“…Table 3 reveals that at the same curing time, MK2 group shows the smallest porosity values compared with other three groups. Moreover, the porosity decreases with increasing curing time at the same MK content, which is attributed to the pozzolanic reaction between geopolymer, cement, and water [41]. Figure 6 illuminates that both UCS and E 50 of MK-based geopolymer cemented silty clay decrease with the increase of porosity and exhibit a linear correlation.…”

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.

“…The replacement levels presented are chosen such that they contain the optimums for mechanical strengths that are prevalent in the literature (10-20%). In addition, the range was chosen to include higher replacements because durability tends to increase systematically with replacement level [12,[23][24][25][26][27]. This concept of an 'optimum' replacement level is evoked because of the need to maximize performance and minimize cost.…”
