  1. On the n-body problem on surfaces of revolution

    Stoica, Cristina

    2018-05-01

    We explore the n-body problem, n ≥ 3, on a surface of revolution with a general interaction depending on the pairwise geodesic distance. Using the geometric methods of classical mechanics we determine a large set of properties. In particular, we show that Saari's conjecture fails on surfaces of revolution admitting a geodesic circle. We define homographic motions and, using the discrete symmetries, prove that when the masses are equal, they form an invariant manifold. On this manifold the dynamics are reducible to a one-degree of freedom system. We also find that for attractive interactions, regular n-gon shaped relative equilibria with trajectories located on geodesic circles typically experience a pitchfork bifurcation. Some applications are included.

  2. Progress on hybrid finite element methods for scattering by bodies of revolution

    Collins, Jeffery D.; Volakis, John L.

    1992-01-01

    Progress on the development and implementation of hybrid finite element methods for scattering by bodies of revolution are described. It was found that earlier finite element-boundary integral formulations suffered from convergence difficulties when applied to large and thin bodies of revolution. An alternative implementation is described where the finite element method is terminated with an absorbing termination boundary. In addition, an alternative finite element-boundary integral implementation is discussed for improving the convergence of the original code.

    1993-01-01

    A method of constructing a nozzle having cooling channels comprises a shell and a liner which are formed into a body of revolution having an axis of revolution. Helical welds are formed to hold the liner and shell to each other with a channel position being defined between each pair of helical welds. Pressurized fluid which may be a gas or a liquid, is introduced between the weld pairs to outwardly bulge the material of at least one of the liner and shell to define the channels.

  5. Unsteady Newton-Busemann flow theory. Part 2: Bodies of revolution

    Science.gov (United States)

    Hui, W. H.; Tobak, M.

    1981-01-01

    Newtonian flow theory for unsteady flow past oscillating bodies of revolution at very high Mach numbers is completed by adding a centrifugal force correction to the impact pressures. Exact formulas for the unsteady pressure and the stability derivatives are obtained in closed form and are applicable to bodies of revolution that have arbitrary shapes, arbitrary thicknesses, and either sharp or blunt noses. The centrifugal force correction arising from the curved trajectories followed by the fluid particles in unsteady flow cannot be neglected even for the case of a circular cone. With this correction, the present theory is in excellent agreement with experimental results for sharp cones and for cones with small nose bluntness; gives poor agreement with the results of experiments in air for bodies with moderate or large nose bluntness. The pitching motions of slender power-law bodies of revulution are shown to be always dynamically stable according to Newton-Busemann theory.

  6. Turbulent skin-friction drag on a slender body of revolution and Gray's Paradox

    International Nuclear Information System (INIS)

    Nesteruk, Igor; Cartwright, Julyan H E

    2011-01-01

    The boundary layer on a slender body of revolution differs considerably from that on a flat plate, but these two cases can be connected by the Mangler-Stepanov transformations. The presented analysis shows that turbulent frictional drag on a slender rotationally symmetric body is much smaller than the flat-plate concept gives and the flow can remain laminar at larger Reynolds numbers. Both facts are valid for an unseparated flow pattern and enable us to revise the turbulent drag estimation of a dolphin, presented by Gray 74 years ago, and to resolve his paradox, since experimental data testify that dolphins can achieve flow without separation. The small values of turbulent skin-friction drag on slender bodies of revolution have additional interest for further experimental investigations and for applications of shapes without boundary-layer separation to diminish the total drag and noise of air- and hydrodynamic hulls.

  7. Radiation flaw detector for testing non-uniform surface bodies of revolution

    1984-01-01

    Radiation flaw detector for testing bodies of revolution with non-uniform surface, welded joints, etc., based on spatial filtration and differentiation of ionizing radiation flux has been described. The calculation of the most important unit of flaw detector - integrators - is made. Experimental studies of the sensitivity have shown, that the radiation flaw detector can be used for rapid testing of products with the sensitivity comparable with the sensitivity of radiographic testing of steel

  8. Viscous flow solutions for slender bodies of revolution at incidence

    Science.gov (United States)

    Vatsa, Veer N.

    1991-01-01

    Flow over slender prolate spheroids at incidence is examined. The incidence angle is chosen high enough to cause streamwise separation of the flow in addition to crossflow separation generally observed at lower incidence angles. The freestream Mach number for the cases investigated here is subsonic, thus precluding the use of parabolized procedures. Laminar, transitional and turbulent flow cases are investigated.

  9. An improved, robust, axial line singularity method for bodies of revolution

    Science.gov (United States)

    Hemsch, Michael J.

    1989-01-01

    The failures encountered in attempts to increase the range of applicability of the axial line singularity method for representing incompressible, inviscid flow about an inclined and slender body-of-revolution are presently noted to be common to all efforts to solve Fredholm equations of the first kind. It is shown that a previously developed smoothing technique yields a robust method for numerical solution of the governing equations; this technique is easily retrofitted to existing codes, and allows the number of circularities to be increased until the most accurate line singularity solution is obtained.

    2017-11-01

    Full Text Available The paper focuses on the triple jets interaction with a hypersonic external flow on a revolution body. The experimental model is a ogive-cylinder body with three supersonic nozzles, which are aligned along the flow direction. The freestream Mach numbers are 5 and 6. The spatial and surface flow characteristics are illustrated by the schlieren photographs and the typical pressure distribution. The results show that there are multi-wave system, separation, reattachment, multi-peak pressure, high-pressure and low-pressure zone boundaries obvious distinction in tri-jets interference flowfield. The present paper also analyzes how do the pressure ratio, the angle of attack, and Mach number effect on tri-jets interaction characteristics.

  11. Turbulent Boundary Layer Driven Acoustic Radiation of a Solid Body of Revolution.

    Science.gov (United States)

    Corriveau, Pierre Joseph

    The flow induced radiated noise from a body of revolution was measured in a large acoustic tank. Two solid bodies were constructed without appendages to minimize structural reradiation and eliminate other flow noise sources. One body remained uncoated and the other was clad with an acoustic decoupler. The bodies were propelled at several initial velocities using a pneumatic launcher. A retrieval mechanism decelerated the bodies and returned them to a starting position. To maintain a vertical flight path, the vehicles traveled downward concentric with a guide wire. Direct radiation measurements were achieved by placing hydrophones near the flight path, but away from tank boundaries. Analog data were acquired on multiple runs, and at each initial velocity, using a multi-track tape recorder. The data were digitized into 10 msec record lengths then Fourier transformed into 25 KHz spectra. One-third octave bands were used for frequency averaging. Equations of motion were developed to determine body position at any point throughout the trajectory. Acoustic sources were observed at two locations on the body: at the nose and tail. Slant ranges to the hydrophones were computed, and the acoustic source level was estimated at each source location for 1/3 octave bands from 1-20 KHZ. Only data determined to be spherically spreading were ensemble averaged by class and within run. Nose and tail 1/3 O.B. source level spectra at each speed, including confidence intervals, were computed. The averaged spectra were collapsed to a common speed (7.6 m/s) using standard scaling techniques. The coated body nose radiation is 9 dB lower than the uncoated case. Up to 8.4 m/s, similar tail radiation is measured on each vehicle. At 9.4 m/s the tail radiation is atypical and coating effects are observed. Radiation up to 8.4 m/s is governed by the trailing edge geometry while radiation at 9.4 m/s is the result of boundary layer separation. A simple acoustic model adequately predicts the measured

    Mottard, Elmo J; Loposer, J Dan

    1954-01-01

    Average skin-friction drag coefficients were obtained from boundary-layer total-pressure measurements on a parabolic body of revolution (NACA rm-10, basic fineness ratio 15) in water at Reynolds numbers from 4.4 x 10(6) to 70 x 10(6). The tests were made in the Langley tank no. 1 with the body sting-mounted at a depth of two maximum body diameters. The arithmetic mean of three drag measurements taken around the body was in good agreement with flat-plate results, but, apparently because of the slight surface wave caused by the body, the distribution of the boundary layer around the body was not uniform over part of the Reynolds number range.

  15. The use of the FFT for the efficient solution of the problem of electromagnetic scattering by a body of revolution

    Science.gov (United States)

    Gedney, Stephen D.; Mittra, Raj

    1990-01-01

    The enhancement of the computational efficiency of the body of revolution (BOR) scattering problem is discused with a view to making it practical for solving large-body problems. The problem of EM scattering by a perfectly conducting BOR is considered, although the methods can be extended to multilayered dielectric bodies as well. Typically, the generation of the elements of the moment method matrix consumes a major portion of the computational time. It is shown how this time can be significantly reduced by manipulating the expression for the matrix elements to permit efficient FFT computation. A technique for extracting the singularity of the Green function that appears within the integrands of the matrix diagonal is also presented, further enhancing the usefulness of the FFT. The computation time can thus be improved by at least an order of magnitude for large bodies in comparison to that for previous algorithms.

  16. Effect of splitter plate on unsteady flows around a body of revolution at incidence

    Science.gov (United States)

    Degani, David

    1991-01-01

    Numerical solutions of the thin-layer approximation of the 3D Navier-Stokes equations are presented for flows around an ogive-cylinder body with and without a splitter plate. It is suggested that the presence of the splitter plate prevents the interaction between flows on either side of the symmetry plane. It is concluded that, as a result of the enforced symmetry, the antisymmetric mode of the convective instability near the apex of the body cannot be excited and, therefore, the vortices remain symmetric, staying low and parallel to the upper body surface. The antisymmetric mode of the absolute instability mechanism cannot be initiated, which suppresses the alternate shedding of vortices from the cylindrical portion of the body. High-frequency fluctuations of the shear layer are found to remain virtually unaffected by the presence of the splitter plate.

  19. Drag of a Supercritical Body of Revolution in Free Flight at Transonic Speeds and Comparison with Wind Tunnel Data

    Science.gov (United States)

    Usry, J. W.; Wallace, J. W.

    1971-01-01

    The forebody drag of a supercritical body of revolution was measured in free flight over a Mach number range of 0.85 to 1.05 and a Reynolds number range of 11.5 x 10 to the 6th power to 19.4 x 10 to the 6th power and was compared with wind-tunnel data. The forebody drag coefficient for a Mach number less than 0.96 was 0.111 compared with the wind-tunnel value of 0.103. A gradual increase in the drag occurred in the Langley 8-foot transonic pressure tunnel at a lower Mach number than in the Langley 16-foot transonic tunnel or in the free-flight test. The sharp drag rise occurred near Mach 0.98 in free flight whereas the rise occurred near Mach 0.99 in the Langley 16-foot transonic tunnel. The sharp rise was not as pronounced in the Langley 8-foot transonic pressure tunnel and was probably affected by tunnel-wall-interference effects. The increase occurred more slowly and at a higher Mach number. These results indicate that the drag measurements made in the wind tunnels near Mach 1 were significantly affected by the relative size of the model and the wind tunnel.

    The Ptolemaic system of the universe, with the earth at the center, had held sway since antiquity as authoritative in philosophy, science, and church teaching. Following his observations of the heavenly bodies, Nicolaus Copernicus (1473-1543) abandoned the geocentric system for a heliocentric model, with the sun at the center. His remarkable work, On the Revolutions of Heavenly Spheres, stands as one of the greatest intellectual revolutions of all time, and profoundly influenced, among others, Galileo and Sir Isaac Newton.

  5. Effects of Body Mass Index on Children's Physical Activity Levels in School-Based "Dance Dance Revolution".

    Science.gov (United States)

    Pope, Zachary; Chen, Senlin; Pasco, Denis; Gao, Zan

    2016-06-01

    "Dance Dance Revolution" (DDR) (Konami Digital Entertainment, Inc., El Segundo, CA) has been recognized as an innovative approach to promote children's physical activity (PA). Previous works have described children's body mass index (BMI) status by group, but no studies have determined PA by category of BMI (underweight, normal weight, overweight, or obese). Therefore this study's purpose was to examine children's PA levels in DDR across different BMI groups. Participants were 160 third through sixth grade urban children (79 girls; 115 white) who participated in a weekly 30-minute DDR program for 18 weeks. Children's BMI was calculated based on height and weight. Levels of PA and sedentary behavior in DDR were assessed by ActiGraph(®) accelerometers (ActiGraph, LLC, Pensacola, FL) for three sessions. Outcome variables were percentages of time spent in sedentary behavior, light PA, and moderate-to-vigorous PA (MVPA). Approximately one-third (32.5%) of children fell into the overweight (n = 26) or obese (n = 26) groups. One-way (overweight/obese versus normal weight) multivariate analysis of covariance with DDR skill level as covariate yielded a significant group effect (F3, 154 = 4.02, P < 0.01). Follow-up tests indicated normal weight children accumulated significantly more MVPA (F = 8.94, P < 0.01) but less sedentary behavior (F = 3.27, P = 0.07) and light PA (F = 3.77, P = 0.054) while playing DDR than overweight/obese children. Overweight/obese children were less physically active than normal weight children during DDR. Consequently effective strategies are needed to stimulate these children to engage more actively in DDR experiences.

    Goradia, S. H.; Bobbitt, P. J.; Harvey, W. D.

    1989-01-01

    Computational experiments have been performed for a few configurations in order to investigate the effects of external flow disturbances on the extent of laminar flow and wake drag. Theoretical results have been compared with experimental data for the AEDC cone, for Mach numbers from subsonic to supersonic, and for both free flight and wind tunnel environments. The comparisons have been found to be very satisfactory, thus establishing the utility of the present method for the design and development of laminar flow configurations and for the assessment of wind tunnel data. In addition, results of calculations concerning the effects of unit Reynolds numbers on transition are presented. In addition to the AEDC cone, computations have been performed for an ogive body of revolution at zero angle of attack and supersonic Mach numbers. Results are presented for transition Reynolds number and wake drag for external disturbances corresponding to free air and the test section of the AEDC-VKF tunnel. These results have been found to compare quite well with wind tunnel data for cases when surface suction is applied as well as when suction is absent.

  11. Flight Measurements of Average Skin-Friction Coefficients on a Parabolic Body of Revolution (NACA RM-10) at Mach Numbers from 1.0 to 3.7

    Loposer, J. Dan; Rumsey, Charles B.

    1954-01-01

    Measurement of average skin-friction coefficients have been made on six rocket-powered free-flight models by using the boundary-layer rake technique. The model configuration was the NACA RM-10, a 12.2-fineness-ratio parabolic body of revolution with a flat base. Measurements were made over a Mach number range from 1 to 3.7, a Reynolds number range 40 x 10(exp 6) to 170 x 10(exp 6) based on length to the measurement station, and with aerodynamic heating conditions varying from strong skin heating to strong skin cooling. The measurements show the same trends over the test ranges as Van Driest's theory for turbulent boundary layer on a flat plate. The measured values are approximately 7 percent higher than the values of the flat-plate theory. A comparison which takes into account the differences in Reynolds number is made between the present results and skin-friction measurements obtained on NACA RM-10 scale models in the Langley 4- by 4-foot supersonic pressure tunnel, the Lewis 8- by 6-foot supersonic tunnel, and the Langley 9-inch supersonic tunnel. Good agreement is shown at all but the lowest tunnel Reynolds number conditions. A simple empirical equation is developed which represents the measurements over the range of the tests.

    Full Text Available Change and continuity are characteristics of human history. Strategic change in any society has significant impacts that becomes reference points for similar transformation in the near future. Fundamentally, the numerous internal upheavals that characterized North Africa and Middle East that culminated in a change of government in these countries has raised fundamental question about subject of change and revolution. Such questions include: is every change a revolution and does every revolution culminate in a change? What are the distinguishing features of change and the significance of such change for contemporary international politics? Using secondary data derived from books, and journals, the paper therefore examines the revolution and change in international politics drawing from historical examples of America and France Revolution. Also, noting the causes and implications of these of revolution on International Relations. It also seeks to distinguish between socio-political upheaval and internal disruptions that may culminate in change from revolution, that is, a vital change that affects institution, structure and value system of a society. The paper recommends a cautious use of the term revolution from change of government.

    INTRODUCTION The tradition of the 1956 Hungarian revolution played a major role in undermining the legitimacy of the one-party state in 1988–89. However, the post-mortem victory of Imre Nagy over János Kádár, the glorious revival of the tradition of the revolution, coincided with the dissolution of the very same tradition. Recently, as the 50th anniversary of the revolution approached, the memory and celebration of 1956 became the most controversial historical and ideological issue in the Hun...

    Over the past few years a series of finite element computer programs have been developed at Texas A and M University for the static and dynamic nonlinear analysis of shells of revolution. This paper discusses one of these, DYNAPLAS, which is a program for the transient response of ring stiffened shells of revolution subjected to either asymmetric initial velocities or to asymmetric pressure loadings. Both material and geometric nonlinearities may be considered. (Auth.)

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

  4. The Science of Structural Revolutions

    Full Text Available A perspective on the very human process by which scientific paradigms change can help point the path forward in any science, or in an applied science, such as Structural Engineering. Understanding this process of change, we can examine earthquake engineering, seismic building codes and theories of structural engineering for earthquake loads. When we take this perspective, we recognize that Structural Engineering for earthquake resistance is in the midst of a number of revolutions, from paradigms embodied in current building codes in which earthquake demands are associated with forces, to a new paradigm in which earthquake demands are re-envisioned as resulting from structural displacements or drift. The new paradigm is embodied in the current national standard for the seismic rehabilitation of existing structures, ASCE 41 [2] and the emerging standards for performance-based earthquake engineering (PBEE. Associated with this is the shift from design oriented towards life-safety to design for a range of performance objectives, such as life-safety, damage reduction, or immediate occupancy. With this perspective, we further recognize deficiencies in research and development. We have failed to systematically use the experimental and computational tools we possess to fill in the gaps of scientific knowledge. We have not developed and deployed appropriate frameworks to collect and share ideas and results. As one example, the formulation of performance-based codes now outstrips the knowledge-base needed to ensure that structures designed by the new tools will meet their performance objectives.

  5. Cultural Dimension of Revolution: New Images of Man

    Full Text Available The turning points of the history are characterized by people’s active participation in one of the most natural for the man social activity – the creation of new self-images. Being incorporated in these images, people are able to realize their involvement in social events. The new ideas and meanings acquire “corporality” in the new images of man and get accumulated in them becoming the reality accessible for the majority of people. Being revealed in the images of people, new ideas obtain real bodies, penetrate to the living tissue of culture, transform into reality, which can be perceived. Man uses their body as a tool for coding significant cultural meanings. The rules of behavior, public manners, the elements of appearance and clothing become the material signs of nonmaterial ideas. They transform into the complex distinguishing system, which allows for the consolidation of people with similar viewpoints. The creation of new visual images comes in hand with the experiments in the field of creating a new language. The authors demonstrate the appearance and creation of such images using the examples of Great French revolution, the revolutionary transformations of Post-reform Russia, Great Russian revolution, cultural revolution of the Chinese People’s Republic. M.M. Zagorulko and I.A. Petrova represent common theoretical approaches to the analysis of cultural revolutions of the New Time and Modern period, to understanding the principles of interaction between the “old” and the “new” in culture. I.A. Petrova carries out analysis of theoretical disputes of A.V. Lunacharsky and A.A. Bogdanov about the possibility of constructing “pure proletarian culture”. I.K. Cheremushnikova proves the significance of emblematic images in the culture, the connection between body self-representation and the privileged meanings, adopted during the revolution; she represents numerous examples of man becoming the carrier of new cultural meanings

  6. Implications of the sexual revolution.

    1982-06-01

    2 sexual revolutions have occurred in the last 30 years: an immense increase in knowledge of sexual matters and the accompanying expansion of providing therapy for sexual disorders; and a radical change in sexual attitudes and behavior. Discussion focuses on the ethical implications of these changes. The standards of sexual morality in this society are derived from the Judeo Christian tradition. In the beginning of Genesis there are 2 passages which are fundamental for the origin and understanding of traditional morality. In these 2 passages sexuality is first linked with establishing a man woman permanent relationship and secondly as the means of giving rise to new life. The origins of the standard Christian mortality about sex was that it was good for procreation and procreation was confined to marriage. All sexual activity before marriage and outside marriage was condemned; fornication and adultery were both wrong. This tradition of confining sex to marriage for the purpose of procreation has continued to the present when it has been widely challenged and contravened. The advent of birth control has had a pronounced effect. For the 1st time sexual intercourse and procreation are totally and effectively separated. As a result sexual activity in previously forbidden situations is now rampant. There exists an extensive preoccupation with sex. Many lavish praise on love making, yet it all depends on what is meant by lovemaking. There are at least 3 ways of understanding lovemaking: solitary sex; transient sex between a couple; and sexual intercourse within marriage. There are single people who extol solitary sex, people who insist that they do not need other people in their life. Masturbation has a place in the life of adolescents and may reassert itself when men and women are separated, but the pleasure of mutual involvement is so much greater that masturbation readily yields to heterosexual activity in the majority of cases and homosexual activity in a small

  7. Origins of the cognitive (r)evolution.

    The well documented cognitive "revolution" was, to a large extent, an evolving return to attitudes and trends that were present prior to the advent of behaviorism and that were alive and well outside of the United States, where behaviorism had not developed any coherent support. The behaviorism of the 1920 to 1950 period was replaced because it was unable to address central issues in human psychology, a failure that was inherent in part in J. B. Watson's founding manifesto with its insistence on the seamless continuity of human and nonhuman animal behavior. The "revolution" was often slow and piecemeal, as illustrated by four conferences held between 1955 and 1966 in the field of memory. With the realization that different approaches and concepts were needed to address a psychology of the human, developments in German, British, and Francophone psychology provided some of the fuel of the "revolution."

    Some of the most important things in life are taken for granted, and nowhere is this truer than with light. In this article, we will look at some important milestones marking light's path from human evolution to sustainable revolution, challenges facing the modern lighting industry as well as the world we live in, and what the future promises. In a sense, a new revolution is at hand. It would be hard to overestimate the fundamental importance of light as it shapes virtually everything we sense and experience.

    1985-01-01

    Despite a victorious social revolution, a self-proclaimed "revolutionary" government, and a significant post-war economic growth, Mexico has not achieved a just or equitable social system. The Mexican Revolution led to the emergence of a new bureaucratic class whose "trickle-down" development strategy sacrificed social welfare to capital accumulation. Mexican morbidity and mortality patterns resemble those of more impoverished developing nations without revolutionary experience. The patterns of health care in Mexico reflect inequities and contradictions in the society and economy at large and flow from the erosion of the egalitarian aims of the revolution concomitant with the expansion of capitalism and the concentration of the benefits of "modernization" in the hands of privileged elites. Mexico's health problems are symptomatic of a general socio-economic malaise which questions the legitimacy of the Revolution.

  16. Axisymmetric vibrations of thick shells of revolution

    1983-01-01

    Axisymmetric shells of revolution are used for chemical plants, nuclear power plants, aircrafts, structures and so on, and the elucidation of their free vibration is important for the design. In this study, the axisymmetric vibration of a barrel-shaped shell was analyzed by the modified thick shell theory. The Lagrangian during one period of the vibration of a shell of revolution was determined, and from its stopping condition, the vibration equations and the boundary conditions were derived. The vibration equations were analyzed strictly by using the series solution. Moreover, the basic equations for the strain of a shell and others were based on those of Love. As the examples of numerical calculation, the natural frequency and vibration mode of the symmetrical shells of revolution fixed at both ends and supported at both ends were determined, and their characteristics were clarified. By comparing the results of this study with the results by thin shell theory, the effects of shearing deformation and rotary inertia on the natural frequency and vibration mode were clarified. The theoretical analysis and the numerical calculation are described. The effects of shearing deformation and rotary inertia on the natural frequency became larger in the higher order vibration. The vibration mode did not much change in both theories. (Kako, I.)

For some, these events are coincidental and spontaneous protest ''dreamers of democracy'', while for others it is a result of the planned implementation of projects for a global reorganization of the world. Besides the difference in the value perception of ''colored revolutions'', among theorists there is no agreement even on issues of their target orientation and of their relationship to democracy, social reasonableness, and especially of compatibility of goals and the methods for their realizations.

  18. Toward a Rethinking of the Relativity Revolution

    2014-03-01

    This journey in the history of physics is offered in celebration of David Cassidy's Pais Prize. The journey, undertaken in part with the community of historians of physics and in part not, starts from a conventional characterization of the relativity revolution as an abrupt transition, in 1905, from pre-Einsteinian darkness to Einsteinian light, and ends with an alternative perspective on the relativity revolution, seeing it as a process extending over 50 years, in two phases: first, the protorelativity phase, lasting from the early 1880s to 1905, and involving initial treatments of the length contraction, the mass increase, and invariance properties; second, the Einsteinian phase, beginning with his recasting of the basic theoretical framework--with the inclusion now of the time dilation and the E = mc2 relationship--and continuing with the ensuing competition between the protorelativistic and Einsteinian approaches, issuing in the final triumph of the Einsteinian approach only in the early 1930s. A proper appreciation of the character and importance of the protorelativity phase of the relativity revolution is relevant to a variety of contexts: for the teaching of relativity theory, it makes available a more concrete and pictorial approach to the relativistic effects--retaining greater (length contraction) or somewhat lesser (mass increase) validity to the present day; for the ongoing discourse on the nature of scientific revolutions, it provides a perspective on the intricacies and complexities of those occurrences, and on the elements of continuity and gradualism in even the most radical changes; and for our general understanding of historical process in the history of the sciences, it shows the importance of the broader scientific research community for even the most individual accomplishments.

    A significant increase in shoot biomass and seed yield has always been the dream of plant biologists who wish to dedicate their fundamental research to the benefit of mankind; the first green revolution about half a century ago represented a crucial step towards contemporary agriculture and the development of high-yield varieties of cereal grains. Although there has been a steady rise in our food production from then onwards, the currently applied technology and the available crop plants will not be sufficient to feed the rapidly growing world population. In this opinion article, we highlight several below-ground characteristics of plants such as root architecture, nutrient uptake and nitrogen fixation as promising features enabling a very much needed new green revolution.

    Full Text Available Study of the problem of “class character” of 1917’ revolution and competency of the term “proletarian revolution”. The author considers questions of participation of various social groups in the Russian revolution, draws analogies of social composition of previous revolutions, considers the principle of “proletarian revolution”, as an ideology element for positioning of Bolsheviks and power capture. It is necessary to consider that an age, gender and national factor played much bigger role un Russian revolution than class factor. Revolution in Russia in many respects leaned on young generations which made more than a third of the population of the Russian Empire by 1917. In fight against tsarism separate calculation was based on the non-russian population and national suburbs of the empire. The special role in the Russian revolution was played by the peasantry. Revolution happened in the capital (in two capitals in Russia, the peasantry remained indifferent to revolution while Bolsheviks didn't begin to take away from them the food violently. This period:(summer - fall of 1919 became the time of peak of the Civil war. However return of landowners and their claim for property of the land forced peasants to turn bayonets for revolution and the earth and, eventually, to provide to Bolsheviks a victory in the Civil war.

We illustrate the theory with classical examples describing the dynamics of solids of revolution rolling without sliding on a plane. In these cases, using the existence of two conserved quantities we obtain, by means of gauge transformations and symmetry reduction, genuine Poisson brackets describing the reduced dynamics.

    Nuclear material shipping containers have shells of revolution as basic structural components. Analytically modeling the response of these containers to severe accident impact conditions requires a nonlinear shell-of-revolution model that accounts for both geometric and material nonlinearities. Existing models are limited to large displacements, small rotations, and nonlinear materials. The paper presents a finite element model for a nonlinear shell of revolution that will account for large displacements, large strains, large rotations, and nonlinear materials

    2017-01-01

    Full Text Available Using original documents from the Russian State Military Historical Archive, many of which are introduced for the first time, the author reveals details of creation and activities of the Serbian Volunteer Corps formed from captured soldiers and officers of the Austro-Hungarian army inOdessain the Summer 1916. The same autumn it received a baptism of fire in Dobruja fighting in the separate corps of the Russian army under the command of General Zayonchkovsky. The research interest in studying the activities of “national” and "international" military units within the Russian army is connected with the question of expediency and effectiveness of using such forces against those for whom they have not so long ago shed blood. The author, contrary to the popular opinion of Serbian historians, shows that the call to join the First Serbian division did not arouse mass enthusiasm among the prisoners of war both Serbs and representatives of other Yugoslav nations because of well-founded fears for their close relatives living in the Dual Monarchy and a fairly comfortable stay in the Russian captivity. At the same time, the author emphasizes that this military unit, commanded by officers of the Serbian regular army, was considered by the political leadership ofSerbiaas the basis of the future armed forces of the new state ofYugoslavia. The article shows that the events of the Russian Revolution of 1917 influenced the future fate of this military formation. Many of its soldiers later found themselves on different sides of the front in the Russian civil war. A special attention is payed to the interethnic conflict erupted in the corps between the Serbs on the one side and the Croats and Slovenes on the other. The author introduces a significant body of primary documents showing the nuances of relations in the corps between representatives of various Yugoslav nations.

    1981-01-01

    The characteristics of the Cuban demographic revolution associated with the main economic, political, and social changes in the country are analyzed. The authors begin with a brief historical outline of the political-economic situation in the country in the middle of the 19th century. There is emphasis on the dependency of the Cuban economy and its monoproducer nature (with sugar being the major export). This was due to the Spanish colonization and to the subsequent American neocolonization. The discovery of the cause for yellow fever by a Cuban physician and the sanitation campaign conducted by the Americans contributed to a diminishing of mortality. A great migratory flow occurred due to the price of sugar in the world market. This must have influenced Cuban demographic patterns which are a major factor linked to the demographic revolution. The influence on proliferation of urbanization and educational trends is emphasized. The low participation in economic activities of women during the early part of the century did affect fertility levels. The trends in mortality throughout the period 1907-43 are pointed out. It was found that 1 major aspect which had a bearing on Cuban demographic patterns was the 2 large migratory flows. An analysis of growth rates in the population--which also confirms the demographic changes in Cuba--is presented. It is concluded that the 4th decade of this century witnessed Cuba's entry in a new stage of the demographic revolution, a stage in which decreased fertility and mortality go together to create a new period.

    The aim of this paper is to analyze the impact of the so-called “shale oil revolution” on oil prices and economic growth. We employ a general equilibrium model of the world oil market in which Saudi Arabia is the dominant firm, with the rest of the producers as a competitive fringe. Our results suggest that most of the expected increase in US oil supply due to the shale oil revolution has already been incorporated into prices and that it will produce an additional increase of 0.2% in the GDP of oil importers in the period 2010–2018. We also employ the model to analyze the collapse in oil prices in the second half of 2014 and conclude that it was mainly due to positive unanticipated supply shocks. - Highlights: • We analyze the impact of the “shale oil revolution” on oil prices and economic growth. • We employ a general equilibrium model of the oil market in which Saudi Arabia is the dominant firm. • We find that most of the shale oil revolution is already priced in. • We also analyze the decline in oil prices in the second half of 2014. • We find that unanticipated supply shocks played the major role in the fall.

    The CEASEMT system of calculation by finite elements is used to determine critical internal pressures on a flattened ellipsoid of revolution. This case resembles that of an ellipsoidal head of a thin pressure vessel fitted onto a flexible colla. The calculations are performed assuming the geometry perfect, the deformations slight and the behaviour of the material perfectly elastic. The results obtained are presented favourably by plotting a reduced pressure p* against the geometry. A good definition of p* would be: p*=pπ 2 E/1-μ 2 .e 2 b 2 /a 4 (p* critical pressure, E Young's modulus, μ Poisson's coefficient, e thickness, a half large axis, b half small axis). When a/b is above 2 the p value remains close to 1. For lower a/b values the p value rises considerably with a/b [fr

    1975-01-01

    DYNAPLAS is a program for the transient response of ring stiffened shells of revolution subjected to either asymmetric initial velocities or to asymmetric pressure loadings. Both material and geometric nonlinearities may be considered. The present version, DYNAPLAS II, began with the programs SAMMSOR and DYNASOR. As is the case for the earlier programs, a driver program, SAMMSOR III, generates the stiffness and mass matrices for the harmonics under consideration. A highly refined meridionally curved axisymmetric thin shell of revolution element is used in conjunction with beam type ring stiffeners in the circumferential direction. The shell element uses a cubic displacement function and through static condensation a basic eight degree of freedom element is generated. The shell material may be isotropic or orthotropic. DYNAPLAS II uses the 'displacement' method of analysis in which the nonlinearities are treated as pseudo loads on the right-hand side of the equations of motion. The equations are written for each Fourier harmonic used in representing the asymmetric loading components, and although the left-hand side of the equations is uncoupled, the right-hand side is coupled by the nonlinear pseudo loads. The strain displacement equations of Novozhilov are used and the incremental theory of plasticity is used with the von Mises yield condition and associated flow rule. Either isotropic work hardening or the mechanical sublayer model may be used. Strain rate effects may be included. Either the explicit central difference method or the implcit Houbolt method are available. The program has found use in the analysis of containment vessels for light water reactors

    Karageorge, Panos D; Smilansky, Uzy

    2008-01-01

    We consider eigenfunctions of the Laplace-Beltrami operator on special surfaces of revolution. For this separable system, the nodal domains of the (real) eigenfunctions form a checkerboard pattern, and their number ν n is proportional to the product of the angular and the 'surface' quantum numbers. Arranging the wavefunctions by increasing values of the Laplace-Beltrami spectrum, we obtain the nodal sequence, whose statistical properties we study. In particular, we investigate the distribution of the normalized counts ν n /n for sequences of eigenfunctions with K ≤ n ≤ K + ΔK, where K, ΔK element of N. We show that the distribution approaches a limit as K, ΔK → ∞ (the classical limit), and study the leading corrections in the semi-classical limit. With this information, we derive the central result of this work: the nodal sequence of a mirror-symmetric surface is sufficient to uniquely determine its shape (modulo scaling)

    Antoine Lavoisier, the pioneering French chemist who (together with Joseph Priestley in England) identified oxygen as an element and gave it its name, in 1789 concluded that quartz was probably a compound with an as-yet undiscovered but presumably extremely common element. That was also the year in which the French Revolution broke out. Five years later, the Jacobins accused Lavoisier of offences against the people and cut off his head, thereby nearly cutting off the new chemistry. It was not until 1824 that Jöns Berzelius in Sweden succeeded in confirming Lavoisier's speculation by isolating silicon. Argument at once broke out among the scientific elite as to whether the newly found element was a metal or an insulator. It took more than a century to settle that disagreement decisively: As so often, when all-or-nothing alternatives are fiercely argued, the truth turned out to be neither all nor nothing.

  14. French revolution or industrial revolution?

    At the end of the eighteenth century, England and France both underwent revolutions: France the French Revolution, England the industrial revolution. This note sheds new light on these contrasting experiences in the histories of England and France by looking at the evolution of real consumer prices...... to maintain a decent living, and often had to cut consumption to make ends meet. The exercise conducted in the present paper gives a quantitative and economic underpinning to the notion that the French revolution did not arise out of nowhere, but rather had its roots in centuries of hardship amongst working...

    Three great physical revolutions are studied here: the theory of relativity (general and restricted); the quantum mechanics (and its different interpretations); the theory of the determinist chaos (its pre-history as its applications). These three theories contribute to modify the answers that it is possible to bring to great metaphysical questions and to give a hint of a new philosophical landscape. (N.C.)

  18. Kuhn's "The structure of scientific revolutions" revisited

    CERN Document Server

    Arabatzis, Theodore

    2012-01-01

    The year 2012 marks the 50th anniversary of the publication of Thomas S. Kuhn's The Structure of Scientific Revolutions. Up until recently, the book's philosophical reception has been shaped, for the most part, by the debates and the climate in philosophy of science in the 1960s and 1970s; this new collection of essays takes a renewed look at this work. This volume concentrates on particular issues addressed or raised in light of recent scholarship and without the pressure of the immediate concerns scholars had at the time of the Structure's publication. There has been extensive research on all of the major issues concerning the development of science which are discussed in Structure, work in which the scholars contributing to this volume have all been actively involved. In recent years they have pursued novel research on a number of topics relevant to Structure's concerns, such as the nature and function of concepts, the complexity of logical positivism and its legacy, the relation of history to philosophy o...

  1. From the Revolution to Embodiment: 25 Years of Cognitive Psychology.

    Science.gov (United States)

    Glenberg, Arthur M; Witt, Jessica K; Metcalfe, Janet

    2013-09-01

    In 1988, the cognitive revolution had become institutionalized: Cognition was the manipulation of abstract symbols by rules. But, much like institutionalized political parties, some of the ideas were becoming stale. Where was action? Where was the self? How could cognition be smoothly integrated with emotions, with social psychology, with development, with clinical analyses? Around that time, thinkers in linguistics, philosophy, artificial intelligence, biology, and psychology were formulating the idea that just as overt behavior depends on the specifics of the body in action, so might cognition depend on the body. Here we characterize (some would say caricature) the strengths and weaknesses of cognitive psychology of that era, and then we describe what has come to be called embodied cognition: how cognition arises through the dynamic interplay of brain controlling bodily action controlling perception, which changes the brain. We focus on the importance of action and how action shapes perception, the self, and language. Having the body in action as a central consideration for theories of cognition promises, we believe, to help unify psychology. © The Author(s) 2013.

  4. Nonlinear viscoelastic behaviour of shells of revolution under arbitrary loading

    International Nuclear Information System (INIS)

    Leonard, J.W.; Arbabi-Kanjoori, F.

    1975-01-01

    A formulation and solution technique are presented for the creep analysis of shells of revolution subjected to arbitrary loads and temperature changes. Arbitrary creep laws are admitted in the formulation with specific attention given to the two common laws, i.e. strain hardening and time hardening. The governing equations for creep of shells of revolution are derived. The solution method requires the quasi-static linearization of the equations: linear incremental behaviour is assumed during each time step. The incremental equations are expanded in Fourier series and solved by a numerical integration technique. (Auth.)

  5. Kuhn's Structure of Scientific Revolutions between sociology and epistemology.

    Science.gov (United States)

    Kvasz, Ladislav

    2014-06-01

    The aim of the paper is to clarify Kuhn's theory of scientific revolutions. We propose to discriminate between a scientific revolution, which is a sociological event of a change of attitude of the scientific community with respect to a particular theory, and an epistemic rupture, which is a linguistic fact consisting of a discontinuity in the linguistic framework in which this theory is formulated. We propose a classification of epistemic ruptures into four types. In the paper, each of these types of epistemic ruptures is illustrated by examples from physics. The classification of epistemic ruptures can be used as a basis for a classification of scientific revolutions and thus for a refinement of our view of the progress of science.

  6. A Short (Personal) Future History of Revolution 2.0.

    Science.gov (United States)

    Spellman, Barbara A

    2015-11-01

    Crisis of replicability is one term that psychological scientists use for the current introspective phase we are in-I argue instead that we are going through a revolution analogous to a political revolution. Revolution 2.0 is an uprising focused on how we should be doing science now (i.e., in a 2.0 world). The precipitating events of the revolution have already been well-documented: failures to replicate, questionable research practices, fraud, etc. And the fact that none of these events is new to our field has also been well-documented. I suggest four interconnected reasons as to why this time is different: changing technology, changing demographics of researchers, limited resources, and misaligned incentives. I then describe two reasons why the revolution is more likely to catch on this time: technology (as part of the solution) and the fact that these concerns cut across social and life sciences-that is, we are not alone. Neither side in the revolution has behaved well, and each has characterized the other in extreme terms (although, of course, each has had a few extreme actors). Some suggested reforms are already taking hold (e.g., journals asking for more transparency in methods and analysis decisions; journals publishing replications) but the feared tyrannical requirements have, of course, not taken root (e.g., few journals require open data; there is no ban on exploratory analyses). Still, we have not yet made needed advances in the ways in which we accumulate, connect, and extract conclusions from our aggregated research. However, we are now ready to move forward by adopting incremental changes and by acknowledging the multiplicity of goals within psychological science. © The Author(s) 2015.

  19. Instrumental traditions and theories of light the uses of instruments in the optical revolution

    CERN Document Server

    Chen, Xiang

    2000-01-01

    An analysis of the optical revolution in the context of early 19th century Britain. Far from merely involving the replacement of one optical theory by another, the revolution also involved substantial changes in instruments and the practices that surrounded them. People's judgements about classification, explanation and evaluation were affected by the way they used such optical instruments as spectroscopes, telescopes, polarisers, photometers, gratings, prisms and apertures. There were two instrumental traditions in this historical period, each of which nurtured a body of practice that exemplified how optical instruments should be operated, and especially how the eye should be used. These traditions functioned just like paradigms, shaping perspectives and even world views. Readership: Scholars and graduate students in the history of science, history of instrument, philosophy of science and science studies. Can also be used as a textbook in graduate courses on 19th century physics.

  20. Industrial revolution - industry 4.0: Are German manufacturing SMEs the first victims of this revolution?

    Directory of Open Access Journals (Sweden)

    Lutz Sommer

    2015-11-01

    Full Text Available Purpose: Industry 4.0 represents a special challenge for businesses in general and for SMEs in particular. The study at hand will examine companies´ awareness, readiness and capability to meet this challenge taking into account the special role of SMEs. Methodology: The results of nine studies dealing with this range of topics are examined in the framework of a systematic review and compared with regard to the objective of the study at hand. Findings: The review showed that, as a rule, there is an awareness concerning the relevance of the topic. The readiness and the capability to meet this challenge exist in parts; however, they strongly depend on the enterprise size. The smaller SMEs are, the higher the risk that they will become victims instead of beneficiaries of this revolution.Originality/value: Considering different studies concerning Industry 4.0 the article gives an insight into the dependence of the Industry 4.0 readiness in reference to the company size. This deepens the knowledge in adaption deficits German SME still have and opens different approaches for further research and action plans.

  1. Nematic director fields and topographies of solid shells of revolution

    Science.gov (United States)

    Warner, Mark; Mostajeran, Cyrus

    2018-02-01

    We solve the forward and inverse problems associated with the transformation of flat sheets with circularly symmetric director fields to surfaces of revolution with non-trivial topography, including Gaussian curvature, without a stretch elastic cost. We deal with systems slender enough to have a small bend energy cost. Shape change is induced by light or heat causing contraction along a non-uniform director field in the plane of an initially flat nematic sheet. The forward problem is, given a director distribution, what shape is induced? Along the way, we determine the Gaussian curvature and the evolution with induced mechanical deformation of the director field and of material curves in the surface (proto-radii) that will become radii in the final surface. The inverse problem is, given a target shape, what director field does one need to specify? Analytic examples of director fields are fully calculated that will, for specific deformations, yield catenoids and paraboloids of revolution. The general prescription is given in terms of an integral equation and yields a method that is generally applicable to surfaces of revolution.

  4. The relativity revolution from the perspective of historical epistemology.

    Science.gov (United States)

    Renn, Jürgen

    2004-12-01

    This essay analyzes Einstein's relativity revolution as part of a long-term development of knowledge in which the knowledge system of classical physics was reorganized in a process of reflection, described here as a "Copernican process." This process led in 1905 to the introduction of fundamentally new concepts of space, time, matter, and radiation. On the basis of an extensive historical reconstruction, the heuristics of Einstein's creation of the general theory of relativity, completing the relativity revolution, is interpreted as a further transformation of the knowledge of classical physics, starting from conceiving gravitation as a borderline problem between field theory and mechanics. The essay thus provides an answer to the puzzle of how Einstein was able to create a theory capable of accounting for a wide range of phenomena that were discovered only much later.

  6. Order and chaos in the rotation and revolution of a line segment and a point mass.

    Science.gov (United States)

    Lindner, John F; Lynn, Jacob; King, Frank W; Logue, Amanda

    2010-03-01

    We study the classical dynamics of two bodies, a massive line segment or slash (/) and a massive point or dot (.), interacting gravitationally. For this slash-dot (/.) body problem, we derive algebraic expressions for the force and torque on the slash, which greatly facilitate analysis. The diverse dynamics include a stable synchronous orbit, generic chaotic orbits, sequences of unstable periodic orbits, spin-stabilized orbits, and spin-orbit coupling that can unbind the slash and dot. The extension of the slash provides an extra degree of freedom that enables the interplay between rotation and revolution. In this way, the slash-dot body problem exhibits some of the richness of the three body problem with only two bodies and serves as a valuable prototype for more realistic systems. Applications include the dynamics of asteroid-moonlet pairs and asteroid rotation and escape rates.

  8. Development of Cultural Construction and Constitutional Revolution in Iran

    2017-10-01

    Full Text Available The subject of this article is the development of the cultural construction and the emergence of the Constitutional Revolution in Iran. This study, by examining the cultural structure of the Qajar era of the Naser-al-Din Shah period wants to investigate the cause of the Constitutional Revolution. The findings of this research, which have been collected by historical-analytical method, indicate that the pattern of development in the Qajar era is consistent with the pattern of unbalanced development. In this sense, by starting educational, political and military reforms in the Qajar era specially Nasser-al-Din Shah, gradually the cultural structure apart from the traditional political structure. This development provided the basis for the emergence of new intellectuals and elites with new political ideas in the field of governance methods. However, the attenuation of political structure and the backwardness of political development from cultural development faced with some obstacles. Political system instead of creating a development along with gradual cultural development and consolidating its position through the persuasion of the community, in fact to maintain integrity in the social system was resorted to force and preferred force and compulsion to persuasion. The kind of reaction and opposition of the political power structure against the modern intellectual movement, which contained new political demands in the area of governance and freedom, led to the weakness and, finally, the collapse of the Qajar political system and the constitutional revolution.

    2000-01-01

    Mexican physicians, faithful to their tradition of honor and patriotism, were present in the military and political events of the great Revolution, the began in 1910 and ended triumphantly in 1917. In the first phase, a Madero supporter and opposed to presidential reelection was doctor Francisco Vázquez Gómez, a specialist in otorhinolaryngology, Professor at the National Medical School and past President of our Academy of Medicine. The second phase of this Revolution, characterized by the struggle against the Huerta dictatorship and then by combats among revolutionary factions, also saw the intervention of many physicians and surgeons, such as senator Belisario Domínguez of Chiapas, a victim of dictatorial oppression. Among them were distinguished academicians such as doctors Rafael Silva of Mexico and Francisco Castillo Nájera of Durango. Likewise devoted nurses were in Carranza's group, while medical students enlisted in Zapata's forces. The last phase of the Revolution was dominated by the activities of the Constituent Congress in Querétaro, which promulgated the New Mexican Constitution. Among 223 elected representatives, 20 were physicians and two pharmacists (10%), who had an excellent participation in the different sessions. The new Constitution, sworn and signed on February 5, 1917, added social guarantees to individual guarantees already established by the Constitution of 1857.

  13. Literary Aftershocks of the Revolution: Recent Developments in Algerian Literature

    Directory of Open Access Journals (Sweden)

    Eric Sellin

    1980-01-01

    Full Text Available Most Algerian Francophone literature has been written since 1950, and thus the development of that literature has been intimately linked to the political events which forged the Algerian nation. Especially influential was the 1954-62 war of independence which for many years was a major contextual element in the literature. With the passage of time, the Revolution has begun to be less and less cognitive in the lives and works of the young writers. For some, Revolution lives on in the oneiric evocations of horrors glimpsed, for others it is something relegated to history, whereas for yet others it has become a political and social device. The role the Revolution plays in a writer's creativity has tended to dichotomize the literature into a conservative branch of inward- and backward-looking patriotism and a radical branch of outward- and forward-looking experimentation. Both branches present equally fervent defenses of their loyalty to their country based on a variety of arguments, but the radical branch, regardless of its relative worth in terms of internal affairs, certainly is the branch which tends to transcend national idiom and to express itself in terms of wide-spread and universal literary values.

    Directory of Open Access Journals (Sweden)

    Amr Osman

    2012-05-01

    Full Text Available While views may differ on the factors that made the 2011 Egyptian revolution possible, the role of mass media will remain undisputable. The Internet-based social networks caught the Mubarak regime by surprise, and the popular disillusionment with the ‘national’ media led the public to turn to private newspapers and satellite channels for keeping pace with the events. This paper examines the role of specific media during the 18 days of the 2011 Egyptian revolution – from 25 January to 11 February, 2011 – which we have divided into four parts. It discusses how these media contributed to the unfolding of events, conceptualized the protests and the demands of the public, and presented the actors that participated in or opposed the revolution. These points are addressed by discussing the content of the Facebook pages of the Sixth of April Movement and We Are All Khalid Said, as well as that of a private Egyptian newspaper, al-Shuruq, and the state-run newspaper al-Ahram.

    OpenAIRE

    Perrin, Stephanie Jane

    2015-01-01

    Like any social phenomenon, revolutions are gendered. The male tilt of revolutionary processes and their histories has produced a definition of revolution that consistently fails women. This thesis aims to redefine revolution to incorporate women’s visions of societal transformation and the full achievement of their rights and freedoms. I argue that approaches to women’s revolutionary experiences are enriched by focusing on the roles of culture, consciousness, and unconventional revolutionary...

  18. Cold fusion in the context of a scientific revolution in physics: History and economic ramifications

    International Nuclear Information System (INIS)

    Lewis, Edward

    2006-01-01

    Scientific revolutions have occurred in an approximately 80 year periodicity since 1500. Economic depressions have occurred at an approximately 40-50 year periodicity since 1790, and the economic depressions are a result of the scientific revolutions. The field of cold fusion is a part of a scientific revolution in physics. Understanding cold fusion phenomena in the broader historical context is helpful for understanding the development of the field and the significance of the phenomena technologically and economically. This paper includes a short history of science and of the recent scientific revolution, and includes predictions about the economic consequences of the development of the paradigm. (author)

    After the sanitary disaster caused by the first months of the conflict, the Health service of the French armies undertook a true revolution. By 1918, it had become the most efficient of all the opposing armies. At the end of 1914, through the spacing out of the evacuating hospitals within the zone of the armies, the most efficient teams were placed as close as possible to the front. Injured soldiers were categorized at every step of the chain. Technical progress, especially in war surgery, pushed medicine into the moderne era.

  1. Domestication and Crop Physiology: Roots of Green-Revolution Wheat

    2007-01-01

    Background and Aims Most plant scientists, in contrast to animal scientists, study only half the organism, namely above-ground stems, leaves, flowers and fruits, and neglect below-ground roots. Yet all acknowledge roots are important for anchorage, water and nutrient uptake, and presumably components of yield. This paper investigates the relationship between domestication, and the root systems of landraces, and the parents of early, mid- and late green-revolution bread wheat cultivars. It compares the root system of bread wheat and ‘Veery’-type wheat containing the 1RS translocation from rye. Methods Wheat germplasm was grown in large pots in sand culture in replicated experiments. This allowed roots to be washed free to study root characters. Key Results The three bread wheat parents of early green-revolution wheats have root biomass less than two-thirds the mean of some landrace wheats. Crossing early green-revolution wheat to an F2 of ‘Norin 10’ and ‘Brevor’, further reduced root biomass in mid-generation semi-dwarf and dwarf wheats. Later-generation semi-dwarf wheats show genetic variation for root biomass, but some exhibit further reduction in root size. This is so for some California and UK wheats. The wheat–rye translocation in ‘Kavkaz’ for the short arm of chromosome 1 (1RS) increased root biomass and branching in cultivars that contained it. Conclusions Root size of modern cultivars is small compared with that of landraces. Their root system may be too small for optimum uptake of water and nutrients and maximum grain yield. Optimum root size for grain yield has not been investigated in wheat or most crop plants. Use of 1RS and similar alien translocations may increase root biomass and grain yield significantly in irrigated and rain-fed conditions. Root characters may be integrated into components of yield analysis in wheat. Plant breeders may need to select directly for root characters. PMID:17940075

  5. Conrad's view of revolution/anarchism in under western eyes Conrad's view of revolution/anarchism in under western eyes

    2008-04-01

    Full Text Available It is my main purpose to discuss in this paper three relevant topics concerned with Joseph Conrad's novel Under Western Eyes, namely: the author's view of revolution and anarchism and its relation with his Polish experience; how critical Conrad is of both autocracy and revolution and finally to discuss where in, the novel the writer is sympathetic to revolution. To begin with, let me mention some aspects of Conrad's Polish background. First of all, he was a Pole, born in the Russian-occupied Poland of 1857 as the son of one of the most spirited participants in the Polish National Comittee, and with a profound fear of Russian autocratic power in his blood. Politics, nationalism, the forces of imperialism and rebellion, were the first and deepest parts of his inheritance. Conrad's character was linked to the patriotic and nationalistic ardour of his father's nature, an idealist revolutionary, and to the conservatism of his uncle Tadeuz Bobrowski his guardian during youth. The duality of thought conditioned by Apollo Korzeniowski, the father, and Tadeuz Bobrowski made his character divided all his life long. The political approach in Under Western Eyes exemplifies the writer's duality of thought. In order to write this novel Conrad found uggestions in the writings of Russian novelists, mainly Dostoievsky's Crime and Punishment. Although the book fully justifies this assertion, the writer denies it and even affirmed in a letter to a friend that he had a "Russophobia", and that he did not like the works of the famous Russian writer.

    Many dental practices today find themselves uncertain about the new social media universe, and in particular with how to relate to younger patients. The power of social networking is its immediate access to the word of mouth exchange of information, and the word of mouth avenue itself is recognized as the single most effective form of advertising. To tap into that phenomenon, begin by investing a small amount of time and effort to understand the basics of social networking. Sign up for Facebook and Twitter. First-hand experience interacting in a social network is the vital first step. The bottom line is simply this: To begin to understand this new arena of communication, you first have to join the conversation.

    Prior to 1965, the contraceptive prevalence rate (CPR) had been estimated at below 10% for the less developed regions. In contrast, over 50% of couples were using a contraceptive method in 1990. The data from the Contraceptive Prevalence Surveys and the World Fertility Survey during the 1970s provided a global overview of current patterns of contraceptive practice during 1980-81 for 76 countries, with further updates covering 97 countries around 1983, 105 countries around 1987, and 117 countries around 1990. The 105 countries covered by the 1987 update included 85% of the world's population. In China CPR was reported at 70.6% in 1982 and 72.1% in 1988. There was great variation within the subregions: while on average 17% of couples in Africa used any contraceptive method around 1987, such use was reported as 31% in northern Africa and 13% in Sub-Saharan Africa. However, in Sub-Saharan Africa CPR is expected to rise to 26% by the year 2000, corresponding to a projected total fertility rate (TFR) of 5.33 births per woman. In Asia and Oceania 53% of couples were using contraceptives around 1987. However, the CPR was 72% in eastern Asia and 40% in other countries. In Latin America, CPR was estimated at 57% in 1987. Female sterilization (tubectomy) accounted for 38% of all use in the less developed regions in 1990. Nearly 1/2 of all couples using a contraceptive method in the less developed regions undergoes female or male sterilization, as compared to about 1/6 in the more developed regions. The most commonly used methods in the more developed regions in 1990 were the pill (16%), condom (14%), and withdrawal (13%). In the less developed regions, the main methods used in 1990 were tubectomy (20%), IUD (13%), pill (6%), and vasectomy (5%). The trends in family planning will be characterized by rapid growth in the number of contraceptive users in the developing world, from 381 million in 1990 to 567 million in the year 2000. However, to meet the potential requirements of

    2003-01-01

    In an interview with J. B. McCormick of General Motors Fuel Cell Activities (GM), he answers on some questions about future of hydrogen as automobile fuel. Q: When will GM start selling cars with hydrogen propulsion? A:Our target is to start with commercial sales around 2010. Q: Why is it 2010 and not earlier or later? A: I do like the 'why not earlier' question. We had several reasons related to the pace of technical development within the GM. So far we have spent about 1 billion USD on these technologies. We have not produced too many cars though. GM is a automobile factory, we know how cars are produced so I do not have to do that. What I do have to invest into are technologies and persuade my bosses with their own personal experience that this technology can be cost effective. And therefore there is a close relation between the 2010 deadline and the technological development inside of the company. We are very close to our target of 50 USD per kilowatt including all the output and all the other required parameters. With every generation of technology the system of fuel cells is simplified. And so are the pumps and compressors. And also the material used are more suitable for mass production. The second reason is that the time has come when we have to start cooperating with governments in area of costs and tax policies and building of infrastructure. And that needs time. And not only that, time is required to design the hydrogen models and prepare for their production. Q: So from what you've just said, 2010 is an optimistic estimate. A: Yes, I think 2010 is the earliest date when a hydrogen driven car can be put on the market. Our aim is to become the first company to sell 1 million of these cars. We have strong business reasons for this. If we only wanted to claim to be the first company to offer cars using fuel cell we could produce a few cars, sell them with a loss and claim to be first. But then more and more people will buy them and the production will

It is about a transcendencecy of naive anthropology (as an embodiment of reductive mindset, that is interpretations of human nature as its corporality and transition to metaphysical anthropology which consists in upholding of unconditional priority of human thinking as associated with God.

  20. Central Bank of Ecuador, 1927: among Dictatorship, Revolution and Crisis

    Directory of Open Access Journals (Sweden)

    Cristian Paúl Naranjo Navas

    2017-01-01

    Full Text Available On July 9th, 1925, a coup d’état overthrew the Ecuadorian government of the president Gonzalo S. Córdova. The Military Junta chose the new president, Dr. Isidro Ayora, who founded the Central Bank of Ecuador in 1927. The majority of historians emphasize the patriotic spirit of the military forces in order to eliminate the influence of private banks. Nonetheless, there is a less popular view of the Julian Revolution, which understands the coup d’état, and the foundation of the Central Bank of Ecuador, as the result of struggles between bankers due to controversies around currency emissions. The arguments behind the Julian Revolution were based on some economic facts. Even though real GDP did not decrease in any year from 1913 to 1927, there was a generalized perception of a critical economy due to the constant fluctuation in prices, the increasing of fiscal deficit, and the reduction of revenues from the trade balance. The economic crisis was a common factor in the urban areas, which represented less than half percent of the total population.

  1. Nursing and the Public Health Legacies of the Russian Revolution.

    Science.gov (United States)

    Grant, Susan

    2017-11-01

    The centenary of the October Revolution in 1917 provides a timely opportunity to assess the legacies of that event. I examine the role of the revolution in public health with a focus on nursing, assessing the Imperial Russian health care system, the development of Soviet nursing, and current plans for nursing and public health care in Putin's Russia. Analyzing nursing shows that there was a great deal of continuity in terms of medical personnel and ideas on how public health care service in Russia should operate. Nursing illuminates some of the complexities of Soviet health care and ideology, particularly the state's desire to create a socialist form of nursing in theory, despite the strong links with the prerevolutionary past in the form of personnel. This situation changed after the collapse of the Soviet Union, when the new Russian state attempted to sever connections with the past, this time with the Soviet past. But as I show, making a clean break with the past is a difficult and often fraught process.

  3. Memories of Crisis: Bohr, Kuhn, and the Quantum Mechanical ``Revolution''

    Science.gov (United States)

    Seth, Suman

    2013-04-01

    ``The history of science, to my knowledge,'' wrote Thomas Kuhn, describing the years just prior to the development of matrix and wave mechanics, ``offers no equally clear, detailed, and cogent example of the creative functions of normal science and crisis.'' By 1924, most quantum theorists shared a sense that there was much wrong with all extant atomic models. Yet not all shared equally in the sense that the failure was either terribly surprising or particularly demoralizing. Not all agreed, that is, that a crisis for Bohr-like models was a crisis for quantum theory. This paper attempts to answer four questions: two about history, two about memory. First, which sub-groups of the quantum theoretical community saw themselves and their field in a state of crisis in the early 1920s? Second, why did they do so, and how was a sense of crisis related to their theoretical practices in physics? Third, do we regard the years before 1925 as a crisis because they were followed by the quantum mechanical revolution? And fourth, to reverse the last question, were we to call into the question the existence of a crisis (for some at least) does that make a subsequent revolution less revolutionary?

Similarly, scholars of the Cultural Revolution and the developments since will have much to think about and to address, because what Clark presents here is a richer and more complex narrative of recent Chinese cultural history than has heretofore been packaged or popularized. It is a narrative that underscores the continuing evolution of modern Chinese culture in the twentieth century and beyond.

    2014-04-01

    As a generalization of Newton's two body problem, we explore the dynamics of two massive line segments interacting gravitationally. The extension of each line segment or slash (/) provides extra degrees of freedom that enable the interplay between rotation and revolution in an especially simple example. This slash-slash (//) body problem can thereby elucidate the dynamics of nonspherical space structures, from asteroids to space stations. Fortunately, as we show, Newton's laws imply exact algebraic expressions for the force and torque between the slashes, and this greatly facilitates analysis. The diverse dynamics include a stable synchronous orbit, families of unstable periodic orbits, generic chaotic orbits, and spin-orbit coupling that can unbind the slashes. In particular, retrograde orbits where the slashes spin opposite to their orbits are stable, with regular dynamics and smooth parameter spaces, while prograde orbits are unstable, with chaotic dynamics and fractal parameter spaces.

  11. Impact of the Cryogen Free Revolution on Neutron Scattering Laboratories

    Science.gov (United States)

    Kirichek, Oleg

    A global shortage of helium gas can seriously jeopardise the scientific programmes of neutron scattering laboratories due to the use of cryogenic sample environment in the majority of the neutron scattering experiments. Recently developed cryogen-free technology allows a significant reduction or even a complete elimination of liquid helium consumption. Here we review the impact of the cryogen-free revolution on cryogenic equipment used at large neutron facilities, such as cryostats, dilution refrigerators, superconducting magnets and other cryogenic systems. Particular attention is given to the newly developed superconducting magnets for neutron diffraction and spectroscopy experiments. Use of the cryogen-free approach, as well as cutting-edge superconducting magnet technology and advanced neutron optics allows researcher to achieve extraordinary performance in their experiments, opening up new opportunities in neutron scattering research.

    Full Text Available Human history presents changes in various forms. These do not, however, keep up the same pace. There have been times of rapid changes and there have been times of relative stability. From ancient times to the modern world, the pace of the changes signalled in history has been relatively slow. Since the industrial revolution, however, this pace has become increasingly more intense. The mutations that have been produced have completely changed the structures of industrial production. Over the last decades, these changes and their pace of implementation have been accelerated to such an extent that they have changed the way in which we perceive the world. This article highlights the determining factors and follows the stages in the development of the great global economic powers and their fight for supremacy in the global economic equation.

  14. A Try-Out of the February Revolution?

    Full Text Available The question about the causes and actors of the February revolution can be understood only in the context of previous events. In this connection, of great importance is the analysis of the causes and circumstances of a strike wave that swept through Petrograd in October 1916. Up to 100 thousand strikers (together with locked-out workers were involved in these labor unrests that were accompanied by demonstrations and clashes with the police. In many ways (bread shortage as the main motivation, bakeshops pillage, spontaneity, suddenness, involvement of adolescents and women, Cossacks’ refusal to shoot into the crowd, solders’ desertion to the side of people, these events recall those of February 23–28, 1917. The American historians L. Haimson and E. Brian called them “a try-out of the February revolution”. Short information about these strikes is available in the papers of a number of Soviet authors; however, it is presented to some extent tendentiously, based on the desire to show the directing and organizational role of the Bolshevik party. In this regard, it seems important to restore the actual course of the events and give them an objective interpretation. The study shows that the October strikes were the first reaction of Petrograd workers to the emerging food crisis, whereas the February revolution was the reaction to the second, a much more acute phase of this crisis. The mechanism of these events was similar: in the both cases, famine was the major factor pushing for protests. In the both cases, protests were spontaneous and massive, externally similar to a hunger riot. The food crisis determined the army’s position as well: both in October and in February, Cossacks and soldiers sympathized with the starving population and refused to use weapons to crackdown demonstrators

  15. A finite element model for nonlinear shells of revolution

    Cook, W.A.

    1979-01-01

    A shell-of-revolution model was developed to analyze impact problems associated with the safety analysis of nuclear material shipping containers. The nonlinear shell theory presented by Eric Reissner in 1972 was used to develop our model. Reissner's approach includes transverse shear deformation and moments turning about the middle surface normal. With these features, this approach is valid for both thin and thick shells. His theory is formulated in terms of strain and stress resultants that refer to the undeformed geometry. This nonlinear shell model is developed using the virtual work principle associated with Reissner's equilibrium equations. First, the virtual work principle is modified for incremental loading; then it is linearized by assuming that the nonlinear portions of the strains are known. By iteration, equilibrium is then approximated for each increment. A benefit of this approach is that this iteration process makes it possible to use nonlinear material properties. (orig.)

  17. Nonlinear viscoelastic behavior of shells of revolution under arbitrary loading

    International Nuclear Information System (INIS)

    Leonard, J.W.; Arbaki-Kanjoori, F.

    1975-01-01

    The requirement of some structural components such as propulsion systems and gas turbines to operate at high temperatures and pressures make the accurate evaluation of the creep phenomenon exigent (in fast breeder reactor for example). For the expected increases in operating temperatures and pressures, it becomes necessary to perform a thorough analysis of integral structural components of nuclear power plants throughout their life span. Since a large class of structures operating at elevated temperatures are composed of rotationally symmetric shells, a solution technique can be developed which involves the numerical integration of the governing shell equations. This method has been successfully applied to the static and dynamic analysis of thin elastic shells of revolution and for some cases of inelastic material behavior. It has been shown to render solutions efficiently and accurately, usually with only a fraction of computer time and storage requirements and data manipulation that is required for other numerical schemes such as the finite element method. Furthermore, the numerical integration method allows more flexibility for varying the integration step lengths than does the finite difference method and can provide uniform accuracy throughout the analysis. For nonlinear viscoelastic behavior the numerical integration technique is expected to provide similar efficiency to that obtained for the elastic problems. The computer program developed can accept time variation of material properties. Since a single form for the material constitutive law cannot encompass all materials, provisions are made so that the analysis of a very large class of material behavior can be accomplished

  19. Elasto/visco-plastic dynamic response of shells of revolution

    International Nuclear Information System (INIS)

    Takezono, S.; Tao, K.

    1977-01-01

    The authors study the large deflection elasto/visco-plastic dynamic response of shells of revolution to strong blast loads, where the viscosity of the material is considered in the plastic range. The equations of motion and the relations between the strain and the displacement are derived from the Sanders nonlinear theory for thin shells. The constitutive relation for shell response is linear elastic, visco-plastic. In the linear elastic range Hooke's law is used. In the plastic range the elasto/visco-plastic equations by Fyfe based on the model developed by Perzyna are employed. The criterion for yielding used in this analysis is the von Mises yield theory. The numerical method selected for integration of the equations of motion is a method using finite difference in both space and time. The differential equations are written in finite difference form on the basis of the parabola method. For the time integration of the equations of motion the second-order finite difference in time is used. The equations of motion are thus expressed in finite difference form if we divide the shell into segments along meridional length and around the circumference. Resultant forces and resultant moments are given from numerical integration by Simpson's 1/3 rule. The loadings which are considered in this paper may be either impulsive or of finite time duration.

    We estimate the trend in average height of the population of the French province Orleans from 1715 to the beginning of the 19th century using data on recruits who were drafted either through a lottery system or through general conscription. After controlling for age, residence, and occupation, we find a general decline in the biological standard of living in the decades before the French Revolution. The results support a Ricardian-Malthusian interpretation of the causes of the French Revolution. In the debate 'Revolution de la misère ou de la prospérité' our findings support the side which argues that the French Revolution was a culmination of a long-lasting economic malaise during the final phases of the Ancien Régime.

    2015-01-01

    We live in a world made by science. How and when did this happen? This book tells the story of the extraordinary intellectual and cultural revolution that gave birth to modern science, and mounts a major challenge to the prevailing orthodoxy of its history. Before 1492 it was assumed that all significant knowledge was already available; there was no concept of progress; people looked for understanding to the past not the future. This book argues that everything changed with the discovery of America, which demonstrated that new knowledge was possible: indeed it introduced the very concept of "discovery", and opened the way to the invention of science. The first crucial discovery was Tycho Brahe's nova of 1572: proof that there could be change in the heavens. The telescope (1610) rendered the old astronomy obsolete. Torricelli's experiment with the vacuum (1643) led directly to the triumph of the experimental method in the Royal Society of Boyle and Newton. By 1750 Newtonianism was being celebrated throughout E...

    2015-01-01

    This new edition of Thomas Kuhn's Revolution marks the 50th anniversary of the publication of Kuhn's most influential work. Drawing on the rich archival sources at MIT, and engaging fully with current scholarship, James Marcum provides the historical background to the development of The Structure of Scientific Revolutions. Exploring the shift Kuhn makes from a historical to an evolutionary philosophy of science and examining Kuhn's legacy in depth, Marcum answers key questions: What exactly was Kuhn's historiographic revolution and how did it come about? Why did it have the impact it did? What will its future impact be for both academia and society? Marcum's answers build a new portrait of Kuhn: his personality, his pedagogical style and the intellectual and social context in which he practiced his trade. Thomas Kuhn's Revolution shows how Kuhn transcends the boundaries of the philosophy of science, influencing sociologists, economists, theologians and even policy makers and politicians. This is a comprehensi...

  9. Zombies in Revolt: The Violent Revolution of American Cinematic Monsters

    2014-06-01

    Full Text Available This paper unveils the revolutionary potential incarnated in the post-9/11 transformed figure of the cinematic zombie. It is my contention that zombies, through their cinematic (revolution, came to embody Deleuze and Guattari’s vision of the nomad war machine. Zombie films are used as a vehicle for addressing the tension between the hegemonic fear of the violent multitude in revolt and the counter-hegemonic liberatory potential of the rising masses. It is impossible to achieve a final resolution between these contradicting tendencies since the narrative structure of zombie films remains open-ended. The characteristics of the zombies and the meaning ascribed to them transform over time but they also maintain a continuity with a difference with the previous expressions of the monstrous. The monstrous characteristics which have pertained since George A. Romero’s paradigm shift in the 1960s (the zombifying contagion, violence and swarm attacks, joined with the new features appearing in the American zombie cinema of the new millennium, formulate a response to the manifest and latent violence of the State apparatus.

  10. The true revolution of nuclear will be digital

    2016-01-01

    The French nuclear industry is undergoing tremendous change. France has lost its leader place in the competition to build reactors and today's priority is to realize important competitiveness gains. Nuclear industry must become more flexible concerning the management and integration of innovation at any stage of any nuclear activity and the digital revolution will help to do so by easing cooperation between various enterprises. A joint team composed of engineers from AREVA and EDF is working in the EPR-NM project whose purpose is to re-invent the EPR reactor in order to make it more competitive by a factor 20-30%. The deployment of digital-based technologies in nuclear industry appears late when compared to other industries like aviation industry but it could benefit from the feedback experience. The additive manufacturing already exists to fabricate some small pieces of a plane. The nuclear activities that could benefit from the application of digital-based technologies like connected objects is the monitoring of the fabrication of components, the quality control and the optimization of maintenance.

    Full Text Available This article presents to the readers in Latin America the thought of the Italian liberal writer and politician Piero Gobetti (Torino 1900–Paris 1926 who was a close friend of Antonio Gramsci and one of the main intellectual influences on the work of the marxist peruvian thinker José Carlos Mariátegui. His most relevant book, La Rivoluzione Libérale, was translated into Spanish only recently but —as Mariátegui understood— some of Gobetti's ideas are very relevant to an analysis of Latin American socialformations. His very original "movement oriented" liberalism was influenced by the Russian revolution as well as by philosophers like Georges Sorel, Gaetano Mosca, Benedetto Croce and Henri Bergson.Gobetti's major concern in politics was to promote the emergence of a new ruling class. For a better comprehension of his thought, Gobetti's ideas are here compared with those of Gramsci and Mariátegui.

    During the "Green Revolution" of rice, high-yielding varieties (HYVs) were developed using a semi-dwarf gene (sd1 or OsGA20ox2). The presence or absence of the two mutant alleles (DGWG type in Dee-geo-woo-gen and JKK type in Jikkoku) were surveyed by PCR using 256 accessions of eight wild and two cultivate rice species. The DGWG allele was detected in a landrace (Oryza sativa) and two accessions of wild rice (O. rufipogon), all of which are from China, showing their limited distribution. Genealogical studies of the OsGA20ox2 gene showed that the 62 sequences of O. sativa and O. rufipogon included 20 distinct haplotypes, indicating that the species complex contained OsGA20ox2 genes from two different lineages. The silent site nucleotide diversities (pi and theta(w)) were extremely low in Japonica rice, suggesting a genetic bottleneck. The haplotype network showed that the DGWG and JKK alleles were derived in different lineages. The DGWG carrier (W1944) had unique polymorphisms in the surrounding region of the locus, suggesting that the DGWG allele has been preserved in the wild progenitor, rather than that the DGWG allele has been introgressed from HYVs to W1944. Although a semi-dwarfing plant is a weak competitor under saturated fields, the crossing experiment revealed that the DGWG variant might have been preserved as a hidden variation in the genetic background of wild rice, without expressing a short-stature.

    2018-04-09

    Today we are poised for a transition from the highly customized crafting of specific molecular targets by hand to the increasingly general and automated assembly of different types of molecules with the push of a button. Creating machines that are capable of making many different types of small molecules on demand, akin to that which has been achieved on the macroscale with 3D printers, is challenging. Yet important progress is being made toward this objective with two complementary approaches: 1) Automation of customized synthesis routes to different targets by machines that enable the use of many reactions and starting materials, and 2) automation of generalized platforms that make many different targets using common coupling chemistry and building blocks. Continued progress in these directions has the potential to shift the bottleneck in molecular innovation from synthesis to imagination, and thereby help drive a new industrial revolution on the molecular scale. © 2018 Wiley-VCH Verlag GmbH & Co.

    Full Text Available Time is one of the major considerations throughout project management life cycle and can be regarded as one of the most important parameters of a project and the driving force of project success. Time delay is a very frequent phenomenon and is almost associated with nearly all constructing projects. However, little effort has been made to curtail the phenomenon, this research work attempts to identify, investigate, and rank factors perceived to affect delays in the Egyptian construction projects with respect to their relative importance so as to proffer possible ways of coping with this phenomenon. To achieve this objective, researcher invited practitioners and experts, comprising a statistically representative sample to participate in a structured questionnaire survey. Brain storming was taken into consideration, through which a number of delay factors were identified in construction projects. Totally, ninety-nine (99 factors were short-listed to be made part of the questionnaire survey and were identified and categorized into nine (9 major categories. The survey was conducted with experts and representatives from private, public, and local general construction firms. The data were analyzed using Relative Importance Index (RII, ranking and simple percentages. Ranking of factors and categories was demonstrated according to their importance level on delay, especially after 25/1/2011 (Egyptian revolution. According to the case study results, the most contributing factors and categories (those need attention to delays were discussed, and some recommendations were made in order to minimize and control delays in construction projects. Also, this paper can serve as a guide for all construction parties with effective management in construction projects to achieve a competitive level of quality and a time effective project.

    Following the Islamic Revolution of 1979 in Iran, the trend of migration of physicians from the country continued. The total number of Iranian physicians migrated to the United States (US) increased from 1625 before revolution in 1974, to 5045 in 2010, thirty years post-revolution. The percentage of medical graduates migrating to the US, in the same period dropped from 15% to 5%. The reasons for this drop were restrictions imposed, along with creation of good postgraduate residency and fellowship programs in Iran. Following the revolution, the number of medical schools increased from 13 to 48. Despite all the restrictions and impediments for post-revolution medical graduates, over 500 medical graduates from newly established medical schools found their ways into the healthcare system of the US.     In spite of all hardships of eight years of imposed war, and 30 years of the US sanctions, Iran has been able to maintain good progress in its healthcare, education, and research in medicine and other branches of science and technology.

General revolution solid, revolution cone, revolution ellipsoid, ball, paraboloid and hyperboloid are treated. Chapter 1 represents the frictionless case. Chapter 2 deals with the friction case. The transformation from velocity to the belonging orbit height is calculated in chapter 3. In chapter 4 and 5 the macro revolution solids follow (without and with friction)is treated. The assumption of a homogeneous field is not possible here. The radial gravitational field must be used. In the last chapter we have orbits with non constant angular velocity that can be derived with the Lagrange-equations of the second kind in the frictionless case. Here is also possible to view different revolution solids. The book is recommended to all experimental-, theoretical and mathematical physicists. There is an english and a german edition.

  3. The Language of Revolution and the Power of Storytelling in The Pregnant Widow

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Martin Amis uses the language of revolution to describe the newly altered social circumstances at the height of the sexual revolution in his semi-autobiographical novel The Pregnant Widow. The concept of a ‘language of revolution’ as well as second- and third-wave feminist scholarship is applied to a textual analysis of the novel. Amis’s brand of satire creates a sense of displacement and challenges existing perceptions about gender, culture and sexuality, exposing them as constructed and changeable norms. Moreover, it becomes clear that the author is skeptical about the benefits of the sexual revolution for either gender, and that he views its liberating aspects as unfulfilled, particularly for women. Given that Amis names one of his characters Scheherazade, evoking the legendary heroine of The Arabian Nights, the importance of storytelling in the novel is also examined and found to be a potentially redeeming force.

    Full Text Available This article investigates gender implications of judicial activism within the context of the 2011 revolution. Relying on analysis of a sample of judicial decisions in the field of divorce and child-rearing, I argue that individual judges used the family courts as a platform to articulate alternative legal discourses prior to the 2011 revolution. During the period between February 2011 and the military coup in July 2013 family legislation emerged as a controversial point. The period witnessed the mobilisation of small but vocal fathers’ rights groups that called for a revolution in Egyptian family law and formed strategic alliances with a handful of judges. The latter became members of a legislative committee formed under the presidency of Muhammad Mursi. I investigate the gender implications of their activism against a background where old and new actors and institutions competed over the right to interpret shari’a in an authoritative way.

    Full Text Available The article analyzes the anti-Russian historical narrative focused on the 1917 events. The relevance of the theme is determined bythe wide-ranging discussion on the Russian revolution due toits anniversary. The authors solve the problem of the scientific criticism of the anti-Russian myths, focused on the assessments and interpretations of the two Russian revolutions of 1917. In the article there are shown the ideological basis and political context of the coverage of the events of 1917. The authors analyze 5 historical ideologemes, which are disseminated in the public consciousness. They also show the cognitive and political implications of adopting the respective ideology. As a typical liberal myth, the authors regard the interpretation of the October Revolution as “stolen freedom” provided by the February revolution. In the article there is shown that through the myth of “stolen freedom” the whole history of Russia is presented as a reproduction of the “totalitarian regime”. The authors prove the incorrectness of showing Bolsheviks as the initiators of the use of mass terror tactics, to which all major opposing forces resorted. There is considered the connection of the interpretation of the Revolution as the manifestation of the “Russian rebellion” with the Russophobic myth of the Russian barbarism. The authors criticize the idea of the Bolshevik imperialism, which is allegedly based on the ideology of world revolution. The article gives the deconstruction of the myth of the Bolshevik regime illegitimacy and shows the cognitive contradictions of the attempts to counter the concepts of “October Revolution” and “October Coup”. The authors reveal that the thesis of the Constituent Assembly, as an illustration of the Bolshevik illegitimacy, doesn’t correspondent to the historical facts. The authors conclude that the issues of covering the events of both the Revolutionand the Great Patriotic War are linked to the national

    Full Text Available Ethical uprising, enforcement of accounting guidelines and discipline by statutory accounting body is an issue of concern that need to be uphold due to the succession of corporate scandals that took place in Nigeria and the world over, thereby undermining the image of the accountancy profession. These corporate scandals in no doubt challenged the credibility of financial statements, auditing and corporate governance practices for which accountants are directly linked with. In this paper, we examined the impasse of the 21st century accountants and the need for ethical revolution, enforcement of accounting guidelines and discipline by statutory accounting body for erring accountants. Several impasses facing the 21st century accountants were identified such as expectation gap (resulting to loss of public confidence in the profession, falsifying financial statements and engaging in ‘negative accounting’ among others. Questionnaire was administered to three (3 classes of respondents (investors, auditors and accounting regulatory bodies and the data obtained were subjected to Pearson Product Moment Correlation. The study found that the impasse facing the 21st century accountants can be repealed via ethical revolution, enforcement of accounting guidelines and discipline by statutory accounting body for erring accountants. Owing to the above findings, we proposed that the accounting regulatory bodies and the government should sanction accountants and firms engaged in unscrupulous accounting practices as well as revoking the licenses of professional accountants that precipitate such actions. As a matter of fact, seminars and workshop on issues relating to ethics and accounting guidelines should be organized for professional accountants. Also, code of professional conducts should be strictly enforced on all professional accountants by the regulatory body. It is our candid believe that if these recommendations are fully implemented, it will go a long

  7. Quantum revolution

    CERN Bulletin

    2010-01-01

    The turn of the XXth century witnessed a revolution in physics comparable to Isaac Newton’s discovery of the universal laws of mechanics and of gravitation three centuries earlier. The world required to be described in novel terms, as the immutable, deterministic view of our familiar universe had given way to a new world picture, one which featured chance, flux, and an incessant upsurge of waves of matter. Such a worldview was so radically new and counterintuitive that it gave rise to strong debates, to the effect that Albert Einstein himself tried to oppose it on the grounds that “God does not play dice”. In spite of the intense debates that accompanied its emergence, quantum mechanics quickly proved an incredibly efficacious new tool to understand and to predict a wide array of new phenomena. It was so successful that in no time it broke free from the environment of research labs to become part of daily life, making it possible, for example, to understand why some materials...

    Green Revolution made a substantial contribution to wheat yields worldwide in the 1960s and 1970s. It is of great importance to analyze the haplotype variation of Rht-D1, the Green Revolution gene, during wheat (Triticum aestivum L.) domestication and breeding to understand its evolution and function in wheat breeding history. In this study, the Rht-D1 and its flanking regions were sequenced and single nucleotide polymorphisms were detected based on a panel of 45 accessions of Aegilops tauschii, 51 accessions of landraces and 80 accessions of commercial varieties. Genetic diversity in the wild accessions was much higher than that in the varieties and higher than that reported previously. Seven haplotypes (Hapl I to Hapl VII) of Rht-D1 were identified and their evolutionary relationships were proposed. In addition to the well-known Green Revolution allele Rht-D1b, Hapl VII (an allele Rht-D1k) was identified in early breeding varieties, which reduced plant height by 16%. The results suggested that Rht-D1k had been used in breeding before the Green Revolution and made a great contribution to wheat production worldwide. Based on the breeding history and molecular evidence, we proposed that the wheat Green Revolution in China and International Maize and Wheat Improvement Center (CIMMYT) occurred independently. © 2014 Institute of Botany, Chinese Academy of Sciences.

    In Tunisia, the phenomenon of self-immolation has increased dramatically since the self-burn of Mohamed Bouazizi which occurred on 17 December 2010. The aim of our study was to compare the casualties' profile of suicide by self-immolation before and after the Tunisian Revolution over a period of 10 years (2006-2015). We conducted a retrospective review including all the cases of self-immolation suicides that occurred in Northern Tunisia five years before and five years after the January 2011 Revolution. We excluded cases of self-immolations committed in governorates other than the north of Tunisia as well as casualties of accidental or criminal burns and those where the context could evoke suicidal immolation but the self-inflicted nature has not been confirmed. The study sample was subdivided in two groups according to the Revolution date: before the Revolution (2006-2010) and after the Revolution (2011-2015). We compared for each group data related to the age, gender, marital status, employment, mental disease history, previous suicide attempts and threats, place of suicide and its motive, the type of fire accelerator, the hospitalization and the average body surface area burned. The number (n=48/24.5% before 2011) of suicide by self-immolation has tripled during the post-revolution period (2011-2015) with a stable trend. The average age (35.6±13.4) has not changed. The male remained predominant before and after the Revolution (sex ratio of respectively 1.67 and 3.23). Marital status (victims being single in n=81 cases/41.3%) and the employment (unemployed in n=128/65.3%) of the casualties have not changed either after 2011. Fewer cases with psychiatric history were reported (n=21/43.7% before against n=52/35.1% after). Self-immolation increased in public places (n=9/18.7% before against n=50/33.8% after) and in an administration (n=2/4.2% before against n=19/12.8% after). More suicides after 2011 were due to financial problems (n=2/4.2% before against n=30

    We previously reported that a rotation/revolution pulverizer (NP-100) could mill a small amount of a drug (0.1 g) into nanoparticles in several minutes. In this investigation, scale up from the milligram to the kilogram scale of the nano-milling process by the rotation/revolution pulverizer was studied. Phenytoin was used as a model drug with low solubility in water. After confirming the improvement of the phenytoin bioavailability by milling to nanoparticles using NP-100, scaling parameters were evaluated using NP-100 and the middle scale model of NP-100 (ARV-3000T). A theoretical equation for the specific collisional energy was adapted for wet milling; this suggested that the relative centrifugal acceleration of revolution (revolution G) and the drug concentration in the suspension were the two most important parameters. The results obtained using NP-100 and ARV-3000T correlated well when these two parameters were identical. These results were applied to the large scale model of NP-100 (ARV-10KT), where 2 kg (1 kg x 2) of phenytoin nanoparticles were obtained in 60 min. The results from PXRD and DSC indicated that the milled phenytoin by ARV-3000T and ARV-10KT maintained its crystallinity. These results suggest nano-milling using a rotation/revolution pulverizer will be widely applicable to the development of nano-medicine.

    Full Text Available This paper applies Cartesian and Weberian theories of rationalization and Leslie Sharp’s concept of bodily commodification to the transition in the observance of Ashura from practices of bodily mortification to blood donation among the Shi‘a community in Lebanon. The author argues that this shift politicizes salvation and sacralises revolution through a process of rationalization, made possible through the invocation of the Karbala Paradigm, in order to facilitate the commodification of blood for political activism. This shift in ritual practice for the commodification of blood has occurred as a result of three key transitions: (i from body/self-unity to body/self-dualism; (ii from salvation in the next world to salvation in this world; and (iii from personal salvation to societal salvation.[Dengan merujuk teori rasionalisasi model Descartes dan Weber serta konsep komodifikasi tubuh dari Leslie Sharp, tulisan ini menelusur pergeseran yang terjadi pada ritual Ashura dari praktik melukai diri menjadi kegiatan donor darah di kalangan Syiah di Lebanon. Proses ini, menurut penulis, telah mengubah konsep penyelamatan dan revolusi sakral melalui proses rasionali­sasi. Hal ini terjadi dengan memakai Paradigma Karbala sebagai media komodifikasi darah untuk aktivisme politik. Pergeseran komodifikasi darah dalam praktik ritual ini terjadi melalui tiga transisi utama: (i dari kesatuan diri menjadi dualisme diri; (ii dari keselamatan akhirat menjadi keselamatan dunia; dan (iii dari penyelamatan pribadi menjadi penyelamatan sosial].

    We study infinitesimal bendings of surfaces of revolution with flattening at the poles. We begin by considering the minimal possible smoothness class C 1 both for surfaces and for deformation fields. Conditions are formulated for a given harmonic of a first-order infinitesimal bending to be extendable into a second order infinitesimal bending. We finish by stating a criterion for nonrigidity of second order for closed surfaces of revolution in the analytic class. We also give the first concrete example of such a nonrigid surface.

  16. A departure from cognitivism: Implications of Chomsky's second revolution in linguistics.

    Science.gov (United States)

    Schoneberger, T

    2000-01-01

    In 1957 Noam Chomsky published Syntactic Structures, expressing views characterized as constituting a "revolution" in linguistics. Chomsky proposed that the proper subject matter of linguistics is not the utterances of speakers, but what speakers and listeners know. To that end, he theorized that what they know is a system of rules that underlie actual performance. This theory became known as transformational grammar. In subsequent versions of this theory, rules continued to play a dominant role. However, in 1980 Chomsky began a second revolution by proposing the elimination of rules in a new theory: the principles-and-parameters approach. Subsequent writings finalized the abandonment of rules. Given the centrality of rules to cognitivism, this paper argues that Chomsky's second revolution constitutes a departure from cognitivism.

    CERN Document Server

    Tozzi, Christopher

    2017-01-01

    In the 1980s, there was a revolution with far-reaching consequences -- a revolution to restore software freedom. In the early 1980s, after decades of making source code available with programs, most programmers ceased sharing code freely. A band of revolutionaries, self-described "hackers," challenged this new norm by building operating systems with source code that could be freely shared. In For Fun and Profit, Christopher Tozzi offers an account of the free and open source software (FOSS) revolution, from its origins as an obscure, marginal effort by a small group of programmers to the widespread commercial use of open source software today. Tozzi explains FOSS's historical trajectory, shaped by eccentric personalities -- including Richard Stallman and Linus Torvalds -- and driven both by ideology and pragmatism, by fun and profit. Tozzi examines hacker culture and its influence on the Unix operating system, the reaction to Unix's commercialization, and the history of early Linux development. He describes ...

    2016-12-01

    Full Text Available The differences between the decentralized model of the British financial market from the centralized French (continental model emerged after the financial revolution of 1688 in England, which lasted until the end of the XVII century and had an impact on public and private finance. Due to the captivity of the French Huguenots shortly before the "Glorious Revolution" in England, new technologies appeared in the financial sector, and manifested in the creation of the first British banks. After the revolution, with the coming to power of the Dutch Prince, many financiers arrived at London and were spreading the technique of effective Dutch stock transactions. Increased interest of the society to innovation in the financial market and the emergence of new investment opportunities had a positive impact on the development of stock market, government bond market and derivatives market. This, in its turn, led to the appearance of new financial intermediaries such as jobbers, who took over the high risks because of investing of own funds in securities. Such significant changes in the financial system of England became the important prerequisite of the industrial revolution and allowed it to take the leading position in the economic, political and financial area in the world.

    During the year 2011 the Egyptian revolution arose with a change in the trend of eye trauma in Egypt. This study aims at reviewing the epidemiology of ocular trauma presenting to Ain Shams University teaching hospital during the year 2011 and comparing it with epidemiology during the previous 5 years. This is a retrospective epidemiological and clinical study of patients admitted to Ain Shams University Hospital with ocular trauma from 2006 till 2011. Cases were analyzed with respect to age, sex, occupation, admission interval, type, mode, time and place of injury, causative instrument, diagnosis and examination findings, investigations, management and visual outcomes. Total numbers of cases presenting during the year 2011 was 237 cases. The mean age was 22.5 years. Students (47.2%) and jobless people (21.9%) constituted the majority of the sample. During the year 2011 there was a significant increase in the percentage of injuries occurring in the street. There was also a significant rise in the percentage of homicidal ocular injuries specially those caused from non-rifled weapons. Fourteen cases of endophthalmitis were associated with non-rifled fire arm missiles while 7 were associated with glass intra-ocular foreign body. This indicated that the probability of occurrence of endophthalmitis with metal intraocular foreign bodies was 2:3 i.e. 66.6% where as in glass intra ocular foreign body was 7:9 i.e. 77.7%. The majority of ocular trauma in our population during the year 2011 was due to homicidal street injuries occurring mainly in males of young age group, which is consistent with the events occurring in Egypt in this year. The findings indicate that ocular trauma is a significant cause of visual loss in this population. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    The wide-spread prevalence of unimproved sanitation technologies has been a major cause of concern for the environment and public health, and China is no exception to this. Towards the sanitation issue, toilet revolution has become a buzzword in China recently. This paper elaborates the backgrounds, connotations, and actions of the toilet revolution in China. The toilet revolution aims to create sanitation infrastructure and public services that work for everyone and that turn waste into value. Opportunities for implementing the toilet revolution include: fulfilling Millennium Development Goals and new Sustainable Development Goals; government support at all levels for popularizing sanitary toilet; environmental protection to alleviate wastewater pollution; resource recovery from human waste and disease prevention for health and wellbeing improvement. Meanwhile, the challenges faced are: insufficient funding and policy support, regional imbalance and lagging approval processes, weak sanitary awareness and low acceptance of new toilets, lack of R&D and service system. The toilet revolution requires a concerted effort from many governmental departments. It needs to address not only technology implementation, but also social acceptance, economic affordability, maintenance issues and, increasingly, gender considerations. Aligned with the ecological sanitation principles, it calls for understanding issues across the entire sanitation service chain. Public-private partnership is also recommended to absorb private capital to make up the lack of funds, as well as arouse the enthusiasm of the public. Copyright © 2017 The Authors.

    2017-01-01

    Full Text Available The main link between revolutions in a polemogenic wave is participation of correspondent states in a common war (Πόλεμος – war, Γέννηση – birth. The polemogenic wave caused by the First World War includes successful revolutions (with the change of power in Russia, Germany, Hungary, the success of some national liberation movements of Irish people, Czechs, Slovaks, South Slavs, Poles, Finns, the defeat of such movements of Ukrainians, Georgians, Armenians, peoples of Turkestan, the establishment of regimes of various types and with different stability. The article presents an approach to identify causes of different types of dynamics and the consequences of revolutionary events in within the wave. The approach includes comparisons using methods of similarity and difference, as well as the application of binarization and Boolean algebra according to Ch. Ragin’s method. The application of this approach makes it possible to put forward hypotheses about causes and patterns of revolutionary dynamics and consequences in the polemogenic wave: what determines inclusion of a society into the wave, the level of loyalty of ethnic provinces in relation to their empire, success and failure of revolutions, existence and absence of civil war, relationship between revolution and religion, nature and fate of the cultural avant-garde.

    Chang, Hasok

    2015-02-01

    I respond to the critical comments by Martin Kusch and Ursula Klein on my account of the Chemical Revolution. I comment along three different lines: descriptive, explanatory, and normative. (1) I agree with Klein that Lavoisier did not introduce drastic changes in chemical ontology, but maintain that there was methodological incommensurability in the Chemical Revolution; in response to Kusch's view, I maintain that Lavoisier's victory was slow and incomplete. (2) Admitting that there were many causes shaping the outcome of the Chemical Revolution, including the convenience of Lavoisier's theoretical scheme and various complicated social factors, I still think that the general rise of compositionism was an important factor. (3) I defend my normative pluralist view on the Chemical Revolution, denying Kusch's argument that chemists had overwhelmingly good reasons to trust Lavoisier and his allies over the phlogistonists. Overall, I agree with Kusch that it would be desirable to have a good descriptive-normative sociological account of the Chemical Revolution, but I also think that it should be an account that allows for divergence in individuals' and sub-communities' self-determination.

    Full Text Available In Cuba, Revolution and education are overlapping processes, one might be impossible without the other. Three educational revolutions are identified and characterized in the paper; a definition for the term is given. Likewise, the role of teachers and educators contributing to the construction of socialism is discussed. After diagnosing pupils being trained as teachers of Marxism-Leninism and History, the lack of knowledge of the role of teachers and their contribution the educational program of the Revolution was revealed. This paper is aimed at describing the method of emotional commitment to paradigm of educators. This method helps to account the enrolment of professor of José Martí” College of Education in the task of doing a revolution in education and constructing socialism in Cuba. The novelty of the method is the revelation of the connection between landmarks and protagonists, a person who teachers’ trainees take as a paradigm in building their own personality and as the object of study in history of education research process they are carrying out.

  3. The dark side of the Scientific Revolution. The Biblical interpretation in Galileo Galilei and Isaac Newton

    Directory of Open Access Journals (Sweden)

    Francesco Fiorentino

    2015-11-01

    Full Text Available This contribution investigates a hidden and surely singular – but far from marginal – aspect of the Scientific Revolution of the 17th century, in other words the interpretation of the Holy Scriptures. First of all, this work analyzes the situation immediately before the advent of the fathers of the 17th Century Scientific Revolution like Galileo Galilei and Isaac Newton, starting from the Council of Trent. This reconstruction aims to throw light on the particular way that Galileo and Newton intended to approach the interpretation of the Holy Scriptures with respect to the main tendencies of the Catholic Reformation of biblical hermeneutics. Their way is important both in itself and in relation to the Scientific Revolution. In itself because Galileo and Newton elaborate original theories that are not entirely in agreement with the predominant views and that are decidedly no less interesting than their pure scientific theories. In relation to the Scientific Revolution because the interpretation of the Holy Scriptures is addressed in an original fashion by both Galileo and Newton, also with the intent of facilitating the spread and approval of their own scientific theories in their respective socio-cultural environments. The primacy of nature is not manifested only in contrast to and outside the book of Scriptures, but conditions the Book of Scriptures, locating it within a precise cultural perspective and religious sense that are by no means contrary to Galileo and Newton’s views.

    In this study, nanoparticles of various poorly water soluble compounds were prepared by wet milling that was carried out using a rotation/revolution mixer and zirconia balls. To be compared with Beads mill, rotation/revolution mixer has superior in very quick process (5 min) and needs very few amounts of zirconia balls (2.4 g) for pulverizing drugs to nanometer range. Phenytoin, indomethacin, nifedipine, danazol, and naproxen were selected as the standard poorly water soluble compounds. Various parameters of the rotation/revolution mixer were studied to decide the optimal pulverization conditions for the production of nanoparticles of the abovementioned compounds. The rotation/revolution speed, shape of the mixing vessel, amount of zirconia balls, and volume of the vehicle (methylcellulose solution) mainly affected the pulverization of the compounds. Using the mixer, phenytoin could be pulverized to nanoparticles within a few minutes. The particle size was confirmed by using a scanning electron microscope and a particle size analyzer. The crystallinity of the pulverized phenytoin particles was confirmed by X-ray diffractometry (XRD) and differential scanning calorimetry (DSC). It was observed that the pulverized phenytoin particles retained their crystallinity, and amorphous phenytoin was not detected. Particles of other poorly water soluble compounds were also reduced to the nanometer range by using this method.

    To analyze the impact of the Tunisian Revolution on suicide and homicide patterns in Tunisia. It is a retrospective, cross-sectional study, including all the cases of homicides and suicides that occurred during an 8-year period (2007-2014) in Northern Tunisia. We compared data before and after the revolution. After the revolution, the number of suicides rose 1.7 times, with a prevalence rising from 1.8 to 3.12 suicides per 100,000 persons per year. Homicides rose 1.3 times after the revolution. For both manner of death, victims were mostly males, aged between 20 and 39 years, living in urban areas. Hanging and self-immolation rose, respectively, 1.8 and 3 times after 2011. We observed suicide cases most frequently occurred in public places and in front of public administration after 2011. Homicide victims' profile and circumstances showed a single variation which is an increase in number of cases happening in rural areas. Our results proved a short-term impact of the transition period on homicides and suicides. Urgent preventive measures are needed especially to decrease the suicide rates.

  10. The epistemology of mathematical and statistical modeling: a quiet methodological revolution.

    Rodgers, Joseph Lee

    2010-01-01

    A quiet methodological revolution, a modeling revolution, has occurred over the past several decades, almost without discussion. In contrast, the 20th century ended with contentious argument over the utility of null hypothesis significance testing (NHST). The NHST controversy may have been at least partially irrelevant, because in certain ways the modeling revolution obviated the NHST argument. I begin with a history of NHST and modeling and their relation to one another. Next, I define and illustrate principles involved in developing and evaluating mathematical models. Following, I discuss the difference between using statistical procedures within a rule-based framework and building mathematical models from a scientific epistemology. Only the former is treated carefully in most psychology graduate training. The pedagogical implications of this imbalance and the revised pedagogy required to account for the modeling revolution are described. To conclude, I discuss how attention to modeling implies shifting statistical practice in certain progressive ways. The epistemological basis of statistics has moved away from being a set of procedures, applied mechanistically, and moved toward building and evaluating statistical and scientific models.

  11. SOHO starts a revolution in the science of the Sun

    Science.gov (United States)

    1996-07-01

    In addition, SOHO has found clues to the forces that accelerate the solar wind of atomic particles blowing unceasingly through the Solar System. By relating the huge outbursts called coronal mass ejections to preceding magnetic changes in the Sun, SOHO scientists hope to predict such events which, in the Earth's vicinity, endanger power supplies and satellites. SOHO sees differences in the strength of the solar wind in various directions, by mapping a cavity in the cloud of interstellar hydrogen surrounding the Sun. As a bonus, SOHO secured remarkable images of Comet Hyakutake, by ultraviolet and visible light. The revolution in solar science will seem more complete when all the pieces and actions of the Sun, detected by twelve different instruments, are brought together in observations and concepts. Fundamental questions will then be open to re-examination, about the origin of the Sun's magnetism, the cause of its variations in the 11-year cycle of sunspot activity, and the consequences for the Solar System at large. SOHO is greater than the sum of its parts. "SOHO takes solar science by storm," says Roger Bonnet, the European Space Agency's Director of Science, "thanks to its combination of instruments. Unprecedented results from individual telescopes and spectrometers are impressive, of course, but what is breathtaking is SOHO's ability to explore the Sun all the way from its nuclear core to the Earth's vicinity and beyond. We can expect a completely new picture of how agitation inside the Sun, transmitted through the solar atmosphere, directly affects us on the Earth." SOHO is a project of international cooperation between the European Space Agency and NASA. The spacecraft was built in Europe and instrumented by scientists on both sides of the Atlantic. NASA launched SOHO and provides the ground stations and an operations centre at the Goddard Space Flight Center near Washington. SOHO has an uninterrupted view of the Sun from a halo orbit around Lagrangian

    2017-09-01

    Before 1966, Chinese mathematician Hua Loo-Keng had singled out "Two Methods" as a way to truly applied and useful mathematics. The Overall Planning Method, based on the Critical Path Method widely used in USA, mostly appealed to middle and upper management. This limited its spread during the Cultural Revolution. The Optimum Selection Method, also of US origin, was more mass-oriented and ready for popularization. Nevertheless, Hua met resistance from leftist radicals, whose ideological objections sprang from an underlying power struggle. Hua built popularization teams, mostly from talented younger people whose careers were disrupted by the Cultural Revolution, and thus opened a path for many of them to important roles in China's scientific infrastructure after 1976. Hua Loo-Keng's efforts, while interrupted during the Cultural Revolution and the subsequent political campaigns, were also helped by the populist ethos of the movement, and by the lack of other non-political endeavors at that time. In this sense, the Cultural Revolution gave Hua Loo-Keng's popularization its importance and long-term impact. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2013-11-02

    The detection of nuclear or radioactive materials for homeland or national security purposes is inherently difficult. This is one reason detection efforts must be seen as just one part of an overall nuclear defense strategy which includes, inter alia, material security, detection, interdiction, consequence management and recovery. Nevertheless, one could argue that there has been a revolution in detection affairs in the past several decades as the innovative application of new technology has changed the character and conduct of detection operations. This revolution will likely be most effectively reinforced in the coming decades with the networking of detectors and innovative application of anomaly detection algorithms.

    Herold, Elisabeth; Hellmann, Robert; Wagner, Joachim

    2017-11-28

    We provide analytical expressions for the second virial coefficients of differently shaped hard solids of revolution in dependence on their aspect ratio. The second virial coefficients of convex hard solids, which are the orientational averages of the mutual excluded volume, are derived from volume, surface, and mean radii of curvature employing the Isihara-Hadwiger theorem. Virial coefficients of both prolate and oblate hard solids of revolution are investigated in dependence on their aspect ratio. The influence of one- and two-dimensional removable singularities of the surface curvature to the mutual excluded volume is analyzed. The virial coefficients of infinitely thin oblate and infinitely long prolate particles are compared, and analytical expressions for their ratios are derived. Beyond their dependence on the aspect ratio, the second virial coefficients are influenced by the detailed geometry of the particles.

  19. An Irish Revolution Without A Revolution

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available There is a conventional view among Irish historians that a revolution occurred in that country between the passing of the Third Home Rule Bill of 1912 and the end of the Civil War in 1923.  The violence of those years, the collapse in support for the Irish Parliamentary Party (IPP, the meteoric rise to power of Sinn Féin, a new sense of meritocracy, a greater sense of democracy and a widespread radicalism; all are seen as elements of a major change in Irish politics and life, a ‘Revolution.’  Drawing on Gramsci's notion of a “revolution without a revolution”, this paper seeks to understand the events in Ireland of 1912-23, not as a sudden rupture with the past but as the culmination of a much longer period of (often British-backed capitalist development in post-Famine Ireland. This paper argues that Irish nationalist politics in the decades before 1912 is better understood via categories such as class, gender, capitalism and the pervasive power of the British state.  As such, as well as pursuing a reassessment of the project of Irish historical development and state-building, this paper also seeks a reassessment of the project of (an equally statist Irish historiography.

    Full Text Available The article is devoted to an overview and analysis of Museum projects dedicated to the 100th anniversary of the Great Russian revolution. Preparing for the anniversary initiated a return to the difficult topic, the desire to relate modern historical knowledge of the Museum and of a concept of Russian history on the whole space of the country. The author selects two main groups of Museum projects with meta-and microhistory, which are disclosed through the regional aspects of the event, the individual aspects, the monologue of a single event or a single artifact, cultural theoretical reflection, personal understanding of our contemporaries.

  1. Analysis of thermal-plastic response of shells of revolution by numerical integration

    International Nuclear Information System (INIS)

    Leonard, J.W.

    1975-01-01

    An economic technique for the numerical analysis of the elasto-plastic behaviour of shells of revolution would be of considerable value in the nuclear reactor industry. A numerical method based on the numerical integration of the governing shell equations has been shown, for elastic cases, to be more efficient than the finite element method when applied to shells of revolution. In the numerical integration method, the governing differential equations of motion are converted into a set of initial-value problems. Each initial-value problem is integrated numerically between meridional boundary points and recombined so as to satisfy boundary conditions. For large-deflection elasto-plastic behaviour, the equations are nonlinear and, hence, are recombined in an iterative manner using the Newton-Raphson procedure. Suppression techniques are incorporated in order to eliminate extraneous solutions within the numerical integration procedure. The Reissner-Meissner shell theory for shells of revolution is adopted to account for large deflection and higher-order rotation effects. The computer modelling of the equations is quite general in that specific shell segment geometries, e.g. cylindrical, spherical, toroidal, conical segments, and any combinations thereof can be handled easily.

  2. Rings of non-spherical, axisymmetric bodies

    2018-01-01

    We investigate the dynamical behavior of rings around bodies whose shapes depart considerably from that of a sphere. To this end, we have developed a new self-gravitating discrete element N-body code, and employed a local simulation method to simulate a patch of the ring. The central body is modeled as a symmetric (oblate or prolate) ellipsoid, or defined through the characteristic frequencies (circular, vertical, epicyclic) that represent its gravitational field. Through our simulations we explore how a ring's behavior - characterized by dynamical properties like impact frequency, granular temperature, number density, vertical thickness and radial width - varies with the changing gravitational potential of the central body. We also contrast properties of rings about large central bodies (e.g. Saturn) with those of smaller ones (e.g. Chariklo). Finally, we investigate how the characteristic frequencies of a central body, restricted to being a solid of revolution with an equatorial plane of symmetry, affect the ring dynamics. The latter process may be employed to qualitatively understand the dynamics of rings about any symmetric solid of revolution.

    Ilya L. Morozov

    2017-12-01

    Full Text Available The article discusses the evolution of theories of social revolution from the mid-nineteenth to the late twentieth centuries. The author analyzes the basic concepts of theorists and practitioners of the armed revolutionary struggle – from the founder of the classical Communist theory of Karl Marx to the Mexican guerrilla leader Subcomandante Marcos. The author focuses on the analysis of changes in the understanding of the subject (“driving forces” of the left political revolution, as well as the strategy of armed revolutionary struggle. The author comes to the conclusion about the historical evolution of the subject of the revolutionary struggle from major sustainable macro-groups (“classes”, targeted at the armed struggle, to self-born (by the network principle unstructured protest groups, situational leaders, mild forms of the revolutionary struggle, which minimize the armed violence, though do not eliminate it completely. The author substantiates the conclusion about the absence in the modern protest movement of social forces, able to become the subject of revolution socialist orientation. This increases the danger of dominance of the social protest of extremist nationalist and religious political spectra. The author offers two models of response to this threat: the growing influence of the reigning centre-right conservative parties of Russia; return to center-left positions of the social democratic movement of the countries of the European Union.

The main argument presented here is that the attainment of freedom of the Internet and the success of the revolt created new opportunities for formal political involvement for the cyberactivists as they transited from dissidents under the Ben Ali regime to citizen-participants of a nascent democratic order. A subsidiary argument is that a new generation of Tunisian leadership came to the fore of Tunisia’s private and public spheres to advance the stated aims of the revolution, including inter alia combating unemployment, securing civil liberties, stemming corruption, and the ever deepening of pro-democracy reforms.

  16. When politics froze fashion: the effect of the Cultural Revolution on naming in Beijing.

    Science.gov (United States)

    Obukhova, Elena; Zuckerman, Ezra W; Zhang, Jiayin

    2014-09-01

    The authors examine the popularity of boys' given names in Beijing before and after the onset of the Cultural Revolution to clarify how exogenous and endogenous factors interact to shape fashion. Whereas recent work in the sociology of culture emphasizes the importance of endogenous processes in explaining fashion, their analysis demonstrates two ways in which politics shaped cultural expression during the Cultural Revolution: by promoting forms of expression reflecting prevailing political ideology and by limiting individuals' willingness to act differently. As argued by Lieberson and developed further in this article, the second condition is important because endogenous fashion cycles require a critical mass of individuals who seek to differentiate themselves from common practice. Exogenous factors can influence the operation of the endogenous factors. The authors discuss the implications of their study for understanding the nature of conformity under authoritarian regimes and social conditions supporting individual expression.

  17. [Big Data Revolution or Data Hubris? : On the Data Positivism of Molecular Biology].

    Science.gov (United States)

    Gramelsberger, Gabriele

    2017-12-01

    Genome data, the core of the 2008 proclaimed big data revolution in biology, are automatically generated and analyzed. The transition from the manual laboratory practice of electrophoresis sequencing to automated DNA-sequencing machines and software-based analysis programs was completed between 1982 and 1992. This transition facilitated the first data deluge, which was considerably increased by the second and third generation of DNA-sequencers during the 2000s. However, the strategies for evaluating sequence data were also transformed along with this transition. The paper explores both the computational strategies of automation, as well as the data evaluation culture connected with it, in order to provide a complete picture of the complexity of today's data generation and its intrinsic data positivism. This paper is thereby guided by the question, whether this data positivism is the basis of the big data revolution of molecular biology announced today, or it marks the beginning of its data hubris.

  20. A departure from cognitivism: Implications of Chomsky's second revolution in linguistics

    Science.gov (United States)

    Schoneberger, Ted

    2000-01-01

    In 1957 Noam Chomsky published Syntactic Structures, expressing views characterized as constituting a “revolution” in linguistics. Chomsky proposed that the proper subject matter of linguistics is not the utterances of speakers, but what speakers and listeners know. To that end, he theorized that what they know is a system of rules that underlie actual performance. This theory became known as transformational grammar. In subsequent versions of this theory, rules continued to play a dominant role. However, in 1980 Chomsky began a second revolution by proposing the elimination of rules in a new theory: the principles-and-parameters approach. Subsequent writings finalized the abandonment of rules. Given the centrality of rules to cognitivism, this paper argues that Chomsky's second revolution constitutes a departure from cognitivism.

    2010-12-01

    Full Text Available This article explores the question of the political meaning of the term “revolution” and the relation that has been established and should continue to be established between revolution and freedom. To this effect, the article examines some of the main proposals set forth in this respect by three contemporary thinkers, Hannah Arendt, Alain Badiou and Slavoj Žižek, with occasional references to Michel Foucault and Antonio Negri. The proposal argued for here is that Arendt’s notion of revolution and the notions of event and act put forth in the radical political theories of Badiou and Žižek intersect and necessarily supplement one another.

  3. Something fishy: Chile's blue revolution, commodity diseases, and the problem of sustainability.

    The United Nations describes aquaculture as the fastest-growing method of food production, and some industry boosters have heralded the coming of a sustainable blue revolution. This article interprets the meteoric rise and sudden collapse of Atlantic salmon aquaculture in southern Chile (1980-2010) by integrating concepts from commodity studies and comparative environmental history. I juxtapose salmon aquaculture to twentieth-century export banana production to reveal the similar dynamics that give rise to "commodity diseases"—events caused by the entanglement of biological, social, and political-economic processes that operate on local, regional, and transoceanic geographical scales. Unsurprisingly, the risks and burdens associated with commodity diseases are borne disproportionately by production workers and residents in localities where commodity disease events occur. Chile's blue revolution suggests that evaluating the sustainability of aquaculture in Latin America cannot be divorced from processes of accumulation.

  4. Preparing for the future: the implications of the information revolution for the Canadian nuclear industry

    The information revolution provides an opportunity for the Canadian nuclear industry to reinvigorate the information environment that supports companies and employees in achieving business and personal goals. Five necessary steps are to intensify the information environment; develop a new human resources model that stresses access to, and sharing of, information, and which comes to grips with the need for better programs to retrain and retain employees and to accommodate the 'mercenary' workforce; promote awareness of the information revolution; nurture individual initiatives; and develop an integrated approach called information engineering, which involves collaborative work between information technology, information management, and human resources. At the heart of all of these steps is the need for a new way of thinking about information and a determination to share information widely within our organisations and industry. Applying the recommended approaches within our industry will enable us to compete successfully in a global marketplace in which we are outnumbered and out gunned. (author)

    Full Text Available This article attempts to present some reflections about Rosa Luxemburg’sworks from the first Russian revolution (1905-1906. I consider Luxemburg’sview on the historical meaning of this revolution and discuss her analyses of classstruggle in 1905-1906. The description of class struggle’s forms and its dynamicsis the most important and interesting excerpt of Luxemburg’s works from this time.She emphasized the meaning of a revolutionary sense of freedom and the changingworkers consciousness that happens during the revolution. She presents an inspiringdialectic relation between defeated rebellion or revolution and the final victory ofsocialist movement. I think that Luxemburg’s perspective may be useful for researchon contemporary social struggles (e.g. “Arab Spring”, “Occupy!” and helpful insearching for new forms of organization for radical liberation movements.

    2015-01-01

    This report proposes an overview of LTO (Light Tight Oil or shale oil) production in the USA, and examines the consequences of oil price fall on its future level. The first part gives an assessment of five years of this revolution which follows the shale gas revolution. It addresses the most remarkable evolutions: spectacular development of production, decrease of oil imports, increase of oil product exports, and a move towards oil independence. The second part highlights some peculiarities of shale oils and of the resulting business model which is much different from the Exploration/Production model for conventional oil. It analyses the LTO economy and breakeven prices required for a continued investment. Technological advances which are at the basis of this revolution are addressed, and expected improvements on a short or medium term are described. The main financial indicators are then presented as the financial situation of LTO producers is a crucial factor for future investment levels. The last chapter reports the study of the impact of price decrease on capital expenditures (CAPEX) of American producers, and on the drilling activity. It seems that LTO production will resist to price decrease

    2015-01-01

    The purpose of this study was to evaluate the distribution of bubbles, degree of mixing, flowability and mechanical strength of powder-liquid reline material by manually and with a rotation-revolution (planetary) mixer, and to determine the usefulness of a rotation-revolution mixer for this application. Powder-liquid reline material (Mild Rebaron, GC, Tokyo, Japan) was mixed with a powder to liquid ratio of 1:0.62 according to the manufacturer's instruction. Two methods were used to mix it: mixed by manually ("manual-mixing") and automatically with a rotation-revolution mixer (Super Rakuneru Fine, GC, Tokyo, Japan; "automatic-mixing"). Disc-shaped specimens, 30 mm in diameter and 1.0mm in thickness, were used to observe the distribution of bubbles in at 10× magnifications. Flowability tests were carried out according to the JIS T6521 for denture base hard reline materials. A three point bending test was carried out by a universal testing machine. Elastic modulus and flexural stress at the proportional limit were calculated. A median of 4 bubbles and inhomogeneous were observed in manual-mixed specimens. However, no bubbles and homogeneous were observed in automatic-mixed specimens. Flowability was within the JIS range in all mixing conditions and did not differ significantly across conditions. The elastic modulus was the same for manual-mixed and automatic-mixed specimens. On the other hand, the flexural stress at the proportional limit differed significantly between manual-mixed and automatic-mixed specimens. The results confirm that rotation-revolution mixer is useful for mixing powder-liquid reline material. Automatic-mixing may be recommended for clinical practice.

    2011-01-01

    While the Green Revolution has been successful in some regions like South and East Asia, it could hardly address any achievement in Sub-Saharan Africa (SSA). This paper tries to draw a picture on lessons learned from the failures of this revolution that should be taken into account before implementing the so-called Gene Revolution in the SSA region. After scrutinizing the failures and the pros and cons of GM crops in the region, the paper introduces some potentials for improving the malnutrition situation in SSA through launching a successful GM technology. However, it remains doubtful whether this technology can improve the situation of small-scale farmers as long as they receive no financial support from their national governments. Therefore, before any intervention, the socio-economic and environmental impacts of GM technology need to be carefully addressed in the framework of a series of risk assessment studies. Besides, some sort of multi-stakeholder dialog (from small-scale farmers to consumers) involving public-private sector and non-governmental organizations should be heated up at both national and regional levels with regard to the myths and truths of this technology.

    Full Text Available The Ottoman and Spanish Empires struggled for the control of the Mediterranean throughout the entire 16th century. However, they preferred to re-set their political objectives and left the strugle for the Mediterranean in the late 16th century. The Ottomans and Spanish lost their political and military powers in the 17th and 18th centuries and they were challenged by the new great powers namely Britain, France and Russia. Spain managed to re-establish her diplomatic relations with the Ottomans by the Treaty of Peace and Trade in 1782. The Ottomans, on the other hand, saw this treaty as a document that contributed their security in the Mediterranean against the increasing Russian naval activities. The French Revolution, as the most important development in this period, effected social, economic, political and diplomatic life in Europe. Spain which followed anti-British policies, made an alliance with the revolutionary France. However, Napoleon's invasion of Egypt and the pro-French acts of the Spanish ambassador in Istanbul was an important breaking point in the Ottoman-Spanish relations. The French Revolution and Napoleon's invasion of Egypt caused a diplomatic battle between the pro-French and anti-French diplomats. This article aims to understand the effects of the French Revolution and the new balance of power on the Ottoman-Spanish relations.

    Full Text Available In this paper, Gergely Kunt analyzes the collaborative diary writing of two preadolescent boys from the period of the Hungarian Revolution of 1956, during which they decided to act as reporters and writers to create their own chronicles of the events transpiring between October 1956 and March 1957. Twelve-year-old Gyula Csics and thirteen-year-old János Kovács were close friends and neighbors in a tenement house in Budapest, which resulted in their collaborate project of writing and illustrating their own diaries in an attempt to record the events of the Hungarian Revolution. During this collaborative project, they would read and copy each other’s diaries, which primarily focused on public events, rather than the preadolescents’ private lives. In addition to their handwritten entries, the two boys illustrated their diaries with drawings that depicted street fights or damaged buildings, as well as newspaper clippings and pamphlets, which they had collected during and after the Revolution.

  15. Management of pediatric radiation dose using GE's Revolution digital radiography systems

    2004-01-01

    Digital flat-panel X-ray detectors offer excellent image quality and dose efficiency in addition to clinical productivity, connectivity, and adaptability to advanced clinical applications. GE's Revolution systems provide two modes of exposure control for setting the dose operating point, fixed time and automatic exposure control, the latter of which maintains high image signal-to-noise ratio for the given technique settings. In addition to enhancing detail contrast and compressing the dynamic range, postprocessing automatically determines the best window level and width for display, taking into account the dose at which the image was acquired. Several studies have examined the reduction in patient dose achievable with Revolution systems as compared to competing technologies, and results indicate significant dose savings with equivalent or superior image quality. For pediatric exams, pediatric default techniques provide for a lower patient dose as compared to adult techniques. Therefore, GE's Revolution systems can achieve a high image quality-to-dose ratio for pediatric imaging using the combined advantages of dose-efficient detection, advanced postprocessing, and independently adjustable pediatric techniques.

    We report a method for pulverizing poorly water soluble compounds with low melting points to nanoparticles without producing an amorphous phase using a rotation/revolution pulverizer. Fenofibrate, flurbiprofen, and probucol were used as crystalline model compounds. They were suspended in a methylcellulose aqueous solution and pulverized with zirconia balls by the rotation/revolution pulverizer. Beeswax, an amorphous compound, was also examined to investigate whether nano-pulverization of a compound with a low melting point was possible. Beeswax was suspended in ethyl alcohol cooled with liquid nitrogen and pulverized with zirconia balls by the rotation/revolution pulverizer. By optimizing the pulverization parameters, nanoparticles (D50 revolution speed of 1000 rpm and a rotation/revolution ratio of 1.0 when the vessel was 0 degrees C. Amorphous fenofibrate and flurbiprofen were not detected by differential scanning calorimetry or powder X-ray diffraction, whereas small amounts of amorphous probucol were detected. Beeswax was pulverized to nanoparticles (D50 = 0.14 microm) with ethyl alcohol cooled with liquid nitrogen. Fine nanoparticles of these poorly water soluble compounds with low melting points were obtained by controlling the rotation/revolution speed and reducing the vessel temperature.

    This survey aims to scrutinize important medical innovations in Chinese mainland since Xinhai (Hsin-hai) revolution in 1911, which marked the end of Manchurian imperial rule and the beginning of China's republican era. An online cross-sectional survey was carried out during the period of Dec 29, 2014 to Feb 5, 2015, totaling 37 days. The survey was conducted on the platform provided by DXY (www.dxy.cn), which is the largest medical and paramedical related website in China. An email was sent to all DXY registered users to invite them to participate in a 5-minute survey. The participants were asked to nominate up to four important medical innovations in China mainland since Xinhai revolution. The participant could select 'zero' which means he/she felt there was no important medical innovations, or he/she did not know important medical innovations. It was noted that important medical innovations refer to (I) those with practical and almost immediate significance to improve healthcare; (II) should not only be introducing western technique to China, but those involve major improvement of existing western techniques count; (III) should not be those with important theoretical discovery but did not have almost immediate significance to improve healthcare. In total 1,513 DXY users participated in the voting. Totally 489 (32.3%), 441 (29.1%), 342 (22.6%), 150 (9.9%), 91 (6.0%) participants provided 0, 1, 2, 3, 4 nominations respectively. (I) Artemisine (Qinghaosu) for malaria treatment (Project 523 team, 1972); (II) arsenic Trioxide (As2O3) for acute promyelocytic leukemia (APL) treatment (ZHANG Ting-Dong and colleagues, 1970s); (III) limb re-plantation (CHEN Zhong-Wei and colleagues, 1963); (IV) all-trans retinoic acid (ATRA) for APL treatment (WANG Zhen-Yi and colleagues, 1988); and (V) Wu's mask for plague prevention (WU Lien-The, 1910), were voted as the top five innovations in China mainland since Xinhai revolution, with 375, 96, 91, 53, and 8 votes respectively.

    The human body is the object upon which medicine is acting, but also lived reality, image, symbol, representation and the object of elaboration and theory. All these elements which constitute the body influence the way medicine is treating it. In this series of three articles, we address the human body from various perspectives: medical (1), phenomenological (2), psychosomatic and socio-anthropological (3). This first article discusses four distinct types of representation of the body within medicine, each related to a specific epistemology and shaping a distinct kind of clinical legitimacy: the body-object of anatomy, the body-machine of physiology, the cybernetic body of biology, the statistical body of epidemiology.

  1. Toward a microbial Neolithic revolution in buildings.

    Thaler, David S

    2016-03-29

    The Neolithic revolution--the transition of our species from hunter and gatherer to cultivator--began approximately 14,000 years ago and is essentially complete for macroscopic food. Humans remain largely pre-Neolithic in our relationship with microbes but starting with the gut we continue our hundred-year project of approaching the ability to assess and cultivate benign microbiomes in our bodies. Buildings are analogous to the body and it is time to ask what it means to cultivate benign microbiomes in our built environment. A critical distinction is that we have not found, or invented, niches in buildings where healthful microbial metabolism occurs and/or could be cultivated. Key events affecting the health and healthfulness of buildings such as a hurricane leading to a flood or a burst pipe occur only rarely and unpredictably. The cause may be transient but the effects can be long lasting and, e.g., for moisture damage, cumulative. Non-invasive "building tomography" could find moisture and "sentinel microbes" could record the integral of transient growth. "Seed" microbes are metabolically inert cells able to grow when conditions allow. All microbes and their residue present actinic molecules including immunological epitopes (molecular shapes). The fascinating hygiene and microbial biodiversity hypotheses propose that a healthy immune system requires exposure to a set of microbial epitopes that is rich in diversity. A particular conjecture is that measures of the richness of diversity derived from microbiome next-generation sequencing (NGS) can be mechanistically coupled to--rather than merely correlated with some measures of--human health. These hypotheses and conjectures inspire workers and funders but an alternative is also consequent to the first Neolithic revolution: That the genetic uniformity of contemporary foods may also decrease human exposure to molecular biodiversity in a heath-relevant manner. Understanding the consequences--including the unintended

    1986-01-01

    How unique and definitive is Euclidean geometry in describing the "real" space in which we live? Richard Trudeau confronts the fundamental question of truth and its representation through mathematical models in The Non-Euclidean Revolution. First, the author analyzes geometry in its historical and philosophical setting; second, he examines a revolution every bit as significant as the Copernican revolution in astronomy and the Darwinian revolution in biology; third, on the most speculative level, he questions the possibility of absolute knowledge of the world. Trudeau writes in a lively, entertaining, and highly accessible style. His book provides one of the most stimulating and personal presentations of a struggle with the nature of truth in mathematics and the physical world. A portion of the book won the Pólya Prize, a distinguished award from the Mathematical Association of America.

    2013-01-01

    The Earth that sustains us today was born out of a few remarkable, near-catastrophic revolutions, started by biological innovations and marked by global environmental consequences. The revolutions have certain features in common, such as an increase in the complexity, energy utilization, and information processing capabilities of life. This book describes these revolutions, showing the fundamental interdependence of the evolution of life and its non-living environment. We would not exist unless these upheavals had led eventually to 'successful' outcomes - meaning that after each one, at length, a new stable world emerged. The current planet-reshaping activities of our species may be the start of another great Earth system revolution, but there is no guarantee that this one will be successful. This book explains what a successful transition through it might look like, if we are wise enough to steer such a course. This book places humanity in context as part of the Earth system, using a new scientific synthe...

  6. The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions.

    Science.gov (United States)

    Portin, Petter

    2015-01-01

    The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

    2018-01-01

    Low-thrust trajectories about planetary bodies characteristically span a high count of orbital revolutions. Directing the thrust vector over many revolutions presents a challenging optimization problem for any conventional strategy. This paper demonstrates the tractability of low-thrust trajectory optimization about planetary bodies by applying a Sundman transformation to change the independent variable of the spacecraft equations of motion to an orbit angle and performing the optimization with differential dynamic programming. Fuel-optimal geocentric transfers are computed with the transfer duration extended up to 2000 revolutions. The flexibility of the approach to higher fidelity dynamics is shown with Earth's J 2 perturbation and lunar gravity included for a 500 revolution transfer.

  10. Thomas Kuhn's 'Structure of Scientific Revolutions' applied to exercise science paradigm shifts: example including the Central Governor Model.

    Pires, Flávio de Oliveira; de Oliveira Pires, Flávio

    2013-07-01

    According to Thomas Kuhn, the scientific progress of any discipline could be distinguished by a pre-paradigm phase, a normal science phase and a revolution phase. The science advances when a scientific revolution takes place after silent period of normal science and the scientific community moves ahead to a paradigm shift. I suggest there has been a recent change of course in the direction of the exercise science. According to the 'current paradigm', exercise would be probably limited by alterations in either central command or peripheral skeletal muscles, and fatigue would be developed in a task-dependent manner. Instead, the central governor model (GCM) has proposed that all forms of exercise are centrally-regulated, the central nervous system would calculate the metabolic cost required to complete a task in order to avoid catastrophic body failure. Some have criticized the CGM and supported the traditional interpretation, but recently the scientific community appears to have begun an intellectual trajectory to accept this theory. First, the increased number of citations of articles that have supported the CGM could indicate that the community has changed the focus. Second, relevant journals have devoted special editions to promote the debate on subjects challenged by the CGM. Finally, scientists from different fields have recognized mechanisms included in the CGM to understand the exercise limits. Given the importance of the scientific community in demarcating a Kuhnian paradigm shift, I suggest that these three aspects could indicate an increased acceptance of a centrally-regulated effort model, to understand the limits of exercise.

    Full Text Available Recent changes in medical education have highlighted the importance of experiential learning. Simulation is one model that has gained significant attention in the last decade and has been widely adopted as a training and assessment tool in medical education. Paediatric simulation has been utilized to teach various skills including resuscitation and trauma management, procedural skills and team training. It is also a valuable tool for health care educators, as it allows learners to achieve competence without putting patients at risk. Recent literature demonstrates increased retention of knowledge and skills after simulation based training. Further research is required to improve current simulation curriculums, develop validated assessment tools and to demonstrate improved clinical outcomes after simulation based training. We conducted an online search of original and review articles related to simulation and paediatric medical education and provide an overview of the role and utility of simulation in paediatrics.

  13. Analysis of thermal-plastic response of shells of revolution by numerical integration

    Leonard, J.W.

    1975-01-01

    A numerical method based instead on the numerical integration of the governing shell equations has been shown, for elastic cases, to be more efficient than the finite element method when applied to shells of revolution. In the numerical integration method, the governing differential equations of motions are converted into a set of initial-value problems. Each initial-value problem is integrated numerically between meridional boundary points and recombined so as to satisfy boundary conditions. For large-deflection elasto-plastic behavior, the equations are nonlinear and, hence, are recombined in an iterative manner using the Newton-Raphson procedure. Suppression techniques are incorporated in order to eliminate extraneous solutions within the numerical integration procedure. The Reissner-Meissner shell theory for shells of revolution is adopted to account for large deflection and higher-order rotation effects. The computer modelling of the equations is quite general in that specific shell segment geometries, e.g. cylindrical, spherical, toroidal, conical segments, and any combinations thereof can be handled easily. The elasto-plastic constitutive relations adopted are in accordance with currently recommended constitutive equations for inelastic design analysis of FFTF Components. The Von Mises yield criteria and associated flow rule is used and the kinematic hardening law is followed. Examples are considered in which stainless steels common to LMFBR application are used

Mandrou contribution to the study of the phenomenon of mentalities, and in particular the phenomenon of «mental» revolution is enormous. Thanks to him, the new French historiography changed its name to the historical psychology at the history of mentalities, and in interdisciplinary humanities studies of the Soviet period began to develop themes mentality.

    2006-09-01

    The industrialization and urbanization of Britain during the 19th century gave the medical profession something to think about. In particular, were the radical changes taking place in society responsible for the sudden rise in endemic and epidemic disease? This article (part of the Science in the Industrial Revolution series) examines the reactions of two key figures in the history of British public health, James Philips Kay and Thomas Southwood Smith, to this question. Their outlooks typify the tendency of Victorian medical practitioners to construct economies of health that saw disease as a consequence of the violation of natural laws and cycles rather than as a product of industrial modernity.

  16. Rethinking the Role of Grey Literature in the Fourth Industrial Revolution

    2018-01-01

    The world is at the dawn of a new industrial revolution that will fundamentally change the way we live and work. Many consider this the Fourth Industrial Revolution (4IR). While the First Industrial Revolution (1IR) mechanized production using water and steam power, the second one brought mass production using electric power, and the third one was characterized by automation and digitization, mainly using electronics and information technology. The 4IR is building upon the third one, but the difference, and its main contribution, is the fusion of technologies that are blurring the lines between the physical, digital, and biological worlds. This is further enhanced by the emerging progress of technology in fields such as quantum computing, machine learning, artificial intelligence, robotics, virtual assistants, the Internet of Things, self-driving cars, drones, 3-D printing, nanotechnology, biotechnology, traffic and security monitoring systems, and renewable energy. This paper examines the potential impact of the emerging 4IR on grey literature (GL) and is based on analysis of the most prevalent current trends and developments in “cyber-physical systems” that connect machines, computers and people. It will examine the need to rethink the definition of GL, its creation and publication types, processing, sustainability and usability. Given the magnitude of the potential impact of the 4IR on GL, the question is what challenges the 4IR will pose to GL managers. One could assume that the acquisition of new knowledge and skills, and the revamping of existing processes and methods will be necessary. Becoming aware of this new phenomenon is only the beginning. It needs to be followed up by professional development and adequate training. Finally, the job of GL professionals will be to promote and publicize the usefulness and importance of GL, not only in their daily work, but also in research and science. (author)

    Biomotors are extensively involved in biological processes including cell mitosis, bacterial binary fission, DNA replication, DNA repair, homologous recombination, Holliday junction resolution, RNA transcription, and viral genome packaging. Traditionally, they were classified into two categories including linear and rotation motors. In 2013, a third class of motor by revolution mechanism without rotation was discovered. In this issue of "Structure and mechanisms of nanomotors in the cells", four comprehensive reviews are published to address the latest advancements of the structure and motion mechanism of a variety of biomotors in archaea, animal viruses, bacteria, and bacteriophages.

    The Cambrian radiation of complex animals includes a dramatic increase in the depth and intensity of bioturbation in seafloor sediment known as the 'agronomic revolution'. This bioturbation transition was coupled with a shift in dominant trace fossil style from horizontal surficial traces in the late Precambrian to vertically penetrative trace fossils in the Cambrian. Here we show the existence of the first vertically penetrative trace fossils from the latest Ediacaran: dense occurrences of the U-shaped trace fossil Arenicolites from late Precambrian marine carbonates of Western Mongolia. Their Ediacaran age is established through stable carbon isotope chemostratigraphy and their occurrence stratigraphically below the first appearance of the trace fossil Treptichnus pedum . These Arenicolites are large in diameter, penetrate down to at least 4 cm into the sediment, and were presumably formed by the activity of bilaterian animals. They are preserved commonly as paired circular openings on bedding planes with maximum diameters ranging up to almost 1 cm, and as U- and J-shaped tubes in vertical sections of beds. Discovery of these complex penetrative trace fossils demonstrates that the agronomic revolution started earlier than previously considered.

    In Portugal, Spain, and South Africa, there has been a noted anti-neoliberal resistance, marked by the significant participation of the older generation in protest movements. Changing demographics, the global financial crisis, unemployment, poverty, and the reliance of the family nucleus on the pensioner, coupled with neoliberal and austerity-based reductions to welfare programs, pensions, health, and social care, has caused the "silver revolution." As a population group that is often considered to be less politically active and robust members of society, such resistance is a noteworthy moment in society that needs to be considered and responded to.

  8. Number of revolutions of a particle around a black hole: Is it infinite or finite?

    Science.gov (United States)

    Pavlov, Yuri V.; Zaslavskii, Oleg B.

    2018-01-01

    We consider a particle falling into a rotating black hole. Such a particle makes an infinite number of revolutions n from the viewpoint of a remote observer who uses the Boyer-Lindquist type of coordinates. We examine the behavior of n when it is measured with respect to a local reference frame that also rotates due to dragging effect of spacetime. The crucial point consists here in the observation that for a nonextremal black hole, the leading contributions to n from a particle itself and the reference frame have the same form being in fact universal, so that divergences mutually cancel. As a result, the relative number of revolutions turns out to be finite. For the extremal black hole this is not so, n can be infinite. Different choices of the local reference frame are considered, the results turn out to be the same qualitatively. For illustration, we discuss two explicit examples—rotation in the flat spacetime and in the Kerr metric.

    Science.gov (United States)

    2014-01-01

    There is no question about the negative effects of child sexual abuse. Freud's seduction theory asserts that psychoneuroses in adults are caused by reactivation of forgotten recollections of gross sexual abuse (involving the genitals) that had taken place prior to the age of 8 to 10 years. His contribution consisted in the discovery of specific events, prior to puberty, which were indispensable to the formation of psychoneuroses. If an adult patient recalled an infantile sexual experience, Freud assumed the interference of a pervert: a child was sexually innocent unless it had been traumatized. But Freud's technique of clinical exploration had not attained adequate reliability and was not immune to prejudices. Freud himself dropped his mechanical, static theory that presupposed a single type of accidentally occurring trauma prior to puberty, allowing him to develop his new drive and fantasy theory.

    Directory of Open Access Journals (Sweden)

    Francesca Borruso

    2015-01-01

    Full Text Available The essay analyzes how the parent-children relationship changed within the bourgeois family between the Eighteen and the Nineteen centuries, also with a look to gender differences. The birth of the love marriage, the transformation of the parent-child relationship towards a more intimate and equal affective relationship, the transformation of the education style, the nineteenth-century cult of motherhood are some of the topics analyzed, that are deemed essential for understanding the complex transformations of family relationships in the western society. Jean-Jacques Rousseau is one of the first representatives of these changes of mentality. The radical critique of the family initiated by Rousseau, in fact, opens the way to a slow shift towards a democratic conception of the relationship between parents and children. The new model of family proposed by Rousseau – notwithstanding the male superiority in terms of «natural law» – is grounded on the agreement and mutual support between the spouses. Finally, the analysis of certain family stories – Manzoni and Rosselli – offers a micro-historical glance to family relationships during the Nineteenth and Twentieth centuries. The sources relate not only to the educational literature but also to novels on education, i.e. those non-official narratives (diaries, epistolaries, literary sources that can explain the educational experiences and the network of social and educational conditionings individual lives Cómo referenciar este artículo / How to reference this article Borruso, F.

  10. Timely Revolutions: On the Timelessness of the Unconscious

    Directory of Open Access Journals (Sweden)

    Fanny Söderbäck

    2014-12-01

    Full Text Available Julia Kristeva’s work on the concept of revolt is marked by a temporal analysis that takes revolt to be a movement of return into the past that makes possible change, rebirth, and an open future. Such temporal revolt is, according to Kristeva, intimate, in that it touches on unconscious psychic structures and operates on the level of thought and creativity. But Kristeva simultaneously inherits Freud’s notion that the unconscious is timeless. How, I ask, can revolt be defined as a temporal movement of return while at the same time being rooted in timelessness? I examine both Freud’s and Kristeva’s discussions of the timelessness of the unconscious and suggest that it needs to be understood not as non-temporal or outside of time, but rather as a temporal structure that challenges traditional philosophical conceptions of time. As such, the timelessness of the unconscious is far from being yet another instantiation of metaphysical presence. Rather, I see it as offering a challenge to both metaphysical presence and linear time, and indeed as making possible the retrospective movement of return that revolt for Kristeva must be.

    To realize the sustainable development of China’s energy industry, it is necessary to speed up the transformation of energy development mode and deepen the reform of the energy system in an all-round way so as to establish a clean, low-carbon, safe and efficient modern energy system. This paper analysed the opportunities and challenges in energy sectors to promote the energy mix update in China. Fossil energy, especially coal, has brought great progress to the world as well as a great deal of negative effects. In recent years, China’s greenhouse gas emissions continued to grow rapidly, and has become the world’s largest greenhouse gas emitter. To deal with the challenge, the Chinese government has promised that renewable energy will account for 15% of total energy consumption in 2020 and 20% in 2030. This goal requires China to add 800 to 1000 GW of wind, solar and other clean energy.

    Full Text Available In this article I attempt to analyze the social memories of wives of soldiers in service on April 25th 1974, through the methodology of analysis recommended by Adele Clarke (2005, using data collected in 11 interviews conducted between 2005 and 2008 under a PhD project. As a conceptual framework I adopt the perspective of social memory in the tradition of Halbwachs (1992 and following Marc Augé (2001 and Paul Ricoeur (2004, which emphasizes the social and collective memory and points out the dynamic role it plays in building a meaning to the world. This analysis takes into account the dimensions of work, family, education, politics and social life, social and economic conditions and the expectations and dreams on which the interviewees draw comparisons between 1974 and the present and also produce judgments.

    The biopuces of DNA analysis is an ambitious project. In ten years, the biopuces will be the main tools for medicine, especially in diagnosis. The DNA hybridization consists to combine DNA sequences of a sample with specific synthesized complementary DNA sequences, called DNA probes, which are easily detectable. It permits to have information about the presence of the selected DNA sequence in the Sample. On a biopuce, this operation is achieved by grafting the corresponding probes to a common support (F.M.)

  5. The quiet revolution. Child survival comes of age.

    Science.gov (United States)

    Bendahmane, D B

    1994-01-01

    Programs to reduce infant and child mortality have led to improvements in most countries of the world, developed and developing alike. These improvements can be seen graphically on maps produced by the USAID Child Survival Program which was launched in 1985 and which provided a "package" of health interventions that has led to a 10% mortality decline. These interventions have led to an increase in life expectancy in developing countries from 50 years in 1965 to over 60 years in 1986. Unfortunately, the children whose lives have been saved face a cruel paradox because their prospects for improving their lives are slim. They are the victims of deepening poverty, the stresses of urban life, and war and violence. In addition, the education which could allow them to escape their fate is largely denied to them. Although 90% of the children in developing countries enter school, an estimated 100 million drop out before grade 5. To make matters worse, most of the child survivors live in countries where the young age of the majority of the citizens is straining government resources. Even young people in the developed world are not immune from these problems; in the US, children are worse off than they were 25 years ago. While the struggle to increase child survival must continue, the world must also nurture the children who survive. The vicious cycle of population growth, poverty, and environmental degradation (PPE), which causes and is exacerbated by political and social instability, has been weakened by child survival programs which have reduced fertility rates. Education, especially of girls, also has a positive effect on the spiral. The effects of education, health and nutrition, and family planning programs can create a "virtuous" cycle which can increase gross domestic income and equity of income distribution (resulting in shared growth and "human capital accumulation"). Such initiatives as innovative community youth programs and new financing mechanisms can have a

  6. Pros and cons of the revolution in radiation protection

    International Nuclear Information System (INIS)

    Latek, Stanislav

    2001-01-01

    In 1959, the International Commission of Radiation Protection (ICRP) chose the LNT (Linear No-Threshold) model as an assumption to form the basis for regulating radiation protection. During the 1999 UNSCEAR session, held in April in Vienna, the linear no-threshold (LNT) hypothesis was discussed. Among other LNT-related subjects, the Committee discussed the problem of collective dose and dose commitment. These concepts have been introduced in the early 1960s, as the offspring of the linear no-threshold assumption. At the time they reflected a deep concern about the induction of hereditary effects by nuclear tests fallout. Almost four decades later, collective dose and dose commitment are still widely used, although by now both the concepts and the concern should have faded into oblivion. It seems that the principles and concepts of radiation protection have gone astray and have led to exceedingly prohibitive standards and impractical recommendations. Revision of these principles and concepts is now being proposed by an increasing number of scientists and several organisations

  7. Revolution in the provision of dental services in the UK.

    Science.gov (United States)

    Tickle, Martin

    2012-10-01

    The National Health Service (NHS) in England provides a comprehensive dental service funded largely from taxation but supplemented by co-payments. This paper provides a historical overview of NHS dental services and some personal reflections on the main challenges over the next five years. A narrative review of the literature and some subjective observations and comments. In 2006 there was a radical change to NHS dental services in England; central budgets were capped and general dental practitioners. Dentists who were previously paid on a fee-for-item basis moved to a new contract that required them to hit activity targets to maintain their historical income. This contract was unpopular with dentists and has been criticized for not improving access or quality. A new dental contract has been promised based on capitation. Against this background significant issues have to be addressed including: a rapidly growing gap in between demand and resources and a need to make substantial cost savings across the whole of the NHS; a significant decline in dental need; inequalities in utilisation of dental services; and provision of treatments of doubtful effectiveness. The NHS dental healthcare system faces significant challenges and consideration needs to be given to the consequences of a focus on need rather than demand. Logically this would require a needs-based resource allocation formula and a needs-based approach to service and workforce planning. A move to a needs-led service is a political decision with associated political risks. © 2012 John Wiley & Sons A/S.

  8. Oligosaccharide biotechnology: an approach of prebiotic revolution on the industry.

    Oligosaccharides are polymers with two to ten monosaccharide residues which have sweetener functions and sensory characteristics, in addition to exerting physiological effects on human health. The ones called nondigestible exhibit a prebiotic behavior being fermented by colonic microflora or stimulating the growth of beneficial bacteria, playing roles in the immune system, protecting against cancer, and preventing cardiovascular and metabolic issues. The global prebiotics market is expected to grow around 12.7% in the next 8 years, so manufacturers are developing new alternatives to obtain sustainable and efficient processes for application on a large scale. Most studied examples of biotechnological processes involve the development of new strategies for fructooligosaccharide, galactooligosaccharide, xylooligosaccharide, and mannanooligosaccharide synthesis. Among these, the use of whole cells in fermentation, synthesis of microbial enzymes (β-fructofuranosidases, β-galactosidases, xylanases, and β-mannanases), and enzymatic process development (permeabilization, immobilization, gene expression) can be highlighted, especially if the production costs are reduced by the use of agro-industrial residues or by-products such as molasses, milk whey, cotton stalks, corncobs, wheat straw, poplar wood, sugarcane bagasse, and copra meal. This review comprises recent studies to demonstrate the potential for biotechnological production of oligosaccharides, and also aspects that need more investigation for future applications in a large scale.

    In the digital times, digital technology has penetrated into every industry. As the highest safety requirement standard, nuclear power industry needs digital technology more to breed high quality and efficiency. Digital power plant is derived from digital design and the digitisation of power plant transfer is an inevitable trend. This paper introduces the technical solutions and features of digital nuclear power plant construction by Shanghai Nuclear Engineering Research & Design Institute, points out the key points and technical difficulties that exist in the process of construction and can serve as references for further promoting construction of digital nuclear power plant. Digital technology is still flourishing. Although many problems will be encountered in construction, it is believed that digital technology will make nuclear power industry more safe, cost-effective and efficient. (author)

    Full Text Available This article analyzes the news reports written by the Portuguese novelist and journalist Eça de Queirós about the crisis in 1881-1882 that resulted in the bombing of Alexandria, Egypt, by a British fleet. First, following Barbie Zelizer, we examine the communication of this historical event by analyzing how the news reports covering the event were written, taking into account the literary form commonly used during the period. For Zelizer, figures could not be trusted, and the plot and storyline were preferable. Second, as proposed by Hallin and Mancini, we analyze media practices during the period and compare the practices of the British and Luso-Brazilian print media. Eça appropriated information broadcasts by British journalists and reformulated them for his readers, emphasizing the key issues that lurked beneath the events of 1881-1882. Third, we analyze how the Egyptian army and Colonel Arabi went from being demonized to a position of heroes in modern Egypt through reports by the Brazilian periodical Gazeta de Noticias that were published in 1882 in Rio de Janeiro and were considered the culmination of its journalistic activities.

  16. Conceptual Modeling in the Time of the Revolution: Part II

    Science.gov (United States)

    Mylopoulos, John

    Conceptual Modeling was a marginal research topic at the very fringes of Computer Science in the 60s and 70s, when the discipline was dominated by topics focusing on programs, systems and hardware architectures. Over the years, however, the field has moved to centre stage and has come to claim a central role both in Computer Science research and practice in diverse areas, such as Software Engineering, Databases, Information Systems, the Semantic Web, Business Process Management, Service-Oriented Computing, Multi-Agent Systems, Knowledge Management, and more. The transformation was greatly aided by the adoption of standards in modeling languages (e.g., UML), and model-based methodologies (e.g., Model-Driven Architectures) by the Object Management Group (OMG) and other standards organizations. We briefly review the history of the field over the past 40 years, focusing on the evolution of key ideas. We then note some open challenges and report on-going research, covering topics such as the representation of variability in conceptual models, capturing model intentions, and models of laws.

    Full Text Available Jewish observance of shmita (alternatively spelled shemitah—the sabbatical year, or seventh (sheviit year—is changing. Historically rooted in agriculture, modern Jewish environmentalists are seizing upon the long-ignored environmental and social justice (tikkun olam aspects of shmita as originally described in the five books of Moses, the Torah in the Hebrew Bible, the basis of Jewish law. Primary research was conducted through key-stakeholder interviews with leading American and Israeli Jewish environmentalists and thought leaders. They see shmita as a core Jewish value—one that, like Shabbat, the Jewish sabbath, has the power to transform society. Their work has brought shmita from an obscure law dealt with mainly by Israel’s Orthodox to a new Jewish ethos being discussed across the United States, Europe, Israel, and even on the floor of Knesset, Israel’s parliament. This article also describes shmita as delineated in the Torah and through the rabbinic canon of halacha (Jewish law, and explains shmita practice from biblical times to the present day.

    2014-04-01

    Electronic cigarettes (e-cigarettes) have been increasingly available and marketed in the U.S. since 2007. As patterns of product adoption are frequently driven and reinforced by marketing, it is important to understand the marketing claims encountered by consumers. To describe the main advertising claims made on branded e-cigarette retail websites. Websites were retrieved from two major search engines in 2011 using iterative searches with the following terms: electronic cigarette, e-cigarette, e-cig, and personal vaporizer. Fifty-nine websites met inclusion criteria, and 13 marketing claims were coded for main marketing messages in 2012. Ninety-five percent of the websites made explicit or implicit health-related claims, 64% had a smoking cessation-related claim, 22% featured doctors, and 76% claimed that the product does not produce secondhand smoke. Comparisons to cigarettes included claims that e-cigarettes were cleaner (95%) and cheaper (93%). Eighty-eight percent stated that the product could be smoked anywhere and 71% mentioned using the product to circumvent clean air policies. Candy, fruit, and coffee flavors were offered on most sites. Youthful appeals included images or claims of modernity (73%); increased social status (44%); enhanced social activity (32%); romance (31%); and use by celebrities (22%). Health claims and smoking-cessation messages that are unsupported by current scientific evidence are frequently used to sell e-cigarettes. Implied and overt health claims, the presence of doctors on websites, celebrity endorsements, and the use of characterizing flavors should be prohibited.

  2. Sawah Rice Eco-technology and Actualization of Green Revolution in West Africa: Experience from Nigeria and Ghana

    Directory of Open Access Journals (Sweden)

    O.I. OLADELE

    2010-09-01

    Full Text Available The development and dissemination of sawah rice eco-technology in Nigeria and Ghana as prerequisites for the actualization of green revolution in West Africa were described. It showed that the neglect of the eco-technology and the overemphasis of the biotechnology have rendered the ineffective transferability of the green revolution process from Asia to Africa. The sawah eco-technology increases yield up to 5 t/hm2 through bunding and the use of inlet and outlet connecting irrigation and drainage, which enhances effective water control and management, improves the efficiency of fertilizer, improves nitrogen fixation by soil microbes and algae, increases the use of wetlands, improves soil organic matter accumulation, suppresses weed growth, and enhances immune mechanism of rice through nutrient supply. The current experience has therefore established that the technology overcomes the constraints that have limited the realization of green revolution in West Africa.

  6. The lemur revolution starts now: the genomic coming of age for a non-model organism.

    Science.gov (United States)

    Yoder, Anne D

    2013-02-01

    Morris Goodman was a revolutionary. Together with a mere handful of like-minded scientists, Morris established himself as a leader in the molecular phylogenetic revolution of the 1960s. The effects of this revolution are most evident in this journal, which he founded in 1992. Happily for lemur biologists, one of Morris Goodman's primary interests was in reconstructing the phylogeny of the primates, including the tooth-combed Lorisifomes of Africa and Asia, and the Lemuriformes of Madagascar (collectively referred to as the suborder Strepsirrhini). This paper traces the development of molecular phylogenetic and evolutionary genetic trends and methods over the 50-year expanse of Morris Goodman's career, particularly as they apply to our understanding of lemuriform phylogeny, biogeography, and biology. Notably, this perspective reveals that the lemuriform genome is sufficiently rich in phylogenetic signal such that the very earliest molecular phylogenetic studies - many of which were conducted by Goodman himself - have been validated by contemporary studies that have exploited advanced computational methods applied to phylogenomic scale data; studies that were beyond imagining in the earliest days of phylogeny reconstruction. Nonetheless, the frontier still beckons. New technologies for gathering and analyzing genomic data will allow investigators to build upon what can now be considered a nearly-known phylogeny of the Lemuriformes in order to ask innovative questions about the evolutionary mechanisms that generate and maintain the extraordinary breadth and depth of biological diversity within this remarkable clade of primates.

    Massive amounts of anthropogenic radionuclides were released from the nuclear reactors located in Fukushima (northeastern Japan) between 12 and 16 March 2011 following the earthquake and tsunami. Ground level air radioactivity was monitored around the globe immediately after the Fukushima accident. This global effort provided a unique opportunity to trace the surface air mass movement at different sites in the Northern Hemisphere. Based on surface air radioactivity measurements around the globe and the air mass backward trajectory analysis of the Fukushima radioactive plume at various places in the Northern Hemisphere by employing the Hybrid Single-Particle Lagrangian Integrated Trajectory model, we show for the first time, that the uninterrupted complete revolution of the mid-latitude Surface Westerlies took place in less than 21 days, with an average zonal velocity of > 60 km/h. The position and circulation time scale of Surface Westerlies are of wide interest to a large number of global researchers including meteorologists, atmospheric researchers and global climate modellers. -- Highlights: ► Evidence of the South Korea contamination with released radiocesium from Fukushima. ► Field samples and air mass analysis were utilized to elucidate the transport of those radionuclides. ► Characterization of the air mass movements at different sites at the Earth's surface. ► Verification of the uninterrupted complete revolution of the artificial radionuclides released in Fukushima. ► Quantification of the velocity of the artificial radionuclides released in Fukushima.

  8. EDUCATION, CLASS STRUGGLE, REVOLUTION. SUBJECTIVITY AND OBJECTIVITY IN THE THEORY OF KARL MARX

    Directory of Open Access Journals (Sweden)

    Irene Viparelli

    2011-02-01

    Full Text Available This article aims to investigate the relationship between education, class struggle and revolution based on Manifesto and the "historical texts" of Marx on the 1848 revolution. Initially, some confrontation will be shown fruitful by illuminating the basic features of the theoretical Marxian: rejecting both "objectivist" and "subjectivist" interpretations. Marx’s theory of history turns out to be founded on two different times - linear and cyclical. These define a dialectical relationship between objectivity and subjectivity of history. Next, the same confrontation will be used to show that Marx represents the process in which the proletariat acquires a mature revolutionary consciousness. Far from considering it as "simple" development of proletarian class consciousness, Marx conceives this process as a more complex path, thus, it is implicated in all social classes. Finally, the last part is devoted to showing "empirically" this theoretical device in action: through the analysis of Marx on the development of class struggles in France, it will "almost" show the absolute centrality of the educational dimension in Marxist conception of history

    Full Text Available After 1979 Islamic revolution, from April 20 to 22, 1980 universities in Tehran, Tabriz and some other cities, experienced an outstanding political juncture. Active collegiate political groups were compelled to surrender their rooms and offices, and leave the universities’ campus. Accordingly, universities and cities were the scene of bloody clashes. As a matter of fact, university as the fortress of freedom, resistance and revolution against Pahlavi was about to change its revolutionary identity and to adapt new role of an engaged proponent of Islamic regime. Concerning to Badiou’s concept of empty space and Delousian Rhizomatic analysis, we study related news and pictures of related newspapers. Concludingly, we demonstrate the set of relations in which Islamic university renovates. Also, we illustrate how the universities, on the one hand, acted as an agent and a mechanism for de-centering the revolutionary characteristic, and remaining this “Holy Place”, in Ayatollah Khomeini’s word, as a permanent Islamic partisan of new born political regime, simultanouly.

  10. The geopolitical impact of the shale revolution: Exploring consequences on energy prices and rentier states

    2016-01-01

    While the shale revolution was largely a US’ affair, it affects the global energy system. In this paper, we look at the effects of this spectacular increase in natural gas, and oil, extraction capacity can have on the mix of primary energy sources, on energy prices, and through that on internal political stability of rentier states. We use two exploratory simulation models to investigate the consequences of the combination of both complexity and uncertainty in relation to the global energy system and state stability. Our simulations show that shale developments could be seen as part of a long term hog-cycle, with a short term drop in oil prices if unconventional supply substitutes demand for oil. These lower oil prices may lead to instability in rentier states neighbouring the EU, especially when dependence on oil and gas income is high, youth bulges are present, or buffers like sovereign wealth funds are too limited to bridge the negative economic effects of temporary low oil prices. - Highlights: • We quantitatively explore geopolitical consequences of the shale gas revolution. • We use a multi-model approach to generate and use energy price scenarios. • Simulations show that current low oil prices could be part of a hog cycle. • The shale gas boom was an early warning for the drop in oil prices. • Low prices due to shale gas can reduce internal stability in rentier states.

    Full Text Available The article considers the problem of increasing the technological competitiveness of Ukrainian enterprises under conditions of a new industrial revolution through the development and introduction of advanced converged technologies. The classification of industrial revolutions, namely, industrial, technological, information and Industry 4.0, is presented, and it has been determined that the key factor of the latter is cyber physical systems for introduction of the client-oriented “Internet of Things”. It has been justified that the formation of Industry 4.0 in developed countries will occur through advanced production technologies (APT, which main characteristics are technological substitution, automation, customization, localization and economic efficiency. It has been found that in 2020 the main priority APT will be: systems of production process control; multidimensional modeling of complex products; intelligent production systems and robotics; systems of creation and transformation (growing of material objects and 3D-printing; materials effective in creating perspective actuating devices (compositional and those that exhibit their properties in small-size structures. It has been proved that the recovery of Ukraine’s industry is not possible on the old industrial base, and the creation of a new industry based on APT of Industry 4.0 is possible in the following areas: ICT (primarily in the field of software development; new composite materials with specified properties; industrial nanobiotechnologies (biomedicine and pharmacy, new agricultural technologies; mathematical modeling for creation of intelligent production systems; space research and development (in particular, development of the first stages of heavy missiles. The necessity of elaborating state programs of competitiveness development on the basis of APT, foresight research oftechnology priorities, promoting high-tech exports in Ukraine has been substantiated.

    Full Text Available This article takes a discourse analytical approach to elements of the 40th commemoration of the Portuguese Revolution, focusing specifically on the absence of themes and participants by groups who were most directly involved in the Revolution, either as actors (the “Captains of Abril”, the retornados (Portuguese nationals “returning” to Portugal in the aftermath of the 1974 coup and retornados-emigrantes (those who left Africa during this period but went on to live outside Portugal.   The analyses center primarily on the speech by Portuguese President Cavaco Silva, given as the official opening of the 40th anniversary of the military coup of 25 April 1974, which brought the authoritarian regime of 48 years to an end.  This examination, combined with other speeches of Cavaco Silva, newspaper reports, analyses of the integration of retornados, and a commemorative TV miniseries on the Revolution, provide the evidence for the argument that important voices of the Revolution were muted or silenced in the official commemoration of 2014. Finally, the relevance of actor-centered perspectives on commemoration is laid out for educators.

  14. Continental Contemporary Readings of the English Revolution. The Cases of Italy and Spain as Examples

    Directory of Open Access Journals (Sweden)

    Ángel ALLOZA APARICIO

    2014-02-01

    Full Text Available Initiated at the very beginning of the movements, discussions about the origin and causes of the English revolution have become one of the most valuable themes within the Anglo-Saxon historiography. On the contrary, continental contemporary readings of those events remain to be decoded and fully comprehended. This article reveals and examines some of those readings, notably those registered in Italian republics and in Spain, including some of them which have remained so far out of the scope of the historian. Despite the common features apprehended among the cases studied, all of them show a wide range of interpretations; variety which derives from the different forms of approaching to the past, from the degree of pragmatism of the reports analysed, and from the ideological and cultural positioning of their authors.

  15. Optimal design of geometrically nonlinear shells of revolution with using the mixed finite element method

    Science.gov (United States)

    Stupishin, L. U.; Nikitin, K. E.; Kolesnikov, A. G.

    2018-02-01

    The article is concerned with a methodology of optimal design of geometrically nonlinear (flexible) shells of revolution of minimum weight with strength, stability and strain constraints. The problem of optimal design with constraints is reduced to the problem of unconstrained minimization using the penalty functions method. Stress-strain state of shell is determined within the geometrically nonlinear deformation theory. A special feature of the methodology is the use of a mixed finite-element formulation based on the Galerkin method. Test problems for determining the optimal form and thickness distribution of a shell of minimum weight are considered. The validity of the results obtained using the developed methodology is analyzed, and the efficiency of various optimization algorithms is compared to solve the set problem. The developed methodology has demonstrated the possibility and accuracy of finding the optimal solution.

    Directory of Open Access Journals (Sweden)

    María Eugenia Rabadán Villalpando

    2017-07-01

    Full Text Available This article offers some solutions to problems relating to the theory and methodology of a particular piece of research into modern and contemporary landscaping. It concerns the dynamic processes of theoretical, epistemological and formal changes in the visual arts in the 20th and 21st centuries. The analysis, based on the structuralism of scientific revolutions first published by Thomas Kuhn, offers some answers to the debate on the articulation of paradigms in the history of science, according to Kuhn, instead of the articulation of styles in art history, according to Heinrich Wölfflin, Meyer Shapiro and Ernst Gombrich, among others, considering science and art as entities of a different nature. Kuhn’s approach to art history, particularly to the work of Gombrich, leads us to draw a parallel between science and art in Kuhn’s work, where he attempted to articulate paradigms in art history.

  19. Inertia Effects in the Flow of a Herschel-Bulkley ERF between Fixed Surfaces of Revolution

    Directory of Open Access Journals (Sweden)

    A. Walicka

    2013-01-01

    Full Text Available Many electrorheological fluids (ERFs as fluids with microstructure demonstrate viscoplastic behaviours. Rheometric measurements indicate that some flows of these fluids may be modelled as the flows of a Herschel-Bulkley fluid. In this paper, the flow of a Herschel-Bulkley ER fluid—with a fractional power-law exponent—in a narrow clearance between two fixed surfaces of revolution with common axis of symmetry is considered. The flow is externally pressurized, and it is considered with inertia effect. In order to solve this problem, the boundary layer equations are used. The influence of inertia forces on the pressure distribution is examined by using the method of averaged inertia terms of the momentum equation. Numerical examples of externally pressurized ERFs flows in the clearance between parallel disks and concentric spherical surfaces are presented.

  20. Elasto/visco-plastic analysis of moderately thick shells of revolution

    International Nuclear Information System (INIS)

    Takezono, S.; Tanoue, M.

    1981-01-01

    The analytical formulation on the elasto-visco-plastic problems of general, moderately thick shells of revolution subjected to axisymmetrical load is developed by extension of the Reissner theory in elastic shells where a consideration on the effect of shear deformations is given. The authors employ as constitutive relation of the shell materials Perzyna's equation where in the plastic range the viscosity of the material is considered. The criterion for yielding used in this analysis is the von Mises yield theory. The basic differential equations derived for elasto-visco-plastic problems are numerically solved by a finite difference method, and the solutions are obtained by integration of the incremental values. As a numerical example, the elasto/visco-plastic deformation of pressure vessels is analyzed, and the results are compared with those from the classical theory which neglects the effect of shear deformations.

    Adelman, Jeremy

    2018-01-01

    This essay examines the ways in which the age of revolutions expanded the repertoire of political ideas and identities available to new and old political subjects. It questions the traditional narrative that replaces a model of old regimes and empires with a new one of imagined unitary nation-states. Instead, it argues that the nature of the political crisis of the Iberian empires gave rise to a reinvention of familiar categories, like monarchy and empire, and sired a wider range of new ones that did not fit the national mold.

  4. Elasto/visco-plastic analysis of moderately thick shells of revolution under asymmetrical loading

    International Nuclear Information System (INIS)

    Tao, K.; Takezono, S.

    1987-01-01

    In the present paper the analytical formulation for the elasto/visco-plastic problems of general, moderately thick shells of revolution subjected to asymmetrical loads is developed in consideration of the effect of shear deformation. The equations of equilibrium and the relations between the strains and displacements are derived by extending the Reissner-Naghdi theory (1941, 1957) for elastic shells with given consideration to the effect of shear deformation. As the constitutive relation, Hooke's law is used in the liner elastic range, and the elasto/visco-plastic equations by Perzyna (1966) are employed in the plastic range. The fundamental equations on the elasto/visco-plastic problems derived for incremental values are numerically solved by a finite difference method and the solutions are obtained by summation of the incremental values.

    International Nuclear Information System (INIS)

    Kueny, L.; Levesque, J.

    2017-01-01

    The on-going digital revolution implies the sharing of data beyond the company walls, the development of connected objects and the setting of more and more complex digital networks. All of this increases the risk of being attacked by cyber-criminal and the probability is all the higher because new kinds of cyber-attacks appear every year. Originally nuclear industry has a culture of safety and has implemented numerous mechanisms of physical protection that slow down cyber-attacks. The humane factor is very often an important point for the success of a cyber-attack but the automation of repetitive tasks can reduce this risk. A cyber-attack can stay undetected if regularly overhauls of computer systems are not performed or if they are not adequately monitored. The reliability of digital tools for instance digital archives is a point that hinders the implementation of a total digital certification in the nuclear industry. (A.C.)

    The endemic of chronic renal failure (CRF) emerged in 2002 in the farming provinces of Sri Lanka. An estimate of dietary cadmium intake was between 15 and 28 microg/kg body weight per week. The mean urinary cadmium in patients diagnosed with stage 5 kidney failure was 7.6 microg/g creatinine and 11.6 microg/g for asymptomatic persons. The agrochemical triple superphosphate (TSP) fertilizer containing 23.5-71.7 mg Cd/kg was the source of cadmium added to soils. Mean Cd content in cultivated vs. uncultivated soils in Anuradhapura district was 0.02 +/- 0.01 vs. 0.11 +/- 0.19 mg/kg while in Polonnaruwa district, it was 0.005 +/- 0.004 vs. 0.016 +/- 0.005 mg/kg. Prior to the Green Revolution, the amount of fertilizer used in rice cultivation in 1970 was 32,000 metric tons (Mts) rising to 74,000 Mts in 1975. Up to 68.9 Mts of Cd could have entered into the rice-cascade reservoir environment from TSP use since 1973. Diversion of the Mahaweli River in 1970-1980 further increased cadmium input. Cadmium transfer from Upper Mahaweli water to Polgolla was 72.13 kg/day. Cadmium content of the sediments from reservoirs collecting cadmium from irrigated TSP fertilized crop fields (rice and vegetables) was 1.8-2.4 mg/kg. 2010 Elsevier Ireland Ltd. All rights reserved.

    Directory of Open Access Journals (Sweden)

    Ana Keuly Luz Bezerra

    2014-12-01

    Full Text Available This article aims to discuss the notion of civil society, hegemony and passive revolution in the thoughts of Antonio Gramsci and its relation to the need for implementation of environmental justice. The concept of civil society in Gramsci's view appears as a group of organisms commonly designated as “private”, formed by the organizations responsible for drafting much as the dissemination of ideologies, so understanding the school system, the churches, trade unions, political parties, professional organizations, material culture of the organization, while the concept of hegemony arises within the Marxist tradition as a response to new social settings. Despite its origins in the Russian social democracy and to be present at the thought of Lenin, this concept was developed in a more elaborated by Gramsci. The concept of “passive revolution”, “revolution–restoration” or “evolutionism” is crucial category that Gramsci uses to understand the formation of the modern bourgeois state in Italy (starting from the facts of the Risorgiment o, which culminated in the national unification, to define the fundamental features of the passage of Italian capitalism to step monopoly capitalism and to point fascism as a form of “passive revolution”. It is from this understanding that we use the concept of “passive revolution” to discuss pratics the principles of environmental justice, given that this concept applies to many episodes of the story, as well as more generally, the transition from the industrial model capitalist development of the capitalist system of sustainable development. It consists in a literature review from the work of Gramsci, where it can be concluded that the movements that call for environmental justice in Brazil and the world, mitigated by civil society through a process of passive revolution, based on the insertion of dignity human and the environment as key goals of the state, propose a new model of sustainable

    If we define scientific revolutions as changes of scientists' ontologies, types of causal explanation, and paradigmatic types of methods and instruments, Antoine-Laurent Lavoisier's contribution to chemistry did not amount to a scientific revolution. Contrary to the received view that Lavoisier initiated a "chemical revolution," which is accepted by Chang and Kusch, I argue that Lavoisier shared with the phlogistonists their "flat ontology" of chemical substance, established decades before the 1770s, their types of explaining chemical transformation, and their quantitative methods. Based on my historical reconstruction, I criticize Chang's argument that the late eighteenth-century phlogistic systems and Lavoisier's system belonged to two different theoretical traditions. As a consequence, I also question Chang's argument that the acceptance of Lavoisier's system can be explained in terms of dominance of "compositionism" over "principlism."

  6. A sort of revolution: Systematics and physical anthropology in the 20th century.

    Science.gov (United States)

    Cartmill, Matt

    2018-04-01

    During the first four decades of the 20th century, a system of ideas about the evolution and systematics of humans and other primates coalesced around the work of George Gaylord Simpson and W. E. Le Gros Clark. Buttressed by the "new physical anthropology" of the 1950s, that system provided an authoritative model-a disciplinary matrix or paradigm-for the practice of that aspect of biological anthropology. The Simpson-Le Gros Clark synthesis began to unravel in the 1960s and collapsed in the 1970s under the onslaught of cladistic systematics. The cladistic "revolution" resembles a paradigm shift of the sort proposed by Thomas Kuhn because it was driven, not by new biological discoveries or theories, but by a change in aesthetics. © 2017 Wiley Periodicals, Inc.

By the implementation of the SDDO, the designed joint possesses high performance such as high precision of output motion, low energy consumption, large capacity of rotation, high stiffness, simultaneously. A prismatic flexure joint and a universal flexure joint constructed of designed joints are included to illustrate the analysis and design techniques. The presented design can be usefully used in other parallel compliant mechanisms and the SDDO method can also be used to develop industrial products.

  9. 'So Much the Worse for the Whites': Dialectics of the Haitian Revolution

    Directory of Open Access Journals (Sweden)

    George Ciccariello-Maher

    2014-09-01

    Full Text Available This article sets out from an analysis of the pioneering work of Susan Buck-Morss to rethink, not only Hegel and Haiti, but broader questions surrounding dialectics and the universal brought to light by the Haitian Revolution. Reading through the lens of C.L.R. James’ The Black Jacobins, I seek to correct a series of ironic silences in her account, re-centering the importance of Toussaint’s successor, Jean-Jacques Dessalines, and underlining the dialectical importance of identitarian struggles in forging the universal. Finally, I offer Frantz Fanon’s reformulation of the Hegelian master-slave dialectic—overlooked in Buck-Morss’ account—as a corrective that allows us to truly rethink progress toward the universal in decolonized dialectical terms.

  10. Abbot A. Barruel about the Causes and Organizers of the French Revolution

    Sergey E. Kiyasov

    2017-12-01

    Full Text Available The article deal with the version of participation in the events of the French revolution of secret organizations, proposed by Catholic priest and publicist Augustin Barruel. According to the emigrant abbot, who became a witness and participant in the revolutionary processes, those events were organized by the conspirators represented by philosophers-enlighteners, masons and illuminati, who joined after 1789 in the Club of the Jacobins. A. Barruel shared his views in a multivolume work, which was published in London at the very end of the 18th century. The book aroused great interest and was translated into many languages, including Russian. From that moment, a “black legend” was approved in the assessment of the European Masonic movement. This legend explained all the revolutionary events by a destructive “Masonic conspiracy”. The author focuses the research on characterizing the real causes that had become the catalyst for the French revolution. In the context of criticism of Barruel’s views, the assessments are also given to the evolution of the Masonic movement in France of the 18th century. The author touches upon a very important problem of transformation of national Masonic organizations. This problem is considered in the context of the formation of the structures of the Great East of France. The article notes the close relationship of this structure with the elite and the Royal court. The undertaken analysis is based on the special literature and the original sources, such as The Constitutions by James Anderson – the first printed constitution of the premier Grand Lodge of England; Memoires by Augustin Barruel.

    2017-08-01

    Manufacturing companies, independent of operation sector and size, must be able to produce lot size one products, just-in-time at a competitive cost. Coping with this high adaptability and short reaction times proves to be very challenging. New approaches must be taken into consideration for designing modular, intelligent and cooperative production systems which are easy to integrate with the entire factory. The coined term for this network of intelligent interacting artefacts system is cyber-physical systems (CPS). CPS is often used in the context of Industry 4.0 - or what many consider the forth industrial revolution. The paper presents an overview of key technological and social requirements to map the Smart Factory vision into reality. Finally, global and Romanian specific challenges hindering the vision of a true Smart Factory to become reality are presented.

  17. Exploiting the information revolution: call for independent evaluation of the latest English national experiment.

    Scott, Philip

    2015-02-19

    The English National Health Service (NHS) has a long history of national experiments with information technology; some successful, others less so. The NHS England Five Year Forward View aspires to 'Exploit the information revolution' through the transformational work of the National Information Board (NIB). NIB has published a 'Framework for Action' that promotes citizen empowerment, information availability, transparency, public trust, innovation, informatics skills and societal value. The framework sets out many laudable and common sense ambitions, but is light on evidence to support its aspirations, or plans for its evaluation. Considerable resource was invested in evaluation studies in the later stages of the National Programme for IT in England, but the analyses do not seem to have been included. Most of the cited evidence is from an unpublished report by management consultants rather than independent peer-reviewed work. National experiments of this importance should be evidence based and properly evaluated so that each iteration of 'information revolution' produces an evidence base to inform subsequent generations of care provision models and technology innovation. Evaluation should be planned from the very start rather than added in as an afterthought. Like any good business plan there should be defined critical success factors for health and social care, and a declaration of how they might be measured. Unintended consequences should be qualitatively explored. Evaluation should also consider critical-interpretive social perspectives to understand the human factors in technology deployment and should seek a theoretically informed insight into the mechanisms of change. The NHS Five Year Forward View and the NIB framework set out challenging ambitions based on transformative use of information technology and collaborative partnerships with commissioners and providers. The framework stands up very well against the Hayes principles, but the learning opportunities

  18. Common mechanisms of DNA translocation motors in bacteria and viruses using one-way revolution mechanism without rotation.

    Biomotors were once described into two categories: linear motor and rotation motor. Recently, a third type of biomotor with revolution mechanism without rotation has been discovered. By analogy, rotation resembles the Earth rotating on its axis in a complete cycle every 24h, while revolution resembles the Earth revolving around the Sun one circle per 365 days (see animations http://nanobio.uky.edu/movie.html). The action of revolution that enables a motor free of coiling and torque has solved many puzzles and debates that have occurred throughout the history of viral DNA packaging motor studies. It also settles the discrepancies concerning the structure, stoichiometry, and functioning of DNA translocation motors. This review uses bacteriophages Phi29, HK97, SPP1, P22, T4, and T7 as well as bacterial DNA translocase FtsK and SpoIIIE or the large eukaryotic dsDNA viruses such as mimivirus and vaccinia virus as examples to elucidate the puzzles. These motors use ATPase, some of which have been confirmed to be a hexamer, to revolve around the dsDNA sequentially. ATP binding induces conformational change and possibly an entropy alteration in ATPase to a high affinity toward dsDNA; but ATP hydrolysis triggers another entropic and conformational change in ATPase to a low affinity for DNA, by which dsDNA is pushed toward an adjacent ATPase subunit. The rotation and revolution mechanisms can be distinguished by the size of channel: the channels of rotation motors are equal to or smaller than 2 nm, that is the size of dsDNA, whereas channels of revolution motors are larger than 3 nm. Rotation motors use parallel threads to operate with a right-handed channel, while revolution motors use a left-handed channel to drive the right-handed DNA in an anti-chiral arrangement. Coordination of several vector factors in the same direction makes viral DNA-packaging motors unusually powerful and effective. Revolution mechanism that avoids DNA coiling in translocating the lengthy genomic

  19. Joseph Lister's surgical revolution.

    Toledo-Pereyra, Luis H

    2010-10-01

    Joseph Lister (1827-1912), renowned British surgeon-scientist, introduced to the world the use and appreciation of the antiseptic method for the prevention of wound sepsis. Armed with the ideas of Louis Pasteur (1822-1895) regarding the role of microorganisms in infections or the so-called germ theory of disease, he advanced the surgical field by using antiseptics, such as carbolic acid, in the treatment of contaminated wounds. These developments constituted a real surgical revolution. No breakthrough before Lister's, except perhaps the discovery of anesthesia, had contributed to such an incredible advancement in relationship to the surgical arena. After 1867, the year in which Lister published his remarkable paper in Lancet, it was possible to appropriately treat or prevent wound infections with the use of antiseptics at the site of the operated wound. Lister's method was complicated but produced its desired effect--to diminish wound morbidity and patient mortality. His contribution was secured for future generations and a surgical revolution had begun!

    Full Text Available The aim of this study is to point to the fact that economic diplomacy is a relatively new practice in international economics, specifically the expansion of the occurrence of Intelligence Revolution. The history in global relations shows that without economic diplomacy there is no optimal economic growth and social development. It is important to note that economic diplomacy should be important for our country and the political elite, as well as for the administration of Croatian economic subjects that want to compete in international market economy. Comparative analysis are particularly highlighted by French experience. Therefore, Croatia should copy the practice of those countries that are successful in economic diplomacy. And in the curricula - especially of our economic faculties - we should introduce the course of Economic Diplomacy. It is important to note, that in order to form our optimal model of economic diplomacy which would be headed by the President of Republic of Croatia formula should be based on: Intelligence Security Agency (SOA, Intelligence Service of the Ministry of Foreign Affairs and European Integration, Intelligence Service of the Croatian Chamber of Commerce and the Intelligence Service of the Ministry of Economy, Labor and Entrepreneurship. Described model would consist of intelligence subsystem with at least twelve components.

  5. The dual Green Revolutions in South Korea: reforestation and agricultural revolution under the authoritarian regime.

    Science.gov (United States)

    Moon, Manyong

    2012-01-01

    In South Korea, the Green Revolution has been commonly understood as the development and dissemination of new rice varieties ('Tongil' rice) and the rapid increase of rice yield in the 1970s. However, revolutionary success in agriculture was not the only green revolution South Korea experienced; another green revolution lay in the success of reforestation projects. In the 1970s, South Korea's forest greening was closely related to its agricultural revolution in several ways. Therefore, South Korea's Green Revolution was an intrinsically linked double feature of agriculture and forestry. This two-pronged revolution was initiated by scientific research - yet accomplished by the strong administrative mobilization of President Park Chung Hee's regime. The process of setting goals and meeting them through a military-like strategy in a short time was made possible under the authoritarian regime, known as 'Yushin', though the administration failed to fully acknowledge scientific expertise in the process of pushing to achieve goals.

    Londoño, Diego Enrique; Dening, Tom

    2016-06-01

    This article addresses some important questions in psychiatric semiology. The concept of a sign is crucial in psychiatry. How do signs emerge, and what gives them validity and legitimacy? What are the boundaries of 'normal' and 'pathological' behaviour and mental experiences? To address these issues, we analyse the characteristics and rules that govern semiological signs and clinical elements. We examine 'normality' from the perspective of Georges Canguilehm and compare the differences of 'normal' in physiology and psychiatry. We then examine the history and the philosophical, linguistic and medical-psychiatric origins of semiology during the eighteenth and nineteenth centuries (the Age of Revolution). The field of rhetoric and oratory has emphasized the importance of passions, emotions and language as applied to signs of madness. Another perspective on semiology, provided by Michel Foucault, lays stress on the concept of 'instinct' and the axis of voluntary-involuntary behaviour. Finally, we analyse how statistics and eugenics have played an important role in our current conceptualization of the norm and therefore the scientific discourse behind the established clinical signs. © The Author(s) 2016.

  17. Constraining uncertainty in the timescale of angiosperm evolution and the veracity of a Cretaceous Terrestrial Revolution.

    Barba-Montoya, Jose; Dos Reis, Mario; Schneider, Harald; Donoghue, Philip C J; Yang, Ziheng

    2018-04-01

    Through the lens of the fossil record, angiosperm diversification precipitated a Cretaceous Terrestrial Revolution (KTR) in which pollinators, herbivores and predators underwent explosive co-diversification. Molecular dating studies imply that early angiosperm evolution is not documented in the fossil record. This mismatch remains controversial. We used a Bayesian molecular dating method to analyse a dataset of 83 genes from 644 taxa and 52 fossil calibrations to explore the effect of different interpretations of the fossil record, molecular clock models, data partitioning, among other factors, on angiosperm divergence time estimation. Controlling for different sources of uncertainty indicates that the timescale of angiosperm diversification is much less certain than previous molecular dating studies have suggested. Discord between molecular clock and purely fossil-based interpretations of angiosperm diversification may be a consequence of false precision on both sides. We reject a post-Jurassic origin of angiosperms, supporting the notion of a cryptic early history of angiosperms, but this history may be as much as 121 Myr, or as little as 23 Myr. These conclusions remain compatible with palaeobotanical evidence and a more general KTR in which major groups of angiosperms diverged later within the Cretaceous, alongside the diversification of pollinators, herbivores and their predators. © 2018 The Authors.

  18. Contraception: a social revolution.

    Benagiano, Giuseppe; Bastianelli, Carlo; Farris, Manuela

    2007-03-01

    Modern contraceptive technology is more than a technical advance: it has brought about a true social revolution, the 'first reproductive revolution' in the history of mankind. This latter was followed in rapid succession by other major changes in human reproductive strategies. In the human species, sexual activity began to lose its exclusive reproductive meaning at an early stage of its evolution. Human beings must have practiced non-conceptive sex from the outset and therefore must have had a need to avoid, rather than to seek conception during intercourse from time immemorial. The search for methods to control fertility went on for millennia, but a valid solution was only found during the twentieth century, when the population explosion had forever changed the shape of humanity: in only one century the total population of the planet had grown from some 1.6 billion to more than 6 billion. That increase will remain unique in the history of Homo sapiens. At the global level, contraception provided a tool to deal with overpopulation and, in only 50 years, went a long way towards its resolution. However, to solve the problem, national and international family planning initiatives were required. For individuals, contraception also meant a revolution. It allowed sexual intercourse without reproduction. Only 25 years later, in vitro fertilisation permitted childbearing without sexual intercourse. Other advances followed and now cloning, that is, reproduction without the two gametes, looms on the horizon. Such a series of rapid, major changes in human reproductive strategies has confused many. For this reason, a constructive dialogue between sociology and biology is mandatory. Contraception is a powerful tool to promote equity between sexes; it improves women's status in the family and in the community. Avoiding pregnancy during the teens increases opportunities for a young woman's education, training and employment. By controlling their fertility, women get a chance to

  20. Elasto/visco-plastic dynamic response of multi-layered shells of revolution

    International Nuclear Information System (INIS)

    Takezono, S.; Tao, K.; Taguchi, T.

    1989-01-01

    Many investigations of the elasto/visco-plastic dynamic response of shells have been conducted. These investigations, however, have been mostly concerned with the case of single-layered shells, and few studies on multi-layered shells have been reported in spite of their importance in engineering. In this paper, the authors study the elasto/visco-plastic dynamic response of the multi-layered shells of revolution subjected to impulsive loads. The equations of motion and the relations between the strains and displacements are derived by extending Sanders' theory for elastic thin shells. As the constitutive relation, Hooke's law is used in the linear elastic range, and the elasto/visco-plastic equations are employed in the plastic range. The criterion for yielding used in the analysis is the von Mises yield theory. In the numerical analysis of the fundamental equations for incremental values an usual finite difference form is employed for the spatial derivatives and the inertia terms are treated with the backward difference formula. The solutions are obtained by summation of the incremental values

  1. The creep of multi-layered moderately thick shells of revolution under asymmetrical loading

    International Nuclear Information System (INIS)

    Takezono, S.; Migita, K.

    1987-01-01

    In the present paper the authors study the creep deformation of the multi-layered thick shells of revolution under asymmetrical loads. The equations of equilibrium and the strain-displacement relations are derived from the Reissner-Naghdi theory (1941, 1957) for elastic shells where a consideration on the effect of shear deformation is given. In the theory of creep it is assumed that in a given increment of time the total strain increments are composed of an elastic part and a part due to creep. The elastic strains are proportional to the stresses by Hooke's law. For the constitutive equations in the creep range, McVetty's equation modified by Arrhenius' equation for thermal effect is employed. The basic differential equations on the creep problems derived for the incremental values with respect to time are numerically solved by a finite difference method and the solutions at any time are obtained by summation of the incremental values. Resultant forces and resultant moments are given from numerical integration of the stresses by Simpson's 1/3 rules. (orig./GL)

  2. Cancer research in need of a scientific revolution: Using 'paradigm shift' as a method of investigation.

    2015-09-01

    Despite important human and financial resources and considerable accumulation of scientific publications, patents, and clinical trials, cancer research has been slow in achieving a therapeutic revolution similar to the one that occurred in the last century for infectious diseases. It has been proposed that science proceeds not only by accumulating data but also through paradigm shifts. Here, we propose to use the concept of 'paradigm shift' as a method of investigation when dominant paradigms fail to achieve their promises. The first step in using the 'paradigm shift' method in cancer research requires identifying its founding paradigms. In this review, two of these founding paradigms will be discussed: (i) the reification of cancer as a tumour mass and (ii) the translation of the concepts issued from infectious disease in cancer research. We show how these founding paradigms can generate biases that lead to over-diagnosis and over-treatment and also hamper the development of curative cancer therapies. We apply the 'paradigm shift' method to produce perspective reversals consistent with current experimental evidence. The 'paradigm shift' method enlightens the existence of a tumour physiologic-prophylactic-pathologic continuum. It integrates the target/antitarget concept and that cancer is also an extracellular disease. The 'paradigm shift' method has immediate implications for cancer prevention and therapy. It could be a general method of investigation for other diseases awaiting therapy.

  3. Sensitivity analysis for the dynamic response of viscoplastic shells of revolution

    Science.gov (United States)

    Kulkarni, Makarand; Noor, Ahmed K.

    1995-01-01

    A computational procedure is presented for evaluating the sensitivity coefficients of the dynamic axisymmetric response of viscoplastic shells of revolution. The analytical formulation is based on Reissner's large deformation shell theory with the effects of transverse shear deformation, rotatory inertia and moments turning around the normal to the middle surface included. The material model is chosen to be isothermal viscoplasticity, and an associated flow rule is used with a von Mises effective stress. A mixed formulation is used with the fundamental unknowns consisting of six stress resultants, three generalized displacements and three velocity components. Spatial discretization is performed using finite elements, with discontinuous stress resultants across element interfaces. The temporal integration is performed by using an explicit central difference scheme (leap-frog method) with an implicit constitutive update. The sensitivity coefficients are evaluated using a direct differentiation approach. Numerical results are presented for a spherical cap subjected to step loading, and a circular plate subjected to impulsive loading. The sensitivity coefficients are generated by evaluating the derivatives of the response quantities with respect to thickness, mass density, Young's modulus, and two of the material parameters characterizing the viscoplastic response. Time histories of the response and sensitivity coefficients are presented, along with spatial distributions of these quantities at selected times.

  4. Dictatorship and revolution: Socio-political reconstructions of collective memory in post-authoritarian Portugal

    2014-12-01

    Full Text Available This article inserts itself into larger discussions regarding post-dictatorship memory politics in Portugal and comparative studies of similar histories of violence in Europe, particularly examinations of National-Socialism, Nazism and the Holocaust, as well as comparative studies of twentieth-century fascist dictatorships in the Iberian peninsula. In spite of the revolutionary, radical nature of the Portuguese democratisation process, studies conducted during the last four decades on the social and political (reconstructions of memory regarding the Portuguese dictatorship (1926-1974 have demonstrated that state policies regarding the past have depicted the dictatorship as one that is very similar to events in countries where the process of democratic transition was actually quite different from that of Portugal. Right-wing groups and those who self-describe as “victims” of processes of decolonisation that occurred between 1974 and 1975 have established a pattern of public debate that leaves no room for discussing the dictatorship without also referring to the 1974-1975 Revolution. This mode of debate seems to suggest that these two periods of history are indicative of a global regime phenomenon and that both the processes of decolonisation and revolution affected Portuguese society in similar ways. This paper attempts to complicate these narratives in order to question the democratic forms that emerged after the Revolution and to compare it to Salazar’s dictatorial regime.Este artículo se encuadra en una discusión más amplia sobre las políticas de la memoria de la posdictadura salazarista en Portugal, y en estudios comparados sobre historias semejantes de violencia en Europa, especialmente las relativas al nacional-socialismo, el nazismo y el Holocausto.

    Tao, K.; Takezono, S.

    1989-01-01

    An analytical method for the elasto/visco-plastic problems of general, orthotropic moderately thick shells of revolution subjected to asymmetrical loads is developed in consideration of the effect of shear deformations. The Reissner-Naghdi theory for elastic moderately thick shells is extended in this analysis. As the constitutive equation, Hooke's law for orthotropic materials is used in the elastic region, and equations based on the orthotropic visco-plastic theory derived from the orthotropic plastic theory by Hill are employed in the plastic range. The visco-plastic strain rates are related to the stresses by Perzyna's equation. The fundamental equations for the increment are numerically solved by a finite difference method and the solutions are obtained by summation of the incremental values. In order to check the adequacy of the numerical analysis, experiments are performed on the elasto/visco-plastic deformation of a titanium cylindrical shell subjected to locally distributed loads. Good agreement is obtained between the experimental results and analytical solutions

  6. Sensitivity analysis for the dynamic response of thermoviscoplastic shells of revolution

    1995-01-01

    A computational procedure is presented for evaluating the sensitivity coefficients of the dynamic axisymmetric, fully-coupled, thermoviscoplastic response of shells of revolution. The analytical formulation is based on Reissner's large deformation shell theory with the effects of large-strain, transverse shear deformation, rotatory inertia and moments turning around the normal to the middle surface included. The material model is chosen to be viscoplasticity with strain hardening and thermal hardening, and an associated flow rule is used with a von Mises effective stress. A mixed formulation is used for the shell equations with the fundamental unknowns consisting of six stress resultants, three generalized displacements and three velocity components. The energy-balance equation is solved using a Galerkin procedure, with the temperature as the fundamental unknown. Spatial discretization is performed in one dimension (meridional direction) for the momentum and constitutive equations of the shell, and in two dimensions (meridional and thickness directions) for the energy-balance equation. The temporal integration is performed by using an explicit central difference scheme (leap-frog method) for the momentum equation; a predictor-corrector version of the trapezoidal rule is used for the energy-balance equation; and an explicit scheme consistent with the central difference method is used to integrate the constitutive equations. The sensitivity coefficients are evaluated by using a direct differentiation approach. Numerical results are presented for a spherical cap subjected to step loading.

    2014-11-01

    Epigenetics is one of the most rapidly expanding fields in the life sciences. Its rise is frequently framed as a revolutionary turn that heralds a new epoch both for gene-based epistemology and for the wider discourse on life that pervades knowledge-intensive societies of the molecular age. The fundamentals of this revolution remain however to be scrutinized, and indeed the very contours of what counts as 'epigenetic' are often blurred. This is reflected also in the mounting discourse on the societal implications of epigenetics, in which vast expectations coexist with significant uncertainty about what aspects of this science are most relevant for politics or policy alike. This is therefore a suitable time to reflect on the directions that social theory could most productively take in the scrutiny of this revolution. Here we take this opportunity in both its scholarly and normative dimension, that is, proposing a roadmap for social theorizing on epigenetics that does not shy away from, and indeed hopefully guides, the framing of its most socially relevant outputs. To this end, we start with an epistemological reappraisal of epigenetic discourse that valorizes the blurring of meanings as a critical asset for the field and privileged analytical entry point. We then propose three paths of investigation. The first looks at the structuring elements of controversies and visions around epigenetics. The second probes the mutual constitution between the epigenetic reordering of living phenomena and the normative settlements that orient individual and collective responsibilities. The third highlights the material import of epigenetics and the molecularization of culture that it mediates. We suggest that these complementary strands provide both an epistemically and socially self-reflective framework to advance the study of epigenetics as a molecular juncture between nature and nurture and thus as the new critical frontier in the social studies of the life sciences.

  13. The psychology of thinking before the cognitive revolution: Otto Selz on problems, schemas, and creativity.

    2010-02-01

    Otto Selz has been hailed as one of the most important precursors of the cognitive revolution, yet surprisingly few studies of his work exist. He is often mentioned in the context of the Würzburg School of the psychology of thinking and sometimes in the context of Gestalt psychology. In this paper, it is argued that Selz's emphasis on the role of problems and schemas in the direction of thought processes and creativity sets him apart from the program of the Würzburg School. On the other hand, by developing a theory of thinking that is exclusively at the intentional level, Selz also differs from psychologists that take physics as a model for psychology, such as the Gestalt psychology of Wolfgang Kihler. Special emphasis is given in this paper to Selz's use of the concept of problem or task and the concept of the schema. It is further argued that the concept of the schema is the result of Selz's adaptation of the theory of relations as developed by the philosopher Meinong. The paper begins with a sketch of Selz's life that ended so tragically.

    Tao Zhang; Mustiere, Fred; Micheyl, Christophe

    2016-08-01

    The first revolution in hearing aids came from nonlinear amplification, which allows better compensation for both soft and loud sounds. The second revolution stemmed from the introduction of digital signal processing, which allows better programmability and more sophisticated algorithms. The third revolution in hearing aids is wireless, which allows seamless connectivity between a pair of hearing aids and with more and more external devices. Each revolution has fundamentally transformed hearing aids and pushed the entire industry forward significantly. Machine learning has received significant attention in recent years and has been applied in many other industries, e.g., robotics, speech recognition, genetics, and crowdsourcing. We argue that the next revolution in hearing aids is machine intelligence. In fact, this revolution is already quietly happening. We will review the development in at least three major areas: applications of machine learning in speech enhancement; applications of machine learning in individualization and customization of signal processing algorithms; applications of machine learning in improving the efficiency and effectiveness of clinical tests. With the advent of the internet of things, the above developments will accelerate. This revolution will bring patient satisfactions to a new level that has never been seen before.

  16. The Identity Process in Times of Rupture: Narratives From the Egyptian Revolution

    Sarah Hassan Awad

    2016-05-01

    Full Text Available This is a longitudinal study of the identity process through times of dramatic social change. Using a narrative psychological approach this research follows the life stories of five Egyptian bloggers as they write their stories on online blogs over the course of the three years following the 2011 revolution, at which time Egypt has witnessed major social and political changes. The aim is to understand the identity process of individuals as they develop and adapt through changing social contexts and how they create alternative social relations as they engage in prefigurative politics. The findings shed light on how ruptures trigger a process of reflexivity, adaptive learning, and sense-making that facilitates coping and the reconstruction of a positive identity after ruptures. It also suggests that the narration of the experience of rupture through storytelling creates a heightened sense of agency in individuals’ ability to create new meanings of their world in spite of the socio-cultural and political constraints. This study presents narratives as an informing methodological resource that connects identity process with social representations and emphasizes the value of storytelling as an integral part of the adaptation process.

    Full Text Available The article outlines Chinese literature following the establishment of the People’s Republic of China in relation to Mao’s Communist policy. It presents the occurrence of Misty poetry as an opposition to the political ideology of the Great Cultural Revolution (1966–1976. Misty poetry is understood as a spontaneous illegal poetic movement of individuals who veiled their political demands directed against Mao’s ideology in metaphors. This oppositional stance resembled the movement of 4th May 1919 which took place after the collapse of the last Chinese dynasty and criticised the traditional dominant ideology of Confucianism and sought democratization of the Chinese society. The same desire was shared by the Misty poets but this time under the dominance of the political ideology of the Chinese Communist Party in the period following 1942 which was indicated by Mao Zedong in his speech in Yan’an. Mao’s policy was repressive in nature since the role of literature and art, and thereby also poetry, was seen only as being utilitarian and was thus sealed in the dictated reflection of the class struggle. Therefore, in essence, the communist period laid its path to capitalism.

    2018-01-01

    The reform of the penitentiary system (law 103/2017) which is about to enter into force in Italy represents a Copernican revolution for the management of psychiatric patients who are also authors of a crime. The change would have consequences similar to what happened with the law 180 of 1978. The basic principles on which the new Law is based are: 1) the extension of the faculty to suspend the sentence also for inmates and prisoners affected by a serious mental illness; 2) the full integration of the National Health System (SSN) and DSM in the penitentiary institutions; 3) the establishment of "sections for prisoners with disabilities", special sections for exclusive management for individuals with mental disorders, to be implemented inside the prisons and jails; 4) the possibility probation and parole for prisoners with sentences up to 6 years if suffering from mental illness with a procedure similar to the one already enacted for persons with drug dependency. The article deals with the positive aspects of the reform, but also with the critical aspects it presents in its implementation aspects: training of prison police officers and health workers; substantial and decisive employment of psychiatry in penal institutions; control functions by the DSM on patients; lack of staff and funds. The final aim of the reform is to contain recidivism, and the system must be organized on this goal.

    Full Text Available The emerging Knowledge Revolution goes beyond the changing technologies and the challenges and opportunities they create to include the structure of knowledge and how it is transmitted inter-generationally and across countries. There are seven major features of that profound transformation, which I call “The Seven Pillars of the New Knowledge Revolution”. These are: (i Parsing, Life & Organization; (ii Image & Text; (iii Humans & Machines; (iv Complexity & Chaos; (v Computation & Research; (vi Convergence & Transformation; and (vii Pluridisciplinarity & Policy. This diagnosis has profound implications on how one should think about the design and management of our institutions of learning, starting not only with universities, but also the school system, as well as our research institutions (whether in universities or in public and private labs, and the supporting institutions of knowledge (like museums, libraries and archives. Radical proposals are advanced for the content, method, participants and organizational setting of education, as well as the role of the University as mediator of transitions, its relationship with society and economy, as well as its physical presence, governance structure and the values it should promote. Core functions and curricula for the future, along with the possibility of a global university consortium, are discussed.

    Coleoid cephalopod molluscs comprise squid, cuttlefish and octopuses, and represent nearly the entire diversity of modern cephalopods. Sophisticated adaptations such as the use of colour for camouflage and communication, jet propulsion and the ink sac highlight the unique nature of the group. Despite these striking adaptations, there are clear parallels in ecology between coleoids and bony fishes. The coleoid fossil record is limited, however, hindering confident analysis of the tempo and pattern of their evolution. Here we use a molecular dataset (180 genes, approx. 36 000 amino acids) of 26 cephalopod species to explore the phylogeny and timing of cephalopod evolution. We show that crown cephalopods diverged in the Silurian-Devonian, while crown coleoids had origins in the latest Palaeozoic. While the deep-sea vampire squid and dumbo octopuses have ancient origins extending to the Early Mesozoic Era, 242 ± 38 Ma, incirrate octopuses and the decabrachian coleoids (10-armed squid) diversified in the Jurassic Period. These divergence estimates highlight the modern diversity of coleoid cephalopods emerging in the Mesozoic Marine Revolution, a period that also witnessed the radiation of most ray-finned fish groups in addition to several other marine vertebrates. This suggests that that the origin of modern cephalopod biodiversity was contingent on ecological competition with marine vertebrates. © 2017 The Authors.

  2. Peasant friendly plant breeding and the early years of the green revolution in Mexico.

    2009-01-01

    Despite their success in boosting cereals production overall, the Green Revolution programs of the 1950s and 1960s were often criticized for failing to achieve their declared aim of alleviating world hunger. Most critics argued that the programs had produced a technology unsuited to the needs of small peasant farmers. This paper explores why such inappropriate technology might have been developed, focusing on the early years of the Rockefeller Foundation's Mexican Agricultural Program (MAP). It shows that some foundation officers as well as agricultural advisors had prior experience of the problems faced by small farmers in the United States and elsewhere. Moreover, the foundation's expressed concern for rural poverty does not appear to have been mere posturing by an organization anxious to be seen as an agent of philanthropy. Furthermore, the program's early work in maize-breeding was well tailored to the conditions of Mexican agriculture. Once the MAP was up and running, however, it became apparent that the task of getting new varieties and cultivation practices to small farmers was going to be difficult. Needing to make some kind of impact quickly, MAP staff chose to concentrate upon projects that were likely to find a rapid uptake. This meant setting aside the needs of peasant farmers to develop high-yielding varieties suited to large commercial farms.

    Hospitals are expected to serve the medical needs of casualties in the face of a disaster or other crisis, including man-made conflicts. The aim of this study was to evaluate the impact of the 2011 Yemeni revolution on hospital disaster preparedness in the capital city of Sana'a. The study was conducted in September 2011 and 2013. For evaluation purposes, the hospital emergency response checklist published by the World Health Organization (WHO) was used. Additional information was also obtained to determine what steps were being taken by hospital authorities to improve hospital preparedness. The study selected 11 hospitals. At the time of the first evaluation, 7 hospitals were rated "unacceptable" for level of preparedness and 4 were rated "insufficient," receiving a WHO checklist rating of 10 to 98. At the second evaluation, 5 hospitals were rated "unacceptable," 3 "insufficient," and 1 "effective," receiving a rating of 9 to 134. Unfortunately, this study shows that between 2011 and 2013, no significant progress was made in hospital disaster preparedness in Sana'a. In a disaster-prone country like Yemen, the current situation calls for drastic improvement. Health system authorities must take responsibility for issuing strategic plans as well as standards, guidelines, and procedures to improve hospital disaster preparedness.

    In the Southern Hemisphere, evidence for preindustrial atmospheric pollution is restricted to a few geological archives of low temporal resolution that record trace element deposition originating from past mining and metallurgical operations in South America. Therefore the timing and the spatial impact of these activities on the past atmosphere remain poorly constrained. Here we present an annually resolved ice-core record (793-1989 AD) from the high altitude drilling site of Quelccaya (Peru) that archives preindustrial and industrial variations in trace elements. During the pre-colonial period (i.e., pre-1532 AD), the deposition of trace elements was mainly dominated by the fallout of aeolian dust and of ash from occasional volcanic eruptions indicating that metallurgic production during the Inca Empire (1438-1532 AD) had a negligible impact on the South American atmosphere. In contrast, a widespread anthropogenic signal is evident after 1540 AD, which corresponds with the beginning of colonial mining and metallurgy in Peru and Bolivia, 240 years prior to the Industrial Revolution. This shift was due to a major technological transition for silver extraction in South America (1572 AD), from lead-based smelting to mercury amalgamation, which precipitated a massive increase in mining activities. However, deposition of toxic trace metals during the Colonial era was still several factors lower than 20th century pollution that was unprecedented over the entirety of human history.

    Full Text Available Abstract The fourth industrial revolution stimulates the advances of science and technology, in which the Internet of Things (IoT and its supporting technologies serve as backbones for Cyber-Physical Systems (CPS and smart machines are used as the promoters to optimize production chains. Such advancement goes beyond the organizational and territorial boundaries, comprising agility, intelligence, and networking. This scenario triggers governmental efforts that aim at defining guidelines and standards. The speed and complexity of the transition to the new digitalization era in a globalized environment, however, does not yet allow a common and coordinated understanding of the impacts of the actions undertaken in different countries and regions. The aim of this paper, therefore, is to bridge this gap through a systematic literature review that identifies the most influential public policies and evaluates their existing differences. This cross-country/region comparison provides a worldwide panorama of public policies' durations, main objectives, available funding, areas for action, focused manufacturing sectors, and prioritized technologies. Findings of this review can be used as the basis to analyse the position of a country against the existing challenges imposed towards its own industrial infrastructure and also to coordinate its public policies.

    The development of rehabilitation has traditionally focused on measurements of motor disorders and measurements of the improvements produced during the therapeutic process; however, physical rehabilitation sciences have not focused on understanding the philosophical and scientific principles in clinical intervention and how they are interrelated. The main aim of this paper is to explain the foundation stones of the disciplines of physical therapy, occupational therapy, and speech/language therapy in recovery from motor disorder. To reach our goals, the mechanistic view and how it is integrated into physical rehabilitation will first be explained. Next, a classification into mechanistic therapy based on an old version (automaton model) and a technological version (cyborg model) will be shown. Then, it will be shown how physical rehabilitation sciences found a new perspective in motor recovery, which is based on functionalism, during the cognitive revolution in the 1960s. Through this cognitive theory, physical rehabilitation incorporated into motor recovery of those therapeutic strategies that solicit the activation of the brain and/or symbolic processing; aspects that were not taken into account in mechanistic therapy. In addition, a classification into functionalist rehabilitation based on a computational therapy and a brain therapy will be shown. At the end of the article, the methodological principles in physical rehabilitation sciences will be explained. It will allow us to go deeper into the differences and similarities between therapeutic mechanism and therapeutic functionalism.

    Three dimensional computational-fluid-dynamics simulations are performed for the fluid flow within a 40 rod fuel bundle in a square arrangement with a central moderator channel. To ensure spacing between the rods, the design of the bundle uses thin wires wrapped counter-clockwise around each rod. This geometry is presently investigated in the framework of the European High-Performance Light-Water Reactor (HPLWR), which operates at supercritical pressure of 25 MPa. A section with one revolution located in the evaporator region of the HPLWR core is investigated using hydraulic (to ensure fully developed flow inlet boundary conditions and reference for heated cases) and thermal-hydraulic boundary conditions. The geometry of wrapped wires gives rise to additional mixing and a circulating or 'sweeping' flow near the outer and inner regions of the fuel element next to the wall of the so called fuel assembly and moderator box. Some interesting flow features associated with the complex three-dimensional flow with significant transverse velocity components are visualized as the first evaluated result of this diversified investigation.

    Full Text Available The article discusses current state of Russian electric power industry and the main problems of its development in the future of global energy revolution, which will lead to a significant increase in share of renewable energy in global production and consumption of energy and use of industrial energy storage, and will make it possible to change the structure of the industry and significantly reduce electricity prices. Traditional energy generation displacement by renewables associated with emergence of new, more cost effective technologies. Producers of “disruptive technologies” receive advantages over importers of innovations, which are especially noticeable during the formation of the new technological wave. Considering possibilities of effective development of Russian power industry, it is important to take into account the realities, including high level of depreciation of equipment, lack of capital and technologies. Currently, in the field of technology in the power industry innovative economies of Japan, USA, UK, Canada, as well as dynamically developing economy of China are leading. The high level of patent activity in these countries is caused by presence of infrastructure which promotes the commercialization of new technologies and free access to investment capital. In Russia technological exports in power sector occurs mainly due to foreign projects of Rosatom. Operation of foreign-made equipment which accounts for a significant proportion of fixed assets and problems with the development and introduction of competitive technologies are complicated by the lack of investment in domestic market. For maintenance of imported equipment Russian companies have to buy spare parts abroad and to enter into service contracts with foreign suppliers. High depreciation of fixed assets also determines the need for new investment inflows into the sector. Thus the existing dependence on foreign investors is supposed to increase. In the short term

    Full Text Available This paper presents evidence from interviews in 2015–2016 with a nationally representative sample of Tunisia’s 15–29 year olds. We focus on the sample’s political participation and orientations during the revolution of 2011 and subsequently. We find that just 6.6 percent of those aged 15–24 at the time played any direct part in the ‘events of 2011’. Political engagement then and subsequently is shown to have been influenced most strongly by a university education and growing up in a politically engaged family. In 2015–2016, young people were overwhelmingly pro-democracy, supported equal opportunities and status for the sexes, and endorsed values of self-expression, but attached equal importance to economic security and betterment, felt that their country’s traditions should be maintained and respected, and were personally religious, though three-quarters wanted religion to be kept out of politics and government. Although Tunisia is the sole Arab Spring country to emerge with a still functioning (in 2017 multi-party democracy, we find that in 2015–2016, the majority of young people did not trust their elected politicians. Our survey findings suggest explanations for the paradox between young Tunisians’ overwhelming support for democracy alongside intense disappointment with the outcomes.

    Recently, several approaches have been reported to improve the dissolution rate and bioavailability of furosemide, a class IV drug. However, to the best of our knowledge, none of them proposed nanocrystals. In the last decade, nanocrystals successfully addressed solubility issues by increasing surface area and saturation solubility, both leading to an increase in the dissolution rate of poor water soluble drugs. The preparation of furosemide nanocrystals was by a rotation revolution mixer method. Size distribution and morphology were performed using laser diffraction and scanning electron microscopy, respectively. In addition, differential scanning calorimetry, thermogravimetry, X-ray powder diffraction (XRD) and low frequency shift-Raman spectroscopy allowed investigating the thermal properties and crystalline state. Solubility saturation and intrinsic dissolution rate (IDR) studies were conducted. The thermal analysis revealed lower melting range for the nanocrystals comparing to furosemide. Moreover, a slight crystalline structure change to the amorphous state was observed by XRD and confirmed by low frequency shift Raman. The particle size was reduced to 231 nm with a polydispersity index of 0.232, a 30-fold reduction from the original powder. Finally, the saturation solubility and IDR showed a significant increase. Furosemide nanocrystals showed potential for development of innovative formulations as an alternative to the commercial products.

    With the expanding pharmaceuticalization of public health, anthropologists have begun to examine how biomedicine's promissory discourses of normalization and demarginalization give rise to new practices of and criteria for citizenship. Much of this work focuses on the biomedicine-citizenship nexus in less-developed, resource-poor contexts. But how do we understand this relationship in resource-rich settings where medicines are readily available, often affordable, and a highly commonplace response to illness? In particular, what does it mean to not use pharmaceuticals for a treatable infectious disease in this context? We are interested in these questions in relation to the recent push for early and universal treatment for HIV infection in Australia for the twin purposes of individual and community health. Drawing on Ecks's concept of pharmaceutical citizenship, we examine the implications for citizenship among people with HIV who refuse or delay recommended medication. We find that moral and normative expectations emerging in the new HIV "treatment revolution" have the capacity to both demarginalize and marginalize people with HIV. © 2016 by the American Anthropological Association.

  16. Finding of widespread viral and bacterial revolution dsDNA translocation motors distinct from rotation motors by channel chirality and size.

    Double-stranded DNA translocation is ubiquitous in living systems. Cell mitosis, bacterial binary fission, DNA replication or repair, homologous recombination, Holliday junction resolution, viral genome packaging and cell entry all involve biomotor-driven dsDNA translocation. Previously, biomotors have been primarily classified into linear and rotational motors. We recently discovered a third class of dsDNA translocation motors in Phi29 utilizing revolution mechanism without rotation. Analogically, the Earth rotates around its own axis every 24 hours, but revolves around the Sun every 365 days. Single-channel DNA translocation conductance assay combined with structure inspections of motor channels on bacteriophages P22, SPP1, HK97, T7, T4, Phi29, and other dsDNA translocation motors such as bacterial FtsK and eukaryotic mimiviruses or vaccinia viruses showed that revolution motor is widespread. The force generation mechanism for revolution motors is elucidated. Revolution motors can be differentiated from rotation motors by their channel size and chirality. Crystal structure inspection revealed that revolution motors commonly exhibit channel diameters larger than 3 nm, while rotation motors that rotate around one of the two separated DNA strands feature a diameter smaller than 2 nm. Phi29 revolution motor translocated double- and tetra-stranded DNA that occupied 32% and 64% of the narrowest channel cross-section, respectively, evidencing that revolution motors exhibit channel diameters significantly wider than the dsDNA. Left-handed oriented channels found in revolution motors drive the right-handed dsDNA via anti-chiral interaction, while right-handed channels observed in rotation motors drive the right-handed dsDNA via parallel threads. Tethering both the motor and the dsDNA distal-end of the revolution motor does not block DNA packaging, indicating that no rotation is required for motors of dsDNA phages, while a small-angle left-handed twist of dsDNA that is

  17. The dispersion of pederasty and the athletic revolution in sixth-century BC Greece.

    Dorian Crete and Thebes are conventionally seen by ancient sources as the originators of pederasty; modern historians see support for this view in Dorian male-centered militarism and sexual segregation in upbringing. Here athletic culture, including training, nudism, and competition, is argued to be a chief 'trigger' for the emergence of pederasty in Sparta and its relatively rapid spread to other Greek states in the seventh to sixth centuries BC. Athletic nudity, in particular, was not a device to enforce civic egalitarianism, as some have argued, but is a persistently erotic incentive that reinforces hegemonic maleness and advertises the individual's virtuous exercise of restraint. In particular, Sparta is found to be the likely source of generalized athletic nudity combined with open pederasty in the early seventh century BC. Nudism in Greek art is erotically charged and not, as others argue, simply a gender marker in the seventh century. Generalized athletic nudity spread to other Greek states emulating the successful Spartan model by the 'athletic revolution' of the early sixth century. With athletic nudity, open pederasty, again following Sparta, was fostered.

  19. Traditional perceptions and treatment of mental disorders in western Ethiopia before the 1974 revolution.

    Science.gov (United States)

    Jacobsson, L; Merdasa, F

    1991-11-01

    This article describes the traditional concepts and treatment of mental disorders in the Oromo areas in western Ethiopia before the revolution in 1974. There are three traditional cultural influences operating: traditional Oromo thinking, the Coptic church and the Islamic culture. One important element in traditional Oromo thinking is that each person is believed to possess an ayana, which is a special divine agent that can descend upon people, but also means a person's character and personality. In the traditional Oromo society, the Kallu is the religious leader who, through an ecstatic ritual technique, can investigate the causes of the disorder and advise what to do. Mental disorders are generally explained as resulting from disturbances in the relationship between people and divinity. The second important cultural element in western Ethiopia is the orthodox Coptic church, which usually looks upon mental disorders as possession by evil spirits, which are thus treated by specially gifted priests and monks by praying and giving holy water or eventually exhortation. According to Islamic teaching in the area, mental disorders are caused by evil spirits sent by God to punish the unfaithful people. Some Muslim sheiks treat mental cases with prayers, but herbal remedies are also used. There is a great intermingling of these different cultural and religious elements and people attend different healers and religious leaders more depending on the reputation of the person than on cultural and religious affiliation.

  20. [Amputation and equipment of the lower limb during the Revolution and the Empire].

    Vesselle, Benoît

    2014-01-01

    During the French Revolution and Napoleon's campaigns, above-knee or below-knee amputations were performed either immediately or with a delay, which favoured septic problems. A rapidly operated amputation by a well-trained surgeon was the best way to save the life of a soldier who suffered from an open comminuted fracture of a limb. The conditions on military campaigns were indeed hard ones: doctors and surgeons had practically no resources and the transportation of severely injured persons was difficult. Such conditions favoured the pain and the danger caused by an injury, and it was rather impossible for the medical corps to lavish repeated treatments on the wounds. The amputated soldiers were then given prostheses: either a traditional peg-leg, with a flexed knee joint for trans-tibial amputations, or an "imitative" prosthesis, which tended to look like a real leg with eventually an articulated knee or foot. The author mentions famous or unrecognized amputated men, describing significant events.

    2014-01-01

    The article takes hedonism and revolution as a vantage point to discuss the Kommune 2, an experiment in collective living, the anti-authoritarian kindergardens for the under-fives, and, last but not least, a speech in 1968 that spurred the women's movement in Western Germany. The author's interest is on the materials documenting how the Berlin student movement saw psychoanalysis: One point was that the pleasure principle should replace the reality principle for the sake of humankind, another that the authoritarian character structure has its roots in the denial of sexuality. Kindergarden children supposedly need "de-individualized identification" to develop ego-strength, when boys and girls differ in their superego organization. An important accomplishment was a group analysis conducted without an analyst, an experiment that worked amazingly well in the Kommune 2. In all, these various experiments in emancipation, with psychoanalysis a guide to interpersonal understanding, may be deemed spectacular when their aftereffects on everyday life in Germany have been tremendous.

    Image analysis and computer vision can be effectively employed to recover the three-dimensional structure of imaged objects, together with their surface properties. In this paper, we address the problem of metric reconstruction and texture acquisition from a single uncalibrated view of a surface of revolution (SOR). Geometric constraints induced in the image by the symmetry properties of the SOR structure are exploited to perform self-calibration of a natural camera, 3D metric reconstruction, and texture acquisition. By exploiting the analogy with the geometry of single axis motion, we demonstrate that the imaged apparent contour and the visible segments of two imaged cross sections in a single SOR view provide enough information for these tasks. Original contributions of the paper are: single view self-calibration and reconstruction based on planar rectification, previously developed for planar surfaces, has been extended to deal also with the SOR class of curved surfaces; self-calibration is obtained by estimating both camera focal length (one parameter) and principal point (two parameters) from three independent linear constraints for the SOR fixed entities; the invariant-based description of the SOR scaling function has been extended from affine to perspective projection. The solution proposed exploits both the geometric and topological properties of the transformation that relates the apparent contour to the SOR scaling function. Therefore, with this method, a metric localization of the SOR occluded parts can be made, so as to cope with them correctly. For the reconstruction of textured SORs, texture acquisition is performed without requiring the estimation of external camera calibration parameters, but only using internal camera parameters obtained from self-calibration.

    1971-06-01

    In an age beset by social and political revolutions, the Green Revolution deals with the most basic of human needs and offers scope for better balance between the growing population and its food requirements. This report takes a close look at how nuclear techniques are being utilized in modern agricultural research to augment the Green Revolution. The Green Revolution is basically the growing of new, higher yielding cereal varieties, particularly wheat and rice, in the developing countries of Asia and Latin America. Many of the new varieties were developed by plant breeders in the Philippines, the United States of America and in Mexico, among whom is Norman Borlaug, who was recently awarded die Nobel Peace Prize for his work. This report deals only with the additional scientific contribution that nuclear techniques are making and can make to sustain and expand the Green Revolution. In this sense it complements other reports dealing with the contributions of the non-nuclear techniques, which are primarily responsible for the Green Revolution.

    The human body generates heat capable of raising body temperature by approximately 1°C per hour. Normally, this heat is dissipated by means of a thermoregulatory system. Disorders resulting from abnormally high or low body temperature result in neurologic dysfunction and pose a threat to life. In response to thermal stress, maintenance of normal body temperature is primarily maintained by convection and evaporation. Hyperthermia results from abnormal temperature regulation, leading to extremely elevated body temperature while fever results from a normal thermoregulatory mechanism operating at a higher set point. The former leads to specific clinical syndromes with inability of the thermoregulatory mechanism to maintain a constant body temperature. Heat related illness encompasses heat rash, heat cramps, heat exhaustion and heat stroke, in order of severity. In addition, drugs can induce hyperthermia and produce one of several specific clinical syndromes. Hypothermia is the reduction of body temperature to levels below 35°C from environmental exposure, metabolic disorders, or therapeutic intervention. Management of disorders of body temperature should be carried out decisively and expeditiously, in order to avoid secondary neurologic injury. © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Orbital pseudotumor is a benign disease involving the orbital structures. Pseudotumor of the ciliary body is rare. We present a case of a 27-year-old male who presented with gradual visual loss, pain, and redness in his left eye. On examination he was found to have a yellowish white mass at the periphery of anterior chamber in his left eye and ultrasound biomicroscopy (UBM revealed a ciliary body mass in the same eye. He was treated with systemic steroids, which was tapered over a period of 8 weeks. His symptoms improved and the ciliary body mass disappeared with no recurrence over the next 6 months. UBM is an important diagnostic tool for diagnosing ciliary body mass. Early diagnosis and prompt treatment with systemic steroids may help resolve pseudotumor of the ciliary body.

    Whilde, Jenny; Martindale, Mark Q; Duffy, David J

    2017-05-01

    The current species extinction crisis is being exacerbated by an increased rate of emergence of epizootic disease. Human-induced factors including habitat degradation, loss of biodiversity and wildlife population reductions resulting in reduced genetic variation are accelerating disease emergence. Novel, efficient and effective approaches are required to combat these epizootic events. Here, we present the case for the application of human precision medicine approaches to wildlife medicine in order to enhance species conservation efforts. We consider how the precision medicine revolution, coupled with the advances made in genomics, may provide a powerful and feasible approach to identifying and treating wildlife diseases in a targeted, effective and streamlined manner. A number of case studies of threatened species are presented which demonstrate the applicability of precision medicine to wildlife conservation, including sea turtles, amphibians and Tasmanian devils. These examples show how species conservation could be improved by using precision medicine techniques to determine novel treatments and management strategies for the specific medical conditions hampering efforts to restore population levels. Additionally, a precision medicine approach to wildlife health has in turn the potential to provide deeper insights into human health and the possibility of stemming and alleviating the impacts of zoonotic diseases. The integration of the currently emerging Precision Medicine Initiative with the concepts of EcoHealth (aiming for sustainable health of people, animals and ecosystems through transdisciplinary action research) and One Health (recognizing the intimate connection of humans, animal and ecosystem health and addressing a wide range of risks at the animal-human-ecosystem interface through a coordinated, collaborative, interdisciplinary approach) has great potential to deliver a deeper and broader interdisciplinary-based understanding of both wildlife and human

  16. The Revolution in Viral Genomics as Exemplified by the Bioinformatic Analysis of Human Adenoviruses

    Directory of Open Access Journals (Sweden)

    Sarah Torres

    2010-06-01

    Full Text Available Over the past 30 years, genomic and bioinformatic analysis of human adenoviruses has been achieved using a variety of DNA sequencing methods; initially with the use of restriction enzymes and more currently with the use of the GS FLX pyrosequencing technology. Following the conception of DNA sequencing in the 1970s, analysis of adenoviruses has evolved from 100 base pair mRNA fragments to entire genomes. Comparative genomics of adenoviruses made its debut in 1984 when nucleotides and amino acids of coding sequences within the hexon genes of two human adenoviruses (HAdV, HAdV–C2 and HAdV–C5, were compared and analyzed. It was determined that there were three different zones (1-393, 394-1410, 1411-2910 within the hexon gene, of which HAdV–C2 and HAdV–C5 shared zones 1 and 3 with 95% and 89.5% nucleotide identity, respectively. In 1992, HAdV-C5 became the first adenovirus genome to be fully sequenced using the Sanger method. Over the next seven years, whole genome analysis and characterization was completed using bioinformatic tools such as blastn, tblastx, ClustalV and FASTA, in order to determine key proteins in species HAdV-A through HAdV-F. The bioinformatic revolution was initiated with the introduction of a novel species, HAdV-G, that was typed and named by the use of whole genome sequencing and phylogenetics as opposed to traditional serology. HAdV bioinformatics will continue to advance as the latest sequencing technology enables scientists to add to and expand the resource databases. As a result of these advancements, how novel HAdVs are typed has changed. Bioinformatic analysis has become the revolutionary tool that has significantly accelerated the in-depth study of HAdV microevolution through comparative genomics.

    Tongil (IR667-98-1-2) rice, developed in 1972, is a high-yield rice variety derived from a three-way cross between indica and japonica varieties. Tongil contributed to the self-sufficiency of staple food production in Korea during a period known as the 'Korean Green Revolution'. We analyzed the nucleotide-level genome structure of Tongil rice and compared it to those of the parental varieties. A total of 17.3 billion Illumina Hiseq reads, 47× genome coverage, were generated for Tongil rice. Three parental accessions of Tongil rice, two indica types and one japonica type, were also sequenced at approximately 30x genome coverage. A total of 2,149,991 SNPs were detected between Tongil and Nipponbare varieties. The average SNP frequency of Tongil was 5.77 per kb. Genome composition was determined based on SNP data by comparing Tongil with three parental genome sequences using the sliding window approach. Analyses revealed that 91.8% of the Tongil genome originated from the indica parents and 7.9% from the japonica parent. Copy numbers of SSR motifs, ORF gene distribution throughout the whole genome, gene ontology (GO) annotation, and some yield-related QTLs or gene locations were also comparatively analyzed between Tongil and parental varieties using sequence-based tools. Each genetic factor was transferred from the parents into Tongil rice in amounts that were in proportion to the whole genome composition. Tongil was derived from a three-way cross among two indica and one japonica varieties. Defining the genome structure of Tongil rice demonstrates that the Tongil genome is derived primarily from the indica genome with a small proportion of japonica genome introgression. Comparative gene distribution, SSR, GO, and yield-related gene analysis support the finding that the Tongil genome is primarily made up of the indica genome.

    A suppressor screen using dwarf mutants of barley (Hordeum vulgare L.) led to the isolation of 'overgrowth' derivatives, which retained the original dwarfing gene but grew at a faster rate because of a new mutation. The new mutations were in the Slender1 (Sln1) gene (11/13 cases), which encodes the DELLA protein central to gibberellin (GA) signalling, showed 100% genetic linkage to Sln1 (1/13), or were in the Spindly1 (Spy1) gene (1/13), which encodes another protein involved in GA signalling. The overgrowth mutants were characterized by increased GA signalling, although the extent still depended on the background GA biosynthesis capacity, GA receptor function, and DELLA activity. A comparison between two GA responses, α-amylase production and leaf growth rate, revealed degrees of specificity for both the overgrowth allele and the GA response under consideration. Many overgrowth mutants were also isolated in a dwarf line of bread wheat (Triticum aestivum L.) and 19 new alleles were identified in the Rht-B1 gene, one of the 'Green Revolution' semi-dwarfing genes and the orthologue of Sln1. The sites of amino acid substitutions in the DELLA proteins of both species provide insight into DELLA function, and included examples where identical but independent substitutions were observed. In both species, the starting lines were too dwarfed to be directly useful in breeding programmes, but new overgrowth derivatives with semidwarf heights have now been characterized. The variation they exhibit in GA-influenced traits identifies novel alleles with perfect markers that are of potential use in breeding.

    Full Text Available This article addresses the materialist theory of development and fall of Marxism based on the theory of value as originally considered and presented by Karl Marx in Grundrisse and in Crítica da Economia Política, claiming that the production of value depends on labor force. As it takes place today, capital displaces labor force in every industry, service and activity, country, territory and region all over the world; workers are dismissed and are transferred to speculative activities of the fictional capital. This lesser disposition of labor force eventually harms the mean profit rate and, as time goes by, it provokes a crisis. The present capitalist crisis is resultant from the insufficiency and, to certain extent, to the incapacity of mechanisms from the system to generate enough value production in the labor process, to provide value to the invested capital (in settings of production, raw matter, and in labor force or variable capital; to create more value and to regain increased profit rate. These restraints of the financial capital (fictional capital cause a deviation to the speculative plan and contribute for the formation of tragic speculative bubbles in sectors such as those of housing, energy and food. No matter how much productivity is increased, developing a technological revolution and “sparing labor force”, the reduction of time, socially required for the production of goods and labor force, becomes harder and more marginal. This is the way the capitalist system enters a civilian, structural and organic crisis, as it is now. To go beyond the capital means to construct structures and superstructures of a new non-capitalist society based on a new way to produce, to work and to keep harmonious and friendly human social relations. It is difficult to have a successful revolution if not with the education of its agents, that is, the organized front people, parties and syndicates that will raise the social, political and cultural
