Growth and characterization of horizontally suspended CNTs across TiN electrode gaps.

2010

A technique is proposed to grow horizontal carbon nanotubes (CNTs) bridging metal electrodes and to assess their electrical properties. A test structure was utilized that allows for selective electrochemical sidewall catalyst placement. The selectivity of the technique is based on the connection of the desired metal electrodes to the silicon substrate where the potential for electrochemical deposition was applied. Control over the Ni catalyst size (15-30 nm) and density (up to 3 x 10(11) particles cm(-2)) is demonstrated. Horizontal CNTs with controlled diameter and density were obtained by CVD growth perpendicular to the sidewalls of patterned TiN electrode structures. Electrode gaps with …

Interstitial defects in diamond: A quantum mechanical simulation of their EPR constants and vibrational spectra

2020

The local geometry, electronic structure, and vibrational features of three vicinal double interstitial defects in diamond, ICIC, ICIN, and ININ, are investigated and compared with those of three "simple" ⟨100⟩ interstitial defects, ICC, ICN, and INN, previously reported by Salustro et al. [Phys. Chem. Chem. Phys. 20, 16615 (2018)], using a similar quantum mechanical approach based on the B3LYP functional constructed from Gaussian-type basis sets, within a supercell scheme, as implemented in the CRYSTAL code. For the first time, the Fermi contact term and hyperfine coupling tensor B of the four open shell structures, ICIC, ICIN, ICC, and ICN, are evaluated and compared with the available ex…

Chemical disorder and Pb207 hyperfine fields in the magnetoelectric multiferroic Pb(Fe1/2Sb1/2)O3 and its solid solution with Pb(Fe1/2Nb1/2)O3

2018

We report on the results of magnetic susceptibility, electron paramagnetic resonance, and $^{207}\mathrm{Pb}$ nuclear magnetic resonance (NMR) studies of the magnetoelectric multiferroic $\mathrm{Pb}(\mathrm{F}{\mathrm{e}}_{1/2}\mathrm{S}{\mathrm{b}}_{1/2}){\mathrm{O}}_{3}$ (PFS) ceramic, as well as its solid solution with $\mathrm{Pb}(\mathrm{F}{\mathrm{e}}_{1/2}\mathrm{N}{\mathrm{b}}_{1/2}){\mathrm{O}}_{3}$ (PFN) of different degrees of the 1:1 ordering of magnetic $\mathrm{F}{\mathrm{e}}^{3+}$ and nonmagnetic $\mathrm{S}{\mathrm{b}}^{5+}$ ions. The ordering has been studied by x-ray diffraction (XRD) and NMR methods. In particular, two spectral lines, originating from the ordered and dis…

Hospitalisation and length of hospital stay following first-episode psychosis:Systematic review and meta-analysis of longitudinal studies

2019

AbstractBackgroundReducing hospitalisation and length of stay (LOS) in hospital following first episode psychosis (FEP) is important, yet reliable measures of these outcomes and their moderators are lacking. We conducted a systematic review and meta-analysis to investigate the proportion of FEP cases who were hospitalised after their first contact with services and the LOS in a hospital during follow-up.MethodsStudies were identified from a systematic search across major electronic databases from inception to October 2017. Random effects meta-analyses and meta-regression analyses were conducted.Results81 longitudinal studies encompassing data for 23 280 FEP patients with an average follow-u…

Introduction: Music, from Intangible Cultural Heritage to the Music Industry

2021

AbstractOur first contact with music is almost certainly in our childhood when our parents sing lullabies to us at bedtime. In a community where music is important, these songs are likely to be successfully transmitted from one generation to the next. This is similar to the concept of intangible cultural heritage and how it is transmitted.

Good English Pronunciation Users and Their Pronunciation Learning Strategies

2015

The study investigates pronunciation learning strategies (PLS) deployed by those with good English pronunciation, as well as their beliefs concerning the variables that affect pronunciation competence. In order to collect data for analysis this study surveyed 61 participants who had learned English as a foreign language. They comprised 28 higher education teachers and scholars specialising in English phonetics and phonology, who were defined as good pronunciation users (GPU), and 33 EFL teacher training students, viewed as average pronunciation learners (APL). This cohort responded to a survey on pronunciation learning strategies and expressed their views on several aspects affecting the L2…

Family and Affective Models in Children's Literature. An Approach from the Texts for Early Readers at Valencian Schools

2015

Abstract In previous researches we have offered a panoramic view about the presence of family structures different from the traditional one in children's literature, (Oltra Albiach, 2011), about the (shy) presence of protagonists with homo-parent, single- parent families reconstructed or intercultural in children's titles and about the publications of these characteristics in the literature for first readers that have seen the light in recent years (Oltra Albiach & Pardo Coy, 2013). It is noted that the introduction of these literatures in initial schools remains in general a pending matter, especially if we take into account that it is an ideal level to prevent and treat stereotypes and pr…

Integrated Treatment Model for First-Contact Patients with a Schizophrenia-Type Psychosis: The Finnish API Project

1996

This paper presents the background, rationale, set-up and first results of the Finnish API study, whose aim was to investigate the use of a psychotherapeutically oriented and familycentred treatment model for acute psychosis in different treatment settings, and especially the role of neuroleptic drug treatment when working along the principles of the integrated treatment model. Six psychiatric catchment areas from different parts of the country participated by collecting a material of 136 first-contact patients with a schizophrenia-type psychosis. More than half of the patients received a formal diagnosis from the schizophrenia group at the initial examination, and more than one-third a dia…

Populismo municipal y nacionalcatolicismo en la Valencia del general Primo de Rivera: el marqués de Sotelo (1923-1930) = Populism and Municipal Propa…

2016

El presente trabajo pretende explicar las principales características políticas del régimen de Primo de Rivera en la ciudad de Valencia. Desde un análisis de la política municipal, el populismo y la publicidad de la construcción de obras públicas se presentan como los principales pilares para la consolidación del régimen en Valencia. La praxis política del marqués de Sotelo supuso para la ciudad el primer contacto con el nacionalcatolicismo. La figura de este alcalde, además, ocupa buena parte del texto al ser un fiel exponente de las prácticas políticas nacidas tras el golpe de septiembre de 1923.This paper aims to explain the main features of the political regime of Primo de Rivera in the…

Frisian as an Endangered Language: An Overview

2019

The main goal of the paper is to answer the questions whether Frisian can be referred to as an endangered language and if it managed to survive the constant influence of the surrounding larger cultures and languages. The first point to be analyzed is the geographic distribution of Frisian. The second issue to be considered is the historical and present cultural and social status of the Frisian language. The third matter to be analysed is the lexical variety of Frisian language and its complexity, which made its survival possible. The article takes the diachronic perspective and expounds upon all the mentioned factors and their role in the preservation of Frisian until today. The paper prese…
