Authors: Singh, Hari; Kumar, Pradeep
Abstract: Mathematical models of tool life and surface roughness have been developed for turning En24 steel with titanium
carbide coated tungsten carbide inserts. 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.

Authors: Correia, Roberta; Magalhães, Margarida; Macêdo, Gorete
Abstract: Saccharomyces cerevisiae was assessed to increase protein levels of pineapple waste (PW) by solid state bioprocessing
(SSB) with and without nitrogen supplementation. 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.

Authors: Bora, Dilip Kumar; Nath, Rupanjali
Abstract: Nahar oil methyl ester (NOME) added (up to 30%, by vol) to neat diesel can be used in the existing engine without any
symptoms of undesirable combustion. This paper overviews the application of NOME in CI Engines by comparing its
performance and smoke opacity with conventional diesel fuel.

Authors: Ray, R C; Moorthy, S N
Abstract: Exopolysaccharide (EPS), pullulan, production by Aureobasidium pullulans strain MTCC 1991 was evaluated using
cassava starch residue (CSR), wheat bran (WB) and rice bran (RB) as solid substrates as well as carbon source, with or
without amendment of basal (mineral) medium. 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).
