Overconfident results with the bivariate random effects model for meta-analysis of diagnostic accuracy studies by Furuya-Kanamori, Luis

“…Diaz found that the performance of the bivariate model deteriorates when between-study heterogeneity increases and the number of studies decrease.5 Our simulation studies found similar results—with moderate levels of heterogeneity (tau2 = 1), the coverage probabilities of Se, Sp, and the diagnostic odds ratio (DOR) with the bivariate model dropped below the nominal level.6 Diagnostic accuracy studies usually favor sensitivity over specificity, or vice versa leading to diagnostic 2 × 2 tables with one or more of the cells with low frequency or zero counts. …”

High-Rate Anaerobic Digestion of Waste Activated Sludge by Integration of Electro-Fenton Process by Feki, Emna

“…Following EF pretreatment, the pH, conductivity, soluble chemical oxygen demand (SCOD), and volatile fatty acids (VFA) increased to 7.5, 13.72 mS/cm, 4.1 g/L, and 925 mg/L, respectively. Capillary suction time (CST) analysis highlighted the dewaterability effect of EF on WAS, as demonstrated by the decrease in CST from 429 to 180 s following 30 min of pretreatment. …”

Short-term greenhouse emission lowering effect of biochars from solid organic municipal wastes by Rehrah D.

“…Two biochars produced from mixed materials at 300–500 °C for 2 h and used at 0.5–1% application rate performed the best in enhancing soil fertility parameters. A significant decrease in CO2 emission was observed in vials with soil–biochar mixtures, especially for biochars produced at 500 °C compared the corresponding raw materials which exhibited an exponential increase in the CO2 emission. …”
