Masa intraoral de rápido crecimiento: a propósito de un caso
2005
La aparición de una masa intraoral supone un motivo de consulta frecuente en nuestra especialidad. La mayoría de los casos corresponden a lesiones benignas y, dentro de las malignas, a tumores primarios intraorales. Las metástasis suponen menos del 1 % de las lesiones malignas. Presentamos el caso de una mujer de 86 años de edad, sin antecedentes oncológicos, que acudió a nuestro servicio presentando una masa intraoral asintomática, de crecimiento rápido y volumen considerable, sin otros hallazgos de interés a la exploración. La lesión se acompañaba de erosión ósea subyacente. El resultado de la biopsia fue de adenocarcinoma metastático de probable origen abdominal, si bien el tumor primari…
The role of parental effect and relatedness on early development of vendace and whitefish in short and long winter
2015
Tutkimuksessa testattiin ilmastonmuutoksen vaikutuksia muikun (Coregonus albula) ja siian (C. lavaretus) alkioiden kuolevuuteen, alkioiden kasvuun, kuoriutumisaikaan ja kuoriutumiskokoon. Koejärjestely toteutettiin sekä muikulla että siialla yksilöllisinä ristiinhedelmöityksinä tavoitteena selvittää naaraan ja koiraan vaikutusta sekä niiden yhdysvaikutusta mitattaviin muuttujiin. Sen lisäksi muikun emokalojen sukulaisuutta tutkittiin mikrosatelliittien avulla, jotta nähtäisiin voiko sisäsiitosdepressio selittää eroja jälkeläisten kuolevuudessa eri emoparien välillä. Munia haudottiin lyhyen talven sekä pitkän talven lämpöoloissa. Siian alkioiden kuolleisuus oli huomattavasti alhaisempaa kuin…
SPI/INTEGRAL in-flight performance
2003
The SPI instrument has been launched on-board the INTEGRAL observatory on October 17, 2002. SPI is a spectrometer devoted to the sky observation in the 20 keV-8 MeV energy range using 19 germanium detectors. The performance of the cryogenic system is nominal and allows to cool the 19 kg of germanium down to 85 K with a comfortable margin. The energy resolution of the whole camera is 2.5 keV at 1.1 MeV. This resolution degrades with time due to particle irradiation in space. We show that the annealing process allows the recovery of the initial performance. The anticoincidence shield works as expected, with a low threshold at 75 keV, reducing the GeD background by a factor of 20. The digital …
Questions raised in science education : a Colombian-Spanish comparative study
2016
RESUMEN: La formulación de preguntas es un potente recurso para el aprendizaje de las ciencias. El objetivo del presente trabajo fue evaluar el desarrollo de la competencia metacognitiva por medio de la formulación de preguntas. En este estudio se usaron dos dispositivos experimentales de ciencias con un comportamiento inesperado. Se pidió a los participantes realizar preguntas destinadas a comprender su funcionamiento. La evaluación contrastó el desempeño de estudiantes colombianos con estudiantes españoles equivalentes. Los resultados mostraron que los colombianos formulan significativamente más preguntas en general, y más preguntas de alta calidad, que los estudiantes españoles. Se concl…
Does "whole-word shape" play a role in visual word recognition?
2002
To analyze the impact of outline shape on visual word recognition, the visual pattern of the stimuli can be distorted by size alternation. Contrary to the predictions of models that rely on outline shape (Allen, Wallace, & Weber, 1995), the effect of size alternationwas greater for low-frequency words than for high-frequency words in a lexical decision task (Experiment 1). In Experiment 2, the effect of case type (lowercase vs. UPPERCASE) occurred for low-frequency words, but not for high-frequency words. The effect of neighborhood size was remarkably similar in the two experiments. The results can be readily explained in the framework of a resonance model (Grossberg & Stone, 1986), in whic…
Graphemic complexity and multiple print-to-sound associations in visual word recognition
2005
Max Planck Institute for Psycholinguistics, Nijmegen, The Netherlands It has recently been reported that words containing a multiletter grapheme are processed slower than are words composed of single-letter graphemes (Rastle & Coltheart, 1998; Rey, Jacobs, Schmidt-Weigand, & Ziegler, 1998). In the present study, using a perceptual identification task, we found in Experiment 1 that this graphemic complexity effect can be observed while controlling for multiple print-to-sound associations, indexed by regularity or consistency. In Experiment 2, we obtained cumulative effects of graphemic complexity and regularity. These effects were replicated in Experiment 3 in a naming task. Overall, these r…

Background: The effect of depression on decision-making is an important but still an unsettled issue. Although most studies have reported that clinically depressed participants show worse performance, there are also studies that have shown no or even positive effects. Specifically, von Helversen et al. (2011) were able to document a positive effect of depression on task performance in a sequential decision-making task called the secretary problem (SP). Here, we (1) aimed to replicate this study in an extended version using more trials and (2) modified it by including an additional condition in which negative feedback was given. Method: Eighty-two participants took part. They were split into…
