Adenoma pleomorfo del septum nasal, dos casos clínicos y revisión del tema

Indexación: ScieloEl tumor benigno más frecuente de las glándulas salivales mayores es el adenoma pleomorfo. Además de las glándulas salivales mayores, también puede ocurrir en las glándulas salivales del paladar duro y blando. Raros casos se han reportado en la nasofaringe, orofaringe, hipofaringe y laringe. Adenomas pleomorfos intranasales son muy infrecuentes y pueden ser mal diagnosticados debido a que tienen mayor celularidad mioepitelial y poco estroma mixoide, en comparación con los que se localizan en otros lugares. Presentamos dos raros casos de adenomas pleomorfos del septum nasal y analizamos los hallazgos patológicos y el manejo clínico. Se revisa la literatura en relación al tema.The most common benign tumor of major salivary glands is the pleomorphic adenoma. In addition to the major salivary glands may also occur in the salivary glands of hard and soft palate. Rare cases have been reported in the nasopharynx, oropharynx, hypopharynx and larynx. Intranasal pleomorphic adenomas are very rare and can be misdiagnosed because they have greater myoepithelial cellularity and little myxoid stroma, compared with those located elsewhere. We report two rare cases of pleomorphic adenomas of the nasal septum and analyze the pathological findings and clinical management. We review the literature on the subject.http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-48162011000100010&nrm=is

La variabilidad en el razonamiento probabilístico informal de estudiantes de bachillerato

En esta comunicación se exploran las respuestas de los estudiantes a dos tareas binomiales, de predicción y de distribución, para conocer cómo expresan la variabilidad en sus predicciones antes y después de actividades de simulación. Para la recolección de datos, se realizó un estudio de cuatro etapas con dos grupos de estudiantes, uno que no había tomado un curso de probabilidad y estadística, y otro que había tomado uno. La primera y cuarta etapa consistió en aplicar un cuestionario relacionado con una situación binomial b(x, 2, ½). En la segunda y tercera etapa, los estudiantes llevaron a cabo simulaciones físicas y con el software Fathom, respectivamente. En el análisis se destacan las dificultades que enfrentan los estudiantes en la integración de la variabilidad en sus razonamientos, a pesar de su experiencia con la simulación. Se proponen dos categorías para describir patrones de respuesta: dogmatismo teórico y compromiso empírico

Constructions of the soluble potentials for the non-relativistic quantum system by means of the Heun functions

The Schr\"{o}dinger equation $\psi"(x)+\kappa^2 \psi(x)=0$ where $\kappa^2=k^2-V(x)$ is rewritten as a more popular form of a second order differential equation through taking a similarity transformation $\psi(z)=\phi(z)u(z)$ with $z=z(x)$. The Schr\"{o}dinger invariant $I_{S}(x)$ can be calculated directly by the Schwarzian derivative $\{z, x\}$ and the invariant $I(z)$ of the differential equation $u_{zz}+f(z)u_{z}+g(z)u=0$. We find an important relation for moving particle as $\nabla^2=-I_{S}(x)$ and thus explain the reason why the Schr\"{o}dinger invariant $I_{S}(x)$ keeps constant. As an illustration, we take the typical Heun differential equation as an object to construct a class of soluble potentials and generalize the previous results through choosing different $\rho=z'(x)$ as before. We get a more general solution $z(x)$ through integrating $(z')^2=\alpha_{1}z^2+\beta_{1}z+\gamma_{1}$ directly and it includes all possibilities for those parameters. Some particular cases are discussed in detail.Comment: 11 page

Simultaneous Identification of the Diffusion Coefficient and the Potential for the Schr\"odinger Operator with only one Observation

This article is devoted to prove a stability result for two independent coefficients for a Schr\"odinger operator in an unbounded strip. The result is obtained with only one observation on an unbounded subset of the boundary and the data of the solution at a fixed time on the whole domain

Habitability: CAMELOT 4

During 1988 to 1989 the NASA/USRA Advanced Design Program sponsored research and design efforts aimed at developing habitability criteria and at defining a habitability concept as a useful tool in understanding and evaluating dwellings for prolonged stays in extraterrestrial space. The Circulating Auto sufficient Mars-Earth Luxurious Orbital Transport (CAMELOT) was studied as a case in which the students would try to enhance the quality of life of the inhabitants by applying architectural design methodology. The study proposed 14 habitability criteria considered necessary to fulfill the defined habitability concept, which is that state of equilibrium that results from the interaction between components of the Individual Architecture Mission Complex, which allows a person to sustain physiological homeostatis, adequate performance, and acceptable social relationships. Architecture, design development, refinements and revisions to improve the quality of life, new insights on artificial gravity, form and constitution problems, and the final design concept are covered

Desarrollo del razonamiento sobre pruebas de significación de estudiantes de bachillerato en un ambiente tecnológico

Se describe el desarrollo del razonamiento de 36 estudiantes de bachillerato, organizados en parejas, acerca de la técnica de pruebas de significación estadística con el apoyo de un software educativo de estadística (Fathom); dicho desarrollo es visto a través de sus respuestas a 4 problemas de pruebas de significación; estos se resolvieron en sendas sesiones en las que además se realizaron cortas intervenciones del profesor, se enseñó a utilizar el software y se discutieron dudas de los problemas vistos en la sesión previa respectiva. Las respuestas a cada problema se clasificaron en niveles SOLO. Los resultados muestran avances en la calidad de las respuestas de los participantes, superándose en cada actividad algunos errores cometidos en la previa, esto lleva conjeturar que los estudiantes se van apropiando del esquema de pruebas de significación. No obstante, se presentan algunas dificultades similares a las ya reportadas en la literatura

Studying the impact of biomass burning aerosol radiative and climate effects on the Amazon rainforest productivity with an Earth system model

Diffuse light conditions can increase the efficiency of photosynthesis and carbon uptake by vegetation canopies. The diffuse fraction of photosynthetically active radiation (PAR) can be affected by either a change in the atmospheric aerosol burden and/or a change in cloudiness. During the dry season, a hotspot of biomass burning on the edges of the Amazon rainforest emits a complex mixture of aerosols and their precursors and climate-active trace gases (e.g. CO2, CH4, NOx). This creates potential for significant interactions between chemistry, aerosol, cloud, radiation and the biosphere across the Amazon region. The combined effects of biomass burning on the terrestrial carbon cycle for the present day are potentially large, yet poorly quantified. Here, we quantify such effects using the Met Office Hadley Centre Earth system model HadGEM2-ES, which provides a fully coupled framework with interactive aerosol, radiative transfer, dynamic vegetation, atmospheric chemistry and biogenic volatile organic compound emission components. Results show that for present day, defined as year 2000 climate, the overall net impact of biomass burning aerosols is to increase net primary productivity (NPP) by +80 to +105 TgC yr−1, or 1.9 % to 2.7 %, over the central Amazon Basin on annual mean. For the first time we show that this enhancement is the net result of multiple competing effects: an increase in diffuse light which stimulates photosynthetic activity in the shaded part of the canopy (+65 to +110 TgC yr−1), a reduction in the total amount of radiation (−52 to −105 TgC yr−1) which reduces photosynthesis and feedback from climate adjustments in response to the aerosol forcing which increases the efficiency of biochemical processes (+67 to +100 TgC yr−1). These results illustrate that despite a modest direct aerosol effect (the sum of the first two counteracting mechanisms), the overall net impact of biomass burning aerosols on vegetation is sizeable when indirect climate feedbacks are considered. We demonstrate that capturing the net impact of aerosols on vegetation should be assessed considering the system-wide behaviour

Vegetation distribution and terrestrial carbon cycle in a carbon cycle configuration of JULES4.6 with new plant functional types

This is the final version. Available on open access from EGU via the DOI in this recordDynamic global vegetation models (DGVMs) are used for studying historical and future changes to vegetation and the terrestrial carbon cycle. JULES (the Joint UK Land Environment Simulator) represents the land surface in the Hadley Centre climate models and in the UK Earth System Model. Recently the number of plant functional types (PFTs) in JULES was expanded from five to nine to better represent functional diversity in global ecosystems. Here we introduce a more mechanistic representation of vegetation dynamics in TRIFFID, the dynamic vegetation component of JULES, which allows for any number of PFTs to compete based solely on their height; therefore, the previous hardwired dominance hierarchy is removed. With the new set of nine PFTs, JULES is able to more accurately reproduce global vegetation distribution compared to the former five PFT version. Improvements include the coverage of trees within tropical and boreal forests and a reduction in shrubs, the latter of which dominated at high latitudes. We show that JULES is able to realistically represent several aspects of the global carbon (C) cycle. The simulated gross primary productivity (GPP) is within the range of observations, but simulated net primary productivity (NPP) is slightly too high. GPP in JULES from 1982 to 2011 is 133PgCyrg'1, compared to observation-based estimates (over the same time period) between 1238 and 150-175PgCyrg'1. NPP from 2000 to 2013 is 72PgCyrg'1, compared to satellite-derived NPP of 55PgCyrg'1 over the same period and independent estimates of 56.214.3PgCyrg'1. The simulated carbon stored in vegetation is 542PgC, compared to an observation-based range of 400-600PgC. Soil carbon is much lower (1422PgC) than estimates from measurements ( > 2400PgC), with large underestimations of soil carbon in the tropical and boreal forests. We also examined some aspects of the historical terrestrial carbon sink as simulated by JULES. Between the 1900s and 2000s, increased atmospheric carbon dioxide levels enhanced vegetation productivity and litter inputs into the soils, while land use change removed vegetation and reduced soil carbon. The result is a simulated increase in soil carbon of 57PgC but a decrease in vegetation carbon of 98PgC. The total simulated loss of soil and vegetation carbon due to land use change is 138PgC from 1900 to 2009, compared to a recent observationally constrained estimate of 15550PgC from 1901 to 2012. The simulated land carbon sink is 2.01.0PgCyrg'1 from 2000 to 2009, in close agreement with estimates from the IPCC and Global Carbon Project.The authors acknowledge support from the Natural Environment Research Council (NERC) Joint Weather and Climate Research Programme through grant numbers NE/K016016/1 (Anna B.
