3D Reconstruction with Spiral Computed Tomography in Choroidal Osteoma  [PDF]
Francisco Javier Ascaso, Laura Herrera, Laura Villén, Rafael Lasierra, Juan Iba?ez, Diana Pérez, José Angel Cristóbal
Open Journal of Ophthalmology (OJOph) , 2013, DOI: 10.4236/ojoph.2013.31002
Abstract:

Choroidal osteoma (CO) is a rare, ossifying benign tumor originated in the choroid that typically occurs in otherwise healthy young women (1,2). It is characterized by a yellowish, well demarcated lesion in the juxtapapillary or macular area. The diagnosis is clinical and can be confirmed with the use of fluorescein or indocyanine angiography, optical coherence tomography, computed tomography or magnetic resonance imaging. Choroidal neovascularization or subretinal fluid, the main causes for vision loss, can be treated with laser therapy, photodynamic therapy or intravitreal antivascular endothelial growth factor therapy. We present a case of choroidal osteoma, showing the role of the high resolution 3D spiral computed tomography.

El ukumar: lo monstruoso en el discurso evangelizador de la conquista
Angulo Villán,Florencia Raquel;
Cuadernos de la Facultad de Humanidades y Ciencias Sociales. Universidad Nacional de Jujuy , 2005,
Abstract: many communities of jujuy province still conserve an enormous oral tradition that has its origins in prehispanic ages. these oral discourses have undergone permanent versions from the conflicting intersection with the colonial cultural universe. by royal order, colonial priests and civil employees iniciated a manipulation of these texts that gave identity to the prehispanic subject and with which it was wranted to restore the new sociocultural paradigms in america. being based on aristoteles' doctrines, it was demonstrated the indian rational incapacity and was affirmed the politic of the most perfect over the most imperfect dominion. the missionaries were the ones incharge of the manipulation of the indian communities imaginary. trained in speech, they appropriated the indians discourses. they drained them of the contents that gave sense them and had governed the prehispanic world. they were loaded of new senses, opposite and often contradictory to the narive americans vision. thes work tries to observe how in the ukumar storis, the potentialities of the church discourse from the monstrous image update like image of racial degeneration can be reactivated. to approach the reading of different versions on the ukumar is an attempt of fragments reactivation of the church discourse that is summoned in these texts across the monstrous and harnessed by the description of the satanic.
Representaciones del poder y la marginalidad en la literatura del NOA
Angulo Villán,Florencia Raquel;
Cuadernos de la Facultad de Humanidades y Ciencias Sociales. Universidad Nacional de Jujuy , 2002,
Abstract: the social and cultural environment of the peripheral region of the north-west of argentina is more than a political or geographical destiny. this situation of segregation is being repeated from the prehispanic periods up to the present time. the dichotomic construction down-town / periphery is becoming a conflictive nucleus, because it has to resist the frontier lines. mignolo quoting franz fanon, points out that "he has conceptualised the boundaries as zones of colonial expansion and of violence rather than zones of contact".(*) precisely this violence against the human being, against identity, against the occidental culture and its progress, and against the andina culture and its postponement, is being emphasized in the productions of carlos aparicio and alberto alabí. the organization of power is inferred from a careful reading of their short stories -organization that coincides with the "city"- and that limits the segregating spaces. domination generates places of resistence that vary according to the narrative, but they constantly appear as a corresponding relation of that segregation between power and marginality. the generating structures of that space of social and economic separation, both in aparicio's and alabí's short stories, are produced by narrative sequencies of possession sear and reivindication, in constant tension with power.

Representaciones del Mundo Andino en un relato oral sobre fantasmas.
Florencia Raquel Angulo Villán
m@gm@ , 2010,
Abstract: Este trabajo centra el análisis en las narraciones de tradición oral que tematizan las historias de fantasmas. Si bien existen “constelaciones de imágenes” más o menos constantes compartidas por el ser humano y su entorno material y social, éstas se enriquecen en tanto pueden ser leídas desde los códigos de la cultura que las produce. En este caso, representada por la zona andina. La metodología utilizada pondrá en relación las categorías de imaginario desde una perspectiva antropológica y los aportes de la filosofía andina, sustentada en los principios de reciprocidad y complementariedad. La lectura analítica tiene como objetivo poner de manifiesto cómo los discursos orales que circulan en una comunidad en particular se constituyen como estrategias de consolidación de la “memoria” de un pueblo.

Abstract: Se uso distintas técnicas - incluyendo las pruebas de Schmidt de virutas; de Wolcott modificada; de preferencia; Standard de arena, Cajas Skaife; y de inanición - para evaluar la resistencia termítica a Porotermes quadricollis (Rambur) de distintas maderas. Como resultado de los ensayos, las maderas se ordenaron según su resistencia termítica en tres. Baja: Pino (natural) Pinus radiata D.Don, Ma ío Podocarpus saligna D.Don y Olivillo Aextoxiconpunctatum Ruiz et Pavón. Mediana: Alerce Fitzroya cupressoides (Molina), Pino Insigne aglomerado, Raulí Nothophagus alpina (Poepp. et Endl.) y Roble Nothophagus obliqua (Mirbel). Alta: Laurel Laurelia sempervirens (Ruiz et Pavón), Araucaria Araucaria araucana (Molina) y Lingue Persea tingue (Ruiz et Pavón). El Laurel demostró la mayor resistencia termítica. El Pino Insigne impregnado con Sales Boliden (K33, 6 kg x m ) demostró ser altamente tóxico para este termite. Los individuos que lo consumieron resistieron hasta 13 días, ligeramente más que los termites sometidos a la prueba de inanición; las excretas negras y el dermoesqueleto alterado, demostraron los efectos de la intoxicación. Se estimó que la capacidad de consumo de 50 termites de 0.8 - 10 mm, en 30 días es de: 0.247 g - 0.232 Pino insigne y Ma ío; 2.206 g - 0.187 g Lingue, Coigue, Raulí, Alerce, Araucaria; 0.179 g- 0.077 g Lurel, Ulmo, Olivillo. Different techniques - Schmidt's test on wood shavings; Wolcot standard test with sand; Skaife box; test of preference; and starvation test - were used to measure wood resistance to the termite Porotermes quadricollis (Rambur). Species were arranged into three groups according to their termite resistance: Low: Monterrey pine (natural) (Pinus radiata D.Don), Ma ío (Podocarpus saligna D.Don), and Olivillo Aetoxiconpunctatum Ruiz et Pavon. Middle: Alerce Fitzroya cupressoides (Molina), agglomerate Monterrey pine, Raulí Nothophagus alpina Poepp. et Endl., and Roble Nothophagus obliqua (Mirbel). High: Laurel Laurelia sempervirens (Ruiz et Pavon), Araucaria Araucaria araucana (Molina), and Lingue Persea lingue (Ruiz et Pavon). Among the untreated woods, Laurel showed the highest resistance to termite damage. Monterrey pine treated with Boliden salts (K33, 6 kg x m ) was highly toxic to termites. Individuals that fed on treated wood did not live significantly longer than termites from the starvation test. Black feces and damaged exoskeleton shows the effect of intoxication. According to the amount of wood consumed in 30 days by 50 termites, resistance to termites was:0.247 g - 0.232 Pinus Monterrey and Ma ío; 2.206 g

Abstract: the official religion suits the peregrination to río blanco town, departmen of palpalá, jujuy province, argentina, place in which it is renderet devotion to the virgin with the same name. this peregrination takes place every year during four sundays of the month of october and it summos people of different points of the province. although many people participate in the peregrination to río blanco because of thein religious devotion, for other, the celebration constitutes a tie social encounter related to spectacle and heathen entertainment. this practice is accepled in informal way by the church like atraction means to mantain the celebration. the theoretical metodologic frame follows foucault's line. it is a work done in contrast and comparison with other instances trying to look for the ruptures with a constructive attitude. it has its limit in the constradiction. it begins from seven interviews to pilgrims and people who participate in the social show. these discourses allow to look for the ramifications that generate different statements about a same theme. for this it will be taken account the emergency ambit, delineation and specificity of those ones. in conclusion, the festivity of the virgin constructs a semiotic border constituted by profane activities. the border between the sacred and profane activities allows the legitimation of all cultural spaces but fundmentally generates the reproduction and strengthening of the religious core that keeps immovable due to the presence of these other spheres.
Presencia de la lírica femenina en la revista "Jujuy" (1936-1940)

Cuadernos de la Facultad de Humanidades y Ciencias Sociales. Universidad Nacional de Jujuy , 2007,
Abstract: to trace literary production in jujuy is a difficult task, mainly because there is not a physical space in which the whole of the bibliographic production has been kept. it is also a difficult task to register women's production, above all because we can not find books by women-writers dated before the nineteen thirties. the first recorded literary piece published by a woman dates back to 1934. there exist, however, periodical publications -newspapers, magazines- that have hosted women's voices throughout time and even though the jov is exhausting it is by no means fruitless. although there are only two known pieces published by women in the decade that goes from 1934-1944 the presence of women is highlighted in "jujuy" magazine whose first issue appeared in september 1936 and last one in february 1940. our present study has the aim to explore tematic and formal characteristics present in women's lyric in the above mertioned publication which circulated in the province in the mid-thirties. as a result of this, we will attempt to settle two critical issues. in the first place, to what extent these publications form part of a literary tradition but also what propositions of rupture an renewal they exhibit. as a second major question we ar interested in disclosing what social standing women possessed in those days.

Tecnología en Marcha , 2010,
Abstract: Este trabajo de investigación se orientó a la elaboración de un sistema de cómputo bajo el título ESPADREN, software para el cálculo de espaciamiento de drenes, utilizando Visual Basic y pretende ser una herramienta que permita facilitar y simplificar los cálculos laboriosos que se deben realizar en el cálculo de espaciamiento de sistemas de drenaje. El software permite el cálculo de espaciamiento de drenes tanto para régimen permanente, utilizando las fórmulas de Donnan, Hooghoudt, Dagan y Ernst, así como para régimen no permanente, utilizando las fórmulas de Glover-Dumm y Jenab, tanto para drenes abiertos, como para tuberías enterradas. Las alternativas de cálculo se refieren a suelos homogéneos, y a suelos con dos estratos. En la investigación se probaron diferentes métodos numéricos para la solución de las ecuaciones, seleccionándose el más adecuado para cada situación. También se probaron ecuaciones de correlación simple y compuesta, lineal y no lineal, para obtener ecuaciones que se ajusten de la mejor manera a los nomogramas y tablas que se usan en el proceso tradicional del cálculo de espaciamiento de drenes. El producto del trabajo proporciona al ingeniero agrícola, civil, agrónomo y otros especialistas que trabajen en el campo del drenaje, una herramienta que permite realizar cálculos, simulaciones rápidas, y optimizar el dise o.
