The accumulation of nitrogen to 14 at.% in the nanosized surface layers of samples of 03Х17Н12М2 stainless steel after implantation of N+ ions, the formation of metal nitrides, mainly CrN chromium nitride, and solid solution introduction has been established. It is shown that implantation of N+ ions using pretreatment by Ar+ and O+ ions leads to a decrease in the maximum nitrogen concentration by 2 or more times. It is assumed that this is due to segregation to the surface layers of iron atoms under irradiation by Ar+ ions and the formation of Cr2O3 chromium oxide and CrOOH chromium hydroxide under irradiation by O+ ions.

The article examines a reflecting lens of a planar ion mirror, formed by a channel, adjoining by normal upon the closing lid of the mirror. The wide flange of the channel and the mirror lid have different potentials, are plane-parallel and are on a small distance between each other. A precise analytical expression for the calculation of the field of the reflecting lens has been found using the method of conformal mapping. It is demonstrated that in the ion mirror with the proposed reflecting lens it is possible to adjust the pre-calculated field distribution to approach the theoretically ideal space-time focusing in a wide range of ion energies.

The results of studies of the parameters of the beam of runaway electrons and X-rays generated in a gas diode at different pressures of atmospheric air are presented. It has been confirmed that the maximum values of the beam current, as well as the x-ray intensity, are recorded at air pressure hundreds Pa. The energy distribution of the beam electrons is determined by the method of attenuation of the beam current using aluminum filters of different thickness. The distribution maximum corresponds to an electron energy of ~ 100 keV. The maximum exposure dose of X-rays behind an anode made of copper foil with a thickness of 30 μm was ~ 107 mR. It was found that when the beam current density is more than 35 A / cm2, the effect of the beam electrons absorbed by the elements of the X-ray detector on the shape and amplitude of the registered signal from the detector is observed.

The dependence of rotational correction terms of the effective dipole moment of H2O molecule on the vibrational quantum number v2 which corresponds to the large amplitude motion is obtained in the numerical calculations. Different dipole surfaces of H2O molecule as well as different intra-molecular potentials were used. The effect of the rotational corrections on the calculated line broadening and line shifts by Ar, Kr, H2 and He pressure was analyzed. It is shown that this effect is significant for a shifting of pure rotational lines and rovibrational lines for which the difference in rotational quantum number Ka from the initial and final states of the transition greater (or equal) to three.

Substituted benzaldehydes widely distributed in nature exhibit antibacterial, anti-inflammatory, antiviral, anti-carcinogenic activity with low toxicity, which make their promising in medicine. The results of an experimental and theoretical study of the spectral-luminescent properties of four neutral forms of hydroxy- and methoxy-substituted benzaldehydes are presented. The absorption spectra of the studied compounds were obtained in hexane and ethanol. Measurements of fluorescence spectra and fluorescence excitation of solutions were carried out in ethanol. Based on quantum chemical calculations, the orbital nature of electronic transitions, the features of the electron density distribution upon excitation and changes in the structure of the compound are determined and the rate constants of photophysical processes are estimated. According to calculations, for all compounds studied, the S1 state is formed by the nπ-type transition, and the intensity of the long-wavelength bands in these compounds is formed by one or two ππ-transitions. The fluorescence quantum yield values are estimated from experimental and theoretical data. As a result of the analysis and comparison of experimental data and the results of quantum chemical calculations it was concluded that the neutral forms of the studied substituted benzaldehydes are not responsible for the observed fluorescence in experiments with ethanol solutions.

An ellipsometric method for reconstruction of the composition profile throughout the thickness in thin mercury-cadmium-telluride nanostructures grown by MBE has been developed. The method is based on ellipsometric data, measured during structure growth and following solution of the inverse ellipsometric problem. For this, a replacement of a part of the inhomogeneous layer by a homogeneous substrate with specially chosen optical constants has been done. Numerical simulation showed the correctness of such replacement and the efficiency of the developed algorithm. Using this method, the active region of the heterostructure consisting of five HgTe quantum wells separated by wide-band CdHgTe spacers has been studied. Using the results of continuous measurements of ellipsometric parameters obtained in situ during structure growth, the composition profiles for all five sequentially grown quantum wells was determined. A high repeatability of the composition distribution through the thickness is shown.

A perovskite solar cells with a photoactive layer of lead methylammonium iodide and a hole transport layer based on a complex of polyaniline and poly(2-acrylamido-2-methyl-1-propanesulfonic acid) were developed for the first time. The power conversion efficiency of the devices obtained corresponds to the known analogues. According to the results of modeling the optical parameters of the cell within the Maxwell-Garnet model, the experimentally observed weak dependence of the power conversion efficiency of the device on the perovskite layer thickness in the range of 350–500 nm is found to result from negligible change in the amount of energy absorbed by the photoactive layer and the exciton generation rate.

The practice of identifying structure of couplings between elements of complex systems from experimental recordings of their oscillations (time series) using the Wiener – Granger causality method has revealed a number of problems that prevent one from obtaining reliable results. In particular, the presence of observational noise can lead to the “effect of spurious coupling”, i.e. to inference of mutual coupling between two elements that are actually coupled in a unidirectional way. A quantitative analysis of this phenomenon is carried out and recommendations allowing one to reduce its probability are presented. It is shown that the effect typically takes place only for large noise levels comparable to the level of observed oscillations. However, we have also singled out less typical situations where the effect occurs at much weaker noise.

The crystallographic characteristics of the K2Sr4Nb10O30 ceramic samples are compared with the surface piezoelectric response data obtained by scanning probe microscopy. The relative magnitudes of the piezoelectric moduli d33 were estimated from the surface piezoresponse amplitudes. Depending on the texture axis orientation relative to the ceramics sample surface they are 62 or 58 times greater than the values for an isotropic sample. The anisotropic lattice deformations caused by the pressure during the hot pressing is one of the sources of the surface giant piezoresponse. The influence of the domain walls and polar nanoregions are discussed.

Published: July 2019

Background

IntelliCare is a modular platform that includes 12 simple apps targeting specific psychological strategies for common mental health problems.

Objective

This study aimed to examine the effect of 2 methods of maintaining engagement with the IntelliCare platform, coaching, and receipt of weekly recommendations to try different apps on depression, anxiety, and app use.

Methods

A total of 301 participants with depression or anxiety were randomized to 1 of 4 treatments lasting 8 weeks and were followed for 6 months posttreatment. The trial used a 2X2 factorial design (coached vs self-guided treatment and weekly app recommendations vs no recommendations) to compare engagement metrics.

Results

The median time to last use of any app during treatment was 56 days (interquartile range 54-57), with 253 participants (84.0%, 253/301) continuing to use the apps over a median of 92 days posttreatment. Receipt of weekly recommendations resulted in a significantly higher number of app use sessions during treatment (overall median=216; P=.04) but only marginal effects for time to last use (P=.06) and number of app downloads (P=.08). Coaching resulted in significantly more app downloads (P<.001), but there were no significant effects for time to last download or number of app sessions (P=.36) or time to last download (P=.08). Participants showed significant reductions in the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) across all treatment arms (P s<.001). Coached treatment led to larger GAD-7 reductions than those observed for self-guided treatment (P=.03), but the effects for the PHQ-9 did not reach significance (P=.06). Significant interaction was observed between receiving recommendations and time for the PHQ-9 (P=.04), but there were no significant effects for GAD-7 (P=.58).

Conclusions

IntelliCare produced strong engagement with apps across all treatment arms. Coaching was associated with stronger anxiety outcomes, and receipt of recommendations enhanced depression outcomes.

Published: July 2019

Background and objectives

CKD is a global public health problem. Some cross-sectional studies have associated environmental melamine exposure with kidney diseases, but evidence is limited.

Design, setting, participants, & measurements

We conducted this prospective cohort study to enroll patients with eGFR≥30 ml/min per 1.73 m2 in 2006–2010. Urinary corrected melamine levels (ratio of urinary melamine to urinary creatinine) were measured by liquid chromatography/tandem mass spectrometry at enrollment. Kidney outcomes included doubling of serum creatinine levels, eGFR decline >3 ml/min per 1.73 m2 per year, and 30% decline in eGFR in the first 2 years. Subjects were followed until targeted kidney outcomes, cancer, death, last contact, or the end of observation in December 2016.

Results

In a total of 293 subjects, the median urinary corrected melamine level was 0.97 (interquartile range, 0.43–2.08) μg/mmol. Over a median follow-up period of 7.0 years, serum creatinine levels doubled in 80 subjects (27%). Subjects in the highest tertile of urinary melamine level 12.70 μg/mmol) had a 2.30 (95% confidence interval, 1.25 to 4.23; P<0.01) hazard risk for doubling of serum creatinine compared with those in the lowest tertile (0.02–0.58 μg/mmol). Similar significant dose-response results were found in eGFR decline >3 ml/min per 1.73 m2 per year and 30% decline in eGFR in the first 2 years.

Conclusions

Urinary melamine level is significantly associated with kidney function deterioration in patients with early-stage CKD.

Resumo: O presente artigo apresenta um relato de experiência de leitura literária, realizada no primeiro ano do ensino médio, do Instituto Federal do Espírito Santo (IFES – campus Piúma) e, ainda, discute alguns aspectos que se tornaram relevantes durante essa prática. Por meio de aulas transformadas em encontros, o projeto de leitura da obra A hora da estrela (1977), de Clarice Lispector, teve o objetivo de aproximar os alunos da prática da leitura. Assim, a leitura literária, a mediação de leitura, a interação com a biblioteca escolar, a produção do portfólio de leitura e a didática de literatura são os principais pontos de interesse deste artigo. Para tanto, dialogaremos, principalmente, com Colomer (2007), Petit (2008, 2009, 2013), Jauss (1994), Rouxel (2013) e Rezende (2013). A leitura literária, neste caso, resultou na abertura para novas possibilidades de ensino e aprendizagem e provocou nos estudantes maior autonomia para se expressarem, emitirem opiniões a respeito das leituras, ou seja, trata-se de um momento em que eles se reconheciam como leitores de literatura.

Aby Warburg, a função rememorativa das imagens e o tempo: relatos e análises de Didi-Huberman acerca da sobrevivência das imagens
Authors: Santos Camila Geracelly Xavier Rodrigues dos
Published: July 2019

O presente estudo apresentará um ensaio sobre Aby Warburg, baseado no livro “A sobrevivência das Imagens” de Didi-Huberman, cujo texto se configura como chave hermenêutica para o entendimento do processo de montagem de Warburg, tentando estabelecer conexões entre sua vida, sua patologia e sua obra, com ênfase no processo de criação do Atlas Mnemosyne, seu último trabalho, entendido como incompleto, pois morre durante seu desenvolvimento, mas no que poderemos observar durante o desenvolvimento do texto, essa incompletude foi parte significante de todo o seu trajeto de deslocamento do olhar do sentido e do tempo na tentativa de encontrar sob os rastros arqueológicos as rupturas e entender a força de retorno das formas e imagens através do tempo e da cultura.Palavras-chave: Aby Warburg.

Aprendendo a ser “homem”: uma análise sobre o processo de produção/reprodução da referência heteronormativa de masculinidade
Authors: Bogéa Arthur Furtado
Published: July 2019

Este artigo objetiva fazer uma análise de como os discursos produzem, reproduzem e legitimam a referência heteronormativa de masculinidade. Compreende-se o gênero como construção social discursiva, produzido no processo histórico-político de constituição da sociedade e constrói as suas identidades a partir de um caráter binário. Foram realizadas análises do conteúdo de entrevistas e estudos bibliográficos sobre como ocorre à mediação da referência normativa de masculinidade na sociedade. Conclui-se que as identidades de gênero são (re)produzidas discursivamente dentro de contextos específicos e que a referência heteronormativa de masculinidade se (re)produz a partir de um processo de naturalização dos significados de gênero.Palavras-chave: Masculinidade. Heteronormatividade. Gênero. Discurso. Identidade.
Interacionismo sociodiscursivo e capacidades de linguagem: por uma pedagogia de gêneros aplicada ao ensino da leitura e da escrita
Authors: Lima Francisco Renato
Published: July 2019

Opta-se, neste texto, por uma discussão, sobre o ensino da leitura e da escrita na escola básica. A reflexão constrói-se a partir de uma pesquisa bibliográfica e exploratória, de abordagem qualitativa e dialógica, tendo como base, os conhecimentos da Linguística Aplicada (LA), associado às bases teóricas da Linguística Textual (LT), no que concerne a visão sobre gêneros discursivos, de Bakhtin (2009 [1929]; 2011 [1979]), ao propor uma concepção dialógica da linguagem, sustentáculo teórico que oferece a Bronckart (2012), condições para o desenvolvimento do Interacionismo Sociodiscursivo (ISD). Neste estudo reflete-se sobre a relevância desse fundamento teórico que reconhece e valoriza as capacidades de linguagem dos alunos, no processo de produção dos gêneros textuais (orais ou escritos) em uma situação comunicativa. Articulado a esse modelo, a pedagogia de gêneros, proposta pela Escola de Sydney, considera que a aprendizagem se dá em ciclos e neles, os gêneros assumem uma funcionalidade didática.Palavras-chave: Interacionismo Sociodiscursivo.

Como interpretar a mídia? As contribuições de Douglas Kellner e a Pedagogia Crítica da Mídia
Authors: Reisdoerfer Hiago M.
Published: July 2019

O artigo traça um guia para a utilização dos pressupostos teórico-metodológicos da Pedagogia Crítica da Mídia, de Douglas Kellner. O estudo é pautado nas reflexões do autor a respeito do agendamento ideológico dominante através do discurso presente nos produtos culturais com ênfase no discurso midiático apresentado por veículos de comunicação. Pretende-se, portanto, descrever e compreender a dinâmica de aplicabilidade da teoria, da mesma forma que se faz uma apresentação sobre suas categorias e consequente definição. Desta forma, a pesquisa se propõe a ser uma alternativa para tonificar o receptor, mostrando uma forma de ler e interpretar todo e qualquer discurso proveniente da mídia em geral, subsidiando uma maneira de separar os elementos puramente de manutenção ideológica e propagandísticos do que realmente representa um conteúdo válido e informativo. Delineia-se, por fim, uma solução para a alienação eminente provocada por tal discurso, principalmente em um período de Fake News e Miscommunication.Palavras-chave: Comunicação, Sociedade.

O objetivo deste trabalho é analisar os critérios de noticiabilidade utilizados pelos jornalistas Mauro Beting, Paulo Vinicius Coelho (PVC) e Juca Kfouri em seus Blogs durante a cobertura da Copa do Mundo da Rússia. Este trabalho utiliza-se de pesquisa bibliográfica para detalhar um breve histórico de cada um dos jornalistas cujos blogs cobriram a Copa do Mundo da Rússia, além do referencial teórico que trata do jornalismo esportivo. Todos os 242 textos publicados nos blogs pelos três cronistas no período da Copa do Mundo de 2018 foram analisados. São 90 de Mauro Beting, 80 de PVC e 72 de Juca Kfouri. Conclui-se que o jornalista em seu blog tem liberdade para escrever o que ele considera mais interessante do evento baseado em suas decisões. Constata-se, também, que nem todas as notas dos três jornalistas sobre a Copa do Mundo eram relevantes para serem publicadas. Apesar dos jogos considerados grandes possuírem maior destaque, as seleções menores também têm espaço.Palavras-chave: Noticiabilidade. Copa do Mundo. Juca Kfouri. Paulo Vinícius Coelho. Mauro Beting.
