Further, the addition of 0.15%-m DPPD additive in JB5, JB10, JB15 and JB20 showed [NO.sub.x] emission reduction of 8.03%, 3.503%, 13.65% and 16.54% respectively, when compared to that of biodiesel blends without antioxidant additive [21].
Potent antioxidants, Trolox (1mM), resveratrol (50 [micro]M), and DPPD (2 [micro]M) also significantly decreased FLU-induced cytotoxicity and LPO and increased % MMP (Table 1) and GSH levels (Figure 5) in this system compared to control hepatocytes.
bovis BCG Pasteur strain 1173P2 was used as a source of DNA and as the parent strain for deletion of the dppd gene (GenBank accession number NC_008769, locus_tag BCG_0092) by homologous recombination.
In order to improve the training process and methodological skills to DPPD students in the experiment we proposed to achieve through action research, the relationship between the independent variables and the dependent structure are cause- effect related.
