La función de las imágenes en la reflexión filosófica de Cicerón
Diony González
Revista de Estudios Sociales , 2012,
Abstract: The Greek rhetorical tradition and its development during the Hellenistic period allowed rhetoric in Rome to have a broader purpose, ceasing to be the source of creation of technical manuals with function and utility for a particular forensic activity. Cicero and, subsequently, Quintilian wrote a series of handbooks, rhetorical treatises, or literary dialogues with the purpose of establishing a complete theory of the new symbolic, political and persuasive role of the orator, not only through the creation of new rhetorical theories, but also of new frameworks for philosophical thought. This is the moment when rhetorical theory conceives the word as an image, and it is only through the process of representation that one can understand and construct a discourse about reality.
Some New Questions about the Seasonal Decrease of the Ozone Layer  [PDF]
Jaime González Velasco
Green and Sustainable Chemistry (GSC) , 2012, DOI: 10.4236/gsc.2012.23016
Abstract: The depletion-recovery cycle of the ozone layer is explained on the basis of the magnetic properties of oxygen, ozone, nitrogen oxides and chlorine combinations, which upon interaction with the Earth’s magnetic field, give rise to gaseous fluxes polar- and equatorial-wards.
What Does “Noise Pollution” Mean?  [PDF]
Alice Elizabeth González
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.54037

Noise features different characteristics that make it different from every other “classic” pollutant. Noise is invisible; it does not smell; it disappears when the source is turned off and leaves no traces in the environment. In addition, when people perceive something wrong about their hearing capacity, it is often long time after the beginning of noise exposure. This fact contributes to strengthening the misconception that noise is not harmful to human health or, at least, efforts and funds aim preferably at controling and decreasing the emission of other pollutants. Adding to this, most people tend to consider that noise is the price to pay for accessing to the amenities of the Technological Era and it is indivisible and inevitably linked to them. Last but not least, noise pollution could adversely affect ecosystems and ecological services. Then, how is it possible to convince the decision makers that noise pollution is one of the major current environmental problems? The aim of this paper is to discuss step by step the applicability of noise of a “pollution” definition, as a way to ease the understanding that lowering environmental noise levels should be prioritized: because it will lead to a healthier and better society.

Some Ideas about the Thermal Equilibrium in the Biosphere and the Entropy Variation Ascribed to Changes in the Radiations Wavelengths  [PDF]
Jaime González Velasco
Open Journal of Physical Chemistry (OJPC) , 2015, DOI: 10.4236/ojpc.2015.54011
Abstract: An explanation is given for the thermal equilibrium in the biosphere, which is based in the equality between the thermal energy received from the sun and the thermal energy reemitted from the atmosphere to the space. In order to understand the origin of the energy that gives rise to the processes and phenomena taking place in the biosphere, it is necessary to take into account the free energy represented by the product of temperature times the change in entropy, T△S, whose magnitude can be attributed to the variation experimented by the wavelengths (or, consequently, the frequencies) of the radiations composing the radiation spectrum received from the sun compared with the radiation spectrum reemitted from the biosphere into the space. A simple discussion allows to predict that the entropy increase driving the processes is connected with a spontaneous conversion of high frequency radiations (with lower “content” of entropy) in radiations of lower frequencies (with higher “content” of entropy). A consequence of this is that high frequency radiations would correspond to more ordered states and, therefore, to less probable states than those corresponding to radiations of lower frequencies.
Quién custodia a los custodios de la ética?
Diony Alvarado Pinto
Espacio Abierto , 2011,
Abstract: La presente reflexión tiene como finalidad presentar un panorama general sobre el control ético ejercido por el pensamiento moderno sobre la sociedad bajo la óptica de la crítica posmoderna. Con un énfasis propedéutico, expone la paradoja que la modernidad trajo consigo al tiempo que condenaba de la fe religiosa, el culto a la razón todopoderosa. En este sentido, los custodios de la ética como guardianes de la sabiduría y del poder necesario para ejercerla, eran los indicados para imponer una moral ajena a los sentimientos de las personas; una ética codificada. De allí surge el deber para los débiles de los poderosos, quienes estaban llamados a guiar el camino a la perfección de la sociedad entera. En conclusión, la posmodernidad demostró el caos oculto en tales pretensiones, configurando una nueva realidad que se sincera con los deseos y las emociones humanas, en medio de la incertidumbre de los nuevos tiempos.
Modeling of the Water Table Level Response Due to Extraordinary Precipitation Events: The Case of the Guadalupe Valley Aquifer  [PDF]
Javier González Ramírez, Rogelio Vázquez González
International Journal of Geosciences (IJG) , 2013, DOI: 10.4236/ijg.2013.46088

A two-dimensional algorithm for underground water flow simulation was modified and adapted to the geohydrologic conditions of the Guadalupe valley located in the state of Baja California in northern México. In order to solve the numerical model using the balance equation, the central finite differences with spatial and temporal constant increments method were used. Such model considers a heterogeneous and transient unconfined aquifer. Modeling and calibration processes are presented using the data of water table levels provided by the water level data loggers installed in a monitoring network and precipitation data from climatic stations of both seasons: 2009-2010 and 2010-2011. It was possible to locate, correlate and model specific rainfall-recharge events with the aim of obtaining an estimation of how these events are directly reflected on the water table level of the aquifer and how it reacts against simulated extraordinary events.

Thermodynamic and Dynamic of Chromium Biosorption by Pectic and Lignocellulocic Biowastes  [PDF]
Luis Sala, Juan González
Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.210106
Abstract: Orange peel (OP) and rice husk (RH) were tested as low-cost biosorbents for Cr(III) removal from aqueous solutions. Dynamics of the biosorption process indicated that intraparticle mass transfer represents the rate-limiting step in the system that attained equilibrium at 120 min. While the OP sorbent material was capable of taking up 39.11 mg Cr(III)/g at the optimum pH 4.4, RH immobilized 3.20 mg Cr(III)/g at the optimum pH 3.0. The fitting of different sorption isotherms models resulted in the best fit with the Langmuir isotherm model. The mean free energy of the metal sorption process was in the range of 8-16 kJ/M. Abiotic Cr(VI) reduction was observed at various contact times and Cr-laden biomass was characterized by XPS, XAFS and EPR spectroscopy. These instrumental analyses confirmed that Cr(VI) removed from the solution was reduced and bound to the biomass as Cr(III). Results indicated that OP and RH materials are efficient biosorbents for eliminating Chromium from aqueous solutions.

Camagüey: Un modelo de estructuración territorial para servicios
González González,Rosa;
Arquitectura y Urbanismo , 2012,
Abstract: the contributions made from tourist planning are true, but reality shows that citizen experiences are not enough to success. so it is impòrtant to reverse the process, identifying the citizen′s needs to use services and analyzing tourism as an opportunity for local development through the the use of means to overcome this situation. the research makes use of different approaches: dialectic, statistical and the systemic approach. as a main conclusion, the model shows the animation proposals, the indicators for the study of city services and extra-hotelkeepers that contribute to the diagnosis of the information, based on a study of potentialities and an economic assessment.
