“…The mass per unit area can be increased by increasing thickness or by selecting a more dense material. However, this study found otherwise and similar observations were found in a closed-cell aluminium foam [4], [5].…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…6 However, aluminum foams are expensive and their sound reduction index is small at low frequencies. 7 Moreover, the manufacturing of glass foams and Portland cement at high temperatures consumes a significant amount of energy and leads to the emission of huge amounts of carbon dioxide, which is the main cause of the greenhouse effect. 8 Consequently, it is necessary to develop an inexpensive, fire-resistant, energy-saving and environmentally friendly acoustic and thermal insulting material to replace these existing ones.…”

“…Observation of these three stages revealed high and wide platforms in the uniaxial compression experiments of CAF, with considerable energy absorbed under constant stress states during the compression processes. Energy consumption capacity has been found to increase with the extension of this platform [18][19][20]. In experimental compression-shear tests of CAF under quasi-static conditions, Xueyan et al [21] observed that an increase in the pore size of CAF increased the yield stress under the same density conditions.…”
