The Hubble Field vs Dark Energy, Part II: The Lagrange-Hamilton Equation and Some Concepts on Force, Energy and Tensors in the Hubble Field  [PDF]
Lartigue G. Juan
Journal of Modern Physics (JMP) , 2017, DOI: 10.4236/jmp.2017.813131
Abstract: In a recent article [1] the author of this Part II proposed the parameter ΓH for the acceleration expansion of the Universe, instead of dark energy, defining such parameter as ΓH=H2r(M/S2) = a constant. A question about the expansive and constant acceleration of the internal levels of the Universe could be solved by equation ((3.10) ref. [1]) of the same article: Any assumed internal distance, lower than r of (ref. [2]) implies a proportional change in the squared Hubble parameter, so maintaining the constancy of the ΓH value for every stratum of the Universe. In the present work it is proved the constancy of the Hubble force by means of its generalized coordinates. As well, an equation to relate the Lagrange and the Hamilton functions is obtained for the Hubble field. Two concepts for both Hubble’s energy and tensor are also proposed. Finally, prior misprints of Part I, ref. [1], are corrected in the Appendix.
A De Sitter-Hubble Equation, the Force in Special Relativity and Some Concepts on Symmetry  [PDF]
Juan G. Lartigue
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.96080
Abstract: Previous works [1] [2] proposed several relevant characteristics of the Hubble field such as the intensity ΓH, potential VH, force FH, Poisson equation, energy EH and a tensor (Tμν)H as well as Ricci and Hubble scalars. In this paper, it is made a proposal for two new ones: the kind of the Hubble field as well as a De Sitter-Hubble equation. Moreover, it is proposed a necessary change in the equation of force in Special Relativity. It is included a paragraph on the search for Symmetry in Physics, Chemistry and Time. Conclusions mention an eventual mirror image both the intensity of the Hubble and gravitational fields as well as the relative impossibility for a Big Crunch.
On the Concept of Information and Its Role in Nature
Juan G. Roederer
Entropy , 2003, DOI: 10.3390/e5010003
Abstract: In this article we address some fundamental questions concerning information: Can the existing laws of physics adequately deal with the most striking property of information, namely to cause specific changes in the structure and energy flows of a complex system, without the information in itself representing fields, forces or energy in any of their characteristic forms? Or is information irreducible to the laws of physics and chemistry? Are information and complexity related concepts? Does the Universe, in its evolution, constantly generate new information? Or are information and information-processing exclusive attributes of living systems, related to the very definition of life? If that were the case, what happens with the physical meanings of entropy in statistical mechanics or wave function in quantum mechanics? How many distinct classes of information and information processing do exist in the biological world? How does information appear in Darwinian evolution? Does the human brain have unique properties or capabilities in terms of information processing? In what ways does information processing bring about human self-consciousness? We shall introduce the meaning of "information" in a way that is detached from human technological systems and related algorithms and semantics, and that is not based on any mathematical formula. To accomplish this we turn to the concept of interaction as the basic departing point, and identify two fundamentally different classes, with information and information-processing appearing as the key discriminator: force-field driven interactions between elementary particles and ensembles of particles in the macroscopic physical domain, and information-based interactions between certain kinds of complex systems that form the biological domain. We shall show that in an abiotic world, information plays no role; physical interactions just happen, they are driven by energy exchange between the interacting parts and do not require any operations of information processing. Information only enters the non-living physical world when a living thing interacts with it-and when a scientist extracts information through observation and measurement. But for living organisms, information is the very essence of their existence: to maintain a long-term state of unstable thermodynamic equilibrium with its surroundings, consistently increase its organization and reproduce, an organism has to rely on information-based interactions in which form or pattern, not energy, is the controlling factor. This latter class comprises biomolecular
Gómez,Juan David;
íkala, Revista de Lenguaje y Cultura , 2011,
Abstract: this essay revisits the long acknowledged but still unresolved theory/practice schism in efl teacher education. the methodology used included the research of literature related to the subject, a comparison and contrast of representative examples of its current manifestations, and an examination of its effects on a selected group of undergraduate students. results showed a need for measures to be taken that would establish a more solid link between teacher education programs and teacher needs. it ends by suggesting alternative approaches that could begin to return basic and pragmatic content to teacher education and professional development programs.
Percepción del espacio y apropiación del territorio entre los aymara de Isluga
Aedo G,Juan Angel;
Estudios atacame?os , 2008, DOI: 10.4067/S0718-10432008000200007
Abstract: an ethnological and geographical perspective helps this paper study a few principles of spatial perception and of the social appropriation of territory, in this case the village of isluga, from where our scale of observation concentrated on the experience of different social actors. this study aims to show the implications -both practical and intellectual- of the social production of locality, through the exploration of: 1) the reconstruction of the place; 2) the ontological devices constituting the landscape; 3) the problem of the center; and 4) the social morphology. considering the different scales of territorial appropriation involved, the paper finally reflects upon the way isluga inhabitants construct their social geography.
Suelos mal drenados en Venezuela
Comerma G,Juan A;
Agronomía Tropical , 2009,
Abstract: by poorly drained soils we are including those saturated with water for important periods of the year and that show hirdromorphic features in their profile. taxono-mically, we are talking of acuic suborders of vertisols, inceptisols, entisols, ultisols, alfisols and organic soils or histosols. they mainly occur in flat alluvial plains subjected to flooding and in a lesser proportion to high water tables. according to the best estimates, they occupy around 20% of the nation or 18.2 million hectares. the dominant use is extensive grazing, rice and reserves of flora and fauna. the main areas in the country are: continental deltaic plains, plains of apure state, orinoco delta, southern plains of maracaibo lake, and caribbean coastal plains. a discussion of each area includes its main characteristics, extension, origin, pedogenesis, taxonomy and present and potential land use.
Arellano G,Juan Carlos;
Atenea (Concepción) , 2009, DOI: 10.4067/S0718-04622009000100010
Abstract: the objective of this investigation is to analyze the political behavior of the chilean national party and its impact in political conflict during the period lasting from 1966 to 1973. our hypothesis is that the national party was characterized above all by a strong pragmatic attitude. the seven year existence of the party can be classified in different stages: the first stage, with the christian democratic government serving as opposition party, was characterized by electoral recovery. the second stage was primarily marked by the party,s refusal to ratify salvador allende as president of the republic. the next stages occurred within the period of allende,s unidad popular government and can be subdivided into a deslegitimization-phase, a destabilization-phase, and finally the definite break with the government.
La invención del mito de Diego Portales: La muerte y el rito fúnebre en la tradición republicana chilena
Arellano G,Juan Carlos;
Atenea (Concepción) , 2011, DOI: 10.4067/S0718-04622011000100008
Abstract: diego portales has become a true legend of chilean political history, a controversial figure who has prompted very different kinds of interpretation. the aim of this article is to analyze the origin of his political myth. we will study the final phase of the minister’s political activities in 1837 from the perspective of machiavelli’s the prince. by means of the florentine philosopher’s modern political theory, we may explain the circumstances which surrounded the death of portales. a look at portales’s funeral reveals that it responded to a need to create a republican tradition at the time of the birth of the hispano-american nations.
El positivismo excluyente de Raz
Boletín mexicano de derecho comparado , 2004,
Abstract: there have always been different interpretations regarding positivism's main tenets. as the author of this essay explains, legal positivism is not a homogenous stream, and it is of little use to support or criticize positivism in general, without pointing out the specific thesis subject to defence or scrutiny (this is valid in relation to other isms in legal philosophy). today, positivism shows this difference in points of view with an internal debate between exclusive and inclusive positivists. this article has as its main goal to explain raz' arguments concerning exclusive positivism, in order to make a contribution to the understanding of the line of argumentation that leads to this conception. in this way, the essay helps us to understand the differences between raz' perspective and other positivisms.
Derecho y narración: el carácter triplemente mimético de la juridicidad
Posada G,Juan Pablo;
Co-herencia , 2010,
Abstract: following the theory of the triple mimesis, presented by paul ricoeur in time and narration, it is possible to detect the intimate nexus that the law and the human activity of narrating maintain. mimesis i, as conceptual network and anchorage of the narrative plot, is given in the law by the law itself as a way to prescribe legally desirable actions. mimesis ii is the narration of some actions with legal relevance, narration which is carried out in the interior of the judicial process. finally, mimesis iii consists of the application of the legal hypothesis to the actions that summarize it and this by means of the sentence device as regulatory comprehension and as a mean to apply a sanction.
