Autism spectrum disorder (ASD) is a developmental disability caused by differences in the brain. People with ASD often have challenges with socializing interacting with people around them, their behaviors and interests are restricted and repetitive. Children with ASD might face some difficulties in the way they learn or interact, which might interfere with their general health and especially their oral health, since they might need the dexterity and will of obtaining a good oral health. We’ve conducted a study on some of the children with ASD in Saudi Arabia to screen their general oral health using the dmft system by the WHO. The aim of this study is to analyze the oral health status of the ASD children in Saudi Arabia and to sense whether we need a room for improvement in their oral health awareness and knowledge.

Authors: Moussa Doumbia  , Daouda Sevede  , Viviane Kouakou  , Pascal Pineau  , Mireille Dosso
Published: August 2023

Background: In Ivory Coast, as in the rest of sub Saharan Africa, despite the introduction of anti-hepatitis B vaccine, toddlers and children remain a segment of the population frequently infected with Hepatitis B Virus (HBV). The conditions of early HBV transmission, and notably the materno-fetal route remain summarily documented in sub Saharan Africa. Methods: From June to November 2018, we analyzed the socio-demographical, serological, and viral features related to HBV transmission in expectant mothers and their newborns who came for delivery at the CHU Cocody Abidjan. Results: Out of 1628 contacted expectant mothers, a subset of 508 accepted to participate to the study, including 163 who were positive for HBsAg. All 56 mothers who transmitted either HBsAg or HBV DNA to their babies were presenting HBV DNA loads >5.0 log10 IU/mL Remarkably, fates of newborns either positive for HBsAg or HBV DNA who completed immune-prophylaxis were drastically different at 9-12 months. While a majority (90%) of HBsAg (+)-only babies became anti-HBs (+), 62.5% DNA-positive newborns failed to mount a proper anti-HBs response. Overall, 10.7% of newborns with at least one positive HBV marker at birth develop a bona fide chronic infection at 9 months. Conclusions: In Ivory Coast, pregnant women presenting HBV DNA loads above 5.0Log10 IU/mL are at risk of maternofetal transmission. Presence of HBV DNA in the blood of newborns represents a better predictor of anti-HBV immunization failure than HBsAg presence. An adaptation of immunization procedures with a passive immune prophylaxis targeting specifically newborns at risk should be urgently considered.

Authors: Янь Гуанхуа , Ян Сюйдун , Гу Цзяньфэн , Чуаньвэй Чуаньвэй
Published: July 2023

Исследовано влияние лазерного упрочнения и газового азотирования на микроструктуру и износостойкость стали Р20 (российский аналог 38ХНМ). Определен фазовый состав и микротвердость упрочненного поверхностного слоя, исследована его микроструктура. Проведены испытания на изнашивание. Установлено, что оба способа обработки повышают твердость стали. Однако при одинаковой твердости поверхности азотированный слой обладает более высоким сопротивлением пластической деформации и модулем вдавливания, а также значительно более высокой износостойкостью, чем слой, упрочненный лазерной закалкой. Показано, что лазерное упрочнение поверхности обеспечивает получение более глубокого упрочненного слоя, а газовое азотирование — более высокую износостойкость стали Р20.

Published: July 2023

Разработана модель размещения атомов примеси внедрения в аустените железа, в соответствии с которой при введении атома примеси внедрения происходит превращение регулярной плотной упаковки (ГП или ГЦК) из октаэдров и тетраэдров в локальную призматическую упаковку типа цементитной путем переброски диагоналей (diagonal flipping). Углерод растворяется в кристаллической структуре аустенита железа как центрированный пятиатомный тетраэдрический кластер, который является фрагментом упаковки углерода в кристаллической структуре алмаза. Тогда при диффузии атома примеси в соседнем периоде решетки происходит преобразование в призму, а призматическая упаковка в исходном месте нахождения примесного атома обратно реконструируется в обычную междоузельную пустоту. В целях проверки адекватности предложенной модели выполнены теоретические расчеты энтальпии активации диффузии углерода и азота в аустените, согласно которым энтальпия активации соответственно равна: 149 ± 20 и 155 ± 20 кДж/моль, что удовлетворительно соотносится с экспериментальными данными, приведенными в литературе: 153 и 169 кДж/моль.

Unraveling Depression: How Modern Pressures Shape Our Minds and Choices
Authors: Jin Ruining
Published: July 2023

In contemporary society, escalating societal pressures have precipitated a rise in the number of individuals suffering from depression. Far from being a mere individual concern, depression has emerged as a significant societal challenge. Central to the experience of depression is the diminishing positive effect, causing a decline in interest and motivation toward life. As a result, societal positives, such as professional accomplishments, familial bonds, and social interactions, become markedly less attractive. Studies have shown that individuals with depression often struggle with emotion regulation when faced with positive situations, tending towards negative interpretations of events. These cognitive distortions substantially impact their daily functioning and interpersonal relations [1].
Analyzing the Impact of the Covid-19 Pandemic on Stock Market Investments
Authors: S Ramya
Published: August 2023

The Covid-19 pandemic has had a notable impact on financial markets, prompting individuals to reevaluate their risk and return objectives and modify their investment portfolios. This study aims to examine the pandemic's influence on the portfolio allocation decisions of individual investors. It investigates investors' perceptions and preferences concerning different investment strategies both before and during the period of heightened anxiety caused by the Covid-19 pandemic. The data for the study was collected from individual investors residing in Delhi and Mumbai. The Analytical Hierarchy Process (AHP) was utilized to rank the investment choices of the participants. The findings indicate that, owing to the current economic uncertainty associated with the pandemic, investors have started realigning their portfolios. As the predictability of returns on risky assets has decreased, investors are shifting towards more conservative portfolios. Nevertheless, the extent of the transition from high-risk to low-risk assets varies among individual investors.

Published: August 2023

This study presents the ostracod clumped-isotope (∆47) thermometer, a new tool that provides quantitative temperature and hydrological reconstruction from lacustrine systems, which are among the best archives to reconstruct continental paleotemperature variations. The relationship between ∆47 and the temperature at which ostracod shell crystallized, is determined by measuring ∆47 on different species grown under controlled temperatures in both natural environments (4 ± 2°C; 12 ± 1°C) and lab cultures (23 ± 0.5°C). No consistent offset between the two species originating from the same environment and precipitated at the same temperature is reported, suggesting the absence of a vital effect in ostracod ∆47. In addition, the excellent agreement between the presented ostracod data and the carbonate clumped-isotope unified calibration (Anderson et al., 2021) suggests that the use of the latter can be extent to continental biogenic carbonates that do not present a kinetic effect. The ostracod-∆47 thermometer constitutes a reliable tool for continental palaeoclimate reconstructions that can be widely used in freshwater systems in all climatic belts.
Positive—More Than Unbiased—Self-Perceptions Increase Subjective Authenticity
Authors: Bailey Erica R. , Iyengar Sheena
Published: August 2023

Authenticity is often described using terms like “real”, “genuine”, and “true” suggesting that unbiased and objective self-perception is a core component of the construct. However, people tend to view themselves in an overly positive way. Therefore, we propose that experiencing a positive self—vs. an unbiased self—will increase authenticity. We find support for this in seven studies (Ntotal=1,795) with two operationalizations of self-rated authenticity: attributed and state authenticity. We find that authenticity emerges from positive self-beliefs (Study 1), positive personality assessments (Study 2), and positive self-expressions (Study 3a-3b). Further, we find that these effects are not driven only by positivity, but positive selves (Study 4), and mediated by the identity centrality (Study 5). Finally, Study 6 finds that this positivity bias does not extend to other-rated authenticity: people who present an overly positive self seem less authentic to others relative to a mixed or negative self-presentation. Taken together, these findings suggest that being “unreal” through positive self-illusions can, paradoxically, make one feel more real.
Different Roles of Teachers in the ELT Classroom
Authors: Poudel Nab Raj
Published: August 2023

This article explores the expected roles of language teachers in an ever-shifting English language teaching scenario. It introduces the traditional roles of language teachers and goes on to discover new roles evolved because of the new theories and innovations in this field. While analysing and interpreting, I reviewed the related literature on the concerned topic to review the roles of English language teachers in the language classroom. After the systematic thematic review of the literature, I, as part of the findings, concluded that the language teachers’ roles are always evolving and bend towards consenting autonomy to the learners for providing them more control over their own learning. The roles assumed by the teachers are that of a facilitator, an assessor, a manager, a guide, a resource provider, a digital enthusiast, a cultural diplomat, and many others. A language teacher should be smart and flexible enough to morph into various roles as per the context and needs of the teaching-learning situation in the classroom. There is a continual need of exploring more plausible roles which can expedite language learning in more systematic and organized yet effective ways.
CLT and Task-Based Instruction for Effective Learning
Authors: Shahi Nem Bahadur
Published: August 2023

The goal of Communicative Language Teaching is to develop fluency in language use. It emerged for better interaction like native speakers. Significantly, using the CLT approach increases communicative competence which is more reliable in language teaching. CLT is a broad approach to teaching that resulted from a focus on communication as the organizing principle for teaching. It helps language teachers achieve maximum learning among the learners rather than focus on mastery of the grammatical system of the languages. Task Based Instruction focuses on classroom activities involving two or more learners using communication strategies and interactional skills.
Exploring Feminism on Ghãtu Cultural Site
Authors: Gurung Rajan Kumar
Published: August 2023

This paper analyzes Ghãtu cultural site from a feminist approach. Ghãtu cultural site has been studied mostly from the anthropological point of view but it has not been studied from this approach. The study explores feminism on this site to make the readers aware of female identity and gender equality by teaching feminism in EFL classes because society is not free from the grip of male domination. The pedagogical implications are to make the students or the new generation aware of gender discrimination. Most females think that their misfortune victimizes them but this paper attempts to prove that it is not. This paper suggests that misfortune should be changed into good fortune. According to the theory of feminism, the female voice should be addressed. Ghãtu cite is a burning example of extreme male domination. The sati system, immolation, compels queen Yemphawati, to jump into the burning pyre of her husband. The findings of the study show that society has been knowingly or unknowingly dominating and using females yet. This essay protests the conservative thought of a patriarchal society. Still, some males are guided by such a poor mentality and they want to dominate females. The study is about maintaining the balance between male-female so that a win-win game will be there. The trend of othering never results positively. And this paper forwards these questions. Why do males treat females as commodities in Ghãtu? What are the main reasons of the over-domination of females? Are females weaker than males?
