Single-Polarization Double Refraction in Plasmonic Crystals: Considerations on Energy Flow

We examined the optical properties of nanolayered metal-dielectric lattices. At subwavelength regimes, the periodic array of metallic nanofilms demonstrates nonlocality-induced double refraction, conventional positive and as well as negative. In particular, we report on energy-flow considerations concerning both refractive behaviors concurrently. Numerical simulations provide transmittance of individual beams in Ag-TiO2 metamaterials under different configurations. In regimes of the effective-medium theory predicting elliptic dispersion, negative refraction may be stronger than the expected positive refraction.

Dyslipidemia and blood lipid levels in patients tratied in primary care centers in east SAN JOSE

Dyslipidemia, i.e. high levels of blood lipids (cholesterol and triglycerides), is strongly related to cardiovascular disease (CVD). In order to reduce the risk of CVD at any moment in a person ́s life, it is crucial to know his/her –and the population’s– lipid profile. The aim of this study was to assess the (statistical) indicators of blood lipids and the prevalence of dyslipidemia in patients treated in the Integral Health Attention Program from Universidad de Costa Rica. A descriptive study was conducted including 10,044 patients aged 20 to 65 years, who were tested for a blood lipid profile in 2006. A total of 2,969 (29.6%) male and 7,075 (70.4%) female patients took part in the study, with an average age of 43.5 years. General averages for blood lipids were: 203.3 mg/dl for total cholesterol, 50.1 mg/dl for HDL, 120.1 mg/dl for LDL, and 165.6 mg/dl for triglycerides. Prevalence of 17.2% was determined for hypercholesterolemia (≥240 mg/dl), as well as 21.3% for low HDL levels (<40 mg/dl), 11.9% for high LDL levels (≥160 mg/dl), and 26.3% for high triglyceride levels (≥200 mg/dl). Women showed higher overall levels of dyslipidemia than men. Based on health areas, no significant differences were found in general lipid levels by age or sex. Results indicate that the general prevalence of dyslipidemia is close to half the rate reported in worldwide literature and lower than results reported in Costa Rican studies. However, general averages exceeded optimal levels for each blood lipid; consequently, it is important to develop health interventions oriented to reduce the impact of dyslipidemia in the studied population.

Nenneguya garavelli n. sp and Myxobolus peculiaris n. sp (Myxozoa : Myxobolidae) in the gills of Cyphocharax nagelli (Osteichthyes : Curimatidae) from Rio do Peixe Reservoir, Sao Jose do Rio Pardo, São Paulo, Brazil

The present work describes myxozoans found in Cyphocharax nagelli (Characiformes: Curimatinae) commonly called saguiru collected from Rio do Peixe Reservoir, Sao Jose do Rio Pardo, São Paulo, Brazil. From a total of 38 examined fish, 24 were infected with Henneguya garavelli n. sp. (63% prevalence) and two with Myxobolus peculiaris n. sp. (5% prevalence) in the gills. Spores were studied by staining and fresh spores were observed by differential interference contrast optics. Henneguya garavelli n. sp. differs from Henneguya iheringi , Henneguya occulta, Henneguya cesarpintoi, Henneguya santae, Henneguya pisciforme, Henneguya amazonica, Henneguya striolata, Henneguya leporinicola and Henneguya chydadea in spore length and from Henneguya travassosi, Henneguya adherens, Henneguya malabarica, Henneguya piaractus and also Henneguya chydadea in polar capsule length and tail length. Myxobolus peculiaris n. sp. was very different when compared to other species of Myxobolus in its morphology and the biggest size of spore body. The authors present tables with comparative measurements of Brazilian myxozoan parasites. (c) 2006 Elsevier B.V. All rights reserved.

El teatro cómico de Enrique García Álvarez

Enrique García Álvarez (Madrid, 1883-1931) belonged to the group of writers who stood out in the late nineteenth century and early twentieth in what was known as “género chico”, label used to oppose this kind of theater to the dramaturgy considered serious. It was composed of brief and comic works whose intention was to generate a fun time for the spectators. Our author was one of the leading representatives and his numerous creations appeared profusely in the posters of the theaters per hour. In the twentieth century, he adapted to the new forms imposed on the scene. Despite his enormous fame at the time, nowadays Enrique García Álvarez remains completely unknown, not only in the eyes of the general public but also to the more knowledgeable circles of our literature. Studies of his dramatic work are almost nonexistent and basically limited to their collaborations with other authors who had more luck as Arniches or Muñoz Seca. The purpose of this thesis is, therefore, to complete a thorough study of the figure and production of Enrique García Álvarez, as well as its impact on the literature. The opening chapter is a reconstruction of the life and work of the author. In the following chapters, we proceeded to the analysis of structural features such as theme, time, space, and characters of his dramatic world. At the end of these pages, we have included a photographic appendix that illustrates some moments of his personal and professional career. We have also developed appendices to classify his librettos chronologically, by collaborator and by genre...

Metabolic syndrome and associated factors in a population-based sample of schoolchildren in Colombia: The FUPRECOL Study

In contrast to the definition of metabolic syndrome (MetS) in adults, there is no standard definition of MetS in pediatric populations. We aimed to assess the differences in the prevalence of MetS in children and adolescents aged 9–17 years in the city of Bogota (Colombia) using four different operational definitions for these age groups and to examine the associated variables. A total of 673 children and 1,247 adolescents attending public schools in Bogota (54.4% girls; age range 9–17.9 years) were included. The prevalence of MetS was determined by the definitions provided by the International Diabetes Federation (IDF) and three published studies by Cook et al., de Ferranti et al., and Ford et al. The prevalence of MetS was 0.3%, 6.3%, 7.8%, and 11.0% according to the IDF, Cook et al., Ford et al., and de Ferranti et al. definitions, respectively. The most prevalent components were low high-density lipoprotein cholesterol and high triglyceride levels, whereas the least prevalent components were abdominal obesity and hyperglycemia. Overall, the prevalence of MetS was higher in obese than in non-obese schoolchildren. In conclusion, MetS diagnoses in schoolchildren strongly depend on the definition chosen. These findings may be relevant to health promotion efforts for Colombian youth to develop prospective studies and to define which cut-offs are the best indicators of future morbidity.

El daño y el nexo causal en la perdida de oportunidad

El presente escrito se ocupa de estudiar el nexo de causalidad como elemento estructural de la responsabilidad cuando éste es difuso. Para ello, se pretende abordar la pérdida de la oportunidad como una teoría especial de causalidad que tiene lugar cuando el nexo causal no resulta claro, lo cual contradice la tesis preponderante de la doctrina y la jurisprudencia tradicional según la cual, la pérdida de la oportunidad es un criterio autónomo del daño. En su contenido se realiza una explicación del por qué se entiende la pérdida de la oportunidad como una teoría especial de causalidad y no como un criterio autónomo de daño, haciendo énfasis en el elemento de certeza que caracteriza al daño. Posteriormente, se advierte del tratamiento que la jurisprudencia le ha dado a la pérdida de la oportunidad. A su turno, el presente documento, indica la naturaleza jurídica de la pérdida de la oportunidad, afirmando que es una inferencia lógica que realiza el juez y no un hecho que altere el estado de las cosas como si sucede con el daño. Finalmente, se aborda la prueba de la teoría de la pérdida de la oportunidad mediante un cálculo de probabilidades y se identifican los pasos para realizar una adecuada reparación integral.

La influencia de los objetivos del milenio del PNUD en la implementación de políticas publicas ambientales en Tailandia para el periodo del 2000 al 2013

La presente investigación tiene como objetivo principal, explicar la influencia de los ODM del PNUD en la implementación de políticas públicas medioambientales de Tailandia en el periodo del 2000 al 2013, basado en la teoría de los complejos de socialización y la transferencia de normas que implican un buen comportamiento medioambiental. De esta manera, demostrar que los agentes socializadores han cumplido un papel fundamental para la implementación de políticas públicas en Tailandia en su interés por cumplir con sus compromisos internacionales. Esta monografía utilizara un método cualitativo, desde el análisis de las fuentes primarias y secundarias, realizando especial énfasis en la teoría de complejos de socialización que permita un análisis descriptivo y explicativo del fenómeno.

ACTIVIDAD SISMICA DE CARACTER SUPERFICIAL REGISTRADA POR LA RED SISMOGRÁFICA DEL OVSICORI-UNA EN LA HOJA DE SAN JOSE 1:200.000 ENTRE ABRIL 1984 - JULIO 1988

Este trabajo es el resultado del análisis de la información existente, registrada por el OVSICORI-UNA para la región del Valle Central de Costa Rica (Hoja San José, escala 1:200.000).  Históricamente el Valle Central ha sufrido por la acción de varios terremotos.  Entre los más dañinos podemos citar el de Cartago de 1841, el de Fraijanes de 1888, el de Cartago de 1910, el de Sarchí de 1912, el de Patillos de 1952 y el de los del Bajos del Toro en 1955.  Esta actividad asociada a fallas de carácter superficial (z 15 km) y con magnitudes moderadas mb 6.5, muy probablemente se volverá a presentar en el futuro, en igual forma en que se han visto afectada la ciudad de San Salvador en la hermana república de El Salvador.  Es, por lo tanto, de vital importancia investigar conocer y evaluar la existencia de las fallas que han ocasionado dichos terremotos.
