When art meets crisis: the Portuguese story and beyond
Authors: Silva Augusto Santos , Guerra Paula , Santos Helena 
Published: March 2019

The article focuses on how the Portuguese arts have dealt with the Portuguese crisis, in the years 2011-2014, when the country was subjected to a financial bailout. The approach is based on a cross-section analysis, considering the domains of literature, fine arts, visual arts and cinema, music and performing arts. It emphasizes three distinct and complementary ways through which the relation between arts and society was developed in these years. The first way is the directly political positioning of artists, through artistic works and performances. The second way is the presence of the crisis as a background of several artistic creations of this time. And the third way is the one by which the crisis projects a new light into consistent topics of the Portuguese artistic imagination, stressing the centrality of collective identity and self-reflexivity. The Portuguese case suggests how promising can be for the sociological explanation of social processes the consideration of their cultural and artistic dimensions.
O tempo de residência e de contacto com a criança após divórcio ou separação: experiências de mães e de pais
Authors: Marinho Sofia 
Published: March 2019

O artigo examina as práticas e os significados subjetivos que dividem o tempo parental e como estes moldam papéis parentais, identidades e a relação com a criança quer nas experiências de mães e pais separados, quer na aplicação da Lei do Divórcio N.º 61/2008. Com base num inquérito online, revela-se que a lei é resistida e manteve o uso do género para alocar tempo parental no regime de residência e contacto. Neste, as mães residentes vivem a relação entre a gratificação afetiva e identitária e a sobrecarga parental. Ao invés, os pais não residentes lidam com a privação parental e a submissão à paternidade tradicional. No regime de residência alternada abraça-se a partilha parental e os desafios da concertação educativa, nem sempre aceites na aplicação da Lei.
Trainee-teacher: A Second or a Secondary Teacher in the Classroom? Emotional Aspects of Teaching Practicum in the “Academia Class” Program
Authors: Nissim Yonit , Naifeld Edni 
Published: March 2019

This research focused on the practicum experience in the Academia Class program. This article puts a spotlight on the emotional aspects, thoughts, feelings and perceptions concerning co-teaching in this unique program. The research is a mixed-methods study (qualitative and quantitative).The research population included 125 teachers, 51 (40.8%) practicing trainer teachers, 36 (28.8%) trainee-teachers, 18 (14.4%) kindergarten trainer teachers and 20 (16%) early childhood trainee-teachers.
The research questions were: “Is the trainee-teacher a second or a secondary teacher in the class? Do the trainer-teachers and trainee-teachers have a common motivation to adopt co-teaching and what is that motivation? How do the trainer-teachers and trainee-teachers describe their feelings and emotions within the framework of the practicum in the Academia Class program, especially with regard to co-teaching?
The main findings indicate that the trainer-teachers in schools saw the trainee-teachers as a second teacher in the classroom already from the first day of their practicum (3.86), while the trainee kindergarten teachers were not seen as second kindergarten teachers (2.86) by their trainers. This difference was found to be significant. In contrast it was found that in early childhood education, the trainee-teachers reported that they felt they were an integral part of the kindergarten staff in a more significant manner - synergetic teaching (3.94) than did the trainee-teachers in the schools (3.03). Moreover, it was found that there was a gap between the way in which the trainee-teachers perceived themselves as second teachers in co-teaching (3.27) and the way in which they were perceived by the trainer-teachers (3.45) and kindergarten teachers (3.78) The trainee-teachers saw themselves as equal (over-evaluation) to the teachers/kindergarten teachers, in contrast to the perceptions of the trainer-teachers in schools and kindergartens.
From the qualitative analyses, we found several categories that were identified as meaningful: interpersonal interaction, suitable training and preparation, high-quality teachers/student-teachers, motivation and emotions expressed because of this unique experience. Content analysis of the reflective consideration of the program participants to this question indicated that subjective interpersonal interactions (trainee-trainer in schools and in kindergartens) produced various feelings. These findings echoed and complemented the findings from the quantitative part of the research. The main conclusion from the findings is that the trainee-teachers were seen as secondary trainee-teachers and not as second teachers. In contrast, in the kindergartens although the trainee-teachers were not portrayed as second teachers, over the year they felt a sense of equality with the kindergarten teacher and as full participants in the pedagogic work of the kindergarten teacher received a higher level of co-teaching.
Attitudes to School Teacher and Peers – Mixed Ethnicity Groups Compared to Majority and Minority Student Networks
Authors: Holfve-Sabel Mary-Anne 
Published: March 2019

Aims: The general aim of this study was to investigate students’ attitudes to school, teacher and peers in voluntarily-chosen networks with respect to ethnicity and gender.
Study Design: Self-reports on attitudes were collected from 12-year old students in 77 grade 6 classes in the city of Göteborg, Sweden. Social networks were made up of students who voluntarily and reciprocally chose each other to be with during breaks.
Place and Duration of Study: Sampling of all data autumn 2003. Work up of sociometric data 2016.
Methodology: Based on a previous two-level confirmatory factor analysis, three school factors and four relational factors were identified. Social network analysis of the choices was carried out using a Matlab program identifying reciprocal (bilateral) choices. Three categories of network were identified using the names of their members. Mixed ethnicity networks were compared to majority (Scandinavian), and minority networks (Non-Scandinavian). Members outside networks were labelled “Outsiders”.
Results: One out of five students was classified non-Scandinavian. Non-Scandinavian networks had high scoring for the categories “Interest in School” and “Working Atmosphere”. In Scandinavian networks, girls were more anxious at school and scored relationships to their classmates and the view of their peers significantly lower than the male students. Girls in this category also felt that disruption in the classroom was more common while the boys were, apparently, more tolerant of it. Within Mixed networks, gender differences were exclusively dependent on Non-Scandinavian students’ attitudes. Non-Scandinavian girls in the Mixed networks were surprisingly similar to their female Scandinavian peers. Individuals outside networks were overrepresented among Non-Scandinavians. They showed weaker relationships with classmates, had more problems with peers and were more anxious at school. Furthermore, they considered disruption during lessons to be common.
Conclusion: Promotion of a mixture of ethnicities appeared best for improving attitudes to school. Immigrant children were overrepresented in the Outsider group, and at risk of rejection.

The study examined the impact of thermal treatment on anatomical and mechanical properties Ricinodendron heudelotii wood. Wood samples were oven dried at 105°C and cooled in a desiccator to a constant weight before the thermal treatment. Heat treatment of wood was carried out in a Furnace at 120°C, 140°C and 160°C for 45 minutes and 90 minutes. The Density, Modulus of Elasticity (MOE), Modulus of Rupture (MOR), and the anatomical properties were assessed. The results for Density of Ricinodendron heudelotii wood showed decrease from 279 kg/m3 (120°C at 45 minutes) to 256 kg/m3 (160°C at 90 minutes) while that of control was 281 kg/m3 which was lower than the treated samples. The increase in temperature with time had effect of the color of wood as it changed from creamy white to dark brown. The image of untreated and treated samples showed no significant changes within and among treatment groups as there was no effect of treatment time and exposure on the samples.
The MOE of heat treated Ricinodendron heudelotii increased from 2064.84 N/mm2 (140°C for 45 minutes) to 2271.93 N/mm2 (160°C for 90 minutes) while MOR decreased from 40.56 N/mm2 (140°C for 90 minutes) to 33.53 N/mm2 (160°C for 90 minutes). The study revealed that the wood could be used in a light furniture as unnecessarily heavy wood is not important. Also, the study proved effective in improving the modulus of elasticity of the wood.

AbstractHigh‐output‐power electron‐beam (e‐beam) pumped deep ultraviolet (DUV) light sources, operating at 230–270 nm, are achieved by adjusting the well thickness of binary ultrathin GaN/AlN multiple quantum wells. These structures are fabricated on high‐quality thermally annealed AlN templates by metal‐organic chemical vapor deposition. Owing to the reduced dislocation density, large electron–hole overlap, and efficient carrier injection by e‐beam, the DUV light sources demonstrate high output powers of 24.8, 122.5, and 178.8 mW at central wavelengths of 232, 244, and 267 nm, respectively. Further growth optimization and employing an e‐gun with increased beam current lead to a record output power of ≈2.2 W at emission wavelength of ≈260 nm, the key wavelength for water sterilization. This work manifests the practical levels of high‐output‐power DUV light sources operated by using e‐beam pumping method.

AbstractTransition metal ion dissolution due to hydrofluoric acid attack is a long‐standing issue in the Mn‐based spinel cathode materials of lithium‐ion batteries (LIBs). Numerous strategies have been proposed to address this issue, but only a fragmentary solution has been established. In this study, reported is a seaweed‐extracted multitalented material, namely, agar, for high‐performance LIBs comprising Mn‐based cathode materials at a practical loading density (23.1 mg cm−2 for LiMn2O4 and 10.9 mg cm−2 for LiNi0.5Mn1.5O4, respectively). As a surface modifier, 3‐glycidoxypropyl trimethoxysilane (GPTMS) is employed to enable the agar to have different phase separation behaviors during the nonsolvent‐induced phase separation process, thus eventually leading to the fabrication of an outstanding separator membrane that features a well‐defined porous structure, superior mechanical robustness, high ionic conductivity, and good thermal stability. The GPTMS‐modified agar separator membrane coupled with a pure agar binder to the LiNi0.5Mn1.5O4/graphite full cell leads to exceptional improvement in electrochemical performance outperforming binders and separator membrane in current commercial products even at 55 °C; this improvement is due to beneficial features such as Mn2+ chelation and PF5 stabilizing capabilities. This study is believed to provide insights into the potential energy applications of natural seaweeds.

Published: March 2019

AbstractChronic hepatitis B with acute exacerbation carries a high risk of mortality even in the era of advanced antiviral agents. Derived from Glycyrrhiza glabra roots, glycyrrhizin is a natural compound possessing anti‐inflammatory and antioxidant properties and having a membrane‐stabilizing effect. The significant reductive effect of its aqueous solution, Stronger Neo‐Minophagen C (SNMC), on serum levels of transaminases has been previously demonstrated. Furthermore, it is effective in the treatment of subacute hepatic failure. In this prospective case series, we examined the efficacy of the combination treatment of glycyrrhizin and entecavir on acute‐on‐chronic hepatic failure in chronic hepatitis B patients. Every patient received a combination of oral entecavir and intravenous SNMC 100 mL (glycyrrhizin 200 mg) daily for 5 days. We evaluate the 3‐ and 6‐month survival rates, percentage of patients returning to liver compensation within 30 days, and the days of hospital stay. Ten patients were enrolled in this study. Before treatment, the mean alanine aminotransferase (ALT) and total bilirubin levels were 2101 ± 931 IU/L and 7.4 ± 2.2 mg/dL, respectively. The ALT level nearly halved after 2 days of treatment. The average hospital stay was 6.3 ± 1.3 days, and the 3‐ and 6‐month survival rate was 100%. A return to liver compensation within 30 days was achieved in eight patients (80%). This preliminary study demonstrates the safety and efficacy of combination treatment of SNMC and entecavir for about 5 days, which may result in shorter hospital stays and good survival of chronic hepatitis B patients with acute‐on‐chronic hepatic failure.

Published: March 2019

BackgroundSeptic shock is a subset of sepsis accompanied by profound circulatory and cellular metabolism abnormalities. Although veno‐arterial extracorporeal membrane oxygenation (VA‐ECMO) can provide temporary cardiac support to improve organ perfusion, hemodynamic support by VA‐ECMO for adult patients with septic shock is still controversial.Case presentationA 67‐year‐old man was transferred to our hospital with generalized weakness. He suffered septic shock refractory to vasopressors and inotropes, and his cardiac function deteriorated rapidly. Because of concern for sudden cardiac arrest, he was placed on VA‐ECMO 9 h after his arrival. Blood culture was positive for Aeromonas hydrophila. He was weaned off VA‐ECMO on day 7 and was discharged without any sequelae on day 30.ConclusionVeno‐arterial extracorporeal membrane oxygenation is a viable treatment option for adult patients with refractory septic shock accompanied by cardiac dysfunction. Further research is warranted to identify the candidates for support by VA‐ECMO in a timely fashion.
New diorganotin(IV) complexes of Schiff base derived from 4‐amino‐3‐hydrazino‐5‐mercapto‐4H‐1,2,4‐triazole: Synthesis, structural characterization, density functional theory studies, atoms‐in‐molecules analysis and antifungal activity

Published: March 2019

New diorganotin(IV) complexes of a Schiff base (HL) having general formula R2Sn(L)Cl (where L is the monoanion of HL and R = n‐Bu or Ph) have been synthesized and characterized using elemental analysis, infrared, NMR (1H, 13C, 119Sn) and UV–visible spectroscopies and mass spectrometry. These investigations suggest that in these 1:1 monomeric derivatives the Schiff base ligand acts in a monoanionic bidentate manner coordinating through the Ophenolic and Nazomethine, with proposed distorted trigonal bipyramidal geometry around tin with Ophenolic and two organic groups in the equatorial plane and the Nazomethine and the third organic group in axial positions. The proposed structures have been validated by density functional theory (DFT)‐based quantum chemical calculations at the B3LYP/6‐31G(d,p)/Def2‐SVP (Sn) level of theory. The simulated UV–visible spectrum was obtained with the time‐dependent DFT method in the gas phase and in the solvent field with the integral equation formalism–polarizable continuum model. A comparative analysis of the experimental vibrational frequencies and simulated harmonic frequencies indicates a good correlation between them. An insight into the intramolecular bonding and interactions among bonds in organotin(IV) complexes of HL was obtained by means of natural bond orbital analysis. The topological and energetic properties of the electron density distribution for the tin–ligand interaction in R2Sn(L)Cl have been theoretically calculated at the bonds around the central tin atom in terms of atoms‐in‐molecules theory. The R2Sn(L)Cl complexes were screened for their in vitro antifungal activity against chosen fungal strains.

Two mononuclear ruthenium complexes (1 and 2) with aroyl/acylthiourea as an ancillary ligand of type, [(η6‐p‐cymene)RuCl(L‐N,S)], where [L1 = 2,4‐dichloro‐N‐(o‐tolylcarbamothioyl)benzamide] and L2 = N‐(phenylcarbamothioyl)cyclohexanecarboxamide] were synthesized and well characterized. The single crystal X‐ray diffraction studies revealed the coordination mode and the geometry of the complexes. The two complexes adopted general piano‐stool (three‐legged) geometry with a novel coordination mode of aroyl/acylthiourea through amide N (anionic) and thiocarbonyl S (neutral). This type of monobasic bidentate coordination of the aroyl/acylthiourea ligand was witnessed the first time around the metal ion. The coordination of the complexes was well explained through geometric parameters and frontier molecular orbital parameter values computed at the B3LYP/SDD level. The synthesized complexes were also screened for their antibacterial, antifungal, antioxidant and in vitro antiproliferative activities. Complexes exhibited good antimicrobial agents against various pathogens. The antioxidant activity of the complex 2 has shown most potent activity with IC50 value of 48.55 ± 1.7 μM compared to the reference drug. In addition, the in vitro antiproliferative activity of the complex 2 showed excellent activity against HepG‐2 cell line with the IC50 value of 24.30 ± 1.20 μM which is close to Doxorubicin standard drug.
The existence and exponential stability of periodic solution for impulsive delay differential equations
Authors: Lin Yusen , Pu Xiaoqin , Li Dingshi 
Published: March 2019

AbstractIn this work, we first establish a new generalized Halanay inequality with impulses, which have two advantages: one is that impulses can be applied to stabilize the unstable continuous system, the other is that the requirements on the coefficients of inequality are more relaxed than those in previous works. Then, by using the inequality and Banach fixed point theorem, we will obtain some sufficient conditions ensuring the existence and exponential stability of periodic solution for impulsive delay differential equations. The sufficient conditions are easily checked in practice and have a wider adaptive range. Some examples are given to illustrate our results.
Double trapper technique: A novel technique to facilitate retrograde wire externalization in aorto‐ostial chronic total occlusion intervention without using snare
Authors: Chan Chi Yuen , Chan Yu Ho 
Published: March 2019

AbstractChronic total occlusion (CTO) remains a technical challenge for the interventional cardiologists. The application of the retrograde approach has dramatically improved success rates of CTO PCI. However, retrograde wire externalization could be very difficult especially when the antegrade guiding catheter cannot sit into the coronary ostium stably. We report a novel technique to facilitate retrograde wire externalization in aorto‐ostial chronic total occlusion intervention without using snare.

AbstractZirconium oxide has been proposed as an alternative to carbon supports due to its high electrochemical stability at high electrode potential values. However, its low electrical conductivity has limited its use. In this work, we successfully overcome this issue by synthesizing Pt electrocatalysts directly on ZrO2 supports. The ZrO2 supports were obtained through a sol‐gel method at 350 °C (ZrO2‐350) and 500 °C (ZrO2‐500) calcination temperatures, obtaining surface areas of 82 and 92 m2 g−1 and crystalline phases corresponding to the tetragonal and mixture of tetragonal and monoclinic phases, respectively. Pt nanoparticles synthesized directly on ZrO2 had particle sizes of 3.0±0.3 nm and 6.0±0.8 nm for Pt/ZrO2‐350 and Pt/ZrO2‐500, respectively. Pt/ZrO2‐350 and Pt/ZrO2‐500 presented similar onset potentials (−0.34 V and −0.33 V) and current densities (249.3 mA mg−1 and 255.8 mA mg−1) than a commercial Pt/C (−0.39 V, 277.5 mA mg−1) during the electro‐oxidation of 2 M methanol in alkaline medium. Regarding catalyst stability, Pt/ZrO2‐500 kept 96 % of its initial current after 500 cycles, while Pt/C maintained 49 % of its initial current.
