An Experimental Investigation on Trench Isolation Techniques for Vibration Control

One of the methods of controlling vibration amplitudes at source is by adopting active isolation techniques. Trench barriers are identified as methods of isolation. This paper deals with series experimental investigation carried out on block vibration tests with active isolation trench barriers. The parameters like depth of embedment, dimensions of trench, fill material in trench etc., are studied by carrying out the block vibration test in field. The results are analysed to identify the influence of those parameters

Overcoming Incompatibility In Wide Crosses

Wild species of crop plants attract much attention as a valuable gene pool. A few successes in improving crop plants have resulted from crossing wild taxa with cultivated ones. Several other taxa are not crossable with their cultivated relatives and are therefore unavailable for sexual gene transfers. Methods for breaking these barriers to interspecific hybridization and hybrid production have been develope

Kinetics of thermal decomposition of some metal oxalates

The thermal decomposition kinetics of oxalates of ZnII, NiII and ThIV have been studied in air by isothermal and non-isothermal thermogravimetry. The isothermal kinetic results suggest that the mechanism of decomposition of the zinc compound involves rapid nucleation followed by two dimensional growth in the acceleratory region, while in the case of thorium oxalate, the initial nucleation occurs by a chain mechanism on the surface of the reactant followed by the growth of the product from the surface towards the interior. The results on nickel oxalate could not be interpreted in an unambiguous manner. The activation energy and the frequency factor obtained from TG curves compare well with those obtained from the isothermal method. The activation energies for the dehydration of these oxalates have also been evaluated from the thermogravimetric curves
