Study of VHF signals received from distant TV stations durig some major meteor shower periods

359-360VHF signals from the distant TV stations have been received and recorded on a strip-chart recorder. It has been observed that the strength of the received signals is more during the major meteor shower periods than during the non-shower periods. The strength of the signal received has been found to be increasing from Perseids (weak shower) to Geminids (strong shower)

Microwave thermolysis IV: Selective deprotection of MPM ethers using clay supported ammonium nitrate "clayan" in dry media

Selective deprotection of (4-methoxyphenyl)-methyl (MPM) ethers using clay supported ammonium nitrate under microwave irradiation is described. The use of expensive reagents and problems associated with slurry reactions are avoided

Microwave thermolysis: Part III — A rapid and convenient coupling of 2-naphthols in solvent-free condition^†

2615-2617A rapid and environmentally benign method for the coupling of 2-napthols is described using copper (II) acetonylacetonate under microwave irradiation in dry media. The procedure is very convenient and avoids the use of excess solvent for reaction

Microwave thermolysis VI : A rapid and general method for dethioacetalization using "clayan" in dry media

A variety of thioacetals, dithiolanes and dithianes are deprotected into their carbonyl compounds using clay supported ammonium nitrate "Clayan" under microwave irradiation. The present method avoids the use of toxic oxidants and excess of solvent

Not AvailableRice, grown on a wide range of soils with varying soil pH levels boron (B) availability, uptake and mobilization could be limiting hence may lead to lower productivity and rice yields has been tested at 11 locations on low yielding rice genotypes from, Initial Evaluation Trials (IET) of AICRIP viz.IET 20979, IET 21003, IET 21007, IET 21014, IET 21025 and Rasi as check variety. Active boron supplemented as foliar spray at anthesis stage at 0.2, 0.4 and 0.8 ppm. Grains with 1.20 (High density), and 1.06 (normal density) specific gravity (sp. gr.) and unfilled grains were determined. The results showed that application of boron resulted in increase in grain number (25-45) and reduced the number of unfilled spikelets. At majority of the locations, application of 0.4 ppm boron had resulted in significant increase in grain yield (4-8%). Cultures, IET 20979, IET 21007, and IET 21014 showed a positive response with the 0.4 ppm application at the majority of locations. © 2013 Copyright Taylor and Francis Group, LLC.Not Availabl
