Published: December 2022

AbstractNanofluids have been widely used as a class of promising working fluids with excellent heat transfer properties. However, the theoretical research on the thermal enhancement mechanism of nanofluids is still in the preliminary stage. Fractional constitutive models provide a new powerful tool to investigate the superior mechanical and thermal properties of nanofluids owing to their advantages in depicting the memory and genetic properties of the system. Fractional nanofluid models have become one of the hot research topics in recent years as better control of flow behavior and heat transfer can be achieved by considering fractional derivatives. The existing studies have indicated that the results obtained by the fractional-order nanofluid model are more consistent with the experimental results than traditional integer-order models. The purpose of this review is to identify the advantages and applications of fractional nanofluid models. First, various definitions of fractional derivatives and correlations of flux utilized in nanofluid modeling are presented. Then, the recent researches on nanofluids with fractional derivatives are sorted and analyzed. The impacts of fractional parameters on flow behaviors and heat transfer enhancement are also highlighted according to the Buongiorno model as well as the Tiwari and Das nanofluid model with fractional operators. Finally, applications of fractional nanofluids in many emerging fields such as solar energy, seawater desalination, cancer therapy, and microfluidic devices are addressed in detail.

Abstract

Purpose
This study examines the use of social media by individuals during protests in China (Hong Kong), Iraq, Iran, and Lebanon.

Method
Surveys in the four countries assess the relationship between people’s attitudes toward the protests and their selection bias on social media, manifested through selective sharing and selective avoidance.

Findings
Regardless of the different political and media systems in each country, social media usage was largely similar. Overall, our findings established that people’s attitude strength toward the protests was associated with their selective sharing behavior; those who scored high on supporting the protests were more likely than those who scored high on opposing the protests to share news that supports the protests, and vice versa. As for selective avoidance, social media protest news use emerged as the strongest predictor. The more individuals followed and shared protest news on social media, the more likely they were to engage in selective avoidance by hiding or deleting comments, unfriending or unfollowing people, and blocking or reporting people for posting comments with which they disagreed.

Implications
For selective sharing, our findings are consistent with extant research that found individuals with strong attitudes toward certain issues are more likely to express their opinions on social media. Also, for selective avoidance, our study supports the literature, which shows individuals practice selective avoidance to clean up their environment from attitude-inconsistent information, especially on social media, and exceedingly so during protests and crises.

Value
Selection bias places individuals into secluded groups and contributes to political divisions and polarization. Research has focused on online selective exposure and on offline selective avoidance, but online selective avoidance and sharing have rarely been studied. Our study contributes to emerging research on selective sharing and selective avoidance online during a period of polarization in multiple countries.
Pioneer Archaeologists and the Influence of Their Scientific Relationships on Mesolithic Studies in North Iberia

Published: December 2022

Abstract
Count Vega del Sella’s research marked the beginning of the long tradition of Mesolithic studies in Asturias (North Spain). Another pioneer, L. Sierra, explored a number of caves in Cantabria with Mesolithic shell-middens, but no specific research line was developed on this kind of deposit in the province. The early excavation at Santimamiñe Cave recorded the Basque Country’s first shell-midden, which was thought to belong to a different facies from the deposits in Asturias (Asturian shell-middens). Nevertheless, no line of research into the Mesolithic was developed in that area either. The first research on the Mesolithic in North Iberia did not take place in isolation from European Prehistoric studies at the time. In fact, the historiographical context was characterized by the existence of cordial relationships between the pioneers in this region and several foreign archaeologists. This feedback between Spanish and foreign archaeologists sometimes had a significant impact. In contrast, the relationships between Spanish authors were less intense. This situation and the recurring lack of information on the Mesolithic in Cantabria and the Basque Country did not encourage debate on the existence of different Mesolithic facies in northern Iberia. So for decades the Asturian and the eastern Mesolithic recorded in Cantabria and the Basque Country were regarded as independent objects of study. This indicates the relevance of the scientific relationships and other factors in the perception of the Mesolithic that took shape in the first decades of the twentieth century and which has been perpetuated until the present time.

Abstract
Objective: The current research investigates the surface texture and microstructural characterization of thin-walled Ti6Al4V along the build direction processed using laser powder bed fusion (LPBF) technology using an intra-comparison approach. Methodology: The two-dimensional and three-dimensional surface morphology and multi-scale surface roughness analysis of all Ti6Al4V samples were performed using an opto-digital microscope (with extended focus imaging coupled with high dynamic range imaging). Moreover, the scanning electron microscope, microhardness tester, and X-ray diffraction techniques were used to analyze the microstructural and microhardness values. Findings: (1) The lath thickness was relatively thicker in the LPBF-processed Ti6Al4V sample’s microstructure at central locations than in the top and bottom locations. (2) The areal surface roughness (Sa), Rk, and Sk values were relatively lower for the middle region than for the bottom and top regions of the thin-walled part, implying nonuniform surface topography along the build direction. (3) The middle region had a higher surface texture and texture amplitude symmetry periodicity than the top and bottom regions along the build direction. Value: Overall, the established methodology employed on the thin-walled Ti6Al4V part processed using LPBF technology enables the selection criteria of a suitable surface finishing process to achieve isotropic finish for practical industrial applications.

Purpose. To perform a critical analysis of approaches to determining the stress-strain state of the "horizontal working – layered massif" system. Obtain informed decisions for applying a specific approach to the case of a layered massif. To substantiate the metric of finite element models of the system "horizontal working – layered massif". Methodology. To achieve the purpose, the peculiarities of approaches to determining the stress-strain state of the system "horizontal working – rock massif" were analyzed. It has been proven that layering is the most important structural feature of the surrounding rock massif. A detailed analysis of mathematical methods for solving elastic-plastic problems for rock massifs was performed. Findings. During the analysis of solving the problem of determining the stress-strain state of the system "horizontal working – layered massif", two approaches were identified, each of which has its own set of methods. These approaches are analytical one and numerical, each of them has special features. It has been confirmed that recently the studies of the system "horizontal working - rock massif" are mostly based on the numerical approach, leaving only a small share of the total volume to the analytical one. It was determined that the introduction of numerical methods, in particular, the method of finite elements in specialized software complexes, allowed to change the concept of research in geomechanics and mechanics of underground structures, shifting the focus to mathematical and simulation modeling. Originality. Based on the results of the critical analysis of the approaches, the use of numerical analysis based on finite-element models is scientifically substantiated. It is this approach to determining the stress-strain state of the "horizontal working – layered massif" system that allows for layering to be taken into account without additional assumptions. Practical value. In the course of research, it has been proven that a spatial finite-element model from a flat prototype, but limited to a thickness of 0.1 or 1 m, is adequate for the given task, provided that plane deformation is considered.
Henri Michaux y el doble en su pintura
Authors: Biondi Valeria 
Published: December 2022

Este artículo intenta definir el doble en la pintura de Henri Michaux. El análisis considera dos características principales. La primera es la pre-identidad, o sea el valor originario que el autor pretende rescatar a partir de la identidad verdadera y vinculada a la construcción social. La segunda es la necesidad de investigar sobre lo inconsciente, para poder encontrar aquellas presencias que viven en nosotros y que podemos definir con el término “alteridad”. A partir de estos conceptos, se analiza la pintura de Michaux, destacando en esas cabezas desconocidas que, muchas veces, se manifiestan en la obra bajo la forma de una silenciosa muchedumbre.

Objective: This study aims to assess the knowledge, attitude, and practices regarding menstrual cups use and the factors associated with it among females of the reproductive age group in an urban setting of South Kerala.
Materials and methods: We conducted a cross-sectional study from December 2021 to January 2022 among females of the reproductive age group. Data was entered in MS Excel and was analyzed using Statistical Package for Social Sciences version 26.0. The significance of association was tested using the Chi-square test. Binary logistic regression was done to predict the factors associated with knowledge levels regarding menstrual cup.
Results: The mean age of study participants was 25.68(SD 6.64) years. Lack of knowledge (22.6%) and fear of insertion (56.2%) were the major reasons for not trying a menstrual cup. Out of the 350 study participants, 258(73.7%) had good knowledge scores and 92(26.3%) had poor knowledge scores. Discomfort and leakage were the most important problems reported by participants. A statistically significant association was found between younger age, educational status, socioeconomic, status, marital status of females in the reproductive age group, and knowledge about the menstrual cup.
Conclusion: Most of the participants (93.4%) were aware of menstrual cups. Even though two third of the participants had good knowledge regarding menstrual cups, only 15.1% have tried to use a menstrual cup. Fear of insertion was the most common concern for not trying a menstrual cup. Discomfort and leakage were the most important problems reported by participants. Younger age and higher educational qualifications were found to be independently associated with knowledge levels regarding menstrual cups.

Este artigo traz reflexões desenvolvidas a partir de pesquisa qualitativa de cunho documental sobre a Base Nacional Comum Curricular (BNCC) desde sua homologação aos desdobramentos para o processo de reelaboração dos Projetos Políticos Pedagógicos das instituições de educação. Foram analisados os documentos da BNCC e o “Guia para os gestores: orientações para formação continuada e revisão do Projeto Pedagógico à luz dos novos currículos”, documento produzido pelo “Movimento Pela Base”. A análise documental e os dados coletados na pesquisa revelam um elevado contexto de mudanças na área das políticas públicas brasileiras e mundiais. Em breve análise de discurso bakhtiniana observa-se o uso de enunciados dirigidos à responsabilização dos gestores sobre as garantias de uma educação de qualidade e a exclusão do termo: “político”, dos projetos pedagógicos a ser elaborados nas instituições de educação. Evidencia-se, portanto, a necessidade de participação da comunidade escolar nas decisões que orientem os rumos dados à educação, a fim de que haja uma quebra de paradigma, no sentido de viabilizar a efetiva gestão democrática na escola.

Background: Hospitalization has been a source of anxiety for young school-age patients. In addition to taking care of young patients’ physical problems, the primary caregivers will also encounter young patients’ emotional reactions. Understanding the anxiety status in young patients and primary caregivers to provide relevant measures is an important issue.Aim: To investigate the hospitalization anxiety levels in school-age children aged 6 to 12 years and primary caregivers, as well as their influencing factors.Subject and Methods: Cross-sectional research with a questionnaire survey was used as the methodology for the study. The enrollment period was between December 1, 2021, and August 31, 2022. For hospitalized young patients aged 6 to 12 years in the orthopedic ward of a medical center, after the consent was acquired at admission for 24 hours, the primary caregiver was assigned to complete the questionnaire.Result: The Post-Hospitalization Behavior Questionnaire (PHBQ) was used to investigate 39 young patients. The overall mean behavior scores was 51.5 ± 15.7 points, there were statistically significant differences for sex in general anxiety behavior scores, separation anxiety behavior scores, sleep anxiety behavior scores, apathy/withdrawal behavior scores, and total behavior scores, with higher post-hospitalization behavior scores in male young patients compared to that in females. In the Trait Anxiety Inventory for a family member, the mean score was 39 ± 12.6 points, with mild anxiety at 50%, moderate anxiety at 38.9%, and severe anxiety at 11.1%. Primary caregivers’ level of anxiety reached statistical significance in economic status, with an increased level of anxiety for those who were in lower economic positions (p=0.01).Conclusion: The PHBQ for young patients can be used as an assessment for their levels of anxiety, the levels of negative behaviors in boys are higher than that in girls. There were 50% of primary caregivers experienced moderate to severe anxiety, and the sources of anxiety were correlated with the economic status of the family.Recommendations:(1) Hospital anxiety in children is often overlooked and can be found by observing behavior. The PHBQ is an easy-to-use assessment tool and is recommended for routine use in hospitalized children to assess behavioral changes after pediatric surgery/hospitalization to help parents and medical staff evaluate children's anxiety.(2) Hospitals can construct amusement equipment, and toys or arrange game activities to reduce the anxiety of hospitalization of school-age children.
