Episode 35: Alexis Castellanos, Author of “Isla to Island”, and Her Panel Presentation during the Operación Pedro Pan Two-Day Event
No full textIn Part 1 of “Operación Pedro Pan: The Voices and Stories of Cuba’s Child Exodus—A Knights HistoryCast Mini-Series,” the Department of History’s Sebastian Garcia talked with Alexis Castellanos, an author, illustrator, graphic novelist, and a panelist at the esteemed, conspicuous, and powerful “Operación Pedro Pan: Honoring the Cultural, Historical Legacy of Cuba’s Child Exodus” Two-Day Program that Florida Humanities, UCF’s Department of English and Department of Modern Languages and Literatures sponsored (see https://cah.ucf.edu/pedro-pan/ for more details on sponsors and the program in general).
Sebastian structured this specific episode on Alexis Castellanos’ Isla to Island, a wordless graphic novel grounded by her personal family history and the history of Operación Pedro Pan (Operation Peter Pan). By analyzing such a historic event through the medium of fiction, Sebastian argued that this is one of the most unique Knights HistoryCast episodes of all time. Naturally, their conversation expanded to what she talked about during her panel presentation in Panel One, Day 1 of the event that featured “internationally renowned scholars that discussed the political, historical, and cultural legacy of Operación Pedro Pan (1960-1962).” (https://cah.ucf.edu/pedro-pan/)

THE MYSTIC ROAD : SELECTED POEMS - ALEXIS KARPOUZOS
No full text
Alexis karpouzos (born on April 09, 1967) is a philosopher, author, spiritual master and pioneer of higher consciousness. He is author of several books on philosophy, metaphysics, spirituality, modern science. His most famous books are: ‘’Universal consciousness’’, ‘’non-duality’’, ‘’An ocean of souls’’, ‘’Beyond the heaven’’. Alexis Karpouzos is also a recording artist. He has recorded two music albums and twenty-four singles songs. He has also appeared in two documentary films, television and radio productions. He is the pioneer of the post-ontology consciousness and the wisdom of universal wholeness. The global language of poetry of Alexis Karpouzos, by following the paths of wisdom, is a vehicle for transmitting human knowledge and values, history, ancient traditions, and links with nature. It transmits the human values and worldly knowledge that are essential for opening ourselves to the Other. Poetic creation, therefore, forges very strong links between humans -it transcends beyond languages, beliefs and cultures. Each poem appears in its original form, in a vibrant celebration of life, diversity, language, and the enduring power of poetry. At a time when the Humanities are under threat, this book offers a defense of poetry within the context of growing interest in mindfulness in spirituality, in consciousness, in art, in education.</p
A Scaling Relation Between the Moment Release due to Aseismic Motion and the Injected Volume of Fluid
No full textConstraining the moment release of injection-induced earthquakes is of paramount importance to reduce the seismic hazard in the geo-energy industry. Recent studies suggest that a significant part of the moment release during fluid injections can be due to aseismic motion, namely, aseismic moment M0. Current models of injection-induced aseismic moment do not incorporate fault rupture mechanics. Here, we present a theoretical and numerical analysis that highlights a possible scaling relation between the aseismic moment and a key operational parameter, the injected volume of fluid V. The scaling relation emerges from the model of a stable frictional shear crack that propagates in mixed mode (II+III) on a planar fault interface. The interface is characterized by a constant hydraulic transmissivity and a shear strength that is equal to the product of a constant friction coefficient and the local effective normal stress. Fluid is injected right into the fault interface at a constant flow rate. The resulting relation between the aseismic moment and the injected volume is M0=A⋅ V^(3/2). The prefactor A accounts for the dependence of the aseismic moment on the pre-injection stress state, the parameters of the injection (notably, the injection flow rate), and the fault elasto-frictional and hydraulic properties. Unlike previous studies, our model accounts for the possibility that ruptures can propagate beyond the fluid-pressurized fault patch, a condition that is expected to occur in critically stressed and/or highly-pressurized fractures/faults. We test the scaling relation against estimates of moment release due to aseismic motion during fluid injections that vary in size from laboratory experiments to industrial applications. Our predictions are in good agreement with these observations. These results provide a simple means to quantify the size of aseismic ruptures in response to fluid injections related to both natural and human sources.GE
Extraction of fluids to mitigate the seismic risk associated with post-injection aseismic slip
No full textSubsurface fluid injections are commonly accompanied by seismicity which can sometimes result in earthquakes of relatively large magnitude that pose a serious hazard for the geo-energy industry. Current efforts to manage the seismic risk associated with fluid injections work generally under the tacit assumption that mitigation measures will become shortly effective in preventing the occurrence of earthquakes of larger magnitude than some pre-defined threshold. A common operational measure is shutting in the wells indefinitely. Unfortunately, seismicity after shut-in is common and, even more, it is not rare that the largest events of injection-induced seismic sequences occur during the post-injection stage. Understanding the physical mechanisms underpinning post-injection seismicity is thus of first importance for the successful development of geo-energy projects. Moreover, gaining knowledge in this matter may ultimately help to design physics-based strategies to mitigate the seismic risk associated with fluid injection operations. From a pure hydro-mechanical perspective, there are two well-known triggering mechanisms for post-injection-induced seismicity, namely, the diffusion of pore-fluid pressure (Parotidis et al., 2004) and poroelastic stressing (Segall and Lu, 2015). Recently, Sáez and Lecampion (2023) have investigated a third mechanism where injection-induced aseismic slip in pre-existing fractures and faults may keep propagating after shut-in and continue stressing even larger and more distant regions from the injector during time scales that could span even months for fluid injections of only few days, if the reactivated fracture/fault is critically stressed. This result has motivated us to develop a physics-based strategy to mitigate the seismic risk associated with post-injection aseismic slip. The idea is to extract fluids as an operational measure instead of just stopping the injection. It is shown that fluid withdrawal has not only the effect of reducing the further increase of pore pressure during the post-injection stage, but also the effect of decreasing both the spatial extent and exposure time of the surrounding rock mass to quasi-static changes of stresses due to aseismic slip. The main parameter controlling the reduction of the spatial extent and exposure time is the ratio between the extraction rate and injection rate. We make use of realistic field configurations to provide examples that show the significant reduction of the exposure time that can be achieved by extracting fluids. We also discuss some field evidence that support the plausibility of this extraction strategy.GE
The effect of in-situ linear stress gradient on the frictional shear rupture growth in 2D
No full textDeep heat mining requires activation of slip on pre-existing geological discontinuities and the creation of hydraulically conductive fracture networks. Fluid injection or diffusion of ground waters can rise the fluid pressure near pre-existing fractures and faults, which may induce frictional slip. The fracturing process depends strongly on the initial stress conditions and rupture planes orientation. It is known that vertical stress is varying linearly with depth whereas horizontal stresses are likely not to exhibit linear dependence. Nevertheless, within certain length scales, one may assume linear relations for all stress tensor components. In the previous study [1], it was shown that for a planar rupture which is propagating due to fluid injection under a constant overpressure in the absence of stress gradient, the solution is self-similar and depends only on one dimensionless parameter which determines two limiting regimes. The first so-called "critically-stressed limit” designates that the fault is initially close to failure, whereas the “marginally pressurized limit” represents the case when the fluid pressure is “just sufficient” to activate the fault. One of the main features of the solution in the uniform stress case is that the rupture tips are propagating symmetrically. In our work, we investigate how linear stress gradient acting initially on the fault affects the shear rupture growth, namely, how it breaks the symmetry of the rupture propagation. The problem couples quasi-static elastic equilibrium and fluid flow on the fault plane via a Coulomb shear failure criterion with a constant friction coefficient. From a scaling analysis, it is shown that the problem is governed by two dimensionless parameters, To (similar to the one found in [1]) and dimensionless time. Parameter To is the ratio between the initial distance to failure and the strength of injection [1] calculated at the injection point. To determines two propagation regimes similar to those found in [1] (critically stressed and marginally pressurized limits). Dimensionless time parameter determines symmetric and asymmetric propagation periods and encapsulates the information about stress-gradient values. At early times, the solution is similar to the homogeneous stress case and the rupture stays symmetrical. At times near the characteristic time of each regime, the non-uniform in-situ stress distribution makes the rupture to propagate asymmetrically. We investigate the transition time for each limiting regime and compare it with real field observations. Our solution can also provide a benchmark for numerical solvers.GE

COSMOLOGY, PHILOSOPHY AND PHYSICS: ALEXIS KARPOUZOS
No full textIf physics leads us today to a world view which is essentially holistic, it returns, in a way, to its beginning, 2,500 years ago. It is interesting to follow the evolution of Western science along its spiral path, starting from the mystical philosophies of the early Greeks, rising and unfolding in an impressive development of intellectual thought that increasingly turned away from its mystical origins to develop a world view which is in sharp contrast to that of the Far East In its most recent stages, Western science is finally overcoming this view and coming back to those of the early Greek and the Eastern philosophies. This time, however, it is not only based on intuition, but also on experiments of great precision and sophistication, and on a rigorous and consistent mathematical formalism. The parallels to modem physics appear not only in the Vedas of Hinduism, in the I Ching , or in the Buddhist sutras, but also in the fragments of Heraclitus, Parmenides, Plotinus, African-American philosophy, the eastern negative theology, in the Sufism of lbn Arabi, in the holistic spirit of Giordano Bruno and Meister Eckhart, in monadology of Leibniz, in the Absolute Idea of Hegel and Shelling, e.t.
All ancient spiritual traditions suggest that the world is a unity and the multiplicity is only apparent. Modern science claims that the visible world of matter and the multiplicity is only apparent, the reality is unseen and invisible. Since different roads the mysticism and the rationalism lead to the same view, the view of the open totality of the world. The mystical insight of spirituality and the rational mind of science leading to the open thought, the wisdom of life. The spiritual experience of oneness conduces to the same insight as reasoning through science. Both convey the insight of fundamental interconnection between ourselves, other people, other forms of life, the biosphere and, ultimately, the universe. Science and spirituality, far from being mutually exclusive and conflicting elements, are complementary partners in the search for the path that can enable humanity to recover its oneness with the world. Science demonstrates the urgent and objective need for it; and spirituality testifies to its inherent value and supreme desirability. We can reason to our oneness in the world, and we can experience our oneness with the world. The time has come to do both, for they are complementary and mutually reinforcing.
Presents a revolutionary new paradigm of Cosmic Thought that bridges the divide between science and spirituality. Discloses the ramifications of non-localized consciousness and how the physical world and spiritual experience are two aspects of the same Cosmos. What scientists are now finding at the outermost frontiers of every field is overturning all the basic premises concerning the nature of matter and reality.The essays on this book are the notes from the international e – learning courses that were given by the philosopher, and author Alexis Karpouzos during the winter of 2014. Students studying in London, Amsterdam, Berlin and Paris took part in the courses, which were held by the educational and cultural center "Alexis karpouzos community", located in Athens
