“…The methodology proposed, however, is affected by some uncertainties concerning the temperature swing measured on the surface of the aluminum piston. The resulting piston temperature, for example, is considerably higher than that found by several other authors through numerical simulations and experimental tests performed with thermocouples [7,8], consequently the reliability of the different experimental techniques is still unclear. In view of the above-mentioned limits, there is not nowadays any specific experimental technique that can provide sufficient details concerning combustion chamber coating thermal behavior during engine cycles.…”

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 wear surface was measured after the test at 200 N loading force, 5 Hz frequency and high temperature (100°C ± 5°C) for 2 h. Each experiment was repeated at least three times. The choice of lubricating oil temperature is based on the actual lubricating oil temperature range (Harigaya et al , 2002; Rakopoulos and Mavropoulos, 2015). The lubricating oil and specimens were intermittently heated for many times to strictly control their temperature change.…”

“…Then 2 g of stearic acid and 3 g of oleic acid were added to the mixed solution. Finally, oil-soluble nano powder was obtained after stirring for 4 h at 80 • C and drying by centrifugation [24]. The results of FTIR measurement of modified CeO 2 and graphene powder are shown in figure 3.…”
