Authors: Moura Isabelle Garcia , Rufino Emanuel Bezerra , Silva Jardel dos Santos , Oliveira Lara Pepita de Souza 
Published: December 2024

Introdução: A Odontologia Biomimética utiliza protocolos para maximizar a adesão, preservar a vitalidade pulpar, minimizar tensões de polimerização, entre outros. Sendo assim, a técnica semidireta com esses princípios aumenta a durabilidade de restaurações em dentes extensamente destruídos. Este trabalho objetiva apresentar um caso clínico de um dente vital em cavidade profunda seguindo protocolos biomiméticos. Metodologia: Paciente de 28 anos compareceu à Faculdade IAES queixando-se de uma restauração insatisfatória no dente 46. Radiograficamente, observou-se proximidade pulpar, mas, ao teste de vitalidade, o dente estava vital. Clinicamente, a restauração mostrava-se insatisfatória, com todas as cúspides fragilizadas, portanto, seguindo protocolos para prevenção de fratura do remanescente, foi realizado o rebaixamento de cúspides menores que 2mm, além de remoção seletiva do tecido cariado, preservando a dentina afetada na região mais próxima da polpa. Seguindo o princípio de “zona de selado periférico”, foi mantida uma zona de esmalte e dentina sadios em todo o entorno do preparo, seguido da profilaxia. Após isso, procedeu-se com os passos adesivos: adesivo universal, camada de 1mm de resina flow e blindagem do preparo com resina composta (biobase). Esse preparo foi moldado com alginato e gesso pedra e a peça confeccionada para cimentação na consulta seguinte. Os passos respectivos no dia da cimentação consistiram em: avaliação da adaptação interna da peça, profilaxia (peça e preparo), asperização interna com pontas FF (peça e preparo), limpeza com ácido fosfórico 37% (peça e preparo), silano por 1 minuto (peça), sistema adesivo (peça e preparo) e cimentação com resina flow. Resultados e Discussão: Revisões sistemáticas apontam que o emprego de materiais de proteção pulpar indireta não é mais necessário para preservação da vitalidade e prevenção de exposições pulpares, uma vez que seja realizada a avaliação prévia da vitalidade, remoção de todo o tecido contaminado nas margens do preparo, manutenção de uma margem segura de dentina afetada na parede pulpar e não utilização de ácido fosfórico em dentina (adesivos universais ou autocondicionantes). Conclusão: A aplicação dos protocolos biomiméticos na técnica semidireta demonstra eficácia na preservação da vitalidade pulpar sem necessidade de materiais de proteção pulpar tradicionais, favorecendo a abordagem restauradora de dentes extensamente comprometidos.

Published: December 2024

Aim of the Study: The current study examined the association of gender role attitudes and emotional intelligence of married individuals. The second objective of this study was to assess the role of work status and gender as moderators for predicting the relationship of gender role attitudes with emotional intelligence of married individuals.
Methodology: A sample of married working men and women (N = 500), both working, and housewives was selected. Purposive and convenient sampling technique was used for data collection. Indigenous versions of perceived emotional intelligence and gender role attitudes measures were used to collect the data. The results of alpha coefficients for the scales and its subscales indicated satisfactory reliability levels as evidence for the stability of scores. Assessment of correlation coefficients exhibited significant positive relationship of emotional intelligence with gender role attitudes, which projected that higher self-perceived emotional intelligence resulted higher egalitarian gender role attitudes.
Findings: Correlation analysis suggested that emotional self-regulation, emotional self-awareness, and interpersonal skills as sub facets of emotional intelligence were found positively correlated with gender role attitudes. Independent moderation models were tested to explore the effect of gender and work status as moderator. These results indicated that moderation effect was significant for women than men, while across work status, it was found that moderation effect was significant for housewives and married working women than married working men into the positive direction.
Conclusion: To conclude this empirical evidence are vital contributions drawn from the collectivistic and traditional socio-cultural context of Pakistan.

COVID-19 have an unusual breakout around the end of 2019. Due to lock down situations the online education has become the popular alternative to conventional face to face teaching, yet it comes with some issues and challenges faced by online teachers. The purpose of this study is to investigate the challenges faced by the male and female conventional teachers shifted to online teaching due to this Pandemic. This paper focused on challenges such as pedagogical, technological, time management, online group assessments and lack of interaction. The study conducted using questionnaire survey. A sample of 70 teachers from different university of Lahore, Pakistan was selected. A five point scale questionnaire was developed to collect the data. Frequencies and percentage were used to analyze the overall perception of online teachers about the issues they faced. Independent samples t-test was applied to assess the difference in the perception and experiences of male and female teachers while teaching in an online setting. The correlation analysis was also applied to assess the association among the above-mentioned factors. It was observed that the teachers are mostly facing the pedagogical issues including unfamiliar courses, less visible connection with the students, multitasking and improvements in course contents, time management due to heavy workloads. Only a few teachers are facing technological issues. Most of the teachers found satisfied with the process of assessing the students in online learning. No gender differences were found regarding the issues except that female instructors face more technology-related issues than male. This research provide a baseline to investigate challenges faced by teachers in online space. To address the challenges like Pedagogical, technological, time management, online group assessments and lack of interaction, higher education institutions need to provide training, support and opportunities for the continuous professional development of teachers.

Authors: Yousaf Hazrat , Khan Gulawar , Khan Adnan 
Published: December 2024

Aim of the Study: The main aim of this research paper is to analyze the behavior of households' budget expenditures on education and health in the province of Balochistan. There are several reasons for our study to select Balochistan, but the most important reason is that Balochistan is the largest province of Pakistan.
Methodology: For this quantitative research, the descriptive statistic, Pearson correlation and Working-Leser model.
Findings: Amongst health categories, households spend lion share of their budget on medicine and education categories, they spend more on school/ college/ university fees. The Pearson correlation result suggests that budget allocation to health is strongly negatively correlated with logarithm income while obtaining a positive correlation between budget allocation to education and logarithm income. Correlations between household size and budget allocation to health and education were negative while a positive correlation between budget allocation to health and employee, and between budget allocation to education and employee. The econometric result suggests that income, household size and employment status are the key drivers for determining household budget allocation to education and health.
Conclusion: The rise in employment and controlling policy of household size could be a valid policy options while the income elasticity is suggesting that rise in income could also be a valid policy option in case of Balochistan for rising budget allocation to health and education.
De l’exaltation : une lecture écoféministe de deux romans d’Anaïs Barbeau-Lavalette1
Authors: Lepage Élise 
Published: December 2024

Dans Femme forêt (2021) et Femme fleuve (2022) d’Anaïs Barbeau-Lavalette, une narratrice s’immerge dans un milieu naturel où elle vit des expériences de profonde exaltation. Cet article propose une lecture écoféministe de ces deux romans en faisant ressortir comment l’écriture de Barbeau-Lavalette « recycle », pour les resémantiser, des métaphores usuelles et les intègre dans une rhétorique de la porosité entre le sujet et son environnement. Elle développe par ailleurs des images de métamorphoses montrant des formes de vie qui se transforment au sein de leurs milieux naturels. En valorisant la cyclicité et la porosité des êtres, ces romans remettent en question les hiérarchisations biologiques et appellent de nouvelles approches épistémologiques.
Vers un devenir-proie ? Chasse et oppression dans Le Lièvre d’Amérique (2020) de Mireille Gagné1
Authors: Defraeye Julien 
Published: December 2024

Dans Le Lièvre d’Amérique (2020), dont le titre pointe vers le récit de chasse mythique L’Élan d’Amérique (1972) d’André Langevin, Mireille Gagné narre la métamorphose quelque peu kafkaïenne de sa protagoniste : celle-ci ne se change non pas en « monstrueux insecte », à l’instar de Gregor Samsa, mais en lièvre – ou en hase, la femelle du lièvre –, à la suite d’une procédure d’altération de son génome, dans un futur transhumaniste que l’on nous présente comme prochainement envisageable. Dans ce roman / journal, la plupart des entrées sont datées par rapport au jour J de l’intervention, balise temporelle qui marque l’enclenchement du processus de mutation. Diane, dont le prénom renvoie à la déesse de la chasse dans la mythologie romaine, note les transformations physiques liées à l’opération, mais témoigne surtout d’un rapport changeant à son environnement, professionnel notamment, ainsi que dans sa relation à l’altérité masculine.

Published: October 2019

Over the last few decades, the number of cases of non‐melanoma skin cancer (NMSC) has risen to over 3 million cases every year worldwide. Members of the ERBB receptor family are important regulators of skin development and homeostasis and, when dysregulated, contribute to skin pathogenesis. In this study, we investigated leucine‐rich repeats and immunoglobulin‐like domains 2 (LRIG2), a transmembrane protein involved in feedback loop regulation of the ERBB receptor family during NMSC. LRIG2 was identified to be up‐regulated in various types of squamous cell carcinoma (SCC), but little is known about LRIG2 in cutaneous SCC (cSCC). To investigate the function of LRIG2 in cSCC in vivo, we generated a skin‐specific LRIG2 overexpressing transgenic mouse line (LRIG2‐TG) using the Tet‐Off system. We employed the 7,12‐dimethylbenz(a)anthracene/12‐O‐tetra‐decanoylphorbol‐13‐acetate (DMBA/TPA) two‐stage chemical carcinogenesis model and analyzed the skin during homeostasis and tumorigenesis. LRIG2‐TG mice did not exhibit alterations in skin development or homeostasis but showed an interaction between LRIG2 and thrombospondin‐1, which is often involved in angiogenesis and tumorigenesis. However, during carcinogenesis, transgenic animals showed significantly increased tumor progression and a more rapid development of cSCC. This was accompanied by changes in the ERBB system. After a single TPA application, inflammation of the epidermis was enhanced during LRIG2 overexpression. In human skin samples, LRIG2 expression was identified in the basal layer of the epidermis and in hair follicles of normal skin, but also in cSCC samples. In conclusion, epidermal LRIG2 excess is associated with activated EGFR/ERBB4‐MAPK signaling and accelerated tumor progression in experimentally induced NMSC, suggesting LRIG2 as a potential oncoprotein in skin.

Abstract

Electrofuels are high‐energy compounds produced by the electrochemical reduction of compounds such as carbon dioxide or water. Microorganisms can act as biocatalysts for these reactions, during which they accept electrons either directly or indirectly from electrodes in bioelectrochemical systems (BESs). These microbes store this electrical energy by producing extracellular compounds instead of biomass. The electricity that drives this process may be harvested from intermittent renewable sources such as solar or wind. Thus, electrosynthesis could simultaneously sequester CO
2
and store renewable energy sources in designer chemicals, materials, or in convenient, high‐energy dense fuels for use in our transportation and electrical grid sectors. Butanol appears to be an ideal electrofuel target because it is considered a “drop‐in” fuel that can be used in our current energy infrastructure. Several challenges still face the production of electrofuels. The stability, structure, and conductivity of materials used as electrodes, the efficiency of electron transfer between these electrodes and microbes, and the diffusion of substrates (e.g., CO
2
) into and products (e.g., butanol) out of the microbes all need to be optimized for efficient microbial electrosynthesis. A complete life‐cycle assessment of the environmental impact of any electrofuel also needs to be conducted prior to its widespread use.
Tribocharging and the Triboelectric Series
Authors: Gooding Diana M. , Kaufman George K. 
Published: October 2019

Abstract

Tribocharging is a process in which materials contact one another, rub, and then separate, each with a resulting charge distribution that is generally uniform on a macroscopic level but may involve mosaics of both positive and negative charges on each material on the microscopic level. This process is familiar and applied extensively in processes such as electrophotography, energy harvesting, and self‐powered sensors, but it is not completely understood. The triboelectric series is a qualitative or semiquantitative ordering of materials according to their tendency to develop a positive or negative net charge when tribocharged against other materials. It is remarkable that, despite differences in surface preparation, modes of contact among materials, and laboratory conditions, triboelectric series generated by different groups remain largely consistent with each other. This article examines a variety of triboelectric series, discrepancies among them, and the possible competing mechanisms behind tribocharging and contact electrification in general. These mechanisms appear to include electron transfer, ion transfer, H
+
and OH
−
partitioning, bond dissociation, mechanoradical formation, chemical changes, and material transfer. Combinations of these mechanisms may occur simultaneously but at different rates, which may help to explain some of the inconsistencies among different triboelectric series.
Mechanochemistry
Authors: Desilets Elliot R. , Patel Priyanka D. , Kaufman George K. 
Published: October 2019

AbstractMechanochemistry is the use of mechanical forces to induce chemical changes in materials. In this article, we focus on the use of mechanophores – functional groups that react or that can be activated by mechanical force – as force sensors and as latent catalysts or cross‐linking complexes for self‐healing materials. We also examine the ability of single‐molecule force‐clamp spectroscopy, which is often based on atomic force microscopy, to provide details about the kinetics of reactions that can, in turn, lead to clearer understanding of the potential energy landscape of reactions and to sub‐ångström‐scale detail about the geometry of mechanochemical reactions. Mechanical force can reduce the activation energy barrier for thermochemical reactions or can alter the shape of the potential energy surface for chemical reactions, differently from heat or light alone, so that otherwise forbidden or slow processes may occur under mild conditions. Thus, mechanochemistry is a tool for chemical synthesis that can complement thermochemical, photochemical, and electrochemical synthetic routes.
Novel Inorganic Composite Materials for Lithium‐Ion Batteries
Authors: Liu Xinhua , George Chandramohan , Wang Huizhi , Wu Billy 
Published: October 2019

Abstract
Lithium‐ion batteries (LIBs) have revolutionized the way we interact with the world around us. This is in part due to their unrivaled energy density and stability relative to other energy storage chemistries such as lead‐acid, nickel–metal hydride, and nickel–cadmium batteries. Given the drive to reduce greenhouse gas emissions from road transport, LIBs have now transitioned from application in consumer electronics to be the most critical component for electric vehicles (EVs); however, improvements in energy and power density, cost reduction, and lifetime are still required. The key aspects of an LIB that define its performance are mainly the anode, cathode, and electrolyte, however development of the separator and current collectors are also key considerations. In the vast majority of commercially available LIBs, the anode consists mostly of graphite and the cathode mostly of layered transition metal oxides, with an organic electrolyte facilitating the lithium‐ion transport between the two electrodes. This article provides an overview of the state of the art in developing inorganic composite materials for LIBs and concludes by highlighting the current challenges as well as the potential opportunities in the field.

Published: October 2019

Abstract
The binary vanadium nitrogenase system (VnfHDKG) is a homolog of the well‐characterized molybdenum nitrogenase system. Vanadium nitrogenase catalyzes the ATP‐dependent reduction of dinitrogen to ammonia, but is also able to reduce other substrates such as carbon monoxide. The Fe protein (VnfH) serves as an electron donor for the VFe protein (VnfDKG) of vanadium nitrogenase. Electrons are transferred from the Fe protein via the P‐cluster to the catalytic center at the FeV cofactor, where substrate binding and reduction occurs. While the Fe protein of vanadium nitrogenase shows no significant deviations from its molybdenum nitrogenase homolog, VFe protein comprises an additional subunit VnfG with unknown function, and its metal clusters, P‐cluster and FeV cofactor, exhibit structural features that previously have not been observed in the homologous molybdenum nitrogenase system.
Polymer‐Derived Ceramics

Published: October 2019

AbstractPolymer‐derived ceramics (PDCs) represent a class of ceramics that are preparatively accessible from inorganic polymers (also called preceramic polymers). The synthesis and processing of PDCs from polymeric precursors have been shown within the past four decades to be an excellent way to design ceramics, which provides unique tools to control and tune structural features and consequently properties in PDCs. Thus, the molecular architecture and the chemistry of the preceramic polymers strongly correlate to the polymer‐to‐ceramic transformation characteristics as well as the structural features of the resulting PDC materials. By carefully designing the preceramic polymer, fine‐tuning of the chemical and phase composition of the resulting ceramics is possible, which results in unique microstructures and behavior thereof.The present article aims to give a brief introduction to the field of PDCs. Typically, an introduction of preparative tools to access PDCs from tailored inorganic polymers will be done. In addition, a critical consideration of the main structural features of PDCs will be given, with emphasis on the strong correlation between the nano/microstructure of the PDCs and the molecular architecture of their polymeric precursors. Also, various technologies being used to process PDCs in the form of porous materials, coatings, fibers, complex‐shaped monolithic parts, and so on will be introduced and discussed. Finally, some selected structural and functional properties (e.g., high‐temperature behavior, electrical properties, optical properties, and bioactivity) of PDCs will be highlighted and some emerging application fields in which PDCs may be highly suitable material candidates will be introduced.The present article does not intend to provide an exhaustive review of the activities from the past three to four decades in the field of PDCs, but rather to give a short overview of the particularities and the potential of this technology. The article refers in the section “Related Papers” to some excellent reviews and book chapters from the past 20 years, which address and summarize various aspects related to PDCs.
