Secchi, Myrian Marajó Dal,Indolfo, Maria Lucia Pozzobon,Rabesquine, Matheus Moro,Castro, Fabrício Barbosa de
International Archives of Otorhinolaryngology , 2009,
Abstract: Introduction: The epistaxis is one the most frequent otorhinolaryngologic emergencies in the medical practice. It is a benign affection, but the refractory cases require hospital admission. Objective: To evaluate prevailing factors in patients with epistaxis and treatment. Form of study: Retrospective study. Method: 60 patients with diagnosis of epistaxis were evaluated and they needed hospital admission between 2005 and 2006. Results: The main prevailing factors were: Systemic arterial hypertension 36% (n= 22), trauma 16% (n=10) and coagulopathy 5% (n=3). The treatment was the use of nasal splint: anterior 58% (n=35) and antero-posterior 27% (n=16), the electrocauterization of the identified bloody point 7% (n=4), endoscopic arterial bandage 8% (n=5) in severe epistaxis. For the patients with antero-posterior splint with recurrence of bleeding in the first 24 hours (five patients), after clinical stabilization, an arterial bandage was indicated by endoscopic means; four patients had systemic arterial hypertension and in one patient no prevailing factor was identified. Conclusion: The main associated prevailing factors were systemic arterial hypertension, trauma and coagulopathy. The treatment depends on the type, severity and cause of bleeding, initially the anterior and antero-posterior splint for bleeding control. The early endoscopic arterial bandage is indicated in patients with severe epistaxis and prevailing factors, and prolonged admission and morbidities associated with nasal splint should be avoided.

Os pacientes com tamponamento antero-posterior com recorrência do sangramento nas primeiras 24 horas (cinco pacientes), após estabiliza o clínica, foi indicada a ligadura arterial por via endoscópica, sendo que quatro pacientes apresentavam hipertens o arterial sistêmica e um paciente n o foi identificado fator predisponente. Conclus o: Os principais fatores predisponentes associados foram hipertens o arterial sistêmica, trauma e coagulopatias. O tratamento depende do tipo, severidade e causa do sangramento, inicialmente o tamponamento anterior ou antero-posterior para controle do sangramento. A ligadura arterial endoscópica precoce está indicada em pacientes com epistaxe severa e fatores predisponentes, evitando interna es prolongadas e morbidades associadas com o tamponamento nasal.
Libertad de elección escolar, mecanismos de atribución de plazas y preferencias familiares: una evaluación a partir de criterios de equidad
Myrian Andrada
PROFESORADO , 2008,
Abstract: El artículo propone un esquema de evaluación de los efectos de la elección escolar sobre la equidad. Determina un conjunto de criterios derivados de las teorías de la justicia aplicadas a la educación y los articula con indicadores de equidad definidos a partir de una revisión de la literatura internacional. A partir de dicho esquema se analizan los efectos de diferentes mecanismos de atribución de plazas que permiten a las familias escoger centro escolar a partir de un tratamiento colectivo de sus preferencias. El artículo muestra que estos mecanismos no están condenados a socavar la igualdad de oportunidades educativas o a favorecer a las clases sociales más favorecidas. Sin embargo, los componentes de la formula de elección de centro y particularmente, ciertas condiciones del mecanismo de asignación de plazas son necesarias para que un dispositivo de este tipo pueda limitar de manera significativa, y a más largo plazo, disminuir los efectos negativos sobre la equidad.
Métodos ópticos Como Herramienta Para Encriptar-Desecriptar Información
Myrian Tebaldi
Bistua : Revista de la Facultad de Ciencias Básicas , 2008,
Abstract: Los datos trasmitidos a través de los sistemas informáticos son factibles de ser falsificados. No obstante es posible implementar procesos de codificación para protegerlos. La idea central radica en el uso de claves ó llaves sin las cuales es imposible recuperar la información. Las técnicas ópticas evidencian un gran potencial para el desarrollo de tales sistemas empleando la correlación óptica. Uno de los métodos más conocidos de encriptación esta basado en el uso de una doble máscara aleatoria de fase, una en el plano de entrada y la segunda en el plano de Fourier. Asimismo, se han desarrollado otros arreglos de encriptación usando usando arquitecturas de correlador JTC y técnicas de holografía digital. La encriptación mediante técnicas de correlación puede implementarse: en forma analógica, en memorias holográficas almacenadas en cristales fotorrefractivos y mediante técnicas digitales. Los medios fotorrefractivos que no requieren procesamiento previo para leer la información en ellos registrada, permiten el almacenamiento holográfico múltiple (modificando el ángulo de registro, el estado de polarización, empleando pupilas de múltiples aberturas, etc). Se estudiaron arreglos ópticos de encriptación basados en correladores 4f y de transformada conjunta (JTC). Una ventaja significativa de los correladores tipo JTC es que no requieren el cálculo de una nueva función filtro cada vez que la imagen de referencia cambia y por otra parte prácticamente no necesitan alineación. Es de destacar que actualmente la mayoría de las técnicas de almacenamiento de múltiples datos encriptados se basan en el uso de correladores convergentes tipo 4f, sin embargo en la arquitectura del JTC no ha sido aún aprovechada la alta capacidad de almacenamiento de los medios de registro volumétricos como los cristales fotorrefractivos. Se estudiaron técnicas de encriptación múltiple que empleen las arquitecturas antes mencionadas. En particular, se analizaron la posibilidad de almacenar múltiples datos a partir del cambio de la longitud de onda de registro en la arquitectura JTC. Es esencial en este caso que todos los datos almacenados se puedan recuperar selectivamente y sin solapamiento de la información. Se analizaron los eventuales entrecruzamientos (solapamientos) e identificando los parámetros que controlan este proceso. Este estudio fue el punto de partida para el almacenamiento de imágenes a color. Otra propuesta consistió en el empleo de una versión modificada del correlador de transformada conjunta que emplea un arreglo de múltiples aberturas. Esta propuesta unida al almac
The mathematical analysis for peristaltic flow of nano fluid in a curved channel with compliant walls
S. Nadeem,E. N. Maraj
Applied Nanoscience , 2013, DOI: 10.1007/s13204-012-0165-x
Abstract: In the present paper, we have investigated the peristaltic flow of nano fluid in a curved channel with compliant walls. The governing equations of nano fluid model for curved channel are derived including the effects of curvature. The highly nonlinear partial differential equations are simplified using the long wave length and low Reynolds number assumptions. The reduced nonlinear partial differential equation is solved analytically with the help of homotopy perturbation method. The physical features of pertinent parameters have been discussed by plotting the graphs of pressure rise, velocity, temperature, nano particle volume fraction and stream functions.
Caracteriza??o química e nutricional de plasteína produzida a partir de hidrolisado pancreático de isolado protéico de soja
Martins, Myrian Thereza Serra;
Ciência e Tecnologia de Alimentos , 2005, DOI: 10.1590/S0101-20612005000400010
Abstract: the objective of this research was to characterize chemically the plastein produced from a pancreatic hydrolysate of soy protein isolate (spi). the spi hydrolysate was obtained by an enzymatic discontinuous process, with a 5% substrate concentration, an enzyme/substrate ratio of 1/20, 37oc, 6 hours under constant stirring. the plastein was produced from this hydrolysate with a 40% substrate (w/v), ph 7, 37oc, for 24 hours without stirring. the protein profile was analyzed by gel electrophoresis (sds-page) and by molecular exclusion chromatography (mec). the sds-page did not permit the bands visualization. the mec pointed that the spi hydrolysate presented 5 zones in the region between 5.4 and 66.2 kda while plastein presented 2 zones in the mw of 9.6 and 58.7 kda. the amino acid scoring showed that the limiting amino acids were the sulfur-containing amino acids; reference values of 93.2 and 96.4% were observed for the hydrolysate and plastein, respectively. the enzymatic modification through the plastein synthesis reaction showed to be a viable process for production of raw material in food formulation for clinical nutrition and other systems, but it should be supplemented when used exclusive source protein.
