SiCILIA-Silicon Carbide Detectors for Intense Luminosity Investigations and Applications.

Silicon carbide (SiC) is a compound semiconductor, which is considered as a possible alternative to silicon for particles and photons detection. Its characteristics make it very promising for the next generation of nuclear and particle physics experiments at high beam luminosity. Silicon Carbide detectors for Intense Luminosity Investigations and Applications (SiCILIA) is a project starting as a collaboration between the Italian National Institute of Nuclear Physics (INFN) and IMM-CNR, aiming at the realization of innovative detection systems based on SiC. In this paper, we discuss the main features of silicon carbide as a material and its potential application in the field of particles and photons detectors, the project structure and the strategies used for the prototype realization, and the first results concerning prototype production and their performance.

Análisis del ángulo de convexidad facial en fotografías de niños de la Clínica Estomatológica Central de la Universidad Peruana Cayetano Heredia / Analysis of the facial convexity angle, in children from the Clinica Estomatologica Central of Cayetano Heredia Peruvian University

El propósito del presente estudio fue determinar el ángulo de convexidad facial, en niños / as de la Clínica Estomatológica Central de la UPCH respecto a estadios de dentición y compararlos en oclusión normal y maloclusiones según Angle. La población muestral quedó constituida por 475 registros de pacientes ortodónticos de 3 a 13 años, de la base de datos del Departamento Académico de Estomatología del Niño y del adolescente (DAENA) de la Facultad de Estomatología de la UPCH, entre los años 2006-2010. Se midieron las fotografías de perfil, encontrándose promedios y rangos para dicho ángulo. El rango del ángulo de convexidad facial en niños y niñas con normoclusión y maloclusión clase I es de 160.7 - 171.8, lo cual se podría extrapolar a la población peruana. Para maloclusiones clase II-1 y III los rangos fueron de 155.4-167.2 y 169.6-183.7 respectivamente, paea este estudio. Las pruebas estadísticas ANOVA, t-student y HSD Tukey, demuestran que hubo diferencias significativas para el promedio de dicho ángulo entre maloclusiones de clase I y II-1, entre maloclusiones clase II-1 y II-2, y entre maloclusión clase III y las demás maloclusiones. Asimismo, no se encontraron diferencias estadísticamente significativas entre sexos.

The purpose of this study was to evaluate the facial convexity angle, in children from the "Clínica Estomatológica Central" of UPCH, with respect to dentition stages, normal occlusion and Angle's malocclusions. 475 charts from orthodontic patients, between 3 to 13 years old, were evaluated. These files were obtained from DAENA's (Departamento Académico de Estomatología del Niño y del Adolescente) database, of the Dentistry Faculty of UPCH, between 2006 to 2010. Profile photographs were measured, and means and ranges for this angle were found. The facial convexity angle's range for children with normal occlusion and Class I maloclussion was 160.7 - 171.8, which can be extrapolated to the Peruvian population. For Class II-1 and Class III maloclussions the ranges were 155.4-167.2 y 169.6-183.7 respectively, for this study. Statistical tests like ANOVA, t-student and HSD Tukey, showed no differences for the facial convexity angle's mean between Class I and Class II-1 malocclusion, between Class II-1 and Class II-2 malocclusions and between Class III and the rest of malocclusions. Also, there were no distinct gender differences.

Behavioral and socio-emotional functioning in children with selective mutism: a comparison with anxious and typically developing children across multiple informants.

We examined differences among 158 children, 44 with selective mutism (SM; M = 8.2 years, SD = 3.4 years), 65 with mixed anxiety (MA; M = 8.9 years, SD = 3.2 years), and 49 community controls (M = 7.7 years, SD = 2.6 years) on primary caregiver, teacher, and child reports of behavioral and socio-emotional functioning. Children with SM were rated lower than controls on a range of social skills, but the SM and MA groups did not significantly differ on many of the social skills and anxiety measures. However, children with SM were rated higher than children with MA and controls on social anxiety. Findings suggest that SM may be conceptualized as an anxiety disorder, with primary deficits in social functioning and social anxiety. This interpretation supports a more specific classification of SM as an anxiety disorder for future diagnostic manuals than is currently described in the literature. The present findings also have implications for clinical practice, whereby social skills training merits inclusion in intervention for children with anxiety disorders as well as children with SM.
