The average activation energy of crystallization and the activation energy of glass transition were found to be 102.3 and 124.2kJ/mol, respectively. The Se75Te10Cd10In5 multi-component chalcogenide glass is more stable than Se75Te15Cd10 ternary glass. The non-integer

The diffraction efficiency has been increased by using potassium iodide and an iodine bleach process that converts a silver image into a dielectric image. An improvement in stability against the print-out effect has been observed by using two new developer compositions. Variation of the maximum diffraction efficiency against exposure to white light is shown graphically.

Adult male rats were divided into Sham, SCI and SCI + MF groups. BBB score, threshold of tail flick (TTF), tail flick latency (TFL) were noted to assess sensori- motor functions. In MF exposed rats, a statistically significant improvement was noted in BBB score, TTF and TFL by 2 nd , 1 st , 5 th wk respectively and their survival rate increased. This study suggests a significant recovery in complete SCI rats by chronic MF exposure.

Hand written RL still constitute the chief meansof fulfilling this need,[1,2,3] especially in the developingcountries, although other means are also available.[4] RLsin many ways are superior. They are modifiable, require least facilities towrite and have the advantage of documentation that may be of medico legalimportance. It has been proved that a good quality RL improves patient caresubstantially. [5] A good quality RLshould convey clearly the background information regarding the patient andreasons for which the request is made. This study was done to assess thequality of RLs in four tertiary care teaching hospitals, so as to find where westand, as an audit of RLs has never been done earlier from this subcontinent.

It was observed that the mixed phase barrier as thin as 2-5 nm can be designed to act both as robust copper barrier and as a copper direct plating layer by modulating the
