"Andanzas crepusculares" de Luis Franco : un ensayo de bucólicas con detalles virgilianos

"Andanzas crepusculares" es una parte del libro La flauta de caña, primer poemario de Luis Franco, publicado en 1920. La mayoría de los poemas de este libro cuentan con numerosos elementos bucólicos clásicos, pero el conjunto de composiciones reunidas bajo el título común de "Andanzas crepusculares" comparte unidad en diversos aspectos que la singulariza respecto de las demás composiciones. En ese grupo de composiciones subyace la posibilidad de un proyecto individual que finalmente quedó como una parte del libro que integra. Analizamos casos relevantes de recepción, intertextualidad y reescritura, que permiten vincular el conjunto "Andanzas crepusculares" con las Églogas de Virgilio

Etapas de la recepción clásica en la obra de Luis Franco

En este trabajo describimos sintéticamente las etapas en que puede ser dividida la obra de Luis Franco a partir de la presencia y la función de las culturas griega y romana en algunos de sus principales libros. A través de ejemplos, señalamos las características más notables de recepción de la cultura clásica, algunos procesos de selección y modos de apropiación del mundo clásico que Luis Franco practicó desde una perspectiva deliberadamente no académica sino autodidacta y personalIn this paper we briefly describe the stages in which Luis Franco's work may be divided from the presence and function of Greek and Roman culture in some of his books. By means of examples, the most outstanding characteristics of classical culture reception will be pointed out, as well as some processes of selection and appropriation of the classical world that Luis Franco carried out from a deliberately non-academic, autodidactic and personal perspectiv

The Unsuspected Intrinsic Property of Melanin to Transform Light into Chemical Energy and the Seed Growth

Seeds are very important part of the world’s diet, contributing to half of the global per capita energy intake. Thereby, their study has a substantive relevance, reflected by numerous yearly publications. However, mysteries remain about the main molecular mechanisms involved in germination and dormancy. Seed is a completely independent living thing, and in suitable conditions, hatches and generates a new adult plant completely, identical to which they gave rise. And to do so requires only light and water in certain proportions. Theoretically, the seed has reserves of nutrients that allow it to grow, until their so‐called autotrophic features allow them to establish itself as a self‐sufficient organism. So far, the above cannot be explained adequately, we only have abundant theories that come and go. However, our finding of the intrinsic property of melanin is that it transforms the visible and invisible light to chemical energy through the water molecule dissociation and marks a before and an after process in the study of the germination of the seeds. Nutrients that can be found in a seed not only provide energy but also elements to be biomass, that is, mainly carbon chains of different lengths and combinations, which eventually constitute the backbone of more than 95% of biomolecules. The chemical energy that the seed requires to carry out the highly complex chemical reactions necessary for hatching is taken from water, dissociating it through melanin

Perturbations in Generation and Flow of Energy in the Eukaryotic Cell Explain the Chromosomal Instability Syndrome

Chromosomal instability is poorly defined and used inconsistently and imprecisely. It is the increased propensity to chromosome aberrations due to chromosome replication, repair, or segregation. Therefore, acquired genetic changes are central to leukemia development. Fast-growing cells require substantive amount of energy; however, tumor cells take up more glucose, processing it through aerobic glycolysis producing large lactate amounts with lower use of oxidative phosphorylation to generate ATP. The Warburg effect is characterized by reduced use of tricarboxylic acid cycle, so pyruvate made in glycolysis is converted into lactate and expelled, but this metabolic pathway is energetically inefficient. When genes are malfunctioning, both oncogenes and tumor suppressor genes influence negatively the switch between aerobic glycolysis and extensive use of TCA cycle to generate ATP, as the normal gene replication and expression require adequate energy levels. Chromosomal instability is increasingly entangled and unnecessarily complex. So far, researchers focused solely on studying the mass and have forgotten the energy. The intrinsic property of melanin to transform light into chemical energy, through water dissociation, as chlorophyll in plants, opens a new landscape in chromosome biology, highlighting the role of the environment toxics in leukemia pathogenesis, inhalation being the dominant pathway of exposure

The Energy as a Determinant Factor in the Ethiopathogeny of Chromosomal Abnormalities. The Unsuspected Bioenergetic Role of Melanin

In the study of chromosomal abnormalities, in genetics, and in medicine in general, attention is rarely paid to the role of energy in the healthy subject and in the sick patient. The research on the chromosomal anomalies that are constantly published, does not mention the energy necessary for the biochemical processes involved in the function, replication and formation of genes, to be carried out in an adequate way. It seems that it is assumed that energy levels are always fine or at least did not have a significant role in the conditions associated with what we call chromosomal anomalies. A characteristic of the cell nucleus that has gone unnoticed is that it contains neither mitochondria nor ATP, much less glucose. Perhaps because of this, some researchers and clinicians come to think that the nucleus of cells does not require energy. The purpose of this work is to draw attention to the importance of energy levels in all the metabolic processes of the cell; and to make known that glucose is not an energy source, as it is only a source of carbon chains; and finally remark that our body, through melanin, can take energy directly from light

¿Por qué el estudio del lenguaje es fundamental para la cognición?

El estudio del lenguaje tiene un campo específico que, durante mucho tiempo, antes de la segunda mitad del siglo XX no había presentado mayor interés en relación a la cognición. Desde que se piensa al hombre como el único ser con la capacidad para hacer uso de la lengua, se han realizado descubrimientos de variada índole sobre lo específicamente lingüístico, de igual manera surge (a-posteriori) interés por el estudio de la cognición de forma paralela para complementar investigaciones respecto al lenguaje. En este artículo se presenta un análisis casi preciso sobre la incidencia del lenguaje en la cognición y, la implicación de ambos en la educación. Sobre el lenguaje hay muchas investigaciones como de la cognición, pero se han tratado por separado antes del siglo mencionado; en la actualidad diversos estudios confirman que ambos elementos no pueden tratarse por separado porque conforman parte de un todo, del cerebro. En éste hay procesos específicos, actividad que se muestra desde el contenido lingüístico para el procesamiento de la información. Concretamente se estudia el lenguaje como elemento constitutivo de la cognición para afianzar el conocimiento, esto sólo puede evidenciarse desde lo práctico, en el desarrollo evolutivo del ser humano. En este artículo los aportes de la neurociencia no pasan desapercibidos, antes bien se toman como recurso argumentativo para fortalecer las reflexiones que se irán desarrollando y es que los resultados de recientes investigaciones hacen posible develar pocos de los muchos misterios que esconde el cerebro afines al procesamiento de la información; enfatizando ‘el cómo se conoce’, se almacenan datos, y pueden volver a ser utilizados. ¿Acaso se conoce porque se puede acceder a mayor cantidad de información a través de los sentidos o porque se sabe dar razón de la información sensorial que se posee y se ha almacenado discriminadamente en el cerebro? // The study of language has a specific field for a long time, before the second half of the twentieth century had not made greater interest in relation to cognition. Since it is thought the man as the only being with the ability to use language, there have been discoveries of various kinds about what specifically linguistic, likewise arises (a-posteriori) interest in the study of cognition so parallel investigations to complement the language. In this paper an almost precise analysis on the impact of language in cognition and involvement both in education is presented. About language therebare many investigations and cognition, but have been treated separately before mentioned century; now several studies confirm that both elements can not be treated separately because they form part of a whole brain. In this there are specific processes, activity displayed from the linguistic content for information processing. Specifically, the language is studied as a constitutive element of cognition to strengthen knowledge, this may only become evident from the practical, in the evolutionary development of the human being. In this paper the contributions of neuroscience do not go unnoticed, rather taken as argumentative resource to strengthen the reflections that will be developed and the results of recent research make it possible to reveal a few of the many mysteries that hides the related brain processing of the information; emphasizing ‘how is called’ data is stored and can be reused. Did you know that you can access as much information through the senses or because it is known to account for sensory information held and discriminately has been stored in the brain

Gravitational lensing by wave dark matter halos

Wave Dark Matter (WaveDM) has recently gained attention as a viable candidate to account for the dark matter content of the Universe. In this paper we explore the extent to which dark matter halos in this model, and under what conditions, are able to reproduce strong lensing systems. First, we analytically explore the lensing properties of the model -- finding that a pure WaveDM density profile, a soliton profile, produces a weaker lensing effect than other similar cored profiles. Then we analyze models with a soliton embedded in an NFW profile, as has been found in numerical simulations of structure formation. We use a benchmark model with a boson mass of $m_a=10^{-22}{\rm eV}$, for which we see that there is a bi-modality in the contribution of the external NFW part of the profile, and actually some of the free parameters associated with it are not well constrained. We find that for configurations with boson masses $10^{-23}$ -- $10^{-22}{\rm eV}$, a range of masses preferred by dwarf galaxy kinematics, the soliton profile alone can fit the data but its size is incompatible with the luminous extent of the lens galaxies. Likewise, boson masses of the order of $10^{-21}{\rm eV}$, which would be consistent with Lyman-$\alpha$ constraints and consist of more compact soliton configurations, necessarily require the NFW part in order to reproduce the observed Einstein radii. We then conclude that lens systems impose a conservative lower bound $m_a > 10^{-24}$ and that the NFW envelope around the soliton must be present to satisfy the observational requirements.Comment: 26 pages, 7 figures, Publishe
