Generic Method for Merging Satellite and Historical Ground Station Data to Design Rainfall Intensity Duration Frequency (IDF) Curves in Recordless Sub-Saharian Countries  [PDF]
Jorge E. Matos
Open Journal of Modern Hydrology (OJMH) , 2018, DOI: 10.4236/ojmh.2018.84008
Abstract: The availability of long-term rainfall records is essential to conduct a serious frequency analysis in order to estimate the effective precipitation depth. The development of the process of elaboration of IDF (Intensity-Duration-Frequency) curves for a given location requires very precise data, at least with daily frequency, obtained through the use of rainfall records. The present study presents a method used to merge historical precipitation data with the latest data collected by satellite in order to perform graphs with IDF curves in places where rainfall records are scarce. The homogeneity of the data used is analyzed in order to guarantee its statistical utility and the frequency analysis was performed with the statistical distributions of Extreme Values Type I (Gumbel), Gamma, Pearson Type III and finally with Log-Pearson Type III, in order to verify which one of them applies better to the sites chosen for this analysis: the cities of Benguela and Lobito in the south of Angola. Daily rainfall data from the TRMM mission and historical daily data were used to derive the relationships between the maximum daily precipitation and the sub-daily precipitation values. From the observed daily data, techniques of disaggregation of the collected data were used, in order to generate a synthetic precipitation sequence with the extreme values in periods of time inferior to the daily one, with statistical properties similar to the registered data. Then IDF equations are established, with which the occasional storm depth is calculated for various return periods and various durations and, after them, the IDF curves are drawn for these two geographic stations.
Cardiomyopathy protection in Chagas Disease  [PDF]
Jorge E. Mitelman, Luisa Gimenez
World Journal of Cardiovascular Diseases (WJCD) , 2013, DOI: 10.4236/wjcd.2013.37069
Abstract: There is some published evidence suggesting micro vascular endothelial dysfunction and dysautonomia involvement in Chagas disease in association with cardiomyocyte changes favoring disease progression. The combined treatment between angiotensin converting enzyme (ACE) inhibitor drugs; Simvastatin, muscarinic antibody immunoadsorbent together with fungicidal drugs would open therapeutic possibilities in this disease.
REPTILES EN EL MONUMENTO NATURAL EL MORADO (REGION METROPOLITANA, CHILE): ABUNDANCIA RELATIVA, DISTRIBUCION ALTITUDINAL Y PREFERENCIA POR ROCAS DE DISTINTO TAMA?O
Mella,Jorge E;
Gayana (Concepción) , 2007, DOI: 10.4067/S0717-65382007000100003
Abstract: this study caracterizes the reptilian fauna at el morado natural monument in the metropolitan region of chile. the relative abundance of lizards and snakes is described relative to altitude and the size of terrain boulders. four species of lizards and two species of snakes were encountered; their observed relative abundances are: liolaemus moradoensis (40,9%), l. nigroviridis (37,7%), l. valdesianus (17,1%), l. nitidus (2,7%), tachymenis chilensis (1,2%), and philodryas chamissonis (0,4%). the altitude range of the study area is 1,850 to 2,450 masl. l. nigroviridis was found throughout this altitudinal range. l. nitidus restricted to altitudes below 1,900 masl. l. moradoensis and l. valdesianus were observed no lower than 2,150 masl. (reaching l. valdesianus the 2,459 masl., increasing its previously known altitudinal range). with regard to boulder size preference, l. valdesianus demonstrated a preference for boulders with a long axis greater than 0.9 m in size. l. moradoensis preferred boulders 0.3 to 0.6 m in size. l. nigroviridis showed a preference for boulders 0.3-1.2 m in size below 2,150 masl, but above this altitude, where its distribution is syntopic with l. valdesianus, the distribution of l. nigroviridis was restricted to boulders in the 0.3-0.6 m size range. in terms of niche use (size of rocks as a niche axis): l. nigroviridis shows a niche superimposed to l. altissimus, who have a narrow niche, while l. valdesianus have a not superimposed niche, to greater size of rocks. it is interesting the displacement of niche in l. nigroviridis, the only species studied under different contexts of syntopy. thermoregulatory factors and probably the reduction of competitive pressure could explain the patterns found.
La mitología fronteriza: Turner y la modernidad
Brenna B., Jorge E.;
Estudios fronterizos , 2011,
Abstract: modernity has been creating spaces, new boundaries and borders, as metaphysical, mythological and symbolic marks of physical and imaginary territories. modern space and its borders are metaphors, boundaries that are created, walls that rise to identify with some and categorize others. in this short paper we want to approach the problem of the transformation of the idea of border (geographical, cultural, symbolic, etc.), for a reflection on the transformations of that civilized obsession called border. the border has always been a reference in facing the identities, names, symbols, different imaginary: it is more confrontational line between two otherness. from the previous framework, we reflect on turnerian mythology, as we believe that behind the creation of the imagination of the northern border is the mythical vision of the american frontier as ideological canon that explains and confirms the presence of the white race in a border re-made in the image and likeness of the "american dream". frederick turner's reflection on the role of the frontier in american history is not only the study of the importance of progress towards the west but -even more so, is the analysis of meaning that had the american frontier as a historical process that ended in 1893, as turner said, but rather extended into the twentieth century and continues to constantly shaping the process of territorialization of the border.
La cuestión del poder neutral en Schmitt
Dotti, Jorge E.;
Kriterion: Revista de Filosofia , 2008, DOI: 10.1590/S0100-512X2008000200003
Abstract: the article tries to show the importance that constant's theory of the pouvoir neutre had on carl schmitt's interpretation of the functions of the reichspr?sident, during the twenties up to 1933. even though schmitt criticises romanticism, one of its key figures is precisely constant, the german jurist recognizes that constant elaborated the constitutional institution which faces better than any other one those critical situations, under which any constitution must defend itself with legal but excepcional powers.
Cánones filosóficos y tradiciones filosóficas: El caso de la filosofía latinoamericana
Gracia,Jorge J. E.;
An??lisis filos?3fico , 2010,
Abstract: this article discusses two topics: how the philosophical canon is established and the reasons why latin american philosophy is generally excluded both from the canon of western philosophy and the canon of world philosophy. the second topic illustrates the problems that come up in the context of the first and provides answers to them. the article argues that several theories that purport to explain the formation of the canon and the exclusion of certain philosophers from the western philosophical canon in particular, do not do justice to the situation because they ignore the role of tradition in the process. more specifically, the article shows how tradition explains why latin american philosophy tends to be absent both from the canon of western philosophy and the world canon of philosophy.
De la tragedia al malestar en la cultura: Georg Simmel y Sigmund Freud
Brenna B., Jorge E.;
Argumentos (México, D.F.) , 2009,
Abstract: the purpose of this article is to make a reflection about the diagnostics on the discomfort in the modern culture, elaborated by georg simmel and sigmund freud at the end of xixth century. the idea is to analyze the role that both thinkers assign to the effects on the interior of the individual, caused by the so called illnesses of modernity (rationality, calculation, indifference, repression of the instincts, moral, etcetera). on the other hand, we try to emphasize the originality of both thinkers and, at the same time, the parallelism of his reflections in a time and a contiguous space (vienna and berlin). both reflections sustained in an original style and a will of rupture with the scientific and cultural canons of their time. finally, what we have indicated before is taken to a conclusion in which we have postulated the necessity to reconstruct the principles and the social methods whereupon sciences-especially sociology-approach a social reality in which a subject/object exists and speaks for himself.
Effects of segmented contractions of Gaussian basis sets on Dirac-Fock energies
Jorge, F. E.;
Brazilian Journal of Physics , 1999, DOI: 10.1590/S0103-97331999000300022
Abstract: dirac-fock calculations have been performed using a segmented contraction of gaussian basis sets entirely generated from the dirac-fock hamiltonian. both dirac-fock-coulomb and dirac-fock-breit self-consistent field calculations have been performed for ar (z=18), ge (z=32), sn (z=50), xe (z=54) and hg (z=80). it is found that contractions of large exponent bases of s and p symmetry species have little effect on the total and orbital energies for light atoms (ar and ge) and a large effect for intermediate (sn and xe) and heavy (hg) atoms.

ROQUE E,JORGE;
Revista chilena de pediatría , 2010, DOI: 10.4067/S0370-41062010000100002
Abstract: introduction: septic shock (ss) is a significant cause of mortality in nicus. objective: review current knowledge on hypothalamic-pituitary-adrenal axis (hpa) and the scientific support for the use of gluco-corticoids in the use of this clinical picture. we know that the patient's ability to evolve into improvement or worsening depends upon the ability of the hpa axis to develop and sustain an adequate response to the stress provoked by ss. in some patients, due to many reasons, the prolongation of ss leads to a deficit of cortisol those results in functional acute adrenal insufficiency. cortisol levels do not respond to acth stimulation test. there is no consensus among authors as to what is a normal concentration of cortisol during stress, or even if it is correlated with death among children with ss. the american college of critical care medicine guidelines for ss in pediatrics and neonatology have made some recommendations for use of hydrocortisone.
Transferencia de políticas y construcción de lecciones para la modernización administrativa
Culebro Moreno,Jorge E;
Revista Venezolana de Gerencia , 2008,
Abstract: in recent years, the public sector has been the subject of several transformations (health, education, tourism), many of them with the purpose of improving public service delivery through the introduction of novel tools that generally come from the private sector. with the objective of better analyzing this type of reform within public administration, this article pursues a double goal: on one hand, to describe the public policy transfer model in order to understand governmental management processes; and on the other hand, to explore the main elements of the lesson-building model from the outside in order to better understand the different processes and elements in administrative reform. experiences of the mexican council for tourist promotion and the planning commission of the state of jalisco are taken as application references in terms of the normative, regulative and cognitive aspects of the institutional perspective. methodologically, the article begins with the above-mentioned experiences to illustrate the distinct learning and lesson-building mechanisms to demonstrate characteristics of the institutional dimensions under which the processes of institutional transformation and administrative reform take place.
