Long-Term Efficacy of Psychosocial Treatments for Adults With Attention-Deficit/Hyperactivity Disorder: A Meta-Analytic Review

2018

Background: Recent evidence suggests that psychosocial treatments, particularly cognitive-behavioral therapy (CBT), are effective interventions for adult attention deficit hyperactivity disorder (ADHD). The objective of this review was to determine the long-term efficacy of psychosocial interventions in improving clinically relevant variables, including ADHD core symptoms, clinical global impression (CGI), and global functioning. Methods: In total, nine randomized controlled trials and three uncontrolled single-group pretest-posttest studies were included. The data from these studies were combined using the inverse variance method. Heterogeneity and risk of bias were assessed. Subgroup anal…

Apical seal comparison of low-temperature thermoplasticized gutta-percha technique and lateral condensation with two different master cones

2007

Aim: To compare the apical sealing in mesio-buccal canals of extracted molars obturated with low-temperature thermoplasticized gutta-percha or cold lateral condensation techniques using a .06 or a .02 mm/mm tapered gutta-percha master cone. The secondary aim was to evaluate the depth of spreader penetration in root canals using a .06 or a .02 mm/mm tapered gutta-percha master cone. Methodology: Forty-four mesio-buccal curved canals (25-40º) were instrumented with .06 nickel-titanium rotary instruments and randomly distributed into two control groups (n=4) and three experimental groups (n=12) for obturation by the Ultrafil® 3D system or by cold lateral condensation with .06 or .02 tapered ma…

A Methodology for Protection of Trees Against Lightning Strikes as a Measure to Prevent Fires and Loss of Human Life

2021

Some regions may be characterized by a very low annual lightning ground flash density, and yet lightning strikes seem to have been in those areas the cause of widespread wildfires in forested areas. Due to global climate change, these occurrences seem to be an increasing threat. In this paper, the authors discuss the withstand capability of trees against lightning and introduce the criteria for the deployment of tree lightning protection systems (TLPS) to protect forested areas, where deemed necessary by the tree risk assessment. This work analytically identifies the critical trunk radius of the tree below which the tree may explode in the case of a lightning strike and ignite the surroundi…

Functional CdSe and CdSe/ZnS nanoparticles capped with thiols: photophysical and photochemical properties and applications as sensors

2013

Esta tesis se centra en el efecto simbiótico entre los QDs de CdSe o CdSe/ZnS y sus ligandos orgánicos, y las ventajas de este efecto para mejorar la funcionalidad del QD y/o del ligando, o crear una nueva funcionalidad del sistema. Así : 1. la superficie de las nanopartícula recubierta con ligandos orgánicos puede permitir al QD i) permanecer estable en disolventes orgánicos o acuosos, debido a la repulsión estérica o iónica entre las nanopartículas, ii) mantener o aumentar sus propiedades emisivas (pasivación de los defectos de superficie, aumento de distancia entre nanopartícula y moléculas desactivadoras), y/o iii) para proporcionar funcionalidad a la nanopartícula. 2. la forma esférica…

Influence of Mn site doping on electrical resistivity of polycrystalline La1-yAyMn1-xBxO3 (A=Ba, Sr; B=Cu, Cr, Co) Manganites

2008

We have the measured electrical resistivity of La1-yBayMn1-xCuxO3 (0.17?y?0.30; 0.04?x?0.10), La1-ySryMn1-xCrxO3 and La1-ySryMn1-xCoxO3 (0.270?y?0.294; 0.02?x?0.10) polycrystalline samples in the 25-325 K temperature range. The increase of Mn site doping concentration leads to an increase of the electrical resistivity of the samples and the appearance of a ?double-peak? structure in the electrical resistivity versus temperature graphs. The first peak represents the insulator-metal transition in vicinity of the paramagnetic-ferromagnetic transition (TC). We have found that the intensity of the second peak increases with an increase of concentration of Mn substituents, due to the hole scatter…

El síndrome de Langer Giedion, de Cornelia de Lange y comorbilidad: una revisión bibliográfica

2015

Los Síndromes de Langer Giedion (LGS) y el de Cornelia de (CdLS) son síndromes congénitos raros, causados por una alteración cromosómica y pueden aparecer comórbidos. Ambos se caracterizan por anormalidades esqueléticas, retraso del crecimiento, rasgos faciales distintivos y específicos, y discapacidad intelectual en severidad variable. Se presenta una revisión bibliográfica, de artículos publicados en el periodo 2010-2015, sobre ambos síndromes y su comorbilidad. Se han seleccionado para su análisis 33 artículos, con el objetivo de determinar el estado de la literatura científica actual. En los resultados se observa cómo las publicaciones relacionadas con estos síndromes pertenecen en su m…

Competencias socioemocionales, toma de decisiones y conducta antisocial-delictiva en adolescentes: Un estudio transcultural

2021

Las competencias socioemocionales y la toma de decisiones son temas de interés para prevenir e intervenir en las conductas antisociales y delictivas de los adolescentes. Una mayor competencia socioemocional se ha relacionado con una mejor salud mental, bienestar subjetivo, conducta prosocial y ajuste social. La toma de decisiones está relacionada con las conductas de riesgo positivas y negativas, el rendimiento personal y social y el logro de metas. La evidencia sugiere que los adolescentes ofensores tienen un menor rendimiento en las competencias socioemocionales y en la toma de decisiones que sus compañeros normativos. El objetivo principal de este estudio fue desarrollar las competencias…

Alkylsilyl compounds as enablers of atomic layer deposition: analysis of (Et3Si)3As through the GaAs process

2016

A new chemistry has been developed to deposit GaAs, the quintessential compound semiconductor. The ALD process is based on a dechlorosilylation reaction between GaCl3 and (Et3Si)3As. Characteristic ALD growth was demonstrated, indicating good applicability of the alkylsilyl arsenide precursor. ALD of GaAs produced uniform, amorphous and stoichiometric films with low impurity content. This was done with saturating growth rates and an easily controlled film thickness. Crystallization was achieved by annealing. Even though the growth rate strongly decreased with increasing deposition temperature, good quality film growth was demonstrated at 175 to 200 °C, indicating the presence of an ALD wind…

Progress in the Development of CdTe and CdZnTe Semiconductor Radiation Detectors for Astrophysical and Medical Applications

2009

Over the last decade, cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) wide band gap semiconductors have attracted increasing interest as X-ray and gamma ray detectors. Among the traditional high performance spectrometers based on silicon (Si) and germanium (Ge), CdTe and CdZnTe detectors show high detection efficiency and good room temperature performance and are well suited for the development of compact and reliable detection systems. In this paper, we review the current status of research in the development of CdTe and CdZnTe detectors by a comprehensive survey on the material properties, the device characteristics, the different techniques for improving the overall detector…

Habilidades lingüísticas y ejecutivas en el Trastorno por Déficit de Atención (TDAH) y en las Dificultades de Comprensión Lectora (DCL)

2011

Resumen tomado de la publicación El objetivo de este trabajo fue estudiar la posible especificidad de déficits en el funcionamiento lingüístico y ejecutivo de estudiantes con TDAH y con DCL y conocer el perfil de déficits del grupo comórbido (TDAH+DCL). Participaron en el estudio 84 chicos entre 12 a 16 años divididos en cuatro grupos con un número igual de sujetos (N= 21): TDAH, DCL, TDAH +DCL, y grupo de comparación (sin TDAH y sin DCL). Se midió el vocabulario, comprensión oral, acceso al léxico, memoria verbal y espacial, atención e inhibición. Los resultados indican que el grupo TDAH+DCL presenta los déficits lingüísticos más importantes seguido del grupo con DCL. Por otro lado, los tr…
