Case Reports in Obstetrics and Gynecology , 2012, DOI: 10.1155/2012/597489
Abstract: The ultrasound evaluation of the fetal neck has a high importance as a key point of the airway and digestive tract. We report the case of a fetus diagnosed with a cervical teratoma by ultrasound, which generated a compressive effect on airway, requiring a surgical approach EXIT (ex utero intrapartum treatment) to ensure the extrauterine viability. 1. Introduction The ultrasound evaluation of the fetal neck is increasingly important, because it has a high impact on fetal adaptation to extrauterine life. The presence of masses in this location can cause obstructive problems at airway, producing complications during the course of pregnancy, as the development of polyhydramnios. But the biggest problem is after delivery, with the appearance of acute neonatal asphyxia with newborn death, if you do not carry out invasive techniques for resolution. One of these approaches is the realization of EXIT surgery, a technique designed to allow partial fetal delivery by cesarean section, with establishment of a secure airway, using intubation, bronchoscopy, or tracheostomy, while fetal oxygenation is maintained by the uteroplacental circulation. 2. Case Presentation A primigravida, 25-years-old patient, it showed a cervical tumor heterogeneous solid-liquid content of 43 × 44?mm, moderately vascularized, in ultrasound study in week 22 (Figure 1), with male fetus and normal anatomical exploration, visualizing gastric chamber. We propose to make a genetic amniocentesis, but the patient rejected it. Magnetic resonance (MR) was requested in the 25th week of gestation, describing 56 × 43 × 38?mm heterogeneous mass in anterior cervical position, with high bilateral extension, solid-cystic component, without thoracic infiltration (Figure 2). We suspect a congenital cervical teratoma by ultrasound and MR images. Figure 1: Ultrasound at 22 weeks, where heterogeneous tumor is found in cervical position, moderately vascularized. Figure 2: Nuclear magnetic resonance at 25 weeks, showing heterogeneous mass in cervical situation. New ultrasound study in 26 +5 weeks, shows a significant growth of the mass, 69 × 53?mm size (Figure 3). The patient wishes to continue the pregnancy. New MR control in week 29, shows an increase of significant size, high anterior growth, without existing intrathoracic extension. Similar proportion of solid and cystic component, with a sagittal plane measurement of 61 × 63?mm and coronal plane 51 × 93?mm, with partial compression of the air-digestive track, but an adequate fetal stomach fullness.

Participa??o arriscada: manifesta??es e tumultos em regimes ditatoriais
Escribà-Folch, Abel;
Dados , 2008, DOI: 10.1590/S0011-52582008000300006
Abstract: this article draws on a broad sample of countries to empirically test the different theories on dissent and protest in the context of authoritarian regimes, where such activities are generally repressed and are therefore risky. the empirical results of the longitudinal comparative analysis basically confirm the predictions of the rational economic approach to political protest as well as the explanatory power of structural factors, the relative deprivation theory, the political diffusion processes (at the regional level), the role of dictatorial institutions, and in part the resource mobilization theory. the empirical analysis also shows that non-violent participation is one of the main determinants of riots and that past protest is important in determining present protest (whatever its type).
Maten al león: El castigo a los dictadores salientes
Escribà-Folch, Abel;
Revista mexicana de sociología , 2008,
Abstract: this article analyzes the conditions under which dictators are punished after losing power. a new variable that codifies the fate of dictators defeated between 1946 and 2000 is used to demonstrate the inability of subsequent democratic regimes to bring former tyrants to justice for strategic reasons. it also provides evidence that punishment is more likely for personalistic dictators, and much less for military or one party regimes. at the same time, the international context has counter-intuitive effects: a higher number of dictatorships in the region make punishment more likely, whereas a higher percentage of democracies in the world makes it more difficult.

Maten al león: El castigo a los dictadores salientes Kill the Lion: Punishment for Exiting Dictators
Abel Escribà-Folch
Revista mexicana de sociología , 2008,
Abstract: Este artículo analiza las condiciones bajo las cuales los dictadores son castigados tras perder el poder. Mediante el empleo de una nueva variable que codifica cuál fue el destino de los dictadores derrocados entre 1946 y 2000 se demuestra la incapacidad de los regímenes democráticos sucesores para llevar ante la justicia a sus antiguos tiranos por razones estratégicas. Además, se ofrece evidencia de que el castigo es más probable para dictadores perso nalistas, y mucho menos para líderes de regímenes militares o de partido único. El contexto internacional tiene efectos contraintuitivos: un mayor número de dictaduras en la región hace el castigo más probable, mientras un mayor porcentaje de democracias en el mundo lo dificultan.

La determinacion de hierro en arroz. Aplicación de la espectroscopia de fluorescencia de rayos x (FRX) y espectrometría de emision atomica (ICP-AES)
Elisabet Carina Folch
Invenio , 2007,
Abstract: Los análisis por espectroscopia de fluorescencia de rayos X (FRX) y por espectrometría de emisión atómica (AES) son utilizados como procesos continuo de control de calidad y medios de investigación. Con el propósito de evaluar la aplicación de estas técnicas de análisis químico instrumental de alta performance para la determinación de la composición nutricional de productos alimenticios, se procedió a la determinación cuali y cuantitativa de hierro en distintos tipos de arroz. Por FRX se identificó la presencia de hierro, a través de las líneas espectrales correspondientes. El método desarrollado mediante la utilización de ataque ácido y posterior determinación por ICP-AES, permitió determinar adecuadamente la concentración de Fe en muestras de arroz de distintas marcas comerciales. Para el arroz grano largo, el contenido de hierro es igual a 0,413; para el grano corto, 0,358; y para el grano doble fortuna, 0,653. Los resultados obtenidos son comparables con datos provenientes de referencias bibliográficas.
Phase-field Modeling of Eutectic Solidification: From Oscillations to Invasion
R. Folch,M. Plapp
Physics , 2002,
Abstract: We develop a phase-field model of eutectic growth that uses three phase fields, admits strictly binary interfaces as stable solutions, and has a smooth free energy functional. We use this model to simulate oscillatory limit cycles in two-dimensional lamellar growth, and find a continuous evolution from low-amplitude oscillations to successive invasions of one solid phase by the other when the lamellar spacing is varied.
