Isotopic responses of magnesium to two types of dissolution-reprecipitation processes for the growth of the double-carbonate mineral norsethite
Authors: Liu Chuan , Wang Kai , Li Weiqiang 
Published: February 2022

Abstract
An important mechanism of carbonate mineral growth is dissolution-reprecipitation, including the transformation of amorphous precursor to crystalline carbonates, and coarsening (ripening) of fine carbonate crystals. However, the mechanistic details of cation exchange associated with carbonate mineral growth via a dissolution-reprecipitation process are still not well understood. In this study, we used Mg isotopes to probe the exchange of Mg between aqueous solutions and norsethite [BaMg(CO3)2] by systematic synthesis experiments. Norsethite is a model double carbonate, with a general formula of AB(CO3)2, where A and B stand for two different divalent ions. Formation of norsethite is comprised of three stages, including: (1) precipitation of barium-magnesium (Ba-Mg) amorphous carbonate; (2) transformation of Ba-Mg amorphous carbonate to nano-crystalline norsethite by fast dissolution-reprecipitation; and (3) coarsening (ripening) of nano-norsethite by slow dissolution-reprecipitation. Magnesium isotopes displayed distinct fractionation behaviors in each of the three stages. The Mg isotope fractionation factors (∆26Mgsolid-aq) associated with precipitation of Ba-Mg amorphous carbonate were slightly negative and temperature-dependent, from –0.83‰ at 30 °C to –0.53‰ at 70 °C. During the transformation of Ba-Mg amorphous carbonate to nano-crystalline norsethite, isotopically light Mg isotopes were further enriched in the solid phase, with apparent ∆26Mgsolid-aq decreasing to –2.12‰ at 30 °C and –1.56‰ at 70 °C. In the ripening stage, norsethite became isotopically heavier, with ∆26Mgsolid-aq increasing up to –1.95‰ at 30 °C and –1.17‰ at 70 °C. The experimental results show that non-equilibrium isotope fractionation occurred during the transformation of amorphous carbonate to nano-crystalline norsethite (i.e., fast dissolution-reprecipitation). By contrast, the subsequent ripening of the norsethite led to the evolution toward isotopic equilibrium of the system by slower exchange with a longer reaction time (i.e., slow dissolution-reprecipitation). Moreover, our first-principles calculation results indicate that the equilibrium isotope fractionation was approached, but not attained, even after 276 days of recrystallization at temperatures below 70 °C. In short, this study has identified two different types of dissolution-reprecipitation process during the carbonate mineral growth and highlights the importance of understanding formation mechanism and post-depositional history of carbonate in interpreting the isotopic data of carbonate minerals.

Multi-objective Rao algorithm in resilience-based optimal design of water distribution networks
Authors: Jain Priyanshu , Khare Ruchi 
Published: February 2022

Abstract
Multi-objective meta-heuristics are used to optimize water distribution networks (WDNs) as they can achieve a near-optimal balance between cost and resilience in a unified platform. Most of these algorithms include tuning of algorithm-specific control parameters for higher optimization efficiency, leading to an increased computational effort. The current study is inspired by the desire to address the above problem. The goal is to formulate a multi-objective Rao algorithm (MORao) considering an existing modified resilience index (MRI) in the optimal design of WDNs. The model is demonstrated to attain Pareto-optimal solutions to complex WDN problems without exclusive parameter tuning. The algorithm is written in Python and is linked to a hydraulic model of a WDN implemented in EPANET 2.2 using pressure-driven demand (PDD) analysis. The method is demonstrated on three widely used networks: Two-loop, Goyang, and Fossolo. The Pareto-optimal solutions examine a tradeoff between two objectives to recognize competitive solutions. The network's resilience is increased 2.5 times by only 0.8 times increase in least-cost of Two-loop network. This research indicates that this method can achieve a satisfactory level of performance with a limited number of function evaluations.
Numerical investigation of the flow-field characteristics around the suspended pipeline under oblique flows
Authors: Yang Qinghua , Yang Qian , Zhang Yuqian 
Published: February 2022

Abstract
The flow field distribution around the suspended pipeline is closely related to the mechanical characteristics and local scour characteristics of the underwater crossing pipelines. To fully investigate the velocity distribution and wake structure characteristics around the suspended pipeline under oblique flows, a flume model test and a numerical simulation based on the LES (Large Eddy Simulation) method were performed. The results showed that the velocity distribution near the suspended pipeline under oblique flows had obvious three-dimensional characteristics. The influence range of pipeline on velocity is 1 d before to 6 d behind the pipeline (d is pipeline diameter). The smaller the flow angle, the more disordered the velocity distribution is. The larger the flow angle, the greater the variation degree of the velocity at each section at the same section is, as well as the higher the velocity deficit value is. In addition, the larger the angle of pipe flow, the more violent the wake structure changes with the flow velocity, and the stronger the regularity of vortex street shedding. This research provides a theoretical reference for the scour prevention design and safe operation of crossing pipelines.
Weight Loss Trajectories and Related Factors in a 16-Week Mobile Obesity Intervention Program: Retrospective Observational Study
Authors: Kim Ho Heon , Kim Youngin , Michaelides Andreas , Park Yu Rang 
Published: February 2022

Background
In obesity management, whether patients lose ≥5% of their initial weight is a critical factor in clinical outcomes. However, evaluations that take only this approach are unable to identify and distinguish between individuals whose weight changes vary and those who steadily lose weight. Evaluation of weight loss considering the volatility of weight changes through a mobile-based intervention for obesity can facilitate understanding of an individual’s behavior and weight changes from a longitudinal perspective.

Objective
The aim of this study is to use a machine learning approach to examine weight loss trajectories and explore factors related to behavioral and app use characteristics that induce weight loss.

Methods
We used the lifelog data of 13,140 individuals enrolled in a 16-week obesity management program on the health care app Noom in the United States from August 8, 2013, to August 8, 2019. We performed k-means clustering with dynamic time warping to cluster the weight loss time series and inspected the quality of clusters with the total sum of distance within the clusters. To identify use factors determining clustering assignment, we longitudinally compared weekly use statistics with effect size on a weekly basis.

Results
The initial average BMI value for the participants was 33.6 (SD 5.9) kg/m2, and it ultimately reached 31.6 (SD 5.7) kg/m2. Using the weight log data, we identified five clusters: cluster 1 (sharp decrease) showed the highest proportion of participants who reduced their weight by >5% (7296/11,295, 64.59%), followed by cluster 2 (moderate decrease). In each comparison between clusters 1 and 3 (yo-yo) and clusters 2 and 3, although the effect size of the difference in average meal record adherence and average weight record adherence was not significant in the first week, it peaked within the initial 8 weeks (Cohen d>0.35) and decreased after that.

Conclusions
Using a machine learning approach and clustering shape-based time series similarities, we identified 5 weight loss trajectories in a mobile weight management app. Overall adherence and early adherence related to self-monitoring emerged as potential predictors of these trajectories.
A Web-Based Escape Room to Raise Awareness About Severe Mental Illness Among University Students: Randomized Controlled Trial
Authors: Rodriguez-Ferrer Jose M , Manzano-León Ana , Cangas Adolfo J , Aguilar-Parra Jose M 
Published: February 2022

Background
People with severe mental illness (SMI) face discriminatory situations because of prejudice toward them, even among health care personnel. Escape rooms can be a novel educational strategy for learning about and empathizing with SMI, thus reducing stigma among health care students.

Objective
This study aimed to examine the effect of the Without Memories escape room on nursing students’ stigma against SMI.

Methods
A pre- and postintervention study was conducted with a control group and an experimental group. A total of 306 students from 2 Andalusian universities participated in the study. Data were collected through a pre-post study questionnaire, consisting of an adapted version of the Attributional Style Questionnaire and a questionnaire on motivation for cooperative playful learning strategies. The control group carried out an escape room scenario without sensitizing content, whereas the experimental group carried out an escape room scenario on SMI, with both escape rooms being carried out in a 1-hour session of subjects related to mental health. To answer the research questions, a 2-way analysis of variance with repeated measures, a linear regression, and a 2-way analysis of variance were performed.

Results
After the intervention, a significant reduction (P<.001) was observed in the experimental group in stigmatizing attitudes compared with the control group, in which no statistically significant changes (P>.05) were observed. In contrast, the linear regression (t195=−22.15; P<.001) showed that there was an inverse relationship between flow and the level of reduced stigma. When controlling for having or not having a close relative, the intervention was also shown to be effective (P<.001) in reducing the stigma displayed, both for people with affected and unaffected relatives.

Conclusions
Our findings suggest that the Without Memories escape room can be used as an effective tool to educate and raise awareness about stigmatizing attitudes toward SMI in university students studying health care. Future testing of the effectiveness of educational escape rooms should be designed with new programs through playful strategies of longer duration to evaluate whether they can achieve a greater impact on motivation, acquisition of knowledge, and awareness. In addition, the feasibility of implementing the Without Memories escape room in other careers related to health and community should be investigated.

Authors: Jaeger Bruna Coelho , Bastos Izabela Mota 
Published: February 2022

Essa pesquisa tem como objetivo analisar como a Nigéria tem utilizado o Nation Branding na reconstrução da sua imagem e na reorientação da sua política, sobretudo no contexto pós-crise de 2008 e na sua inserção no comércio internacional. Dessa forma, a análise será feita de forma explicativa e através de uma crítica histórica, a partir do construtivismo de Wendt e a teoria sobre construção de ideias e poder. De modo complementar, propõe-se um diálogo entre o construtivismo e a teoria decolonial, pois as normas e ideias construídas pelas grandes potências perpetuam uma estrutura de poder colonial. Isto posto, a pergunta que guia o artigo é: de que forma a construção do Nation Branding na Nigéria, no período de 2009 a 2019, tem impactado na inserção internacional do país? A hipótese apresentada é que, ao implementar o Nation Branding, com políticas além de turismo, ocorreu consequentemente o fomento do capital humano e da independência econômica do país, bem como uma revolução digital através das startups nigerianas. Por fim, realiza-se pesquisas quantitativas e qualitativas, através de autores nigerianos, a fim de evidenciar a versão africana da história, bem como contribuir para a superação de estereótipos enraizados em nossa sociedade.
Aksjonslæring som grunnlag for utvikling av lærerstudenters U-kompetanse i FoU-oppgaven
Authors: Antonsen Yngve , Thunberg Odd Arne , Andreassen Svein-Erik 
Published: February 2022

Den nye norske femårige grunnskolelærerutdanningen har som mål at studentene skal utvikle sin FoU- ompetanse. I artikkelen undersøker vi hvordan aksjonslæring i FoU-oppgaven kan bidra til lærerstudenters kompetanse i utviklingsarbeid. Vi har induktivt og deretter deduktivt analysert 51 kvalitative semistrukturerte intervjuer med lærerstudenter som har gjennomført aksjonslæring som en del av FoU-oppgaven på det tredje året av en femårig integrert masterutdanning. Vi har komplementert datamaterialet ved å analysere fire av studentenes FoU-oppgaver. Det teoretiske begrepsapparatet for den deduktive analysen er Dales (1989) kompetanseområde K3, som dreier seg om læreres kompetanse i utviklingsarbeid. Til K3 knytter Dale tre kjennetegn: konstruksjon av hverdagsteori, forskningsavstand til egen praksis og kritisk drøfting i førsteperson. Studien viser at aksjonslæring i FoU-oppgaven bidro til å gi lærerstudentene kompetanse, som de anvendte til å reflektere over og forbedre sin egen praksis, i tråd med Dales tre kjennetegn på K3-området. Studien viser imidlertid også at utdanningsinstitusjonen sendte studenter ut i praksis uten å ha forberedt praksislærerne på aksjonslæring og etablering av et lærende partnerskap.
English abstract
English title: Action learning as a basis for the development of teacher students’ D competence in the R&D thesis
The new Norwegian five-year teacher education for primary and lower secondary school aims for developing students’ R&D competence. We examine how action learning in the R&D thesis can contribute to teacher students’ competence in development work. This is done by inductive and then deductive analysis of 51 qualitative semi-structured interviews with teacher students who have completed action learning as part of the R&D thesis in the third year of their five-year integrated master’s education. In addition, we examined four of the students’ R&D thesis. The theoretical framework for the deductive analysis is Dale’s (1989) third area of competence, K3, which is about teachers’ competence in development work. Dale attaches three characteristics to K3: construction of everyday theory, research distance to own practice and critical discussion in the first person. The study shows that action learning in the R&D thesis contributed to giving the teacher students competence, that they used to reflect on and improve their own practice; this is in line with Dale’s three characteristics in the K3 area. However, the study also shows that the educational institution sent students out for internships without having prepared the internship teachers for action learning and the establishment of a learning partnership.
Composite mechanical performance of prefabricated concrete based on hysteresis curve equation
Authors: Fu Yanan 
Published: February 2022

Abstract
The angle steel-concrete column used in the new frame structure means that the rigid angle steel is placed in the column instead of the longitudinal reinforcement. The steel plate hoop welded to the longitudinal angle steel is used instead of the stirrup to form a spatial steel frame and concrete component. To ensure the normal use of existing houses in the building and adding floors, avoid transferring the load during the construction phase to the roof of the original house. The corresponding skeleton curve is extracted from the hysteresis curve of the specimen. Based on experimental research, the force performance of the normal section of the angle steel-concrete column was discussed, and the calculation formula of the normal section bearing capacity of the angle steel-concrete column was discussed.
