The Shaping of Public Economic Discourse in Postwar America: The 1947 Meat Shortage and Franco Modigliani’s Meat Plan
2015
Abstract This paper discusses the American debate over price controls and economic stabilization after World War II, when the transition from a war economy to a peace economy was characterized by bottlenecks in the productive system and shortages of food and other basic consumer goods, directly affecting the living standard of the population, the public opinion, and political discourse. Specifically, we will focus on the economist Franco Modigliani and his proposal for a “Plan to meet the problem of rising meat and other food prices without bureaucratic controls.” The plan prepared by Modigliani in October 1947 was based on a system of taxes and subsidies to foster a proper distribution of …
Tradition and modernity: new sound proposals from the music schools of the federation of musical societies of the valencian community
2019
Background: The Federation of Musical Societies of the Valencian Community (FSMCV) is a democratic association created 50 years ago, which represents and supports the 550 associations that make it up, with the aim of promoting, disseminating and teaching music. It promotes associationism and provides society with a way of developing cultural articulation, mainly developing its activities within the Valencian Community, although its national and international activity is very remarkable. Methodology: This article based on a prospective study using a qualitative methodology analyzes one of the proposals made to commemorate the 50th anniversary of the FSMCV through the use and application of t…
Categories, Musical Instruments, and Drawings: A Unification Dream
2019
The mathematical formalism of category theory allows to investigate musical structures at both low and high levels, performance practice (with musical gestures) and music analysis. Mathematical formalism can also be used to connect music with other disciplines such as visual arts. In our analysis, we extend former studies on category theory applied to musical gestures, including musical instruments and playing techniques. Some basic concepts of categories may help navigate within the complexity of several branches of contemporary music research, giving it a unitarian character. Such a 'unification dream,' that we can call 'cARTegory theory,' also includes metaphorical references to topos th…
Política del ruido. En los límites de la comunicación musical
2016
Este artículo se basa en la idea de cómo la comunicación musical activa no solo elementos musicales sino culturales y sociales. Como práctica social, la música muestra tanto su poder comunicativo como los límites de la comunicación (entendida como un intercambio de mensajes y significados). En este sentido, el ruido se presenta como un factor de disrupción en el circuito semiótico y en las relaciones sociales. La cuestión del ruido se trata como un aspecto liminar del sonido y la música, como puede observarse en diversos ejemplos tomados de la vanguardia (ruidismo) hasta la música popular contemporánea (noise), pasando por géneros musicales particulares como el punk-rock o la música tecno.
Can hydrophobic interactions be correctly reproduced by the continuum models?
1996
The ability of the continuum models to describe hydrophobic interactions is investigated. In this work we have studied the interactions between two methane molecules in aqueous solution by means of a continuum model. The resulting potential of mean force is in good agreement with those obtained using Monte Carlo and molecular dynamics techniques. The three energy contributions appearing in the continuum energy partition (electrostatic, dispersion−repulsion, and cavitation) have been analyzed. The cavitation free energy plays the most important role of the three, determining the existence of an energy barrier between the contact minimum and the separated methane monomers. This barrier, which…
Looking More Closely at the Rabinovich-Fabrikant System
2016
Recently, we looked more closely into the Rabinovich–Fabrikant system, after a decade of study [Danca & Chen, 2004], discovering some new characteristics such as cycling chaos, transient chaos, chaotic hidden attractors and a new kind of saddle-like attractor. In addition to extensive and accurate numerical analysis, on the assumptive existence of heteroclinic orbits, we provide a few of their approximations.
Influence of the Electromagnetic, G-Jitter or Thermocapillary Forces on the Stability of the Stationary Buoyancy Convection
1992
Microgravity conditions seem to be very useful for crystal growth processes. Reduced gravitational force strongly weakens the buoyancy convection, so the convective oscillations in the melt become impossible [1]. This is the main reason of numerous attempts to obtain monocrystal materials with homogeneous internal structure in microgravity. On the other hand for non-isothermal fluid in microgravity conditions other driving forces become more significant than on the Earth. The main of them are thermocapillarity and g-jitter. The thermocapillary forces exist on the non-uniformly heated free liquid surfaces and cause motion of the fluid. The g-jitter appears in space unavoidably because of the…
Charged colloidal particles in a charged wedge: do they go in or out?
2008
Using real-space microscopy experiments, theory and computer simulation, we study the behaviour of highly charged colloidal particles which are confined between two highly charged plates forming a wedge geometry. Under low salt conditions it is experimentally observed that colloidal particles accumulate in the cusp of a wedge to form dense fluid or crystalline ordered structures. This behaviour is found for various cell geometries, salt concentrations and gravitational strengths, and even stays stable when additional convection is present in the system. An effort is made to understand this effect qualitatively on the basis of linear screening theory. For a single macro-ion, linear screening…
Time-dependent simulation of Czochralski silicon crystal growth
1997
We have developed a detailed mathematical model and numerical simulation tools based on the streamline upwind/Petrov-Galerkin (SUPG) finite element formulation for the Czochralski silicon crystal growth. In this paper we consider the mathematical modeling and numerical simulation of the time-dependent melt flow and temperature field in a rotationally symmetric crystal growth environment. Heat inside the Czochralski furnace is transferred by conduction, convection and radiation, Radiating surfaces are assumed to be opaque, diffuse and gray. Hence the radiative heat exchange can be modeled with a non-local boundary condition on the radiating part of the surface. The position of the crystal-me…
Onset of convection in a vertical porous cylinder with a permeable and conducting side boundary
2015
Abstract The onset of natural convection in a vertical porous cylinder saturated by a fluid is studied. The lateral confinement of the porous cylinder is due to an external porous medium having a permeability much smaller than that of the cylinder. Thus, the vertical side boundary of the cylinder is permeable and constrained by given pressure and temperature distributions. The lower and upper plane boundaries of the cylinder are impermeable walls. The lower wall is subject to a uniform heat flux, while the upper wall has a uniform temperature. The basic motionless state displays a uniform and vertical temperature gradient oriented downward. The linear stability analysis is carried out by us…
