Recent headlines have brought to the fore scary scenarios of what may happen when ordinarily used antibiotics lose their potency at a time when increases in resistance have been noticed among infective organisms. The news items also predict near astronomical number of deaths and losses to economies that might follow in the near future due to the failure of antibiotics. I believe that even cocktails of antibiotics lose their effectiveness over time. The only suggestion that has been put forth to overcome such disasters is to intensify research for the discovery of ever newer antibiotics.Full Text

Conversion of the kinetic energy of blowing wind into electric energy, employing wind turbines of modern design that use electronic controls for the production of steady AC power, is now well-established for utilizing a free, ecofriendly resource. Much information regarding the methods is available on the Internet. The possibility of employing captive wind power-generating systems for pumping freshwater from the western side of the Western Ghats, India, currently largely wasted into the Arabian Sea, in order to increase the water availability on the eastern side, needs to be seriously considered.Full Text

Configurational relationships among three, A, B and C, of the four possible isomers of trimethyl 1-methylcyclohexane-1,2,3-tricarboxylate imply that A and C should form a common C-3 enolate. While methylation of tritylsodium-formed A C-3 enolate gives one of the two possible meso forms and B C-3 enolate gives the racemic product, C does not form an enolate. 1H NMR-assigned preferred conformations of A and B show that their C-3 enolates form Na+ complexes stabilized by the C-1 syn, axial ester group, while the C-1 methyl in C hinders removal of the C-3 proton, thus preventing enolate formation. Early treatment of A enolate with methyl iodide leads to one of two possible meso methylated products, while late treatment gives the racemic form, also a product of B methylation. A gradual rise in C/A ratio is seen on protonating A enolate, though only a ring flip is involved, this phenomenon is attributed to the intervention of a slow Na+ deand re-complexation process. A unified explanation emerges under the premise that while the methylating agent approaches the enolate from the non-hindered face anti to Na+, the proton is guided by Na+ towards syn approach.Keywords

In the early 1960s, around the time Chanchal Uberoi joined the then Department of Applied Mathematics, the Indian Institute of Science (IISc) was passing through what may be called a transitional period. The IISc successfully provided not merely trained faculty over a crucial period in the history of higher Indian technical education, badly needed for the newly established institutes of research and technology, but also highlevel technical staff for the similarly new public sector engineering enterprises.Full Text
