Exploring the relationship between burnout, learning engagement and academic self-efficacy among EFL learners: A structural equation modeling analysis.

This study examined the role of learning engagement and academic self-efficacy in the feelings of burnout among English as a foreign language (EFL) students from China (N = 197). Three closed-ended scales were employed in the quantitative phase of this study to explore the relationship between the latent variables. Additionally, a hypothetical model was created and verified using Pearson's correlation analysis, structural equation modeling (SEM), path analysis, and mediating effect test.

Hydrophobic surface modification and characterization of melamine foam.

Superhydrophobic and oleophilic modification of commercial acoustic melamine foam (MF) was made in this study. The modification was carried out with chitosan (CHI) and silica particles (SiO), by using both a layer-by-layer-like approach (LbL) and dip coating technique. Subsequently, 1-octadecanethiol was used as a secondary modification agent.

Rare Cutaneous Manifestations of Erdheim Chester Disease: A Case Report and Literature Review.

Erdheim Chester disease (ECD) is a rare and complex non-Langerhans histiocytic systemic disease that affects multiple organ systems, including the bones, heart, lungs, and central nervous system. Fewer than 1,000 cases have been reported in the medical literature and dermatological manifestations of the disease are rare but can provide valuable diagnostic clues for this challenging disease. The cutaneous manifestations of ECD can take many forms, including nodules, plaques, papules, and xanthomas.

A state of art review on estimation of solar radiation with various models.

Solar radiation is free, and very useful input for most sectors such as heat, health, tourism, agriculture, and energy production, and it plays a critical role in the sustainability of biological, and chemical processes in nature. In this framework, the knowledge of solar radiation data or estimating it as accurately as possible is vital to get the maximum benefit from the sun. From this point of view, many sectors have revised their future investments/plans to enhance their profit margins for sustainable development according to the knowledge/estimation of solar radiation.
