Authors: Zhu Zuoliang , Hou Lei , Zhang Xinru , Liu Jiaquan , Sun Xingshen , Xiong Yifan 
Published: December 2023

The rheological properties of emulsions are complex, leading to serious flow assurance issues that affect the economical and safe operation of pipelines. It has been reported that applying magnetic treatment technology can effectively improve the flowability of waxy crude oil. The study aims to investigate the influence of magnetic treatment on the viscosity of waxy crude oil emulsions. A dynamic electromagnetic treatment device was designed. The dynamic magnetic treatment experiments of waxy crude oil emulsion were carried out to explore the effects of magnetic field intensity and magnetic field frequency on the viscosity change of waxy crude oil emulsion. Research results show that with four different magnetic field frequencies, the viscosity of the emulsion decreases initially and then increases with the increase in magnetic field intensity. The variation law of emulsion viscosity with magnetic field intensity is related to the magnetic field frequency. When the magnetic field frequency is 100 Hz, the highest and lowest viscosity variation rates are 7.91% and -7.36%, respectively, which occur at the magnetic field strength of 110 mT and 30 mT, respectively. It is believed that applying a higher field strength electromagnetic field to the emulsion is beneficial for viscosity reduction. The research findings can provide guidance for the further study of the viscosity reduction of waxy crude oil emulsion magnetic treatment technology.

Authors: Zhang Yuan 
Published: December 2023

In this paper, the mechanical, dry shrinkage and frost resistance performance of cement stabilized aggregate materials were investigated. Furthermore, the nonlinear analysis between dry shrinkage strain and frost resistance performance was conducted. The results showed that the mechanical performance of cement stabilized aggregate with different cement content showed a linear improving relationship. A higher cement content owns a correspondingly better mechanical performance. With the different moisture content, the dry shrinkage and frost resistance performance of cement stabilized aggregate material showed a similar improving and deteriorating trend. With the increasing moisture content, the dry shrinkage strain and dry shrinkage coefficient were improved and reached to the optimum values, and then started to deteriorate. The optimum dry shrinkage and frost resistance performance were obtained with 6.0% moisture content. The nonlinear relationship between dry shrinkage strain and frost resistance coefficient was gained and the correspondingly optimum dry shrinkage strain and frost resistance was discerned, i.e. 94.3×10-6 and 47.6, respectively. The moisture content significantly influence the pore parameters of prepared samples, whose trend followed those of dry shrinkage and frost resistance performance. The pore size distribution of these composites shifted toward smaller pore size scope with a proper moisture content. In addition, scanning electron micrographs (SEM) showed that the denser microstructure of prepared cement stabilized aggregate materials.

As an important performance indicator for measuring product quality and safety, vehicle corrosion resistance has always been of great concern to industry enterprises and consumers. In this paper, we collect, processed and analysed exterior corrosion data from a total of 54 in-use vehicles (the vehicle that has been licensed and put into service) of nine models with high ownership in the coastal region of North China. Through the evaluation model of automobile corrosion resistance performance, data mining analysis was conducted on five key areas and the whole vehicle with different brands and ages (3-year and 6-year vehicles), key areas including exterior body, passenger compartment, luggage compartment, engine compartment, and chassis. It was found that the chassis and engine compartment of each vehicle model were severely corroded, with the corrosion surface of some chassis parts reaching 100%. The luggage compartment and exterior body were slightly corroded, and the luggage compartment parts of 8 models have not corroded after 3 years of use.

Published: December 2023

Seres humanos têm necessidade perene de encontrar respostas significativas para a sua vida: as respostas implicam a espiritualidade/religiosidade/religião e as experiências culturais. Nesse contexto objetiva-se discutir na perspectiva ético-fenomenológica a atuação pública das pessoas que detêm conhecimento teológico em vista de colaborar para a vida na sociedade plural do século XXI. A literatura escolhida para pensar crítico-reflexivamente a questão tem base fenomenológica, teológico-moral, e a perspectiva pública da Teologia. Observa-se que medo e culpabilidade estão ligados às “falsas imagens” de Deus; não são de poucos os prejuízos e as dificuldades causadas por esta equivocada experiência. Resulta que convém reconsiderar, em muitos casos, a vida moral a partir de um ethos profético, tornando mais crível e acolhedora a presença do Divino no mundo. Ou seja, requer sair da Academia e/ou dos Templos para estar junto à sociedade que convive em interculturalidade e inter-religiosidade.

Published: December 2023

Humans always communicate in their lives, because humans need communication to interact with other humans. The communication process has a lot of elements so that what is conveyed by the communicator can be conveyed clearly to the communicant. Intercultural communication is communication carried out by people who have different cultural backgrounds that have been adopted since ancient times until now. Communication occurs through verbal and non-verbal messages that occur among humans as social creatures supported by the surrounding environment. The purpose of this study is to examine the process of Speech Code adjustment in intercultural communication, especially those that occur in Javanese who interact with Betawi people in Bedahan village, Sawangan, Depok. The research method used in the study is a qualitative method with a qualitative descriptive approach and data collection techniques using observation, interview, and documentation techniques. The results of this study indicate that the cultural adaptation experienced by immigrants to indigenous people in Bedahan Sawangan Depok village tends to use adaptation in language code and cultural acculturation. Language codes that can be adapted are dialect language codes and gestures. While cross-cultural adaptation that develops in immigrant residents is acculturation adaptation where immigrants want to learn some of the host culture's behavior, beliefs and values without releasing their original cultural behavior, beliefs and values of the immigrant residents.

Regard sur des défis scolaires en contexte de diversité ethnoculturelle et perspectives de développement
Authors: Kharchi Zina , Koubeissy Rola 
Published: December 2023

Cet article explore certains défis auxquels fait face le personnel enseignant qui travaille dans un contexte de diversité et d’inclusion, et propose des perspectives de développement. Pour ce faire, nous avons mené une revue de littérature pour faire ressortir des thématiques, entre autres, celles autour desquelles s’articulent les recherches en éducation inclusive sous l’angle de la diversité ethnoculturelle. Ces thématiques ont ensuite permis de faire émerger trois catégories de défis, en contexte de diversité ethnoculturelle et d’inclusion : 1) des défis en lien avec la formation initiale et continue du personnel enseignant; 2) des défis en lien avec la mise en place des pratiques pédagogiques et des ressources; et 3) des défis en lien avec la collaboration avec les familles. Un aperçu général sur le concept de l’enseignement sert d’introduction aux trois sous-parties.
Maternal Migration Background and Mortality Among Infants Born Extremely Preterm
Authors: Vidiella-Martin Joaquim , Been Jasper V. 
Published: December 2023

ImportanceExtremely preterm infants require care provided in neonatal intensive care units (NICUs) to survive. In the Netherlands, a decision is made regarding active treatment between 24 weeks 0 days and 25 weeks 6 days after consultation with the parents.ObjectiveTo investigate the association between maternal migration background and admissions to NICUs and mortality within the first year among extremely preterm infants.Design, Setting, and ParticipantsThis cross-sectional study linked data of registered births in the Netherlands with household-level income tax records and municipality and mortality registers. Eligible participants were households with live births at 24 weeks 0 days to 25 weeks 6 days gestation between January 1, 2010, and December 31, 2017. Data linkage and analysis was performed from March 1, 2020, to June 30, 2023.ExposureMaternal migration background, defined as no migration background vs first- or second-generation migrant mother.Main Outcomes and MeasuresAdmissions to NICUs and mortality within the first week, month, and year of life. Logistic regressions were estimated adjusted for year of birth, maternal age, parity, household income, sex, gestational age, multiple births, and small for gestational age. NICU-specific fixed effects were also included.ResultsAmong 1405 live births (768 male [54.7%], 546 [38.9%] with maternal migration background), 1243 (88.5%) were admitted to the NICU; 490 of 546 infants (89.7%) born to mothers with a migration background vs 753 of 859 infants (87.7%) born to mothers with no migration background were admitted to NICU (fully adjusted RR, 1.03; 95% CI, 0.99-1.08). A total of 652 live-born infants (46.4%) died within the first year of life. In the fully adjusted model, infants born to mothers with a migration background had lower risk of mortality within the first week (RR, 0.81; 95% CI, 0.66-0.99), month (RR, 0.84; 95% CI, 0.72-0.97), and year of life (RR, 0.85; 95% CI, 0.75-0.96) compared with infants born to mothers with no migration background.ConclusionsIn this nationally representative cross-sectional study, infants born to mothers with a migration background at 24 weeks 0 days to 25 weeks 6 days of gestation in the Netherlands had lower risk of mortality within the first year of life than those born to mothers with no migration background, a result that was unlikely to be explained by mothers from different migration backgrounds attending different NICUs or differential preferences for active obstetric management across migration backgrounds. Further research is needed to understand the underlying mechanisms driving these disparities, including parental preferences for active care of extremely preterm infants.
Structural Tailoring the Phenylenediamine Isomers to Obtain 2D Dion–Jacobson Tin Perovskite Solar Cells with Record Efficiency

Published: December 2023

Abstract2D Dion–Jacobson (DJ) tin halide perovskite shows impressive stability by introducing diamine organic spacer. However, due to the dielectric confinement and uncontrollable crystallization process, 2D DJ perovskite usually exhibits large exciton binding energy and poor film quality, resulting in unfavorable charge dissociation, carrier transport and device performance. Here, the ortho‐, meta‐, and para‐isomers of phenylenediamine (PDA) are designed for 2D DJ tin halide perovskites. Theoretical simulation and experimental characterizations demonstrate that compared with p‐PDA and m‐PDA, o‐PDA shows larger dipole moment, which further reduces the exciton binding energy for the 2D perovskites. Besides, there is a strong hydrogen bond interaction between o‐PDA cation and inorganic octahedron, which not only improves the structural stability, but also induces larger aggregates in the precursor to form dense and uniform high‐quality films, and strengthens the antioxidant barrier. More interestingly, femtosecond transient absorption further proves that o‐PDA organic spacers can reduce unfavorable small n‐phases, resulting in sufficient and effective charge transfer between different n‐value. As a result, the 2D DJ (o‐PDA)FA3Sn4I13 solar cells achieve a record power conversion efficiency of 7.18%. The study furnishes an effective method to optimize the carrier transport and device performance by tailoring the chemical structure of organic spacers.
