Response surface methodology (RSM) has been applied for developing the models in the form of multiple regression equations correlating dependent parameters, tool life and surface roughness, with cutting speed, feed rate and depth of cut, in a turning process. The second order response surface was found suitable for present work. The central composite rotatable design was used to plan the experiment.

PW (10 g) was inoculated with S. cerevisiae. Optimum protein content (22% dry basis), which is 3.5-fold the original protein content, reached at 48 h of incubation when 0.25% (NH₄)₂SO₄ was added to medium. Thus, fermented PW can be successfully converted into a protein-rich feed by SSB.

This paper overviews the application of NOME in CI Engines by comparing its performance and smoke opacity with conventional diesel fuel.

EPS production was negligible without amendment of basal medium on all tested substrates but with the supplementation of basal medium, production of EPS was maximum on CSR (27.5 g. kg⁻¹ substrate), followed by WB (19.5g.kg⁻¹ substrate) and RB (2.4g.kg⁻¹ substrate).
