O Sétimo Selo, de Ingmar Bergman, e as bases metafísicas da ciência moderna
Authors: Barreto Márcio
Published: June 2018

Explorando as potencialidades do cinema para dar a ver aquilo que excede a representação na tela e o próprio campo perceptivo do espectador, o filme O Sétimo Selo, de Ingmar Bergman, é aqui tomado como fio condutor das articulações entre as bases metafísicas da ciência moderna e a construção da oposição entre cultura e civilização. Outros filmes pontuam a análise que parte do triunfo da teoria gravitacional de Isaac Newton em direção ao largo espectro percepções visuais sobre a cultura ocidental oferecido por O Setimo Selo, do Gênesis ao Apocalipse, da aurora da ciência moderna à bomba atômica.

Published: June 2018

Este trabalho apresenta uma contribuição aos aspectos da climatologia dinâmica da Amazônia oriental, baseado na análise observacional das séries históricas de 40 anos (1975 a 2014) dos dados de precipitação para 30 estações meteorológicas dos estados do Pará, Maranhão e Tocantins. Os resultados mostraram que os padrões climatológicos de precipitação nos regimes chuvoso (janeiro a maio) e seco (julho a novembro) apresentam variabilidade espacial pronunciada, com características climáticas diferenciadas (intensidade e disposição geográfica dos máximos e mínimos pluviométricos) entre os dois regimes sazonais. Os dados de precipitação do satélite TRMM indicaram que a ZCIT e a ZCAS são os principais sistemas meteorológicos do regime chuvoso, enquanto que os aglomerados convectivos, linhas de instabilidade e influências das bandas frontais posicionadas no nordeste brasileiro são os principais sistemas que explicam a distribuição pluviométrica do regime seco. A análise de tendências usando o teste de Mann-Kendall para o regime chuvoso demonstrou sinais de aumento sistemático de precipitação particularmente no oeste, centro e nordeste do Pará e norte do Tocantins. Para o regime seco, há sinais de tendências positivas significantes no oeste/sudeste do Pará, contudo ressaltam-se os padrões de neutralidade (sem tendências) em grande parte do Maranhão e alguns setores do norte/nordeste do Pará.
IMPACTO DO AUMENTO DA CONCENTRAÇÃO ATMOSFÉRICA DE CO2 NO BALANÇO HÍDRICO CLIMATOLÓGICO DO CERRADO
Authors: Jesus Tammy Caroline Lima de , Senna Mônica Carneiro Alves , Cataldi Marcio , Paiva Célia Maria , Franz Barbara
Published: June 2018

Este trabalho avaliou os impactos que o aumento da concentração atmosférica de CO2 pode provocar no balanço hídrico do Cerrado, utilizando simulações feitas pelo modelo CCM3-IBIS. Foram avaliadas as condições climáticas atuais e um cenário climático futuro através da simulação controle da região e uma simulação com concentração atmosférica de CO2 elevada (cenário pessimista do IPCC). Analisando-se o Balanço Hídrico Climatológico (BHC) do Cerrado destes dois cenários, conclui-se que a deficiência hídrica da simulação com CO2 elevado (59,5 mm) é superior a da simulação controle (47,9 mm). Isto acontece devido ao aumento de temperatura do ar durante o período seco no cenário de CO2 elevado. Entretanto, o excedente hídrico da simulação com CO2 elevado (388,1 mm) também é superior ao da simulação controle (323,4 mm), pois os totais de precipitação foram maiores considerando o CO2 elevado. A deficiência hídrica no Cerrado concentra-se durante os meses de abril a setembro, que correspondem ao período seco da região. O período de excedente hídrico ocorre nos meses de novembro a março. Portanto, o BHC dos dois cenários mostra que o impacto do aumento do CO2 atmosférico varia conforme o total de precipitação da estação considerada. Na estação chuvosa o cenário de mudança climática aumenta o excedente hídrico no solo, porém durante a estação seca, ocorre um aumento de deficiência hídrica.
Being Brains
Authors: Vidal Fernando , Ortega Francisco
Published: June 2018

This book offers a critical exploration of the influential and pervasive belief that “we are our brains” (and that therefore he neurosciences will provide the key to all human phenomena). Since the 1990s, “neurocentrism” has become widespread in most Western and many non-Western societies. Advances, especially in neuroimaging, decisively bolstered it and helped justify increased funding for the brain sciences. Such a belief permeates many other contexts beyond basic research. Major national health agencies consider that “mental” illnesses are “brain disorders.” People diagnosed with some of those disorders advocate “neurodiversity” rights. In the human sciences, subspecialties such as neuroanthropology, neuroaesthetics, neuroeducation, neurohistory, neurolaw, neurosociology or neurotheology quickly professionalized. Dubious businesses, aimed for example at building neuroimaging lie detectors, selling (“neuromarketing”), or promoting wellbeing thanks to regimens said to target the brain (“neurobics”), became successful. The media has showered attention on all things “neuro,” and novels and films rehearsed the challenges of seeing persons as “cerebral subjects.” Skeptics have reacted to the “neurohype,” and spoken of neuromythology, neurotrash, neuromania or neuromadness. The neurocentric view of the human is not hegemonic or monolithic, but embodies a powerful ideology that is at the heart of some of today’s most important philosophical, ethical, scientific and political debates. Why We Are Our Brains critically explores the internal logic of such ideology, its genealogy, and its main contemporary incarnations.
Mind-Wave Controlled Robot: An Arduino Robot Simulating the Wheelchair for Paralyzed Patients
Authors: Cheng Chi Hang , Li Shuai , Kadry Seifedine
Published: June 2018

This project attempts to implement an Arduino robot to simulate a brainwave-controlled wheelchair for paralyzed patients with an improved controlling method. The robot should be able to move freely in anywhere under the control of the user and it is not required to predefine any map or path. An accurate and natural controlling method is provided, and the user can stop the robot any time immediately to avoid risks or danger. This project is using a low-cost and a brainwave-reading headset which has only a single lead electrode (Neurosky mind wave headset) to collect the EEG signal. BCI will be developed by sending the EEG signal to the Arduino Mega and control the movement of the robot. This project used the eye blinking as the robot controlling method as the eye blinking will cause a significant pulse in the EEG signal. By using the neural network to classify the blinking signal and the noise, the user can send the command to control the robot by blinking twice in a short period of time. The robot will be evaluated by driving in different places to test whether it can follow the expected path, avoid the obstacles, and stop in a specific position.
Technical Efficiency and Technical Change in Africa: The Role of Money from the Diasporas
Authors: O. Dzeha Gloria Clarissa , Abor Joshua Yindenaba , Turkson Festus Ebo , Agbloyor Elikplimi Komla
Published: June 2018

Based on evidence from the literature that the relationship between remittances and total factor productivity (TFP) is inconclusive, we employ the non-parametric Malmquist productivity index - Data Envelope Analysis to decompose total factor productivity (TFP) into technical change and technical efficiency and further investigate the effect of remittances on the technical change and technical efficiency. We employ the Seemingly Unrelated Regression estimation (SUR) technique in a panel of twenty-three African remittance recipient countries across a twenty-three-year period (1990-2013). We show that remittances received by households have a positive and significant impact on technical efficiency but no significant on technical change (innovativeness). We further show that remittances received by skilled labour is significant to technical efficiency but has a lowering effect on technical efficiency.

Published: June 2018

Senegal is in a very favourable geographical position for sea fishing. Its coast has an upwelling favouring a good development of phytoplankton very appreciated by the various fish families that populate its Exclusive Economic Zone (EEZ). The little pelagic fish make up the majority of landings. The dynamics of this family of resources is very complex while its perfect mastery is essential for a fishing well controlled maritime. The mathematical models that exist in the literature have not address the different issues related to maritime fisheries and climate change in the Senegalese fishing areas. The linear programming model in integer numbers has been developed after calculation of equilibrium biomass, catches at equilibrium catchability by the application of Schaefer and Freon models in the  Senegalese Economic Exclusive Zone. Two proposals have been developed to better explain the tools used in the writing of the mathematical model. The simulation results were led to the design of a linear integer Program (PLNE). The objective is to maximize the biomass of this family of fish resources on the Petite C\^ote, Grande C\^ote and Cape Verde depending on samples and climate change. In the application of the model, real data made it possible to test the Linear program in integer numbers obtained. This optimization study allowed us to find an effective way to maximize recruitment within this resource family. This consists in setting up several less expensive marine refuges to build in the fishing zones targeted by the study. The simulation computer program of the model is presented in the appendix.
Double Hopf Bifurcation of a Hematopoietic System with State Feedback Control
Authors: Ma Suqi
Published: June 2018

The dynamics of a system composed of hematopoietic stem cells and its relationship with neutrophils is ubiquitous due to periodic oscillating behavior induce cyclical neutropenia. Underlying the methodology of state feedback control with two time delays, double Hopf bifurcation occurs as varying time delay to reach its threshold value. By applying center manifold theory, the analytical analysis of system exposed the different dynamical feature in the classified regimes near double Hopf point. The novel dynamics as periodical solution and quasi-periodical attractor coexistence phenomena are explored and verified  by numerical simulation.
Los reportajes fotográficos en la prensa gráfica como instrumento de propaganda y divulgación del escultismo al sur de Brasil y en España en las primeras décadas del siglo XX
Authors: Martiarena de Oliveira Maria Augusta , Sureda García Bernat
Published: June 2018

En este artículo se estudia el discurso propagandístico que la prensa ilustrada nos ofrece de los boy scouts en el sur del Brasil y en España en las primeras décadas del siglo XX. Para el estudio nos hemos basado en las fotografías publicadas en las revistas de la época. En el artículo se demuestra como mediante las fotografías, tanto en Brasil como en España, desde las instancias del poder, se ofrece una reinterpretación del método creado por el militar británico Robert Baden-Powell, con el objetivo de dar a los jóvenes formación patriótica mediante la disciplina y el orden inculcando sentimientos favorables al militarismo. La Primera Guerra mundial, la postguerra y la crisis social y económica de aquellos años crearon el contexto necesario para una exaltación patriótica que encontró en el método scout una forma de adoctrinamiento y de formación militarista de la juventud. Las imágenes publicadas de los grupos de boy scouts, que se organizan en ambos países poco después de la creación del método en Inglaterra, muestran habitualmente su participación en actividades que implican subordinación al poder y rigurosa disciplina. Por el contrario, se encuentran pocas fotografías que muestren exclusivamente la vertiente lúdica y de educación activa que podía comportar la aplicación del método
La Escuela Nueva en Imágenes: Fotografía y Propaganda en The New Era (1920-1939)
Authors: Braster Sjaak , Pozo Andres Maria del Mar
Published: June 2018

En este artículo se aborda la labor de propaganda sobre el movimiento de la EscuelaNuevaque realizó The New Era, la revista en lengua inglesa que fue pionera, pues comenzó a publicarse en 1920, y también la primera que se erigió en órgano de expresión de la New Education Fellowship, la organización que aglutinó a los educadores de todo el mundo que compartían las ideas innovadoras del movimiento.Esta labor de propaganda se ha estudiado a partir de las imágenes que la revista publicó entre 1920 y 1939. Através de una metodología que combina el análisis de contenido y la grounded theory identificamos una serie de categorías que relacionamos con los grandes ideales dela Escuela Nueva. Consideramos, como punto de partida, que aquellas ideas y prácticas escolares que la revista visibilizó más —es decir, de las que publicó más imágenes— fueron aquellas con las que pretendía construir en la opinión pública un imaginario dela Escuela Nueva.Las seis ideas en torno a las que hemos organizado el discurso visual construido por esta revista son: coeducación, actividad, libertad, contacto con la naturaleza, paidocentrismo, e individualización vs socialización. De cada una de ellas hemos cuantificado el número de imágenes que se publicaron, diferenciadas por países y por períodos temporales. A partir del análisis cuantitativo, hemos tratado de explicar las pautas generales y los rasgos excepcionales, para concluir presentando las características más destacables del discurso iconográfico sobre la Nueva Educación que construyó y divulgó The New Era.

Published: June 2018

The categorical approach of personality disorders (PD) has given way to a dimensional paradigm. Within this, the Five-factor model (FFM) proposes theoretical hypotheses describing personality pathologies and PD empirical prototypes based on the DSM (DSM-PD). Moreover, a methodology to score DSM-PD using the NEO PI-R facets was developed. In this ex post-facto study FFM-PD count norms were developed using data from the NEO PI-R Spanish adaptation. Furthermore, the diagnostic agreement with the IPDE and validity of FFM-PD counts was analyzed in a clinical (n = 222) and non-clinical sample (n = 742). Based on NEO PI-R scores, we presented Spanish FFM-PD normative data. FFM-PD benchmarks were highly likely to be exceeded if subjects were classified as a subclinical case in the DSM-PD. Convergent correlations of FFM-PD counts with their equivalent subclinical cases of DSM-PD were statistically significant and outperformed any divergent correlation as well as the average divergent correlations in all FFM-PD. The use of a count technique based on NEO PI-R facets and Spanish FFM-PD normative data facilitate PD understanding and interpretation in various applied psychology fields.
Low levels of morning salivary α-amylase activity predict higher number of depressive symptoms in a community sample of children
Authors: Maldonado Montero Enrique Francisco , Fernández Martín María Eugenia , Trianes Torres María Victoria , Ortiz García Carmen , Engüix Alfredo , Nislin Mari
Published: June 2018

Models of the etiology of depressive disorders suggest that the onset of a depressive episode is the result of a complex phenomenon based on the interaction between genetic background, critical environmental factors such as life stressors and traumatic events, and the effects of neuroendocrine changes associated with the stress response. Numerous studies have highlighted the usefulness of morning cortisol (C) as a potential predictor of depressive episodes. The aim of this study was to compare the effectiveness of C, salivary alpha-amylase (sAA) activity/output, and the sAA/C ratio in predicting depressive symptoms in a community sample of 99 children aged 8-11 years old. Two saliva samples were obtained in the morning on two different school days. Teachers described their pupils' behavior by using the internalizing problems scales of the Teacher’s Report Form (TRF) questionnaire. Our results indicate that, regardless of gender, the best predictor of depressive/withdrawal scores and overall internalizing scores on the TRF was lower mean morning levels of sAA activity. Hence, sAA could be proposed as a biological marker for the risk of developing a first episode of depressive illness in child samples. 
Mindfulness and psychotic experiences in college students

Published: June 2018

The study of the relation between psychotic experiences and mindfulness in the general population is linked to research into factors of risk and protection against the development of a psychotic disorder. This study looks into the presence of psychotic experiences in a sample of university students and whether there is any variation according to gender. It also analyzes the predictive and discriminant relation of mindfulness with these experiences. The sample consisted of 526 university students (72.8% women) with a mean age of 21.39 years (SD = 3.53). The results showed the presence of psychotic experiences with differing levels of intensity, with variations according to gender, and an inverse relationship between mindfulness and psychotic experiences. Results indicated that students with high scores in psychotic experiences had lower scores in mindfulness. Our findings imply that mindfulness may be a factor of protection against psychotic experiences and its training may have a role to play in the development and implementation of preventive and early intervention programs in risk groups in the general and clinical population.

Published: June 2018

According to the interpersonal theory of suicide, thwarted belongingness and perceived burdensomeness are key elements in the development of suicidal ideation. The Interpersonal Needs Questionnaire (INQ) was developed to assess the degree of frustration of these two interpersonal needs related to suicidal ideation. This study aims to analyze the psychometrics properties of a Spanish adaptation of INQ-12 in fibromyalgia patients. Exploratory factor analysis (n = 180) and confirmatory factor analysis (n = 179) were performed in two randomly selected sub-samples. The first analysis leads to the elimination of two items, whereas the second one confirmed the fit of the proposed two-factor structure. The reliability estimated using the Cronbach´s alpha coefficient and the Spearman-Brown coefficient was adequate. To obtain further validity evidence based on the relationship with other variables three variables were used. Moreover, a control group (n = 99) was used to contrast the means of INQ scores as evidence of validity based on differential scores. These findings support the usefulness of the Spanish version of the INQ-10 for assessing the degree of frustration of these interpersonal needs in patients with fibromyalgia
Bidimensional Structure of the Orthorexia: Development and Initial Validation of a New Instrument
Authors: Barrada Juan Ramón , Roncero María
Published: June 2018

Orthorexia nervosa could be conceptualized as extreme or excessive preoccupation with eating food believed to be healthy. Up to now, there is no available instrument evaluating every aspect of orthorexia with sufficient psychometric guarantees. The objective of the present study was two-fold. First, to develop and validate a new questionnaire of orthorexia –the Teruel Orthorexia Scale– and, second, to analyze the association with other psychological constructs and disorders theoretically related to orthorexia nervosa: eating disorder symptoms, obsessive-compulsive disorder symptoms, negative affect, and perfectionism. Participants were 942 mainly university students who completed a battery of online questionnaires. Starting with an initial item bank of 31 items, we proposed a bidimensional test of orthorexia. This final version, with 17 items, encompassed two related, although differentiable (r = .43), aspects of orthorexia. First, Orthorectic Efforts, which evaluates the “healthy” preoccupation with diet, which is independent of psychopathology, and even inversely associated with it. Second, Orthorectic Concerns, which assesses the negative social and emotional impact of trying to achieve a rigid way of eating. This dimension represents a pathological preoccupation with a healthy diet. This study presents a new instrument that offers promising possibilities in the study of orthorexia.
Utilisation problématique d’Internet et des jeux vidéo chez des étudiants en médecine

Published: June 2018

La dépendance à Internet et aux jeux vidéo aurait un impact sur les performances académiques et la santé mentale. Un autoquestionnaire en ligne a été proposé à tous les étudiants en médecine de première année de l’Université de Namur (Belgique). Il s’agissait de questions d’ordre sociodémographique, de l’échelle de stress perçu PSS 14 (Perceived Stress Scale), de l’Internet Addiction Test (IAT), du Problem Video Game Playing (PVP) et de l’échelle de dépression MADRS (Montgomery and Asberg Depression Rating Scale). Notre méthodologie ne nous permet pas d’identifier des facteurs causaux, mais bien de mettre en lumière certains facteurs d’intérêt dans une population d’étudiants qui sera soumise lors de ses études et de sa future profession à l’utilisation intensive de ces technologies.

Selon l’IAT, 1 % des étudiants présentent une dépendance à Internet et 24,4 % ont un usage problématique occasionnel. D’après le PVP, 11,4 % des étudiants jouant à des jeux vidéo sont des joueurs problématiques. Les données révèlent par ailleurs des scores significativement plus élevés d’usage problématique d’Internet et des jeux vidéo parmi les étudiants stressés, parmi les étudiants déprimés et parmi ceux ayant de mauvais résultats académiques. Nous attirons l’attention sur le débat nécessaire entre l’utilisation raisonnée et l’utilisation problématique des nouvelles technologies ainsi que sur la nécessité d’une prévention longitudinale dès l’entrée aux études.

Published: June 2018

The aim of this work is to evaluate the design of the subject ICT as a teaching resource in science and mathematics taught in the Bachelor's Degree in Primary Education of the Universitat de València, during the academic courses 2013-14 and 2014-15. The analysis is based on the works of the students and their responses to a questionnaire. The purpose of the subject is to train pre-service teachers in the STEM discipline to make them able to teach Science and Mathematics in an integrated way throughout the Information and Communication Technologies (ICT). The results show a high interest of the students in the subject, the design of activities and the cooperative work. However, some difficulties are identified related to the interdisciplinary teaching of science and mathematics in elementary courses. The application of ICT in the STEM teaching is an opportunity to develop the teaching competence.

Published: June 2018

In this paper we present an analysis on the perception of educational agents in relation to the selection, use and creation of digital teaching materials, as well as an analysis of the educational offer in various educational platforms. In the study different people related to the Valencian Community education system such as public administration representatives, publishing houses managers, families, teachers and students, have been interviewed. For the collection of the information, semi-structured, individual and group interviews were used, as well as a content analysis of a selection of institutional platforms, publishers and teacher associations. The results confirm the central importance of the teaching figure and its formation for the successful practice with digital teaching materials and the need to consider the diversity of approaches that the different agents involved maintain towards the progressive process of digitalization in educational centers.
Re-emergence of the leaf clip gesture during an alpha takeover affects variation in male chimpanzee loud calls
Authors: Kalan Ammie K. , Boesch Christophe
Published: June 2018

Loud calls are used by many species as long-distance signals for group defense, mate attraction, and inter- and intragroup spacing. Chimpanzee loud calls, or pant hoots, are used in a variety of contexts including group coordination and during male contests. Here, we observed an alpha male takeover in wild chimpanzees (Pan troglodytes verus) during which the leaf clipping gesture re-emerged after disappearing for almost two years in this community. Leaf clipping only occurred in males and was observed almost exclusively prior to pant hoot vocalizations, as has been observed in other chimpanzee communities of the Taï forest in Côte d’Ivoire. Consequently, we hypothesized that leaf clipping may be important for male-male competition by affecting variation in the acoustic properties of male chimpanzee loud calls. We therefore investigated whether pant hoots preceded by leaf clipping differed acoustically from those without, while also testing the influence of social context on pant hoot variation, namely male dominance rank and hierarchy instability, i.e., before, during and after the alpha takeover. We found that pant hoots preceded by leaf clipping were longer, contained more call elements and drum beats, and lower fundamental and peak frequencies. Moreover, during the alpha takeover pant hoots were shorter, contained fewer drum beats and higher fundamental frequencies. Additionally, pant hoot and aggression rates were also highest during the alpha takeover with leaf clipping more likely to occur on days when pant hooting rates were high. Overall social rank had limited effects on pant hoot variation. We suggest that elevated arousal and aggression during the alpha takeover triggered the re-emergence of leaf clipping and the associated acoustic changes in pant hoots. Further research should focus on the potential mechanisms by which leaf clipping is connected to variation in pant hoots and cross-population comparisons of the behaviour.
Study on the mechanism of SVOC adsorption onto airborne particles in indoor air
Authors: Kondo Kosuke , Kagi Naoki , Namiki Norikazu
Published: June 2018

Semi‐volatile organic compounds (SVOC), such as di‐2‐ethylhexyl phthalate (DEHP), not only cause chemical sensitivity but can also trigger asthma. SVOCs are adsorbed onto airborne particles as well as gas‐phase molecules in indoor air, owing to their low vapor pressure. Therefore, 3 models are suggested to evaluate partitioning between the gaseous and particulate phases using data from previous studies. In this study, the characteristics of each model were extracted, and the mechanisms of DEHP adsorption onto test airborne particles were investigated under controlled temperature, airborne test particle concentration, and air exchange rate conditions in a chamber. The total DEHP concentration increased from 1.6 to 25.6 μg/m3 as the chamber temperature increased from 15 to 35°C. However, the particulate DEHP ratio φ decreased with the increase in temperature. The high airborne particle concentration caused an increase in the particulate DEHP concentration. Moreover, the estimates based on the Junge model corresponded well with the results of these experiments, whereas the Mackay and Pankow models overestimated the values of φ compared to the results of these experiments. These results indicate that particulate surface concentration is related to the DEHP adsorption mechanism onto airborne particles.
Commingled Human Remains
Authors: Osterholtz Anna J.
Published: June 2018

This entry provides a brief definition of commingled human skeletal remains, broken into three different types based on how they were created: (1) long‐term usage assemblages (those used for multiple depositional episodes, typically across generations); (2) episodic assemblages (those used for single depositional events resulting from the deposition of multiple individuals at a single time in a single deposit); and (3) lab commingling (unintentional commingling of individuals that occurs during analysis and storage). Analytical methodology and the importance of baseline data are also discussed.

Ankle and foot radiographs and joint hypermobility data (Beighton score for joint hypermobility criteria) were available for 848 participants (from 2003 to 2010) in this cross‐sectional study. General joint hypermobility was defined as a Beighton score ≥4 (range 0–9); knee hypermobility was defined as hyperextension of at least 1 knee. Standing anteroposterior and lateral foot radiographs were read with standard atlases for Kellgren‐Lawrence grade, osteophytes, and joint space narrowing (JSN) at the tibiotalar joint, and for osteophytes and JSN to define OA at 5 foot joints. Ankle or foot symptoms were self‐reported. Separate person‐based logistic regression models were used to estimate associations of ankle and foot OA and symptom outcomes with hypermobility measures, adjusting for age, sex, race, body mass index, and history of ankle/foot injury.

Results

This sample cohort included 577 women (68%) and 280 African Americans (33%). The mean age of the participants was 71 years, with a mean body mass index of 31 kg/m2. The general joint hypermobility of the participants was 7% and knee hypermobility was 4%. Having a history of ankle injury was 11.5%, and foot injury was 3.8%. Although general joint hypermobility was not associated with ankle and foot outcomes, knee hypermobility was associated with ankle symptoms, foot symptoms, and talonavicular OA (adjusted odds ratios of 4.4, 2.4, and 3.0, respectively).

Conclusion

Knee joint hypermobility may be related to talonavicular OA and to ankle and foot symptoms.
Achieving Exceptional Tensile Properties and Improved Microstructural Stability in Nanocrystalline Ni Via Amorphous Interfacial Phase by Codepositing Al Nanoparticles

Published: June 2018

A thin amorphous interfacial phase within microstructure is one of the promising strategies for designing better nanostructured materials. Nickel and Ni–Al nanocomposites fabricated by pulsed electrodeposition are deformed in tension and selected samples are heated to elevated temperatures. Here, the authors report that a well‐dispersed Al nanoparticle, possessing a thin layer of amorphous oxide shell, reinforcement in nanocrystalline Ni matrix enhances tensile strength by ≈60% without losing ductility and also provides better microstructural stability due to existence of local microstructural gradient.

Direct photopatterning of indium zinc oxide (IZO) and zinc tin oxide (ZTO) semiconductors is realized using Schiff‐base complexes of indium, zinc, and tin(II) with methoxyiminopropionato ligands as precursors. These precursor complexes are stable under visible light, but they interestingly decompose in the UV region, thereby facilitating a site‐selective photopatterning and its subsequent conversion to the desired amorphous oxides. Thin film transistors (TFTs) with photopatterned IZO and ZTO layers exhibit high performance after post‐annealing at relatively low temperatures between 250 and 350 °C, with charge‐carrier mobilities (µsat) of 7.8 and 3.6 cm2 (V s)−1 for IZO and ZTO, respectively. The mechanism of the photodecomposition of the precursor films is studied by attenuated total reflectance–Infrared spectroscopy. Apart from the electrical characterization, the resultant UV‐patterned oxide thin films are characterized by transmission electron microscopy micrographs of focussed ion beam (FIB)‐prepared cross sections, atomic force microscopy, as well as Auger depth profiles. X‐ray photoelectron spectroscopy investigations elucidate the influence of surface hydroxylation on the TFT performance. The straightforward approach of facile precursor UV‐photopatterning demonstrates its potential feasibility as a low‐cost method toward integration of such solution–processed oxide films into large‐area electronics.

Published: June 2018

Organometal halide perovskite solar cells (PSCs) are brought to the forefront of research focus in photovoltaics field with a rapid efficiency rising over 22% in the past few years. Interface engineering with suitable hole‐transporting layer (HTL) and/or electron‐transporting layer (ETL) plays very important roles in controlling the charge carrier behavior in planar PSCs. Particularly, the utilization of doped charge‐transporting layers is regarded as an efficient route to further improve the device performance of the planar PSCs. In this review, first the fundamental roles of doped charge‐transporting layers are briefly introduced. Then, the review mainly summarizes the recent progress in the development of doped HTLs and ETLs. Finally, a prospective of promising applications of doped charge‐transporting layers in planar PSCs is proposed.

After over 30 years of development, colloidal quantum dots have now become mature luminescent materials in photonic and optoelectronic operations and start to hit the market. The emerging perovskite nanocrystals are expected to promote large‐scale commercialization due to their superior optical properties as well as low cost and easy fabrication. This progress report is focused on the developments of in situ fabricated perovskite nanocrystals with attractive features of excellent superior photoluminescence and electroluminescence performance, as well as the solution processability, easy integration, and scale‐up fabrication. These advantages make them suitable candidates as down‐shifting materials for photonics or emissive component for optoelectronics. Recently, the first television demons using composite films based on in situ fabricated perovskite nanocrystals were demonstrated at CES 2018 exhibition, and the performance of electroluminescence devices based on in situ fabricated perovskite nanocrystals is leading the study. It is believed that the in situ fabricated perovskite nanocrystrals will bring a revolution in the field of optical materials after further developments.

Reverse hybrid therapy, modified from the hybrid regimen by changing the sequence of drug administration, achieves a high eradication rate for Helicobacter pylori and is superior to standard triple therapy. Currently, the impacts of different proton pump inhibitors on the efficacy of this novel therapy remain unanswered. This study was conducted to compare the efficacies of esomeprazole‐ and pantoprazole‐based reverse hybrid therapies for H. pylori eradication. From August 2015 to May 2016, H. pylori‐infected patients receiving either a 14‐day esomeprazole‐ or a pantoprazole‐based reverse hybrid therapy (esomeprazole or pantoprazole 40 mg and amoxicillin 1 g twice‐daily for 14 days, plus clarithromycin 500 mg and metronidazole 500 mg twice‐daily for the initial seven days) for H. pylori eradication were included in the retrospective study. All the patients underwent a follow‐up endoscopy with a rapid urease test and histological examination or a urea breath test at eight weeks after the end of anti‐H. pylori therapy to assess H. pylori status. To determine the independent factors affecting the treatment response, 12 clinical and endoscopic parameters were analyzed by multivariate analysis. In all, 123 H. pylori‐infected outpatients were included for this study. Among them, 62 received the esomeprazole‐based regimen and 61 received the pantoprazole‐based regimen. Intention‐to‐treat (ITT) analysis demonstrated no differences in eradication rate between esomeprazole‐ and pantoprazole‐based groups (90% vs 97%; P = 0.273). Modified ITT (90% vs 98%) and per‐protocol analysis (92% vs 98%) yielded similar results (P = 0.115 and 0.116, respectively). Both groups had comparable frequencies of adverse events (16% vs 21%; P = 0.779) and drug compliance (98% and 93%; P = 0.207). The eradication rates were significantly related to increased body fat percentage (P = 0.002) and the presence of diabetes (P = 0.033). Multivariate analysis disclosed an increased body fat percentage (odds ratio: 0.072, 95% confidence interval: 0.008‐0.623), which was the only independent predictor of treatment failure. Esomeprazole‐ and pantoprazole‐based reverse hybrid regimens have comparable anti‐H. pylori efficacy and both achieve an eradication rate more than 90%. Increased body fat percentage is a clinical factor predicting eradication failure of reverse hybrid therapy.
