-11-01

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.

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.

Magnus force in superfluids and superconductors

International Nuclear Information System (INIS)

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

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.

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.)

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.

Sturek, W. B.; Schiff, L. B.

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.

Magnus approximation in the adiabatic picture

Klarsfeld, S.; Oteo, J.A.

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

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.

2018-05-01

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.

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

Science.gov (United States)

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.

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.

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

Science.gov (United States)

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.

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.

Los tres experimentos dieron resultados positivos. Sin embargo, el análisis de materia orgánica en el suelo marciano demostró la ausencia total de carbono orgánico. Este hallazgo fue utilizado como uno de los argumentos más sólidos en contra de la existencia de vida en la superficie del planeta Marte. Como preparación para futuras misiones a Marte en búsqueda de vida es necesario probar los instrumentos en localidades terrestres que pudieran ser ambientes análogos a Marte.

Estudios químicos y microbiológicos del suelo de Atacama sugieren que el corazón del desierto es en realidad un buen análogo de Marte, ya que no posee vida macroscópica y microscópica, tiene niveles muy bajos de materia orgánica, y sus suelos son muy reactivos. En colaboración con científicos franceses y estadounidenses, estamos preparando una misión robótica dirigida por la NASA para la búsqueda de vida pasada o presente en Marte por lo que el Desierto de Atacama en Chile es el escenario para la preparación de esta misión espacial.

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.

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.

Development of an experimental setup for analyzing the influence of Magnus effect on the performance of airfoil

Science.gov (United States)

Aktharuzzaman, Md; Sarker, Md. Samad; Safa, Wasiul; Sharah, Nahreen; Salam, Md. Abdus

2017-12-01

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.

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

Neurocinematography in Pre-World War II Netherlands: The Magnus-Rademaker Collection.

Koehler, Peter J; Lameris, Bregt; Hielscher, Eva

2016-01-01

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.

The Magnus problem in Rodrigues-Hamilton parameters

Koshliakov, V. N.

1984-04-01

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.

Amarante, J.C.A.

1989-01-01

The laminar flow around a rotating cylinder is studied, through the numerical solution of the full Navier-Stokes equations, for Reynolds number, based on cylinder radius, varying between 0.5 and 25 and for non-dimensional tangential velocities of the body surface between zero and 8. The Taylor and Hughes method is employed in the theoretical investigation. The Magnus lift coefficient and the drag coefficient are obtained and the presure and vorticity distribution are calculated.

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.

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 purpose of this paper is to critically review some of the main theoretical tenets in Ezequiel Martínez Estrada’s pessimistic stance about the Argentinean history and society of his time. Focusing on his critical remarks about the so-called «literatura o poesía gauchesca» as well as on his enthusiastic assessment of José Hernández’ Martín Fierro, the achievements and missing points in Martínez Estrada’s skeptical diagnosis will be underlined and put in broader philosophical context. For the Argentinean writer the controversial notion of a “superimposed reality” – as he infers its existence from the Martín Fierro – captures a kind of ambivalent metaphysical concurrence among the literary creation, the geographical setting and the sociopolitical state of the country.

A mini-invasive adductor magnus tendon transfer technique for medial patellofemoral ligament reconstruction: a technical note.

Science.gov (United States)

Sillanpää, Petri J; Mäenpää, Heikki M; Mattila, Ville M; Visuri, Tuomo; Pihlajamäki, Harri

2009-05-01

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.

Black-Right-Pointing-Pointer We describe all the work done for the integration. - Abstract: Keeping in mind the necessities of a modern control system for fusion devices, such as modularity and a distributed architecture, an upgrade of the present FTU feedback control system was planned, envisaging also a possible reutilization in the proposed FAST experiment [1]. For standardization and efficiency purposes we decided to adopt a pre-existent ITER-relevant framework called MARTe [2], already used with success in other European Tokamak devices [3]. Following the developments shown in [4], in this paper we report on the structure of the new feedback system, and how it was integrated in the current control structure and pulse programming interface, and in the other MARTe systems already in FTU: RT-ODIN [5] and the ECRH and LH [6] satellite stations. The new feedback system has been installed in the FTU backup station (known as 'Feedback B'), which shares the input signals with the actual feedback system, in order to simplify the validation and debug of the new controller by testing it in parallel with the current one. Experimental results are then presented.

Study on Physical Mechanism of the Magnus Effect

Science.gov (United States)

Maruyama, Yuichi

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.

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.

3-D magnetic field calculations for wiggglers using MAGNUS-3D

International Nuclear Information System (INIS)

Pissanetzky, S.; Tompkins, P.

1988-01-01

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

Within the fusion community two modern framework-based software architectures have emerged as powerful tools for developing algorithms for real-time control of complex systems while maintaining the flexibility required when operating a physics experiment. The two frameworks are known as DCS (Discharge Control System), from ASDEX Upgrade and MARTe (Multithreaded Application Real-Time executor), originally from JET.

DCS and MARTe operate in parallel with synchronised state machines and a common message logger. Configuration data is exchanged before the real-time phase. During the real-time phase, structured data is exchanged via shared memory and an existing DCS algorithm is replicated within MARTe. The coupling tests the flexibility and identifies the respective strengths of the two frameworks, providing a well-informed basis on which to move forward and design a new ITER real-time framework.

Size sexual dimorphism was investigated on 695 skulls of four Mustelidae species. By extent of increasing of differences between sexes the species are placed in following order: European pine marten (Martes martes), European mink (Mustela lutreola), American mink (Neovison vison), and European polecat (Mustela putorius). Extent of the dimorphism characterizes ecological plasticity of the species and is population characteristic. It is shown that M. martes takes specific and relatively narrow ecological niche of forest ecosystems, entering into weak competitive relationships with smaller Mustelidae species. The level of sexual dimorphism of M. lutreola, N. vison and M. putorius reflects intensity of its interspecific relationships within study area. High level of sexual dimorphism of M. putorius is determined by further divergence of ecological niches of males and females, and also appears to be compensatory mechanism reducing consequences of hardened environmental requirements.

Variabilità microsatellitare in popolazioni italiane di martora, Martes martes

Directory of Open Access Journals (Sweden)

Licia Colli

2003-10-01

Full Text Available La martora, Martes martes, è un mustelide storicamente presente su gran parte del territorio italiano, soprattutto dove siano presenti foreste mature altamente strutturate e ricche di risorse. Nel corso dei decenni passati, cause quali la deforestazione con conseguente frammentazione dell'habitat, la caccia e la persecuzione da parte dell'uomo hanno portato ad un sensibile declino sia nel numero d'individui sia di popolazioni in tutta l'Europa. Frammentazione degli areali e diminuzione del numero di soggetti costituiscono le cause principali di un limitato flusso genico con conseguente formazione di popolazioni isolate di martora e perdita di variabilità genetica (Kyle et al., 2003. Per queste ragioni la martora risulta attualmente tutelata secondo quanto previsto dalla Convenzione di Berna (appendice III e dalla Direttiva europea 92/43/CEE "Habitats & Species". Di fronte a prospettive di tipo conservazionistico, diventa necessario disporre di metodologie per la valutazione della variabilità residua nella specie a livello d'individui e di popolazioni. Secondo numerosi Autori, i microsatelliti costituiscono marcatori molto efficaci nella descrizione della struttura genetica e della storia demografica di specie (Beaumont & Bruford, 1999; Linares, 1999.

From Sarmiento to Martí and Hostos: Extricating the Nation from Coloniality

Full Text Available The present article examines constructions of  race, nation and mestizaje in work of Domingo  Faustino Sarmiento, José Martí and Eugenio  Maria de Hostos. The first championed the prevailing nineteenth-century view that humanity  was being debilitated by a constant battle between  civilization and barbarism while the two Antilleans questioned it in their search for a society  liberated from coloniality. Martí denied the notion  of privilege based on Europeanness, proclaiming  that whites, blacks, indigenous and mixed-race  peoples could all claim equal rights under natural  law. Hostos agreed with Martí but took his recommendation one step further by proposing race  mixing, with all ethnic groups equally forming a  new society. Therefore Martí’s negation of racial  differences becomes with Hostos a quest for a  society that would eventually become homogeneous through miscegenation. The study concludes  that there is a timelessness inherent to Martí and  Hostos’s work that still speaks to us today in the  midst of a new awareness of ethnicity’s impact on  society. Resumen:De Sarmiento a Martí y Hostos: Rescatando al país de la colonialidadEl presente artículo examina las construcciones de  raza, nación y mestizaje en las obras de Domingo  Faustino Sarmiento, José Martí y Eugenio María de  Hostos.

José Martí y la ciencia

José Suárez Lezcano

2015-11-01

Full Text Available Nuestro José Martí, ejemplo de una formación humanística integral, escribió en una carta a María Mantilla:”Donde yo encuentro poesía mayor es en los libros de ciencia…” Martí vio la ciencia como un fenómeno social y consideró que el desarrollo científico técnico debía estar en función de la satisfacción de las necesidades de las grandes mayorías. Su sistemática voluntad  de cultivarse, de tratar de entender al mundo y no sólo de vivirlo, de razonarlo, fue el motor principal que llevaría a Martí a hacerse de una cultura científica y técnica poco común entre los hombres de su época. También el hecho de vivir durante muchos años en los Estados Unidos le permitió analizar con  profundidad y realismo la sociedad de la época, y por tanto llegó a tener una visión muy avanzada de la relación hombre – naturaleza - sociedad, llegando a convertirse en un gran divulgador de los avances de la ciencia y la técnica de aquella época. La originalidad del periodismo de nuevo tipo que inicia José Martí como vehículo para la divulgación científico - técnica encuentra una de sus más altas expresiones en la revista “La América”. Esta publicación había comenzado en abril de 1882, en Nueva York, bajo la dirección de Rafael de Castro Palomino, quien solicita la colaboración del poeta. A partir del mes de marzo de 1883, el Maestro redacta “La América” en su totalidad, desde los titulares hasta los artículos ensayísticos. Martí caracteriza “La América” como “periódico útil”, pues se dedicó a divulgar los adelantos de la industria, comercio y agricultura de los productores de la América del Norte, y en el avisador prudente de los compradores de la América del Sur. Este carácter de la publicación permite a José Martí tratar desde las páginas de “La América” los recientes descubrimientos científicos, la reseña detallada de las exposiciones que exhibían los últimos logros de la t

La historia orbital de Deimos y la oblicuidad de Marte

Science.gov (United States)

Brunini, A.; Yokoyama, T.

Recientemente, se ha demostrado mediante extensas integraciones numéricas, que la rotación de Marte pasó repetidamente por estados caóticos de movimiento, debido al pasaje por zonas de resonancia spin - órbita. En dichas circunstancias, la oblicuidad marciana pudo haber sufrido grandes excursiones de varias decenas de grados. Las consecuencias de dichas variaciones son de extrema importancia en el contexto de la búsqueda de manifestaciones de vida fósil en dicho planeta. El estudio de la dinámica orbital del satélite más exterior de Marte, Deimos, nos ha permitido comprobar, en el marco de las distintas teorías sobre su orígen, que la oblicuidad de Marte dificilmente pudo haber sufrido variaciones que la aparten más de 10o respecto de actual valor. Este resultado parece ser mucho más robusto que las simulaciones numéricas de Touma y Wisdom asi como las de Laskar y Robutel, lo que permite poner cotas más severas a la evolución paleoclimática de Marte.

Vooruitgang en ondergang: historiese dialektiek in twee tekste van Hans Magnus Enzensberger

Directory of Open Access Journals (Sweden)

J.P.C. van den Berg

2006-07-01

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.

Nucleus Raphe Magnus (NRM) that is involved in the regulation of body temperature contains nitric oxide (NO) synthase. Considering the effect of NO on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. To this end, tail blood flow of male Wistar rats was measured by laser doppler following the induction of hypothermia. Intra-NRM injection of SNP (exogenous NO donor, 0.1- 0.2 μl, 0.2 nM) increased the blood flow. Similarly, unilateral microinjection of glutamate (0.1- 0.2 μl, 2.3 nM) into the nucleus increased the blood flow. This effect of L-glutamate was reduced by prior intra NRM administration of NO synthase inhibitor N(G)-methyl-L-arginine or N(G)-nitro-L-arginine methyl ester (L-NAME, 0.1 µl, 100 nM). It is concluded that NO modulates the thermoregulatory response of NRM to hypothermia and may interact with excitatory amino acids in central skin blood flow regulation.

Validation by means of simulation is a crucial step when developing real-time control systems. Modeling and simulation are an essential tool since the early design phase, when the control algorithms are designed and tested. This phase is commonly carried out in off-line environments such as Matlab and Simulink. A MARTe-based simulator has been recently developed to validate the new JET Vertical Stabilization (VS) system. MARTe is the multi-thread framework used at JET to deploy hard real-time control systems. This paper presents the software architecture of the MARTe-based simulator and it shows how this tool has been effectively used to evaluate the effects of Edge Localized Modes (ELMs) on the VS system. By using the simulator it is possible to analyze different plasma configurations, extrapolating the limit of the new vertical amplifier in terms of the energy of the largest rejectable ELM.

Operating cycle optimization for a Magnus effect-based airborne wind energy system

International Nuclear Information System (INIS)

Milutinović, Milan; Čorić, Mirko; Deur, Joško

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

Martí resume una visión inicial de nuestra América en la figura lítica de Chacmool cuando después de ser expropiada por el gobierno yucateco, el Apóstol cubano la admira en la ciudad de Mérida y expresa que es la síntesis de las culturas americanas. Aspecto poco estudiado en la obra de Martí es este acercamiento etnográfico a la realidad maya de Yucatán y Guatemala.   This paper aims at presenting and examining the change of perception José Martí underwent in relation to the role of the native peoples of America between 1875 and 1878, the years he lived in Mexico and Guatemala, during which he spent a large amount of time in Yucatan, where he was able to get to know the Mayan culture and its people first hand. Martí summarized his initial vision of our America in the lithic figure of Chacmool, which he was able to admire in the city of Merida, after it had been expropriated by the government of Yucatan. The Cuban apostle described this as a synthesis of American cultures. This ethnographic insight into the Mayan reality in Yucatan and Guatemala represents a scarcely explored aspect of Martí's work.

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

Full Text Available Semblanza del escritor y político cubano José Martí (1853-1895, con especial atención a la vigencia de su pensamiento ético, base de su permanente actualidad. Martí fue el organizador y líder de la última guerra americana contra el colonialismo europeo clásico, pero el sentido profundo que dio a esa lucha la convirtió en una verdadera guerra de liberación nacional: el primer movimiento concreto contra el imperialismo. Entre los rasgos más originales del pensamiento martiano están: la proclamación de la igualdad de razas; la búsqueda de la superación de las diferencias de clase mediante el equilibrio de las fuerzas sociales; la reivindicación de la solidaridad hacia los humildes como un deber; la predicación de una “guerra sin odios”, que debía ser obra del pueblo y no de líderes; la comprensión y definición de Nuestra América; la insistencia en la necesidad de una descolonización cultural latinoamericana; y el antiimperialismo.   This paper is a sketch of the Cuban writer and politician José Martí (1853-1895, with special attention to the validity of his ethical thinking, which is the basis of his permanent relevance. Martí was the organizer and leader of the last American war against European colonialism, but the deep commitment he made to that struggle turned it into a war of national liberation, the first concrete movement against imperialism. Among the most original features of Martí’s thought are the proclamation of the equality of races; the search for overcoming class differences through the balance of social forces; solidarity with the poor being considered a duty; the preaching of a “war without hates” that must be the work of the people, its leaders; the comprehension and definition of Our America; the insistence on the need, throughout Latin America, of cultural decolonization; and an anti-imperialistic stance.

Translational research typically requires data abstracted from medical records as well as data collected specifically for research. Unfortunately, many data within electronic health records are represented as text that is not amenable to aggregation for analyses. We present a scalable open source SQL Server Integration Services package, called Regextractor, for including regular expression parsers into a classic extract, transform, and load workflow. We have used Regextractor to abstract discrete data from textual reports from a number of 'machine generated' sources. To validate this package, we created a pulmonary function test data mart and analyzed the quality of the data mart versus manual chart review. Eleven variables from pulmonary function tests performed closest to the initial clinical evaluation date were studied for 100 randomly selected subjects with scleroderma. One research assistant manually reviewed, abstracted, and entered relevant data into a database. Correlation with data obtained from the automated pulmonary function test data mart within the Northwestern Medical Enterprise Data Warehouse was determined. There was a near perfect (99.5%) agreement between results generated from the Regextractor package and those obtained via manual chart abstraction. The pulmonary function test data mart has been used subsequently to monitor disease progression of patients in the Northwestern Scleroderma Registry. In addition to the pulmonary function test example presented in this manuscript, the Regextractor package has been used to create cardiac catheterization and echocardiography data marts. The Regextractor package was released as open source software in October 2009 and has been downloaded 552 times as of 6/1/2012. Collaboration between clinical researchers and biomedical informatics experts enabled the development and validation of a tool (Regextractor) to parse, abstract and assemble structured data from text data contained in the electronic health

Development of real-time applications is usually associated with nonportable code targeted at specific real-time operating systems. The boundary between hardware drivers, system services, and user code is commonly not well defined, making the development in the target host significantly difficult. The Multithreaded Application Real-Time executor (MARTe) is a framework built over a multiplatform library that allows the execution of the same code in different operating systems. The framework provides the high-level interfaces with hardware, external configuration programs, and user interfaces, assuring at the same time hard real-time performances. End-users of the framework are required to define and implement algorithms inside a well-defined block of software, named Generic Application Module (GAM), that is executed by the real-time scheduler. Each GAM is reconfigurable with a set of predefined configuration meta-parameters and interchanges information using a set of data pipes that are provided as inputs and required as output. Using these connections, different GAMs can be chained either in series or parallel. GAMs can be developed and debugged in a non-real-time system and, only once the robustness of the code and correctness of the algorithm are verified, deployed to the real-time system. The software also supplies a large set of utilities that greatly ease the interaction and debugging of a running system. Among the most useful are a highly efficient real-time logger, HTTP introspection of real-time objects, and HTTP remote configuration. MARTe is currently being used to successfully drive the plasma vertical stabilization controller on the largest magnetic confinement fusion device in the world, with a control loop cycle of 50 ?s and a jitter under 1 ?s. In this particular project, MARTe is used with the Real-Time Application Interface (RTAI)/Linux operating system exploiting the new ?86 multicore processors technology.

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.

Full Text Available A. crassiflora Mart. a Brazilian savannah fruit, is a source of phytochemical compounds that possess a wide array of biological activities, including free radical scavenging. This native fruit proved to potentialize the mutagenic process in previous in vivo investigations. The aim of the present study was to investigate the effects of A. crassiflora Mart. pulp intake on colonic cell proliferation and on the development of Aberrant Crypt Foci (ACF in male Wistar rats. The animals were fed with either a commercial diet or a diet supplemented with A. crassiflora Mart. pulp mixed in 1%, 10% or 20% (w/w for 4 weeks or 20 weeks. The carcinogen 1,2-dimethylhydrazine dihydrochloride (4 doses, 40 mg kg-1 each was used to induce colonic ACF. After euthanasia, the blood, liver and colon samples were collected for biochemical determinations, oxidative stress or ACF development analysis, respectively. Immunohistochemical analyses of the colonic mucosa were performed using antibodies against proliferating cell nuclear antigen (PCNA in normal-appearing colonic crypt and β-catenin in ACF. There was no ACF development in the colon from groups treated with A. crassiflora Mart. pulp. Also, the biochemical and oxidative stress analysis, PCNA labeling and ACF development (number, multiplicity or cellular localization of β-catenin were unchanged as a result of marolo pulp intake. Thus, the present results suggest that A. crassiflora Mart. pulp intake did not exert any protective effect in the colon carcinogenesis induced by DMH in rats.

Propagators for the Time-Dependent Kohn-Sham Equations: Multistep, Runge-Kutta, Exponential Runge-Kutta, and Commutator Free Magnus Methods.

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.

The mycological legacy of Elias Magnus Fries.

Petersen, Ronald H; Knudsen, Henning

2015-06-01

The taxonomic concepts which originated with or were accepted by Elias Magnus Fries were presented during his lifetime in the printed word, illustrative depiction, and in collections of dried specimens. This body of work was welcomed by the mycological and botanical communities of his time: students and associates aided Fries and after his passing carried forward his taxonomic ideas. 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.

The diagnosis of melanoma metastatic to lymph node remains a difficult problem given its histological diversity. We examined the staining patterns of S-100, NK1/C3, HMB-45, and MART-1 (DC10) in melanoma metastases to lymph nodes. Immunohistochemical stains were performed on tissue sections of 126 formalin-fixed lymph nodes from 126 patients with an established diagnosis of metastatic melanoma. A total of 98% of cases (123 of 126) stained positive for S-100, 93% (117 of 125) stained positive for NK1/C3, 82% (103 of 126) stained positive for MART-1, and 76% (95 of 125) stained positive for HMB-45. The distribution and intensity of staining varied among these markers. A diffuse staining pattern, defined as >50% of tumor cells stained, was observed in 83% of MART-1-positive cases but in only 56% of S-100-positive cases, 48% of NK1/C3-positive cases, and 34% of HMB-45-positive cases. A maximally intense signal was almost always observed for MART-1 (83% of positive cases) but was rarely observed for NK1/C3 (20%). S-100 and HMB-45 showed maximally intense staining in 50% and 54% of cases, respectively. S-100 and NK1/C3 stained both histiocytes and melanocytes, whereas MART-1 and HMB-45 stained only melanocytes. Seventy-eight cases (63%) stained positive for all 4 markers, 17 cases (14%) stained for all markers except HMB-45, 13 cases (10%) stained for all markers except MART-1, 6 cases (5%) stained only with S-100 and NK1/C3, 4 cases (3%) stained only with S-100 and HMB-45, and 2 cases stained for all markers except S-100. One case each stained for the following: only S-100, only S-100 and HMB-45, and all markers except NK1/C3. One case exhibited absence of staining for any of these markers. We demonstrate that lymph node metastases of melanoma are heterogeneous with regard to tumor marker expression. S-100 and NK1/C3 were the most sensitive stains for detecting metastatic melanoma; however, they both also stain other nontumor cells in lymph nodes. MART-1 did not stain

2016-11-01

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.

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

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.

Full Text Available Este artigo apresenta uma leitura de José Martí como fonte histórica da educação popular na América Latina. Parte-se do pressuposto de que não pode haver uma verdadeira refundamentação sem o retorno àquilo que sejam momentos, idéias ou princípios fundantes da educação popular. Após situar brevemente o pensamento e a obra de José Martí, caracteriza-se o conceito de educação popular como educação do povo, no sentido de educação universal. Num outro nível, busca-se identificar na obra de Martí traços da educação popular como um movimento político-pedagógico que se configura especialmente a partir da segunda metade do século passado. A premissa é que, num dado momento, educação do povo e educação popular deixam de ser termos equivalentes e que, em José Martí, temos elementos para pensar esses dois termos de forma dialética, num movimento de recriação de uma prática que, embora cindida pelas contingências históricas, é única. São identificados em sua obra quatro princípios da educação popular: a valorização da pluralidade de saberes; a relação interpessoal como ambiente para o aprender-ensinar e base para a transformação social; o conhecimento da realidade a partir de uma perspectiva emancipatória como ato político; e a educação como processo autoformativo da sociedade.This article presents José Martí as a historical source of popular education in Latin America. It starts from the assumption that there can be no true re-foundation without the return to those founding moments, ideas or principles of popular education. After giving a brief account of Martí's work and thought, we characterize the concept of popular education as education of the people, in the sense of a universal education. On a different level, we seek to identify in Martí's work elements of popular education as a political-pedagogical movement that takes shape especially since the latter half of the 20th century. The

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

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.

Etnocentrismo, racismo y miedo: los indígenas y los incultos en Martí

Directory of Open Access Journals (Sweden)

Jorge Camacho

2010-04-01

Full Text Available In the following article I return to the idea of ethnicity and liberalism in Latin America during the last part of the 19th century. I also discuss Martí’s view of the Indians after 1885, when his chronicles were fueled by the rhetoric of pro-indigenous groups such as the Friends of Indians Association. I propose to look at other ways in which Martí’s ethnocentric view of culture and race intertwined with his agenda of “defending” the Indians, especially in his essay “Nuestra América.” For that purpose I retrace some of my previous arguments and discuss other essays that have recently elaborated on Martí’s “other side”, the one that imposes on the Indians his own liberal agenda, and the vision of modernity that the elites were constructing in Latin America at the end of 19th century. In my previous articles I discussed Martí’s chronicles on the Guatemalan, Mexican and American Indians and here I will focus on the similarities between the positivists in Mexico and Martí’s emphasis on “scientific politics” as well as his fear that those that were at the lowest level of society could one day revolt against the republic and destroy the justice “accumulated in books.” For books symbolized for Martí the “lettered elite”, those that had power and exercised it to their own advantage. He talked about this fear in Mexico, and in his most famous essay he returned to it again with a somewhat different perspective, but still with the conviction that within a democracy everything could be solved and a revolt from the “unlettered” masses was not justified. I argue that even if “Nuestra América” meant a more positive view of the “Indian problem”, Martí still considers the Indians, the “gauchos” and the rest of the “incultos” as a threat. They were the natural ally of the “caudillos” that ruled for so long Latin America, charismatic caudillos such as Juan Manuel de Rosas.

Ionizing radiation affects generation of MART-1-specific cytotoxic T cell responses by dendritic cells

Full text: The human MART-1/Melan-A (MART-1) melanoma tumor antigen is known to be recognized by cytotoxic T lymphocytes (CTLs) and several groups are using this target for clinical immunotherapy. Most approaches use dendritic cells (DCs) that are potent antigen presentation cells for initiating CTL responses. In order for CTL recognition to occur, DCs must display 9-residue antigenic peptides on MHC class I molecules. These peptides are generated by proteasome degradation and then transported through the endoplasmic reticulum to the cell surface where they stabilize MHC class I expression. Our previous data showed that irradiation inhibits proteasome function and, therefore, we hypothesized that irradiation may inhibit antigen processing and CTL activation, as has been shown for proteasome inhibitors. To study the importance of irradiation effects on DCs, we studied the generation MART-1-specific CTL responses. Preliminary data showed that irradiation of murine bone marrow derived DCs did not affect expression of MHC class I, II, CD80, or CD86, as assessed by flow cytometric analyses 24-hour after irradiation. The effect of irradiation on MART-1 antigen processing by DCs was evaluated using DC transduced with adenovirus MART-1 (AdVMART1). C57BL/6 mice were immunized with AdVMART1 transduced DCs, with and without prior irradiation. IFN-γ production was measured by ELISPOT assays after 10-14 days of immunization. Prior radiation treatment resulted in a significant decrease in MART-1-specific T cell responses. The ability of irradiated and non-irradiated AdVMART1/DC vaccines to protect mice against growth of murine B16 tumors, which endogenously express murine MART-1, was also examined. AdVMART1/DC vaccination protected C57BL/6 mice against challenge with viable B16 melanoma cells while DCs irradiated (10 Gy) prior to AdVMART1 transduction abrogated protection. These results suggest that proteasome inhibition in DCs by irradiation may be a possible pathway in

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.

Among the relatively large number of known tumor-associated antigens (TAA) which are recognized by human CD8 T-cells, Melan-A/MART-1 is one of the most-if not the most-frequently used target for anti-cancer vaccines in HLA-A2 + melanoma patients. In this study, we analyzed the killing of a large...... panel of melanoma cells by a high avidity, MART-1-specific T-cell clone or a MART-1-specific, polyclonal T-cell culture. Strikingly, we observed that the MART-1-specific T-cells only killed around half of the analyzed melanoma cell lines. In contrast a Bcl-2-specific T-cell clone killed all melanoma...... cell lines, although the T-cell avidity of this clone was significantly lower. The MART-1-specific T-cell clone expressed NKG-2D and was fully capable of releasing both perforin and Granzyme B. Notably, the resistance to killing by the MART-1-specific T-cells could be overcome by pulsing...

Background: The characterization of the genes encoding melanoma-associated antigens MART-1 or gp100, recognized by T cells, has opened new possibilities for the development of immunization strategies for patients with metastatic melanoma. With the use of recombinant adenoviruses expressing either MART-1 or gp100 to immunize patients with metastatic melanoma, we evaluated the safety, immunologic, and potential therapeutic aspects of these immunizations. Methods: In phase I studies, 54 patients received escalating doses (between 107 and 1011 plaque-forming units) of recombinant adenovirus encoding either MART-1 or gp100 melanoma antigen administered either alone or followed by the administration of interleukin 2 (IL-2). The immunologic impact of these immunizations on the development of cellular and antibody reactivity was assayed. Results: Recombinant adenoviruses expressing MART-1 or gp100 were safely administered. One of 16 patients with metastatic melanoma receiving the recombinant adenovirus MART-1 alone experienced a complete response. Other patients achieved objective responses, but they had received IL-2 along with an adenovirus, and their responses could be attributed to the cytokine. Immunologic assays showed no consistent immunization to the MART-1 or gp100 transgenes expressed by the recombinant adenoviruses. High levels of neutralizing antibody were found in the pretreatment sera of the patients. Conclusions: High doses of recombinant adenoviruses could be safely administered to cancer patients. High levels of neutralizing antibody present in patients' sera prior to treatment may have impaired the ability of these viruses to immunize patients against melanoma antigens. PMID:9862627

Drift of suspended ferromagnetic particles due to the Magnus effect

Science.gov (United States)

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.

Numerical Simulations to Assess ART and MART Performance for Ionospheric Tomography of Chapman Profiles.

Science.gov (United States)

Prol, Fabricio S; Camargo, Paulo O; Muella, Marcio T A H

2017-01-01

The incomplete geometrical coverage of the Global Navigation Satellite System (GNSS) makes the ionospheric tomographic system an ill-conditioned problem for ionospheric imaging. In order to detect the principal limitations of the ill-conditioned tomographic solutions, numerical simulations of the ionosphere are under constant investigation. In this paper, we show an investigation of the accuracy of Algebraic Reconstruction Technique (ART) and Multiplicative ART (MART) for performing tomographic reconstruction of Chapman profiles using a simulated optimum scenario of GNSS signals tracked by ground-based receivers. Chapman functions were used to represent the ionospheric morphology and a set of analyses was conducted to assess ART and MART performance for estimating the Total Electron Content (TEC) and parameters that describes the Chapman function. The results showed that MART performed better in the reconstruction of the electron density peak and ART gave a better representation for estimating TEC and the shape of the ionosphere. Since we used an optimum scenario of the GNSS signals, the analyses indicate the intrinsic problems that may occur with ART and MART to recover valuable information for many applications of Telecommunication, Spatial Geodesy and Space Weather.

The Multi-threaded Application Real-Time executor (MARTe) is a C++ framework that provides a development environment for the design and deployment of real-time applications, e.g. control systems. The kernel of MARTe comprises a set of data-driven independent blocks, connected using a shared bus. This modular design enforces a clear boundary between algorithms, hardware interaction and system configuration. The architecture, being multi-platform, facilitates the test and commissioning of new systems, enabling the execution of plant models in offline environments and with the hardware-in-the-loop, whilst also providing a set of non-intrusive introspection and logging facilities. Furthermore, applications can be developed in non real-time environments and deployed in a real-time operating system, using exactly the same code and configuration data. The framework is already being used in several fusion experiments, with control cycles ranging from 50 microseconds to 10 milliseconds exhibiting jitters of less than 2%, using VxWorks R , RTAI or Linux. Codes can also be developed and executed in Microsoft Windows R and Solaris R . This paper discusses the main design concepts of MARTe, in particular the architectural choices which enabled the combination of real-time accuracy, performance and robustness with complex and modular data driven applications.

2016-12-01

Full Text Available

Halfway through the 16th century in Spain the reading and interpretation of the Bible based on its original languages involved a very real danger for humanists who were seeking a better understanding of the Scriptures. The exclusive authority of the Latin Vulgate version declared by the Council of Trent in 1546 hindered the intellectual work of many Biblicists and Theologians, who were subjected to tight ideological control. In this context it must be considered the case of the Hebraist and scholar from the University of Salamanca, Martín Martínez de Cantalapiedra (1518-1579, who was prosecuted by the Inquisition of Valladolid in 1572 along with his colleagues Fray Luis de León and Gaspar de Grajal. All of them were accused of deviating from the genuine sense of the Vulgate in their more literal interpretations of the Masoretic text. The purpose of this article is to provide new evidence for the intellectual biography of Master Martínez de Cantalapiedra as well a to analyze the hermeneutical principles exposed during his inquisitorial in which he defended the Hebrew knowledge as an essential means of interpreting the Old Testament.

Performance Comparison of EPICS IOC and MARTe in a Hard Real-Time Control Application

Barbalace, Antonio; Manduchi, Gabriele; Neto, A.; De Tommasi, G.; Sartori, F.; Valcarcel, D. F.

2011-12-01

EPICS is used worldwide mostly for controlling accelerators and large experimental physics facilities. Although EPICS is well fit for the design and development of automation systems, which are typically VME or PLC-based systems, and for soft real-time systems, it may present several drawbacks when used to develop hard real-time systems/applications especially when general purpose operating systems as plain Linux are chosen. This is in particular true in fusion research devices typically employing several hard real-time systems, such as the magnetic control systems, that may require strict determinism, and high performance in terms of jitter and latency. Serious deterioration of important plasma parameters may happen otherwise, possibly leading to an abrupt termination of the plasma discharge. The MARTe framework has been recently developed to fulfill the demanding requirements for such real-time systems that are alike to run on general purpose operating systems, possibly integrated with the low-latency real-time preemption patches. MARTe has been adopted to develop a number of real-time systems in different Tokamaks. In this paper, we first summarize differences and similarities between EPICS IOC and MARTe. Then we report on a set of performance measurements executed on an x86 64 bit multicore machine running Linux with an IO control algorithm implemented in an EPICS IOC and in MARTe.

Burm, Jin Sik; Hwang, Jungil; Lee, Yung Ki

2018-04-01

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.

Full Text Available INTRODUÇÃO: A frequência cardíaca (FC no teste anaeróbio máximo de corrida (MART expressa o comportamento autonômico cardíaco em exercício. Ainda não foi investigado se tais respostas cronotrópicas apresentam associação com o desempenho aeróbio e anaeróbio. OBJETIVOS: Descrever a resposta cronotrópica cardíaca durante o MART nos segundos iniciais de estímulo (FC ON e de recuperação (FC OFF e estabelecer a associação entre as variáveis cronotrópicas com o desempenho aeróbio e anaeróbio. MÉTODOS: Foram voluntários 13 homens assintomáticos e fisicamente ativos, com 25,1 ± 4,9 anos, 76,8 ± 12,5 kg, 178,4 ± 9,0 cm e 50,6 ± 4,1 mL×kg‑1×min‑1. Na primeira visita, após a anamnese e medidas antropométricas, foi realizado um teste cardiopulmonar de exercício (TCPE com monitoração direta dos gases expirados. Na segunda visita, foi feita uma familiarização ao MART e na terceira, o teste de MART conduzido até a exaustão. RESULTADOS: A FC de recuperação (58 ± 20 bpm comparada à FC de pico alcançada no primeiro e no último estágio de MART (39 ± 14 bpm apresentou maior inclinação, resultando em maior amplitude de variação ao longo do teste, caracterizando diferenças significativas (P = 0,0017. A FC ON apresentou entre o momento inicial, meio e final do MART diferenças significativas (inicial versus final, p = 0,007. Para FC OFF foram encontradas diferenças significativas do início com o meio (p = 0,035 e do início com o final (p = 0,005 do teste. As correlações entre as variáveis cronotrópicas e de desempenho não apresentaram significância estatística (P < 0,05, assim como com as variáveis de desempenho. CONCLUSÃO: O MART parece ser um modelo de sobrecargas fisiológicas adequado para investigação da modulação autonômica cardíaca. Observou-se atuação do sistema parassimpático mesmo em cargas supramáximas até o final do teste.

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.)

Motion tracking-enhanced MART for tomographic PIV

International Nuclear Information System (INIS)

Novara, Matteo; Scarano, Fulvio; Batenburg, Kees Joost

2010-01-01

A novel technique to increase the accuracy of multiplicative algebraic reconstruction technique (MART) reconstruction from tomographic particle image velocimetry (PIV) recordings at higher seeding density than currently possible is presented. The motion tracking enhancement (MTE) method is based on the combined utilization of images from two or more exposures to enhance the reconstruction of individual intensity fields. The working principle is first introduced qualitatively, and the mathematical background is given that explains how the MART reconstruction can be improved on the basis of an improved first guess object obtained from the combination of non-simultaneous views reduced to the same time instant deforming the 3D objects by an estimate of the particle motion field. The performances of MTE are quantitatively evaluated by numerical simulation of the imaging, reconstruction and image correlation processes. The cases of two or more exposures obtained from time-resolved experiments are considered. The iterative application of MTE appears to significantly improve the reconstruction quality, first by decreasing the intensity of the ghost images and second, by increasing the intensity and the reconstruction precision for the actual particles. Based on computer simulations, the maximum imaged seeding density that can be dealt with is tripled with respect to the MART analysis applied to a single exposure. The analysis also illustrates that the maximum effect of the MTE method is comparable to that of doubling the number of cameras in the tomographic system. Experiments performed on a transitional jet at Re = 5000 apply the MTE method to double-frame recordings. The velocity measurement precision is increased for a system with fewer views (two or three cameras compared with four cameras). The ghost particles' intensity is also visibly reduced although to a lesser extent with respect to the computer simulations. The velocity and vorticity field obtained from a three

Previously, 19-Nor-2α-(3-hydroxypropyl-1α,25(OH2D3 (MART-10, the new brand 1α,25(OH2D3 analog, has been demonstrated to be an effective drug to inhibit HNSCC growth in vitro. Since most cancer patients die of metastasis, in this study, the antimetastatic effect of MART-10 on HNSCC was investigated. Our results reveal that both 1α,25(OH2D3 and MART-10 effectively repressed the migration and invasion of HNSCC cells, with MART-10 being much more potent than 1α,25(OH2D3. The antimetastatic effect of 1α,25(OH2D3 and MART-10 was mediated by attenuation of epithelial–mesenchymal transition (EMT, which was supported by the finding that the expression of EMT-inducing transcriptional factors, Sail and Twist, was inhibited by 1α,25(OH2D3 and MART

Modified geometrical optics of a smoothly inhomogeneous isotropic medium: The anisotropy, Berry phase, and the optical Magnus effect

International Nuclear Information System (INIS)

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

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

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.

The ODIN algorithm was already coded in previous works, but its integration in the real-time system has never been carried out at FTU. We illustrate how the MARTe architecture and the RTNet level allows for a first level of parallelization, distributing the data and/or time among nodes.

Highlights: • The paper describes the integration of two different frameworks for control and data acquisition. • It describes the way the two frameworks have been integrated. • It describes the advantages of this combined approach. • It presents a case study of the utilization of the two integrated frameworks. - Abstract: The recent long lasting fusion experiments introduced a change in paradigm for control and data acquisition. While formerly implemented by different systems, using different software and hardware solutions, new requirements, such as the need of handling a sustained data stream, the availability of powerful general-purpose computers and the evolution of Linux towards real-time responsiveness make an integrated solution nowadays feasible. In the fusion community several frameworks have been developed for control and data acquisition and some of them are shared among different experiments. In particular, MDSplus represents the most used framework for data acquisition and management and MARTe is a framework for real-time applications originally developed at JET, but then adopted in several other experiments. Neither system can be used alone to provide integrated real-time control and data acquisition but, since their functionality complements, they can be used in conjunction. To achieve this, an additional layer has been developed so that data handled in real-time by MARTe components can be redirected to pulse file for storage. At the same time, configuration data, typically defined in the MDSplus experiment model, can be seamlessly transferred to MARTe GAMs during system configuration.

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.

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

Science.gov (United States)

Sigusch, Volkmar

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.

En esta ocasión, se va mostrar de qué forma está impregnado el concepto de melancolía en su novela Amistad funesta. El análisis trata de ofrecer una nueva mirada sobre este texto gracias a la aplicación de las herramientas de la literatura comparada. Lucía Jerez se va a casar con su primo John, pero aparece Sol, una joven muy hermosa que hace estallar el conflicto entre los protagonistas. Tras el análisis de la historia de la melancolía en la literatura de Occidente, se comprueba cómo este concepto se mantiene arraigado en el Modernismo y, más concretamente, en esta obra de José Martí.

Efficient theory of dipolar recoupling in solid-state nuclear magnetic resonance of rotating solids using Floquet-Magnus expansion: application on BABA and C7 radiofrequency pulse sequences.

Science.gov (United States)

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.

Formal Verification Method for Configuration of Integrated Modular Avionics System Using MARTE

Directory of Open Access Journals (Sweden)

Lisong Wang

2018-01-01

Full Text Available The configuration information of Integrated Modular Avionics (IMA system includes almost all details of whole system architecture, which is used to configure the hardware interfaces, operating system, and interactions among applications to make an IMA system work correctly and reliably. It is very important to ensure the correctness and integrity of the configuration in the IMA system design phase. In this paper, we focus on modelling and verification of configuration information of IMA/ARINC653 system based on MARTE (Modelling and Analysis for Real-time and Embedded Systems. Firstly, we define semantic mapping from key concepts of configuration (such as modules, partitions, memory, process, and communications to components of MARTE element and propose a method for model transformation between XML-formatted configuration information and MARTE models. Then we present a formal verification framework for ARINC653 system configuration based on theorem proof techniques, including construction of corresponding REAL theorems according to the semantics of those key components of configuration information and formal verification of theorems for the properties of IMA, such as time constraints, spatial isolation, and health monitoring. After that, a special issue of schedulability analysis of ARINC653 system is studied. We design a hierarchical scheduling strategy with consideration of characters of the ARINC653 system, and a scheduling analyzer MAST-2 is used to implement hierarchical schedule analysis. Lastly, we design a prototype tool, called Configuration Checker for ARINC653 (CC653, and two case studies show that the methods proposed in this paper are feasible and efficient.

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

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

Science.gov (United States)

Okawa, Hirotada; Cardoso, Vitor

2014-11-01

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.

Highlights: • The integration of two frameworks for real-time control and data acquisition is described. • The integration may significantly fasten the development of system components. • The system includes also a code generator for the integration of code written in Simulink. • A real-time control systemcan be implemented without the need of writing any line of code. - Abstract: Simulink is a graphical data flow programming tool for modeling and simulating dynamic systems. A component of Simulink, called Simulink Coder, generates C code from Simulink diagrams. MARTe is a framework for the implementation of real-time systems, currently in use in several fusion experiments. MDSplus is a framework widely used in the fusion community for the management of data. The three systems provide a solution to different facets of the same process, that is, real-time plasma control development. Simulink diagrams will describe the algorithms used in control, which will be implemented as MARTe GAMs and which will use parameters read from and produce results written to MDSplus pulse files. The three systems have been integrated in order to provide a tool suitable to speed up the development of real-time control applications. In particular, it will be shown how from a Simulink diagram describing a given algorithm to be used in a control system, it is possible to generate in an automated way the corresponding MARTe and MDSplus components that can be assembled to implement the target system.

Literatura y filosofía: Sartre, Martín-Santos y Bartleby

Directory of Open Access Journals (Sweden)

Santamaría Pargada, Antonio

2006-04-01

Full Text Available Luis Martín Santos has been, after his soon death, one of the most unfairly forgotten Spanish intellectuals. This situation happens to be even more unjust considering the success of his novel “Time of Silence” and his unfinished “Time of Destruction”. The works of this psychiatrist, philosophically formed in the existentialism tradition, tackle from psychiatric and medical studies to interpretations of Dilthey, Jaspers and Heidegger. Maybe the most important achievement made by Dr. Martín-Santos was the fact of pooling in his novels all the different fields he worked in, namely: existential philosophy, psychiatry and literature. This mutual influence leads to a clearly existential interpretation of the narrative subject and to a nihilist conception of freedom: the nothingness completely understood as Sartre did. And, consequently, the attractiveness of approaching the Spanish author through literary theories that are close to the French contemporary philosophy and the primacy, not only of the existential analysis in literature, but also of the influence of the literary character as a fiction that is able to create possible realities. That is why it is interesting to study “Bartleby the Scrivener” as a paradoxical example of the existential nothingness made flesh. To put it in a nutshell, the existential triviality, a sign of modern times, has been indeed very successfully portrayed by Martín-Santos.Luis Martín-Santos ha sido, tras su temprana muerte, uno de los grandes olvidados entre los intelectuales españoles del franquismo. Olvido especialmente injusto, teniendo en cuenta el éxito de su novela Tiempo de Silencio y su interesante proyecto inacabado Tiempo de Destrucción.

Inconsciente genérico, feminismo y Nubosidad variable de Carmen Martín Gaite

Directory of Open Access Journals (Sweden)

Zecchi, Barbara

2006-08-01

Full Text Available In a context of marked tensions between gynocritics and contemporary Spanish women writers, Carmen Martín Gaite’s novel Nubosidad variable (Variable Cloud,1992 stands out as a curious paradox. As is well known, Martín Gaite repeatedly declared not to be a feminist and even scorned women who fought for equality between both sexes. This article argues that Nubosidad variable, however, constitutes one of the best examples of a consciously feminist text. In this novel Martín Gaite applies some of the most prominent paradigms of feminist literary theory, such as the construction of a non-linear and a-chronological narration (Julia Kristeva, the attempt to create a “language of the body” (Helène Cixous, the foregrounding of a mother-daughter bond (Luisa Muraro, as well as the use of female writing as a means of self-discovery (Elaine Showalter.En un contexto de falta de comunicación entre ginocrítica y escritura femenina, la novela Nubosidad variable (1992 de Carmen Martín Gaite se presenta como una significativa paradoja. Si por un lado su autora declaró repetidas veces no ser feminista —y hasta menospreció con ironía a las mujeres que han luchado por la igualdad—, Nubosidad variable es una innegable aplicación de algunos de los más conocidos paradigmas de la teoría literaria feminista. Desde la narración no-lineal y atemporal que sigue el “tiempo de las mujeres” de Julia Kristeva, hasta el intento de crear una lengua del cuerpo a lo Hélène Cixous; desde el vínculo madre-hija teorizado por Luisa Muraro, hasta la escritura femenina como auto-descubrimiento de Elaine Showalter, esta novela representa uno de los mejores ejemplos, dentro de la narrativa contemporánea española, de lo que llamaría un texto conscientemente feminista.

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

International Nuclear Information System (INIS)

Huggins, E.R.

1994-01-01

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.

Sus anotaciones son comparadas con las de José Martí, percibiendo que mientras que la poesía era para Martí la forma suprema de la literatura, para Lezama llegó a ser un método de conocimiento de la realidad, la categoría central a la que conduce su pensamiento estético. Se pretende demostrar además cómo Lezama parte de las ideas de Martí sobre la poesía para llegar a tener ideas propias y luego trascendentes.   This article studies what are known as the Diaries of poet José Lezama Lima, in which his notes taken between 1939-1949 and 1956-1958 are gathered in order to analyze how both texts reflect his interest towards poetry as well as his reflections about it. His notes are compared with those of José Martí, revealing the fact that whereas for Martí, poetry was the supreme manifestation of literature; Lezama saw it as a method for acquiring knowledge of reality, the central category to which his aesthetic thinking leads. An attempt is made to further showcase the fact that Lezama starts off with Martí's ideas about poetry in order to later develop his own, which would at a later date become transcendental.

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

Directory of Open Access Journals (Sweden)

Jonathan Monroe

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.

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.

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

Denisov, S. I.; Lyutyy, T. V.; Reva, V. V.; Yermolenko, A. S.

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.

Boundary layer stability on a yawed spinning body of revolution and its effect on the magnus force and moment

Science.gov (United States)

Jacobson, I. D.; Morton, J. B.

1972-01-01

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.

2014-06-01

Full Text Available The fruits of asaí (Euterpe precatoria Mart. are a traditional food for Amazonian inhabitants who harvest it from wild populations, employing management practices that affect palm populations and productivity. Here we present management data on fruit harvesting in a Tikuna community in the Colombian Amazon. We identified the market structure in Leticia and evaluated the population structure and fruit productivity in a scarcely harvested forest and a heavily harvested one. We performed interviews to determine management and market practices and we established plots to identify population structure and productivity. Harvesting is mostly for self-supply and palm felling is the main method. The fruits are mostly consumed and marketed as juice. The asaí market is small and seasonal but it represents an important source of income for many, mainly indigenous, families. The population density was 1 680 individuals and 248 adults/ha in San Martín de Amacayacu, where harvesting was from 2 % of all adult palms, and 916 individuals and 30 adults/ha in Leticia, where harvesting was from 23 % of all adult palms. The population structure in both sites followed an in-verted J-curve in which the majority of the individuals were seedlings. Productivity was 2.2 ton/ha/ year in San Martín de Amacayacu and 0.33 ton/ha/ year in Leticia. The population in Leticia is heavily harvested to supply the local market and the consequences of this use are a reduction in population density and fruit productivity and a low abundance of individuals in all size classes.

Full Text Available Kielmeyera coriacea Mart., known as “pau-santo”, is mentioned in the literature as the main tree species which produces cork of the Brazilian Cerrado. The purpose of this study was to describe the morphological aspect of Kielmeyera coriacea (“pau-santo” cork cells through its microscopic structure and to compare it with the cellular morphology of Quercus suber (cork oak, which is the main cork producing species worldwide. The bark from three trees of the species Kielmeyera coriacea Mart. was collected randomly at points 1.30 m above the ground, with four repetitions per sample. Samples came from native stands situated in the region of Luminárias - MG, Brazil. The study of morphological characteristics was conducted by counting the number of sides of the cells, and measuring the dimensions of the cells from images obtained by scanning electron microscopy (SEM. Images were analyzed using the LEOUIF software. The distribution in faces and edges of cork cells from Kielmeyera coriacea, was observed to have from 4 to 8 sides, with a predominance of hexagonal cells, similar to Quercus suber. The averages of height and thickness of the cell walls were 40 to 70 µm and 1.5 to 2.0 µm respectively, indicating cells from an early growth season. Both height and thickness were observed to be greater than those present in Quercus suber

The coming electric Wal-Mart

International Nuclear Information System (INIS)

Drzemiecki, J.H.; Augustini, P.

1993-01-01

Market power in the competitive electric marketplace will depend on being a low-price leader. Electric utility executives are beginning to peer over the wall into the emerging world of competitive electric markets. Many will be terrified by the uncertainties and disorder associated with new service offerings such as retail wheeling and the transformation of other vestiges of the vertically integrated electric monopolies known for the past 100 years. The potential for increased competition for retail customers promises to have as fundamental an effect on the electric utility industry as Wal-Mart has had on retailing. Firms that are prepared for the new competitive environment will be in the strongest position to respond to the marketplace; those that are not prepared might want to consider the fate of the corner five-and-dime. To remain competitive, utility executives must take proactive steps to redefine their vision of their company's future. Such a redefinition must include a candid assessment of the strategies to be taken to reposition their firm to succeed, not just within the existing service area but in multiple markets

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

Science.gov (United States)

Hellman, Kevin M; Mendelson, Scott J; Mendez-Duarte, Marco A; Russell, James L; Mason, Peggy

2009-11-01

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.

Automated quantification of proliferation with automated hot-spot selection in phosphohistone H3/MART1 dual-stained stage I/II melanoma.

Staging of melanoma includes quantification of a proliferation index, i.e., presumed melanocytic mitoses of H&E stains are counted manually in hot spots. Yet, its reproducibility and prognostic impact increases by immunohistochemical dual staining for phosphohistone H3 (PHH3) and MART1, which also may enable fully automated quantification by image analysis. To ensure manageable workloads and repeatable measurements in modern pathology, the study aimed to present an automated quantification of proliferation with automated hot-spot selection in PHH3/MART1-stained melanomas. Formalin-fixed, paraffin-embedded tissue from 153 consecutive stage I/II melanoma patients was immunohistochemically dual-stained for PHH3 and MART1. Whole slide images were captured, and the number of PHH3/MART1-positive cells was manually and automatically counted in the global tumor area and in a manually and automatically selected hot spot, i.e., a fixed 1-mm(2) square. Bland-Altman plots and hypothesis tests compared manual and automated procedures, and the Cox proportional hazards model established their prognostic impact. The mean difference between manual and automated global counts was 2.9 cells/mm(2) (P = 0.0071) and 0.23 cells per hot spot (P = 0.96) for automated counts in manually and automatically selected hot spots. In 77 % of cases, manual and automated hot spots overlapped. Fully manual hot-spot counts yielded the highest prognostic performance with an adjusted hazard ratio of 5.5 (95 % CI, 1.3-24, P = 0.024) as opposed to 1.3 (95 % CI, 0.61-2.9, P = 0.47) for automated counts with automated hot spots. The automated index and automated hot-spot selection were highly correlated to their manual counterpart, but altogether their prognostic impact was noticeably reduced. Because correct recognition of only one PHH3/MART1-positive cell seems important, extremely high sensitivity and specificity of the algorithm is required for prognostic purposes. Thus, automated

The socioeconomic context of the use of Euterpe precatoria Mart. and E. oleracea Mart. in Bolivia and Peru.

Traditional knowledge (TK) has enabled communities to adapt to changes in life conditions over centuries. However, this local context is being dramatically affected by recent changes through globalization and modernization of societies. In this paper we seek to identify socio-economic factors that are related to the knowledge and use of two palm species in mestizo and indigenous communities in the Amazonian of Peru and Bolivia. Both species are known in the region under the main vernacular name of Asaí, and are source of two highly commercialized resources: palm-hearts and fruits. Euterpe precatoria Mart. is native to the region whereas E. oleracea Mart. is being introduced for the use of both resources. We compare TK about the two Euterpe species in both countries in relation to 14 socioeconomic factors in seven use categories. We performed a Multivariate analysis of variance (MANOVA) to elucidate the influence of each socioeconomic factor on the overall palm knowledge or on individual use categories. In the two countries, we found that mestizos, speaking only Spanish, and migrants in the same ecoregion, knew more uses in all use categories for E. precatoria than for E. oleracea, even in use categories such as Medicinal and veterinary and Construction, for which indigenous participants had more uses in case of other species. In Peru, the use of E. precatoria was higher among participants with greater wealth, which could be related to the commercial importance that both the fruits and the palm-hearts have had in the markets of the region. In contrast, in Bolivia, although some income generation from Euterpe sp. was observed, the use of E. precatoria was much more homogeneously distributed. The use of E. oleracea in Bolivia is recent, and although its most important uses are related to the consumption of fruits and palm-hearts (Human food), it is now being slowly used for Medicinal and Construction purposes, similar to E. precatoria. The use of each of the species

Full Text Available In this study, we aimed to determine lignified tissue in young stems of Struthanthus vulgaris Mart. by infrared microspectroscopy and histochemical methods as well as by fluorescence microscopy. Struthanthus vulgaris Mart. is a mistletoe species that belongs to the Loranthaceae family. A brief anatomical description was also carried out. The first procedure for analysis was to elaborate anatomical cross sections (20-30 µm from young stems before and after treatment with NaOH 1%. This procedure was applied to release possible low molecular mass phenolic compounds. Safranin-astra blue was used to distinguish anatomical tissues while Wiesner test enabled verification of lignified pericyclic fibers. Infrared microspectroscopy analysis confirmed the presence of lignin in this region according to the following spectral signals: 1600 (shoulder, 1511, 1453, 1338 and 1244 cm-1. Analyses of the cross section of young stems under fluorescence microscopy before and after treatment with NaOH 1% allowed us to confirm the presence of low mass phenolic compounds in the region of pericyclic fibers.

After leaving Spain and settling in New York, she became a successful fashion designer, and seemed happy and easy-going. The bond with memory and the past is the main topic of this novel, as it is in most of Martín Gaite’s production. The window on the past that Amparo closed moving to the US suddenly reappears when she needs to discover herself and her origins. This inconvenience in an anonymous life brings huge changes that will condition her and her loved ones. Travelling to Spain and interacting with places and people connected with her childhood, Amparo goes through the window she had closed forty years before, restoring the order. The window connects the present and the past, symbolizes the emigrant’s transience, personified in the novel by Amparo, who can definitely find the lost serenity and heart’s-ease.

Full Text Available While Ezequiel Martínez Estrada writes Marta Riquelme, between his fiction and essays, and Victoria Ocampo begins to write her memories; it arises from both an emotional and intellectual relationship through letters along more than 15 years since the late '40s and until the death of Martinez Estrada in 1964. This article will discuss much of those letters with the intended to show that one of the central axes of the epistolary is the construction by Martínez Estrada, his interlocutor in a character: writer women who acquire multiple identities including Marta Riquelme looks.

A psychology of liberation for Central America: the unfinished work of Ignacio Martín-Baró (1942-1989).

Gondra, José María

2013-01-01

On November 16, 1989 the world was shocked by the news of the assassination of six Jesuits at the campus of the Universidad Centro Americana José Simeón Cañas (UCA) in San Salvador, El Salvador. Among those murdered by government soldiers was Ignacio Martín-Baró, a PhD in social psychology from the University of Chicago who at that time was the Vice-Rector for Academic Affairs and Vice-President of the Interamerican Society of Psychology (SIP). Drawing on Martín-Baró's published writings and non-published academic papers and correspondence, this article traces the evolution of the Spanish-born Jesuit who became a leading authority among Latin American social psychologists. In particular, it analyzes his project of becoming a clinical psychologist under the influence of psychoanalysis, his critical social psychology aimed to "de-ideologize" the oppressed social classes of El Salvador, and his ultimate project of a psychology of liberation for Latin America. Martín-Baró's work came to a tragic end just when it began to bear fruit, but it stands as a testimony to a lifetime committed to the human values of democracy, social justice and service to society's poorest and most neglected.

La conmemoración de las Independencias hispanoamericanas en José Martí: El intelectual moderno y la guerra

Directory of Open Access Journals (Sweden)

Susana Emilce Zanetti

2010-11-01

Full Text Available Bolívar, San Martin and Páez are the only Independence protagonists to whom Martí devotes his celebratory speeches and chronicles. Those texts were published throughout a decade [from 1883 to 1894], exactly when Latin American political and cultural leaders regard themselves as having the right to establish [not without dispute] those "places of memory" [in the sense of Nora 2003] which monumentalize a recent heroic history. The texts by Martí are interesting in this sense: facing the imminent fight for the independence of Cuba, his evocation of past heroic deeds acquires a special symbolic value. It assumes the return to a finished era but from which ethical, social and political key values for the present must be extracted. Martí encourages the cult of the heroes but, at the same time, he imposes specific and divergent meanings. He celebrates the heroic deed but also emphasizes the bond between the leaders and the people, by pointing out the authority of both of them in materializing independency and the exclusion of the latter from the processes of modernization. And also, in his assessment, he warns about the errors of the leaders linked to the 'blindness of power'

Defensa de lo local en Nuestra América y Coney Island de José Martí: el ensayo como un espacio para la ideología dentro de las raíces hispanoamericanas

Full Text Available José Martí proposes that for the proper development of the Republic in America it is essential to secure a government that has as the premises of its administration the natural categories of its origin. To evaluate the local characteristics Martí was thinking of I will carry out an analysis of two of his essays: Nuestra América (Martí, 1977 and Coney Island (Martí, 1881, in an attempt to unravel the polarisation strategy which supports his argument. Indeed, through a semantic axis the author places the concepts of nature and interiority over external and foreign, making a parallel between what he calls “natural men in America” and those who represent the “other”, the people of the United States. In this way, it will be possible to see how Martí will question the alleged hegemony of the northern country, claiming the primitive qualities of American indigenous peoples, to condition the problem of allocation of barbarism. The main theoretical framework to address this work is the use of the theories of discourse analysis of Teun van Dijk, which will serve me to develop and analyse the semantic axis that Martí creates in the works studied.José Martí propone que para el buen desarrollo de la República en América es indispensable un gobierno que fije como premisas para su administración las categorías naturales y autóctonas de su origen. Para apreciar cuáles son las características locales pensadas por Martí llevaré a cabo un análisis de dos de sus ensayos: Nuestra América (Martí, 1977 y Coney Island (Martí, 1881, con la intención de desentrañar la estrategia de polarización que da sustento a su argumentación. En efecto, el autor a través de un eje semántico sitúa los conceptos de naturaleza e interioridad por sobre lo externo y lo foráneo, realizando un paralelo entre lo que él llama “los hombres naturales de América” y aquellos que representarían a los “otros”, es decir a los habitantes de los

Full Text Available Este trabalho utiliza um método de processamento digital de imagens para detecção de feições eólicas na superfície de Marte.  Essas feições são rastros de vórtices convectivos recorrentes em Marte, estes, por sua vez, são formados por correntes de ar quente instáveis, próximas à superfície, provocadas por insolação. A área de estudo escolhida foi Thaumasia. O método aplicado baseia-se na teoria da Morfologia Matemática, sendo os rastros obtidos de maneira automática via processamento digital de imagens e binarização automática pelo método de otsu restrito. Os rastros foram detectados automaticamente nas imagens orbitais, o que permitiu calcular características importantes dos vórtices como: largura média e máxima, área de recobrimento, direção preponderante entre outros. Os resultados podem ser usados para auxiliar na compreensão do fenômeno que ocorre no ambiente marciano, contribuindo para o entendimento de como os vórtices de dust devils podem influenciar nas variações locais climáticas do planeta e se faz importante por ser o processo geológico em maior atividade no planeta.

A method of self-pursued boundary value on a body and the Magnus effect calculated with this method

Yoshino, Fumio; Hayashi, Tatsuo; Waka, Ryoji

1991-03-01

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.

Distinct effect of orphanin FQ in nucleus raphe magnus and nucleus reticularis gigantocellularis on the rat tail flick reflex.

Science.gov (United States)

Yang, Z; Zhang, Y; Wu, G

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.

An analysis of natural ventilation techniques to achieve indoor comfort in Wal-Mart express

Science.gov (United States)

O'Dea, Shona

Despite global efforts to reduce world fossil fuel dependency the world still obtains 81% of its energy from fossil fuels (IEA,2009). Modern renewable alternatives have been around since the mid twentieth century these alternatives have not been integrated into electrical grid systems at the exponential rate required to eradicate fossil fuels dependency. The problem, world energy demand, is too large to be satisfied by anything other than the energy-dense fossil fuels used today. We must change our energy intensive processes in order to conserve energy and hence reduce the demands that alternatives must satisfy. This research aims to identify sustainable design opportunities through the application of innovative technologies for the largest retailer in the US with the view that a viable conservative design measure could be applied to the store model, which is replicated across the country, causing a cumulative and hence larger impact on the company energy consumption as a whole. This paper will present the literature available on the 'big box' industry and Wal-Mart, comfort, natural ventilation and building simulation software and then perform an analysis into the viability of naturally ventilating the Wal-Mart Express sales zone using Monodraught natural ventilation windcatcher products

Heterogeneity of Metastatic Melanoma:  Correlation of MITF With Its Transcriptional Targets MLSN1, PEDF, HMB-45, and MART-1.

Histologic and molecular heterogeneity is well recognized in malignant melanoma; however, the diversity of expression of new and classic melanoma markers has not been correlated in serial sections of metastases. We examined and correlated the expression of microphthalmia transcription factor (MITF) with its transcriptional targets, including melastatin (MLSN1/TRPM1), pigment epithelium-derived factor (SERPINF1/PEDF), SILV/PMEL17/GP100 (human melanoma black 45 [HMB-45]), and melanoma antigen recognized by T cells 1 (MART-1)/MLANA, in 13 melanoma metastases in lymph nodes of 13 patients. The expression levels and patterns of marker expression were recorded by a semiquantitative, 4-point ordinal reactivity method. Our results showed a consistently robust and diffuse expression of MITF protein in 12 (92%) of 13 metastatic tumors compared with variable expression of MLSN1 (46%) messenger RNA or PEDF (75%), HMB-45 (54%), and MART-1 (46%) proteins. Overall, in melanoma lymph node metastases, MITF protein expression was not tightly correlated with its gene targets. Moreover, the immunoreactivity for MITF, compared with MART-1 and HMB-45, was retained, supporting immunohistochemical detection of MITF as a more sensitive method of detecting metastatic melanoma. © American Society for Clinical Pathology, 2016.

Little is known about the practices for stocking and procuring healthy food in non-traditional food retailers (e.g., gas-marts, pharmacies). The present study aimed to: (i) compare availability of healthy food items across small food store types; and (ii) examine owner/manager perceptions and stocking practices for healthy food across store types. Descriptive analyses were conducted among corner/small grocery stores, gas-marts, pharmacies and dollar stores. Data from store inventories were used to examine availability of twelve healthy food types and an overall healthy food supply score. Interviews with managers assessed stocking practices and profitability. Small stores in Minneapolis and St. Paul, MN, USA, not participating in the Special Supplemental Nutrition Program for Women, Infants, and Children. One hundred and nineteen small food retailers and seventy-one store managers. Availability of specific items varied across store type. Only corner/small grocery stores commonly sold fresh vegetables (63% v. 8% of gas-marts, 0% of dollar stores and 23% of pharmacies). More than half of managers stocking produce relied on cash-and-carry practices to stock fresh fruit (53%) and vegetables (55%), instead of direct store delivery. Most healthy foods were perceived by managers to have at least average profitability. Interventions to improve healthy food offerings in small stores should consider the diverse environments, stocking practices and supply mechanisms of small stores, particularly non-traditional food retailers. Improvements may require technical support, customer engagement and innovative distribution practices.

In this paper we suggest a design of a web marketplace where users of scientific application software and databases, presented in the form of web services, as well as their providers will have presence simultaneously. The model, which will be the basis for the web marketplace is close to the customer-to-customer (C2C) model, which has been successfully used, for example, on the auction sites such as eBay (ebay.com). Unlike the classical model of C2C the suggested marketplace focuses on application software in the form of web services, and standardization of API through which application software will be integrated into the web marketplace. A prototype of such a platform, entitled eSciMart, is currently being developed at SINP MSU.

José Martí e los indios de Norteamérica: mediazione culturale e «scontro di civiltà». Una rilettura critica

Directory of Open Access Journals (Sweden)

Alessandro Badella

2010-01-01

Full Text Available The Cuban poet José Martí, “Master of the Americas” as pointed out by a famous Italian study by Carlo Batà, was probably the most important South American thinker of the two last decades of the Nineteenth century. This essay deals with the importance of “civilization clash” between US positivism - or WASP-ism - and the last resistances of Native Americans' cultural heritage during his personal experience as an exile in the United States. Martí, in this racial struggle and racist instincts, experienced a dual vision about the “Indian problem” in the Americas. In his first essays he focused on the positivistic view, really common among Latin American cultural élites (from Alberdi to Sarmiento, which depicted the Indian people as the burden of creole and white race in the path toward progress.On the other hand, as appeared clearly in Escenas americanas, the Cuban analysed more precisely the American struggle between civilization and savagery. In the cultural massacre inflicted to Indian tribes, he saw the real savagery in American civilization. So, this reflection paved the way to a new approach in considering the possibility of importing the Anglo-saxon model of civilization and political structures to the liberated Cuba after the independence (but also to continental Latin America.This relationship let us understand some interesting features in Martí's huge cultural production. We are introduced to the very essence of his cultural mediation between those two different lifestyles and models of civilization. This mediation would have represented a new way of intending North vs South America struggles or even Western way of life vs different ones, considered “barbarous” from the first.In our modern times, in which the terms “exporting values” or “civilization clash” seem to be very common in usage, it is really stimulating discover that the same problem was posed by Martí more than one century ago.

The recent identification of genes encoding melanoma-associated antigens has opened new possibilities for the development of cancer vaccines designed to cause the rejection of established tumors. To develop a syngeneic animal model for evaluating antigen-specific vaccines in cancer therapy, the murine homologues of the human melanoma antigens MART1 and gp 100, which were specifically recognized by tumor-infiltrating lymphocytes from patients with melanoma, were cloned and sequenced from a murine B16 melanoma cDNA library. The open reading frames of murine MART1 and gp 100 encode proteins of 113- and 626-amino acids with 68.8 and 77% identity to the respective human proteins. Comparison of the DNA sequences of the murine MART1 genes, derived from normal melanocytes, the immortalized nontumorgenic melanocyte line Melan-a and the B16 melanoma, showed all to be identical. Northern and Western blot analyses confirmed that both genes encoded products that were melanocyte lineage proteins. Mice immunized with murine MART1 or gp 100 using recombinant vaccinia virus failed to produce any detectable T-cell responses or protective immunity against B16 melanoma. In contrast, immunization of mice with human gp 100 using recombinant adenoviruses elicited T cells specific for hgp100, but these T cells also cross reacted with B16 tumor in vitro and induced significant but weak protection against B16 challenge. Immunization with human and mouse gp100 together [adenovirus type 2 (Ad2)-hep100 plus recombinant vaccinia virus (rVV)-mgp100], or immunization with human gp100 (Ad2-hgp100) and boosting with heterologous vector (rVV-hgp100 or rVV-mgp100) or homologous vector (Ad2-hgp100), did not significantly enhance the protective response against B16 melanoma. These results may suggest that immunization with heterologous tumor antigen, rather than self, may be more effective as an immunotherapeutic reagent in designing antigen-specific cancer vaccines.

Distributions of radioactivity and natural radionuclides in water, sediment and eichornia crassipes (mart) solms from Surabaya River and coastal area have been evaluated. Five sampling locations were selected to represent fresh water and coastal water environment. The samples consist of water (fresh & coastal), bottom surface sediment and eichornia crassipes (mart) solms. The result showed that the gross-β activity from water environment were lower than the threshold value of Environmental Minister Act. Kep.02/MENKLH/I/1988 (1000 mBq/L) and indicated that β-radio ecological quality of water were still good. But the activity of the gross-α of water environment were higher than the threshold value of Environmental Minister Act. Kep.02/MENKLH/I/1988 (100 mBq/L). The eichornia crassipes (mart) solms (gross) activity were higher than water and sediment activities and indicated that transfer of radio nuclides from water to sediment and organism can be detected in water environment. Two natural radionuclide can be identified by γ-Spectrometric technique, they were K"4"0 and Tl"2"0"8. Generally the distribution factors F_D were smaller than bioaccumulation factor F_B. (author)

Decoction of roots of the Amazonian palm acai (Euterpe precatoria Mart.) is widely used by Brazilian and Peruvian people as an anti-inflammatory, to heal kidney and liver diseases and against snake bites. In this study, the antioxidant activity of extracts and flavonoids (quercetin, catechin, epicatechin, rutin and astilbin) isolated from roots and leaf stalks of E. precatoria was investigated using β-carotene in TLC plates and DPPH radical scavenging in a spectrophotometric bioassay. All extracts and flavonoids showed activity. Also, the cytotoxic activity of these extracts was evaluated by the brine shrimp (Artemia salina) larvicide bioassay and was lower than that of lapachol, used as control. The presence of flavonoids and sitosterol-3-O-β-D-glucopyranoside in the extracts can justify the use of the plant in traditional medicine. (author)

The philologist Pedro Martínez López: an imaginative liberal lampoonist | El filólogo Pedro Martínez López: un libelista liberal imaginativo

Aline Vauchelle-Haquet

2006-12-01

Full Text Available In 1830, the philologist Pedro Martínez López was forced to go into exile in France for political reasons. In 1832, he published Representación a Fernando VII, rey de España, a lampoon in which he made a whole string of accusations against the tyrant. At the end of the following year, he published España en 1833, al expirar Fernando VII, another lampoon in which he blamed the king's despotic reign for the country's disastrous situation and asserted that such abuses and injustices could only be remedied by re-establishing the Constitution of Cádiz of 1812. In 1834, he ceased to rail against his political enemies, changed strategy, and using his considerable imagination, wrote a kind of fable entitled Una noche en el infierno, vista entre sueños. With a mixture of humour and acid wit, it told of how all the devils in the Kingdom of Darkness, embracing the «sacred» cause of liberalism, vented their anger on the deceased Ferdinand and his followers, who were still in power. It would appear that the work was a success, since it was republished in 1836. In 1835, disillusioned with the tepid and conservative liberal regime of the Estatuto Real, Martínez López wrote another story, Las Brujas en Zugarramurdi, in which different satanic creatures, this time sorceresses, take it upon themselves to defeat moderantismo and establish a progressive regime.

Distribution of radioactivity and natural radionuclide in water, sediment and eichornia crassipes (mart) sloms from Surabaya river and coastal area have been evaluated. Five sampling locations were selected to represent fresh water and coastal water environment. The samples consist of water (fresh and coastal), bottom surface sediment and eichornia crassipes (mart) sloms The result showed that the gross-β activity from water environment were lower than the threshold value of Environmental Minister Act. Kep.02/MENKLH/I/1988 (1000 mBq/L) and indicated that β-radioecological quality of water were still good. But the activity of the gross-α of water environment were higher than the threshold value of Environmental Minister Act. Kep.02/MENKLH/I/1988 (100 mBq/L). The eichornia crassipes (mart) sloms (gross) activity were higher than water and sediment activities and indicated that transfer of radionuclides from water to sediment and organism can be detected in water environment. Two natural radionuclides can be identified by γ-Spectrometric technique, they were K-40 and TI-208. Generally the distribution factor F D were smaller than bioaccumulation factor F B . (author)

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

Science.gov (United States)

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.

A field prototype of an antibody array-based life-detector instrument, Signs Of LIfe Detector (SOLID2), has been tested in a Mars drilling mission simulation called MARTE (Mars Astrobiology Research and Technology Experiment). As one of the analytical instruments on the MARTE robotic drilling rig, SOLID2 performed automatic sample processing and analysis of ground core samples (0.5 g) with protein microarrays that contained 157 different antibodies. Core samples from different depths (down to 5.5 m) were analyzed, and positive reactions were obtained in antibodies raised against the Gram-negative bacterium Leptospirillum ferrooxidans, a species of the genus Acidithiobacillus (both common microorganisms in the Río Tinto area), and extracts from biofilms and other natural samples from the Río Tinto area. These positive reactions were absent when the samples were previously subjected to a high-temperature treatment, which indicates the biological origin and structural dependency of the antibody-antigen reactions. We conclude that an antibody array-based life-detector instrument like SOLID2 can detect complex biological material, and it should be considered as a potential analytical instrument for future planetary missions that search for life.

Historical biogeography sets the foundation for contemporary conservation of martens (genus Martes) in northwestern North America

Effective conservation of insular populations requires careful consideration of biogeography, including colonization histories and patterns of endemism. Across the Pacific Northwest of North America, Pacific martens (Martes caurina) and American pine martens (Martes americana) are parapatric sister species with distinctive postglacial histories. Using mitochondrial DNA and 12 nuclear microsatellite loci, we examine processes of island colonization and anthropogenic introductions across 25 populations of martens. Along the North Pacific Coast (NPC), M. caurina is now found on only 2 islands, whereas M. americana occurs on mainland Alaska and British Columbia and multiple associated islands. Island populations of M. caurina have a longer history of isolation reflected in divergent haplotypes, private microsatellite alleles, and relatively low within-population diversity. In contrast, insular M. americanahave lower among-population divergence and higher metrics of within-population diversity. On some NPC islands, introductions of M. americana may be related to decline of M. caurina. Long-term persistence of these species likely has been influenced by anthropogenic manipulations, including wildlife translocations and industrial-scale deforestation, yet, the distinctive histories of these martens have not been incorporated into natural resource policies.

[On the quest for the right way--life and work of Magnus Schmid (1918-1977), historian of medicine].

Science.gov (United States)

Mildenberger, Florian

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.

Fur-rubbing with Piper leaves in the San Martín titi monkey, Callicebus oenanthe

Full Text Available We report observations on fur-rubbing with leaves from Piper aduncum by a San Martín titi monkey, Callicebus oenanthe. Fur-rubbing occurred during the transition from the dry to the rainy season in a titi monkey group living in a forest fragment in the Moyobamba region of Peru. Since Piper leaves include very potent compounds that may affect ectoparasites, we tentatively interpret the observed fur-rubbing as self-medication.

Data mart construction based on semantic annotation of scientific articles: A case study for the prioritization of drug targets.

Science.gov (United States)

Teixeira, Marlon Amaro Coelho; Belloze, Kele Teixeira; Cavalcanti, Maria Cláudia; Silva-Junior, Floriano P

2018-04-01

Semantic text annotation enables the association of semantic information (ontology concepts) to text expressions (terms), which are readable by software agents. In the scientific scenario, this is particularly useful because it reveals a lot of scientific discoveries that are hidden within academic articles. The Biomedical area has more than 300 ontologies, most of them composed of over 500 concepts. These ontologies can be used to annotate scientific papers and thus, facilitate data extraction. However, in the context of a scientific research, a simple keyword-based query using the interface of a digital scientific texts library can return more than a thousand hits. The analysis of such a large set of texts, annotated with such numerous and large ontologies, is not an easy task. Therefore, the main objective of this work is to provide a method that could facilitate this task. This work describes a method called Text and Ontology ETL (TOETL), to build an analytical view over such texts. First, a corpus of selected papers is semantically annotated using distinct ontologies. Then, the annotation data is extracted, organized and aggregated into the dimensional schema of a data mart. Besides the TOETL method, this work illustrates its application through the development of the TaP DM (Target Prioritization data mart). This data mart has focus on the research of gene essentiality, a key concept to be considered when searching for genes showing potential as anti-infective drug targets. This work reveals that the proposed approach is a relevant tool to support decision making in the prioritization of new drug targets, being more efficient than the keyword-based traditional tools.

MART-10, a New Generation of Vitamin D Analog, Is More Potent than 1α,25-Dihydroxyvitamin D3 in Inhibiting Cell Proliferation and Inducing Apoptosis in ER+ MCF-7 Breast Cancer Cells

Directory of Open Access Journals (Sweden)

Kun-Chun Chiang

2012-01-01

Full Text Available Hormone antagonist therapy for estrogen receptor positive (ER+ breast cancer patients post radical surgery and radiation therapy has a poor prognosis and also causes bone loss. 1α,25-dihydroxyvitamin D3 [1α,25(OH2D3] is a potent antitumor agent in pre-clinical studies, but caused hypercalcemia when its effective antitumor doses were used. Therefore, we investigated the effects of a less-calcemic 1α,25(OH2D3 analog, 19-nor-2α-(3-hydroxypropyl-1α,25-dihydroxyvitamin D3 (MART-10, on ER+MCF-7 cells. We demonstrate that MART-10 is 500- to 1000-fold more potent than 1α,25(OH2D3 in inhibiting cell growth in a dose- and time-dependent manner. MART-10 is also much more potent in arresting MCF-7cell cycle progression at G0/G1 phase as compared to 1α,25(OH2D3, possibly mediated by a greater induction of p21 and p27 expression. Moreover, MART-10 is more active than 1α,25(OH2D3 in causing cell apoptosis, likely through a higher BAX/Bcl expression ratio and the subsequent cytochrome C release from mitochondria to cytosol. Based on our in vitro findings, MART-10 could be a promising vitamin D analog for the potential treatment of breast cancer, for example, ER+ patients, to decrease the tumor relapse rate and the side effect on bone caused by antihormone regimens. Thus, further in vivo animal study is warranted.

MART-1, Melan-A, and Tyrosinase have shown encouraging results for evaluation of melanoma micrometastases in sentinel lymph nodes, as compared to conventionally used S-100 protein and HMB-45. To achieve higher sensitivity, some studies recommend evaluation of three sections, each at intervals of 200 μ. This would mean, routine staining of three adjacent sections in each of the three clusters at intervals of 200 μ, requiring nine slides resulting in added expense. If a cocktail of these antibodies could be used, only one section would be required instead of three generating significant cost savings. We prepared a combination of monoclonal antibodies to these three immunomarkers in optimized dilutions (MART-1, clone M2-7C10, dilution 1:500; Melan-A, clone A103, dilution 1:100; and Tyrosinase, clone T311, dilution 1:50) and designated it as 'MCW melanoma cocktail'. Formalin-fixed paraffin-embedded tissue sections of sentinel lymph nodes from patients with cutaneous melanoma, without macro-metastases were evaluated with this cocktail. Melanoma micrometastases were easily detectable with the cocktail in 41 out of 188 slices (8/24 cases). The diagnostic accuracy amongst five pathologists did not show statistically significant difference. Out of 188 slices, 78 had adjacent sections immunostained individually with MART-1 and Melan-A during our previous study. Of these 78 slices, 21 were positive for melanoma micrometastases with MART-1 and Melan-A individually. However, the adjacent section of these slices immunostained with the cocktail detected metastases in four additional slices. Thus, MART-1 and Melan-A could not detect melanoma micrometastases individually in 16% (4/25) of slices positive with the cocktail. Benign capsular nevi were immunoreactive for the cocktail in 4.8% (9/188) slices. All 81 slices of negative test controls (sentinel lymph nodes of mammary carcinoma) were interpreted correctly as negative for melanoma micrometastases. The melanoma

Full Text Available José Julián Martí Pérez, Héroe Nacional de Cuba, nació el 28 de enero de 1853. Su ideario pedagógico lo encontramos presente en muchas de sus publicaciones, como son: crónicas periodísticas, cartas y la Revista La Edad de Oro. Martí recogió una valiosa herencia pedagógica de avanzada, representada en Félix Varela, José de la Luz y Caballero, Rafael María de Mendive y otros destacados maestros a los que, incluso, dedicó algunas de sus crónicas. Su ideario está presente en nuestra gran obra educacional y se concreta en una serie de elementos entre los que se destacan la educación intelectual sólida con carácter científico; la educación moral sobre principios éticos del patriotismo, el latinoamericanismo, la honradez, la sinceridad y la modestia; la igualdad de derechos; la educación estética dirigida al desarrollo en los educandos de expresar y percibir, sentir y disfrutar la belleza; la educación vinculada al trabajo, consideró de gran importancia la educación física. Esto pone de manifiesto que concebía la educación con carácter integral, y manifestó……”la educación de los hombres es la forma futura de los pueblos”. Para Martí la educación que ofrece la escuela, tiene que estar necesariamente de acuerdo a su tiempo y al respecto expresó, “educar es depositar en cada hombre toda la obra humana que le ha antecedido, es hacer a cada hombre resumen del mundo viviente, hasta el día en que vive; es ponerlo a nivel de su tiempo, para que flote sobre él, y no dejarlo debajo de su tiempo, con lo que no podrá salir a flote, es preparar al hombre para la vida”. La obra educacional de la Revolución Cubana ha sido una forma concreta de reconocer la importancia de la teoría y práctica pedagógica de José Martí, desde la rápida y vigorosa campaña de alfabetización, hasta nuestros días, donde nuestros niños y jóvenes crecen en las aulas haciendo realidad el pensamiento martiano que plantea que�

Full Text Available Pneumatophores of Mauritia vinifera Mart. were collected from six month-old plants maintained submerged in fresh water to induce pneumatophore formation. Twenty day-old pneumatophores had a quite prominent root cap. The epidermis was composed of hexagonal cells, tangentially distributed along the cylindric surface of the organ. In transverse section these pneumatophores had a simple epidermis over several layers of sclerified parenchyma, which covered an aerenchyma with large intercellular spaces. The endodermal cells had Casparian strips. The vascular cylinder was polyarch, with a pith and surrounded by a unisseriate pericycle. Anatomically the 4 month-old pneumatophores were similar to the younger ones, except for the absence of the epidermis. The epidermis is replaced by a protective tissue, whose lignified and suberized cells projected themselves outwards, giving it a filamentous aspect. There was no accumulation of starch or tannins in the pneumatophores, except for the presence of statoliths in the root cap. No lenticels were observed in pneumatophores of M. vinifera. The main function of the pneumatophores of M. vinifera is to allow gas exchange, facilitating the supply of oxygen to the submerged root portions.Pneumatóforos de Mauritia vinifera Mart. foram coletados de plantas com seis meses de idade mantidas submersas em água com o objetivo de induzir a formação de pneumatóforos.

This study presents data on allometric relationships of Lychnophora ericoides Mart. (Asteraceae, an extractive resource in the Cerrado region of Brazil. On the Fazenda Água Limpa (15º 45'S, 47º 57'W of the Universidade de Brasilia, 38 individuals of this species were measured in the field, the parts above ground were harvested, separated into components and oven dried. The best regression equations to estimate biomass were geometric and the best fit was between total height and total biomass (r² = 0.923. The economically useful portions, the leaves and branches accounted for approximately 20% of total above ground dry weight, but when used as the dependent variable, the strength of the relationship decreased (r² = 0.694. The relationship between branch diameter and leaf biomass was similar to that between height and leaf dry weight (r² = 0.600. The relation between the number of leaves and their biomass was linear but weak. The development of these equations is the first step towards the implementation of plans for sustainable use of this species.Para o uso sustentável das espécies vegetais nativas o conhecimento da quantidade de biomassa disponível é necessário.

TCRs Used in Cancer Gene Therapy Cross-React with MART-1/Melan-A Tumor Antigens via Distinct Mechanisms

T cells engineered to express TCRs specific for tumor Ags can drive cancer regression. The first TCRs used in cancer gene therapy, DMF4 and DMF5, recognize two structurally distinct peptide epitopes of the melanoma-associated MART-1/Melan-A protein, both presented by the class I MHC protein HLA-A*0201. To help understand the mechanisms of TCR cross-reactivity and provide a foundation for the further development of immunotherapy, we determined the crystallographic structures of DMF4 and DMF5 in complex with both of the MART-1/Melan-A epitopes. The two TCRs use different mechanisms to accommodate the two ligands. Although DMF4 binds the two with a different orientation, altering its position over the peptide/MHC, DMF5 binds them both identically. The simpler mode of cross-reactivity by DMF5 is associated with higher affinity toward both ligands, consistent with the superior functional avidity of DMF5. More generally, the observation of two diverging mechanisms of cross-reactivity with the same Ags and the finding that TCR-binding orientation can be determined by peptide alone extend our understanding of the mechanisms underlying TCR cross-reactivity.

Decoction of roots of the Amazonian palm acai (Euterpe precatoria Mart.) is widely used by Brazilian and Peruvian people as an anti-inflammatory, to heal kidney and liver diseases and against snake bites. In this study, the antioxidant activity of extracts and flavonoids (quercetin, catechin, epicatechin, rutin and astilbin) isolated from roots and leaf stalks of E. precatoria was investigated using {beta}-carotene in TLC plates and DPPH radical scavenging in a spectrophotometric bioassay. All extracts and flavonoids showed activity. Also, the cytotoxic activity of these extracts was evaluated by the brine shrimp (Artemia salina) larvicide bioassay and was lower than that of lapachol, used as control. The presence of flavonoids and sitosterol-3-O-{beta}-D-glucopyranoside in the extracts can justify the use of the plant in traditional medicine. (author)

In Quest of the Antique: The Bazaar, Exchange and Mart and the Democratization of Collecting, 1926-42.

Egginton, Heidi

2017-06-01

The popularization of antique collecting is typically located in the second half of the twentieth century, with the rise of 'retrochic' and the emergence of new markets and online trading websites for anonymously exchanging second-hand goods. Close study of the printed literature connected with the inter-war second-hand trade, however, challenges conventional chronologies in the history of consumer culture, and can provide a new perspective on the role of collecting in British social and cultural life. This article examines the period, after the late 1920s, during which The Bazaar, Exchange and Mart reinvented itself as a forum for antique and decorative art enthusiasts. It argues that, in speaking to and publishing contributions from so-called 'small collectors', this 'Popular Weekly for Collectors and Connoisseurs' helped shape a modern and democratic culture of art appreciation in which ordinary people were actively invited to participate. The private correspondence archive of a Buckinghamshire subscriber who used the Exchange and Mart to sell his collection of 'Egyptian, Greek, and Roman Antiquities' to readers across the country during the 1930s reveals an intimate portrait of the desires, fantasies, and pleasures associated with the popular experience of collecting in pre-war Britain. © The Author [2016].

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.

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.

This study evaluated, in vitro, the antimicrobial activity of the hexane extract (JCHE), methanol extract (JCME), and chloroform fraction (JCCF) of bark from Jacaranda cuspidifolia Mart. (Family Bignoniaceae), a Brazilian medicinal plant, traditionally used as anti-syphilis and anti-gonorrhea treatment. The antimicrobial activity was evaluated using the disc diffusion method followed by the determination of minimum inhibitory concentration (MIC) values. JCHE was not active against the bacteria evaluated. JCME presented antibacterial activity against Streptococcus pyogenes, Staphylococcus aureus, and Neisseria gonorrhoeae with MIC values of 16.3 mg/mL, 9.1 mg/mL, and 25.2 mg/mL, respectively. JCCF was active against Staphylococcus epidermidis, S. aureus, Proteus mirabilis, Serratia marcescens, S. pyogenes, Enterobacter aerogenes, and N. gonorrhoeae with MIC values of 18.3 mg/mL, 9.3 mg/mL, 6.3 mg/mL, 6.1 mg/mL, 9.2 mg/mL, 6.2 mg/mL, and 25.2 mg/mL, respectively. Phytochemical analysis of JCME and JCCF gave positive results for saponins, coumarins, flavonoids, tannins, quinones, alkaloids, triterpenes, and steroids. Verbascoside was isolated and identified as a major peak in JCME and JCCF high-performance liquid chromatography fingerprints and might contribute to the observed antimicrobial activity.

Rural maternity care: can we learn from Wal-Mart?

Science.gov (United States)

van Teijlingen, E R; Pitchforth, E

2010-03-01

In many countries rural maternity care is under threat. Consequently rural pregnant women will have to travel further to attend larger maternity units to receive care and deliver their babies. This trend is not dissimilar from the disappearance of other rural services, such as village shops, banks, post offices and bus services. We use a comparative approach to draw an analogy with large-scale supermarkets, such as the Wal-Mart and Tesco and their effect on the viability of smaller rural shops, depersonalisation of service and the wider community. The closure of a community-maternity unit leads to women attending a different type of hospital with a different approach to maternity care. Thus small community-midwifery units are being replaced, not by a very similar unit that happens to be further away, but by a larger obstetric unit that operates on different models, philosophy and notions of risk. Comparative analysis allows a fresh perspective on the provision of rural maternity services. We argue that previous discussions focusing on medicalisation and change in maternity services can be enhanced by drawing on experience in other sectors and taking a wider societal lens.

Full Text Available Mites associated to Xylopia aromatica (Lam. Mart. (Annonaceae in urban and rural fragments of semidecidual forest. Native plants can shelter a great diversity of mites. Notwithstanding, the conservation of the forest fragments where the plants are located can influence the structure of the mites community. Generally, in homogenous environments the diversity is lower due to the dominance of one or a few species. In this work, we studied the mite community on Xylopia aromatica (Lam. Mart. (Annonaceae in two fragments of semidecidual forest: one on rural and other on urban area. Seven individuals of X. aromatica were monthly sampled from April 2007 to March 2008, in each of these fragments. Descriptive indexes of diversity, dominance and evenness were applied to verify the ecological patterns of the mite community, besides the Student's t-test to compare the abundance between the fragments. We collected 27,365 mites of 37 species belonging to 11 families. Calacarus sp. (Eriophyidae was the most abundant species, representing 73% of the total sampled. The abundance was greater in the urban fragment (67.7%, with the diversity index reaching only 25% of the theoretical maximum expected. Probably, these values might have been influenced by the location of this fragment in the urban area, being more homogeneous and submitted directly to the presence of atmospheric pollution. In this manner, X. aromatica is able to shelter a higher diversity of mites when inserted in preserved ecosystems, since the highest diversity of available resources allows the establishment of richer and most diverse mite community.

Aquatic macrophytes were found to be the potential scavengers of heavy metals from aquatic environment. In this study, several physiological responses of Alternanthera philoxeroides (Mart.) Griseb leaves to elevated concentrations of cadmium (up to 10 mM) were investigated. It was found that A. philoxeroides was able to accumulate cadmium in its leaves. The pigment contents decreased with the increase of the Cd concentrations. The Cd could induce rise of the activity of peroxidase (POD) at lower concentration (<5 mM), however, when the concentration of Cd rose up to 10 mM, the POD activity declined. The changes of superoxide dismutase (SOD) and Catalase (CAT) activities were exactly opposite to that of POD. In the leaves of Cd-treated fronds, the amounts of three polypeptides with apparent molecular weights 80, 39 and 28 kDa, respectively, were became visible in SDS-PAGE. The nature of these polypeptides remains to be determined. - Cd modified a number of physiological processes and particularly chlorophyll degradation

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.)

Full Text Available Combretum leprosum Mart. is a tree species native of the Caatinga, used in the restoration of degraded areas and in folk medicine. Thus, this research aimed to evaluate the germination and vigor of the seeds subjecting them to different pre-germinative treatments, temperatures and substrates. In the first experi- ment, we tested the pre-germinative treatments: mechanical scarification with sandpaper, chemical scarification with H2SO4 for 1, 5, 10 and 20 minutes, immersion in water at 80 oC and imbibition in distilled water for 24 hours, beyond of the control. In the second experiment, after treatment of imbibition in water for 24 hours, the experimental design was completely randomized in a factorial 5 x 4 (five substrates: into paper, sand, coconut fiber, vermiculite and paper towel organized in the form of rolls; and four temperatures: 25, 30, 35 and 20-30 oC. The following parameters were evalueted: seed moisture content, germination, germination speed index, first germination count and seedling length and dry matter weight. The seeds of Combretum leprosum have not coat dormancy. However, pre-germinative treatments of mechanical scarification with sandpaper and imbibi- tion in water for 24 hours allows better expression of seeds vigor. The paper towel and the temperatures of 25, 30 and 20-30 oC provide adequate conditions for evaluating the germination of Combretum leprosum seeds.

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.

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.

Full Text Available Abstract The diet of the stone marten (Martes foina was studied analysing 63 faeces collected from February 1990 to December 1991. The results were expressed as relative percentage of frequency (Fr% and as percentage of mean bulk (Vm%. Mammals, mainly rodents, were the staple in the diet (annual Vm% = 62.9 and reached a maximum peak in winter (Vm% = 79.4. Vegetables were mostly represented by Rosaceae fruits (annual Vm% = 22.3 and were consumed during all year round. Insects, mainly Coleoptera and Orthoptera, were fairly frequently eaten, although their volume was not remarkable (annual Vm% = 4.1. Birds and garbage were scarcely used. The trophic niche breadth of the stone marten, evaluated using the Levin's index (B, varied from 2.49 in winter to 4.8 in summer. In the same study area the diet of the red fox (Vulpes vulpes was studied. The niche overlap between this canid and the stone marten was not extensive (Op = 0.52; Os = 0.51.

Full Text Available Eichhornia crassipes (Mart. Solms is an aquatic invasive weed throughout the tropical and subtropical regions of the world. The plant rarely produces any fruit under natural condition In order to understand the causes of failure of seed set in this plant various aspect of pollen biology were studied. Pollen fertility and pollen viability was assessed using Muntzing� s mixture and in acetic orcein and TTZ, while pollen germination was assessed with different concentrations of sucrose supplemented with boric acid and Ca and Mg salts. The aim of present study was to find out the cause of sexual incompatibility of Eichhornia crassipes (Mart. Solms. In spite of high pollen fertility, pollen viability and pollen germination the species show hardly any fruit set under natural condition. The abnormal pollen germination like curling of pollen tubes, shrinkage of pollen tube tips and bending of pollen tube might be reasons of sexual incompatibility of this species. It is observed that the taxa required comparatively low sucrose concentration (5% for their optimal in vitro pollen germination (54.08%. Boric acid to certain extent also influences the in vitro pollen germination (56.2%. In the present investigation the nature of substrate in association with the effect of Boric acid, CaCO3, MgSO4 on the in vitro pollen germination of Eichhornia crassipes is also worked out. However the tested salts show no significant effect on pollen germination in the present study.

Para a constituição do experimento, as polpas processadas foram armazenadas em pequenas embalagens de politereftalato de etileno (PET transparente e com tampa (mesmo material, com capacidade de 145 mL e refrigeradas a 3 ± 0,2°C e 45% de U.R., durante 5 dias. Foram analisados os seguintes parâmetros: pH, acidez titulável (AT, sólidos solúveis (SS, relação SS/AT, açúcares totais e redutores, pectinas totais e solúveis, teor de antocianinas e fenólicos totais. Ao final, para as polpas de açaí, levando-se em consideração os limites estabelecidos pelo Padrão de Identidade e Qualidade (PIQ, apenas o parâmetro AT apresentou-se fora da instrução normativa. Entretanto, a inexistência de padrões para bacaba inviabilizou tal comparação. Quanto ao teor das pectinas totais, pode-se concluir que ambas as polpas apresentam baixas concentrações desse componente, não sendo indicadas para produção de doces e geleias sem adição de agentes geleificantes. Os teores de compostos fenólicos e de antocianinas, em ambas as polpas, apesar de diminuir com o período de armazenamento refrigerado, apresentam altas concentrações quando em comparação a outros alimentos com apelo funcional.

The person regarded as the link between them is a convert from Islam to Christianity known as Juan Gabriel from Teruel, formerly Ali Alayzar. The arguments in favour of this thesis are presented, first of all, within a historical description of the circumstances and coincidences of the people involved in the production of the two translation projects; secondly, textual evidence is put forward in which correspondences, similarities and differences are highlighted and discussed. We also consider the similarities to the quotations in Juan Andrés’s Confusión o confutación del Alcorán, drawing attention to a circle of other Christian polemicists around Martín García who were all working in various ways with the Arabic Qur’ān.Este artículo se propone estudiar las similitudes entre la traducción latina del Corán encargada por el cardenal Egidio de Viterbo en 1518 y las citas coránicas incluidas en un tratado de polémica titulado Lumbre de fe contra el Alcorán (Valencia, 1521 escrito por un predicador, Fray Martín de Figuerola.

(Combretaceae and of its aqueous (TFAqF, hydroalcoholic (TFHAF, and hexanic (TFHEXF partition fractions have been evaluated. TFEE presented low acute toxicity, antioxidant, and antiulcerogenic activity against ethanol-induced ulcers, which was partially blocked by pretreatment with L-NAME and indomethacin. It reduced the total acidity and raised the pH of gastric secretion. Additionally, TFEE delayed gastric emptying and slightly inhibited the small intestinal transit and also presented a weakly antidiarrheal activity. The antiulcerogenic and antioxidant activity were also detected in TFAqF and TFHAF but not in TFHEXF. The antisecretory and gastroprotective activity of TFEE partially involve the nitric oxide and prostaglandin participation. Nevertheless, TFEE, TFAqF, and TFHAF drastically reduced the mucus layer adhered to the gastric wall of rats treated with ethanol or indomethacin. Complementary studies are required in order to clarify the paradox of the presence of a gastroprotector activity in this plant that, at the same time, reduces the mucus layer adhered to the gastric wall.

El fruto (coyul es apreciado desde la época prehispánica, sin embargo, su consumo ha disminuido frente a otros frutos nativos y así como de los introducidos con mayor aceptación en el mercado. Se realizó un estudio en San Blas, Nayarit, México, en el que se llevó a cabo la caracterización de un agroecosistema típico donde se explotan poblaciones silvestres y cultivadas de coyul de forma tradicional y se resaltó la importancia económica, ecológica y cultural de la especie. Asimismo, se realizó la caracterización fisicoquímica del fruto; la pulpa y la semilla son fuente principalmente de grasas. De esta especie se pueden obtener subproductos tales como aceites comestibles, alimento para ganado, artesanías, entre otros; igualmente se exponen alternativas de uso llevadas a cabo por otras regiones y países que puedan conducir a conservar espacios ecológicos y culturales.

Nitrogen-fixing bacteria and arbuscular mycorrhizal fungi in Piptadenia gonoacantha (Mart. Macbr.

Joel Quintino de Oliveira Júnior

Full Text Available Abstract The family Leguminosae comprises approximately 20,000 species that mostly form symbioses with arbuscular mycorrhizal fungi (AMF and nitrogen-fixing bacteria (NFB. This study is aimed at investigating and confirming the dependence on nodulation and biological nitrogen fixation in the specie Piptadenia gonoacantha (Mart. Macbr., which belongs to the Piptadenia group. Two consecutive experiments were performed in a greenhouse. The experiments were fully randomized with six replicates and a factorial scheme. For the treatments, the two AMF species and three NFB strains were combined to nodulate P. gonoacantha in addition to the control treatments. The results indicate this species’ capacity for nodulation without the AMF; however, the AMF + NFB combinations yielded a considerable gain in P. gonoacantha shoot weight compared with the treatments that only included inoculating with bacteria or AMF. The results also confirm that the treatment effects among the AMF + NFB combinations produced different shoot dry weight/root dry weight ratios. We conclude that AMF is not necessary for nodulation and that this dependence improves species development because plant growth increases upon co-inoculation.

BioMart Central Portal is a first of its kind, community-driven effort to provide unified access to dozens of biological databases spanning genomics, proteomics, model organisms, cancer data, ontology information and more. Anybody can contribute an independently maintained resource to the Central Portal, allowing it to be exposed to and shared with the research community, and linking it with the other resources in the portal. Users can take advantage of the common interface to quickly utilize different sources without learning a new system for each. The system also simplifies cross-database searches that might otherwise require several complicated steps. Several integrated tools streamline common tasks, such as converting between ID formats and retrieving sequences. The combination of a wide variety of databases, an easy-to-use interface, robust programmatic access and the array of tools make Central Portal a one-stop shop for biological data querying. Here, we describe the structure of Central Portal and show example queries to demonstrate its capabilities. Database URL: http://central.biomart.org. PMID:21930507

The use of natural fiber reinforcement thermoplastic polymer is continuously increasing. This fact is manly due to its advantages as low cost, availability, recyclability, low energy demand and then environmental appeal if compared to synthetics fibers. The composites were prepared in different fiber volume ratios (5%, 10% and 20%) mixed with high density polyethylene (HDPE) and heated at 190 deg C. Thermogravimetric analysis and differential scanning calorimetry were used to investigate thermal stability. The composites structure was characterized by Fourier Transform Infrared spectroscopy, X-ray diffractometry. Fiber and residue of piassava (Attalea funifera Mart) chemical composition were determined by Van Soest Method. The results indicate that thermo stability of the composites of HDPE prepared with fiber volume ratios up to 20% is only slightly lowered. (author)

En ese trabajo, el ahora investigador emérito por la Universidad Nacional Autónoma de México y el Sistema Nacional de Investigadores dio cuenta, mediante un meticuloso análisis de fuentes primarias, de la última rebelión que conmovió al México contemporáneo. La investigación de Martínez Assad tuvo muchos méritos, aunque tal vez el mayor de ellos fue el hecho de analizar el movimiento de Saturnino Cedillo en sus aspectos económicos, sociales, políticos e ideológicos. Con la seriedad académica que siempre lo caracteriza, el ahora también Premio Nacional de Ciencias y Artes 2013 examinó los momentos más importantes en la vida del cacique potosino: su incursión en el torbellino revolucionario (1912, su apoyo al Plan de Agua Prieta (1920, su alianza con los gobiernos de Álvaro Obregón (1920-1924 y Plutarco Elías Calles (1924-1928, y su enfrentamiento final con el gobierno de Lázaro Cárdenas (1934-1940. De esta manera, Martínez Assad demostró que Cedillo, al rechazar el socialismo, las huelgas y el ejido, fue expuesto por el Estado cardenista —empeñado en lograr una centralización política y administrativa— como aliado de las compañías petroleras expropiadas el 18 de marzo de 1938 y portavoz del fascismo alemán en México.

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.

Full Text Available 1915 is considered a decisive year in world history. Underneath wartime plundering, eighteenth-century beliefs in social progress and human civilization collapsed, and other political and philosophical credos sprouted, while aesthetic avant-gardes created new forms of artistic and literary expression. That same year, from his exile in Madrid, Martín Luis Guzmán would define the coordinates that would guide his life, while trying to assimilate his recent experiences during the Mexican Revolution and make way as a writer, under the immediate protection of Alfonso Reyes and the far-away but determining one of Pedro Henríquez Ureña. Without abandoning his political vocation and remaining open to new trends, Guzmán drew up his own path, which would lead him alongside his mentors and to the forefront of literature in Spanish.

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.

Silvia Mistral, Constancia de la Mora y Dolores Martí: Relatos y memorias del exilio de 1939

Full Text Available This article discusses the autobiographical accounts of three Republican women from the first generation of Republican exiles, born between 1900 and 1910. The stories are those of Constancia de la Mora, Silvia Mistral and Dolores Martí, all written just following the Spanish Civil War, between 1939 and 1940, although for two of the authors this was the first stage of exile that finally took them on to Mexico. These accounts are examined within the framework of the socio-political context in which the authors lived during the first three decades of the twentieth century. The stories mix the personal and individual with the collective memory. The women harbour very contrary political views - communist and anarchist - within the Republican cause but the fact that they are women with a common plight helps to overcome these differences. The political nature of these narratives also provides a common theme, which forms a collective testimony in the Republican exile period.

Este artículo analiza las narraciones autobiográficas de tres mujeres republicanas, pertenecientes a la primera generación del exilio (nacidas entre 1900 y 1910. Se trata de los relatos de Constancia de la Mora, Silvia Mistral y Dolores Martí.

Aparece en ellos el fruto de una memoria personal e individual, pero insertada en la memoria colectiva de su grupo de referencia, el colectivo exiliado. Las autoras representan tendencias políticas opuestas dentro del bando republicano: el comunismo y el anarquismo, aunque su condición femenina y las circunstancias comunes que atraviesan matizan esas diferencias en sus relatos.

Full Text Available The aim of this article is to analyze from the perspective of ethnoliterature the novel Entre visillos (1958 by Carmen Martín Gaite in relation to the Spain’s social and cultural context in the 1950s. The objective of the work consists of studying the feminine and masculine archetypes that the novel projects, in connection with the gender-related models that National-Catholicism promoted at the time. Many of these models are still prevalent in Spain. For her the novel, as it encapsulated the socio-cultural context of the 1950s, had by itself, as a specific literary product, the power of impinging upon and re-constructing that social reality, especially by producing new archetypes of gender on which to offer alternate models of identity.

El propósito de este artículo es analizar desde una perspectiva etnoliteraria la novela Entre visillos (1958 de Carmen Martín Gaite en relación con el contexto social y cultural de la España de posguerra de los años cincuenta. El objetivo del trabajo consiste en estudiar los arquetipos femeninos y masculinos que se proyectan a través de la novela y su conexión con los modelos de género propuestos por la ideología dominante del nacional-catolicismo, muchos aún vigentes en la sociedad actual. Se trata así de explorar cómo el contexto sociocultural de la época se refleja en la novela y cómo a su vez la propia obra literaria, como producto cultural específico, posee la capacidad de proyectarse sobre esa misma realidad social, contribuyendo así a re-construirla, concretamente a través de la creación de nuevos arquetipos de género que proponen modelos de identidad alternativos.

Interaction of ultrasound with vortices in type-II superconductors

International Nuclear Information System (INIS)

Sonin, E.B.

1996-01-01

The theory of ultrasound in the mixed state of type-II superconductors is suggested which takes into account the Magnus force on vortices, the anti-Magnus force on ions, and diamagnetism of the mixed state. The acoustic Faraday effect (rotation of polarization of the transverse ultrasonic wave propagating along vortices) is linear in the Magnus force in any regime of the flux flow for wavelengths now used in the ultrasound experiments. Therefore, in contrast to previous predictions, the Faraday effect should be looked for only in clean superconductors with a strong Magnus force. copyright 1996 The American Physical Society

On the centenary of the foundation of the Paediatrics Society of Madrid, a tribute is presented to rural medical practice of that time, although there are few documents on the history of rural medicine. The main objective is to describe the context of the rural medical practice in the late 19th and beginning 20th century, while presenting a historical biographical review of Manuel Martínez Saldise, who was medical specialist from Cazalegas (Toledo). He was appointed an Honorary Member by the Paediatrics Society of Madrid in 1927. A search was carried out in repositories of digitized media, web portals of history of medicine, PubMed, IME files of local councils and medical colleges. The family archives were reviewed with the collaboration of his descendants. The hiring of rural doctors was carried out by the municipalities, and the salary largely depended on private practice as well as "retainers". Specialist physicians took part in epidemics, legal medicine, and in hygiene measures. They also had disputes with mayors, chiefs, with colleagues and with protectionism. A summary of the biography and occupational activity of Manuel Martínez Saldise is presented. Rural doctors were subjected to the society of their time, with the issues that arose, denouncing the shortcomings of the local administrations, dedicated efforts to their family and the most disadvantaged.

Amostras de folhas em várias fases de desenvolvimento foram coletadas, fixadas e processadas para estudos em microscopia de luz e eletrônica de transmissão e varredura, segundo técnicas convencionais. Testes histoquímicos foram empregados para determinar a natureza química da secreção. Os NEFs estão distribuídos por todo o limbo, sendo mais concentrados nos terços basal e médio de cada folíolo. Estes nectários são embutidos no mesofilo, apresentam tecido secretor envolvido por uma endoderme e são vascularizados por xilema e floema. A atividade secretora dos NEFs é limitada à fase juvenil da folha. Nas folhas mais velhas, os NEFs tornam-se não funcionais. O tecido secretor dos NEFs é formado a partir da protoderme, enquanto a endoderme tem origem no meristema fundamental. No tecido secretor de nectários funcionais as células apresentam citoplasma denso, núcleo volumoso, mitocôndrias, plastídios com sistema de membranas pouco desenvolvido, gotas de óleo dispersas no citosol, dictiossomos e segmentos de retículo endoplasmático liso.

Full Text Available Este artículo constituye la respuesta del autor al comentario crítico realizado, en esta misma sección, por Luciano Martínez, en la pasada edición. El autor sostiene que la economía social y solidaria como un ámbito en construcción, que alberga a diversas vertientes que intentan avanzar hacia otra economía. Este carácter si bien puede albergar dudas, no debe transformase en un fatalismo inmovilizador, que permite la actualización constante del libre mercado como institución hegemónica. Antes que una utopía a denunciar desde una visión “realista”, se trata de construir una economía que combine mecanismos de mercado regulados socio-políticamente y relaciones de reciprocidad y redistribución. El texto explora, en pos de la argumentación, algunos de los elementos que conforman la economía social y solidaria.This article represents the author's response to critical commentary made in this section in the last edition by Luciano Martinez. The author maintains that the social and solidarity economy is a sphere under construction, in which several strands can be found. All of these approaches aim to move towards a different type of economy. This character as a developing realm can prompt doubts; this, however, should not lead to a paralyzing fatalism which allows the constant updating of the free market as a hegemonic institution. Far from a utopia to be denounced from a “realistic” viewpoint of economy, its concerns the construction of an economy that combines socio-politically regulated market mechanisms as well as relations of reciprocity and redistribution. The text also explores some of the elements that make up the solidarity and social economy.
