cities are the picture of the outbreak of expressions of the processes of accumulation, consumption, circulation and production of goods plus the interaction of individuals, socially represented in ...classes. In general, from the adjectives and their derivations a city is constructed that articulates through its actors in constructing itself locally viable. From this perspective, this essay aims to analyze, briefly, the relations between urban development and creative economy. For this, methodologically, it is worth of a bibliographical revision about the fundamental concepts of the urban development and creative economy and repercussions of this relation. In this line, it is thought that the city when it uses creativity as an adjective must be conceived in a logic of space built to meet the particularities of the territory. And, not for the logic of competition and standardization of territory designed for global competition. The purpose of culture and creativity must break with dependence in the context of development, especially as regards the way and process as the city and its urbanization are constituted and consolidated.A Criatividade e a Cultura como Elementos do Desenvolvimento UrbanoResumo: as cidades são o retrato da eclosão das expressões dos processos de acumulação, consumo, circulação e produção de bens somados a interação de indivíduos, socialmente representados em classes. Em geral, a partir dos adjetivos e suas derivações se constrói uma cidade que se articula por meio de seus atores em construir-se viável localmente. Nessa perspectiva, este ensaio visa analisar, sucintamente, as relações entre desenvolvimento urbano e economia criativa. Para tal, metodologicamente, vale-se de uma revisão bibliográfica acerca dos conceitos fundamentais do desenvolvimento urbano e economia criativa e repercussões dessa relação. Nessa linha, pensa-se que a cidade quando emprega a criatividade como adjetivo deve ser concebida numa lógica do espaço construído para atender as particularidades do território. E, não para a lógica da competição e padronização do território pensada para a competição global. O propósito da cultura e da criatividade deve romper com a dependência no contexto do desenvolvimento, especialmente, no que tange ao modo e processo como a cidade e sua urbanização se constituem e consolidam.La Creatividad y la Cultura como Elementos del Desarrollo UrbanoResumen: las ciudades son el retrato de la eclosión de las expresiones de los procesos de acumulación, consumo, circulación y producción de bienes sumados a la interacción de individuos, socialmente representados en clases.

This paper briefly reviews the next generations of nuclear reactors and the perspectives of development of nuclear energy. Advanced reactors will progressively replace the existing ones during the ...next two decades. Future systems of the fourth generation are planned to be built beyond 2030. These systems have been studied in the framework of the “Generation IV” International Forum. The goals of these systems is to have a considerable increase in safety, be economically competitive and produce a significantly reduced volume of nuclear wastes. The closed fuel cycle is preferred.
A Compton polarimeter has been installed in Hall A at Jefferson Laboratory. This Letter reports on the first electron beam polarization measurements performed during the HAPPEX experiment at an ...electron energy of 3.3 GeV and an average current of 40 μA. The heart of this device is a Fabry–Perot cavity which increased the luminosity for Compton scattering in the interaction region so much that a 1.4% statistical accuracy could be obtained within one hour, with a 3.3% total error.

A new kind of Compton polarimeter using a resonant Fabry–Pérot cavity as a power buildup for the photon beam is proposed. A prototype of such a cavity is described, along with the results obtained in ...terms of source to be used in a Compton scattering polarimeter.
We have measured the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from the proton. The kinematic point (theta_lab = 12.3 degrees and Q^2=0.48 (GeV/c)^2) is ...chosen to provide sensitivity, at a level that is of theoretical interest, to the strange electric form factor G_E^s. The result, A=-14.5 +- 2.2 ppm, is consistent with the electroweak Standard Model and no additional contributions from strange quarks. In particular, the measurement implies G_E^s + 0.39G_M^s = 0.023 +- 0.034 (stat) +- 0.022 (syst) +- 0.026 (delta G_E^n), where the last uncertainty arises from the estimated uncertainty in the neutron electric form factor.

This paper describes the project of a 15–30 GeV CW electron accelerator to study how color forces build up hadrons from quarks and gluons. ELFE@DESY combines a section of the TESLA linear collider ...and the HERA ring to produce a high luminosity continuous electron beam for fixed target experiments.
The 3s radial wave function R (r ) has been determined by electron scattering from exp 206 Pb and exp 205 Tl. The shape of R (r ) in the central region of the nucleus is used to test the validity of ...the independent-particle shell model at large nuclear density. 15 ref.--AA
We have perfromed high-precision measurements of {sup 3}He charge and magnetic form factors up to {ital Q}{sup 2}=1 (GeV/{ital c}){sup 2}. These measurements combined with previous data on {sup 3}He ...and {sup 3}H allow us to separate the three-nucleon isospin charge and magnetic form factors up to {ital Q}{sup 2}=1 (GeV/{ital c}){sup 2}. A large discrepancy between experiment and theory occurs for the {ital T}=1 charge form factor.
