The main objective of the present work is to evaluate the stochastic seismic response of a large-span continuous girder high-speed railway (CGHSR) bridge subjected to fully non-stationary seismic excitation.The stochastic ground motion is determined by a fully non-stationary ground acceleration model with both the time-varying intensity and frequen
ealisboa.com Conceptual change can be a challenging process, particularly in science education where many of the concepts are complex, controversial, or counter-intuitive.Yet, conceptual change is fundamental to science learning, which suggests science educators and science education researchers need models to effectively address and investigate co
The Covid-19 pandemic has strongly shown the uncertainty and complexity of our lives.We are involved and we participate in questioning our consolidated life models and in the experimentation of new political and economic models, involving different actors, from the governments to the communities or virtual societies.Technologies have definitely an
Astrocytes, comprising the primary glial-cell type, are involved in the read more formation and maturation of synapses, and thus contribute to sustainable synaptic transmission between neurons.Given that the animals in higher phylogenetic tree have brains with a higher density of glial cells with respect to neurons, there is a possibility that the
