Authors: Srinivas, T; Gupta, A V S S K S; Reddy, B V
Abstract: Optimum configuration for single pressure (SP), dual pressure (DP) and triple pressure (TP) heat recovery steam generator
(HRSG) is presented to improve heat recovery and thereby exergy efficiency of combined cycle. Deaerator was added to
enhance efficiency and remove dissolved gases in feed water. A new method was introduced to evaluate low pressure (LP) and
intermediate pressure (IP) in HRSG from local flue gas temperature to get minimum possible temperature difference in heaters
instead of a usual fixation of pressures. Optimum location for deaerator was found at 1, 3 and 5 bar respectively for SP, DP and
TP in heat recovery at a high pressure (HP) of 200 bar. Results also showed optimum pressure for air compression and steam
reheater by means of three categories of heat recovery.

Authors: Biswas, Rumpa; Mukhopadhyay, S N
Abstract: Ecobiotechnology using ecological engineering provides sustainable ecosystems that integrate society with its environment.
Rhizobium sp. growth in root of food producing plant or as an ecofriendly biofertilizer plays important role in microbe plant
interaction (MPI) systems. This study reviews importance of ecobiotechnology and aspects in rhizobial-non rhizobial MPI in
ecofriendly fertilizer function for industrial / commercial product formation.

Authors: Sharma, P L N; Muralikrishna, Dantu
Abstract: Cefadroxil carbonate (I) is synthesized from 7-amino desacetoxy cephalosporonic acid (II) condensing with mixed
anhydride that is obtained from reaction of para hydroxy phenyl glycine dane salt (III) with excess of ethyl chloroformate in
presence of excess of base, N-methyl morpholine.

Authors: Sengupta, Pinaki; Saikia, Pradip C; Borthakur, Prakash C
Abstract: Kaolin clay from Deopani deposit of Assam contains high amount of iron. Kaolinite particles, characterized by SEMEDX,
are pseudohexagonal and arranged in face-to-face pattern. Clay particles are coated with iron- and titanium-bearing
minerals, which can be separated by wet high intensity magnetic separator Titaniferrous impurities present as coatings on
kaolinite particles are difficult to remove by oxalic acid treatment.
