    2002-01-01

    STS-112 Mission Specialist 2 Sandra H. Magnus is seen during a prelaunch interview. She answers questions about her inspiration to become an astronaut and her career path. She gives details on the mission's goals, the most significant of which will be the installation of the S-1 truss structure on the International Space Station (ISS). The installation, one in a series of truss extending missions, will be complicated and will require the use of the robotic arm as well as extravehicular activity (EVA) by astronauts. Magnus also describes her function in the performance of transfer operations. Brief descriptions are given of experiments on board the ISS as well as on board the Shuttle.

    1997-01-01

    In 1932 Magnus Hirschfeld, the eminent German sexologist, visited Greece. It was after a long journey that took him round the world, lecturing about the new science he had created. In the Greek capital his unconventional theories concerning an intermediate "third sex" and his ideas about sexual reform became the object of an attack in the local press. Close examination of the debate which followed reveals some interesting points regarding Hirschfeld's approach to publicity and his attempts to foster an emancipation movement for homosexual issues.

    Two wind tunnel techniques for determining part of the aerodynamic information required to describe the dynamic bahavior of various types of vehicles in flight are described. Force and moment measurements are determined with a rotary-balance apparatus in a coning motion and with a Magnus balance in a high-speed spinning motion. Coning motion is pertinent to both aircraft and missiles, and spinning is important for spin stabilized missiles. Basic principles of both techniques are described, and specific examples of each type of apparatus are presented. Typical experimental results are also discussed.

    Hanson, Thomas F.

    1982-01-01

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

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

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

    2011-07-01

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

    Calculating formulae of Magnus force on common projectile bodies (cone-shaped and parabola-shaped) with turbulent layers were built based on Magnus theory. The effects of temperature exponential were considered, and curve-fitting approaches were adopted in the research that could give more exact result data. Both flow layer constants and shape constants are presented in Magnus force formulae, which are useful to evaluate Magnus force in different states.

    Expedition and wildeness medicine is a term that combines rescue medicine, sport medicine as well as more specific branches as polar or high altitude medicine. It is being intensively studied both at the reaserch institutes and on expeditions. Ophtalmologists are concentrated on the reaserch of HARH (High Altitude Retinal Hemorrhage), neurologists on HACE reaserch (High Altitude Cerebral Edema), psychologists are developing tests to decsribe cognitive functions and many physicians are being trained to work in extreme enviroment. The result of all this effort are numerous new findings in pathophysiology and therapy of altitude illness, increased security on expedition and further development of expeditionism.

    2011-11-01

    In this study, we investigate the flow characteristics of rotating spheres in the subcritical Reynolds number (Re) regime by measuring the drag and lift forces on the sphere and the two-dimensional velocity in the wake. The experiment is conducted in a wind tunnel at Re = 0 . 6 ×105 - 2 . 6 ×105 and the spin ratio (ratio of surface velocity to the free-stream velocity) of 0 (no spin) - 0.5. The drag coefficient on a stationary sphere remains nearly constant at around 0.52. However, the magnitude of lift coefficient is nearly zero at Re Magnus effect, depending on the magnitudes of the Reynolds number and spin ratio. The velocity field measured from a particle image velocimetry (PIV) indicates that non-zero lift coefficient on a stationary sphere at Re > 2 . 0 ×105 results from the asymmetry of separation line, whereas the inverse Magnus effect for the rotating sphere results from the differences in the boundary-layer growth and separation along the upper and lower sphere surfaces.

  3. Magnus force in superfluids and superconductors

    Science.gov (United States)

    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-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.

    A combination of multinuclear ultra-wideline solid-state NMR, powder X-ray diffraction (pXRD), X-ray absorption fine structure experiments, and first principles calculations of platinum magnetic shielding tensors has been employed to reveal the previously unknown crystal structure of Magnus' pink salt (MPS), [Pt(NH3)4][PtCl4], study the isomeric Magnus' green salt (MGS), [Pt(NH3)4][PtCl4], and examine their synthetic precursors K2PtCl4 and Pt(NH3)4Cl2·H2O. A simple synthesis of MPS is detailed which produces relatively pure product in good yield. Broad (195)Pt, (14)N, and (35)Cl SSNMR powder patterns have been acquired using the WURST-CPMG and BRAIN-CP/WURST-CPMG pulse sequences. Experimentally measured and theoretically calculated platinum magnetic shielding tensors are shown to be very sensitive to the types and arrangements of coordinating ligands as well as intermolecular Pt-Pt metallophilic interactions. High-resolution (195)Pt NMR spectra of select regions of the broad (195)Pt powder patterns, in conjunction with an array of (14)N and (35)Cl spectra, reveal clear structural differences between all compounds. Rietveld refinements of synchrotron pXRD patterns, guided by first principles geometry optimization calculations, yield the space group, unit cell parameters, and atomic positions of MPS. The crystal structure has P-1 symmetry and resides in a pseudotetragonal unit cell with a distance of >5.5 Å between Pt sites in the square-planar Pt units. The long Pt-Pt distances and nonparallel orientation of Pt square planes prohibit metallophilic interactions within MPS. The combination of ultra-wideline NMR, pXRD, and computational methods offers much promise for future investigation and characterization of Pt-containing systems.

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

    Science.gov (United States)

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

    2016-01-01

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

    The orbital angular momentum of the coherently aligned Cooper pairs in superfluid (3)He-A is transmitted to an object immersed in the condensate. The authors evaluate the quasiparticle-scattering asymmetry experienced by a negative ion; this leads to a measurable, purely quantum-mechanical Magnus force deflecting the ion's trajectory. Close to T(sub c), possible hydrodynamic Magnus effects are smaller by the factor delta sub A/(k sub B)(T sub c).

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

    We present new formalism for description of the neutrino oscillations in matter with varying density. The formalism is based on the Magnus expansion and has a virtue that the unitarity of the S-matrix is maintained in each order of perturbation theory. We show that the Magnus expansion provides better convergence of series: the restoration of unitarity leads to smaller deviations from the exact results especially in the regions of large transition probabilities. Various expansions are obtained depending on a basis of neutrino states and a way one splits the Hamiltonian into the self-commuting and non-commuting parts. In particular, we develop the Magnus expansion for the adiabatic perturbation theory which gives the best approximation. We apply the formalism to the neutrino oscillations in matter of the Earth and show that for the solar oscillation parameters the second order Magnus adiabatic expansion has better than 1% accuracy for all energies and trajectories. For the atmospheric {delta}m{sup 2} and small 1-3 mixing the approximation works well (<3% accuracy for sin{sup 2}{theta}{sub 13}=0.01) outside the resonance region 2.7-8 GeV.

  14. A review of the Magnus effect in aeronautics

    Science.gov (United States)

    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.

    2010-11-01

    Flow characteristics and fluid force on a sphere rotating along with axis perpendicular to mean air flow were investigated using Large Eddy Simulation at two different Reynolds numbers of 10,000 and 200,000. As a result of simulation, opposite flow characteristics around the sphere and displacement of the separation point were visualized depending on the Reynolds number even though the sphere rotates at the same rotation speed according to the Reynolds number. When Reynolds number is 10,000, flow characteristics agree with the flow field explained in the Magnus effect. However sphere rotates at the same rotation speed while increasing Reynolds number to 200,000, separation point moves in opposite direction and wake appears in the different direction. The reason of the negative Magnus force was discussed in terms of the boundary layer transition on the surface.

  16. Magnus expansion and in-medium similarity renormalization group

    Science.gov (United States)

    Morris, T. D.; Parzuchowski, N. M.; Bogner, S. K.

    2015-09-01

    We present an improved variant of the in-medium similarity renormalization group (IM-SRG) based on the Magnus expansion. In the new formulation, one solves flow equations for the anti-Hermitian operator that, upon exponentiation, yields the unitary transformation of the IM-SRG. The resulting flow equations can be solved using a first-order Euler method without any loss of accuracy, resulting in substantial memory savings and modest computational speedups. Since one obtains the unitary transformation directly, the transformation of additional operators beyond the Hamiltonian can be accomplished with little additional cost, in sharp contrast to the standard formulation of the IM-SRG. Ground state calculations of the homogeneous electron gas (HEG) and 16O nucleus are used as test beds to illustrate the efficacy of the Magnus expansion.

Finally, some comments on the allowed regions in the solar neutrino parameter space are addressed.

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

    In homogeneous negative phase velocity media, the Doppler and Cherenkov-Vavilov effects and the refraction and pressure of light are anomalous: they are inverse with respect to the corresponding effects in conventional media. Using the geometrical optics approximation, it is shown that the optical Magnus effect in inhomogeneous negative phase velocity media is also anomalous. The effect is demonstrated by considering a metamaterial consisting of parallel amorphous ferromagnetic microwires in a magnetic field. The metamaterial proves to be a left-handed one in the realistic region of the electromagnetic spectrum. The optical properties of such a left-handed medium can be controlled by the external magnetic field.

    2007-01-01

    When Ernst Haeckel was buried in Jena on February 12th, 1919, some of his supporters and followers were allowed to make speeches. One of them was the sexologist Magnus Hirschfeld, although he had entered the German-Monist-Club only six years after its foundation in 1906.

    We establish a general vector field model to describe the role of transverse momentum currents in optical Magnus effect in a free-space. As an analogous of mechanical Magnus effect, the circularly polarized wavepacket in our model plays the role of the rotating ball. For a certain circularly polarized wavepacket, whether the rotation is clockwise or anticlockwise depends on the polarization state. We demonstrate the existence of a novel optical polarization-dependent rotation effect which is signally different from conventional optical Magnus effect in that light-matter interaction is not required. Further, we reveal the relation between transverse momentum currents and optical Magnus effect. Such a polarization-dependent rotation is unavoidable when the wavepacket possesses transverse momentum currents. The intriguing effect should be able to be observed experimentally even in the propagation direction. These findings provide direct evidence for the optical Magnus effect in the free-space. The physics underl...

    The Magnus moment is a result of an uneven pressure distribution that occurs when an object rotates in a crossflow. Unlike the Magnus force, which is often small for spin-stabilized projectiles, the Magnus moment can have a strong detrimental effect on flight stability. According to one source, most transonic and subsonic flight instabilities are caused by the Magnus moment [Modern Exterior Ballistics, McCoy], and yet simulations often fail to accurately predict the Magnus moment in the subsonic regime. In this study, we present hybrid Reynolds Averaged Navier Stokes (RANS) and Large Eddy Simulation (LES) predictions of the Magnus moment for a spin-stabilized projectile. Velocity, pressure, and Magnus moment predictions are presented for multiple Reynolds numbers and spin rates. We also consider the effect of a sting mount, which is commonly used when conducting flow measurements in a wind tunnel or water channel. Finally, we present the initial designs for a novel Magnetic Resonance Velocimetry (MRV) experiment to measure three-dimensional flow around a spinning projectile. This work was supported by the Department of Defense High Performance Computing Modernization Program (DoD HPCMP).

    Coriandrum sativum L. (Apiaceae) is a well known herb, native to the Mediterranean region, also intensively cultivated in Romania. The essential oil obtained from Coriandri fructus posseses antimicrobial, antioxidant and anxiolytic effects. Many parameters such as genetic and climatic factors or agronomical practices can influence the yield and composition of the volatile fraction. Plant density is an important factor for the microenvironment in coriander field. In order to study the effect of planting density on the yield of the essential oil and its composition, a bifactorial experiment was carried out on coriander plants (Sandra cultivar). The experiment was performed with three plant densities on the row (0, 15 and 20 cm); the distance between plant rows was 12.5, 25 and 50 cm, respectively. So, it resulted nine experimental variants. The essential oils obtained by hydrodistillation from fruits have been characterized using gas chromatography and mass spectroscopy analysis (GC-MS). The highest yield (7.9866 kg/ha) was obtained for the plants spaced at 20 cm in between and 25 cm row spacing. The highest content of monoterpene alcohols (50.96%) was obtained with 25 cm row spacing and plant spaced at 0 cm on the row. The main components in all oils were monoterpene alcohols (40.75% - 50.96%) and monoterpenes (32.43-38.44%). The essential oil of coriander fruits (Sandra cultivar) does not meet the requirements of the European Pharmacopoeia, especially concerning the content in linalool. Nevertheless, the high content in monoterpene alcohols and monoterpenes recommends the use of the essential oil as immunomodulatory, analgesic and antiinflammatory agent in rheumatology and also as an antibacterial and antiviral agent. Consequently, the changes in yield and composition of the essential oil of Sandra coriander should be assesed during several periods of vegetation in order to conclude on its pharmaceutical quality.

    The case of a rotating object traveling through viscous fluid appears in many phenomena like the banana ball and missile movement. In this work, we build a model to predict the trajectory of such rotating objects with near-cylinder geometry. The analytical expression of Magnus force is given and a wind tunnel experiment is carried out, which shows the Magnus force is well proportional to the product of angular velocity and centroid velocity. The trajectory prediction is consistent with the trajectory record experiment of Magnus glider, which implies the validity and robustness of this model.

    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 Magnus is not the exclusive site of action of morphine-induced analgesia in clinical conditions.

  18. Why adductor magnus muscle is large: the function based on muscle morphology in cadavers.

    2014-02-01

    The aim of this study was to examine anatomical properties of the adductor magnus through a detailed classification, and to hypothesize its function and size to gather enough information about morphology. Ten cadaveric specimens of the adductor magnus were used. The muscle was separated into four portios (AM1-AM4) based on the courses of the corresponding perforating arteries, and its volume, muscle length, muscle fiber length and physiological cross-sectional area were assessed. The architectural characteristics of these four portions of the adductor magnus were then classified with the aid of principal component analysis. The results led us into demarcating the most proximal part of the adductor magnus (AM1) from the remaining parts (AM2, AM3, and AM4). Classification of the adductor magnus in terms of architectural characteristics differed from the more traditional anatomical distinction. The AM2, AM3, and AM4, having longer muscle fiber lengths than the AM1, appear to be designed as displacers for moving the thigh through a large range of motion. The AM1 appears instead to be oriented principally toward stabilizing the hip joint. The large mass of the adductor magnus should thus be regarded as a complex of functionally differentiable muscle portions.

    The composite tissue flap of the descending genicular vessels with the adductor magnus tendon is a newly developed, reliable method to repair the Achilles tendon and relevant skin defects. The aim of this study was to evaluate the anatomy of the adductor magnus tendon-descending genicular artery bone flap, and the feasibility and value for the repair of the Achilles tendon and relevant skin defects. There were 34 adult specimens used for the anatomy of this flap. The descending genicular artery originates 10.5 ± 1.6 cm above the adductor tubercle, with a diameter of 1.8 ± 0.6 mm and a length of 1.2 ± 0.5 cm. Its articular branch is distributed in the adductor magnus tendon and the medial condyle of the femur. The saphenous branch has a diameter of 1.1 ± 0.3 mm and is distributed in the skin of the upper medial calf. A total of 16 cases of trauma-induced Achilles tendon damage and calcaneus and skin defects were repaired with the vascularized adductor magnus tendon bone flap, including the reconstruction of Achilles tendon insertion and repair of relevant skin defects. All of the composite tissue flaps were viable, the skin sensation of the flaps was recovered, and all patients walked with a normal gait. Our results suggested that the adductor magnus tendon-descending genicular artery bone flap is an alternative method to repair composite tissue defects of the Achilles tendon.

  4. Asymmetry of the Venus nightside ionosphere: Magnus force effects

    Science.gov (United States)

    Pérez-de-Tejada, H.

    2008-11-01

    A study of the dawn-dusk asymmetry of the Venus nightside ionosphere is conducted by examining the configuration of the ionospheric trans-terminator flow around Venus and also the dawn-ward displacement of the region where most of the ionospheric holes and the electron density plateau profiles are observed (dawn meaning the west in the retrograde rotation of Venus and that corresponds to the trailing side in its orbital motion). The study describes the position of the holes and the density plateau profiles which occur at neighboring locations in a region that is scanned as the trajectory of the Pioneer Venus Orbiter (PVO) sweeps through the nightside hemisphere with increasing orbit number. The holes are interpreted as crossings through plasma channels that extend downstream from the magnetic polar regions of the Venus ionosphere and the plateau profiles represent cases in which the electron density maintains nearly constant values in the upper ionosphere along the PVO trajectory. From a collection of PVO passes in which these profiles were observed it is found that they appear at neighboring positions of the ionospheric holes in a local solar time (LST) map including cases where only a density plateau profile or an ionospheric hole was detected. It is argued that the ionospheric holes and the density plateau profiles have a common origin at the magnetic polar regions where plasma channels are formed and that the density plateau profiles represent crossings through a friction layer that is adjacent to the plasma channels. It is further suggested that the dawn-dusk asymmetry in the position of both features in the nightside ionosphere results from a fluid dynamic force (Magnus force) that is produced by the combined effects of the trans-terminator flow and the rotational motion of the ionosphere that have been inferred from the PVO measurements.

    2010-08-01

    The Magnus force (gyroscopic force) acting on magnetic vortices (Bloch lines) within domain boundaries in weak ferromagnets is discussed. A general formula is derived for the Magnus force in weak ferromagnets. The Magnus force is found to be nonzero for most types of domain boundaries and is determined by the average sublattice magnetization and the constants for the Dzyaloshinsky interaction and the exchange interaction between sublattices. Generalized expressions are obtained for the effective Lagrange and Rayleigh functions in weak ferromagnets taking their vortex structure into account. The question of the vortex mass, which has been found to be on the order of m*˜10-14g/cm in YFeO3, is discussed. The dynamic flexure of domain boundaries when moving vortices are present is analyzed. A formula is derived for the magnetic field dependence of the velocity of a vortex in a motionless domain boundary.

    2005-01-01

    Based on Magnus or Fer expansion for solving linear differential equation and operator semi-group theory, Lie group integration methods for general nonlinear dynamic equation are studied. Approximate schemes of Magnus type of 4th, 6th and 8th order are constructed which involve only 1, 4 and 10 different commutators, and the time-symmetry properties of the schemes are proved. In the meantime, the integration methods based on Fer expansion are presented. Then by connecting the Fer expansion methods with Magnus expansion methods some techniques are given to simplify the construction of Fer expansion methods. Furthermore time-symmetric integrators of Fer type are constructed. These methods belong to the category of geometric integration methods and can preserve many qualitative properties of the original dynamic system.

    Based on the Magnus integrator method established in linear dynamic systems, an efficiently improved modified Magnus integrator method was proposed for the second-order dynamic systems with time-dependent high frequencies. Firstly, the secondorder dynamic system was reformulated as the first-order system and the frame of reference was transfered by introducing new variables so that highly oscillatory behaviour inherits from the entries in the meantime. Then the modified Magnus integrator method based on local linearization was appropriately designed for solving the above new form and some improved also were presented. Finally, numerical examples show that the proposed methods appear to be quite adequate for integration for highly oscillatory dynamic systems including Hamiltonian systems problem with long time and effectiveness

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

    Science.gov (United States)

    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.

Three video cameras were used to record the initial spin, projectile motion, and final spin of the ball. From these recordings the initial velocity, initial spin, final spin, horizontal acceleration, vertical acceleration, x position, and y positions of the ball were extracted. The coefficient of drag was calculated to be CD=0.6104 +/-0.06187 and the Magnus coefficient was calculated to be CM=0.6576+/-0.08767.

    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.

    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.

    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× 104, 2.0 × 105, and 1.14 × 106. 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.

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.

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

    Science.gov (United States)

    Takegoshi, K.; Miyazawa, Norihiro; Sharma, Kshama; Madhu, P. K.

    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.

    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.

    Advanced exploration and development in harsh environments require mastery of basic human survival skill. Expeditions into the lethal climates of Earth's polar regions offer useful lessons for tommorrow's lunar pioneers. In Arctic and Antarctic exploration, 'wintering over' was a crucial milestone. The ability to establish a supply base and survive months of polar cold and darkness made extensive travel and exploration possible. Because of the possibility of near-constant solar illumination, the lunar polar regions, unlike Earth's may offer the most hospitable site for habitation. The World Space Foundation is examining a scenario for establishing a five-person expeditionary team on the lunar north pole for one year. This paper is a status report on a point design addressing site selection, transportation, power, and life support requirements.

    The effects of both the Saffman force and Magnus force on sand saltation are investigated. Turbulent flows in a channel and over a barchans dune are considered with sand particles injected into the flow. The results show that both of the forces increase the height and skipping distance of sand saltation, with the Magnus force giving more significant effect on the height. These forces can also increase the sand settling at the lee side of the barchans dune.

    Full Text Available En 1987 los psicólogos estadounidenses James O. Whittaker y Sandra J. Whittaker publicaron la cuarta edición de su famoso libro Psicología. Este fue uno de los textos de introducción más conocidos y utilizados en América Latina y a través de él muchos miles de estudiantes aprendieron sus primeros conceptos sobre la psicología. Esta edición estaba preparada especialmente para su utilización con los alumnos de habla castellana e introducía numerosos tópicos relacionados a la psicología latinoamericana. Además incluía menciones específicas a algunos psicólogos de la región y sus contribuciones a la psicología. Uno de ellos era José de Jesús Aguirre, psicólogo y sacerdote jesuita y uno de los pioneros de la psicología profesional en el Paraguay. Aguirre aplicó la teoría del filósofo holandés Gerard Heymans y su colaborador el psiquiatra Enno Dirk Wiersma con las modificaciones que unos años más tarde introdujo el psicólogo francés René Le Senne. El propósito de la investigación era el análisis de los rasgos tipológicos característicos en la población paraguaya. Con ello, Aguirre iniciaba el estudio científico de la personalidad en el Paraguay. Este artículo estudia la importancia que corresponde asignar a la investigación de Aguirre como parte del texto introductorio de Whittaker y Whittaker. Se analizan los fundamentos teóricos de la tipología de Heymans-Wiersma-Le Senne y las adaptaciones realizadas por Aguirre, además de su aplicación a una muestra superior a las setecientas personas. Esta provenía de diversos niveles educativos, tanto secundarios como universitarios. En la parte concluyente se analiza la relevancia de Aguirre y su trabajo en el contexto de la psicología paraguaya y latinoamericana.

    Directory of Open Access Journals (Sweden)

    P.J. Koehler

    2013-10-01

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

  6. MPPT of Magnus Wind System with DC Servo Drive for the Cylinders and Boost Converter

    Directory of Open Access Journals (Sweden)

    Maro Jinbo

    2015-01-01

    Full Text Available This paper presents an algorithm MPPT (Maximum Power Point Tracking for a Magnus wind system with a DC servo drive system (DC drive and BLDC motor to rotate the turbine cylinders. The optimal cylinders rotation is the one to deliver the maximum power extracted from the wind tracked by fixed and adaptive step HCC (Hill Climbing Control acting on the servo drive. The proposed wind system consists of a PMSG (Permanent Magnet Synchronous Generator, a three-phase diode rectifier, a DC/DC (boost converter, and a resistive load. Furthermore, the boost converter acts with the fixed step HCC algorithm to track the maximum power operating point. Therefore, the MPPT for a Magnus wind system requires both tracking for the optimal cylinder speed and the optimal generator speed.

  7. [Local GABA-ergic modulation of serotonergic neuron activity in the nucleus raphe magnus].

    Science.gov (United States)

    Iniushkin, A N; Merkulova, N A; Orlova, A O; Iniushkina, E M

    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.

    2015-01-01

    Recurrent dislocation of the patella is a common orthopaedic problem which occurs in about 44% of cases after first-time dislocation. In most cases of first-time patellar dislocation, the medial patellofemoral ligament (MPFL) becomes damaged. Between 2010 and 2012, 33 children and adolescents (39 knees) with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon. The aim of our study is to assess the effectiveness of this surgical procedure. The outcomes were evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination) and radiographically (Caton index, sulcus angle, congruence angle, and patellofemoral angle). Four patients demonstrated redislocation with MPFL graft failure, despite the fact that patellar tracking was found to be normal before the injury, and the patients had not reported any symptoms. Statistically significant improvements in Lysholm and Kujala scales, in patellofemoral and congruence angle, were seen (P magnus tendon in children and adolescents with recurrent patellar dislocation.

  9. The tripartite origins of the tonic neck reflex: Gesell, Gerstmann, and Magnus.

    Science.gov (United States)

    Shevell, Michael

    2009-03-03

    The standard neurologic examination of the newborn and infant includes the elicitation of the tonic neck reflex. Normally present, its persistence is suggestive of neurologic dysfunction and a prognostic marker highly suggestive of an adverse outcome. Working in different fields, with different approaches and largely independently, three leaders of early 20th century neurosciences (Rudolf Magnus, Josef Gerstmann, and Arnold Gesell) elaborated different aspects of this primitive reflex. Magnus provided the first description in an animal model utilizing a meticulously prepared decerebrate cat correctly identifying the reflex's reliance on proprioceptors in the neck and processing in the upper cervical segment. Gerstmann first described its occurrence in the setting of neurologic disease, providing a meticulous written description in an early description of the index case of what would later be eponymously designated Gerstmann-Straussler-Scheinker syndrome. Gesell initially described the reflex's fundamental occurrence in normal young infants, highlighting its adaptive role in early development and its persistence as a hallmark of neurologic pathology.

    BACKGROUND: Morphological studies have confirmed that vestibular nuclei accepts serotoninergic projections from nucleus raphe magnus, nucleus raphes pallidus, etc. But it is still unclear whether there is bi-directional association between vestibular nuclei and nucleus raphe magnus.OBJECTIVE: To observe the characteristics of projective fibers from vestibular nuclei to nucleus raphe magnus using tetramethyl rhodamine (TMR) in rats, so as to provide more sufficient morphological evidence of neural association from vestibular nuclei. DESIGN: An observational experiment. SETTING: Department of Anatomy (K.K. Leung Brain Research Center), the Fourth Military Medical University of Chinese PLA. MATERIALS: Eighteen male SD rats of clean degree, weighing 250-280 g, were provided by the Experimental Animal Center of the Fourth Military Medical University of Chinese PLA. METHODS: The experiments were carried out in the laboratory of Department of Anatomy (K.K. Leung Brain Research Center), the Fourth Military Medical University of Chinese PLA from September 2006 to January 2007. All the rats were anesthetized with intraperitoneal injection of pentobarbital sodium, then according to the coordinates on the rat brain atlas, 0.1 μL TMR (100 g/L) was injected into nucleus raphes magnus via the tip of glass microtubule by means of microinjection. Seven days later, the rats were anesthetized, then perfused and fixed to remove brain, and then frozen coronal brain sections were prepared.The retrogradely labeled neurons in the injected and projected sites were observed under fluorescence microscope. Light filters with evoked wave length of 540-553 nm and emission wave length≥1 580 nm were selected to observe the orange TMR-labeled neurons. All the sections were observed and counted under the fluorescence microscope.MAIN OUTCOME MEASURES: Characteristics and number of retrogradely labeled neurons at different sites of nuclei. RESULTS: Totally 18 SD rats were enrolled, 9 of them were

    Morris, T. D.; Bogner, S. K.

    2014-10-01

    We present a variant of the in-medium similarity renormalization group(IMSRG) based on the Magnus expansion. In this new variant, the unitary transformation of the IMSRG is constructed explicitly, which allows for the transformation of observables quickly and easily. Additionally, the stiffness of equations encountered by the traditional solution of the IMSRG can be alleviated greatly. We present results and comparisons for the 3d electron gas.

  12. 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.

  14. Curveballs in protoplanetary disks - the effect of the Magnus force on planet formation

    CERN Document Server

    Forbes, John C

    2015-01-01

    Spinning planetesimals in a gaseous protoplanetary disk 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 disk model and numerical integrations of the equations of motion for individual grains. We focus in particular on meter-sized boulders traditionally expected to spiral in to the central star in as little as 100 years from 1 A.U. We find that there are plausible scenarios in which this force extends the lifetime of these solids in the disk 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 disk if the size of the dust particles is larger than of order 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 f...

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.

  16. Magnus-induced dynamics of driven skyrmions on a quasi-one-dimensional periodic substrate

    We numerically examine driven skyrmions interacting with a periodic quasi-one-dimensional substrate where the driving force is applied either parallel or perpendicular to the substrate periodicity direction. For perpendicular driving, the particles in a purely overdamped system simply slide along the substrate minima; however, for skyrmions where the Magnus force is relevant, we find that a rich variety of dynamics can arise. In the single skyrmion limit, the skyrmion motion is locked along the driving or longitudinal direction for low drives, while at higher drives a transition occurs to a state in which the skyrmion moves both transverse and longitudinal to the driving direction. Within the longitudinally locked phase we find a pronounced speedup effect that occurs when the Magnus force aligns with the external driving force, while at the transition to transverse and longitudinal motion, the skyrmion velocity drops, producing negative differential conductivity. For collectively interacting skyrmion assemblies, the speedup effect is still present and we observe a number of distinct dynamical phases, including a sliding smectic phase, a disordered or moving liquid phase, a moving hexatic phase, and a moving crystal phase. The transitions between the dynamic phases produce distinct features in the structure of the skyrmion lattice and in the velocity-force curves. We map these different phases as a function of the ratio of the Magnus term to the dissipative term, the substrate strength, the commensurability ratio, and the magnitude of the driving force.

    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.

  18. The complete mitochondrial genome of the sexual oribatid mite Steganacarus magnus: genome rearrangements and loss of tRNAs

    Directory of Open Access Journals (Sweden)

    Cameron Stephen L

    2008-11-01

    Full Text Available Abstract Background Complete mitochondrial (mt genomes and the gene rearrangements therein are increasingly used as molecular markers for investigating phylogenetic relationships, especially for elucidating deep splits. Contributing to the complete mt genomes of arthropods, especially Arachnida, available so far, we provide the first complete mt genome of a sarcoptiform mite species, the sexually reproducing oribatid mite Steganacarus magnus (Acari, Oribatida which was determined by sequencing of long PCR products. Results The mt genome of S. magnus lacks 16 tRNAs, only those for leucine, histidine, proline, tryptophan, glutamine and serine are present. Within those tRNAs only tRNA-His and tRNA-Pro have kept their original position, the others are translocated. Furthermore, the mt genome of S. magnus consists of 13,818 bp and it is composed of 13 protein-coding genes and two genes for the ribosomal RNA subunits that are typically found in metazoan mt genomes. The gene order in S. magnus differs from the hypothetical ancestral chelicerate arrangement as conserved in Limulus polyphemus: instead of nad1-rrnL-rrnS-LNR-nad2 (tRNAs excluded S. magnus is nad2-rrnL-nad1-rrnS-LNR. Phylogenetic analyses of a concatenated amino acid dataset of all mt protein-coding genes of 28 arthropod species suggest a sister-group relationship of sarcoptiform and prostigmatid mites (S. magnus and Leptotrombidium. Conclusion The mt gene arrangement of S. magnus differs from the hypothetical ground plan of arthropods and from that of other mites further contributing to the variety of mt gene arrangements found in Arachnida. The unexpected lack of tRNAs is enigmatic, probably showing that the loss of mt genes is an ongoing evolutionary process. For solving phylogenetic relationships of oribatid mite lineages and their position within Acari further complete mt genomes are needed.

    2016-06-01

    Divergence of the Magnus expansion leads to paradoxes in the spin dynamics of solid-state NMR and in quantum informatics. This review presents results on quasi-equilibrium magnetization in a system of dipole-dipole (DD) coupled spins at times T_2\\ll t \\ll T1ρ in multiple-pulse spin locking ( T_2 is the transverse spin relaxation time and T1ρ is the rotating-frame spin-lattice relaxation time). It is shown how contradictions between the results obtained with the Magnus expansion and experimental data can be removed. Systems of two and three DD coupled spins in multi-pulse spin locking are considered, and the entanglement evolution is investigated using both the Magnus expansion and the exact solution. The critical temperature for an entangled state is also found.

  2. 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.

    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.

    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.

    Full Text Available Objective(s: 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. Materials and Methods: To this end, tail blood flow of male Wistar rats was measured by laser doppler following the induction of hypothermia. Results: 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 effectof L-glutamate was reduced by prior intra NRM administrationof NO synthase inhibitor NG-methyl-L-arginine or NG-nitro-L-argininemethyl ester (L-NAME, 0.1 µl, 100 nM. Conclusion: It is concluded that NO modulates the thermoregulatory response of NRM to hypothermia and may interactwith excitatory amino acids in central skin blood flow regulation.

    Full Text Available Recurrent dislocation of the patella is a common orthopaedic problem which occurs in about 44% of cases after first-time dislocation. In most cases of first-time patellar dislocation, the medial patellofemoral ligament (MPFL becomes damaged. Between 2010 and 2012, 33 children and adolescents (39 knees with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon. The aim of our study is to assess the effectiveness of this surgical procedure. The outcomes were evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination and radiographically (Caton index, sulcus angle, congruence angle, and patellofemoral angle. Four patients demonstrated redislocation with MPFL graft failure, despite the fact that patellar tracking was found to be normal before the injury, and the patients had not reported any symptoms. Statistically significant improvements in Lysholm and Kujala scales, in patellofemoral and congruence angle, were seen (P<0.001. A statistically significant improvement in the peak torque of the quadriceps muscle and flexor was observed for 60°/sec and 180°/sec angular velocities (P=0.01. Our results confirm the efficacy of MPFL reconstruction using the adductor magnus tendon in children and adolescents with recurrent patellar dislocation.

  12. Numerical investigation of the effect of sphere dimples on the drag crisis and the Magnus effect

    Li, Jing; Tsubokura, Makoto; Tsunoda, Masaya

    2015-11-01

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

  13. Effects of the Magnus and Saffman forces on the saltation trajectories of sand grain

    2007-10-01

    Saltating sand grains are the primary component of airborne sand and account for 75% of all sand transport flux. The saltation height and horizontal distance traveled by sand grains are key factors in sand-control engineering. In addition to gravity and aerodynamic drag, the Magnus and Saffman forces also play important roles in saltation. To quantify the magnitudes of these forces in saltation we used high-speed multi-flash photography to observe the movement of saltating sand grains in a wind tunnel; this proved to be an efficient technique for determining the movement and rotational velocities of grains of natural sand with grain sizes ranging from 0.2 to 0.3 mm and shear velocities ( u*) of 0.67, 0.83, and 0.87 m s - 1 . The rotational speed of saltating sand grains varied between 200 and 800 rev s - 1 ; mean clockwise and anticlockwise rotational speeds were nearly identical, and both increased with increasing saltation height. With saltation heights divided into 1 cm intervals, the rotational speeds followed a Lorentzian distribution. Calculations based on a saltation model showed that the maximum increases in saltation height and in horizontal distance due to the Magnus force were 10.2 and 24.9%, respectively. The rate of increase of both parameters increased with increasing lift-off angle. The maximum increases in saltation height and horizontal distance of sand grains caused by the Saffman force were only 4.6% and 3.7%, respectively.

    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.

  15. Psychological effects of polar expeditions.

    Palinkas, Lawrence A; Suedfeld, Peter

    2008-01-12

    Polar expeditions include treks and stays at summer camps or year-round research stations. People on such expeditions generally undergo psychological changes resulting from exposure to long periods of isolation and confinement, and the extreme physical environment. Symptoms include disturbed sleep, impaired cognitive ability, negative affect, and interpersonal tension and conflict. Seasonal occurrence of these symptoms suggests the existence of three overlapping syndromes: the winter-over syndrome, the polar T3 syndrome, and subsyndromal seasonal affective disorder. About 5% of people on expeditions meet DSM-IV or ICD criteria for psychiatric disorders. However, they also experience positive or so-called salutogenic outcomes resulting from successfully coping with stress and enhanced self-sufficiency, improved health, and personal growth. Prevention of pathogenic psychological outcomes is best accomplished by psychological and psychiatric screening procedures to select out unsuitable candidates, and by providing access to psychological support, including telephone counselling. Promotion of salutogenic experiences is best accomplished by screening for suitable personality traits, and training participants in individual coping strategies, group interaction, and team leadership.

  17. Exilio y búsqueda del padre en Fuga en mí menor de Sandra Lorenzano

    Directory of Open Access Journals (Sweden)

    Anamaria González Luna

    2014-06-01

    Full Text Available This paper proposes a literary reading centered on the absence of the father as a narrative and psychological element of Sandra Lorenzano’s novel, Fuga en mí menor. The search for the father as a necessary process to configure one’s identity becomes an interior escape, leading the main character to work out a suspended mourning, which finds expression in art and music. The metaphoric pun in the title itself announces the meaning of the escape as a double movement, musical and interior, and anticipates the structure that revolves around one single theme whose counterpoints are the different voices and linguistic codes used by the author, which put music and photography in the focus. The threads of heteroglossia weave individual and collective memory; the sounds and silences, the lights and shadows, European history during the Second World War and Argentine history during the dictatorship as moments that have forced people into exile. In the novel the classic paradigm of Telemachus takes on the shape of exile with all its meaning of separation and loss, and leads to the discovery of being an orphan as a necessary condition to inherit from the father, that is, inherit the possibility of opening up new meanings to the world, as the only possible way to give meaning to the experience of life, to your own history.

    2007-01-01

    Full Text Available Mycogone perniciosa (Magnus Delacr., which causes wet bubble disease of Agaricus bisporus Lange (Imb, results in a considerable crop loss on mushroom farms in Serbia. The isolation and identification of five isolates of M. perniciosa from diseased fruit bodies of white button mushroom from mushroom units in Serbia, Bosnia and Herzegovina and Holland were made. Morpho-physiological characteristics and inter-relationships of the obtained isolates were studied. Macroscopic and microscopic investigations of different zones between colonies of the isolates of M. perniciosa revealed the phenomenon of the hyphal interference between different isolates. The obtained results suggest that hyphal interference could serve as an additional parameter for a more reliable determination of fungal specifity.

    Brennan, Toni; Hegarty, Peter

    2009-12-01

    This article considers the two major biographies of sexologist Magnus Hirschfeld, MD (1868-1935), an early campaigner for "gay rights" avant la lettre. Like him, his first biographer Charlotte Wolff (1897-1986) was a Jewish doctor who lived and worked in Weimar Republic Berlin and fled Germany when the Nazi regime came to power. When researching Hirschfeld's biography (published in English in 1986) Wolff met a librarian and gay activist, Manfred Herzer, who would eventually be a cofounder of the Gay Museum in Berlin and publish (in German, in 1992) the other major Hirschfeld biography currently available. Using, inter alia, the correspondence between Wolff and Herzer, the article aims to explore and interrogate the boundaries and possibilities of "biography" as a form of "doing history."

  20. Unidirectional Transport of Ferromagnetic Particles in a Viscous LiquidInduced by the Magnus Force

    2016-10-01

    Full Text Available We study the unidirectional motion of spherical ferromagnetic particles suspended in a viscous liquid and subjected to the action of an external periodic force and a non-uniformly rotating magnetic field. In the case when the translational and rotational motions of particles are characterized by small Reynolds numbers, we propose a system of equations that describes their dynamics and that accounts for the influence of the Magnus force. Theoretical and numerical analysis of the steady-state solution of this system of equations is carried out, the average velocity of unidirectional (drift motion of particles is calculated, and the dependence of the average velocity on the characteristics of particles, liquid, external force and magnetic field is studied.

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

    2006-09-01

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

    2015-04-01

    We report details of the observation of the intrinsic Magnus (IM) force acting on negative and positive ions trapped just below a free surface of the A phase of superfluid 3He (3He-A). From the transport measurements of the ions along the surface, we found that the IM force acts on both the negative and positive ions. We also demonstrate that the transport measurements could distinguish whether the surface is composed of a chiral monodomain or multiple chiral domains. For multiple chiral domains, the current of the ions was found to be irreproducible and unstable, which was reasonably explained by the formation of the chiral domain structure and the dynamics of the chiral domain walls. For chiral monodomains, the appearance ratio of chirality emerging upon cooling through the superfluid transition temperature was found to depend on the direction of the external magnetic field, which implies the existence of an unknown coupling between the chirality and the magnetic field.

  3. GYRE: An open-source stellar oscillation code based on a new Magnus Multiple Shooting Scheme

    Townsend, R H D

    2013-01-01

    We present a new oscillation code, GYRE, which solves the stellar pulsation equations (both adiabatic and non-adiabatic) using a novel Magnus Multiple Shooting numerical scheme devised to overcome certain weaknesses of the usual relaxation and shooting schemes appearing in the literature. The code is accurate (up to 6th order in the number of grid points), robust, efficiently makes use of multiple processor cores and/or nodes, and is freely available in source form for use and distribution. We verify the code against analytic solutions and results from other oscillation codes, in all cases finding good agreement. Then, we use the code to explore how the asteroseismic observables of a 1.5 M_sun star change as it evolves through the red-giant bump.

  4. Textual alchemy: the transformation of pseudo-Albertus Magnus's Semita recta into the Mirror of Lights.

    Grund, Peter

    2009-11-01

    This article explores the strategies of and the reasons behind the reworking of pseudo-Albertus Magnus's Semita recta into the Mirror of Lights. I argue that the redactor sought to provide a more comprehensive defence of the legitimacy of alchemy than found in the Semita recta. In the process of doing so, he reshaped the original text so as to present three units that addressed different parts of the alchemical opus: first, theory and justification of alchemy; second, basic information on substances and procedures; and, third, practice. The redactor employed sophisticated textual tools identical to those seen in scholastic texts. These strategies, I argue, constitute part of the redactor's attempt to bring authority and credibility to his project and to alchemy in general. Certainly, much more attention needs to be paid to these experiments of textual alchemy in order to understand the practice of alchemy in the late medieval period.

    For inhomogeneous mediums the optical Magnus effect has been derived. The metamaterials fabricated from amorphous ferromagnet Co-Fe-Cr-B-Si microwires are shown to exhibit a negative refractive index for electromagnetic waves over wide scale of GHz frequencies. Optical properties and optical Magnus effect of such metamaterials are tunable by an external magnetic field. Microwave permeability of glass-coated ferromagnetic amorphous microwire exhibiting a weak negative magnetostriction has been studied. The diameter of the microwire was about 20 μm and the diameter of the metal core was about 12 μm. The microwire was wound to comprise a 7/3 washer-shaped composite sample with the volume fraction of magnetic constituent of about 10%. The permeability of the composite sample was measured in a coaxial line in the frequency range from 0.1 to 10 GHz. The composite was found to exhibit a negative permeability within the frequency range from approximately 0.7 to 1.5 GHz, with the permeability being as low as -0.4. Therefore, microwire-based composites, particularly, crossed arrays of microwires may be employed to develop metamaterials for microwave applications. In the composite, the negative microwave permeability is due to the natural ferromagnetic resonance and the negative microwave permittivity is due to the inherent inductance of the wire. Such metamaterials are advantageous in simple design, isotropic in-plane performance, and possible tunability of performance by external magnetic bias. However, for a feasible metamaterial fabricated from microwire arrays, the wires have to exhibit higher magnitude of the ferromagnetic resonance, higher quality factor, and higher resonance frequency.

    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 hip adductor group, innervated predominantly by the obturator nerve, occupies a large volume of the lower limb. However, case reports of patients with obturator nerve palsy or denervation have described no more than minimal gait disturbance. Those facts are surprising, given the architectural characteristics of the hip adductors. Our aim was to investigate which regions of the adductor magnus are innervated by the obturator nerve and by which sciatic nerve and to consider the clinical implications. Twenty-one lower limbs were examined from 21 formalin-fixed cadavers, 18 males and 3 females. The adductor magnus was dissected and was divided into four parts (AM1-AM4) based on the locations of the perforating arteries and the adductor hiatus. AM1 was supplied solely by the obturator nerve. AM2, AM3, and AM4 received innervation from both the posterior branch of the obturator nerve and the tibial nerve portion of the sciatic nerve in 2 (9.5%), 20 (95.2%), and 6 (28.6%) of the cadavers, respectively. The double innervation in more than 90% of the AM3s is especially noteworthy. Generally, AM1-AM3 corresponds to the adductor part, traditionally characterized as innervated by the obturator nerve, and AM4 corresponds to the hamstrings part, innervated by the sciatic nerve. Here, we showed that the sciatic nerve supplies not only the hamstrings part but also the adductor part. These two nerves spread more widely than has generally been believed, which could have practical implications for the assessment and treatment of motor disability.

    Full Text Available  “The people I wrote about were real, for the most part, from here and there, now and then, but sometimes three real people would be braided together into one made-up person… I cut apart and stitched together events to tailor the story, gave it shape so it had a beginning, middle, and end, because real life stories rarely come to us complete. Emotions, though, can’t be invented, can’t be borrowed. All the emotions my characters feel, good or bad are mine.” (xxiii Although Sandra Cisneros draws on autobiographical elements in The House on Mango Street (1984, her novella does not stand for an autobiography, but it rather represents a collage of events, characters, and places that independently from one another constitute vignettes. These vignettes are not necessarily chronologically related, yet they make up a whole of voices, stories, colors, and movements that once reverberated along Mango Street. Through her (Cisneros’s stories, Esperanza Cordero’s stories, and Esperanza’s neighbors’ stories, Cisneros conveys the Southwestern Latino experience of the big city and the streets, of the barrios that is. Taking my cue from Cisneros’s “The House on Mango Street,” I will try to examine how personal experiences become memories and those memories transcend into stories. Is what comes from experience and memory that makes writing strong, powerful, persuasive, and to a certain extent relatable? Have Cisneros’s memories, reflected in Esperanza’s living experience and language contributed to the Latino’s collective memory of the life in the barrios coupled with racism, poverty and shame? On that note, I shall see how Maurice Halbwachs’s concept of collective memory applies to Cisneros’ story and the Latino experience, where Latinos’ memory is dependent upon the life in the barrio within which the majority were/are situated.

    The morphology and infraciliature of a new marine colepid ciliate, Apocoleps magnus gen. nov., spee. nov., are described based on living observations and silver impregnations. The new genus Apocoleps is characterized by having 8 (vs. 6 in most other related genera) armour tiers, spines at both ends of the cell, 3 adoral organelles and plates with 4 reniform uni-windows. Apocoleps magnus spec. nov. is defined by the following features: body elongated and slightly curved, about 100-120μm×35-45 μm in vivo; anterior tertiary tier plate with four uni-windows, most secondary and main tier plates with four uni-windows, posterior tertiary tier plate with two uni-windows; left plate margin slightly serrated; on average 23 transverse and 22 longitudinal ciliary rows; one terminal contractile vacuole; marine habitat.

  13. 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.

  14. Floquet resonant states and validity of the Floquet-Magnus expansion in the periodically driven Friedrichs models

    Science.gov (United States)

    Mori, Takashi

    2015-02-01

    The Floquet eigenvalue problem is analyzed for periodically driven Friedrichs models on discrete and continuous space. In the high-frequency regime, there exists a Floquet bound state consistent with the Floquet-Magnus expansion in the discrete Friedrichs model, while it is not the case in the continuous model. In the latter case, however, the bound state predicted by the Floquet-Magnus expansion appears as a metastable state whose lifetime diverges in the limit of large frequencies. We obtain the lifetime by evaluating the imaginary part of the quasienergy of the Floquet resonant state. In the low-frequency regime, there is no Floquet bound state and instead the Floquet resonant state with exponentially small imaginary part of the quasienergy appears, which is understood as the quantum tunneling in the energy space.

    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.

    Full Text Available AbstractThe topic of this article is the Norwegian concept of “friluftsliv” (outdoor life, used as a pedagogical tool to support personal growth. While supporting personal growth appears to be a central pedagogical strategy within Anglo-American and British youth expeditions and adventure programming, this does not appear to be case in the Norwegian outdoor tradition. My research question is: Do Norwegian Outdoor Education students experience a learning outcome related to personal growth, and to their abilities as leaders/mentors, during ski expeditions? I have collected data through a three-year period, after three ski expeditions with Outdoor Education students from an outdoor bachelor-programme at Telemark University College.The students have given written answers to questions regarding personal growth in which several informants’ express thoughts about experiences related to “self” and “identity”. They reflect upon experiences related to “mastering” and “performing”, to acceptance of their own strengths and weaknesses, and about developing self-confidence. They also reflect upon learning outcomes related to interpersonal relations and abilities, self-control, communication and caregiving. The informants have experienced, as leaders/mentors, that it is important to be able to, to “read” situations, to make good assessments of the situations, and to make good decisions related to the situations. As a follow up to this, the informants highlight the importance of being aware of each individual in the group, the importance of encouragement, being positive and caregiving. This study has shown that ski expeditions in “a Norwegian tradition” may have a potential when it comes to encouraging reflections related to personal growth and leadership abilities. Hopefully this study can contribute to increased awareness of the pedagogical potential, for personal growth, within the Norwegian concept of

  6. Magnus Expansion Approach to Parametric Oscillator Systems in a Thermal Bath

    Zhu, Beilei; Rexin, Tobias; Mathey, Ludwig

    2016-10-01

    We develop a Magnus formalism for periodically driven systems which provides an expansion both in the driving term and in the inverse driving frequency, applicable to isolated and dissipative systems. We derive explicit formulas for a driving term with a cosine dependence on time, up to fourth order. We apply these to the steady state of a classical parametric oscillator coupled to a thermal bath, which we solve numerically for comparison. Beyond dynamical stabilisation at second order, we find that the higher orders further renormalise the oscillator frequency, and additionally create a weakly renormalised effective temperature. The renormalised oscillator frequency is quantitatively accurate almost up to the parametric instability, as we confirm numerically. Additionally, a cut-off dependent term is generated, which indicates the break down of the hierarchy of time scales of the system, as a precursor to the instability. Finally, we apply this formalism to a parametrically driven chain, as an example for the control of the dispersion of a many-body system.

    For homogeneous NPVM (negative phase--velocity mediums) [V. G. Veselago, Soviet Physics - Uspekhi 10 (1968) 509; T. G. Mackay, A. Lakhtakia, Phys. Rev. E 69 (2004) 026602] anomalous effects such as negative refraction, light pressure, Doppler shift, Cherenkov-Vavilov radiation, Goos-Hanchen effect have been discovered in different frequency ranges. In this presentation the optical circular polarized effect is calculated for inhomogeneous mediums (optical Magnus effect) and it is shown that it is anomalous in NPVM with respect to ``right-handed'' materials. The proposed metamaterials fabricated from glass coated amorphous ferromagnetic Co-Fe-Cr-B-Si microwires are shown to exhibit a negative refractive index for electromagnetic waves over scale of GHz frequencies [A.V. Ivanov, A.N. Shalygin, A.V. Vedyayev, V.A. Ivanov, JETP Letters 85 (2007) 565]. The magnetostatic interaction between microwires has been taken into account. The phase and group velocities in proposed metamaterial have been calculated. The ratio of thereof depends monotonically on the size of the microwires. Optical properties of such metamaterials are tunable by an external magnetic field and mechanical stress.

    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 fundamenta...

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

    Directory of Open Access Journals (Sweden)

    Merab G Tsagareli

    2011-07-01

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

    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.

    The phenomenon of a light topological birefringence in a multimode fiber has been discussed in papers. The physical mechanism of the topological birefringence, as expected earlier is determined by the interaction of the two effects, namely, the topological Berry's phase and the optical Magnus effect. So, for a square distribution of a refractive index in a fiber cross section the near-meridianal local waves propagate along ray trajectories represented by strongly stretched ellipses of an elliptical helix. A plane made by a fiber axis and a major axis of a ray elliptical helix undergoes a rotation into the fiber, and the rotation hand of this plane is defined by a sign of the wave polarization circularity. If a linear polarized light drops into a fiber input its left-hand polarized component will rotate the major axis of the elliptical helix counterclockwise, and the right-hand polarized component rotates clockwise. Since the angular rates of this rotation are slightly different one from another forthcoming the local waves having counter circulation of a polarization should be collapsed in a single linear polarized local wave. However if the local wave trajectory doesn't lie in a plane then it is a space curve.

    In this article, we present an alternative expansion scheme called Floquet-Magnus expansion (FME) used to solve a time-dependent linear differential equation which is a central problem in quantum physics in general and solid-state nuclear magnetic resonance (NMR) in particular. The commonly used methods to treat theoretical problems in solid-state NMR are the average Hamiltonian theory (AHT) and the Floquet theory (FT), which have been successful for designing sophisticated pulse sequences and understanding of different experiments. To the best of our knowledge, this is the first report of the FME scheme in the context of solid state NMR and we compare this approach with other series expansions. We present a modified FME scheme highlighting the importance of the (time-periodic) boundary conditions. This modified scheme greatly simplifies the calculation of higher order terms and shown to be equivalent to the Floquet theory (single or multimode time-dependence) but allows one to derive the effective Hamiltonian in the Hilbert space. Basic applications of the FME scheme are described and compared to previous treatments based on AHT, FT, and static perturbation theory. We discuss also the convergence aspects of the three schemes (AHT, FT, and FME) and present the relevant references.

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

    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.

Zentrale Erkenntnis dieser qualitativen Interviewstudie ist, dass Gendertrainer/-innen neben einer Genderkompetenz über eine Ambivalenzkompetenz verfügen müssen, wollen sie nicht Gefahr laufen, Geschlechterungleichheiten und -stereotypen zu revitalisieren. Überzeugend ist Smykallas Forderung nach der (Re-Politisierung des Feldes genderorientierter Weiterbildung, wofür ihr Rückgriff auf intersektional orientierte Methodiken einen ersten Ansatzpunkt darstellt.Sandra Smykalla’s dissertation, published in 2010, offers detailed insights into the work of gender trainers in the context of the implementation of gender mainstreaming. The main finding of this qualitative interview study is that gender trainers need to have both gender competence and ambivalence competence if they do not want to risk revitalizing gender inequalities and gender stereotypes. Smykalla’s demand for the (re- politicization of the field of gender-oriented training is convincing and her recourse to intersectionally oriented methodologies illustrates a first starting point.

    Polish expedition to Spitsbergen in 1934 was already the second Polish polar expedition to the Arctic. It was scientific-mountaineering in character. 7 persons took part in it: Witold Biernawski (1898-1957)--film-maker and radiotelegraph operator, Stefan Bernadzikiewicz (1907-1939)--expedition leader, Henryk Mogilnicki (1906-1999)--photographer and radiotelegraph operator, Stefan Zbigniew Różycki (1906-1988)--geologist, Stanisław Siedlecki (1912-2002)--meteorological observer, Sylweriusz Bohdan Zagrajski (1892-1940)--triangulator, Antoni Rogal-Zawadzki (1896-1974)--topographer and photogrammetrist. The purpose of this expedition was to collect data in geology and cartography, and to a lesser degree--in glaciology, botany, zoology and meteorology. It lasted from May 20 to September 16, 1934. The time between June 20 - August 28 the group spent on Spitsbergen's Torell Land. The outcome: an area of app. 300 square kilometres of previously undiscovered land was marked by triangular system, covered by photogrammetric photos and surveyed. Geological research covered the land of app. 500 square kilometres and the group collected geological specimens of app. 800 kg in weight. On the basis of their research, two maps (at a scale of 1:50 000 and 1:200 000) were published. The participants collected also botanical and zoological material. Meteorological observations were carried out at the base over Van Keulen fjord throughout the whole expedition. Different objects on Torell Land were named by the expedition, their names referring largely to Poland (Annex I). Approximately 200 photographs and a film were shot by the expedition. Apart from scientific research, the participants published also diaries of the expedition.

    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{sup 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 This study was conducted in order to determine the appropriate treatment for breaking dormancy and the effect of salinity on seed germination of purple coneflower (Echinacea purpurea cv. Magnus, in two separate experiments. In the first experiment, five levels of gibberellic acid (GA3 (0, 250, 500, 1000, and 1500 mg×L−1 with four levels of cold moist stratification period of seeds at 5°C (0, 5, 10 and 15 days were launched. A factorial experiment was conducted in a completely randomized design with four replications. The statistical analysis showed that concentration of 250 mg×L−1 GA3 with 10 days of cold moist chilling significantly increased the percentage of germination of normal seedlings and reduced the mean time of germination. In the second experiment, the seeds were chilled for 10 days at 5°C and half of them treated with 250 mg×L−1 GA3 for 24 hours. The seeds treated with GA3, and those non-treated were subjected to NaCl for salinity stress. The experiment was conducted using five salinity levels (0, 20, 40, 60 and 80 mM NaCl in four replications in a completely randomized design. The results showed that purple coneflower is highly sensitive to salinity in the germination stage. The results also showed that by increasing salinity levels, the percentage of germination and normal seedlings significantly decreased and the mean time to germination increased, compared to the control treatment. But the seeds treated with GA3 showed higher viability and better performance under salinity stress condition.

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

  5. Authigenic albite formation due to water-rock interactions - Case study: Magnus oilfield (UK, Northern North Sea)

    It is the aim of this contribution to test whether organic-inorganic interactions could induce the formation of authigenic albite. This concept and related results are being compared with modelling scenarios which are purely based on inorganic geochemical reactions. In order to unravel the pathway of authigenic albite formation, this paper presents results of a multidisciplinary study from imaging, geochemistry, mineralogy, and hydrogeochemical modelling. The Jurassic reservoir sandstones of the Magnus oilfield (UK, North Sea) were chosen as a test site. Albite occurs with 4-18 wt.% in the Magnus sandstones and its contents vary with depth. However, albite contents increase with increasing K-feldspar contents and decreasing grain size. It occurs in three forms: (1) as lamellae in perthite, (2) as overgrowth on/in corroded feldspar, and, (3) as cloudy replacing albite patches in K-feldspar. The albite overgrowth has the highest chemical purity (100% albite) whilst albite lamellae and replacing albite patches are slightly less pure (containing 1-4% anorthite). Albite appears non-altered, and has a euhedral morphology and dull cathodoluminescence. It commonly co-occurs with corroded K-feldspar grains. The precipitation of diagenetic albite in the Magnus sandstones is attributed to deep burial 80 Ma ago and may have continued until today at temperatures between 90-120 °C. The results of hydrogeochemical modelling offer two possible pathways for the authigenic albite formation: (1) Dissolution of unstable minerals (such as kaolinite and chalcedony) coupled to reduction of ferric iron minerals by products generated during oil generation, migration and degradation; (2) Dissolution of non-end member feldspar, such as K-feldspar with 10% albite, coupled to illite formation can account for trace amounts of albite due to an elevated Na+/K+ activity ratio in the pore water.

    The influence of the initial angular velocity imparted by an electric motor to a spherical solid on its deviation from the vertical in fall is investigated experimentally. Values of the coefficient CM in the formula for the Magnus force at which the trajectories of sphere motion are in agreement with the experimental data are found by calculation. It is established that as the Reynolds number Reω grows the coefficient CM decreases; with Reω˜3·104 CM is 10% of the quantity C{M/0} found by Rubinov and Keller for small Reynolds numbers.

  12. Raphe magnus and reticulospinal actions on primary afferent depolarization of group I muscle afferents in the cat.

    1. In the anaesthetized cat, electrical stimulation of the bulbar reticular formation produced a short latency (2.1 +/- 0.3 ms) positive potential in the cord dorsum. In contrast, stimulation of the nucleus raphe magnus with strengths below 50 microA evoked a slow negative potential with a mean latency of 5.5 +/- 0.6 ms that persisted after sectioning the contralateral pyramid and was abolished by sectioning the ipsilateral dorsolateral funiculus. 2. The field potentials evoked by stimulation of the bulbar reticular formation and of the nucleus raphe magnus had a different intraspinal distribution, suggesting activation of different sets of segmental interneurones. 3. Stimulation of these two supraspinal nuclei produced primary afferent depolarization (PAD) in single Ib fibres and inhibited the PAD elicited by group I volleys in single Ia fibres. The inhibition of the PAD of Ia fibres produced by reticulospinal and raphespinal inputs appears to be exerted on different interneurones along the PAD pathway. 4. It is concluded that, although reticulospinal and raphespinal pathways have similar inhibitory effects on PAD of Ia fibres, and similar excitatory effects on the PAD of Ib fibres, their actions are conveyed by partly independent pathways. This would allow their separate involvement in the control of posture and movement.

  13. Reproductive cycle of Ensis magnus in the Ría de Pontevedra (NW Spain): Spatial variability and fisheries management implications

    Mesoscale differences in the reproductive cycle of the commercial sword razor clam Ensis magnus (Schumacher, 1817) were studied in six shellfish beds in the Ría de Pontevedra (NW Spain) between March 2008 and July 2010. The GCI accurately described the reproductive cycle as indicated by the histological analysis. Both methods showed that the reproductive cycle was similar at different sites and was characterized by a resting stage during summer and early autumn, initiation of gametogenesis in autumn and a period of successive spawning interspersed with gonad recovery during winter and spring. However, a 15-day to one month delay in advanced stages of gametogenesis and maturation was observed between the inner and the outermost site of the ria, as well as an extended spawning period in the outermost area. Lower bottom seawater temperatures at the outermost sites appeared to delay maturation and to prolong the spawning periods, whereas salinity fluctuations at the innermost sites appeared to reduce the length of the cycle. This study provides the first estimation of the size at which E. magnus reaches sexual maturity in the Iberian Peninsula, determined in 79 mm, and it is also the first work in determining the mesoscale variation in gonadal development of any species of the superfamily Solenoidea. The results highlight the importance of carrying out mesoscale studies of the reproductive biology in coastal fisheries resources. Some of the findings of the present study have already been applied in the rotation scheme of the fishery harvesting plan.

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

    ABSTRACT 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.

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

    Science.gov (United States)

    Mananga, Eugene S; Reid, Alicia E

    This paper presents the study of finite pulse widths for the BABA pulse sequence using the Floquet-Magnus expansion (FME) approach. In the FME scheme, the first order F1 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 Λ1 (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 Λ1 (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 Λ1 (0) is ignored. This work uses the Λ1 (t) function to compare the efficiency of the BABA pulse sequence with δ - pulses and the BABA pulse sequence with finite pulses. Calculations of Λ1 (t) and F1 are presented.

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

    Science.gov (United States)

    Bliokh, K Yu; Bliokh, Yu P

    2004-08-01

    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. Appling 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.

    Full Text Available The objective of this work was to investigate possible modes of action of the yeast Cryptococcus magnus in controlling anthracnose (Colletotrichum gloeosporioides on post harvested papaya fruits. 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. A microscopia eletrônica de varredura foi utilizada para avaliar o efeito da levedura sobre inoculações realizadas após a colheita. Os resultados mostraram que C. magnus é capaz de colonizar a superfície de ferimentos nos frutos e vencer a competição por espaço e, provavelmente, por nutrientes. Além disso, C. magnus produz uma matriz de textura característica que afeta a integridade da hifa do patógeno. A competição por espaço e a produção de substâncias que afetam a integridade das hifas estão entre os mais importantes modos de ação desta levedura.

    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.

  11. Martian polar expeditions: problems and solutions.

    Science.gov (United States)

    Cockell, C S

    2001-12-01

    The Martian polar ice caps are regions of substantial scientific interest, being the most dynamic regions of Mars. They are volatile sinks and thus closely linked to Martian climatic conditions. Because of their scale and the precedent set by the past history of polar exploration on Earth, it is likely that an age of polar exploration will emerge on the surface of Mars after the establishment of a capable support structure at lower latitudes. Expeditions might be launched either from a lower latitude base camp or from a human-tended polar base. Based on previously presented expeditionary routes to the Martian poles, in this paper a "spiral in-spiral out" unsupported transpolar assault on the Martian north geographical pole is used as a Reference expedition to propose new types of equipment for the human polar exploration of Mars. Martian polar "ball" tents and "hover" modifications to the Nansen sledge for sledging on CO2-containing water ice substrates under low atmospheric pressures are suggested as elements for the success of these endeavours. Other challenges faced by these expeditions are quantitatively and qualitatively addressed.

    Luis fernando Gómez R

    2012-08-01

    Full Text Available This paper discusses the short story ‘El arroyo de la Llorona’ by female Mexican-American writer Sandra Cisneros. In it the main character, Cleófilas, is subject to social, emotional and economic dependence on her husband, according to the cultural constructs on female identity that are still relevant in Latin-American patriarchal societies. Due to her circumstances of complete marginalisation and domestic violence, Cleófilas chooses to avoid reality, and this avoidance not only costs her mental well-being,but also annuls her will to make changes to her suffocating life. Oppressed by a patriarchal system,Cleófilas develops an unusual interest in the Llorona legend and, through the remembrance of this myth, these two female figures become symbols of resistance and liberation. In the story, the Llorona ceases to be the denigrated woman tradition has always made her out to be, and becomes the image of a contemporary heroine capable of challenging radical patriarchal norms.

  17. John Murray / MABAHISS expedition versus the International Indian Ocean Expedition (IIOE) in retrospect

    Science.gov (United States)

    Aleem, A. A.; Morcos, S. A.

    In addition to its scientific achievements, the John Murray/Mabahiss Expedition was a unique experiment in technology transfer and it pioneered bilateral relations in the field of oceanography, at a time when the Law of the Sea was not even an embryonic concept. The Expedition will be remembered for its profound influence on the development of oceanography in Egypt, and subsequently in several Arab and African countries, as well as for its socio-economic impact in Egypt. The International Indian Ocean Expedition (IIOE) was an elaborate exercise involving both the most sophisticated developments in oceanography of the day and the full complexity of international relations which necessitated the scientific, coordinating and supporting mechanisms of SCOR, IOC and Unesco combined. Each exercise separated by 25 years represented a significant event in the development of oceanography. Each was a natural product of the prevailing state of the art and the international climate. Oceanography had made a quantum jump in technology in the intervening quarter of a century, which had put the cost of deep sea oceanography quite beyond the financial capabilities of many developing countries, an important factor to bear in mind when comparing the impact of the John Murray/Mabahiss Expedition on Egypt with that of the IIOE, on the Indian Ocean countries.

  18. A remarkable new species of the magnus species-group of Cryptocellus (Arachnida, Ricinulei) from Ecuador, with observations on the taxonomy of the New World genera.

    Botero-Trujillo, Ricardo; Valdez-Mondragón, Alejandro

    2016-05-03

    A new ricinuleid species, Cryptocellus chimaera sp. nov., is described based on a male specimen from Northwest Ecuador (Esmeraldas, Reserva Ecológica Mache-Chindul, Estación Biológica Bilsa). This species is unique among all Cryptocellus in having very large longitudinal carapacial translucent areas together with a markedly incrassate femur of leg II. Representing only the second species of the order described from Ecuador, C. chimaera sp. nov. is assigned to the magnus species-group of Cryptocellus Westwood, 1874. Cryptocellus chimaera sp. nov. is remarkable, for its morphology resembles that of Cryptocellus magnus Ewing, 1929, especially with regard to the male copulatory apparatus, although both resemble Pseudocellus Platnick, 1980, due to the presence of diffuse longitudinal carapacial translucent areas. Along with the new species description, a comparative diagnosis and supplementary images are provided for C. magnus. Based on direct observations of some species belonging to the five species-groups of Cryptocellus, we discuss on the occurrence of different morphologies of carapacial translucent areas within the genus. We deem it important to continue the survey of morphological characters, especially within Cryptocellus, in order to increase our understanding of the species-groups and to unravel their relationships.

  19. Equivalence of the Floquet-Magnus and Fer Expansions to Investigate the Dynamics of a Spin System in the Three-Level System.

    Mananga, Eugene Stephane

    2017-08-17

    In this work, we investigated the orders to which the Floquet-Magnus expansion (FME) and Fer expansion (FE) are equivalent or different for the three-level system. Specifically, we performed the third-order calculations of both approaches based on elegant integrations formalism. We present an important close relationship between the Floquet-Magnus and Fer expansions. As the propagator from the FME takes the form of the evolution operator, which removes the constraint of a stroboscopic observation, we appreciated the effects of time-evolution under Hamiltonians with different orders separately. Our work unifies and generalizes existing results of Floquet-Magnus and Fer approaches and delivers illustrations of novel springs that boost previous applications that are based on the classical information. Due to the lack of an unequivocal relationship between the FME and FE, some disagreements between the results produced by these theories will be found, especially in NMR experiments. Our results can find applications in the optimization of NMR spectroscopy, quantum computation, quantum optical control, and coherence in optics and might bear new awareness in fundamental perusals of quantum spin dynamics. This work is an important theoretical and numerical contribution in the general field of spin dynamics.

    2004-01-01

    This paper uses two case studies of U.S. Department of Energy nuclear weapons complex installations to illustrate the integration of expedited site characterization (ESC) and multimedia modeling in the remedial action decision making process. CONCEPTUAL SITE MODELS, MULTIMEDIA MODELS, AND EXPEDITED SITE CHARACTERIZATION: Conceptual site models outline assumptions about contaminates and the spatial/temporal distribution of potential receptors. Multimedia models simulate contaminant transport and fate through multiple environmental media, estimate potential human exposure via specific exposure pathways, and estimate the risk of cancer and non-cancer health outcomes. ESC relies on using monitoring data to quantify the key components of an initial conceptual site model that is modified iteratively using the multimedia model. Two case studies are presented that used the ESC approach: Los Alamos National Laboratory (LANL) and Pantex. LANL released radionuclides, metals, and organic compounds, into canyons surrounding the facility. The Pantex Plant has past waste management operations which included burning chemical wastes in unlined pits, burying wastes in unlined landfills, and discharging plant wastewaters into on-site surface waters. The case studies indicate that using multimedia models with the ESC approach can inform assessors about what, where, and how much site characterization data needs to be collected to reduce the uncertainty associated with risk assessment. Lowering the degree of uncertainty reduces the time and cost associated with assessing potential risk and increases the confidence that decision makers have in the assessments performed.

    In the late nineteenth and early twentieth centuries, a number of European expeditions traveled to the region of Lake Rudolf, now largely in northern Kenya. Although diverse in intent, many of these were undertaken in the interests of furthering colonial territorial claims. In 1900-1901, Major Herbert Henry Austin led a British expedition down to the lake from Khartoum in the north. Of the 62 African, Arab, and European members of this expedition, only 18 (29 %) arrived at its final destination at Lake Baringo in Kenya. Because of a confluence of adverse climatic, social, and political conditions, the expedition ran short of food supplies when it arrived at the northern end of the lake in April 1901. For the next 4 months, the members of the expedition struggled down the west side of the lake and beyond. The greatest mortality (91 %) occurred among the 32 African transport drivers who were the most marginally nourished at the outset of the trip. The lowest mortality among the Africans on the expedition (15 %) occurred among the members of the Tenth Sudanese Rifles Battalion, who had an excellent nutritional status at the start of the expedition. Major Austin himself suffered from severe scurvy with retinal hemorrhages which left him partially blind in his right eye. An analysis of the mortality rates among the groups that participated in this expedition was undertaken. This revealed that poor nutritional status at the start of the trip was predictive of death from starvation.

  8. Role of the red nucleus in suppressing the jaw-opening reflex following stimulation of the raphe magnus nucleus.

    Science.gov (United States)

    Satoh, Yoshihide; Ishizuka, Ken'Ichi; Iwasaki, Shin-ichi

    2014-08-01

    In a previous study, we found that electrical and chemical stimulation of the red nucleus (RN) suppressed the high-threshold afferent-evoked jaw-opening reflex (JOR). It has been reported that the RN receives bilaterally projection fibers from the raphe magnus nucleus (RMg), and that stimulation of the RMg inhibits the tooth pulp-evoked nociceptive JOR. These facts imply that RMg-induced inhibition of the JOR could be mediated via the RN. The present study first examines whether stimulation of the RMg suppresses the high-threshold afferent-evoked JOR. The JOR was evoked by electrical stimulation of the inferior alveolar nerve (IAN), and was recorded as the electromyographic response of the anterior belly of the digastric muscle. The stimulus intensity was 4.0 (high-threshold) times the threshold. Conditioning electrical stimulation of the RMg significantly suppressed the JOR. A further study then examined whether electrically induced lesions of the RN or microinjection of muscimol into the RN affects RMg-induced suppression of the JOR. Electrically induced lesions of the bilateral RN and microinjection of muscimol into the bilateral RN both reduced the RMg-induced suppression of the JOR. These results suggest that RMg-induced suppression of the high-threshold afferent-evoked JOR is mediated by a relay in the RN.

    The 2005 expedition to the Haughton-Mars Project (HMP) research station on Devon Island was part of a NASA-funded project on Space Logistics. A team of nine r&searchers from MIT went to the Canadian Arctic to participate in the annual I-IMP field campaign from July 8 to August 12, 2005. We investigated the applicability of the HMP research station as an analogue for planetary macro- and micro-logistics to the Moon and Mars, and began collecting data for modeling purposes. We also tested new technologies and procedures to enhance the ability of humans and robots to jointly explore remote environments. The expedition had four main objectives. We briefly summarize our key findings in each of these areas. 1. Classes of Supply: First, we wanted to understand what supply items existed at the HMP research station in support of planetary science and exploration research at and around the Haughton Crater. We also wanted to quantify the total amount of imported mass at HMP and compare this with predictions from existing parametric lunar base demand models. 2. Macro-Logistics Transportation Network: Our second objective was to understand the nodes, transportation routes, vehicles, capacities and crew and cargo mass flow rates required to support the HMP logistics network. 3. Agent and Asset Tracking: Since the current inventory management system on ISS relies heavily on barcodes and manual tracking, we wanted to test new automated technologies and procedures such as radio frequency identification RFID) to support exploration logistics. 4. Micro-Logistics (EVA): Finally, we wanted to understand the micro-logistical requirements of conducting both short (Micro-logistics involves the movement of surface vehicles, people and supplies from base to various exploration sites over short distances (<100 km).

  11. Role of opioidergic and GABAergic neurotransmission of the nucleus raphe magnus in the modulation of tonic immobility in guinea pigs.

    Science.gov (United States)

    da Silva, Luis Felipe Souza; Menescal-de-Oliveira, Leda

    2007-04-02

    Tonic immobility (TI) is an inborn defensive behavior characterized by a temporary state of profound and reversible motor inhibition elicited by some forms of physical restraint. Previous results from our laboratory have demonstrated that nucleus raphe magnus (NRM) is also a structure involved in the modulation of TI behavior, as chemical stimulation through carbachol decreases the duration of TI in guinea pigs. In view of the fact that GABAergic and opioidergic circuits participate in the regulation of neuronal activity in the NRM and since these neurotransmitters are also involved in the modulation of TI, the objective of the present study was to evaluate the role of these circuits of the NRM in the modulation of the behavioral TI response. Microinjection of morphine (4.4 nmol/0.2 microl) or bicuculline (0.4 nmol/0.2 microl) into the NRM increased the duration of TI episodes while muscimol (0.5 nmol/0.2 microl) decreased it. The effect of morphine injection into the NRM was blocked by previous microinjection of naloxone (2.7 nmol/0.2 microl). Muscimol at 0.25 nmol did not produce any change in TI duration; however, it blocked the increased response induced by morphine. Our results indicate a facilitatory role of opioidergic neurotransmission in the modulation of the TI response within the NRM, whereas GABAergic activity plays an inhibitory role. In addition, in the present study the modulation of TI in the NRM possibly occurred via an interaction between opioidergic and GABAergic systems, where the opioidergic effect might be due to inhibition of tonically active GABAergic interneurons.

  17. Field Science Ethnography: Methods For Systematic Observation on an Expedition

    Science.gov (United States)

    Clancey, William J.; Clancy, Daniel (Technical Monitor)

    2001-01-01

    The Haughton-Mars expedition is a multidisciplinary project, exploring an impact crater in an extreme environment to determine how people might live and work on Mars. The expedition seeks to understand and field test Mars facilities, crew roles, operations, and computer tools. I combine an ethnographic approach to establish a baseline understanding of how scientists prefer to live and work when relatively unemcumbered, with a participatory design approach of experimenting with procedures and tools in the context of use. This paper focuses on field methods for systematically recording and analyzing the expedition's activities. Systematic photography and time-lapse video are combined with concept mapping to organize and present information. This hybrid approach is generally applicable to the study of modern field expeditions having a dozen or more multidisciplinary participants, spread over a large terrain during multiple field seasons.

    The spiroindimicins are a family of structurally unprecedented alkaloids isolated from the deep-sea-derived marine actinomycete Streptomyces sp. SCSIO 03032. The total syntheses of (±)-spiroindimicins B and C are disclosed, the first of any member of this family. Central to the successful strategy was installing the spirocentre using a mild intramolecular Heck reaction, the assembly of a pentacyclic spirobisindole by Fischer indolization and a late-stage Schöllkopf-Magnus-Barton-Zard (SMBZ) reaction to construct the trisubstituted pyrrole.

    APECS-France, the French national committee of the Association of Polar Early Career Scientists (APECS), was created in 2013 to improve the dissemination of polar sciences towards the general public and school children in particular, through activities developed in French for French schools. During the autumn of 2014, a young polar oceanographer from the University Pierre and Marie Curie, Zoé Koenig, participated in an expedition on board a sailing vessel in the Southern Ocean. APECS-France set up a new education and outreach project called "Zoé en Expé". Using different media, about 800 children, aged 6 to 12, and from 40 schools, were actively involved in the project. Interactions between Zoé and the students occurred before, during, and after the expedition, through a newsletter, a blog updated in real-time during the expedition, webinars (interactive video-conferences), and visits in classrooms when possible. Teachers were given a list of websites dedicated to polar and oceanographic science outreach and activities adapted to the age and level of the students were offered. Different activities were developed around the expedition, depending on teachers' objectives and children affinities. In particular, students were able to relate to the expedition by imagining a day in the life of Chippy, the mascot of the expedition. They were then asked to draw and/or write Chippy's adventures. APECS-France is now planning to edit a children's book using students' drawings as well as photographs taken during the expedition. Older students were also able to follow in real-time sensors released in the Southern Ocean by Zoé, measuring salinity and temperature. Throughout this 3-month project, children were able to study a wide range of topics (oceanography, biology, history, geography…). The expedition and the educational project allowed raising the awareness of children about the fragile and badly known Antarctic environment.

  2. Spatiotemporal Information Extraction from a Historic Expedition Gazetteer

    Full Text Available Historic expeditions are events that are flavored by exploratory, scientific, military or geographic characteristics. Such events are often documented in literature, journey notes or personal diaries. A typical historic expedition involves multiple site visits and their descriptions contain spatiotemporal and attributive contexts. Expeditions involve movements in space that can be represented by triplet features (location, time and description. However, such features are implicit and innate parts of textual documents. Extracting the geospatial information from these documents requires understanding the contextualized entities in the text. To this end, we developed a semi-automated framework that has multiple Information Retrieval and Natural Language Processing components to extract the spatiotemporal information from a two-volume historic expedition gazetteer. Our framework has three basic components, namely, the Text Preprocessor, the Gazetteer Processing Machine and the JAPE (Java Annotation Pattern Engine Transducer. We used the Brazilian Ornithological Gazetteer as an experimental dataset and extracted the spatial and temporal entities from entries that refer to three expeditioners’ site visits (which took place between 1910 and 1926 and mapped the trajectory of each expedition using the extracted information. Finally, one of the mapped trajectories was manually compared with a historical reference map of that expedition to assess the reliability of our framework.

    2001-01-01

    Full Text Available The celebrated fossil locality of Tendaguru (Tanzania, East Africa has been well known for its unique Late Jurassic dinosaur assemblages since the early decades of the 20th century. Recently, within the scope of the German-Tanzanian Tendaguru project, an expedition returned to Tendaguru with the aim of collecting microvertebrates, micro- and macroinvertebrates, plant fossils and new sedimentological and stratigraphical data. Applying a multidisciplinary research approach, the data collected were used to address various controversial issues regarding the Tendaguru Beds. These include their exact age, depositional environments and reconstructions of the palaeoecosystems in which the dinosaurs lived. Field work resulted in a new standard section for the Tendaguru Beds. Preliminary biostratigraphic results, based on ammonites, charophytes and palynomorphs, support a Late Kimmeridgian age for the Nerinea Bed, an early Tithonian age for the Trigonia smeei Bed, and an Early Cretaceous (possibly Valanginian to Hauterivian age for the Trigonia schwarzi Bed. Facies analysis of the Tendaguru Beds indicates environments ranging from storm- and tide-influenced, siliciclastic coastal barrier systems, ooid sand bar complexes and backbarrier tidal flats to sabkha-like coastal plains with brackish lakes and pools. Sedimentological indicators of palaeoclimate and palynological data point to a subtropical to tropical climate with pronounced dry seasons. In concert with sedimentological data, quantitative palaeoecological analysis of macroinvertebrates helped to finetune understanding of environmental factors such as substrate conditions, salinity, sedimentation rate and water depth. Along with abundant microvertebrate remains and fragments of fusain and cuticles, these new data have considerably improved our knowledge of the fauna and flora found in the Tendaguru Beds, and provide a solid basis for developing a better understanding of the Late Jurassic and Early

  4. N Springs expedited response action proposal

    Energy Technology Data Exchange (ETDEWEB)

    1994-01-01

    Since signing the Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement) in 1989, the parties to the agreement have recognized the need to modify the approach to conducting investigations, studies, and cleanup actions at Hanford. To implement this approach, the parties have jointly developed the Hanford Past-Practice Strategy. The strategy defines a non-time-critical expedited response action (ERA) as a response action ``needed to abate a threat to human health or welfare or the environment where sufficient time exists for formal planning prior to initiation of response. In accordance with the past-practice strategy, DOE proposes to conduct an ERA at the N Springs, located in the Hanford 100 N Area, to substantially reduce the strontium-90 transport into the river through the groundwater pathway. The purpose of this ERA proposal is to provide sufficient information to select a preferred alternative at N Springs. The nature of an ERA requires that alternatives developed for the ERA be field ready; therefore, all the technologies proposed for the ERA should be capable of addressing the circumstances at N Springs. A comparison of these alternatives is made based on protectiveness, cost, technical feasibility, and institutional considerations to arrive at a preferred alternative. Following the selection of an alternative, a design phase will be conducted; the design phase will include a detailed look at design parameters, performance specifications, and costs of the selected alternative. Testing will be conducted as required to generate design data.

The introduction of the full paper reviews some relevant papers in the open literature, points out what we believe to be their shortcomings,and then proposes the numerical method mentioned in the title,which we believe is new and better than previous ones and which is explaind in sections 1 and 2. Their core consists of; "Based on Magnus integrator method,the Hills equations were reduced-order and numerically simulated for the rail errors of the satellite formation flying in Hamiltonian system. The second-order dynamic system was reformulated as a system of first-order and the frame of reference was transferred by introducing new state variables so that the canonical characteristic was inherited from the dynamic system. This method was designed for solving the above new first-order system equations, which provide simpler calculations and better accuracy than the traditional fourth-order Runge-Kutta method. "With the presented method,the rail errors problem of two radiuses is studied;the numerical results, presented in Figs 1, and their analysis show preliminarily that it can indieed give good computational accuracy and stability.%基于Magnus积分方法,针对Hamilton系统下卫星编队绕飞轨道误差问题,对二阶Hill's方程进行了降阶变换和数值模拟.通过引进新状态变量将二阶动力学系统表示为一阶动力学系统,从而保留了原二阶动力学系统的典则性质.采用Magnus积分方法求解一阶系统方程,与传统四阶Runge -Kutta方法相比,该方法计算简单,精度高.文中采用该方法分析了两种绕飞半径的轨道误差问题,分析结果表明该方法具有良好的精度和稳定性.

In view of the projectile wing assembly, Magnus effect mechanism was analyzed thoroughly. The results show that twist fin can effectively improve the pressure distribution of wing surface and reduce Magnus effect interference of projectile bodies to wing surface, especially for big attack angle; larger projectile body Magnus force is mainly focused on coccygeal vertebra which is distorted of the vortex symmetry closed to centroid ; Due to projectile interference and geometric profile effect ,empennage lateral force is mainly concentrated on tail.The values of torgue are not much

    Polar expeditions have been associated with changes in the hypothalamic-pituitary-testicular axis consistent with central hypogonadism (i.e., decreased testosterone, luteinising hormone (LH), and follicle stimulating hormone (FSH)). These changes are typically associated with body mass loss. Our aim was to evaluate whether maintenance of body mass during a polar expedition could mitigate against the development of central hypogonadism. Male participants (n = 22) from a 42-day expedition (British Services Antarctic Expedition 2012) volunteered to take part in the study. Body mass, body composition, and strength data were recorded pre- and postexpedition in addition to assessment of serum testosterone, LH, FSH, thyroid hormones, insulin-like growth factor 1 (IGF-1), and trace elements. Energy provision and energy expenditure were assessed at mid- and end-expedition. Daily energy provision was 6335 ± 149 kcal·day(-1). Estimated energy expenditure midexpedition was 5783 ± 1690 kcal·day(-1). Body mass and percentage body fat did not change between pre- and postexpedition. Total testosterone (nmol·L(-1)) (14.0 ± 4.9 vs. 17.3 ± 4.0, p = 0.006), calculated free testosterone (pmol·L(-1)) (288 ± 82 vs. 350 ± 70, p = 0.003), and sex hormone binding globulin (nmol·L(-1)) (33 ± 12 vs. 36 ± 11, p = 0.023) concentrations increased. LH and FSH remained unchanged. Thyroid stimulating hormone (TSH; IU·L(-1)) (2.1 ± 0.8 vs. 4.1 ± 2.1, p polar expeditions. The elevated TSH and free FT3 were consistent with a previously reported "polar T3 syndrome".

    Expedited site characterizations offer substantial savings in time and money when assessing hazardous waste sites. Key to some of these savings is the ability to adapt a sampling program to the ``real-time`` data generated by an expedited site characterization. This paper presents a two-prong approach to supporting adaptive sampling programs: a specialized object-oriented database/geographical information system for data fusion, management and display; and combined Bayesian/geostatistical methods for contamination extent estimation and sample location selection.

  2. 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.

  3. Studying the Effect of Hydro- alcoholic Extract of Valeriana officinalis on the Number and Size of Raphe Magnus Neurons in Mature Rats

    Full Text Available Introduction & Objective: Effective materials from Valerian officinalis L. have too much usage in the pharmacological industry. It is used as a sedative, anticonvulsion, and antidepressant drug. Serotonin has a widespread role in vital function such as sleep, awareness and calmness. In this study we evaluated the effect of hydrochloric extract of valerian on number and size of raphe magnus neurons in adult rat. Materials & Methods:In this experimental study, which was conducted at Yasuj University of Medical Sciences in 2009, forty adult Wistar rats, each 170-250 gr, were divided randomly into four groups (one control group and three experimental groups. The animals were injected daily for one month with doses of 300, 400 and 600 mg/kg of the extract. The control group just received distilled water. After transcardial perfusion, the whole brain was separated, then 10 µm sections of the brain stem were prepared, and hematoxylin and eosin (H&E staining were done. Number and size of raphe magna neurons were observed under light microscope. The gathered data were analyzed by the SPSS software using One-way ANOVA and LSD. Results: The control group did not statistically show significant changes in number of raphe magna neurons. Comparison of the means of long and short diameter neurons showed significant increases in experimental groups with control group (P<0.05. In experimental groups the neuron nucleuses were more euchromatic than the control group. Conclusion: Hydrochloric extract of valerian has no effect on raphe magnus neurons, but it is effective on neurons' size. It can be concluded that the extract increases both neurons activity and serotonin secretion.

Expedition crews relied on several sources of potable water during this period, including water recovered from urine distillate and humidity condensate by the U.S. water processor, water regenerated from humidity condensate by the Russian water recovery system, and Russian ground-supplied potable water. Potable water samples collected during Expeditions 26-30 were returned on Shuttle flights STS-133 (ULF5), STS-134 (ULF6), and STS-135 (ULF7), as well as Soyuz flights 24-27. The chemical quality of the ISS potable water supplies continued to be verified by the Johnson Space Center s Water and Food Analytical Laboratory (WAFAL) via analyses of returned water samples. This paper presents the chemical analysis results for water samples returned from Expeditions 26-30 and discusses their compliance with ISS potable water standards. The presence or absence of dimethylsilanediol (DMSD) is specifically addressed, since DMSD was identified as the primary cause of the temporary rise and fall in total organic carbon of the U.S. product water that occurred in the summer of 2010.

    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.

  19. Geothermal policy development program: expediting the local geothermal permitting process

    Energy Technology Data Exchange (ETDEWEB)

    1981-07-01

    For a number of years, concerns have been raised about the length of time and the complexity involved in obtaining required permits in order to develop the geothermal resource at the Geysers. Perhaps the most important factor is jurisdiction. At the Geysers, all three levels of government - local, state, and federal - exercise significant authority over various aspects of geothermal development. In addition, several agencies within each governmental level play an active role in the permitting process. The present study is concerned primarily with the local permitting process, and the ways in which this process could be expedited. This report begins by looking at the local role in the overall permitting process, and then reviews the findings and conclusions that have been reached in other studies of the problem. This is followed by a case study evaluation of recent permitting experience in the four Geysers-Calistoga KGRA counties, and the report concludes by outlining several approaches to expediting the local permitting process.

    IODP Expedition 339 had two inter-related objectives to recover continuous sedimentary sequences for: (i) studying the Contourite Depositional System formed by the MOW; and (ii) reconstructing North Atlantic climate variability on orbital and suborbital time scales. This Elsevier Virtual Special Issue (VSI) ;Mediterranean Outflow; is comprised of two volumes that are roughly divided along these lines with Marine Geology devoted to (i) and Global and Planetary Change to (ii), although some papers overlap the two themes. The Marine Geology volume contains 9 contributions addressing specific aspects of IODP Expedition 339 related to contourite deposits including sedimentology, seismic interpretation, stratigraphy, physical properties, downhole logging and ichnofacies (Hernández-Molina et al., 2015; Lofi et al., 2015; Ducassou et al., 2015; Alonso et al., 2015; Takashimizu et al., 2016; Nishida, 2015; Dorador and Rodríguez-Tovar, 2015a, 2015b; Kaboth et al., 2015). The Global and Planetary Change volume consists of 18 papers described below, highlighting paleoclimatic results from sites drilled on the SW Iberian Margin and in the Gulf of Cadiz. The two volumes provide a sample of emerging results of Expedition 339 and foretell of the promising research yet to come.

    用黎曼分解和Osher近似方法,计算了旋转和非旋转弹丸三维跨音速绕流场.将计算区域按分块网格和六面体的弹体贴体网格单元划分,为了提高相对流动变量离散中的数值精度,运用了改进的MUSCL格式.选取弹丸旋转频率为0和82赫兹,攻角分别为0°和10°,马赫数0.94,雷诺数为4.0×106条件为算例.获得在中等倾角下,旋转诱导边界层畸变产生了马格努斯效应和不对称涡结构,沿弹底周向压强分布变化和攻角的非线性效应,给出并讨论了弹丸马格努斯力和法向力系数数值结果,计算结果与实验数据吻合良好.%Computations of the three dimensional transonic flowfield about a spinning and nonspinning axisymmetric projectiles are carried out by using Osher's approximate Riemann solver. Multiblock grid techniques are used to obtain a structured hexahedral cells around the projectile. A modified MUSCL scheme is employed to alleviate the inaccuracy in the discretization of the relative variable formulation. In calculation, the cases at spin rates of 0 and 82 Hz for angles of attack from 4 to 10 deg, and at a Mach number of 0.94 and Reynolds number of 4.0× 106 are considered. The Magnus effect is generated on the body by the spininduced boundary layer distortion at moderated incidences, whereas asymmetric vortices tend to invert this effect at upper incidences. The large circumferential pressure variation over the boattail region as well as the nonlinear effect of angle of attack, the total Magnus force and normal force coefficients for the projectile are presented and discussed. Computational solutions show reasonably good agreement with the experimental data.

    从平面角谱理论出发,建立了光束在空气和玻璃界面折射的传输模型.基于这一模型,揭示了光学马格努斯效应中的横向角移现象.对于特定的线偏振和椭圆偏振光束,其折射场重心出现了横向角移,而当入射光束为圆偏振时,横向角移则会消失.在正负折射率界面,光束的横向角移产生了反转现象,这是由于光束存左手材料中发生 了负衍射.超高折射率可明显地减少横向角移,而超低折射率则可显著地增强横向角移.这些发现将为如何调控和增强光学马格努斯效应提供理论依据.%Starting from the plane angular spectrum theory, we establish a transmission model of beanm refraction at the interface between air and glass. Based on this model, we reveal a transverse angular shift in the optical Magnus effect. For a certain linearly and elliptically polarized light beam, the field centroi& of refraction beam exhibits a transverse angular shift. However, the transverse angular shift would vanish when the incident light beam is circularly polarized. At an interface between positive and negative refractive indexes, the transverse angle shift presents a reversed phenomenon whieh is caused by negative diffraction in the |eft-handed materials. Ultra-high refractive index can significantly reduce the transverse angular shift. On the contrary, the ultra-low refractive index can significantly enhanee the transverse angular shift. These findings provide a new method of how to adjust and enhance the optical Magnus effect.

  9. The role of the expedition doctor: lessons from 100 years ago.

    Science.gov (United States)

    Guly, Henry R

    2012-06-01

    This paper explores the role of the doctor on the expeditions of the heroic age of Antarctic exploration. The medical role includes medical screening of prospective expedition members, choosing medical equipment so as to maintain a balance between being able to cope with any eventuality and the cost and weight of equipment and drugs, health screening during an expedition, first aid training for field parties without a doctor, and, obviously, treatment of any injury or disease that occurs. If injury or illness occurs, the presence of a doctor is of great psychological benefit to the expedition. Although medical experience is important, it is probably more important that the doctor is a "team member," playing a full part in the expedition's aims, whether these are scientific, exploration, or reaching some goal. Most of the lessons learned during these expeditions a hundred years ago are just as relevant today.

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

    Science.gov (United States)

    Ma, Fei; Xie, Hong; Dong, Zhi-Qiang; Wang, Yan-Qing; Wu, Gen-Cheng

    2004-07-15

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

  12. Electrolytic lesion of the nucleus raphe magnus reduced the antinociceptive effects of bilateral morphine microinjected into the nucleus cuneiformis in rats.

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

  13. Anti-nociceptive effects of calcitonin gene-related peptide in nucleus raphe magnus of rats: an effect attenuated by naloxone.

    Science.gov (United States)

    Huang, Y; Brodda-Jansen, G; Lundeberg, T; Yu, L C

    2000-08-04

    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.

    As teachers we can live and share a fabulous experience of science and research on the scientific drilling vessels and platforms of IODP-ECORD and JAMSTEC consortiums. ECORD offered us the opportunity to embark on the IODP 359, 360 and 362 expeditions as Education Officers. Our task was to communicate about science with the general public and students from 7 to 25 years-old. In this presentation, we will focus on the 360 expedition, South West Indian Ridge-lower crust and Moho. We explain the three steps of the "teacher at sea" experience from the very first idea to the real pedagogical work during and after the expedition. -Apply, get ready and leave… for two months: From the difficulties you may encounter to the most efficient ways to prepare the pedagogical tasks. -Work, live onboard and get back: We will describe the main activities of the Education officers among the Science party and the way all this can become a highly changing-life experience. -Use data, share and inspire: We will detail some strategies we used to catch the attention of the students. They could participate to "live" science and have a better idea of the job of researcher. Now, we have to inspire others teachers to use our data and pedagogical documents, or to get the opportunity to embark ! What gets out of these crossed experiences is that the quality of the human relationships, and the way the students can get closer to the scientists during the interactions, are the keys to motivate students and give them a new vision of the scientific research.

    Collaborative international marine research programs over the past 60 years have built on the historic tradition of extended national expeditions during the end of the 19th and beginning of the 20th centuries that explored new regions of the ocean and integrated knowledge: the Challenger, Albatross, and Meteor Expeditions. As oceanography matured after WWII, a new style of collaborative program emerged that focused on specific processes or problems rather than general exploration; the International Geophysical Year (IGY, 1957-58) was followed by the International Decade of Ocean Exploration (IDOE, 1970s). The latter set the stage for regular campaign-style oceanography focused on large-scale problems beyond the capability of individuals or small groups. These have become a staple of international oceanography and provide a framework around which oceanographers from around the world can contribute to global ocean discovery regardless of the capabilities of their individual nations. These collaborations have explored everything from processes controlling and associated with the formation of new ocean floor (RIDGE) to the Census of Marine Life. New collaborations have extended the concept of the international campaign to networks of autonomous vehicles (ARGO) in which all data are freely available. Regardless of the immediate discoveries associated with a campaign, much of its influence derives from the free availability of the data. Those research programs that have made digital data freely available have had an enormous follow-on impact as new models (digital and otherwise) are applied to the results. .

  8. Polar poisons: did Botulism doom the Franklin expedition?

    2003-01-01

    In 1845 the Franklin expedition left London with 2 ships and 134 men on board in an attempt to find the route through the Northwest Passage. The ships were built with state-of-the-art technology for their day, but provisioned with supplies from the lowest bidder. After taking on fresh provisions in the Whalefish Islands, off the coast of Greenland, the entire crew was never heard from again. Graves found on remote Beechey Island indicate that three able-bodied seamen died during the first winter. A note written on a ship's log, later found in a cairn, indicate that the expedition's leader, Sir John Franklin, died during the second winter entrapped on the ice, by which time 24 men had also perished. The remaining crew failed in their attempt to walk out of the Arctic by an overland route. In 1981 Owen Beattie, from the University of Alberta, exhumed the remains of the sailors from the three graves on Beechey Island. Elevated lead levels were found in all three sailors. While lead poisoning has been a leading theory of the cause of the crew's deaths, blamed on the crudely tinned provisions the ships carried with them from England, chronic lead exposure may only have weakened the crew, not necessarily killed them. One of three exhumed sailors also had in his intestine the spores of an unspecified Clostridium species. The theory put forth by this article is that Botulism, type E, which is endemic in the Arctic, may have been responsible for their deaths.

    Neurons in the nucleus cuneiformis (CnF), located just ventrolateral to the periaqueductal gray, project to medullary nucleus raphe magnus (NRM), which is a key medullary relay for descending pain modulation and is critically involved in opioid-induced analgesia. Previous studies have shown that antinociceptive response of CnF-microinjected morphine can be modulated by the specific subtypes of glutamatergic receptors within the CnF. In this study, we evaluated the role of NMDA and kainate/AMPA receptors that are widely distributed within the NRM on morphine-induced antinociception elicited from the CnF. Hundred and five male Wistar rats weighing 250-300 g were used. Morphine (10, 20 and 40 microg) and NMDA receptor antagonist, MK-801 (10 microg) or kainate/AMPA receptor antagonist, DNQX (0.5 microg) in 0.5 microl saline were stereotaxically microinjected into the CnF and NRM, respectively. The latency of tail-flick response was measured at set intervals (2, 7, 12, 17, 22, 27 min after microinjection) by using an automated tail-flick analgesiometer. The results showed that morphine microinjection into the CnF dose-dependently causes increase in tail-flick latency (TFL). MK-801 microinjected into the NRM, just 1 min before morphine injection into the CnF, significantly attenuated antinociceptive effects of morphine. On the other hand, DNQX microinjected into the NRM, significantly increased TFL after local application of morphine into the CnF. We suggest that morphine related antinociceptive effect elicited from the CnF is mediated, in part, by NMDA receptor at the level of the NRM whereas kainite/AMPA receptor has a net inhibitory influence at the same pathway.

    Full Text Available Integrated Ocean Drilling Program (IODP Expedition 327 (summer 2010 was designed to resolve the nature of fluid-rock interactions in young, upper volcanic crust on the eastern flank of the Juan de Fuca Ridge. Expedition 327 drilled, cased and cored two new basement holes, conducted hydrogeologic experiments, and installed subseafloorborehole observatories (Circulation Obviation Retrofit Kits, CORKs. These CORKs were intended to allow borehole conditions to recover to a more natural state after the dissipation of disturbances caused by drilling, casing, and other operations; provide a long-term monitoring and sampling presence for determining fluid pressure, temperature, composition,and microbiology; and facilitate the completion of active experiments to resolve crustal hydrogeologic conditions and processes. Expedition 327 was followed (summer2011 by R/V Atlantis Expedition AT18-07, with the remotely-operated vehicle (ROV Jason, to service these CORKs, collect subseafloor pressure data, recover and deploy autonomous fluid and microbial samplers, collect large volumes of borehole fluids, and initiate a cross-hole hydrogeologic experiment using an electromagnetic flowmeter. In addition, Atlantis Expedition AT18-07 refurbished an old CORK that could not be replaced during IODP Expedition 327, completing a critical part of the three-dimensional observation network that is currently being used to monitor a large-scale, directional formation response to long-term fluid flow from the crust.

    2015-04-01

    The International Indian Ocean Expedition (IIOE) was one of the greatest international, interdisciplinary oceanographic research efforts of all time. Planning for the IIOE began in 1959 and the project officially continued through 1965, with forty-six research vessels participating under fourteen different flags. The IIOE motivated an unprecedented number of hydrographic surveys (and repeat surveys) over the course of the expedition covering the entire Indian Ocean basin. And it was an interdisciplinary endeavor that embraced physical oceanography, chemical oceanography, meteorology, marine biology, marine geology and geophysics. The end of 2015 will mark the 50th Anniversary of the completion of the IIOE. SCOR and the IOC are working to stimulate a new phase of coordinated international research focused on the Indian Ocean for a 5-year period beginning in late 2015 and continuing through 2020. The goal is to help to organize ongoing research and stimulate new initiatives in the 2015-2020 time frame as part of a larger expedition. Several International programs that have research ongoing or planned in the Indian Ocean during this time period and many countries are planning cruises in this time frame as well. These programs and national cruises will serve as a core for the new Indian Ocean research focus, which has been dubbed "IIOE-2." The overarching goal of the IIOE-2 is to advance our understanding of interactions between geological, oceanic and atmospheric processes that give rise to the complex physical dynamics of the Indian Ocean region, and to determine how those dynamics affect climate, extreme events, marine biogeochemical cycles, ecosystems and human populations. This understanding is required to predict the impacts of climate change, pollution, and increased fish harvesting on the Indian Ocean and its nations, as well as the influence of the Indian Ocean on other components of the Earth System. New understanding is also fundamental to policy makers for

    Four men, in the company of 16 dogs, skied for five weeks from Gåsefjord to Ellef Ringnes Land, North Canada. The expedition met with considerable unforeseen challenges such as extreme and prolonged cold, unmotivated Greenland dogs, and much pack ice. Psychological reactions were described and measured by a qualitative free text analysis and a test battery including GHQ-30 (General Health Questionnaire) and STAI State (State-Trait Anxiety Inventory) before, during, and after the expedition. Five main themes were found: external influences, relations between men and animals, progress and expectations, interpersonal relations, and thoughts at the end of the expedition. Negative emotional reactions were mostly present at the beginning of the expedition and were related to the environment and the pressure of perceived expectations from the outside world. Frustrations were enhanced by forced inactivity. Perceived essential positive elements were a strong group identity and friendship. The acceptance of dissension was low; the group strived to achieve consensus before decisions were made. The psychometric results showed more stress and anxiety immediately before the expedition than after. These parameters also increased significantly at the beginning of the expedition, then there was a reverse. The level of anxiety was higher in the two leaders. The expedition was concluded in an overall atmosphere of mutual affection, satisfaction, and pride.

    Paran\\'a Ra'anga (the image of Paran\\'a, in Guaran\\'i) is the name of a cultural and scientific expedition that traveled the rivers: R\\'io de la Plata, Paran\\'a and Paraguay, from Buenos Aires to Asunci\\'on, during March 2010. The project brought together some forty scientists and artists from three countries in a slow and enriching cruise, putting in active contact actors from different backgrounds and disciplines -which usually run separately- in the framework of an unusual space-time experience. The project recovers the historical tradition of the trip as an instrument of knowledge and collaboration between the arts and sciences, necessary to build new ways of seeing and understanding the river and its banks. This article reports on the motivations of this project and its projection.

  16. Extraterritorial hunting expeditions to intense fire scars by feral cats

    Feral cats are normally territorial in Australia’s tropical savannahs, and hunt intensively with home-ranges only two to three kilometres across. Here we report that they also undertake expeditions of up to 12.5 km from their home ranges to hunt for short periods over recently burned areas. Cats are especially likely to travel to areas burned at high intensity, probably in response to vulnerability of prey soon after such fires. The movements of journeying cats are highly directed to specific destinations. We argue that the effect of this behaviour is to increase the aggregate impact of cats on vulnerable prey. This has profound implications for conservation, considering the ubiquity of feral cats and global trends of intensified fire regimes.

    传统的社会学边界研究在文学中逐渐受到关注和运用。由于受地理界线、历史文化及种族差异的影响,墨西哥裔美国文学中的边界书写更为突出。以当代墨西哥裔女作家桑德拉·希斯内罗丝的小说《芒果街上的小屋》和《拉拉的褐色披肩》为例,在细读文本的基础上,以格洛丽亚·安扎尔多瓦的边界研究视角为切入点,分析作品所体现的边界概念及其扩展的比喻意义。边界的不利处境反而成为小说中跨民族空间的移民提高自身及改善他们的跨界生活的催化剂,包容不同身份、寻求和谐的“新混血儿意识”帮助他们跨越边界,迈向更广阔的未来。%In the world of letters,there is a growing interest in the traditional sociological border studies. Due to the influences of geographical border,racial differences,history and culture,border writing is es-pecially prominent in Mexican American literature.Taking Mexican American women writer Sandra Cis-neros’s two novels---The House on Mango Street and Caramelo as the analyzing texts,this article a-dopts Gloria Anzaldúa’s border theory to analyze the border consciousness and its extended significance within the two novels.Instead of acting as an obstacle,the plight of living in borderland turns out to be the catalyst for the self-improvement of the Mexican Americans.The new mestiza consciousness inclu-ding a tolerance of ambiguity and a pursuit of harmony helps them to cross the border and create a promis-ing homeland.

    From February to May 2014, NOAA Ship Okeanos Explorer conducted a telepresence-enabled ocean exploration expedition addressing NOAA and National deepwater priorities in the U.S. Gulf of Mexico. The community-driven expedition connected diverse and geographically dispersed audiences including scientists from industry, academia, and government, and educators, students, and the general public. Expedition planning included input from the ocean science and management community, and was executed with more than 70 scientists and students from 14 U.S. states participating from shore in real time. Training the next generation permeated operations: a mapping internship program trained undergraduate and graduate students; an ROV mentorship program trained young engineers to design, build and operate the system; and undergraduate through doctoral students around the country collaborated with expedition scientists via telepresence. Online coverage of the expedition included background materials, daily updates, and mission logs that received more than 100,000 visits by the public. Live video feeds of operations received more than 700,000 views online. Additionally, professional development workshops hosted in multiple locations throughout the spring introduced educators to the Okeanos Explorer Educational Materials Collection and the live expedition, and taught them how to use the website and education resources in their classrooms. Social media furthered the reach of the expedition to new audiences, garnered thousands of new followers and provided another medium for real-time interactions with the general public. Outreach continued through live interactions with museums and aquariums, Exploration Command Center tours, outreach conducted by partners, and media coverage in more than 190 outlets in the U.S. and Europe. Ship tours were conducted when the ship came in to port to engage local scientists, ocean managers, and educators. After the expedition, data and products were

  4. Antinociception induced by intravenous dipyrone (metamizol) upon dorsal horn neurons: involvement of endogenous opioids at the periaqueductal gray matter, the nucleus raphe magnus, and the spinal cord in rats.

    Microinjection of dipyrone (metamizol) into the periaqueductal gray matter (PAG) in rats causes antinociception. This is mediated by endogenous opioidergic circuits located in the PAG itself, in the nucleus raphe magnus and adjacent structures, and in the spinal cord. The clinical relevance of these findings, however, is unclear. Therefore, in the present study, dipyrone was administered intravenously, and the involvement of endogenous opioidergic circuits in the so-induced antinociception was investigated. In rats, responses of dorsal spinal wide-dynamic range neurons to mechanical noxious stimulation of a hindpaw were strongly inhibited by intravenous dipyrone (200 mg/kg). This effect was abolished by microinjection of naloxone (0.5 microg/0.5 microl) into the ventrolateral and lateral PAG or into the nucleus raphe magnus or by direct application of naloxone (50 microg/50 microl) onto the spinal cord surface above the recorded neuron. These results show that dipyrone, a non-opioid analgesic with widespread use in Europe and Latin America, when administered in a clinically relevant fashion causes antinociception by activating endogenous opioidergic circuits along the descending pain control system.

  6. Australian solar eclipse expeditions: the voyage to Cape York in 1871

    Science.gov (United States)

    Lomb, Nick

    2016-04-01

    Techniques such as photography and spectroscopy only became available to study solar eclipses in the 1860s. The first subsequent total eclipse of the Sun to be visible from Australia was one in December 1871 that was visible from far north Queensland. Initiated by the Royal Society of Victoria, astronomers in Melbourne and Sydney cooperated to organise the Australian Eclipse Expedition aboard the steamship Governor Blackall to a suitable observing location. Though on the day of the eclipse clouds prevented viewing, this was an important expedition that was complex to organise and involved dealings with colonial Governments and with relatively large sums of money that Australian scientists had not previously experienced. With a newspaper reporter as part of the expedition along with two photographers the expedition was well recorded and provides a clear insight into the activities of late nineteenth century astronomers and other scientists.

    2010-01-01

    Full Text Available It is well known that throughout the 19th century the Brazilian territory was frequently visited by scientific expeditions conducted by naturalists interested in seeing, studying, and eventually exploring its natural resources. This paper aims at examining another kind of scientific expeditions also frequent from the middle of the century until the beginning of the 20th century but rather neglected in historiography: the solar eclipse expeditions. Through the analysis of the reports produced by the astronomers who traveled to Brazil with the purpose of observing total solar eclipses it is possible to apprehend some patterns in the organization and textual accounts of these expeditions, which may reveal from an unexpected point of view the close interconnections existent between astronomy and society.

    One century ago there was an intense activity in exploring the unknown polar areas. The paper gives an account of 14 expeditions involving 17 physicians. For several years, the official versions were those published by the leaders of the expeditions, the heroes. During the last years, however, the diaries of their companions have been published and provide valuable and rectifying information. Surprisingly, most of the physicians were young and inexperienced and unfit for the extreme strain of the polar areas.

  12. Raman Spectroscopy: an essential tool for future IODP expeditions

    Science.gov (United States)

    Andò, Sergio; Garzanti, Eduardo; Kulhanek, Denise K.

    2016-04-01

    The scientific drilling of oceanic sedimentary sequences plays a fundamental part in provenance studies, paleoclimate recostructions, and source-to-sink investigations (e.g., France-Lanord et al., 2015; Pandey et al., 2015). When studying oceanic deposits, Raman spectroscopy can and does represent an essential flexible tool for the multidisciplinary approach necessary to integrate the insight provided by different disciplines. This new user-friendly technique opens up an innovative avenue to study in real time the composition of detrital mineral grains of any origin, complementing traditional methods of provenance analysis (e.g., sedimentary petrography, heavy minerals; Andò and Garzanti, 2014). Raman spectra can readily reveal the chemistry of foraminiferal tests, nannofossils and other biogenic debris for the study of ecosystem evolution and paleoclimate, or the Ca/Mg ratio in biogenic or terrigenous carbonates for geological or marine biological applications and oil exploration (Borromeo et al., 2015). For the study of pelagic or turbiditic muds, which represent the bulk of the deep-marine sedimentary record, Raman spectroscopy allows us to identify silt-sized grains down to the size of a few microns with the same precision level required in quantitative provenance analysis of sand-sized sediments (Andò et al., 2011). Silt and siltstone also represent a very conspicuous part of the stratigraphic record onshore and usually preserve original mineralogical assemblages better than more permeable interbedded sand and sandstone (Blatt, 1985). Raman spectra can be obtained on sample volumes of only a few cubic microns by a confocal micro-Raman coupled with a standard polarizing light microscope using a 50× objective. The size of this apparatus can be easily placed onboard an IODP vessel to provide crucial information and quickly solve identification problems for the benefit of a wide range of scientists during future expeditions.

    Are you a researcher working in the polar regions of the world or a K-12 science teacher who would like to be part of a field research expedition in the polar regions? Researchers and K-12 science teachers can apply for funding from PolarTREC, a program that pairs researchers and teachers to conduct field science in Antarctica and the Arctic. Our poster presentation will offer details of one such successful researcher/teacher partnership. During the summer of 2016, Science Teacher Stan Skotnicki (Cheektowaga Central Middle School in Buffalo, NY) was teamed up with Assistant Professor Mike Loranty (Colgate University) to study vegetation and ecosystem impacts on permafrost vulnerability. Stan joined Mike and his research team in Northeastern Siberia preparing field sites, collecting data, processing samples, discussing methods, and planning daily activities. In order to raise awareness and broaden the impact of the research being conducted, Stan communicated the science through a series of journals on the PolarTREC website with his students, staff, and members of the community. Additionally, Mike and Stan held a live webinar from Siberia discussing the content of the research, the nature of the fieldwork, and why it was important to travel so far for this information. This expedition allowed Stan to experience working with a field research team for an extended period of time. Mike benefited from having a team member dedicated to learning about and communicating project details that also provided valuable field assistance. Stan gets to bring his hands-on experience back to his classroom in Buffalo and Mike has the opportunity to share his research with a new and different audience, including presenting to students at Cheektowaga Central with the help of his undergraduate students. This model of collaboration provides a number of valuable benefits for both teachers and researchers. While the PolarTREC program provides necessary logistics and funding to conduct these

    2016-05-01

    Sponsors of human drug and biologic products subject to an investigational new drug (IND) application are required to distribute expedited safety reports of serious and unexpected suspected adverse reactions to participating investigators and the FDA to assure the protection of human subjects participating in clinical trials. On September 29, 2010, the FDA issued a final rule amending its regulations governing expedited IND safety reporting requirements that revised the definitions used for reporting and clarified when to submit relevant and useful information to reduce the number of uninformative reports distributed by sponsors. From January 1, 2006, to December 31, 2014, the FDA's Office of Hematology and Oncology Products received an average of 17,686 expedited safety reports per year. An analysis of FDA submissions by commercial sponsors covering this time period suggested a slight increase in the number of expedited safety reports per IND per year after publication of the final rule. An audit of 160 randomly selected expedited safety reports submitted to the FDA's Office of Hematology and Oncology Products in 2015 revealed that only 22 (14%) were informative. The submission of uninformative expedited safety reports by commercial sponsors of INDs continues to be a significant problem that can compromise detection of valid safety signals.

  16. Gender, culture, and astrophysical fieldwork: Elizabeth Campbell and the Lick Observatory-Crocker eclipse expeditions.

    Science.gov (United States)

    Pang, A. S.-K.

    The article is organized as follows. It begins with an overview of women in nineteenth-century American science. It then describes the culture of mountaintop observatories and life on Mount Hamilton. Elizabeth Campbell's unique role in the Crocker-Lick expeditions drew upon her equally unique role in the observatory, and also on the meaning given to women's work in general on the mountain. The bulk of the article focuses on the Campbells and their expeditions to India in 1898, Spain in 1905, and the South Pacific in 1908. The third section compares the Lick Observatory expeditions to those conducted by David Todd of Amherst College. Todd's wife, Mabel Loomis Todd, went into the field several times with her husband, but her place in the field was radically different from Elizabeth Campbell's, a difference that can be ascribed to a combination of local culture and personality. Finally, it compares American expeditions to British expeditions of the period, to see what the absence of British women on expeditions can tell us about the way national scientific styles and cultures affected gender roles in science.

  17. Antibacterial Compounds from Marine Vibrionaceae Isolated on a Global Expedition

    2010-12-01

    Full Text Available On a global research expedition, over 500 bacterial strains inhibitory towards pathogenic bacteria were isolated. Three hundred of the antibacterial strains were assigned to the Vibrionaceae family. The purpose of the present study was to investigate the phylogeny and bioactivity of five Vibrionaceae strains with pronounced antibacterial activity. These were identified as Vibrio coralliilyticus (two strains, V. neptunius (two strains, and Photobacterium halotolerans (one strain on the basis of housekeeping gene sequences. The two related V. coralliilyticus and V. neptunius strains were isolated from distant oceanic regions. Chemotyping by LC-UV/MS underlined genetic relationships by showing highly similar metabolite profiles for each of the two V. coralliilyticus and V. neptunius strains, respectively, but a unique profile for P. halotolerans. Bioassay-guided fractionation identified two known antibiotics as being responsible for the antibacterial activity; andrimid (from V. coralliilyticus and holomycin (from P. halotolerans. Despite the isolation of already known antibiotics, our findings show that marine Vibrionaceae are a resource of antibacterial compounds and may have potential for future natural product discovery.

    The SWEDARP 1997/98 expedition aboard the S.A. Agulhas focused on three study areas along the 6°E meridian: 60°S, the location of the spring ice edge; 56°S, the location of the winter ice edge; and 50.5°S, the Antarctic Polar Front. This intensive study was preceded by a north-south transect through the area measuring surface water properties while under way. An extensive measurement programme included hydrography, tracers, nutrients, organic carbon, trace metals, bacteria, and primary and secondary producers (including production and grazing rates). Analysis of the results from the three study areas does not identify a single factor limiting primary production: water column stability and the optical regime, and probably iron supply contributed to the control of primary production. The study area acted as a sink for atmospheric CO 2 at the time of measurement, while analysis of water column carbon inventories indicated a net CO 2 source integrated over the spring season.

    This classically styled, chilling murder mystery about an expedition under the ice of Jupiter’s ocean moon Europa, backed up by the latest scientific findings on this icy satellite. The science fiction premise explores real possibilities of exploring other bodies in the Solar System, including probing their possible astrobiology. Now that the most recent world war has concluded on Earth, human explorers are returning to exploration, carrying out a full-court press to journey into the alien abyss using tele-operated biorobotics and human-tended submersibles. Nine scientists head out to Jupiter’s icy ocean-moon. But at Europa’s most remote outpost, one by one, the team members who shared the cruise out begin to die under suspicious circumstances. All was well until humans begin diving into Europa’s subsurface ocean. The deaths have all the symptoms of some sort of plague, despite Europa’s seemingly sterile environment. Besides providing thrills, a science section covers the very latest in undersea rob...

    The IODP US implementing organization began a Teacher at Sea Program (TASP) during Expedition 301 to the eastern flank of the Juan de Fuca Ridge. The main scientific objectives of this expedition were to establish borehole observatories as part of a series of multidisciplinary experiments that will help evaluate the hydrogeologic properties of the oceanic crust, including the distribution of fluid pathways within an active hydrothermal system as well as the linkages between fluid circulation, alteration, and microbiological processes. The goals of the U.S. sponsored IODP TASP were to provide the participant with seagoing research experiences, working side-by-side with scientists, using current state-of-the-art approaches to solve scientific problems pertinent to this expedition, and gaining first-hand knowledge of the results of seagoing science. In addition, the participating teacher will use these experiences for translating scientific results into useful teaching resources, such as expedition information materials and help disseminating these resources into classrooms across the country. During IODP Expedition 301, the participating teacher spent 2 months working with shipboard scientists in processing core data and learning the different techniques used for the shipboard laboratory analyses. Several laboratory briefs targeted for middle to high school student audiences were developed during the cruise including the microbiology, chemistry, paleomagnetics, and physical properties laboratories and educational classroom activities are currently being developed. In addition, other laboratory briefs and educational activities for the underway geophysics, core, downhole measurements, and paleontology laboratories are being developed as part of the post-expedition curriculum development initiatives. The teacher also kept a daily journal detailing life at sea experiences as well as all the science and operational developments that took place during the expedition. The

  5. The American transit of Venus expeditions of 1874 and 1882

    Science.gov (United States)

    Dick, Steven J.

    2005-04-01

    When in 1874 and 1882 Venus passed in front of the face of the Sun, most countries with a scientific reputation to keep or to gain made plans to observe the great event. The United States was no exception. The purpose was primarily to measure the solar parallax, and thereby determine the astronomical unit, the distance between the Earth and the Sun. With a 177000 Congressional appropriation for the 1874 event, and 78000 for 1882, the Americans sent out eight well-equipped expeditions for each transit. Under the U.S. Transit of Venus Commission, the responsibility fell to the U. S. Naval Observatory (Dick 2003). Relying heavily on photographic methods, the Americans returned 350 plates in 1874, and 1380 measurable plates in 1882. Simon Newcomb grew skeptical of the results, but in 1894 William Harkness produced a final value of the solar parallax, after adjustments with other constants, of 8.809'', with a probable error of 0.0059'', yielding an Earth-Sun distance of 92797000 miles, with a probable error of 59700 miles. This was a significant improvement over previous estimates. How important were the transit of Venus observations? In the end it was Newcomb who had the final say, for it was his system of astronomical constants that was adopted internationally at a Paris conference in 1896. Ironically, just at this time other methods were proving more accurate than Venus transits. In determining a final value for the solar parallax from all methods, Newcomb gave all photographic observations of the 1874 and 1882 transit a weight of 2, compared to a weight of 40 for Pulkovo Observatory's determination of solar parallax from the constant of aberration. Thus the Venus transit observations played little role in the official value used for the astronomical unit in the 20th century.

Deep-water carbonate mounds up to 2 km wide and 200 m high have been found in typical water depths of 500-1000 m along the continental slope of NW Europe from Morocco to Norway. During the last ten years they have been studied using seismics, shallow coring, high resolution bathymetry, and remotely operated vehicles. The partly-buried Challenger Mound is the first to be completely cored to the mound base, with the aim of answering basic questions such as: What is the sedimentology and structure of the mound? What triggered mound initiation? How does the ecosystem interact with sedimentary fluxes to make the mound grow? How are mound growth phases related to glacial-interglacial cycles? What role do microbial communities and geochemical reaction play in the mound? Analytical work is at an early stage, but already shipboard results reveal some of the mound's secrets. The mound body consists of a 155-m-thick sequence of cold-water coral-bearing Pleistocene sediments (floatstone, rudstone, and wackestone), characterized by 10-meter-scale alternation of light gray and dark green intervals. The carbonate-rich and light-colored layers are partially lithified and feature poor coral preservation or even dissolution. The mound base, virtually identical in the on-mound and off-mound holes, is a sharp Pliocene erosional unconformity, separating coral-bearing sediments from a glauconitic and partly sandy siltstone. No evidence was found for a relation between mound development and hydrocarbon seepage. The results from Challenger Mound will help provide a depositional model with which to interpret deep water carbonate mounds in the geological rock record, and we look forward to future drilling of contrasting carbonate mounds.

  7. Access to the Sea: A Roadmap for Expedition Planning

    The planning process for expeditionary oceanography often spans many years and involves multiple steps, starting from the initial proposal, to logistics planning, cruise execution, post-cruise and scientific reporting. Each year the University-National Oceanographic Laboratory System (UNOLS) Fleet supports a broad spectrum of research operations and their associated logistics support requirements. Operations can vary from single Principle Investigator (PI) cruises to multi-investigators field programs with multi-disciplinary research objectives in locations all over the world. Over the past decade, the process for access to the sea has evolved and continues to be refined through the critical feedback of scientists, marine technicians, and ship operators. Under UNOLS guidance, key guidelines have been identified for all phases of cruise planning; from pre-award to post-expedition to help ensure that the research objectives of programs can be met and that optimal use of our Nation's oceanographic facilities is maintained. An expeditionary roadmap has been created that captures the major milestones essential to executing a research cruise. The roadmap has been introduced during early career scientist workshops and also during the Chief Scientist Training Cruise programs of recent years. It is a useful planning tool not only for early career scientists and new ship users, but also for experienced sea-going scientists. The roadmap will soon be available as a resource tool on the new UNOLS website. This poster will feature the roadmap for expeditionary planning and offer key information about requirements and tips for a successful, safe, research cruise experience. In addition, existing and new requirements associated with custom clearances, export licensing requirements and additional planning considerations also needed when the research requires special facilities such as aircraft or deep submergence vehicles will be discussed.

  8. North Slope (Wahluke Slope) expedited response action cleanup plan

    Energy Technology Data Exchange (ETDEWEB)

    1994-02-01

    The purpose of this action is to mitigate any threat to public health and the environment from hazards on the North Slope and meet the expedited response action (ERA) objective of cleanup to a degree requiring no further action. The ERA may be the final remediation of the 100-I-3 Operable Unit. A No Action record of decision (ROD) may be issued after remediation completion. The US Department of Energy (DOE) currently owns or administers approximately 140 mi{sup 2} (about 90,000 acres) of land north and east of the Columbia River (referred to as the North Slope) that is part of the Hanford Site. The North Slope, also commonly known as the Wahluke Slope, was not used for plutonium production or support facilities; it was used for military air defense of the Hanford Site and vicinity. The North Slope contained seven antiaircraft gun emplacements and three Nike-Ajax missile positions. These military positions were vacated in 1960--1961 as the defense requirements at Hanford changed. They were demolished in 1974. Prior to government control in 1943, the North Slope was homesteaded. Since the initiation of this ERA in the summer of 1992, DOE signed the modified Hanford Federal Agreement and Consent Order (Tri-Party Agreement) with the Washington Department of Ecology (Ecology) and the US Environmental Protection Agency (EPA), in which a milestone was set to complete remediation activities and a draft closeout report by October 1994. Remediation activities will make the North Slope area available for future non-DOE uses. Thirty-nine sites have undergone limited characterization to determine if significant environmental hazards exist. This plan documents the results of that characterization and evaluates the potential remediation alternatives.

  9. Revisiting J.M. Gilliss' astronomical expedition to Chile in 1849‒1852

    Between 1849 and 1852 the U.S. astronomer J.M. Gilliss led an expedition to Santiago, Chile, aimed at improving the accepted value for the solar parallax. Although this particular research project was not a success, the astronomers did make other useful astronomical contributions, and the expedition was the catalyst that led directly to the founding of the Chilean National Observatory. Meanwhile, Gilliss later went on to achieve further prominence as Superintendent of the U.S. Naval Observatory in Washington, D.C. The results of the Chilean expedition were published by Gilliss in a six-volume work titled The U.S. Naval Astronomical Expedition to the Southern Hemisphere during the Years 1849-50-51-52 that was issued over a 40-year period. In Volume I (published in 1855) Gilliss presented a 'warts-and-all' account of Chile, its politics and its people, which at the time—and subsequently—created considerable controversy. In this paper, after briefly reviewing Gilliss' Southern Hemisphere expedition we focus on the extensive non-astronomical narrative that Gilliss presents in this first volume.

  10. Expedition Memory: Towards Agent-based Web Services for Creating and Using Mars Exploration Data.

    2005-01-01

    Explorers ranging over kilometers of rugged, sometimes "feature-less" terrain for over a year could be overwhelmed by tracking and sharing what they have done and learned. An automated system based on the existing Mobile Agents design [ I ] and Mars Exploration Rover experience [2], could serve as an "expedition memory" that would be indexed by voice as wel1 as a web interface, linking people, places, activities, records (voice notes, photographs, samples). and a descriptive scientific ontology. This database would be accessible during EVAs by astronauts, annotated by the remote science team, linked to EVA plans, and allow cross indexing between sites and expeditions. We consider the basic problem, our philosophical approach, technical methods, and uses of the expedition memory for facilitating long-term collaboration between Mars crews and Earth support teams. We emphasize that a "memory" does not mean a database per se, but an interactive service that combines different resources, and ultimately could be like a helpful librarian.

  11. Cardio-respiratory adaptation to physical exercise and hypoxia after a high-altitude expedition.

    Motyka, K; Kozłowski, S

    1979-01-01

    Seven young, male subjects were tested before and immediately after 6 weeks high-mountain expedition. Cardio-respiratory measurements were performed at rest and during standard physical excercise (10 min, 100 W) when breathing atmospheric air or hypoxic mixture (14% O2 in N2). After the expedition an increased V o2 max (16% an average) and diminished heart rate response to submaximal exercise were found. This was observed during air and hypoxic mixture breathing. There was significant increase in stroke volume and cardiac output during the exercise. No significant differences in ventilatory parameters were found nor at rest or during exercise under condition of breathing atmospheric air or hypoxic mixture. No changes in erythrocyte count or haemoglobin concentration in the blood were found. The physiological changes which developed during high-mountain expedition were more dependent on physical that hypoxic training.

    Full Text Available The article is dedicated to the 60th Anniversary of the Mari Archaeological Expedition and summarizes the two decades of its studies (1996-2016 into the early cultures of the Mari region, starting from the era of the original settlement (Mesolithic, through the Neolithic-Eneolithic, Bronze Age, Early Iron Age and up to the Middle Ages. The expedition studied stations and settlements of primitive cultures, as well as unfortified and fortified settlements and necropolises. Special studies focused on formation and development of the early Mari culture, as well as the material and spiritual culture of the medieval Mari. The expedition continues its survey exploration in order to identify new archaeological sites. During the reported period, twelve monographs were published and three monographs prepared based on the expedition’s materials.

  13. An Exploration of Canadian Identity in Recent Literary Narratives of the Franklin Expeditions

    Directory of Open Access Journals (Sweden)

    Victor Kennedy

    2006-06-01

    Full Text Available Sir John Franklin’s three expeditions to the high Arctic in 1819, 1825, and 1845 have become the stuff of Canadian legend, enshrined in history books, songs, short stories, novels, and web sites. Franklin set out in 1845 to discover the Northwest Passage with the most advanced technology the British Empire could muster, and disappeared forever. Many rescue explorations found only scant evidence of the Expedition, and the mystery was finally solved only recently. This paper will explore four recent fictional works on Franklin’s expeditions, Stan Rogers’ song “Northwest Passage”, Margaret Atwood’s short story “The Age of Lead”, Rudy Wiebe’s A Discovery of Strangers, and John Wilson’s North with Franklin: the Lost Journals of James Fitzjames, to see how Franklin’s ghost has haunted the hopes and values of nineteenth-century, as well as modern, Canada.

    Kavanagh, L.; Martinez, A. O.; Burgio, M.; Zhang, J.; Expedition 360 Scientists, I.

    2016-12-01

    During Expedition 360 of the International Ocean Discovery Program (IODP), the JOIDES Resolution drilled 789 meters of lower crustal gabbro in the Southwest Indian Ocean. This hole began a multi-expedition project with the goal of one day drilling across the crust-mantle boundary for the first time. This simplified narrative of the research objectives struck a chord with media and the project received worldwide coverage in the form of over 50 stories with a total audience in the millions. This expedition is presented as a case study in science communication. A four-member education and outreach team onboard the ship acted as the point of contact for interested reporters. Major outlets that ran stories include the Australian Broadcasting Corporation, British Broadcasting Corporation, Boston Globe, Daily Express, Fox News, Nature, Smithsonian, and Chinese based Xinhua News Agency who sailed a reporter on the ship for the duration of the expedition. The majority of stories published provided accurate and favourable coverage of the project; however, a few contained critical errors and cast the expedition in a less positive light. Public reaction varied greatly depending on the article. Positive themes include interest in the scientific outcomes and encouragement of human exploration. Negative themes include the project being an inefficient use of money and a perceived risk of the drilling triggering an earthquake or volcano. Through a review of published articles and online comments, the successes and challenges faced by Expedition 360 are identified. Despite minimal preparation for media relations, the team successfully maintained a public profile while working in one of the most remote locations on Earth. Interviews were facilitated and videos, articles, and podcasts were produced onboard the ship. A simple, catchy narrative resulted in a large volume of coverage; however, this simplicity also formed the root of a number of misconceptions and issues of public concern.

  18. Studioantarctica: Embedding Art in a Geophysics Sea Ice Expedition

    2017-04-01

    Here we report on a six year collaboration developing new modes of communication using the interconnections between art and science in the context of climate science. We use the polar regions as a context for the collaboration in part because it holds a special place in the imaginations of many people. Not only is it is a part of the planet likely to be never visited be the viewer but there is a growing understanding of the role the poles play in the planet's climate. Motivated by the potential for cross-disciplinary outcomes, an artist was embedded in a science expedition to the fast sea ice around Antarctica. Both the science and art focused on ice crystal formation. Most elements of the art process had three phases, pre, during and post - as with the science. The environment largely dominated the progress and evolution of ideas. The results were multi-material and multiscale and provide a way to entrain a wide range of audiences, while also making non-didactic connections around global climate - and producing art. This built on a continuum of approaches where we have evolved from consideration and debate about synergies in approach, through to cross-fertilisation of ideas, shared labour, trial remote controlling and finally shared field experimentation. Certainly this is ground-breaking in an academic sense, but beyond this, it is proving a powerful attractor in engaging primary school students. In a class room setting we describe our work and experiences, both separately and in combination, as well as our recent experiences seeking to bridge the disciplinary divide. We then ask the students to contribute to the process of creating science-inspired art. There are complementary perspectives on the evolving process, their associated communication strands and how this drives a suite of communication and education outcomes. The need to understand how these systems are changing as the human species modifies its planet is urgent. Science around the connection between

    2004-05-01

    The NOAA Center for Atmospheric Sciences (NCAS) is sponsoring a Trans-Atlantic Saharan Dust AERosol and Ocean Science Expedition (AEROSE) aboard the NOAA Ship Ronald H. Brown in March 2004. The fundamental purpose of this aerosol cruise is to study the impacts and microphysical evolution of Saharan dust aerosol as it is transported across the Atlantic Ocean. The mission encompasses both, atmospheric and oceanographic components. Participating institutions include Howard University, NCAS lead institution, the University of Puerto Rico at Mayagüez, the Canary Institute of Marine Sciences, the Spanish Institute of Oceanography, the Laboratory of Atmospheric Physics Siméon Fongang, the University of Miami Rosenstiel School of Marine and Atmospheric Science, the University of Washington Applied Physics Laboratory, NASA Goddard Space Flight Center, the NOAA Cooperative Institute for Meteorological Satellite Studies at the University of Wisconsin-Madison, NASA Jet Propulsion Laboratory, and the NOAA/NESDIS Office of Research and Applications. This collaboration provides unique atmospheric and oceanic observations across the North Tropical Atlantic during eastward and westward tracks during a period of nearly one month. Characterization of microphysical properties of Saharan dust aerosol is done trough direct observations of mass, size, and particle number distributions, chemical composition, spatial distributions, and air chemistry. Aerosol radiative properties are studied through a suite of sensors that include a Multi-Angle Absorption Photometer (MAAP), the Marine-Atmosphere Emitted Radiance Interferometer (M-AERI), sunphotometers, and an assortment of other radiometers. Characterization of atmospheric conditions is done through a combination of over 250 radiosonde and ozonesonde launches at 3 to 5 hour intervals during the duration of the cruise and in coordination with satellite overpasses. AEROSE is also supporting the collection of bio-optics and oceanographic

    2012-09-17

    The volume of methane released through the Arctic Ocean to the atmosphere and its potential role in the global climate cycle have increasingly become the focus of studies seeking to understand the source and origin of this methane. In 2009, an international, multi-disciplinary science party aboard the U.S. Coast Guard icebreaker Polar Sea successfully completed a trans-U.S. Beaufort Shelf expedition aimed at understanding the sources and volumes of methane across this region. Following more than a year of preliminary cruise planning and a thorough site evaluation, the Methane in the Arctic Shelf/Slope (MITAS) expedition departed from the waters off the coast of Barrow, Alaska in September 2009. The expedition was organized with an international shipboard science team consisting of 33 scientists with the breadth of expertise necessary to meet the expedition goals. NETL researchers led the expedition’s initial core processing and lithostratigraphic evaluations, which are the focus of this report. This data report is focused on the lithostratigraphic datasets from the recovered vibra cores and piston cores. Operational information about the piston and vibra cores such as date acquired, core name, total length, water depth, and geographic location is provided. Once recovered, gas samples were immediately collected from cores. In addition, each core was run through the Geotek multi-sensor core logger for magnetic susceptibility, P-wave velocity, resistivity, and gamma-density measurements (Rose et al., 2010). After the samples and measurements were completed, the cores were split into working and archive halves. Visual core descriptions of the archive half was completed for each core. Samples for shipboard smear slides, coarse fractions, and XRD analyses were collected, as well as corresponding samples for post-cruise grain size analysis from the working half of each core. Line scan images of the split core surfaces were collected post-expedition. The methods used to

  18. Framing the Arctic: Reconsidering Roald Amundsen’s Gjøa Expedition Imagery

    2015-04-01

    Full Text Available In 1906 Roald Amundsen’s Gjøa Expedition returned to Norway after three years in the Arctic. The first to complete a Northwest Passage by sea, the expedition also brought back a substantial amount of ethnographic material concerning the Netsilik Inuit, with whom Amundsen and his crew had been in sustained contact during their stay on King William Island in Nunavut between 1903 and 1905. This material included a large number of photographs, forty-two of which were included as illustrations in his expedition narrative, titled Nordvest-passagen and first released in Norwegian in 1907. Focusing on a selection of published and unpublished photographs from Amundsen’s voyage and their interrelationships, this article examines the degree to which the Gjøa Expedition’s use of photography formed part of a planned project that intersected with anthropological concerns and practices of its time. My purpose is further to demonstrate that there is a discernible change in the representation of indigeneity that occurs when particular photographs were selected and then contextually reframed as illustrations in Nordvest-passagen. On the one hand, the extensive body of photographs taken in the field elaborates the close interaction between crew and Inuit recorded in Amundsen’s personal diary and published narrative, testifying to the existence of an active and dynamic contact zone. In this regard, the original photographs could arguably be read as a dialogic portrayal of the unique individuals Amundsen’s crew met while in the Arctic. On the other hand, a peculiar distancing seems to have taken place as the Gjøa Expedition’s photographs were selected and reproduced as illustrations for Amundsen’s expedition narrative. Likely connected to a desire to match his expedition narrative to existing scientific visual and literary conventions, this shift suggests Amundsen’s attempts through textual and visual means to deny the Netsilik Inuit

    2011-09-01

    Full Text Available Expedition 317 investigated the record of global sea-level change (eustasy within continental margin sedimentary sequences and how eustasy interacts with local forcing to produce preserved sedimentary architectures. The Canterbury Basin, on the eastern margin of the South Island of New Zealand, was selected to study these complex interactions because of high rates of Neogene sediment supply fromthe uplifting Southern Alps. This sediment input results in a high-frequency (~0.1–0.5 My periods record of depositional cyclicity that is modulated by the presence of strong ocean currents. The expedition recovered sediments as old as Eocene but focused on the sequence stratigraphy of the late Miocene to Recent, when global sea-level change was dominated by glacioeustasy. A transect of three sites was drilled on the continental shelf (Sites U1353, U1354, and U1351, plus one on the continental slope (Site U1352. The transectsamples the shallow-water environment most directly affected by relative sea-level change. Lithologic boundaries, provisionally correlative with seismic sequence boundaries, have been identified in cores from each site. Continental slope Site U1352 provides a record of ocean circulation and fronts during the last ~35 My. The early Oligocene (~30 MaMarshall Paraconformity was the deepest target ofExpedition 317 and is hypothesized to represent intensified current erosion or non-deposition associated with the initiation of thermohaline circulation in the region. Expedition 317 involved operational challenges for JOIDES Resolution, including shallow-water, continental-shelf drilling and deep penetrations. Despitethese challenges, Expedition 317 set a number of records for scientific ocean drilling penetration and water-depth.

    Spain encouraged, during the Bourbon dynasty, the formation of scientific expeditions, among which was the Royal Philanthropic Vaccine Expedition, an example of biopolitics applied by the state in order to protect health. The expedition went all over the world, using children as a reservoir to transport the vaccine fluid. Francisco Xavier Balmis established a human chain that arm-to-arm materialized the success of the mission. The characteristics and difficulties which children had to pass through and their contribution to the spread of the smallpox vaccine are analyzed.

    Background The change of anaerobic exercise abilities during and after a high-altitude expedition or hypoxic exposure is not well studied.To evaluate the effects of an extreme-altitude expedition on anaerobic performance,the 10-second supramaximal test and endocrine hormones were evaluated before and after an expedition to Peak Lenin.Methods Four subjects (3 male and 1 female,age (30.5+16.5) years) were recruited into the study.Three sets of tests were performed,including a basic test at sea level and 20 days before first arrival at the base camp (3600 m),a middle test done at day after returning from the summit to the base camp and the post test at the 10th day after return to the sea level.Both the supramaximal test,performed by a cycle ergometer,and body composition,performed by bioelectrical impedance analysis,were completed before the basic test and post test.The endocrine hormones including cortisol,growth hormone,testosterone,noradrenaline,adrenaline,dopamine,glucagon and β-endorphin were measured at all tests.Results Comparing the conditions before and after the expedition,the body measurement parameters were decreased after the expedition,i.e.,body weight (-4.22%,P <0.05),fat-free mass (-2.09%,P <0.01 ) and body fat (-8.95%,P=0.172).The peak power relative/body weight ratio (PP/BW) was similar ((9.70+1.97) vs (9.11+1.80) W/kg,P=0.093),while mean power/body weight ratio (MP/BW) was reduced significantly after the expedition ((9.14+1.77) vs (8.33+1.74) W/kg,P <0.05).Peak power/fat-free mass (PP/FFM),mean power/fat-free mass (MP/FFM) and fatigue index (FI) were significantly lower after the expedition (PP/FFM:(11.95+1.71) vs (10.99+1.59) W/kg,P <0.05;MP/FFM:(11.26+1.50) vs (10.04+1.55) W/kg,P<0.O05;FI (85.55±4.17)% vs (77.25±4.40)%,P<0.05).Hormone assays showed a significant increase of noradrenaline (basic vs middle,P<0.05) as well as decrease of adrenaline (P<0.05).Meanwhile,a trend towards an increase in dopamine (basic vs middle) and a

    The International Ocean Discovery Program (IODP) expeditions provide an excellent opportunity for onboard Education Officers (EO) to communicate and disseminate exciting shipboard research and discoveries to students around the world. During expedition 360, the EOs carried out 140 live webcasts, using different strategies to create an effective link between both students and scientists. Below are examples of strategies we used: -Primary school: The Beauty of Gabbro! and Life in the rocks! During the webcasts, students could virtually tour the ship, interview scientists, and see and discuss samples of the cored gabbro and minerals in thin sections. Artistic contextualization by J. Zhang, facilitated these activities. Moreover, highlighting the search for microbes in the Earth's crust , was particularly successful in engaging the students. -Middle and High school: Fun and relationships in science. Students were able to email expert scientists in the scientific discipline they chose to research and interview them during a live webcast. Some students created a song about the expedition. "on the boat - cup song - IODP project" https://www.youtube.com/watch?v=qex-w9aSV7c-University: Travels, research and the everyday life of professors onboard. We used webcasts to connect with universities in France, Japan and Italy, to create vibrant interactions between students and scientists that enabled students to get closer to their professors and understand better the life of onboard researchers. In collaboration with the science party we developed new strategies to keep in touch with students after completion of the cruise. We generated teaching kits consisting of pedaqgoical sets of pictures, exercises using onboard data, a continuously updated map "tracking geologists", and live webcasts to be organized from laboratories to schools. We already have had enthusiastic feedback from teachers that took part in our webcasts and the challenge is to continue to foster the

    Full Text Available Knowledge plays important role on having continuous improvement within organization. Highly skilled employees normally contribute their knowledge within organizations and help others. In this paper, we perform an empirical investigation to find important factors influencing expediting knowledge distribution in one of Iranian organizations. The proposed study of this paper designs a questionnaire and distributes it among a randomly selected employees and using some statistical test, the relationship between knowledge distribution as dependent variables with eight independent variables are investigated. The results of our survey confirm that informal mechanism, building a good trust within organization, having a good interaction among different units of organization, hiring highly committed employees, improving innovation, and learning capabilities within organization may help expedite distribution of knowledge within organization. However, the survey does not find any statistical evidence to believe that formal mechanism, having a good identity and stating objective had any meaningful impact on distributing knowledge within organization.

    The 2005 expedition to the Haughton-Mars Project (HMP) research station on Devon Island was part of a NASA-funded project on Space Logistics. A team of nine researchers from MIT went to the Canadian Arctic to participate in the annual HMP field campaign from July 8 to August 12, 2005. We investigated the applicability of the HMP research station as an analogue for planetary macro- and micro-logistics to the Moon and Mars, and began collecting data for modeling purposes. We also tested new technologies and procedures to enhance the ability of humans and robots to jointly explore remote environments. The expedition had four main objectives. We briefly summarize our key findings in each of these areas.

    This article examines the International High Altitude Expedition of 1935 and its significance in the life and science of Ancel Keys. Both the expedition and Keys's story afford excellent opportunities to explore the growing reach of interwar physiology into extreme climates-whether built or natural. As IHAE scientists assessed human performance and adaptation to hypoxia, low barometric pressure, and cold, they not only illuminated the physiological and psychological processes of high altitude acclimatization, but they also drew borderlines between the normal and the pathological, paved the way for the neocolonial exploitation of natural and human resources in Latin America, and pioneered field methods in physiology that were adapted and adopted by the Allied Forces during the Second World War. This case study in the physiology of place reveals the power and persistence of environmental determinism within biomedicine well into the twentieth century.

    The purpose of this paper is to outline one U.K. doctor's experience as advisor to a British commercial high altitude expedition company. Within the United Kingdom, this is pioneering work, and various aspects of the job are outlined that have evolved in response to the current medical needs and market forces. The U.K. medicolegal aspects of the work are considered in the light of there being no current case law to guide doctors in this role. With more people worldwide making use of commercial companies for expeditions with the associated duty of care, it is hoped that this will stimulate further debate on some potentially delicate issues that cross international boundaries.

    Revealing the impact of A-to-I RNA editing in RNA-Seq experiments is relevant in humans because RNA editing can influence gene expression. In addition, its deregulation has been linked to a variety of human diseases. Exploiting the RNA editing potential in complete RNA-Seq datasets, however, is a challenging task. Indeed, no dedicated software is available, and sometimes deep computational skills and appropriate hardware resources are required. To explore the impact of known RNA editing events in massive transcriptome sequencing experiments, we developed the ExpEdit web service application. In the present work, we provide an overview of ExpEdit as well as methodologies to investigate known RNA editing in human RNA-Seq datasets.

    Through the NSF-funded ARMADA Project, K-12 teachers can participate in scientific expeditions to gain a first-hand, and usually exciting, research experience. ARMADA Master Teachers decode this research opportunity that includes data collection and experimentation, into methodology development, and technology for use in their classrooms. Their experiences have broader impact because each teacher mentors other teachers in their school district and directly participates in the National Science Teachers Association Annual Convention to share the knowledge to an even broader educational audience. A science teacher, Susan Holt (from Arcadia High School in Phoenix, Arizona) participated as part of an international scientific party on a recent cruise to study the seafloor in the area of the December 26th Great Sumatra earthquake and tsunami-the Sumatra Earthquake And Tsunami Offshore Survey (SEATOS).

Overall, the experience benefited all parties: the teacher by learning and experiencing a shipboard geophysical operation; the scientists by Susan's fresh perspective that encouraged everyone to re-examine their first assumptions and interpretations; the SEATOS expedition by Susan's assistance in science operations; and the shipboard environment where she was able to break down the typical artificial barriers between the science `crew' and the ship's crew through frank and open dialogue. We present a summary of the SEATOS expedition, the
