We test the following hypotheses: 1. Crises show a GDP effect for peak countries (i.e., the contribution factor decreased after crisis). 2. Crises show a SC effect for peak countries. 3. Crises show a SC effect for non-peak countries. 4. Crises show a GDP effect for non-peak ...

(w/w) biochar) to 1.2±0.06 mg kg À 1 dry soil and 2.7±0.02 mg kg À 1 Statistical analyses In order to identify statistically significant biochar effects, a univariate analysis of variance (ANOVA) with the 'least significant difference' post hoc test (Po0.05) was performed using ...
The test vehicles in most studies are older technology. Only one study was found that measured 2010 certified liquified natural gas (LNG) RTs under real-world conditions (Misra et al., 2017). Further, no study was found regarding front-loader CNG refuse trucks. The real-world duty cycles, ...
