Abstract
Ti-based electrode coated with MnOx catalytic layer has presented superior electrochemical activity for degradation of organic pollution in wastewater, however, the industrial application of Ti-based MnOx electrode is limited by the poor stability of the electrode. In this study, the novel Ti-based MnOx electrodes co-incorporated with rare earth (Ce) and conductive carbon black (C) were prepared by spraying-calcination method. The Ti/Ce:MnOx-C electrode, with uniform and integrated surface and enhanced Mn(IV) content by C and Ce co-incorporation, could completely remove ammonia nitrogen (NH4+-N) with N2 as the main product. The cell potential and energy consumption of Ti/Ce:MnOx-C electrode during the electrochemical process was significantly reduced compared with Ti/MnOx electrode, which mainly originated from the enhanced electrochemical activity and reduced charge transfer resistance by Ce and C co-incorporation. The accelerated lifetime tests in sulfuric acid showed that the actual service lifetime of Ti/Ce:MnOx-C was ca. 25 times that of Ti/MnOx, which demonstrated the significantly promoted stability of MnOx-based electrode by Ce and C co-incorporation.

Authors: Schulz dos Santos Paula , Cristina Barros da Silva Livia 
Published: September 2021

Dado o papel chave que a Embratur – Agência Brasileira de Promoção Internacional do Turismo tem no turismo nacional, sendo o órgão mais antigo do tipo em atividade, o presente trabalho propôs-se a estudar, de maneira qualitativa e exploratória, a construção de políticas públicas desde sua criação até os dias atuais, analisando as estratégias de promoção do Brasil no exterior. Para isso, realizou-se a análise documental da legislação, planos, programas e ações do órgão de 1966 a 2019. Os resultados foram analisados a partir das perspectivas de pesquisa avaliativa e análise de conteúdo, apontando para questões-chave a serem abordadas a partir de sua mudança de natureza jurídica ocorrida em 2020. As questões-chave são: a marca país; o regime de contratações; o acesso à recursos financeiros e tecnologias para melhor aproveitar os bens turísticos nacionais; a compreensão de sua própria história, a fim de evitar cometer novamente os erros do passado, como a não observação às tendências mundiais em promoção, utilização de linguagem de promoção com conotação sexual (desde as revistas dos anos 70 até o slogan “Brazil, visit and love us” e a falta de política norteadora clara para execução de suas ações.

A Casa da rua São Francisco: um caso folkcomunicacional do turismo de assombrações em Diamantina – MG
Authors: Nascimento Alan , Sousa de Oliveira Jéssica 
Published: September 2021

O Turismo de assombrações é um segmento do chamado turismo histórico-cultural. O processo de construção desse tipo de produto turístico suscita a questão de como é que os elementos próprios do mundo da tradição têm atraído as audiências modernas, turistas e viajantes. Na tentativa de oferecer uma resposta, este trabalho explora, conceitual e empiricamente, a turistificação de histórias de assombrações com base na noção de folkcomunicação. As técnicas de pesquisa adotadas pela investigação compreendem revisão bibliográfica e observação participante no city tour “Lendas do Tijuco”, realizado pela agência de turismo “Minhas Gerais”, na cidade de Diamantina-MG. Como resultado da investigação, sustenta-se que o turismo de assombrações se baseia num processo em que elementos da tradição local se mesclam com estéticas transnacionais, oriundas do cinema, da cultura pop do terror, das indústrias culturais, em geral, o que transforma almas penadas, a violência contra o escravo, a cultura funerária colonial, entre outras referências da morte de outrora, numa experiência turística, paradoxalmente, reconhecida e atual.

A Percepção da hospitalidade nas cidades do Porto, Portugal e Rio de Janeiro, Brasil
Authors: Valduga Manoela , Costa Carlos Manuel , Breda Zélia Maria 
Published: September 2021

O presente artigo tem como objetivo identificar e analisar a percepção da hospitalidade por parte de turistas internacionais nas cidades do Porto, em Portugal, e do Rio de Janeiro, no Brasil. O tema da hospitalidade é tratado teoricamente dentro de duas perspectivas distintas e até certo ponto antagônicas. De acordo com a corrente francesa de estudos, ela é considerada, resumidamente, como uma prática social, enquanto para a corrente anglo-saxônica ela assume valor comercial. Com o intuito de não influenciar os turistas entrevistados quanto às diferentes abordagens teóricas, optou-se pela metodologia de estudos denominada grounded theory, originalmente desenvolvida no campo da sociologia para áreas temáticas de pouca abordagem teórica, mas aqui adaptada para o oposto, que é quando um termo, de tão empregado, acaba por ter o seu significado distorcido. Os resultados, a partir da análise de conteúdo das entrevistas, identificaram oito categorias a posteriori de análise da hospitalidade, quais sejam: características da população, características dos empregados de bares, restaurantes, hotéis e similares, referência ao idioma/comunicação, características da cidade, infraestrutura turística, cuidado com o turista, sensação de exploração ao turista/turismo e mobilidade. Observou-se que as impressões pertinentes às pessoas, sejam residentes ou prestadores de serviço, foram categorias espontâneas com maior incidência, reforçando, em paralelo, a prevalência da chamada corrente de estudos francesa sobre a corrente de estudos anglo-saxônica, de viés comercial.

Recurrent Artery of Heubner Aneurysm Masquerading as Caudate Hemorrhage without Subarachnoid Hemorrhage in Moyamoya Disease: A Case Report and Literature Review
Authors: Li Youxiang , Fu Chao , Jiang Peng , Zhao Yang 
Published: September 2021

Background:
Clinically, the recurrent artery of the Heubner (RAH) aneurysm is extremely
rare, commonly presents with subarachnoid hemorrhage (SAH).

Case Report:
A 73-year-old man with a known moyamoya disease was presented as caudate hemorrhage
attributable to an incidental flow aneurysm distal on the right RAH, which was managed
conservatively after an unsuccessful endovascular attempt. Unfortunately, the patient died five
weeks after hospital discharge because of the re-rupture of the aneurysm. To the best of our knowledge,
the RAH aneurysm manifesting as caudate hemorrhage without SAH has not previously been
reported.

Conclusion:
This case highlights that the RAH aneurysm masquerading as caudate hemorrhage
without SAH is exceedingly rare but can be encountered, representing a diagnostic and therapeutic
challenge, and should be considered in the differential diagnosis. Moreover, early identifying and
then eliminating such vascular anomaly if possible is of importance to prevent fatal hemorrhage.
Computational Exploration of Functional Nanoscale Carbonaceous
Materials
Authors: Sereda Grigoriy , Uddin Md Tusar , Wente Jacob 
Published: September 2021

Background:
The unique ability of carbon to form a wide variety of allotropic modifications
has ushered in a new era in material science. Tuning the properties of these materials by functionalization
is a must-have tool for their design customized for a specific practical use. The exponentially
growing computational power available to researchers allows for the prediction and thorough
understanding of the underlying physicochemical processes responsible for the practical properties
of pristine and modified carbons using the methods of quantum chemistry.

Method:
This review focuses on the computational assessment of the influence of functionalization
on the properties of carbons and enabling desired practical properties of the new materials. The first
section of each part of this review focuses on graphene with nearly planar units built from sp2-
carbons. The second section discusses patterns of sp2-carbons rolled up into curved 3D structures in a
variety of ways (fullerenes). The overview of other types of carbonaceous materials, including those
with a high abundance of sp3-carbons, including nanodiamonds, can be found in the third section of
each manuscript’s part.

Conclusion:
The computational methods are especially critical for predicting electronic properties of
materials such as the bandgap, conductivity, optical and photoelectronic properties, solubility, adsorptivity,
the potential for catalysis, sensing, imaging, and biomedical applications. We expect that
introduction of defects to carbonaceous materials as a type of their functionalization will be a point
of growth in this area of computational research.
Endovascular Therapies for Type B Aortic Dissection
Authors: Makhija Rakhee R. , Mukherjee Debabrata 
Published: September 2021

:Aortic dissection is a life-threatening condition resulting from a tear in the intimal layer of the aorta, requiring emergent diagnosis and prompt multi-disciplinary management strategy for best patient outcomes. While type A dissection involving ascending aorta is best managed surgically due to high early mortality, Type B Aortic Dissection (TBAD) involving descending aorta generally has better outcomes with conservative management and medical therapy as a primary strategy is favored. However, there has been a recent paradigm shift in the management of TBAD due to late aneurysmal degeneration of TBAD, increasing morbidity and mortality in the long term. Late surgical intervention can be prevented by early endovascular intervention when combined with optimal medical therapy. In this narrative review, we explore available literature on different endovascular therapies for TBAD in different populations of patients.

Social Media Sharing of Articles About Measles in a European Context: Text Analysis Study
Authors: Wawrzuta Dominik , Jaworski Mariusz , Gotlib Joanna , Panczyk Mariusz 
Published: September 2021

Background
Despite the existence of an effective vaccine, measles still threatens the health and lives of many Europeans. Notably, during the COVID-19 pandemic, measles vaccine uptake declined; as a result, after the pandemic, European countries will have to increase vaccination rates to restore the extent of vaccination coverage among the population. Because information obtained from social media are one of the main causes of vaccine hesitancy, knowledge of the nature of information pertaining to measles that is shared on social media may help create educational campaigns.

Objective
In this study, we aim to define the characteristics of European news about measles shared on social media platforms (ie, Facebook, Twitter, and Pinterest) from 2017 to 2019.

Methods
We downloaded and translated (into English) 10,305 articles on measles published in European Union countries. Using latent Dirichlet allocation, we identified main topics and estimated the sentiments expressed in these articles. Furthermore, we used linear regression to determine factors related to the number of times a given article was shared on social media.

Results
We found that, in most European social media posts, measles is only discussed in the context of local European events. Articles containing educational information and describing world outbreaks appeared less frequently. The most common emotions identified from the study’s news data set were fear and trust. Yet, it was found that readers were more likely to share information on educational topics and the situation in Germany, Ukraine, Italy, and Samoa. A high amount of anger, joy, and sadness expressed within the text was also associated with a higher number of shares.

Conclusions
We identified which features of news articles were related to increased social media shares. We found that social media users prefer sharing educational news to sharing informational news. Appropriate emotional content can also increase the willingness of social media users to share an article. Effective media content that promotes measles vaccinations should contain educational or scientific information, as well as specific emotions (such as anger, joy, or sadness). Articles with this type of content may offer the best chance of disseminating vital messages to a broad social media audience.
Replicating Anatomical Teaching Specimens Using 3D Modeling Embedded Within a Multimodal e-Learning Course: Pre-Post Study Exploring the Impact on Medical Education During COVID-19
Authors: Stunden Chelsea , Zakani Sima , Martin Avery , Moodley Shreya , Jacob John 
Published: September 2021

Background
The COVID-19 pandemic has had significant effects on anatomy education. During the pandemic, students have had no access to cadavers, which has been the principal method of learning anatomy. We created and tested a customized congenital heart disease e-learning course for medical students that contained interactive 3D models of anonymized pediatric congenital heart defects.

Objective
The aim of this study is to assess whether a multimodal e-learning course contributed to learning outcomes in a cohort of first-year undergraduate medical students studying congenital heart diseases. The secondary aim is to assess student attitudes and experiences associated with multimodal e-learning.

Methods
The pre-post study design involved 290 first-year undergraduate medical students. Recruitment was conducted by course instructors. Data were collected before and after using the course. The primary outcome was knowledge acquisition (test scores). The secondary outcomes included attitudes and experiences, time to complete the modules, and browser metadata.

Results
A total of 141 students were included in the final analysis. Students’ knowledge significantly improved by an average of 44.6% (63/141) when using the course (SD 1.7%; Z=−10.287; P<.001). Most students (108/122, 88.3%) were highly motivated to learn with the course, and most (114/122, 93.5%) reported positive experiences with the course. There was a strong correlation between attitudes and experiences, which was statistically significant (rs=0.687; P<.001; n=122). No relationships were found between the change in test scores and attitudes (P=.70) or experiences (P=.47). Students most frequently completed the e-learning course with Chrome (109/141, 77.3%) and on Apple macOS (86/141, 61%) or Windows 10 (52/141, 36.9%). Most students (117/141, 83%) had devices with high-definition screens. Most students (83/141, 58.9%) completed the course in <3 hours.

Conclusions
Multimodal e-learning could be a viable solution in improving learning outcomes and experiences for undergraduate medical students who do not have access to cadavers. Future research should focus on validating long-term learning outcomes.

Published: September 2021

Background
Personal health records (PHRs) are eHealth tools designed to support patient engagement, patient empowerment, and patient- and person-centered care. Endorsement of a PHR by health care providers (HCPs) facilitates patient acceptance. As health care organizations in the Kingdom of Saudi Arabia begin to adopt PHRs, understanding the perspectives of HCPs is important because it can influence patient adoption. However, no studies evaluated HCPs’ acceptance of PHRs in the Kingdom of Saudi Arabia.

Objective
The aim of this study was to identify predictors of HCPs’ acceptance of PHRs using behavioral intention to recommend as a proxy for adoption.

Methods
This cross-sectional study was conducted among HCPs (physicians, pharmacists, nurses, technicians, others) utilizing a survey based on the Unified Theory of Acceptance and Use of Technology. The main theory constructs of performance expectancy, effort expectancy, social influence, facilitating conditions, and positive attitude were considered independent variables. Behavioral intention was the dependent variable. Age, years of experience, and professional role were tested as moderators between the main theory constructs and behavioral intention using partial least squares structural equation modeling.

Results
Of the 291 participants, 246 were included in the final analysis. Behavioral intention to support PHR use among patients was significantly influenced by performance expectancy (β=.17, P=.03) and attitude (β=.61, P<.01). No moderating effects were present.

Conclusions
This study identified performance expectancy and attitude as predictors of HCPs’ behavioral intention to recommend PHR to patients. To encourage HCPs to endorse PHRs, health care organizations should involve HCPs in the implementation and provide training on the features available as well as expected benefits. Future studies should be conducted in other contexts and include other potential predictors.

Authors: Rasool Aram Bakhtiar , Azar Bashar Hanna , Baram Aram 
Published: September 2021

Objectives: to find out the long-term results of tracheal reconstruction in terms of presentation, operation, complications, and outcomes of tracheal reconstruction.
Methods: In this case-series study, the patients who developed post-intubation tracheal stenosis following respiratory failure were followed up for two years for the possible complications. The patients were diagnosed by experienced pulmonologist in two surgical centers, Erbil and Sulaimaniya in Iraqi Kurdistan in 2017.
Results: The number of patients who were included in this study was 20; including males (n=13) and females (n=7) ranged between 18-58 years. The causes of the stenosis in patients were post-intubation (n=18) and post-tracheostomy for trauma (n=5). Most patients underwent extubation after 72 hours. The Myer-Cotton Grade of stenosis were grade 1 (n=1), grade 2 (n=13), and grade 3 (n=6). The major complications were dehiscence (n=3) and anastomotic edema (n=5). The minor complications were granulation (n=13) and mild anastomotic edema (n=1). One patient developed a surgical site infection and one patient developed a mild infection. The anastomotic fibrin deposition was developed in five patients. All patients had excellent satisfaction except for two patients (unsatisfactory). One of these patients died at month 1. The patients had normal medical conditions at different times of follow-ups.
Conclusions: This study showed that the results of the patients with post-traumatic tracheal stenosis were acceptable at different times for most of them.
