TTVs analysis in Southern Stars: the case of WASP-28
Romina Petrucci,Emiliano Jofré,Mario Melita,Mercedes Gómez,Pablo Mauas
Physics , 2014, DOI: 10.1093/mnras/stu2152
Abstract: We present 4 new transit observations of the exoplanet WASP-28b observed between August 2011 and October 2013. Employing another 11 transits available in the literature we compute new ephemeris and redetermine the physical parameters of the star and the exoplanet. Considering 3 yrs of observations, we find no periodic TTVs or long-term variations of the inclination of the orbit, i, or the depth of the transit, k, that could be attributable to the presence of another planetary mass-body in the system. We also study the relations between i and k with different factors that characterize the light-curves. The fits suggest a possible weak correlation between k with the red noise factor, \beta, and the photometric noise rate, PNR, and a weak anticorrelation between i and PNR, although more points are needed to confirm these trends. Finally, the kinematic study suggests that WASP-28 is a thin disk star.
Possible chromospheric activity cycles in AD Leo
Andrea P. Buccino,Romina Petrucci,Emiliano Jofré,Pablo J. D. Mauas
Physics , 2013, DOI: 10.1088/2041-8205/781/1/L9
Abstract: AD Leo (GJ 388) is an active dM3 flare star extensively observed both in the quiescent and flaring states. Since this active star is near the fully-convective boundary, to study in detail its long-term chromospheric activity could be an appreciable contribution for the dynamo theory. Here, we analyze with the Lomb-Scargle periodogram the Ca II K line-core fluxes derived from CASLEO spectra obtained between 2001 and 2013 and the V magnitude from the ASAS database between 2004 and 2010. From both totally independent time-series, we obtain a possible activity cycle of period $\sim7$ years and a less-significant shorter one of $\sim2$ years. A tentative interpretation is that a dynamo operating near the surface could be generating the longer cycle, while a second dynamo operating in the deep convection zone could be responsible for the shorter one. Based on the long duration of our observing program at CASLEO and the fact that we observe simultaneously different spectral features, we also analyze the relation between simultaneous measurements of the Na I index ($R^{\prime}_D$), H$\alpha$ and Ca II K fluxes at different activity levels of AD Leo, including flares.

Brief communication "The assessment of damage caused by historical landslide events"
O. Petrucci
Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2013, DOI: 10.5194/nhess-13-755-2013
Abstract: The paper presents a methodology for relative damage assessment for historical landslide events, i.e. periods during which damage caused by rainfall-triggered landslides affected wide areas. The approach requires a minimum amount of data, and it is based on the assessment of direct, indirect and intangible damage indices at municipal and regional scale. An application to major events which occurred in Calabria (Italy) highlighted roads as the most vulnerable element, even representing the source of intangible damage for people forced to use alternative roads for their daily activities. Indirect costs seem mainly tied to displacement of people even for short periods.

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine , 2012, DOI: 10.1186/1757-7241-20-43
Abstract: This observational retrospective study evaluated the prevalence and drug treatment of pain in the five weeks following the L'Aquila earthquake (April 6, 2009).958 triage documents were analysed for patients pain severity, pain type, and treatment efficacy.A third of pain patients reported pain with a prevalence of 34.6%. More than half of pain patients reported severe pain (58.8%). Analgesic agents were limited to available drugs: anti-inflammatory agents, paracetamol, and weak opioids. Reduction in verbal numerical pain scores within the first 24 hours after treatment was achieved with the medications at hand. Pain prevalence and characterization exhibited a biphasic pattern with acute pain syndromes owing to trauma occurring in the first 15 days after the earthquake; traumatic pain then decreased and re-surged at around week five, owing to rebuilding efforts. In the second through fourth week, reports of pain occurred mainly owing to relapses of chronic conditions.This study indicates that pain is prevalent during natural disasters, may exhibit a discernible pattern over the weeks following the event, and current drug treatments in this region may be adequate for emergency situations.
Generalized Lagrange Structure of Deformed Minkowski Spacetime  [PDF]
Roberto Mignani, Fabio Cardone, Andrea Petrucci
Natural Science (NS) , 2014, DOI: 10.4236/ns.2014.66040
Abstract:

We discuss the generalized Lagrange structure of a deformed Minkowski space (DMS), \"\", namely a (four-dimensional) generalization of the (local) space-time based on an energy-dependent “deformation” of the usual Minkowski geometry. In \"\", local Lorentz invariance is naturally violated, due to the energy dependence of the deformed metric. Moreover, the generalized Lagrange structure of \"\" allows one to endow the deformed space-time with both curvature and torsion.


Simulacros: arte, subjetividad y resistencia
Sacchi,Emiliano;
Discusiones Filosóficas , 2010,
Abstract: in this paper i intend to show how it is possible starting with a rupture with the platonic model of thought to give rise to a consideration of aesthetics and subjectivity as fields of politic experimentation. such field of experimentation can be considered in the very core of platonic work, out of the dispute that this maintains with the artist and that leads him to expel them from the polis. in this expulsion of pretense plato intends to secure the good order of the city, to enclose art within the limits of mimesis and representation. this paper suggests to think about art and politics beyond representation because only overcoming plato's condemnation, art opens the field of resistance by which it introduces what is not presentable: the new.
Ecólogos y mega-minería, reflexiones sobre por qué y cómo involucrarse en el conflicto minero-ambiental
Donadio,Emiliano;
Ecolog?-a austral , 2009,
Abstract: the number of large scale mining operations has been increasing greatly in argentina during the last decade. because large scale mining demands the surrender of large natural areas and the extensive use of toxic substances (e.g., cyanide), it has resulted in social and environmental conflicts of diverse magnitude. an array of different social subjects has publicly stated their support or opposition to mining activities. conversely, professional societies (i.e., asociación argentina de ecología [asae] and sociedad argentina para el estudio de los mamíferos [sarem]) with active participation of ecologists have been absent from the debate. here i argue that both asae and sarem should become publicly involved the mining-environmental conflict not only to fulfill their foundational objectives (contributing to the protection and conservation of argentina's natural heritage) but also because of the scientific-technical character assumed by the documents developed and presented by mining companies (e.g., environmental impact assessments [eia], monitoring plans and reports). potential mechanisms for involvement include: active participation in the evaluation of documents produced by mining companies, public dissemination of these evaluations, collaboration with state agents responsible for evaluating eias and monitoring programs, planning and implementation of legal action against those professionals and public officers who endorse low quality technical documents, and promotion of ethical behavior within the field of ecology.
Racionalización y comunización en la esfera económica. Los matices del individualismo en la teoría de la modernidad weberiana
Emiliano Torterola
Papeles del CEIC , 2010,
Abstract: La lectura de textos clave de la teoría de la modernidad en Weber –como La ética protestante y el espíritu del capitalismo e Historia económica general- podría llevarnos a afirmar que la racionalización de la esfera económica conduce a una constante impersonalización y formalización de las relaciones societales. Sin embargo, tal teoría presenta ciertos matices, tanto desde una perspectiva histórico-cultural como a la luz de algunas categorías sociológicas weberianas. El presente artículo, tiene por objeto complejizar las interpretaciones más usuales de la teoría sociológica de comienzos del siglo XX –incluyendo la de Weber- en torno a la formación del individualismo económico moderno como epicentro del pasaje de los cálidos lazos comunitarios a los instrumentalizados vínculos asociativos. / By reading Weber’s main texts about the theory of modernity – such as The Protestant Ethic and the Spirit of Capitalism and General Economic History- the con-clusion could be reached that the rationalization of the economic sphere leads to an ongoing depersonal-ization and to the formalization of societal relationships. However, his theory does have certain shades to it, both from a historical-cultural perspective as under the light of some main Weberian sociological categories. The aim of this article is to discuss the complexities concealed by the most usual interpretations of the sociological theory at the beginnings of the 20th Cen-tury –including that of Weber– concerning the development of the modern economic individual as epicenter of the passage from the warm communal bonds to the instrumental associative relationships.
