The evaluation of mechanical properties is essential to the performance guarantee of the material. However, this process is verycomplex for ceramic materials due to the variety of defects of such material. The aim of this work was to investigate the useof ultrasonic velocity measurements to the determination of mechanical properties in ceramic composites. To accomplish this,seven batches of alumina/zirconia, alumina/spinel and alumina/zirconia/spinel refractories were grinded, uniaxially pressed at100 MPa and sintered at 1550 oC. The evaluation of ultrasonic pulse velocity (UPV) was performed in commercial equipmentwith a transducer of 5 MHz. The results showed that the addition of zirconia and spinel to the alumina matrix increased thecompression resistance of the matrix in 75%. Furthermore, exponential equations relating mechanical properties and UPVwere found and it was observed the existence of an intrinsic relation between these parameters.

Several species of Passiflorahave been employed widely as a folk medicine because of sedative and tran-quillizer activities. In this study, we evaluate the effects on anxiety and memory process of two popularly used Passifloraspecies. To this aim, male Wistar rats (weighing 250300 g) were intraperitoneally injected with the aqueous extract of Pas-siflora alataor Passiflora edulis(25, 50, 100, or 150 mg/kg; single injection) 30 minutes prior to the elevated plus-maze test,inhibitory avoidance test, or habituation to an open-field apparatus. The effects of both species of Passiflorawere comparedwith that of diazepam (1 mg/kg), a standard anxiolytic drug. Our findings revealed that, similar to diazepam, the treatmentwith P. alata(100 and 150 mg/kg) and P. edulis(50, 100, and 150 mg/kg) induced anxiolytic-like effects in rats. Memorywas not affected by the treatment with any dose of P. alataor P. edulis, but diazepam disrupted memory process in rats. Phy-tochemical analysis showed that the content of flavonoids of the aqueous extract of P. edulisis almost twice that of P. alata.These differences in contents of flavonoids could explain the lower active doses of the aqueous extract of P. edulisin induc-ing anxiolytic-like effects compared to P. alata. In conclusion, our findings suggest that, distinct from diazepam, the aque-ous extract of both species of Passiflorainduced anxiolytic-like effects in rats without disrupting memory process.

Driven by the need for remote learning, the COVID-19 pandemic led to the rise of use of videoconferencing tools. Scholars began noticing an emerging phenomenon of feeling tired and exhausted during virtual meetings. This study determined the predictors of videoconference or Zoom fatigue among nursing students in a large, private, non-sectarian university in the Philippines. This cross-sectional online survey involves 597 nursing students in the Philippines using the Zoom Exhaustion and Fatigue Scale. Multiple linear regression analysis was used to examine predictors of videoconference fatigue. Results indicated that nursing students experienced high levels of videoconference fatigue. Gender, self-reported academic performance, Internet connection stability, attitude toward videoconferencing, frequency, and duration of videoconferences predicted videoconference fatigue. The regression model explained 25.3% of the variances of the videoconference fatigue. Videoconference fatigue is relatively prevalent and may be taking its toll on nursing students. Developing strategic interventions that can protect or mitigate the impact of fatigue during virtual meetings is needed.
