As soon as the COVID-19 pandemic appeared, the Moroccan education ministry decided to adopt distance learning (DL). Our target was to study the psychological impact of DL on Moroccan teachers during the pandemic. This cross-sectional study used an online questionnaire based on the Hospital Anxiety and Depression Scale. Among 148 responses, 64.9% were women, and the average age was 41.1±11.5 years. 79.1% participated in DL, 58.8% were required to acquire DL tools and 71.6% had never received DL training. Between the start and the end of confinement, we noticed a decrease in the motivation of teachers.36.2% had definite depressive symptomatology and 41.3% had certain anxiety symptomatology with a significant predominance in women. The frequencies of depression and anxiety were higher in those who had participated in DL, but the association was not significant. Depression was significantly frequent among teachers who were obliged to acquire tools to practice DL P=0.02, those who had never received training DL P=0.046, and those who were not satisfied with the situation P=0.03. We didn't find a direct association between DL and anxiety and depression, which the small sample size may explain, but we did find an association with the variables related to DL.

Cowpea is a seed legume, important for food and nutritional security in Africa's arid and semi-arid zones. Despite its importance, cowpea is experiencing a loss of genetic diversity due to climate change. Therefore, this study aimed to evaluate the genetic variability of 33 cowpea mutant collections using 20 SSR and 13 ISSR markers.

Crystal structure similarity is useful for the chemical analysis of nowadays big materials databases and data mining new materials. Here we propose to use two-dimensional Wasserstein distance (earth mover's distance) to measure the compositional similarity between different compounds, based on the periodic table representation of compositions. To demonstrate the effectiveness of our approach, 1586 Cu-S based compounds are taken from the inorganic crystal structure database (ICSD) to form a validation dataset.

The height of the water-conducting fracture zones (WCFZ) is crucial for ensuring safe coal mining beneath aquifers, particularly considering the secondary development of the WCFZ in upper seams due to repeated mining in close distance coal seams. Accurately predicting this height is essential for mine safety, groundwater protection, and optimal coal resource use. This study compiles extensive measured data from various mining areas in China to analyze the coupling relationship between the WCFZ development height and six influencing factors: mining thickness, mining depth, coal seam spacing, hard rock lithology ratio, and the slope length of working face.

Insects provide important pollination services for cops. While land use intensification has resulted in steep declines of wild pollinator diversity across agricultural landscapes, releasing managed honeybees has been proposed as a countermeasure. However, it remains uncertain whether managed honeybees can close the pollination gap of sunflower (Helianthus annuus L.

With the rapid advancement in technology, mobile learning has become an important educational model, particularly for health schools' students. This research aims to investigate the attitudes of health schools' students in Jordan towards mobile learning, as well as their perceptions of mobile learning advantages and disadvantages compared to the traditional face-to-face learning model.
