    Approved for public release; distribution is unlimited. Cross body thrusters permit a body of revolution Autonomous Underwater Vehicle to retain the energy efficiency of forward travel while increasing the ability to maneuver in confined areas such as harbors and piers. This maneuverability also permits more deliberate underwater surveys using a fixed, mounted forward and downward looking sonar. This work develops the necessary hydrodynamic coefficients, using methods applied to earlier ve...

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

    International Nuclear Information System (INIS)

    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.

    We present an analytical model of Doppler spectra in backscattering from arbitrary rough convex bodies of revolution rotating around their axes in the global Cartesian coordinate system. This analytical model is applied to analyse Doppler spectra in backscatter from two cones and two cylinders, as well as two ellipsoids of revolution. We numerically analyse the influences of attitude and geometry size of objects on Doppler spectra. The analytical model can give contribution of the surface roughness, attitude and geometry size of convex bodies of revolution to Doppler spectra and may contribute to laser Doppler velocimetry as well as ladar applications.

  7. Determination of Optimum Non-Slender Bodies of Revolution having Minimum Drag in Free Molecular Flow

    1971-10-01

    Full Text Available The problem of determining the body of revolution having minimum drag has been considered in the free molecular flow region under given integral constraints and in combination with the calculus of variations. It has been shown that for a given surface area or volume, the optimum shape is sharp nosed if diameter is prescribed and it is flat nosed if the length is prescribed. When the volume and thickness are known the optimum shape has cusp at the origin whereas if surface area and diameter are given the optimum body shape is independent of the value of k, a parameter dependent upon the temperature ratio and the speed ratio.

  8. Numerical simulation on drag reduction of revolution body through bionic riblet surface

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Numerical simulations of flow fields on the bionic riblet and the smooth revolution bodies were performed based on the SST k-ω turbulence model in order to explain the mechanisms of the skin friction drag reduction, base drag reduction on the riblet surface, and flow control behaviors of riblet surface near the wall. The simulation results show that the riblet surface arranged on the rearward of the revolution body can reduce the skin friction drag by 8.27%, the base drag by 9.91% and the total drag by 8.59% at Ma number 0.8. The riblet surface reduces the skin friction drag by reducing the velocity gradient and turbulent intensity, and reduces the base drag by weakening the pumping action on the dead water region which behind the body of revolution caused by the external flow. The flow control behavior on boundary layer shows that the riblet surface can cut the low-speed flow near the wall effectively, and restrain the low-speed flow concentrating in span direction, thus weaken the instability of the low speed steaks produced by turbulent flow bursting.

    NASA Langley's 13-inch Magnetic Suspension and Balance System (MSBS) has been used to conduct low-speed wind tunnel drag force measurements on a laminar-flow body-of-revolution free of support system interference, in order to verify the drag force measurement capabilities of the MSBS. The drag force calibrations and wind-on repeatability data obtained have verified the design capabilities for this system. A drag-prediction code has been used to assess the MSBS's usefulness in body drag estimation.

    2004-01-01

    Drag reduction characteristics of supercavitating body of revolution was researched numerically with a bubble two-phase flow model embodied in commercial CFD code Fluent 6.0.The work included the effects of body shape on drag coefficient and supercavity sizes; supercavity control; drag coefficient Cd as a function of cavitation number; and the effect of the ratio of length L to diameter D on drag reduction rate. Research on drag reduction mechanism of supercavitation shows that supercavitation can reduce not only the friction drag coefficient but also the pressure drag coefficient. There may be a best combination among body shape, the ratio L/D, cavitation number, engineering feasibility and so on, which makes the drag reduction ratehighest.

    2007-01-01

    Bionic non-smooth surfaces (BNSS) can reduce drag. Much attention has been paid to the mechanism of shear stress reduction by riblets. The mechanism of pressure force reduction by bionic non-smooth surfaces on bodies of revolution has not been, well investigated. In this work CFD simulation has revealed the mechanism of drag reduction by BNSS, which may work in three ways. First, BNSS on bodies of revolution may lower the surface velocity of the medium, which prevents the sudden speed up of air on the cross section. So the bottom pressure of the model would not be disturbed sharply, resulting in less energy loss and drag reduction. Second, the magnitude of vorticity induced by the bionic model becomes smaller because, due to the sculpturing, the growth of tiny air bubbles is avoided. Thus the large moment of inertia induced by large air bubble is reduced. The reduction of the vorticity could reduce the dissipation of the eddy. So the pressure force could also be reduced. Third, the thickness of the momentum layer on the model becomes less which, according to the relationship between the drag coefficient and the momentum thickness, reduces drag.

  12. Aerodynamic forces induced by controlled transitory flow on a body of revolution

    Science.gov (United States)

    Rinehart, Christopher S.

    The aerodynamic forces and moments on an axisymmetric body of revolution are controlled in a low-speed wind tunnel by induced local flow attachment. Control is effected by an array of aft-facing synthetic jets emanating from narrow, azimuthally segmented slots embedded within an axisymmetric backward facing step. The actuation results in a localized, segmented vectoring of the separated base flow along a rear Coanda surface and induced asymmetric aerodynamic forces and moments. The observed effects are investigated in both quasi-steady and transient states, with emphasis on parametric dependence. It is shown that the magnitude of the effected forces can be substantially increased by slight variations of the Coanda surface geometry. Force and velocity measurements are used to elucidate the mechanisms by which the synthetic jets produce asymmetric aerodynamic forces and moments, demonstrating a novel method to steer axisymmetric bodies during flight.

  13. INVESTIGATION OF VISCOUS FLOW FIELD AROUND AN APPENDED REVOLUTION BODY WITH GUIDE VANE PROPELLER

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    A RANS solver is presented to numerically simulate the viscous wake of an appended revolution body with guide vane propeller at the Reynolds number 107. The k-ε turbulence model together with wall function is used. The resulting finite difference equations are solved by SIMPLEC and ADI. The technique of rising up the bottom surface is presented to overcome radial contraction problem in Cartesian coordinate system. The three-dimensional body forces are separately adopted to model the affection of the guide vane and propeller. The detailed flow characteristics,especially the counter-swirl component generated by the guide vane in the propeller inflow, are numerically seized successfully. Compared with the experimental data, The computational axial velocity on the propeller disk plane comes up to engineering requirement.

  14. Coupled heat and mass transfer by natural convection from slender bodies of revolution in porous media

    International Nuclear Information System (INIS)

    This paper reports that analytical study of buoyancy induced heat and mass transfer from a slender body of revolution embedded in a saturated porous medium has been reported for two important cases: a paraboloid with constant temperature and concentration, a cylinder with linear temperature and concentration distribution. The governing parameters for the problem under study are the buoyancy ratio, N, and Lewis number, Le. Depending on the sign of the buoyancy ratio, the inclusion of a concentration gradient may assist or suppress the flow induced by thermal buoyancy. The Lewis number is found to have a much more pronounced effect on the concentration field than it does on the flow and temperature fields. The computed results have covered a wide range of the governing parameters, i.e., -1 < N < 10 and 0.1 < Le < 50

    1989-01-01

    Low speed wind tunnel drag force measurements were taken on a laminar flow body of revolution free of support interference. This body was tested at zero incidence in the NASA Langley 13 in. Magnetic Suspension and Balance System (MSBS). The primary objective of these tests was to substantiate the drag force measuring capabilities of the 13 in. MSBS. The drag force calibrations and wind-on repeatability data provide a means of assessing these capabilities. Additional investigations include: (1) the effects of fixing transition; (2) the effects of fins installed in the tail; and (3) surface flow visualization using both liquid crystals and oil flow. Also two simple drag prediction codes were used to assess their usefulness in estimating overall body drag.

    Marshall, F. J.; Deffenbaugh, F. D.

    1974-01-01

    A method is developed to determine the flow field of a body of revolution in separated flow. The computer was used to integrate various solutions and solution properties of the sub-flow fields which made up the entire flow field without resorting to a finite difference solution to the complete Navier-Stokes equations. The technique entails the use of the unsteady cross flow analogy and a new solution to the two-dimensional unsteady separated flow problem based upon an unsteady, discrete-vorticity wake. Data for the forces and moments on aerodynamic bodies at low speeds and high angle of attack (outside the range of linear inviscid theories) such that the flow is substantially separated are produced which compare well with experimental data. In addition, three dimensional steady separated regions and wake vortex patterns are determined. The computer program developed to perform the numerical calculations is described.

  18. Moralized Hygiene and Nationalized Body: Anti-Cigarette Campaigns in China on the Eve of the 1911 Revolution

    Directory of Open Access Journals (Sweden)

    Wennan Liu

    2013-03-01

    Full Text Available Western knowledge about the injurious effects of cigarette smoking on smokers’ health appeared in the late nineteenth century and was shaped by both the Christian temperance movement and scientific developments in chemistry and physiology. Along with the increasing import of cigarettes into China, this new knowledge entered China through translations published at the turn of the twentieth century. It was reinterpreted and modified to dissuade the Chinese people from smoking cigarettes in two anti-cigarette campaigns: one launched by a former American missionary, Edward Thwing, in Tianjin, and a second by progressive social elites in Shanghai on the eve of the 1911 Revolution. By examining the rhetoric and practice of the campaigns, I argue that the discourse of hygiene they deployed moralized the individual habit of cigarette smoking as undermining national strength and endangering the future of the Chinese nation, thus helping to construct the idea of a nationalized body at this highly politically charged moment.

  19. Transitory Aerodynamic Forces on a Body of Revolution using Synthetic Jet Actuation

    Science.gov (United States)

    Rinehart, Christopher; McMichael, James; Glezer, Ari

    2002-11-01

    The aerodynamic forces and moments on axisymmetric bodies at subsonic speeds are controlled by exploiting local flow attachment using fluidic (synthetic jet) actuation and thereby altering the apparent aerodynamic shape of the surface. Control is effected upstream of the base of the body by an azimuthal array of individually-controlled, aft-facing synthetic jets emanating along an azimuthal Coanda surface. Actuation produces asymmetric aerodynamic forces and moments, with ratios of lift to average jet momentum approaching values typical of conventional jet-based circulation control on two-dimensional airfoils. Momentary forces are achieved using transient (pulsed) actuation and are accompanied by the formation and shedding of vorticity concentrations as a precursor to the turning of the outer flow into the wake region.

    In this work, a hybrid formulation is established for bodies of revolution, based on the equation of Fourier series for the discontinuous finite element method, analogous to the one that exists in the classical finite element method. Furthermore, a methodology to analyse the prevention of fragile fracture in pressure vessel of pressurized water reactors is presented. The results obtained suggest that careful analysis must be made for non symmetric refrigeration. (author)

    International Nuclear Information System (INIS)

    The problem of wave scattering by a magnetodielectric body of revolution is solved. A new version of modified method of discrete sources (MMDS) is offered. This version of MMDS is suitable both for strongly elongated or strongly flattened bodies and toroidal bodies. The method is tested by verification of the optical theorem and calculation of the residual of boundary condition at the scatterer surface. The angle dependences of the pattern for various geometries of the body cross-section are obtained. The check of the Ufimtsev theorem for flattened Chebyshev particle is fulfiled. -- Highlights: ► The new version of the modified method of discrete sources is developed. ► The method is applied to elongated, flattened and toroidal bodies of revolution. ► The effective algorithm for construction of the auxiliary surfaces is offered. ► Comparison of the results obtained by MMDS and pattern equation method is made. ► The advantages of the new version compared with the standard MMDS are shown. ► The check of the Ufimtsev theorem is fulfilled.

    The third phase of the development of the computer codes for scattering by coated bodies that has been part of an ongoing effort in the Electromagnetics Laboratory of the Electrical Engineering and Computer Science Department at the University of Illinois at Chicago is described. The work reported discusses the analytical and numerical results for the scattering of an obliquely incident plane wave by impedance bodies of revolution with phi variation of the surface impedance. Integral equation formulation of the problem is considered. All three types of integral equations, electric field, magnetic field, and combined field, are considered. These equations are solved numerically via the method of moments with parametric elements. Both TE and TM polarization of the incident plane wave are considered. The surface impedance is allowed to vary along both the profile of the scatterer and in the phi direction. Computer code developed for this purpose determines the electric surface current as well as the bistatic radar cross section. The results obtained with this code were validated by comparing the results with available results for specific scatterers such as the perfectly conducting sphere. Results for the cone-sphere and cone-cylinder-sphere for the case of an axially incident plane were validated by comparing the results with the results with those obtained in the first phase of this project. Results for body of revolution scatterers with an abrupt change in the surface impedance along both the profile of the scatterer and the phi direction are presented.

    1988-01-01

    Low-speed wind tunnel drag force measurements were taken on a laminar flow body of revolution free of support interference. This body was tested at zero incidence in the NASA Langley 13 inch Magnetic Suspension and Balance System (MSBS). The primary objective of these tests was to substantiate the drag force measuring capabilities of the 13 inch MSBS. A secondary objective was to obtain support interference free drag measurements on an axisymmetric body of interest. Both objectives were met. The drag force calibrations and wind-on repeatability data provide a means of assessing the drag force measuring capabilities of the 13 inch MSBS. The measured drag coefficients for this body are of interest to researchers actively involved in designing minimum drag fuselage shapes. Additional investigations included: the effects of fixing transition; the effects of fins installed in the tail; surface flow visualizations using both liquid crystals and oil flow; and base pressure measurements using a one-channel telemetry system. Two drag prediction codes were used to assess their usefulness in estimating overall body drag. These theoretical results did not compare well with the measured values because of the following: incorrect or non-existent modeling of a laminar separation bubble on the body and incorrect of non-existent estimates of base pressure drag.

    Experiments are conducted for the characteristics of both body and wake-generated internal waves due to a revolution body(aspect ratio 7:1) in a stratified fluid with a pycnocline where the revolution body is horizontally towed in forward and backward ways.Results show that the body-generated internal waves are a type of stationary multiple-mode Lee wave structures,and the wake-generated internal waves are a type of non-stationary quasi-Lee structures produced by the large-scale coherent structure in the turbulent wake acting as a moving excitation with respect to the towed revolution body.The transition between Lee and quasi-Lee waves occurs at a critical Froude number Fr_c which is shown to be linearly dependent on the aspect ratios of the revolution bodies where the wave patterns for Fr Fr_c are dominated by Lee waves,whereas the wave patterns for Fr Fr_c are dominated by quasi-Lee waves, Fr is the Froude number for the characteristic diameter of the revolution body.For the quasi-Lee waves,the dimensionless peak-topeak amplitudes linearly increase with Fr and the Froude numbers relative to the correlation velocities remain at a relatively constant value of approximately 0.8 regardless of the aspect ratios.Moreover,the head and the tail shapes of the revolution body have no remarkable influence on the critical Froude number Fr_c,as well as both the Froude numbers relative to the correlation velocities and the dimensionless peak-to-peak amplitudes of the quasi-Lee waves.%在具有连续密度跃层的分层流体中,对长径比为7:1的回转体在迎水和背水运动下激发体积效应与尾迹效应内波特性开展了系列实验.结果表明,体积效应激发内波属于一种相对于回转体定常的多模态Lee波结构,而尾迹效应激发主控内波为相对于回转体非定常的拟Lee波结构,这是一类由湍流尾迹中大尺度相干结构作为移动源激发的内波结构,在Lee波与拟Lee波之间存在

    We present an algorithm for extracting the axis of revolution from the implicit equation of an algebraic surface of revolution based on three distinct computational methods: factoring the highest order form into quadrics, contracting the tensor of the highest order form, and using univariate resultants and gcds. We compare and contrast the advantages and disadvantages of each of these three techniques and we derive conditions under which each technique is most appropriate. In addition, we provide several necessary conditions for an implicit algebraic equation to represent a surface of revolution. PMID:26561460

    Report presents the results of an investigation conducted to determine the effects of heat transfer on boundary-layer transition on a parabolic body of revolution (NACA rm-10 without fins) at Mach number of 1.61 and over a Reynolds number range from 2.5 x 10(6) to 35 x 10(6). The maximum cooling of the model used in these tests corresponded to a temperature ratio (ratio of model-surface temperature to free-stream temperature) of 1.12, a value somewhat higher than the theoretical value required for infinite boundary-layer stability at this Mach number. The maximum heating corresponded to a temperature ratio of about 1.85. Included in the investigation was a study of the effects of surface irregularities and disturbances generated in the airstream on the ability of heat transfer to influence boundary-layer transition.

    With a focus on the problem of bionic jet drag reduction , a bionic jet surface model is presented by using the jet flow of shark cheeks as the prototype .Based on the orthogonal test design method , this paper goes into detail about numerical simulations by making a comparison between bodies of revolution of a bionic annular jet flow sur -face ( BRBAJFS ) and smooth bodies of revolution with the SST k-ωturbulence model .The results prove that BRBAJFS has obvious drag-reduction and energy-saving effects .The highest energy saving efficiency can be 262 and the corresponding rate of drag reduction is 27.74%.The jet velocity has the most important impact on energy saving efficiency and it has a linear relation with the energy saving efficiency , i.e., the energy saving efficiency will decrease with an increase in the jet velocity .Furthermore, the position of the jet hole has the greatest impact on the total resistance .When the jet hole is far away from the bottom of the bodies of revolution , the drag reduction effi-ciency will increase and BRBAJFS decreases the viscous friction resistance by decreasing the velocity gradient of the wall and increasing the area of counterblows .There can also be a decrease in the pressure drag resulting from the jet fluid complementing the bottom of the bodies of revolution fluid .%针对仿生射流表面减阻问题,以鲨鱼鳃部射流为原型,建立仿生射流表面模型,采用正交试验设计法,利用SST k-ω湍流模型对仿生环形射流表面旋成体与光滑旋成体进行数值模拟。结果表明:旋成体环形射流表面具有减阻节能效果,最高节能效率达262,此时的减阻率为27.74%;射流速度对节能效率影响最大,射流速度与节能效率呈线性关系,随着射流速度增大,节能效率减小,射流孔位置对总阻力的影响最大,随着射流孔远离旋成体底部,减阻率增大。旋成体环形射流表面通过减小壁面的速度梯

    When main dimensions and cruising speed have been predefined, how to get an axisymmetric revolution body with minimal drag force at the conceptual design stage of autonomous underwater vehicles ( AUVs) has been a problem. This paper analyzed drag force of Myring shaped axisymmetric revolution body moving underwater in a di-rect route, at constant speed, by CFD method and compared with the experiment value to check the veracity. 2D or 3D mesh, standard or enhanced wall treatment function was adopted respectively to figure out the accuracy and effi-ciency. And on this basis, the change law of drag when changing merely length and shape of the nose or tail was discussed. Based on multi-island and genetic algorithm ( MIGA ) , an optimization platform was constructed with EXCEL, ICEM and FLUENT to search for the best axisymmetric revolution body with minimal drag force at differ-ent speed when volume is predefined. This is a good reference for calculating and minimizing total drag of AUVs.%在水下智能机器人( AUV)方案设计阶段,针对如何在主尺度和巡航速度确定的前提下得到直航阻力最小的回转体形状这个问题,以Myring型回转体为研究对象,利用计算流体力学( CFD)方法计算其在水中做匀速直航运动时的阻力并与试验值比较以验证准确性。分别对二维和三维2种网格形式,标准和加强2种壁面函数的计算精度和计算效率进行了对比,并在此基础上探讨单独改变艏部或艉部形状时阻力的变化规律。再利用EXCEL、ICEM、FLUENT建立优化平台,基于多岛遗传算法在限制条件范围内对Myring型回转体参数进行全局寻优,寻找不同流速时阻力最小的Myring型回转体,为AUV设计阶段的阻力性能预报和艇型优化提供参考。

    Full Text Available Phenomenon of transdisciplinarity was put into the fore of analysis rather recently. In the article an attempt is made to find out whether it is possible to attribute this phenomenon not only to a science (or even non-classical post-non-classical of the 21st century, or we have here the case where some scientific realities come to the attention of researchers with certain delay and has its value for the culture in general? It is possible to judge even the emergence of a kind of cognitive revolution affecting both science culture. We need to find out what is meant by a transdisciplinarity, and how it differs from the inter- or multiransdisciplinarity. In the study the method of historical reconstruction, combining elements of presentism and antiqurism, was implemented. This method allows us to interpret historical events in the context of a specific level of knowledge, and at the same time to evaluate them in terms of modern ideas related to transdisciplinarity, inter- and multidisciplinarity. System-structural method , focused on an integrated analysis of the dynamics of development of cognitive processes in culture was implied as well, and the method of comparative analysis, which is aimed at comparing different but conceptually similar processes in various areas of conceptual art practice. It is in the framework of (disciplinary based paradigm adopted a tacit agreement among scientists about the validity and effectiveness of research methods and techniques of inquiry. Within the (disciplinary based paradigm, which presupposes certain fundamental principles, goals, and certain values shared by the scientific community, the novel sprouts of radical ideas once emerge. The scientific revolution here means a radical revision of the admissibility of accepted and proven methods, goals and values that are common to the members of the scientific community.

    1987-01-01

    An experimental investigation was conducted in the slotted test section of the 0.1-scale model of the proposed Altitude Wind Tunnel to evaluate wall interference effects at tunnel Mach numbers from 0.70 to 0.95 on bodies of revolution with blockage rates of 0.43, 3, 6, and 12 percent. The amount of flow that had to be removed from the plenum chamber (which surrounded the slotted test section) by the plenum evacuation system (PES) to eliminate wall interference effects was determined. The effectiveness of tunnel reentry flaps in removing flow from the plenum chamber was examined. The 0.43-percent blockage model was the only one free of wall interference effects with no PES flow. Surface pressures on the forward part of the other models were greater than interference-free results and were not influenced by PES flow. Interference-free results were achieved on the aft part of the 3- and 6-percent blockage models with the proper amount of PES flow. The required PES flow was substantially reduced by opening the reentry flaps.

    Current human activities undoubtedly impact natural ecosystems. However, the influence of Homo sapiens on living organisms must have also occurred in the past. Certain genomic characteristics of prokaryotes can be used to study the impact of ancient human activities on microorganisms. By analyzing DNA sequence similarity features of transposable elements, dramatic genomic changes have been identified in bacteria that are associated with large and stable human communities, agriculture and animal domestication: three features unequivocally linked to the Neolithic revolution. It is hypothesized that bacteria specialized in human-associated niches underwent an intense transformation after the social and demographic changes that took place with the first Neolithic settlements. These genomic changes are absent in related species that are not specialized in humans. PMID:16569502

  19. Silicon: Child and Progenitor of Revolution

    Cahn, R. W.

    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.

    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...

    Bai, ZhengFeng; Zhao, Yang; Wang, XingGui

    2013-08-01

    In this work, the prediction of wear for revolute joint with clearance in multibody systems is investigated using a computational methodology. The contact model in clearance joint is established using a new hybrid nonlinear contact force model and the friction effect is considered by using a modified Coulomb friction model. The dynamics model of multibody system with clearance is established using dynamic segmentation modeling method and the computational process for wear analysis of clearance joint in multibody systems is presented. The main computational process for wear analysis of clearance joint includes two steps, which are dynamics analysis and wear analysis. The dynamics simulation of multibody system with revolute clearance joint is carried out and the contact forces are drawn and used to calculate the wear amount of revolute clearance joint based on the Archard's wear model. Finally, a four-bar multibody mechanical system with revolute clearance joint is used as numerical example application to perform the simulation and show the dynamics responses and wear characteristics of multibody systems with revolute clearance joint. The main results of this work indicate that the contact between the joint elements is wider and more frequent in some specific regions and the wear phenomenon is not regular around the joint surface, which causes the clearance size increase non-regularly after clearance joint wear. This work presents an effective method to predict wear of revolute joint with clearance in multibody systems.

    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. PMID:26173215

    A large deflection elastic-plastic analysis is presented applicable to orthotropic axisymmetric plates and shells of revolution subjected to monotonic and cyclic loading conditions. The analysis is based on the finite-element method. It employs a new higher order, fully compatible, doubly curved orthotropic shell-of-revolution element using cubic Hermitian expansions for both meridional and normal displacements. Both perfectly plastic and strain hardening behavior are considered. Strain hardening is incorporated through use of the Prager-Ziegler kinematic hardening theory, which predicts an ideal Bauschinger effect. Numerous sample problems involving monotonic and cyclic loading conditions are analyzed.

    Full Text Available This paper proposed to determine the Cartesian stiffness matrix and angular deflection analysis of revolute manipulator. The selected manipulator has rigid fixed link, two movable links and two rotary joints with joint stiffness coefficients are taken into account. The kinematic model of revolute joint manipulator has considered as a planar kinematic chain, which is composed by rigid fixed link and two revolute joints with clearance and deformable elements. The calculation of stiffness matrix depends on Jacobian matrix and change of configuration. The rotational joints are modeled as torsion springs with the same stiffness constant. The relative angular deflections are proportional to the actuated torques taken into account. The subject of this paper has to describe a method for stiffness analysis of serial manipulator. In the present work is to derive the stiffness matrix and angular deflection equations in the Robotic manipulator under the consideration of two-link optimum geometry model for rotary joint manipulator. The stiffness values are measured by displacements of its revolute links loaded by force.

    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.

  18. 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.

  19. Thermoelastic stability of bimetallic shallow shells of revolution

    OpenAIRE

    Batista, Milan; Kosel, Franc

    2015-01-01

    This article considers the thermoelastic stability of bimetallic shallow shells of revolution. Basic equations are derived from Reissner's non-linear theory of shells by assuming that deformations and rotations are small and that materials are linear elastic. The equations are further specialized for the case of a closed spherical cup. For this case the perturbated initial state is considered and it is shown that only in the cases when the cup edge is free or simply supported buckling under h...

    Dragovan, M

    1988-10-01

    A procedure for cutting surfaces of revolution using a numerically controlled milling machine is described. The procedure differs from conventional techniques in that the curve to be cut is approximated by a circular arc. The errors introduced by the approximation scheme are less than the machining errors. This procedure can be implemented on any machine capable of cutting an arbitrary radius circular arc. It also reduces the number of programming instructions by a factor of ~50. PMID:20539518

  7. The Media and the Making of the 2011 Egyptian Revolution

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available The outbreak of the Hungarian revolution in 1956 brought forth solidarity movements fromHungarian émigrés all over the world. In Argentina, the response was overwhelming. Hungarianémigré organizations formed a "Comité de Ayuda pro Hungría Libre" (Aid Committee for a FreeHungary, coordinating the strategies and actions aimed at providing moral and material supportfor the revolution. Supplementing and aiding these actions were those of the Argentinegovernment and population at large. The government named a special commission for refugees;and there was a tremendous outpour of sympathy and material support for Hungarians amongArgentines, with major press coverage for months to come. Of special importance is the literaryand press output following the revolution. These actions provoked fear and rejection from theEmbassy of the People's Republic of Hungary, and it accused the Argentine government of openlysiding with the émigrés. Upon the Hungarian Foreign Ministry's instructions, the Embassystrongly intensified the espionage on the émigré institutions and its prominent members for years.Relations between émigré organizations and the Hungarian Government remained nonexistent orstrained until the lifting of the Iron Curtain in 1990.

  9. Visions of Revolutions: Microphysics and Cosmophysics in the 1930s

    CERN Document Server

    Kragh, Helge

    2011-01-01

    By 1930, at a time when the new physics based on relativity and quantum theory had reached a state of consolidation, problems of a foundational kind began to abound. Physicists began to speak of a new "crisis" and envisage a forthcoming "revolution" of a scale similar to the one in the mid-1920s. The perceived crisis was an issue not only in microphysics but also in cosmology, where it resulted in ambitious cosmophysical theories that transcended the ordinary methods of physics. The uncertain cognitive situation was, in some circles, associated to the uncertain political and moral situation. Did the problems of foundational physics demand a revolution in thinking that somehow paralleled the political revolutions of the time? I argue that although such ideas were indeed discussed in the 1930s, they were more rhetoric than reality. With the benefit of hindsight one can see that the perceived crisis was only temporary and not significantly related to social or ideological developments in the decade.

    Science.gov (United States)

    Knoche, H. G.; Schamel, W.; Esch, H.; Schneider, W.

    Systematic wind tunnel tests for a series of missile bodies were conducted by varying cross section shape and body length in the subsonic Mach number range and up to high angles of attack. Tests with a body-wing and a body-tail configuration were performed in order to investigate the body-wing and body-tail interference for bodies of revolution and bodies with rectangular cross section. At a constant angle of attack, the boxlike body supplies far more normal force than the body of revolution with the same cross section area. The boxlike body shows strong coupling effects between the pitch, yaw and roll. The interference effect of the wing and body can be described well, in the case of boxlike bodies with wings in high or low wing positions, by the known slender body interference factors, assuming the width of the box to be the diameter of an equivalent, axially symetrical body.

  17. Transient dynamic and inelastic analysis of shells of revolution

    International Nuclear Information System (INIS)

    Advances in the limits of structural use in the aerospace and nuclear power industries over the past years have increased the requirements upon the applicable analytical computer programs to include accurate capabilities for inelastic and transient dynamic analyses. In many minds, however, this advanced capability is unequivocally linked with the large scale, general purpose, finite element programs. This idea is also combined with the view that, therefore, such analyses are prohibitively expensive and should be relegated to the 'last resort' classification. While this, in the general sense, may indeed be the case, if however, the user needs only to analyze structures falling into limited categories, he may find that a variety of smaller special purpose programs are available, which do not put an undue strain upon his resources. One such structural category is shells of revolution. This survey of programs will concentrate upon the analytical tools which have been developed predominantly for shells of revolution. The survey will be subdivided into three parts: a) consideration of programs for transient dynamic analysis, b) consideration of programs for inelastic analysis, and finally, c) consideration of programs capable of dynamic plasticity analysis. In each part, programs based upon finite difference, finite element, and numerical integration methods will be considered. The programs will be compared on the basis of analytical capabilities, and ease of idealization and use. In each part of the survey sample problems will be utilized to exemplify the state-of-the-art.

  10. Commercial use of hydrogen is a revolution

    International Nuclear Information System (INIS)

    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 to be constantly amazed by the dots that the cultural historian connects, by the different terrains that he leads us through, and by the expansive vistas that he brings into focus. Students interested in almost any aspect of modern and contemporary Chinese culture (from film to fiction to music to dance to bodybuilding will appreciate the wealth of materials and references contained in these two volumes. 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.

  14. Creep deformations of shells of revolution under asymmetrical loading

    International Nuclear Information System (INIS)

    The numerical analysis of creep deformations of shells of revolution under unsymmetrical loads is described with application to a cylindrical shell. The analytical formulation of the creep of axisymmetric undergoing unsymmetrical deformations is developed for two hardening laws: the time hardening law and the strain hardening law. The method is based on the creep power law, and on the assumption of plane stress condition and the Euler-Bernoulli hypothesis used in the ordinary thin shell theory. The basic differential equations derived for incremental values with respect to time are numerically solved by a finite difference method and the solutions at any time are obtained by integration of the incremental values. In conclusion the computer programs are developed which can be used to predict the creep deformations of arbitrary axisymmetrical shells. As a numerical example the creep deformation of cylindrical shell of importance in practical use is treated, and the variations of displacements and internal forces with the lapse of time are discussed

    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.

    Full Text Available The "Age of Revolutions" paradigm, pioneered by R.R. Palmer and Eric Hobsbawm, has been enormously influential, especially in the study of the Atlantic World c. 1750-1850. Yet it was developed without reference to the Luso-Brazilian World (and a mere passing reference to Spanish America. This essay explores the utility of the "Age of Revolutions" framework for the study of the Luso-Atlantic and suggests that Luso-Brazilian History can enrich, and modify, the prevailing understanding of the "Age of Revolutions".

    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...

The author states that the colour revolutions threaten the normal existence of the country or several countries. The conclusion is made that the colour revolutions must be counteracted by criminallegal means. The article states the absence of norms in the existing criminal legislation which would impose criminal liability on organizers incendiaries and participants of colour revolutions. It is proposed to supplement the existing criminal law with the norm stipulating the liability for such deeds and to insert this norm into Art. 34 ldquoCrimes against peace and security of humanityrdquo thus equating organization preparation and implementing colour revolutions with planning preparation launching and conducting an aggressive war Art. 353 of the Russian Criminal Code. Scientific novelty basing on the existing legal norms modern politological and juridical scientific literature a conclusion is made that the colour revolutions are based on the abuse of law.

    Full Text Available By the late 1980s, Ceaușescu had transformed Romania into a police state. The uprising from december 1989 that led to Ceaușescu’s downfall began with some incidents in Timisoara on 16 of December. The demonstrations spread to Bucharest, and further to others cities of Romania. We aimed to treat in this paper the Romanian Revolution of 1989, a mixture of spontaneous general uprising and conspiracy against Ceaușescu organized by reform communists and disaffected elements of the Securitate and army. The perspective from which we have chosen to look at the event (and also to the road to the shock of december 1989 is through Dumitru Popescu’s memoirs. Dumitru Popescu, ex- vice president of the State Committee for Culture and Art and President of the Council of Socialist Culture and Education, was one of the creators of the Ceausescu’s ideology. He graduate the Party School of Social Sciences „A.A. Jdanov“ in 1957- an ideological training institute where besides the unconditional commitment to the party some cultural training was required as well.

  9. Voigt's transformations and the beginning of the relativistic revolution

    In 1887 W. Voigt published a paper on the Doppler effect, which marked the birth of the relativistic revolution. In his paper Voigt derived a set of spacetime transformations by demanding covariance to the homogeneous wave equation in inertial frames, and this was an application of the first postulate of special relativity. Voigt assumed in his derivation the invariance of the speed of light in inertial frames, and this is the second postulate of special relativity. He then applied the postulates of special relativity to the wave equation 18 years before Einstein explicitly enunciated these postulates. Voigt's transformations questioned the Newtonian notion of absolute time for the first time in physics by suggesting that the absolute time should be replaced by the non-absolute time $t'=t-vx/c^2$. Unfortunately, Voigt's 1887 paper was not appreciated by most physicists of that time. Voigt's transformations do not form a group and are an example of the conformal symmetry of spacetime. In the present paper we 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.

    Full Text Available Modernity changed the community interests; it idealized individuality and liberal democracy, and based its main aim on pushing religion to the outskirts of human life. Western Christianity adjusted to modernity to justify the developments while Islam accepted it only to the extent of its capacity to authenticate the realities stated by the Qur’an. Orientalism, Occidentalism, and Islamism play impressive role in a variety of contexts today. Occidentalism in its popular variety helps to reinforce the identities. This study considers the power relationship between people and cultures. The roles and the identities are changing throughout history. Nowadays Islamic culture is one of popular subjects to study on. So, the Muslim world and revival of Islamic culture are the beginning of Occidentalism. Occidentalism is developed in the Orient in order to study the West from a non-Western World point of view. It can be referred as revival of identity (for isteghrab in Arab world by Hasan Hanafi or Talibanian or ISIS Occidentalists movements which stand for empowering Arab culture, Wahhabism or Salafism. All are revivalist movements to rapture Islamism as an ideology. This article tries to focus on the concept of Occidentalism in Iran after Iran Cultural Revolution.

    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.

    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.

  15. [Consumption of alcoholic beverages: cultural revolution is necessary].

    2015-11-01

    Significant investment in advertising has been made to promote the consumption of alcoholic beverages, but only 0.5% of the GDP is allocated for preventing alcohol use. Although available evidence clearly demonstrates a causal relationship between ethanol and cancer, the perception of risk in the general population remains extremely low. This is partly due to the fact that alcohol consumption is considered as a "normal" habit in our society, mostly as a consequence of the lack of appropriate information. It should also be emphasized the lack of a common language within the healthcare community, in that too often alcohol is identified as a food or a preservative. The fourth edition of the RDA represents a true cultural revolution as it identifies alcohol consumption as a risk, regardless of the amount consumed. Recommended dosages are defined as low-risk dosages. It would be appropriate to correctly apply the Law 125/2001, which provides for inclusion of alcoholism in university education programs.

Mushroom can serve as food, tonic, and as medicine thus make people healthier, fitter and happier. They have a cracking potential for generating great socioeconomic impact in human welfare at local, national and international level. With the help of allied mushroom farming we can easily tackle the problem of food for growing world population; reduce environmental pollution by bioconversion of huge organic wastes into mushrooms; recycle huge quantity of organic wastes to mushroom crops, biofertilizers, and biogas; restore damaged environment by mushroom mycelia through mycoforestry, mycoremediation, mycofiltration and mycopesticides in a zero emission fashion. They can be used to degrade radioactive industrial biocide wastes in an eco-friendly fashion. Since mushroom cultivation is an indoor agribusiness, it could have great economic impact by generating employment, income and functional food requirements for rural people especially in developing countries. How far mushroom cultivation can meet the functional food requirements; address the domestic food challenges, rising food prices and crisis vis a vis environmental sustainability will be thrust areas of this communication.

    Full Text Available The paper provides an overview of the so-called information revolutions, with a special emphasis on the spreading of communication channels. The notion 'information revolution' is used conditionally – not in the sense of disruptive changes in communication models, but in the sense of expansion of communication possibilities. The revolutions were identified using Irving E. Fang's criteria. He defined six revolutions: writing, printing, mass media, using media for entertainment, the 'toolshed' (now called 'home', and the Information Highway. The paper presents the basic media in each of the revolutions, questions the very current issues of convergence (as some modern scholars consider the term convergence to be more appropriate than the term revolution, and divergence of media, and special attention is paid to the social context that lead to particular revolutions. The central conclusion is that information revolutions were not the time of replacing the old media with the new, but the times of condensation of communication possibilities. During those times the new media joined the existing types, not replacing them but co-existing. They faded out gradually or disappeared only over extended periods of time. Key-words: information revolutions, media, convergence, divergence, communication.

    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.Keywords: Martin Amis, sexual revolution, feminism, satire, gender, revolution

    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...

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.

    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 tauschi , 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 wel-known Green Revolution al ele Rht-D1b, Hapl VII (an al ele 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.

    2016-01-01

    This paper develops an agent-based computational model of violent political revolutions in which a subjugated population of citizens and an armed revolutionary organisation attempt to overthrow a central authority and its loyal forces. The model replicates several patterns of rebellion consistent with major historical revolutions, and provides an explanation for the multiplicity of outcomes that can arise from an uprising. The relevance of the heterogeneity of scenarios predicted by the model can be understood by considering the recent experience of the Arab Spring involving several rebellions that arose in an apparently similar way, but resulted in completely different political outcomes: the successful revolution in Tunisia, the failed protests in Saudi Arabia and Bahrain, and civil war in Syria and Libya.

    Full Text Available In this paper the space intersecting curve between two surfaces of revolution with parallel axes of surfaces have been determined. Two mathematical models for determination of intersecting curve between two surfaces of revolution have been formed: auxiliary planes have been used in the first mathematical model and auxiliary spheres have been used in the second model (Obradović 2000. In the first case each auxiliary plane intersected with each surface of revolution on circle and two points of intersecting curve are obtained as intersecting points between these two circles. In the second case centres of two locks of auxiliary spheres are put on axes of surfaces of revolution (centre of first lock is on axis of the first surface of revolution and centre of second lock is on axis of the second surface of revolution on saine z coordinate (when axes of surfaces of revolution are parallel with z axis of coordinate system. First lock sphere intersects the first surface of revolution on w1 parallels and second lock corresponding sphere intersects the second surface of revolution on w2 circles. It is possible to find a relationship that for selected radius of the first lock sphere can determine the radius of second lock sphere and real points of intersecting curve have been determined by use of these two spheres. The points of intersecting curve between two surfaces of revolution are obtained by intersection between w1 circles from the first surface with w2 circles from the second surface (Obradović 2000.

Today, a century after the 1911Revolution, we need to look at this event from a macro perspective, on a scale of centuries and millennia, in order to fi x its place in Chinese history. In other words, we need to reexamine the signifi...

    There was a time, not too long ago, when the typewriter and notebook ruled, and the computer as an everyday tool was simply a vision. Revolution in the Valley traces this vision back to its earliest roots: the hallways and backrooms of Apple, where the groundbreaking Macintosh computer was born. The book traces the development of the Macintosh, from its inception as an underground skunkworks project in 1979 to its triumphant introduction in 1984 and beyond. The stories in Revolution in the Valley come on extremely good authority. That's because author Andy Hertzfeld was a core member of the

    2008-01-01

    Revolution is an event that had taken place in many countries in the 20th century. Revolution was not only imagined in Western historical writing as a radical change of social life, but also perceived as representing a return to the old form of social rule in the end. The Chinese ideas of revolution in the 20th century evolved from the traditional idea that the change of dynasties was due to the change of mandate. The modern Chinese idea of revolution also incorporated the European idea that revolution would lead to a higher form of social development. The interpretation of the aim of Chinese revolution in the 20th century China shows that Chinese theorists had a misunderstanding for a long time regarding revolution as representing an ultimate social state and not as a means to achieve political modernization. A theoretical rethinking of the concept after the Cultural Revolution has resulted in an advance in China's social evolution.%革命是20世纪具有世界历史普遍意义的事件.革命在西方历史编纂中既被想象为是社会发展的突变和质变,也被想象为会终结于向旧制度的某种形式的回归.20世纪中国的革命理念是在传统天命论王朝更迭观念的基础上,吸收了关于革命会通向社会演化更高阶段的欧洲理论而发展出来的.回顾20世纪中国思想界对中国革命所要达到的目的的认知可见:思想界曾一度在把革命看作是代表一种终极完善政治状态,还是仅是实现现代化的手段途径上存在误区.文革后在理论上的拨乱反正,促成了中国历史的真正飞跃.

  2. Feeding Revolution: The Black Panther Party and the Politics of Food

    2014-02-01

    Full Text Available This chapter examines the role of food in the symbolic politics and practical agenda of the Black Panther Party (BPP, founded in the late 1960s in Oakland, California.  Situating hunger and the politics of food at the center of drives for racial justice, it argues that the BPP’s anti-hunger efforts and food-centered campaigns were driven by an implicit understanding of the power of food in battles over racialized definitions of personhood, a forum for both enforcing and resisting hegemonic authority.  From this vantage, the Panthers and their allies in the East Bay community utilized the Party’s popular food programs, specifically its Free Breakfast for School Children Program, as staging grounds to prepare for a revolutionary overthrow of the socio-economic order.  In addition to strengthening the physical bodies of African Americans to ensure their “survival pending revolution,” the food programs served a deeper organizing function by encouraging community members to come together to meet an immediate, practical need and, in doing so, to visualize themselves as part of a larger movement for change.  The Panthers’ subsequent demands for consumer rights and calls for conscientious consumption (both as purchasers and eaters of food highlighted the role of food politics in perpetuating racial injustice while demonstrating the capacity for food-related protest to challenge structures of hunger and patterns of widespread malnourishment.

    Full Text Available The article is an attempt to analyze and provide scientific assessment of the events of the political history of Russia in the early XX century, whiсh took place, in the opinion of the authors, under influence by a number of objective factors. The regional specific of the article (in the example of the southern districts of the Saratov province and Cossack areas of the Volga-Don interfluve aims to search for the general laws of the formation of social and political movements that aim to change the existing system in Russia during the First Russian Revolution. The authors attempt to systematize the vast amount of material, which allows to identify the main causes of the mass revolutionary movement, character and social composition of the political groups and their impact on changes in the socio-political life of the region. Particular attention is paid to the activities of the Russian Social-Democratic Party, which position was strengthened by difficult economic plight of the workers and repressive government policies aimed at curbing the revolutionary movement. In modern conditions of social and political instability in many regions of the world, provoked by political technologies of "orange" revolution, it is highly relevant to study history of the First Russian Revolution of 1905-1907, which the 110th anniversary passed unnoticed. Despite the defeat, the revolution was of great importance for the emergence of civil society in Russia. As a result of mass protests of various social strata of Russian society, the first steps towards the formation of constitutionalism and parliamentarianism in Russia were made. In predominantly peasant Volga-Don region with high industrialized city Tsaritsyn all the contradictions of feudal-capitalist Russia's reality were focused and were clearly manifested, that turned into a powerful social explosion, which became the preparation of the 1917 Revolution.

  11. Analysis and design of planar multibody systems with revolute joint wear

    Science.gov (United States)

    Mukras, Saad M.

    Wear prediction on the components of a mechanical system without considering the system as a whole will, in most cases, lead to inaccurate predictions. This is because the wear is directly affected by the system dynamics which evolves simultaneously with the wear. In addition, the contact condition (regions of contact for the wearing bodies) also depends on the system dynamics and, in most cases, can only be determined in a multibody dynamics framework. In this work, a procedure to analyze planar multibody systems in which wear is present at one or more revolute joints is presented. The analysis involves modeling multibody systems with revolute joints that consist of clearance. Wear can then be incorporated into the system dynamic analysis by allowing the size and shape of the clearance to evolve as dictated by wear. An iterative wear prediction procedure based on the Archard's wear model is used to compute the wear as a function of the evolving dynamics and tribological data. In this framework, two procedures for the analysis of planar multibody systems with joint wear are developed. In the first procedure contact force at the concerned joint is determined using a contact force law and the wear prediction is based on the finite element method. In the second procedure, contact force determination and the wear prediction are based on the elastic foundation model. The two procedures are validated by comparing the wear predictions with wear on an experimental slider-crank mechanism. The experimental slider-crank is also used as a reference to assess the performance of the two models. It turns out that the procedure based on the finite element method provides reasonably accurate predictions for both wear profile and wear volume/mass whereas the procedure based on the elastic foundation model provides reasonably accurate estimates on the wear volume/mass, is computationally faster but provides progressively poor estimates on the wear profile. Finally an example is

  13. Determination of the stressed state of shells of revolution subjected to the action of local loads

    International Nuclear Information System (INIS)

    The classical statement of the problem of determining the stable state of shells of revolution is based on the assumption that the precritical stressed state is momentless. In certain cases it is not all difficult to determine this state. But under the effect of local loads the problem is no longer trivial. Formulas which express the forces of the momentless stressed state are obtained in the present article. These formulas may be used for the solution of certain stability problems

    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.

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

    International Nuclear Information System (INIS)

    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.

  17. A Hierarchy of Linear Threshold Models for the Spread of Political Revolutions on Social Networks

    CERN Document Server

    Lang, John C

    2015-01-01

    We study a linear threshold agent-based model (ABM) for the spread of political revolutions on social networks using empirical network data. We propose new techniques for building a hierarchy of simplified ordinary differential equation (ODE) based models that aim to capture essential features of the ABM, including effects of the actual networks, and give insight in the parameter regime transitions of the ABM. We relate the ABM and the hierarchy of models to a population-level compartmental ODE model that we proposed previously for the spread of political revolutions [1], which is shown to be mathematically consistent with the proposed ABM and provides a way to analyze the global behaviour of the ABM. This consistency with the linear threshold ABM also provides further justification a posteriori for the compartmental model of [1]. Extending concepts from epidemiological modelling, we define a basic reproduction number $R_0$ for the linear threshold ABM and apply it to predict ABM behaviour on empirical networ...

    Levine, H. S.; Svalbonas, V.

    1974-01-01

    This paper describes the latest addition to the STARS system of computer programs, STARS-2P, for the plastic, large deflection analysis of axisymmetrically loaded shells of revolution. The STARS system uses a numerical integration scheme to solve the governing differential equations. Several unique features for shell of revolution programs that are included in the STARS-2P program are described. These include orthotropic nonlinear kinematic hardening theory, a variety of shell wall cross sections and discrete ring stiffeners, cyclic and nonproportional mechanical and thermal loading capability, the coupled axisymmetric large deflection elasto-plastic torsion problem, an extensive restart option, arbitrary branching capability, and the provision for the inelastic treatment of smeared stiffeners, isogrid, and waffle wall constructions. To affirm the validity of the results, comparisons with available theoretical and experimental data are presented.

  9. Complexity and the Limits of Revolution: What Will Happen to the Arab Spring?

    CERN Document Server

    Gard-Murray, Alexander S

    2012-01-01

    The recent social unrest across the Middle East and North Africa has deposed dictators who had ruled for decades. While the events have been hailed as an "Arab Spring" by those who hope that repressive autocracies will be replaced by democracies, what sort of regimes will eventually emerge from the crisis remains far from certain. Here we provide a complex systems framework, validated by historical precedent, to help answer this question. We describe the dynamics of governmental change as an evolutionary process similar to biological evolution, in which complex organizations gradually arise by replication, variation and competitive selection. Different kinds of governments, however, have differing levels of complexity. Democracies must be more systemically complex than autocracies because of their need to incorporate large numbers of people in decision-making. This difference has important implications for the relative robustness of democratic and autocratic governments after revolutions. Revolutions may disr...

    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.

    International Nuclear Information System (INIS)

    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.

    During the first two months of 2011, the Arab Spring reached Egypt, and toppled president Hosni Mubarak. After the dissolution of the authoritarian regime, sectarian clashes between members of the two largest communities in the country, Muslims and Coptic Christians, exploded. Before the revolution, Egyptian media was used both by the Muslim and the Christian community to incite hatred towards the other, and thus helped prolong the conflict between them.

  3. The revolution of shale oils in the United States. The business model is being tested

    International Nuclear Information System (INIS)

    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

    2012-01-01

    The self-immolation of Mohamed Bouazizi on December 17, 2011 in the small Tunisian city of Sidi Bouzid, set off a sequence of events culminating in the revolutions of the Arab Spring. It is widely believed that the Internet and social media played a critical role in the growth and success of protests that led to the downfall of the regimes in Egypt and Tunisia. However, the precise mechanisms by which these new media affected the course of events remain unclear. We introduce a simple compartmental model for the dynamics of a revolution in a dictatorial regime such as Tunisia or Egypt which takes into account the role of the Internet and social media. An elementary mathematical analysis of the model identifies four main parameter regions: stable police state, meta-stable police state, unstable police state, and failed state. We illustrate how these regions capture, at least qualitatively, a wide range of scenarios observed in the context of revolutionary movements by considering the revolutions in Tunisia and ...

  9. Application of GM crops in Sub-Saharan Africa: lessons learned from Green Revolution.

    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.

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

    International Nuclear Information System (INIS)

    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.

    Nanotechnology as a social concept and investment focal point has drawn much attention. Here we consider the place of nanotechnology in the second great technological revolution of mankind that began some 200 years ago. The so-called nanotechnology revolution represents both a continuation of prior science and technology trends and a re-awakening to the benefits of significant investment in fundamental research. We consider the role the military might play in the development of nanotechnology innovations, nanotechnology's context in the history of technology, and the global competition to lead the next technological revolution.

    A method of the numerical solution of nonlinear unsteady problems of axisymmetric elastoplastic straining of shells of revolution with allowance for torque loading at high strains is proposed. The method is based on the geometrically nonlinear theory of the Timoshenko shells and the plasticity theory with due allowance for combined isotropic and kinematic hardening. The problem is solved with the use of the variational difference method. Results of numerical and experimental investigations of elastoplastic straining of cylindrical shells under proportional and sequential kinematic tensile and torque loading are reported.

    2016-04-01

    Various types of cutters (spherical, toroidal, etc.) are used in surface processing of parts of a transmission mechanism. The cost of a special profile tool is somewhat higher than that of such cutters. But the increase in the cost of the tool is compensated by a significant reduction in the time of processing parts. The present paper deals with a mathematical model of a profile cutter surface (as a surface of revolution) for processing parts of a cylindrical transmission gear with an eccentrically cycloidal gearing (EC-gearing). A computer program for determining radii of the cutter's circular cross sections for a given set of axial displacements was created.

    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.

  20. Creep deformations of shells of revolution under asymmetrical loading

    International Nuclear Information System (INIS)

    In this paper the analytical formulation on the creep of axisymmetric shells undergoing unsymmetrical deformations is developed for two hardening laws: the time hardening law and the strain hardening law. The method is based on the creep power law, and on the assumption of plane stress condition and the Euler-Bernoulli hypothesis used in the ordinary thin shell theory. The basic differential equations derived for incremental values with respect to time are numerically solved by a finite difference method and the solutions at any time are obtained by integration of the incremental values. In conclusion the computer programs are developed which can be used to predict the creep deformations of arbitrary axisymmetrical shells. As a numerical example the creep deformation of cylindrical shell of importance in practical use is treated, and the variations of displacements and internal forces with the lapse of time are discussed.

  2. 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.

  3. Analysis of piping loads on shells of revolution

    International Nuclear Information System (INIS)

    The work of Bijaard as presented by Wichman, et al., Welding Research Council Bulletin 107 (1965), is widely used in industry to evaluate the effects of concentrated loads on cylinders and spheres. But many axially symmetric structures have configuration which preclude the use of this work. In such cases, the procedure given in this paper can greatly reduce the computational effort needed to obtain accurate stresses and deflections due to loads such as occur at piping connections. The paper provides a method of calculating the truncation error due to terminating the Fourier expansion of a loading at a given point. Also for various common loading situations, it provides points where the truncation error is zero. (Auth.)

  7. Transient dynamic and inelastic analysis of shells of revolution - a survey of programs

    International Nuclear Information System (INIS)

    Advances in the limits of structural use in the aerospace and nuclear power industries over the past years have increased the requirements upon the applicable analytical computer programs to include accurate capabilities for inelastic and transient dynamic analyses. In many minds, however, this advanced capability is unequivocally linked with the large scale, general purpose, finite element programs. This idea is also combined with the view that such analyses are therefore prohibitively expensive and should be relegated to the 'last resort' classification. While this, in the general sense, may indeed be the case, if the user needs only to analyze structures falling into limited categories, however, he may find that a variety of smaller special purpose programs are available which do not put an undue strain upon his resources. One such structural category is shells of revolution. This survey of programs concentrates upon the analytical tools which have been developed predominantly for shells of revolution. The survey is subdivided into three parts: (a) consideration of programs for transient dynamic analysis; (b) consideration of programs for inelastic analysis and finally; (c) consideration of programs capable of dynamic plasticity analysis. In each part, programs based upon finite difference, finite element, and numerical integration methods are considered. The programs are compared on the basis of analytical capabilities, and ease of idealization and use. In each part of the survey sample problems are utilized to exemplify the state-of-the-art.

  13. Choices in the next energy and social revolution. [For development of solar as against nuclear fusion

    Energy Technology Data Exchange (ETDEWEB)

    Ryan, C.J.

    1977-07-07

    The purpose of this paper is to provide a context for choosing the energy system that will replace fossil fuels. As fossil fuels, the energy source of industrialization, are depleted, the world enters into the third most important energy and social revolution in the development of civilization. Natural and social systems operate under the same principles of energy management. Growth, stability, or decline is determined by the interdependent relationship between energy and structure (Energy in Natural and Social Systems). The evolution of civilization over more than a million years can be seen as a successful quest to control greater amounts of energy through social organization in three different energy and social systems: hunting and gathering, agriculture, and fossil fuels (Two Energy and Social Revolutions). Many nations based on different energy and social structures have flourished and disappeared throughout history. The cases of Egypt, Rome, and Britain are used to illustrate the dynamic forces that affect the rise and fall of empires, dependence on foreign resources, and the changing purposes of social organization (The Influence of Energy on Nations). The energy perspective of the paper suggests the relationship between continuous growth and social discontinuity in U.S. history (Continuous Growth and Social Discontinuity in the U.S.). The physical and social consequences of future energy alternatives are discussed in terms of an Orwellian, Jeffersonian, and Malthusian type future (The Third Revolution: Orwell, Jefferson, or Malthus). The paper concludes with an endorsement of solar energy as the alternative most likely to afford a stable future in a humanly organized environment.

    The American Thoracic Society (ATS), the preeminent professional organization in the field of respiratory, critical care, and sleep medicine, is now 107 years old. For the most part, the Society's administrative and medical-scientific interests evolved in an orderly fashion, but two "revolutions" took place that should be remembered. What ultimately metamorphosed into the ATS in 1960 began in 1905 as the 34-member American Sanatorium Association, which in 1915 became the medical section of the National Association for the Study and Prevention of Tuberculosis (NASPT). In 1918, the NASPT became the National Tuberculosis Association and in 1939, the ASA became the American Trudeau Society, cosmetic revisions having no effect on either the medical section-parent relationship or the one-disease orientation of both organizations. After World War II, the narrow focus of the ATS on tuberculosis was progressively enlarged through coalescence of several factors that transformed the practice of pulmonary medicine: the growth of intensive care units and pulmonary function laboratories and the advent of fiberoptic bronchoscopy; the rise of asthma, chronic obstructive pulmonary disease, and lung cancer coincident with the withering of tuberculosis; and the arrival of pulmonary physician-scientists who sought enrichment through a professional society. The newcomers found a home in the ATS, but it was slow to fulfill their needs for scientific communication and administrative responsibility. The first revolution, the formation of Scientific Assemblies, got the job done quickly and well, as described in Part 1 of this perspective. The second revolution, separation from the American Lung Association, is described in Part 2. PMID:22822021

    The effects of divorce on individuals and on society as a whole has been widely debated in public discussion of American life. The dialogue was sparked by the dramatic rise in the number of U.S. divorces which began in the 1960s: Figure 1 illustrates that the divorce rate doubled from 10.6 to 20.3 divorces per 1,000 married women between 1965 and 1975, and continued to rise until 1981. Scholars have also debated the implications of the 'Divorce Revolution' of this time period: the liberalizat...

  14. The romantic revolution of the Western Middle-Class family

    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.

If vascular surgery is to emerge as a high quality service then vascular emergencies--a substantial component of the workload--should be dealt with by surgeons with adequate training, and all patients should have equal access to the service. A specialist vascular surgical unit would have to be large enough to make efficient use of other services that it ne...

  3. Pros and cons of the revolution in radiation protection

    International Nuclear Information System (INIS)

    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

    Lung cancer prevention and early detection, which have fallen on hard times for more than the past 20 years, seem to have turned a corner toward better times ahead. Exciting new results of randomized controlled trials that targeted the arachidonic acid pathway, including a celecoxib trial reported by Mao and colleagues in this issue of the journal (beginning on page 984) and a trial of the prostacyclin analog iloprost, complement recently reported 20%-30% lung cancer mortality reductions, either with aspirin in targeting the arachidonic acid pathway or with computed tomography screening. The new results show encouraging activity personalized to former smokers and/or people expressing predictive biomarkers. These trials and technological advances in molecular profiling and imaging herald substantial clinical advances on the horizon of this field. PMID:21733817

  15. Biological Computation as the Revolution of Complex Engineered Systems

    CERN Document Server

    Gómez-Cruz, Nelson Alfonso

    2011-01-01

    Provided that there is no theoretical frame for complex engineered systems (CES) as yet, this paper claims that bio-inspired engineering can help provide such a frame. Within CES bio-inspired systems play a key role. The disclosure from bio-inspired systems and biological computation has not been sufficiently worked out, however. Biological computation is to be taken as the processing of information by living systems that is carried out in polynomial time, i.e., efficiently; such processing however is grasped by current science and research as an intractable problem (for instance, the protein folding problem). A remark is needed here: P versus NP problems should be well defined and delimited but biological computation problems are not. The shift from conventional engineering to bio-inspired engineering needs bring the subject (or problem) of computability to a new level. Within the frame of computation, so far, the prevailing paradigm is still the Turing-Church thesis. In other words, conventional engineering...

    2010-01-01

    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.

    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: Black-Right-Pointing-Pointer Evidence of the South Korea contamination with released radiocesium from Fukushima.

  20. Finite element analysis program for shells of revolution: ISTRAN/SR, 4

    International Nuclear Information System (INIS)

    The computational capabilities available in the current version of ISTRAN/SR for stress analysis of shells of revolution have been described in the 1st, 2nd and 3rd reports. This report describes the linear elastic dynamic analysis of shells of revolution under axisymmetric and asymmetric loadings. The shell, idealized as a curved element and cubic function for all displacements, is used. A method for solution of the equations of motion is described with special emphasis on the computational aspect of the solution. Three solution methods, which can be employed for the linear dynamic analysis, are possible - direct integration method, mode superposition method, and spectrum analysis method. Each method involves a numerical method which must be formulated in effective form for computer implementation - solution of linear equations, evaluation of eigenvalues and eigenvectors, and step-by-step numerical integration. In this program, the skyline method is employed for the solution of linear equations, and the subspace method and the determinant search method are employed for eigenproblem. The Newmark-Wilson method is employed for the step-by-step integration. The comparison of the solution of ISTRAN/SR and other numerical solution shows good agreement. (author)

  2. Regulation of optimal proportion fuel-air by the change of number of fan revolutions

    International Nuclear Information System (INIS)

    The conventional manner of combustion regulation with mechanical adjustment of the proportion fuel-air provides qualitative combustion only at the moment of adjustment. During the exploitation a number of factors can cause the disturbances of the adjusted proportion of fuel and gas, and in most cases they are: temperature, pressure and combustion air humidity, pressure and thermal power of fuel, clearances in lever mechanism and wearing of the burner parts. Regulation of the combustion quality by change of quantity of fuel and air pressure engages the fan almost continuously on nominal power and afterwards by throttling the air stream energy is wasted. Only by the change of the number of fresh air fan revolutions, we can provide the correct proportion of fuel and air without losing the energy for air throttling, as the frequent regulator optimizes electric power consumption by the vector regulation (voltage and frequency). Controlling the combustion process on the basis of measuring the oxygen content in the combustion products by application the frequent regulator for the change of number of fan revolutions is far better way of regulation of the proportion fuel and air for combustion. By simple connecting the analyzer for oxygen content in combustion products and frequent regulator to regulation circle we compensate all disturbances appearing during the burner exploitation. The solution can be applied to each burner with continuous regulation regardless to the producer, kind of fuel and automatics. Besides the savings in electric (50%) and thermal energy (1%) and elimination of carbon monoxide emission in the atmosphere, this solution provides the safe protection of the motor against electric disturbances. The payback of this solution is on the level of one-year exploitation (5700 h). (Author)

    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.

  6. Optimization of multi-revolution low-thrust transfer based on modified direct method

    2008-01-01

    A modified direct optimization method is proposed to solve the optimal muhi-revolution transfer with low-thrust between Earth-orbits. First, through parametefizing the control steering angles by costate variables, the search space of free parameters has been decreased. Then, in order to obtain the global optimal solution ef-fectively and robustly, the simulated annealing and penalty function strategies were used to handle the con-straints, and a GA/SQP hybrid optimization algorithm was utilized to solve the parameter optimization problem, in which, a feasible suboptimal solution obtained by GA was submitted as an initial parameter set to SQP for re-finement. Comparing to the classical direct method, this novel method has fewer free parameters, needs not ini-tial guesses, and has higher computation precision. An optimal-fuel transfer problem from LEO to GEO was taken as an example to validate the proposed approach. The results of simulation indicate that our approach is a-vailable to solve the problem of optimal multi-revolution transfer between Earth-orbits.

  10. 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.

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

    Directory of Open Access Journals (Sweden)

    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.

  12. Simplified vibration analysis method of shells of revolution using beam model

    International Nuclear Information System (INIS)

    A simplified vibration analysis method for the shells of revolution using the beam model is now under consideration. In the beam model, the relations between the shear forces and horizontal deformations are used for the calculations of the shear area and the relations between the overturning moments and rotation angles are for those of the inertia moment. The calculations of the vibration characteristics of the cylindrical shell, spherical shell and the cylindrical shell with the spherical cap were conducted to verify the accuracy of the beam model. The natural frequencies and the vibration modes of the proposed method are in good agreement with that of the FEM analysis using the axisymmetrical shell model. The proposed method is easily applicable to the vibration analysis of actual shell structures. (author)

    2013-05-01

    Full Text Available Color revolution is one of the new ways of changing a regime at the beginning of the twenty-first century, which has usually been carried out on corrupt, political systems remaining from the Cold War era in Eastern European countries and countries that have become independent from the former Soviet Union and through such revolution a new peaceful form of political power transition emerged. An exploration of the circumstances of Ukraine’s Orange Revolution suggests foreigners’ support and leading. Ukraine’s presidential elections of 2004 and the competition between Viktor Yushchenko and Victor Yanukovich and the presence of international observers in the process of elections and the controversy of electoral fraud and the West’s support of Yushchenko were all directed toward the formation of a color revolution in Ukraine. Poor economic conditions and official corruption, religious, linguistic, class and racial gaps in Ukraine led the way for foreigners to use them in creating electoral situations and prepare the fall of the government. The main purpose question in this article is the Orange Revolution and its causes.

  16. Strategy as revolution.

    Hamel, G

    1996-01-01

    How often does the strategic-planning process start with senior executives asking what the rest of the organization can teach them about the future? Not often enough, argues Gary Hamel. In many companies, strategy making is an elitist procedure and ¿strategy¿ consists of nothing more than following the industry's rules. But more and more companies, intent on overturning the industrial order, are rewriting those rules. What can industry incumbents do? Either surrender the future to revolutionary challengers or revolutionize the way their companies create strategy. What is needed is not a tweak to the traditional strategic-planning process, Hamel says, but a new philosophical foundation: strategy is revolution. Hamel offers ten principles to help a company think about the challenge of creating truly revolutionary strategies. Perhaps the most fundamental principle is that so-called strategic planning doesn't produce true strategic innovation. The traditional planning process is little more than a rote procedure in which deeply held assumptions and industry conventions are reinforced rather than challenged. Such a process harnesses only a tiny proportion of an organization's creative potential. If there is to be any hope of industry revolution, senior managers must give up their monopoly on the creation of strategy. They must embrace a truly democratic process that can give voice to the revolutionaries that exist in every company. If senior managers are unwilling to do this, employees must become strategy activists. The opportunities for industry revolution are mostly unexplored. One thing is certain: if you don't let the revolutionaries challenge you from within, they will eventually challenge you from without--in the marketplace. PMID:10158475

    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. PMID:20430069

  18. Environmental justice: a form of passive revolution and civil society against capitalist system hegemony

    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

    International Nuclear Information System (INIS)

    The first energy revolution was the changeover from wood to coal, the second one from coal to oil and now we are facing the passage from oil to CO2-no-emitting energy sources. The global energy equation of the world implies a permanent growth of the energy demand so the combining of energy conservation measures and the development of renewable energies go in the right direction but it will not be enough. We have to develop energy sources that do not worsen the climatic change and stay competitive. Nuclear power is one of them, it has the advantage of existing and relying on a broad feedback experience. Areva has made large investment to face a renaissance of nuclear power worldwide. Nuclear power appears to have significant strategical, economical and environmental assets and recent opinion polls show a real general trend in favor of this energy. (A.C.)

    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." PMID:26109413

    2008-06-01

    Full Text Available This article maps the legal developments that led to the adoption of the Civil Union Act, which extended full marriage rights to same-sex couples in South Africa. It points out that this extension of marriage to same-sex couples would not have been possible if it was not for the groundbreaking decisions on sexual orientation discrimination handed down by the South African Constitutional Court over the past ten years. It al so describes the complex legal regime now in place which allows different sex couples to enter into marriage in terms of a traditional Marriage Act or the new Civil Union Act but restricts same-sex couples to entering into marriage in terms of the latter Act. The article concludes that while this extension of marriage rights can be viewed as a legal revolution, some problems remain with the legal regulation of same-sex relationships in South Africa.

    It is an oft-heard complaint that the UK generates some of the best science in the world, but does not reap the full reward. Hard data to verify this are difficult to come by, but at a recent talk in Oxford1, Lord Robert May, president of the Royal Society and former chief scientific advisor to the UK government, tried to quantify the issue. The number of scientific papers published annually is more or less equally divided between the US, Europe, and the rest of the world2. In the league table of publications per capita3, Table 1, European countries do extremely well, pushing the US into 11th place. May also pointed out that the US government spends 0.82% of its gross domestic product (GDP on research, while the EU spends 0.76%. Putting this in context, Japan allocates just 0.64% of GDP and the only countries that budget a higher proportion of GDP than the US are France and Finland4. The UK budgets just under 0.70% of GDP but, taking the somewhat ruthless gauge of cost per paper, comes out top. While these are, perhaps, crude measures, the figures confirm the view that scientific research in Europe is extremely competitive.

    Global population will increase by almost 1 billion people in the 1990s, the largest 10-year increase ever recorded. In 1994 alone, population will surpass 5.7 billion. The prospect of double-digit billions of people is worrisome, especially since these numbers may affect global warming, supplies of fresh water, destruction of rain forests, industrial pollution, and sustainable development. Yet, many indicators of quality of life show that people enjoy a better quality of life today than they did 100 years ago. Between India's independence and now, life expectancy increased by 20 years, infant mortality decreased 2-fold, literacy increased, and the food supply stabilized. Even though India's population has almost tripled since 1947, its economy increased rapidly and is 1 of the world's top 10 economies. University enrollment stands at 4.5 million. Agricultural production has exceeded demand. India represents the potential for human achievement through technological advancement and social organization. If the world's first national family planning program had been more successful when it began in 1952 in an India of 350 million people, India's population would be around 500 million instead of the expected 1 billion in 2000. All countries need to achieve a sustainable balance between human numbers and needs and natural resources. Family planning is an essential, cost-effective part of any development strategy. Family planning use has reduced fertility from 6 to 3.6 in developing countries. In 1965, only 8% used contraception, while more than 50% use it now. The most remarkable family planning/fertility reduction successes are Bangladesh, Brazil, Colombia, Indonesia, Mexico, and Thailand. Sufficient investment in family planning is needed if significant declines in fertility are to occur. More than 90% of the developing world's people are in countries with official family planning programs. Cost-effective assistance by donors and developing countries implementing

    Harken, A H

    1976-11-01

    In this bicentennial year, it seems appropriate that each discipline examine its heritage. Two centuries ago, Joseph Priestley isolated "dephlogisticated air." International diplomacy surrounding the American and early French Revolutions provided an opportunity for Benjamin Franklin and Antoine Lavoisier to witness Priestley's work. The combined efforts of these analytical minds converted an illogical phlogiston myth into a practical and therapeutic principle. Lavoisier subsequently coined the word "oxy-gène." In the ensuing centuries, this substance has gained a central role in rational surgical therapy. The interaction between these scientists, their ultimate fate and their relationship to their communities appear to provide lessons relevant to present day biomedical research funding and the peer review process. The surgical community can be justifiably proud of its past. By reflecting on these events, we may perhaps concentrate the benefits without condemning ourselves to the repetition of previous error.

    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

    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.

    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.

    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.

  20. Toward a microbial Neolithic revolution in buildings.

    Thaler, David S

    2016-01-01

    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

    Science.gov (United States)

    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.

    Full Text Available The proper estimation of computer technologies is very important when computers are to be implemented in the educational process. Otherwise, if not implemented properly, the quality of students' education may be seriously imperiled. This is crucial when Descriptive geometry (DG is the matter; the discipline that develops and improves the students' spatial visualization ability (SVA. Unfortunately, nowadays, there is a tendency that some educators, mostly non- geometricians, being destitute of profound knowledge of DG, and not fully understanding the fundamental importance of DG, find themselves involved in computerization of DG, using various CAD programs and thus, force students to (computer aided − CA draw already well known standardized objects and consequently train their capabilities typical for draughtsman. In this paper we, propose how and to which extent the computerization of DG should be carried out. The previous has been governed by the criteria of facilitating students' comprehension of spatial relationships, orientation and visualization. We have developed the procedure for the representation of surfaces of revolution (SOR and their shades and shadows on planes. What is to be emphasized on the matter is that each CA approach to DG teaching should follow the traditional DG reasoning and the step-by-step acquisition of fine solution, offering students the possibility of gradual process of visualization.

  10. Extraction Of Surface Parameters From Depth Maps Viewing Planes And Quadrics Of Revolution

    Science.gov (United States)

    Sabbah, Daniel; Bolle, Ruud M.

    1987-03-01

    This paper presents a first step in the definition and construction of a vision system to recognize three-dimensional objects whose surface are composed of planar patches and patches of quadrics of revolution. A large portion of man-made objects can be either modeled exactly, or at least well approximated by a number of patches of such surfaces. The problems addressed in this paper are three-dimensional surface recognition and parameter extraction from noisy depth maps viewing one surface. The basis for the surface recognition and parameter estimation is the curvature information that can be extracted from polynomial approximations to the range data. The curvature properties are derived directly from the Weingarten map, a well-known concept from classical differential geometry. The actual process of recognition and parameter extraction is framed as a set of stacked parameter space transforms that compute measures of confidence in an iterative refinement, or multi-level relaxation, scheme. This scheme resulted from experiments with connectionist visual recognition systems. The measure of confidence associates a measure with a hypothesis that a parameterization (corresponding to a surface) actually exists in the scene.

  11. 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

  14. Ruin and Revolution in ``Hamlet."

    1999-05-01

    In the cosmic allegorical interpretation of Shakespeare's "Hamlet" (BAAS 28, 859 & 1305, 1996; Mercury 26:1, 20, 1997; RPS 18:3, 6, 1997; Giornale di Astronomia 24:3, 27, 1998), the usurper King Claudius, namesake of Ptolemy, personifies geocentricity. Textual support for this reading is found in 1.2 where Hamlet is associated with the Sun, as befits a rightful heir, while Claudius is associated with the Earth. In 3.3 Claudius fears Hamlet's antics. Rosencrantz states that the lives of many depend on the well-being of the King. He warns that if the King were to be imperiled, his subjects, those "ten thousand lesser things", would fall in a "boisterous ruin" along with "each small annexment" and "petty consequence." These 10,000 lesser lights are the naked eye stars (mv ~ 6.5) which would collapse with the demise of the pre-Diggesian firmament, along with ancient planets and their geometrical contrivances. In 5.1 Shakespeare puns on "De revolutionibus" when he refers to "fine revolution." The double meaning of "revolution" (alteration, orbital motion) was in use long before 1600. Since "revolution" is used in the context of digging, it may refer as much to the Diggesian as the Copernican Revolution. Shakespeare's prescience is revealed by his anticipation of change, as encapsulated geocentricity is transformed to stellar boundlessness, while his presence is suggested by fatherly concerns and ghost-like direction.

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

    Science.gov (United States)

    Kulkarni, Makarand; Noor, Ahmed K.

    1995-04-01

    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.

    Full Text Available Egypt, the most populated country in the Arab world, erupted in mass protests in January 2011 against the oppressive rule of President Hosni Mubarak. Protesters all over Egypt in general and in Tahrir Square in Cairo wanted Mubarak to leave. Protesters used different dialects, languages, and modes to get their message across. After 18 days of angry protests and after losing the support of the military and the US, Mubarak finally understood the message and resigned on Feb. 11, ending almost 30 years of dictatorial rule. This article builds on studies in Critical Discourse Analysis (CDA and its implementation of interdisciplinarity to investigate the slogans―fixed expressions, usually chosen carefully by organizers and activists, which are often chanted by political groups and protestors at demonstrations that were used during the Egyptian revolution in late January and February 2011. Moreover, the article shows how CDA―through embracing text as a dialogue and site for interaction, social goods and social languages, interpersonal relations and discourse, multimodality, and intertextuality can help to produce theoretically sound interpretation that is appropriate for the analysis of how Egyptians used the power of language through these slogans to empower themselves, challenge their government, and overthrow the former president Hosni Mubarak.

    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.

  20. Scrutinizing the epigenetics revolution.

    Science.gov (United States)

    Meloni, Maurizio; Testa, Giuseppe

    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.

  4. The "Revolution in chemistry and physics." Overthrow of a reigning paradigm or competition between contemporary research programs?

    Science.gov (United States)

    Holmes, F L

    2000-12-01

    Recent revisionist interpretations of the chemical revolution have left intact the core of the traditional view that its central feature was the overthow of the phlogiston theory by the oxygen theory of combustion of Antoine Lavoisier. The central confrontation has been seen as that between the adherents of the chemical system that Lavoisier built around his theory and the form of the phlogiston theory defended by Joseph Priestley. This essay contends that Priestley's use of phlogiston was so loosely connected with the older phlogiston theories descended from that of Georg Ernst Stahl that the events at the heart of the chemical revolution should be viewed more as a competition between two rival new research programs than as the replacement of a reigning paradigm.

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.

  9. Finite element analysis program for shells of revolution: ISTRAN/SR, 5

    International Nuclear Information System (INIS)

    In recent years, it has been recognized that the capability of performing effective inelastic analysis is a very important asset in designing nuclear power plants and chemical plants with the trent toward high temperature conditions. The safety of the structure may be increased if an accurate inelastic analysis can be performed. Generally, the inelastic analysis is calculated by using incremental solution of the equations of equilibrium. To improve the accuracy of solution and to prevent the development of instabilities, it may be necessary to use equilibrium iteration in preselected load steps. We developed the stable and efficient solution procedure of inelastic analysis and used this technique in computer program ISTRAN/SR (IHI STRucture ANalysis/Shells of Revolution). In this paper, we present the outline of the theory and numerical technique used in ISTRAN/SR and the results of analysis to give some indications of the capabilities of this program. The program can be employed effectively for the number of problems including the thermo-elastic-plastic-creep analysis. (author)

    Since Edward Leamer's memorable 1983 paper, "Let's Take the Con out of Econometrics," empirical microeconomics has experienced a credibility revolution. While Leamer's suggested remedy, sensitivity analysis, has played a role in this, we argue that the primary engine driving improvement has been a focus on the quality of empirical research designs. The advantages of a good research design are perhaps most easily apparent in research using random assignment. We begin with an overview of Leamer...

    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.

  12. The edge of expertise: Representing barefoot doctors in Cultural Revolution China.

    Li, Lan Angela

    2015-01-01

    ‘Barefoot doctors’ were designed as an innovative task force during the Cultural Revolution (1966-1976) to provide health care to rural villages in China. Without formal training that would identify the group professionally, barefoot doctors were at once amateur medical practitioners and expert revolutionary actors in Communist Party propaganda. At stake in legitimating revolutionary medicine was allowing revolutionary spirit to supplement for minimal medical training. As a result, the symbolic power of representing barefoot doctors rested in showcasing their devotion to enhancing access to health care in rural China. These representations followed an intensifying militarization of civilians, embracing the barefoot doctor’s ability to survive any obstacle while also celebrating those who died in the process. This paper examines three public portrayals of barefoot doctors, arguing that conflicting idealizations of rural epistemology combined the opposing elements of self-cultivation and self-annihilation to unite the identity of an emerging group of amateur doctors and illustrate acceptable forms of medical and revolutionary expertise.

    The small hydroelectric power station of Rupboden in the Oberfranken district was reactivated after having been decommissioned for 30 years. This new low pressure plant consists of an open-flume turbine with an adjustable diffusor and a firm rotor disk (propeller) with a vertical rod. A large range of operation at a constant height of fall is ensured by a variable revolution number. The profiles of the adjustable diffusor and rotor disk and the design of the draft tube were optimized using numerical flow calculation. First operating experience is very positive. The turbine runs extremely smoothly over the entire range. (orig.) [Deutsch] Das Kleinwasserkraftwerk Rupboden in Oberfanken wurde nach 30 Jahren Stillstand reaktiviert.

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

    Science.gov (United States)

    Scanlon, Thomas F

    2005-01-01

    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. PMID:16338890

  18. Addendum to the Agency's Annual Report to the Economic and Social Council of the United Nations for 1970-71. Nuclear Technics and the Green Revolution

    International Nuclear Information System (INIS)

    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.

  20. From Revolution to Evolution: 21 Years of the IRIS Data Management Facility

    Benson, R. B.; Ahern, T. K.; Trabant, C. M.; Casey, R.

    2009-12-01

    A revolution is defined as a "drastic and far-reaching change in the way of thinking and behaving", and this describes the effect that the IRIS Data Management System (DMS) has had in the framework of seismological research. The IRIS Data Management Center (DMC) prototype began operation at theUniversity of Texas at Austin in 1988 and has evolved to to a fully functioning facility at the University of Washington in Seattle. The focus of this submission is to share an historical timeline of events related to the DMC, a bit of scrap-booking perhaps, centered around the business of waveform data management conducted by IRIS and it's partners. We hope to illustrate how the successful philosophy of sharing unrestricted data, openly collaborating with a global network of networks, and partnering with computer and software industry vendors that have supported our community's academic research, has enabled generations of seismologists to both curate and continually "mine" the ever-growing 45 years of digital data currently stored in the perpetual archive located in Seattle, WA. At the time that the Loma Prieta Earthquake shook and burned San Francisco on October 17, 1989, there were only 3 stations which had dial-up modems enabling what then was considered "fast access" to waveform data delivery from them back to the DMC. This was considered the first test of the DMC, since waveform data were collected and distributed within days of this event. But this was only a foretelling of things to come, since the rates of archiving and distribution have continually grown to a current 1900+ stations and a 17,000+ channel count of real-time data streaming in and out of the DMC daily, totaling 50 Terabytes of data shipped in 2009 alone. We will attempt to summarize the important technological challenges, solutions, and growth of the DMC with the goal of illustrating that "if you build it, they will come", and how this could be useful to other organizations.

    A major technological revolution is on the horizon that promises cures for inherited diseases such as cystic fibrosis, sickle cell anemia, muscular dystrophy, hemophilia, leukocyte-adhesion deficiency, and Gaucher's disease. This revolutionary technology also promises effective treatments for acquired diseases such as cancer and AIDS. The technique is gene therapy and it has already been used in humans. Some applications raise ethical considerations that not only affect the individual who is treated but have implications for future generations as well. PMID:10134065

  2. The safeguards revolution: Contributions and perspectives of the Standing Advisory Group on Safeguards Implementation

    International Nuclear Information System (INIS)

    Full text: It is no exaggeration to describe the ongoing changes to the IAEA safeguards system as revolutionary. In the past decade safeguards have moved from a relatively routine system, operating in a seemingly benign environment, to a system undergoing radical change, having to reinvent itself to respond to major challenges. Yet the process of revolution has a long way to go. The conceptual framework for the new safeguards has been developed, but this framework has to be consolidated through new implementation practices. In this sense the revolution needs to be ongoing. There is much more to be done if the safeguards system is to be successful in meeting the challenges. When the traditional safeguards system was introduced, in the early 1970s following the conclusion of the NPT, the objectives of the safeguards system were seen as being very different to today. At that time it was thought that proliferation would require diversion of safeguarded nuclear material, and misuse of safeguarded nuclear facilities. It was considered beyond the capability of most States to establish a wholly clandestine nuclear fuel cycle, independent of safeguarded nuclear material and facilities. So, it was thought, countering proliferation was a matter of applying suitably rigorous safeguards procedures to declared material and facilities. During the 1970s and 1980s the traditional safeguards system developed in conditions of apparent stability, where the main challenge was seen as resource allocation, how to manage a steadily growing workload with a relatively static budget. During this period the traditional safeguards system developed with an emphasis on nuclear materials accountancy, and on verifying the correctness of declared nuclear material inventories. The organisational culture developed around the use of quantitative and relatively mechanistic procedures. This culture was reinforced through a particular policy perspective, specifically, that avoiding discrimination

    As part of the Earth and Space Science Revolution, there is increased encouragement for the scientific community to collaborate with the educational community to enhance understanding of the Earth's systems and processes. At the national level, there is a concerted effort to marshal the scientific expertise of national laboratories through partnerships with educators. Drawing on the well-established leadership role of the University Corporation for Atmospheric Research (UCAR) in atmospheric and related scientific research, UCAR's Office of Education and Outreach (EO) is taking an active role in education efforts in Earth science. These efforts focus on a variety of venues -- informal and public education as well as K-12, undergraduate, graduate, and post-doctoral education. EO is the point of contact and dissemination for education and outreach at UCAR, the National Center for Atmospheric Research (NCAR), and the UCAR Office of Programs (UOP). EO collaborates with NCAR scientists through the creation of K-12 educational resources and technologies, professional development workshops, special events, public tours, and exhibits. Recognizing that national laboratories such as NCAR are unique and can make significant contributions to science education reform and the implementation of national standards in science, mathematics, and technology, UCAR is actively supporting programs that translate scientific content for k-12 classrooms and the general public while also providing research opportunities for diverse learners. Although there is a long history of scientists and national laboratories working with educators, there is a critical need for documentation and understanding of the best practices associated with such collaborations. UCAR is building a framework to gather information from all of its education programs that will inform program organizers and be of use to others interested in implementing similar programs.

    The Anthropocene colloquially refers to a global regime of human-caused environmental modification of earth systems associated with profound changes in patterns of human mobility, as well as settlement and resource use compared with prior eras. Some have argued that the processes generating the Anthropocene are mainly associated with population growth and technological innovation, and thus began only in the late Holocene under conditions of dense sedentism and industrial agriculture.(1) However, it now seems clear that the roots of the Anthropocene lie in complex processes of intensification that significantly predate transitions to agriculture.(2,3) What intensification is remains less clear. For some it is increasing economic productivity that increases carrying capacity, the drivers of which may be too diverse and too local to generalize.(4,5) For others using Boserup's ideas about agrarian intensification, increasing density in hunter-gatherer populations can produce declines in subsistence efficiency that increase incentives for investing labor to boost yield per unit area, which then elevates Malthusian limits on carrying capacity.(6-8) As Morgan(9) demonstrates in a comprehensive review, the legacy of such Boserupian intensification is alive, well, and controversial in hunter-gatherer archeology. This is a result of its potential for illuminating processes involved in transformations of forager socio-political and economic systems, including those dominated by harvesting more immediate-return resources and high residential mobility as well as those characterized by more delayed-return material economies with reduced residential mobility, a broader spectrum of resources, degrees of storage, and greater social stratification. Here we detail hypotheses about the processes involved in such transitions and explore the way that anthropogenic disturbance of ecosystems, especially the use of landscape fire, could be fundamentally entangled with many broad

  6. 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.

  7. The Disquieting Revolution: A Genealogy of Reason and Racism in the Québec Press

    Directory of Open Access Journals (Sweden)

    Alan Wong

    2011-01-01

    Full Text Available Within the past decade, a series of contentious events concerning the accommodation of different cultural and religious traditions and practices in Quebec has incited much debate in this region. Labelled the “reasonable accommodation” issue by the local press, this controversy, which has its roots in neo-nationalist sentiments born of the Quiet Revolution, has incited responses ranging from denunciations of racist discrimination to calls for more stringent measures to ensure the assimilation of non-Westerners into Québécois culture. As Monika Kin Gagnon points out, this concept has moved beyond its legal origins to become a “social discourse” in the culture at-large, in that many in Quebec are vocally expressing their anxieties over the idea that the rights of newcomers has reached a tipping point, whereby the limits of reason are now over-stretched, weakening the dominant population’s values and identity. Much of this fear was stoked by certain stakeholders in the 2007 Quebec election, namely politicians and media outlets, when reasonable accommodation was highlighted as a major issue. This paper provides an analysis of that election and the campaigns leading into it, revealing how the press and the leaders of the three major political parties were complicit in transforming some negligible and private incidents into a greater menace endangering the very existence of Quebec society. By tracing the genealogy of “the reasonable Québécois”, I will demonstrate how reason and racism became intertwined during the course of this debate over rights, identity, and citizenship in Quebec.

  8. Revolutions in astronomy, physics and cosmology

    International Nuclear Information System (INIS)

    As consecutive turning-points in the development of natural science four global natural science revolutions (Aristotelian, Newton, Einstein and post-Einstein) are marked out and briefly outlined. Each of them simultaneously occurred in astronomy, physics and cosmology and was accompanied by radical changes of cosmological representations. These changes had quite a regular consecutive character and represented necessary steps in turn along the natural way of further elimination of ego centrism from cosmology. The first (Aristotelian) revolution turnes out a peculiar prototype of all three subsequent revolutions in astronomy, physics and cosmology. The special more detailed analysis of this revolution in this monograph allows one to tie together antique and modern phases of the science development including corresponding representations on fundamental structural elements of the matter. Besides the review of literature data the monograph comprises a series of author's scientific results

  10. CRISES AND REVOLUTION

    Directory of Open Access Journals (Sweden)

    Adrián Sotelo Valencia

    2010-01-01

    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

    Full Text Available Global climate change mitigation and CO2 emission reduction have promoted the revolutionary transformation in energy system. The core content of energy system revolutionary transformation is to replace the high-carbon energy system dominated by fossil energy with low-carbon energy system dominated by new and renewable energy and finally realize the near-zero emission of CO2. The new energy system transformation has also led to a reform in global economic and social development patterns. Developing low-carbon economy becomes the fundamental strategy of sustainable development under climate risk management and the only solution to getting on the road from industrial civilization to ecological civilization. China intends to achieve the peaking of CO2 emissions around 2030 and increase the share of non-fossil fuels in primary energy consumption to around 20% by 2030. Guided by the targets, China directs its economy development to a low-carbon pattern. Therefore, new and renewable power capacity need to reach 1300 GW, and the electricity generated should be 4 times of that in 2013 with a continuous increase rate of 6%–8% around 2030. The pace of energy substitution need to be accelerated and efficient, safe, clean, and low-carbon energy supply and consumption systems should be established besides strengthened energy conservation and improved energy efficient. Therefore, reform need be deepened, favorable policy system and market mechanism for energy revolution and low-carbon development need be established, energy pricing mechanism should be reformed, and national carbon market should be formed to provide a favorable policy and market environment for low-carbon technology innovation and industry development.

    In the 19th century, the United Kingdom began a period of economic transformation known as the Industrial Revolution. It’s commonly believed that this era opened as new inventions improved the technologies used to produce goods and provide services. However, we now know that such improvements affected only a relatively small part of the economy. Nonetheless, output rose during the first stage of the Industrial Revolution because of capital accumulation. One explanation for this increase in ca...

    This paper constructs a two-sector unified growth model that explains the timing and the inevitability of an industrial revolution through entrepreneurs' role for the accumulation of useful knowledge. While learning-by-doing in agriculture eventually allows the preindustrial economy to leave its Malthusian trap, an industrial revolution is delayed as entrepreneurs of the manufacturing sector do not attempt invention if not much is known about natural phenomena. On the other hand, these entrep...

    2014-01-01

    Wearable technology has become an important trend in consumer electronics in the past year. The miniaturization and mass production of myriad sensors have made possible the integration of sensors and output devices in wearable platforms. Despite the consumer focus of the wearable revolution some surgical applications are being developed. These fall into augmentative, assistive, and assessment functions and primarily layer onto current surgical workflows. Some challenges to the adoption of wearable technologies are discussed and a conceptual framework for understanding the potential of wearable technology to revolutionize surgical practice are presented.

    1975-01-01

    The theoretical analysis background for the STARS-2P nonlinear inelastic program is discussed. The theory involved is amenable for the analysis of large deflection inelastic behavior in axisymmetric shells of revolution subjected to axisymmetric loadings. The analysis is capable of considering such effects as those involved in nonproportional and cyclic loading conditions. The following are also discussed: orthotropic nonlinear kinematic hardening theory; shell wall cross sections and discrete ring stiffeners; the coupled axisymmetric large deflection elasto-plastic torsion problem; and the provision for the inelastic treatment of smeared stiffeners, isogrid, and waffle wall constructions.

    第一次绿色革命的潜力已经被充分利用,第二次绿色革命正在兴起.全世界的科学家都在探讨新绿色革命的靶标,包括改善核酮糖-1,5-二磷酸(RuBP)羧化酶/加氧酶(Rubisco)、降低光呼吸和呼吸作用损失、提高RuBP再生能力、改造C3植物成为C4植物例如C4水稻、将蓝细菌的CO2浓缩机制引入C3植物、增加转运蛋白,以及改善作物根系、优化产物品质和加强作物对环境胁迫的抗性.这篇综述主要考察这些靶标的研究进展,并指出潜在的问题.尽管基因工程是一个强有力的工具,但是人们不应当把新绿色革命成功的希望全部寄托在它上面.一些传统的和非转基因的方法也将在这个革命中发挥重要的作用.这个革命的前途是光明的,但是获得成功所需要的时间可能要比一些人估计的15年长得多.%The potential of the first green revolution has been exploited to a full extent, while the second green revolution is rising. Scientists of all over the world are exploring the possible targets of the new green revolution including improving ribulose-l,5-bisphosphate (RuBP) carboxylase/oxygenase (Rubisco), decreasing pho-torespiratory and respiratory losses, increasing RuBP regeneration capacity, changing C3 plants into C4 plants such as C4 rice, introducing the CO2 concentrating mechanism of cyanobacteria into C3 plants, increasing transporters, as well as improving crop roots, optimizing product quality, and enhancing crop resistances to environmental stresses. This review examines mainly the progress in probing these targets, and points out that the potential problems. Although the gene engineering is a powerful tool, peoples should not put all hopes of success of the new green revolution on it. Some conventional and non-transgenic methods will also play important role in the revolution. The perspective of the revolution is bright, but the time to obtain the success may be much longer than 15 years

  5. Decontamination of body surface

    International Nuclear Information System (INIS)

    There are two important points for an effective application of decontamination procedures. One is the organizing method of responsible decontamination teams. The team should be directed by medical doctor with the knowledge of decontamination of radionuclides. The other point is the place of application of the decontamination. Hospitals and clinics, especially with a department of nuclear medicine, or specialized units such as an emergency medical center are preferable. Before decontamination procedures are initiated, adequate monitoring of the body surface should be undertaken by a competent person in order to demarcate the areas which are contaminated. There are fundamental principles which are applicable to all decontamination procedures. (1) Precautions must always be taken to prevent further spread of contamination during decontamination operations. (2) Mild decontamination methods should be tried before resorting to treatment which can damage the body surface. The specific feature of each contamination varies widely in radionuclides involved, place and area of the contamination, condition of the contaminated skin such as whether the skin is wounded or not, and others. Soap and water are usually good detergents in most cases. If they fail, orange oil cream (SUPERDECONCREAM, available from Tokyo Engineering Co.) specially prepared for decontamination of radionuclides of most fission and corrosion products may be used. Contaminated hair should be washed several times with an efficient shampoo. (author)

  6. The impact of the shale gas revolution on the U.S. and Japanese natural gas markets

    International Nuclear Information System (INIS)

    We investigated whether the increase in the US shale gas production changed the structures of the US and Japanese natural gas markets using market data for the period 2002:5–2012:5. Our analysis consists of a structural break test and market integration analysis. The Bai and Perron structural break test detected a break point of natural gas prices and consumption in 2005 as well as other external shocks – Hurricane Katrina and the Lehman Shock – that are irrelevant to shale gas development. We eliminated the impact of these shocks by separating the data set using the breaks identified in our analysis. We found the breaks skewed the estimation; a market linkage existed between the US and Japanese markets in the original data set, while it did not in the separated data. The vector autoregressive (VAR) model also indicated a significant change before and after the break point; the US market had a one-side influence on the Japanese market before 2005, but the influence disappeared after 2005. Our results implied that the shale gas revolution, triggered by the increase in shale gas production in 2005, caused the change in the relationship between the US and Japanese natural gas markets. -- Highlights: •We investigated the effect of the US shale gas revolution on gas markets. •A break test detected the shale gas revolution occurred in 2005. •The VAR model found a significant change before and after the break point. •The US influence on the Japanese market disappeared after 2005

  7. Agricultural Green Revolution as a driver of increasing atmospheric CO2 seasonal amplitude

    The atmospheric carbon dioxide (CO2) record displays a prominent seasonal cycle that arises mainly from changes in vegetation growth and the corresponding CO2 uptake during the boreal spring and summer growing seasons and CO2 release during the autumn and winter seasons. The CO2 seasonal amplitude has increased over the past five decades, suggesting an increase in Northern Hemisphere biospheric activity. It has been proposed that vegetation growth may have been stimulated by higher concentrations of CO2 as well as by warming in recent decades, but such mechanisms have been unable to explain the full range and magnitude of the observed increase in CO2 seasonal amplitude. Here we suggest that the intensification of agriculture (the Green Revolution, in which much greater crop yield per unit area was achieved by hybridization, irrigation and fertilization) during the past five decades is a driver of changes in the seasonal characteristics of the global carbon cycle. Our analysis of CO2 data and atmospheric inversions shows a robust 15 per cent long-term increase in CO2 seasonal amplitude from 1961 to 2010, punctuated by large decadal and interannual variations. Using a terrestrial carbon cycle model that takes into account high-yield cultivars, fertilizer use and irrigation, we find that the long-term increase in CO2 seasonal amplitude arises from two major regions: the mid-latitude cropland between 25° N and 60° N and the high-latitude natural vegetation between 50° N and 70° N. The long-term trend of seasonal amplitude increase is 0.311 +/- 0.027 per cent per year, of which sensitivity experiments attribute 45, 29 and 26 per cent to land-use change, climate variability and change, and increased productivity due to CO2 fertilization, respectively. Vegetation growth was earlier by one to two weeks, as measured by the mid-point of vegetation carbon uptake, and took up 0.5 petagrams more carbon in July, the height of the growing season, during 2001-2010 than in 1961

    Revolutions in modem world history were also events with ideological significances, and the writing of the history of those revolutions usually displayed some complicated connections with ideologies. There is an obvious transition from "Whiggish paradigm" to "new historiography of the American Revolution" in the historical narration of the American Revolution in the United States. In this process, the Revolution has been transformed from a political revolution led by "the Founding Fathers" into overall revolutions with the ordinary people and marginalized groups as leading roles. In this transformation, ideologies like populism, multicuhuralism, and feminism subtly interacted with historical writing of the Revolution. This reconstructed history of the American Revolution, which is imbued with ideological tints, has moved from the academic periphery to the center, and put new energies into various radicalisms in current America. But however, it is only one of the contested versions of the historical narration of the American Revolution.%世界近现代史上的革命往往也是一种意识形态事件,而革命史写作与意识形态之间有着复杂的关联。美国史学界关于美国革命的历史叙事,经历了从“辉格主义范式”向“新美国革命史学”的转变,这场革命也从“建国之父”领导的政治革命,被改写成了一场由普通民众和边缘群体扮演主角的全面变革。在这一转变中,平民主义、多元文化主义和女性主义等思潮与革命史写作之间发生了微妙的互动。这种经过重构的美国革命史带有浓厚的意识形态色彩,已经从学术的边缘走向了中心,并为当前美国社会各种激进的意识形态提供了新的能量。但它仍只是美国革命史的众多相互竞争的版本中的一个。

    In this research, we study the effects of tourism policy-making in the Pre and Post Islamic revolution (1979) in Iran with a comparative approach. The case study of research is Babolsar in the north of Iran which located on the southern coast of the Caspian Sea. The results of the research show that differences in ideology and values between Pre and Post Islamic Revolution affected on the Tourism Policy-making in Iran. In the case, the jobs and spatial features related to the tourism have been better and increased, but pollution of the coastal environments and shores have been increased. Also the ecotourism opportunities after the revolution have been more attractive for internal tourists than foreigners.

    The ongoing digital revolution is no longer limited to the application of apps on the smart phone for daily needs but starts to affect also our professional life in formulation science. The software platform F-CAD (Formulation-Computer Aided Design) of CINCAP can be used to develop and test in silico capsule and tablet formulations. Such an approach allows the pharmaceutical industry to adopt the workflow of the automotive and aircraft industry. Thus, the first prototype of the drug delivery vehicle is prepared virtually by mimicking the composition (particle size distribution of the active drug substance and of the excipients within the tablet) and the process such as direct compression to obtain a defined porosity. The software is based on a cellular automaton (CA) process mimicking the dissolution profile of the capsule or tablet formulation. To take account of the type of dissolution equipment and all SOPs (Standard Operation Procedures) such as a single punch press to manufacture the tablet, a calibration of the F-CAD dissolution profile of the virtual tablet is needed. Thus, the virtual tablet becomes a copy of the real tablet. This statement is valid for all tablets manufactured within the same formulation design space. For this reason, it is important to define already for Clinical Phase I the formulation design space and to work only within this formulation design space consisting of the composition and the processes during all the Clinical Phases. Thus, it is not recommended to start with a simple capsule formulation as service dosage form and to change later to a market ready tablet formulation. The availability of F-CAD is a necessary, but not a sufficient condition to implement the workflow of the automotive and aircraft industry for developing and testing drug delivery vehicles. For a successful implementation of the new workflow, a harmonization of the equipment and the processes between the development and manufacturing departments is a must. In

    The world is at the dawn of a third industrial revolution, the digital revolution, that brings great changes the world over. Today, computing devices, the Internet, and the World Wide Web are vital technology tools that affect every aspect of everyday life and success. While computing technologies offer enormous benefits, there are equally enormous safety and security risks that have been growing exponentially since they became widely available to the public in 1994. Cybercriminals are increasingly implementing sophisticated and serious hack attacks and breaches upon our nation's government, financial institutions, organizations, communities, and private citizens. There is a great need for computer scientists to carry America's innovation and economic growth forward and for cybersecurity professionals to keep our nation safe from criminal hacking. In this digital age, computer science and cybersecurity are essential foundational ingredients of technological innovation, economic growth, and cybersecurity that span all industries. Yet, America's K-12 education institutions are not teaching the computer science and cybersecurity skills required to produce a technologically-savvy 21st century workforce. Education is the key to preparing students to enter the workforce and, therefore, American K-12 STEM education must be reformed to accommodate the teachings required in the digital age.

    Full Text Available Otpor is discussed in the text as a complex and contradictory new type of social movement, whose members attempted to contribute to the tradition of enlightened reform of social and political life in Serbia, simultaneously in a highly pragmatic and in a creative, possibly even irresponsible manner. After the introduction, analyzed are popular and media narratives on the characteristics of the movement, dilemmas concerning the founding of the movement and meaning of its key symbols, and the Faustian question of goals and consequences of foreign, in particular American influences. Following is a discussion of strategic (non-violent revolution, calculated victimization and tactical (black campaigns, get-out-the-vote campaign roles of Otpor in the coordinated project of ousting Milosevic. Otpor’s role is then re-interpreted in the frame of the ‘electoral revolution’, developed by Valerie Bunce, Sharon Wolchik and Michael McFoul. An assessment of the transformation of Otpor from an active social movement into an exportable blueprint for non-violent political revolutions is offered in lieu of a conclusion.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2014v13n2p303It is the sole topic of conversation throughout Europe. An economic crisis with an underlying crisis of values is devastating everything, while politics has nothing to say. An attempt was made to base the European Unión on a single currency, and the resulting traders’ Europeprevented the desired political project from bearing fruit. Instead of comparing different legal systems before creating a constitution for citizens, we have seen the birth of a new idolatry that is connected with a perverse fatalism. Only macroeconomic figures are considered to be important, while citizens have to suffer because of the actions of a few unscrupulous people who worship profit as well as having legalised usury.Given this situation it is necessary to take all types of precaution, and that is why it is a good idea to see what classical authors have to say. The Enlightenment seems to be a failed project that urgently needs to be restarted. It may be enormously useful to re-read Rousseau, as Cassirer did during the rise of Nazism so that it could be fought on the basis of the history of ideas. His discourse on inequality could not be more relevant now. And the same consideration applies to the genealogical study of the French revolution by Tocqueville. That was the revolution par excellence which Kant described as a symbol of the moral progress of mankind.

    2015-05-01

    Full Text Available This article examines the so-called return of the state in the three Bolivarian Revolutions (Venezuela, Bolivia and Ecuador analyzing the discourses of Hugo Chavez, Evo Morales and Rafael Correa. The idea of a return of the state suggests clearly that if the state was seen as the problem in the 1980s and 1990s, in the processes of the new left in Latin America it has been presented as the solution. However, beyond certain general issues, there have been few analyses that explain how the state has returned in the Bolivarian Revolutions y how this return has redefined the political context and analyze the implications of this return. This article demonstrates how the state has returned in the three cases in relation to two other powerful phenomena: the promise of re-founding the nation and patriotism. It is concluded that the convergence of these three elements –re-foundationalism, the nation and the state– configured a powerful collective identity containing moral and emotional elements which link the leaderships of the three with a reconstituted political community.

    International Nuclear Information System (INIS)

    Based on the lithium-ion technology, the revolution of energy storage is on the way. A first article describes how these new batteries are now introduced into the grid (for example in the USA, in the UK, in Germany, Italy, French islands, China, South Korea, Japan and Australia) and boost energy transition. With this revolution, new regulations and new business models are to be more precisely defined. Clients are asking for energy storage solutions. If new applications seem to boost it, the market remains however complex, unsteady and full of unknowns. In an interview, the Saft chairman comments the sector evolution, fields of application, the success of Tesla batteries, and the bad surprise of a sales drop for energy storage solutions for his company in 2015. The last article discusses how the Li-ion technology extends its domination, indicates the technological differences between fields of application (each application has its cathode), perspectives of improvement for the different involved chemical processes, and evokes safety issues. The article also indicates five technologies which pretend to compete with Li-ion technology (metal lithium polymer, sodium-ion, flow batteries with two electrolytes, lithium-sulphur, and lithium air)

  8. The Sustainability Revolution: A Societal Paradigm Shift

    Directory of Open Access Journals (Sweden)

    Tom R. Burns

    2012-05-01

    Full Text Available This article addresses a question relevant to those interested in the achievement of greater sustainability: What are some of the ways that major societal transformations come about? Firstly, four key mechanisms are identified in the article. Then, I go on to focus on one of these, which has a prominent place in the sustainability revolution that it is argued is now taking place. The question of what are characteristic features of the sustainability revolution is addressed. The ongoing transformations are largely piecemeal, incremental, diffuse—in earlier writings referred to as “organic”. Organic is a more encompassing notion than “grassroots”, since the innovation and transformation processes may be launched and developed at multiple levels by collective agents that in some cases are very large and would not be understood as “grassroots” actors. The article argues that the sustainability revolution shares some features, in particular its organic character, with the early industrial revolution. It concludes by addressing the question of what are the similarities and differences between the sustainability and industrial revolutions.

    2015-02-01

    I argue that the quantum revolution should be seen as an Ian Hacking type of scientific revolution: a profound, longue durée, multidisciplinary process of transforming our understanding of physical nature, with deep-rooted social components from the start. The "revolution" exhibits a characteristic style of reasoning - the hierarchization of physical nature — and developed and uses a specific language - quantum field theory (QFT). It is by virtue of that language that the quantum theory has achieved some of its deepest insights into the description of the dynamics of the physical world. However, the meaning of what a quantum field theory is and what it describes has deeply altered, and one now speaks of "effective" quantum field theories. Interpreting all present day quantum field theories as but "effective" field theories sheds additional light on Phillip Anderson's assertion that "More is different". This important element is addressed in the last part of the paper.

    Krapivskii, P. L.

    The problem of the flow of viscous incompressible fluid past an axisymmetric body with a jet emerging from the rear part of the body is examined. In the framework of the Taylor (1958) jet model, an exact solution is found to the problem of potential flow around a sphere or ellipsoid of revolution with a jet. Calculation of the boundary layer shows that for a relatively small jet momentum it is possible to significantly decrease the size of the separation region on the sphere.

    Full Text Available In desimplifying the logic of colonisation and transition to farming we discuss huntergatherers' and farmer's symbolic structures in the Balkans and Carpathians. Particular attention is paid to the concepts of 'revolution of symbols', 'external symbolic storage' and 'signs of all time'. Our basic premises are (1 that ceramic technology and the principles of fragmentation and accumulationwere not the exclusive domains of farmers and, (2 that the hunter-gatherers' symbolic structures and the process of transition to farmingwere not exclusive and competitive but rather correlative in maintaining control and power within society and over the frameworks of external interactions and exchange networks., but strong parallels between the Near-Eastern and Greek Neolithic.

    Axial body lateropulsion, a phenomenon where the body is pulled toward the side of the lesion, with tendency of falling down, is the well-known transient feature of lateral medullary syndrome. In some cases, axial body lateropulsion occurs without vestibular and cerebellar symptoms (isolated body lateropulsion:[iBL]). Patients with iBL have a lesion located in the spinocerebellar tract, descending lateral vestibulospinal tract, vestibulo-thalamic pathway, dentatorubrothalamic pathway, or thalamocortical fascicle. This review deals with the anatomic basis and clinical significance of iBL. PMID:27001775

The ""astronomical revolution"" was accomplished in three stages, each linked with the work of one man. With Copernicus, the sun became the centre of the universe. With Kepler, celestial dynamics replaced the kinematics of circles and spheres used by Copernicus. With Borelli the unification of celestial and terrestrial physics was completed by abandonment of the circle in favour the straight line to inf

    2013-01-01

    From 1966 to 1983, Argentina underwent a period of political radicalization as fascist regimes used terror to control its citizens and leftist guerrillas resorted to violence to spark revolution. During this politically volatile period, psychiatry transformed from an apolitical clinical specialty into an ideological tool used for both leftist resistance and military oppression. The largest psychiatric organization at the time, the Federación Argentina de Psiquiatras (FAP), became the center for a new politically committed brand of psychiatry in Argentina that united psychoanalysis and community psychiatry with Marxist theory. Though the military targeted and eventually dismantled the FAP and its leftist brand of psychoanalysis and community psychiatry, sectors of the government also paradoxically appropriated and reframed community-based psychiatric perspectives to pathologize leftist subversion and advance their own conservative ideology.

  1. A new class of energy based control laws for revolute robot arms - Tracking control, robustness enhancement and adaptive control

    Science.gov (United States)

    Wen, John T.; Kreutz, Kenneth; Bayard, David S.

    1988-01-01

    A class of joint-level control laws for all-revolute robot arms is introduced. The analysis is similar to the recently proposed energy Liapunov function approach except that the closed-loop potential function is shaped in accordance with the underlying joint space topology. By using energy Liapunov functions with the modified potential energy, a much simpler analysis can be used to show closed-loop global asymptotic stability and local exponential stability. When Coulomb and viscous friction and model parameter errors are present, a sliding-mode-like modification of the control law is proposed to add a robustness-enhancing outer loop. Adaptive control is also addressed within the same framework. A linear-in-the-parameters formulation is adopted, and globally asymptotically stable adaptive control laws are derived by replacing the model parameters in the nonadaptive control laws by their estimates.

    This study was undertaken to determine selamectin residue in dog's blood and in gloves worn while petting dogs after Revolution application. Revolution contains the active ingredient selamectin (a semisynthetic avermectin), which controls endoparasites and ectoparasites, including adult fleas, flea eggs, ticks, heartworms, ear mites, and sarcoptic mange in dogs, for 30 days. Revolution was applied topically on a group of six adult house hold dogs (240 mg selamectin/dog). The gloves worn for 5 min while petting the dogs were collected in glass jars and the blood samples (5 mL/dog) were collected in EDTA tubes at 0 h, 24 h, and 72 h, and at 1, 2, 3, 4, and 5 weeks post-Revolution application for selamectin residue determination. At no time during the study did the dogs show any signs of toxicity, weight loss, or change in body temperature. Extracts of the blood and the gloves were analyzed for selamectin residue using RP-HPLC coupled with a UV detector (246 nm). Selamectin standard used for peak identification and quantitation was purified from Revolution. Selamectin residue was detected in the blood (10.26 +/- 1.06 ng/mL) only at 72 h post-Revolution application, probably due to its poor dermal absorption and rapid elimination from the circulation. In the glove extracts, the highest concentration of selamectin (518.90 +/- 66.80 ppm) was detected 24 h after Revolution application. Transferable residue of selamectin in gloves from dog's coat was detected at a lesser magnitude after 1 week of Revolution application, and that was followed by a further descending trend during the second, third, and fourth weeks. No selamectin residue was detected in the glove extracts after the fifth week. In spite of selamectin's binding to the sebaceous glands of the skin, gloves contained significant transferable residue. Thus, these findings suggest that repeated exposure to selamectin can pose potential health risks, especially to veterinarians, veterinary technologists, dog

    Full Text Available Este artigo pretende focar as relações entre cinema e história nas duas primeiras décadas do século XX no México. O cinema foi apresentado pela primeira vez no país em uma sessão dedicada a Porfirio Díaz. Percebendo seu potencial propagandístico, o ditador logo se converteria na primeira grande estrela do cinema mexicano. O cinema forjava-se como "documento histórico" stricto sensu, num registro da verdade inquestionável. A Revolução redefiniu seu papel, registrando a ebulição pela qual passava a sociedade em documentários que se distanciavam do mero aspecto da curiosidade espetacular para atingir uma verdadeira presença do realizador junto ao cenário político nacional. O desdobramento da Revolução, com a superação da fase insurrecional, e o processo de domesticação do discurso revolucionário no âmbito oficial acabaram por esvaziar o teor de contestação das imagens documentais. A imagem do corpo de Zapata assassinado, que circulou pelo território nacional, é um emblema deste projeto.This article shows the connections between cinema and history in the two first decades in XX century in Mexico.

    Central neural circuits orchestrate the behavioral and autonomic repertoire that maintains body temperature during environmental temperature challenges and alters body temperature during the inflammatory response and behavioral states and in response to declining energy homeostasis. This review summarizes the central nervous system circuit mechanisms controlling the principal thermoeffectors for body temperature regulation: cutaneous vasoconstriction regulating heat loss and shivering and brown adipose tissue for thermogenesis. The activation of these thermoeffectors is regulated by parallel but distinct efferent pathways within the central nervous system that share a common peripheral thermal sensory input. The model for the neural circuit mechanism underlying central thermoregulatory control provides a useful platform for further understanding of the functional organization of central thermoregulation, for elucidating the hypothalamic circuitry and neurotransmitters involved in body temperature regulation, and for the discovery of novel therapeutic approaches to modulating body temperature and energy homeostasis.

    We study the motion of a secondary celestial body under the influence of the corrected gravitational force of a primary. We study the effect of quantum and relativistic corrections to the gravitational potential of a primary body acting on the orbiting body. More specifically, two equations are derived to approximate the perigee/perihelion/periastron time rate of change and its total variation over one revolution (i.e., the difference between the anomalistic period and the Keplerian period) under the influence of the quantum as well as post- Newtonian accelerations. Numerical results have been obtained for the artificial Earth satellite Molnya, Mercury, and, finally, the for the HW Vir c, planetary companion.

    The smuggling of illicit drugs by means of body packing has become a common problem at European airports. Europe is considered to be the fastest growing market for cocaine worldwide, and the air route is the most frequently used method of trafficking cocaine. Smuggling illicit drugs by use of body packing is considered to be a high toxicological hazard because of the risk of leakage or a package bursting. We report about the first case of suicide of a body packer by re-ingesting the content of excreted cocaine packages. The consequence of this case is that the death scene investigation and autopsy assessments in case of a body packer's death should always consider the possibility of re-ingested packages. Detention personnel should be instructed by forensic and criminalistic experts to take preventive measures. PMID:10697780

    Large format (i.e., >25 cm) cranioplasty is a challenging procedure not only from a cosmesis standpoint, but also in terms of ensuring that the patient's brain will be well-protected from direct trauma. Until recently, when a patient's own cranial flap was unavailable, these goals were unattainable. Recent advances in implant computer-aided design and 3-dimensional (3-D) printing are leveraging other advances in regenerative medicine. It is now possible to 3-D-print patient-specific implants from a variety of polymer, ceramic, or metal components. A skull template may be used to design the external shape of an implant that will become well integrated in the skull, while also providing beneficial distribution of mechanical force in the event of trauma. Furthermore, an internal pore geometry can be utilized to facilitate the seeding of banked allograft cells. Implants may be cultured in a bioreactor along with recombinant growth factors to produce implants coated with bone progenitor cells and extracellular matrix that appear to the body as a graft, albeit a tissue-engineered graft. The growth factors would be left behind in the bioreactor and the graft would resorb as new host bone invades the space and is remodeled into strong bone. As we describe in this review, such advancements will lead to optimal replacement of cranial defects that are both patient-specific and regenerative. PMID:26171578

  1. Dissent, revolution and liberty beyond Earth

    CERN Document Server

    2016-01-01

    This volume provides an in-depth discussion on the central question – how can people express and survive dissent and disagreement in confined habitats in space? The discussion is an important one because it could be that the systems of inter-dependence required to survive in space are so strong that dissent becomes impossible. John Locke originally said that people have a right to use revolution to overthrow a despotic regime. But if revolution causes violence and damage that causes depressurisation with the risk of killing many people, is it even permissible to have a revolution? How then are people to express their liberty or dissatisfaction with their rulers? The emergence of structures of dissent and disagreement is an essential part of the construction of a framework of liberty in space (revolution is just the extreme example) and thus the topic deserves in-depth and immediate attention. Even today, the way in which we assemble organisations and corporations for the government and private exploration o...

  3. Preliminary Design of Debris Removal Missions by Means of Simplified Models for Low-Thrust, Many-Revolution Transfers

    Directory of Open Access Journals (Sweden)

    Federico Zuiani

    2012-01-01

    Full Text Available This paper presents a novel approach for the preliminary design of Low-Thrust, many-revolution transfers. The main feature of the novel approach is a considerable reduction in the control parameters and a consequent gain in computational speed. Each spiral is built by using a predefined pattern for thrust direction and switching structure. The pattern is then optimised to minimise propellant consumption and transfer time. The variation of the orbital elements due to the thrust is computed analytically from a first-order solution of the perturbed Keplerian motion. The proposed approach allows for a realistic estimation of ΔV and time of flight required to transfer a spacecraft between two arbitrary orbits. Eccentricity and plane changes are both accounted for. The novel approach is applied here to the design of missions for the removal of space debris by means of an Ion Beam Shepherd Spacecraft. In particular, two slightly different variants of the proposed low-thrust control model are used for the different phases of the mission. Thanks to their low computational cost they can be included in a multiobjective optimisation problem in which the sequence and timing of the removal of five pieces of debris are optimised to minimise propellant consumption and mission duration.

    Cooper, Luke William Roger

    2013-01-01

    This thesis addresses the paradox of capitalist market reform being introduced by a politically undefeated communist state in China. It does so by developing an historical account of the Chinese polity’s relationship with the modern world. Chapter one offers a critique of existing explanations; these tend to focus narrowly on the immediate circumstances surrounding the decision to reform and thereby eschew analysis of the specific dynamics of the Chinese Revolution. In so doing, they also ...

  8. The 'Shale Gas Revolution'. Hype and Reality

    International Nuclear Information System (INIS)

    The 'shale gas revolution' - responsible for a huge increase in unconventional gas production in the US over the last couple of years - is creating huge investor uncertainties for international gas markets and renewables and could result in serious gas shortages in 10 years time. This report casts serious doubt over industry confidence in the 'revolution', questioning whether it can spread beyond the US, or indeed be maintained within it, as environmental concerns, high depletion rates and the fear that US circumstances may be impossible to replicate elsewhere, come to the fore. Investor uncertainty will reduce investment in future gas supplies to lower levels than would have happened had the 'shale gas revolution' not hit the headlines. While the markets will eventually solve this problem, rising gas demand and the long lead-in-times on most gas projects are likely to inflict high prices on consumers in the medium term. The uncertainties created by the 'shale gas revolution' are also likely to compound existing investor uncertainty in renewables for power generation in the aftermath of Copenhagen. The serious possibility of cheap, relatively clean gas may threaten investment in more expensive lower carbon technologies.

    Full Text Available This paper traces successful and unsuccessful attempts to shape the meanings of the video game Dance Dance Revolution, specifically with reference to what "dancing" means in this context, as the game moves between various interested parties - game developers, players, Internet forum participants, and other media producers. Drawing on Actor-Network Theory and the network analyses of Manuel Castells, the paper reconstructs the forces shaping players' stylistic decisions through an analysis of dance game machines and software, and of a single forum thread on DDRFreak.com, a major website in the dance game community. The paper asks who decides how DDR players dance and at what times? Are the decisions about play made in the development meeting, the arcade, competitions, online or around the home console? Globally, how do some regions or groups emerge as experts or leaders in play style? Analysis indicates that within the United States, Californian players from major cities dominate discussion, supported by the global flows of people, resources, and capital through the state. The dominant players support their stated norms for play through recourse to mainstream conceptions of masculinity, rap music and associated styles of dance.

  10. Railgun launch of small bodies

    The small body launching using gas or plasma faces the fundamental problem caused by excess energy loss due to great wall surface/volume of the barrel ratio. That is why the efficiency of the plasma armature (PA) railgun acceleration is maximum for 8--10 mm-size bodies and drops as their size decreases. For the nuclear fusion applications, where {number_sign}1--2 mm-size pellets at 5--10 km/s velocity are desirable, one is forced to search for compromise between the body size (3--4 mm) and its velocity (3 km/s). Under these conditions, EM launchers did not demonstrate an advantage over the light-gas guns. When elaborating the {number_sign}1 mm railgun, the authors made use of the ideology of the body launching at constant acceleration close to the body strength or the electrode skin-layer explosion limits. That shortened the barrel length sufficiently. The system becomes highly compact thus permitting rapid test of new operation modes and different modifications of the design including the magnetic field augmentation. As a result of these refinements, the difficulties caused by the catastrophic supply of mass ablated from the electrodes were overcome and regimes of {number_sign}1 mm body non-sabot speed-up to 4.5 km/s were found. Potentialities of the small system created are far from being exhausted.

    Full Text Available This paper examines how media exposure, self-esteem, and religiosity influence body image of Pakistan consumers. The underpinning of this study is based on Social Comparison Theory with two additional variables (religiosity and self-esteem for understanding understand consumer attitude towards body image. A self-administered questionnaire was used. 193 persons responded at mall intercepts. The Conceptual framework was empirically tested through SEM. A positive relationship between exposure to media and body image was found while negative influence was found between self-esteem and body image. No relationship was found between religiosity and body image. The results showed mixed outcomes as compared to past studies. The scope of this study is limited to one city only and hence the finding could not be generalized. Future researcher may use a larger sample drawn throughout Pakistan, and by examining whether body image perception varies ethnically, age and gender. Media exposure is affecting the traditional norms and values of Pakistan culture and body image. The obsessions of the media and thin body image have to be controlled and this requires policy changes. Corporate sector might take initiative by not selecting ultra-thin models. They might also sponsors public service messages showing ill effects of being ultra-thin, and showing that the ultra-thin models are not real but is results of artworks and camera angles. Social Comparison Theory with two addition variable religiosity and self-esteem has been successfully extended/empirically tested in the domain of Pakistan culture.

    2015-07-01

    Full Text Available Focusing on a study of Taiwan’s United News Daily archive and the shifting discourses of the Green Revolution and the organic food movement, the project analyzes the narrative frameworks produced on the apple snail (Pomacea canaliculata in Taiwan. Apple snail has become invasive to many East Asian countries since the 1980s; it is considered among the world’s 100 most invasive species. During the era of the Green Revolution, the economy of killing the apple snail with pesticide was generated by a narrative of how greedy merchants imported invasive apple snail and led to the systematic disruption of Taiwan’s ecology. The paper explores how the organic food movement responded to and was shaped by such a narrative of innocence lost, and emphasizes the importance of going beyond the hyper-real narratives of irreparable ecological destructions by recognizing sites of memories left behind by global capital flow.

  5. The Industrial Revolution and Birth of the Anti-Mercantilist Idea:Epistemic Communities and Global Leadership

    Directory of Open Access Journals (Sweden)

    Daniel J. Whiteneck

    2015-08-01

    Full Text Available This paper seeks to offer a new perspective on the linkage between global leadership and the role of epistemic communities in international relations. The issue of bilateral trade liberalization between Great Britain and its trading partners rose to prominence on the global agenda in the 1700s by the efforts of British political economists and merchants. These efforts were prompted by changes in economic relations brought about by the Industrial Revolution and its impact on the mercantile system. While this group was small in number and its interactions rudimentary by 20th Century standards, it nonetheless met the qualifications specified by many scholars. It is further argued that such communities are linked to the exercise of global leadership in the long cycle model's phases of agenda setting and coalition building. They arc started and based in the global leader, and arc nurtured by the relatively open social and political structures of that leader. Evidence supporting this argument strengthens the long cycle model's explanatorypower with regard to agenda setting, coalition creation, and the role of innovative solutions to global problems, and makes preeminence in knowledge -based communities another dimension of global leadership.

  6. Log spiral of revolution highly oriented pyrolytic graphite monochromator for fluorescence x-ray absorption edge fine structure

    International Nuclear Information System (INIS)

    We have constructed an x-ray monochromator based on a log spiral of revolution covered with highly oriented pyrolytic graphite. Such a monochromator is used for obtaining x-ray absorption edge fine structure by the fluorescence method, and is particularly useful for measuring the fine structure of dilute element A in a concentrated matrix of element B, where B is to the left of A in the Periodic Table. Using the log spiral monochromator, we measure good Cr x-ray fine structure in an alloy of 1% Cr in a V matrix, whereas the corresponding spectrum is severely distorted by the V background if nonmonochromatized fluorescence is used. We also obtain excellent rejection of Mn fluorescence relative to Cr fluorescence in a Cr80Mn20 alloy, and can tune the monochromator such that the entire Mn step height is significantly smaller than the Cr x-ray absorption edge fine structure oscillations for this system.

    The importance of commensal microbes for human health is increasingly recognized, yet the impacts of evolutionary changes in human diet and culture on commensal microbiota remain almost unknown. Two of the greatest dietary shifts in human evolution involved the adoption of carbohydrate-rich Neolithic (farming) diets (beginning ∼10,000 years before the present) and the more recent advent of industrially processed flour and sugar (in ∼1850). Here, we show that calcified dental plaque (dental calculus) on ancient teeth preserves a detailed genetic record throughout this period. Data from 34 early European skeletons indicate that the transition from hunter-gatherer to farming shifted the oral microbial community to a disease-associated configuration. The composition of oral microbiota remained unexpectedly constant between Neolithic and medieval times, after which (the now ubiquitous) cariogenic bacteria became dominant, apparently during the Industrial Revolution. Modern oral microbiotic ecosystems are markedly less diverse than historic populations, which might be contributing to chronic oral (and other) disease in postindustrial lifestyles. PMID:23416520

He goes out into the garden at Croisset: lime trees, then poplars, then the Seine. An outbuilding on a bank beside some water. He’s finished Part One of Madame Bovary.That Sunday, he would write Louise Colet how at dawn on Friday he’d felt strong, serene, blest in sense and in purpose. The dawn wind does him good. He has a tired fat handsome face, a calm fat handsome face. He loves writing. He loves the world.“Deprived of a party, country, house, personal life, etc., he made writing his only reason to live, and it grips one’s heart how seriously he takes the written world.” These words of Pasolini’s pertain to Gombrowicz. But they might just as well be applied to Flaubert, and one’s heart would not be gripped any less, maybe more. For, if Flaubert had a personal life (as Gombrowicz did after all, but then Pasolini always goes very fast, he pretended not to have one; just as he pretended to have no house, country, freedom, mother named Caroline, orphaned niece also named Caroline, Seine at the end of the path, rolling on before his eyes, sharecroppers’ hillside groves, heaps of disciples and flatterers, well-meaning interns hard at work on his behalf in the corridors of Paris journals and salons: all things Gombrowicz truly did not have, that he, Flaubert, had.

    The feeling of “ownership” over an external dummy/virtual body (or body part) has been proven to have both physiological and behavioural consequences. For instance, the vision of an “embodied” dummy or virtual body can modulate pain perception. However, the impact of partial or total invisibility of the body on physiology and behaviour has been hardly explored since it presents obvious difficulties in the real world.

    Full Text Available It can be said that French Revolution, broke out in 1789, affected Europe deeply in freedom, equality, particularly with the ideas of nationalism. New values were introduced with the nationalism. With the new symbols, national states sought to give the community a new identity. Within this new formation, political powers in the adoption by the community and in its efforts to provide legitimacy, transfer tools to future generations are extremely important. In this context, the teaching of history is of great importance. In this study, a field survey was conducted on the lesson called Atatürk’s Principles and History of Revolution which have aims such as being able to teach the stages of foundation of the Republic of Turkey and to transfer the information to future generations. In that study, it was also aimed to find out information about the methodology of the lesson which has great importance on the development of the consciousness of Nationalism and citizenship and about founder of Turkish republic Ataturk. In this study a survey model was used. The students, who were studying in Kırşehir in the 2010-2011 academic years, set the population of the survey. To collect data in the survey, a questioner is used with the aim of discovering the opinions of the students about the course of “Atatürk’s Principles and History of Revolution. In the analysis, the t-test is used and the method of single factor variance analysis (ANOVA and percentage frequency is used.

  15. EDITORIAL: Permanent revolution - or evolution?

    Science.gov (United States)

    Dobson, Ken

    1998-03-01

    Honorary Editor It was that temporary Bolshevik Leon Trotsky who developed the principle of `permanent revolution', a principle that perhaps characterizes the recent history of education in (south) Britain more than does, say, principles traditionally associated with the Conservative or Labour parties. As this editorial is being written, changes are being made to primary school education, and the long-awaited details of the post-Dearing reorganizing of post-16 education are yet to hit the overful bookshelves and filing cabinets of school heads and examination board officials. But something unique has happened recently which might have surprised even Trotsky. The Secretary of State for Education has set up targets for primary school pupils' attainment and threatened (or promised) to resign if they are not met within the lifetime of our newly elected parliament. Of course, if Mr Blunkett is still in a position to resign at that stage he will have been the longest serving Secretary of State since time immemorial. But we should not carp: this is truly a revolutionary idea. Not the promise to resign - although this idea is not so fashionable now as it once was. The revolutionary idea is that a major change to an educational process is actually being made that carries with it a predicted and testable outcome. By contrast, when school physics was refreshed a generation ago by the introduction of Nuffield courses at both pre- and post-16 stages, no `targets' were set. I and many other physics teachers certainly preferred teaching these to teaching their predecessor syllabuses, and might even dare to assert that the pupils liked them too. But we still don't really know whether or not they learned more - or even better - physics. Very little happened as far as the outside world was concerned: the usual fraction of students gave up physics at the usual ages, and those who were examined didn't really get a better reward for their more up-to-date and more enjoyably learned

    2011-01-01

    At this beginning of the 21st century, the situation of physics is not without analogy with that which prevailed a hundred years ago, with the outset of the double scientific revolution of relativity and quanta. On the one hand, recent progress of observational cosmology makes think that one has discovered a new universal constant, perhaps as fundamental as the velocity of light or the Planck's constant, the cosmological constant, which could explain the acceleration of the expansion of the universe. On the other hand, just like the efforts of Planck and Einstein to reconcile thermodynamics and the electromagnetic theory of light led to the operational beginning of quantum physics, the unexpected discovery of bonds between thermodynamics and general relativity makes to foresee new concepts, perhaps heralding a new scientific revolution, like that of holography and leads to consider a "thermodynamic route towards quantum cosmology." We will discuss the possible implications of these observational and theoretic...

    1997-01-01

    The objective of this study was to evaluate the use of hip height and width, body condition score, and relevant demographic information to predict body weight (BW) of dairy cows. Seven regression models were developed from data from 972 observations of 554 cows. Parity, hip height, hip width, and...... body condition score were consistently associated with BW. The coefficients of multiple determination varied from 80 to 89%. The number of significant terms and the parameter estimates of the models differed markedly among groups of cows. Apparently, these differences were due to breed and feeding...... regimen. Results from this study indicate that a reliable model for estimating BW of very different dairy cows maintained in a wide range of environments can be developed using body condition score, demographic information, and measurements of hip height and hip width. However, for management purposes...

  1. Women, Modernization and Revolution in Iran

    OpenAIRE

    This paper examines the contradictory nature of women's support for the Iranian revolution, which severely restricted women's legal and social rights. An analysis of the possibilities and limitations of the pre-revolutionary reforms points to the lack of necessary conditions for the development of an autonomous feminist movement. In the absence of such a movement, the issues of women's oppression were subsumed and muted in the anti-imperialist struggle.

  2. The Nineteenth-Century Revolution in Astronomy

    The term "revolution" in scientific contexts usually refers either to the beginnings of modern western science in the sixteenth and seventeenth centuries, or to the two great revolutions of early twentieth century physics. Comparison of what was known at the beginning of the nineteenth century with what was known at the end, however, shows that century to have been one of transformation in astronomy, and in the other sciences, that amounts to "revolution". Astronomers in 1800 knew neither the nature of the Sun nor the distances of the stars. Developments in instrumentation enabled the first determinations of stellar parallax in the 1830s, and later enabled the solar prominences to be studied outside the brief momemnts of total eclipses. The development of photography and of spectroscopy led to the birth of observational astrophysics, while the greater understanding of the nature of heat and the rise of thermodynamics made possible the first attempts to investigate the theory of stellar structure. Nothing was known in 1800 of extra-galactic objects apart from some tentative identifcations by William Herschel but, by the end of the century, the discovery of the spiral structure of some nebulae had led some to believe that these were the "island universes" about which Kant had speculated. Of course, astrophysics and cosmology would be much further developed in the twentieth century and those of us whose careers spanned the second half of that century look back on it as a "golden age" for astronomy; but the nineteenth century was undoubtedly a time of rapid transformation and can be reasonably described as as one of the periods of revolution in astronomy.

    1 War has been part of Europe for many years and has been the constant occupation of her turbulent peoples. Nevertheless, not one of them since the Thirty Years' War has been so catastrophic as the wars of the present century. Yet the reason is not to be sought in war itself, but in its conduct as related to the great revolutions since 1789: the decay of aristocracy and the advent of democracy, the developments of industry and capitalism, the emergence of the masses and of socialism, the prog...

    This article gives a brief introduction to the English Revolution and describes a detailed study of influence, as well as the explanation of a representative and constitutional government. The English Revolution which happened in Britain is a histori-cal event of great influence. It abolished the autarchic system of king and began to rule the society by law. We can conclude that it created good political conditions for Britain to become a kingdom of modern civilization.

    Technological change was unskilled-labour-biased during the early Industrial Revolution of the late eighteenth and early nineteenth centuries, but is skill-biased today. This fact is not embedded in extant unified growth models. We develop a model of the transition to sustained economic growth which can endogenously account for both these facts, by allowing the factor bias of technological innovations to reflect the profit-maximising decisions of innovators. Endowments dictated that the initi...

    Democracy has been the primary focus of our efforts to understand the impact of domestic institutions on processes of international conflict. In this article, we examine how a particular nondemocratic regime type, postrevolutionary states, affects military capabilities and war outcomes. Drawing on scholarship that conceptualizes revolutions as a unique class of modernizing events that result in stronger state structures, we argue that postrevolutionary states should be better able to mobilize...

    The basic tectonic framework of continental East Asia was produced by a series of nearly contemporaneous orogenic events in the late Middle Jurassic to Early Cretaceous. Commonly, the Late Mesozoic orogenic processes were characterized by continent-continent collision, large-scale thrusting, strike-slip faulting and intense crustal shortening, crustal thickening, regional anatexis and metamorphism, followed by large-scale lithospheric extension, rifting and magmatism. To better understand the geological processes, this paper reviews and synthesizes existing multi-disciplinary geologic data related to sedimentation, tectonics, magmatism, metamorphism and geochemistry, and proposes a two-stage tectono-thermal evolutionary history of East Asia during the late Middle Jurassic to Early Cretaceous (ca. 170-120 Ma). In the first stage, three orogenic belts along the continental margins were formed coevally at ca. 170-135 Ma, i.e., the north Mongol-Okhotsk orogen, the east paleo-Pacific coastal orogen, and the west Bangong-Nujiang orogen. Tectonism related to the coastal orogen caused extensive intracontinental folding and thrusting that resulted in a depositional hiatus in the Late Jurassic, as well as crustal anatexis that generated syn-kinematic granites, adakites and migmatites. The lithosphere of the East Asian continent was thickened, reaching a maximum during the latest Jurassic or the earliest Cretaceous. In the second stage (ca. 135-120 Ma), delamination of the thickened lithosphere resulted in a remarkable (>120 km) lithospheric thinning and the development of mantle-derived magmatism, mineralization, metamorphic core complexes and rift basins. The Middle Jurassic-Early Cretaceous subduction of oceanic plates (paleo-Pacific, meso-Tethys, and Mongol-Okhotsk) and continent-continent collision (e.g. Lhasa and Qiangtang) along the East Asian continental margins produced broad coastal and intracontinental orogens. These significant tectonic activities, marked by

    In four sequences, standing beside a huge steam wheel, Simon Schaffer discusses some of the things that are needed for the development of the steam revolution. These include reliable cylinders (from gun manufacture), good boilers ( from brewing), and feed-back mechanisms (from clocks). Only in England did one have the concentration of skills and the suitable social mobility to allow this to happen in the later seventeenth and early eighteenth century.

    We examine the importance of geographical proximity to coal as a factor underpinning comparative European economic development during the Industrial Revolution. Our analysis exploits geographical variation in city and coalfield locations, alongside temporal variation in the availability of coal-powered technologies, to quantify the effect of coal availability on historic city population sizes. Since we suspect that our coal measure could be endogenous, we use a geologically derived measure as...

    The observed diversity of dinosaurs reached its highest peak during the mid- and Late Cretaceous, the 50 Myr that preceded their extinction, and yet this explosion of dinosaur diversity may be explained largely by sampling bias. It has long been debated whether dinosaurs were part of the Cretaceous Terrestrial Revolution (KTR), from 125–80 Myr ago, when flowering plants, herbivorous and social insects, squamates, birds and mammals all underwent a rapid expansion. Although an apparent explosio...

  17. Health and the urban environment: revolutions revisited

    2009-05-15

    From cholera pandemics to smog episodes, urban development driven by narrow economic interests has shown itself to be a serious threat to human health and wellbeing. Past revolutions in sanitation and pollution control demonstrate that social movements and governance reforms can transform an urban health penalty into a health advantage. But many environmental problems have been displaced over time and space, and never truly resolved. Health concerns need once again to drive an environmental agenda – but this time it must be sustainable over the long haul, and globally equitable. With the global economic crisis raising the ante, what's needed is no less than a revolution in environmental justice that puts health, not economics, at the core of its values.

  18. Rigid body dynamics of mechanisms

    CERN Document Server

    Hahn, Hubert

    2003-01-01

    The second volume of Rigid Body Dynamics of Mechanisms covers applications via a systematic method for deriving model equations of planar and spatial mechanisms. The necessary theoretical foundations have been laid in the first volume that introduces the theoretical mechanical aspects of mechatronic systems. Here the focus is on the application of the modeling methodology to various examples of rigid-body mechanisms, simple planar ones as well as more challenging spatial problems. A rich variety of joint models, active constraints, plus active and passive force elements is treated. The book is intended for self-study by working engineers and students concerned with the control of mechanical systems, i.e. robotics, mechatronics, vehicles, and machine tools. The examples included are a likely source from which to choose models for university lectures.

    Full Text Available The main issue dealt with in this theoretical paper is the explanation of the starting scientific and democratic revolution both in the educative field and in the educative research. In addition, evidence-based arguments are included to provide validity of some affirmations. The first section argues that the social sciences are the daughters and an essential part of democracy. A few historical arguments about the way in which the dominant classes have slowed down the scientific progress and the development of people that make it possible. In the second section, it is analyzed the opposition of feudal universities to this unstoppable beginning of what could be called the scientific and democratic revolution. At the same time, we deal with its ambivalent character requiring to be supported and to be criticized so that it can be improved. In the third section, we expound the way in which this progress has provide some conditions that makes it possible to overcome the strong gender-based violence happening in our institutions of higher education and makes it also possible that women who were persecuted are now transforming our universities. Influences and criticism to our university feudalism, made by social movements such as the named 'Spanish Revolution', appear in the fourth section. In the fifth and last section, we offer a proposal to promote the scientific, democratic, and revolutionary approach of the university.

    Full Text Available The .Industrial Engineer is caught between the Industrial Revolution and the Information revolution. He is confronted with choosing between pragmatic improvements in productivity and efficiency of a single operation or the opportunistic modelling and reshaping of the networked "virtual enterprise" to become more competitive in a global marketplace . The diagram below depicts the different extremes of the Industrial Engineering timeline. This implies that the two societies (Industrial and information might have conflicting characteristics which requires careful repositioning of the Industrial Engineer to ensure that the benefits that can be obtained from the two societies are maximised.

    This paper documents the development of Industrial engineering , then evaluates the nature of the much publicized Information revolution and its impact on society. In order to establish the nature and composition of contemporary Industrial Engineering in the 1990' s, an analysis and categorization of the literature in four journals for the last two years are performed. This is enhanced with an INTERNET search into Industrial Engineering Research and developments that are currently under development.
