| Abstract | The photoacoustic dispersive anomalies of glass transitions were measured by utilizing the gas-microphone method in propylene glycol and glycerol, which are typical materials of the fragile liquid. The temperature dependence of the mean relaxation time was obtained. It was analyzed by the Vogel-Tammann-Fulcher law. It was found that the obtained parameter is in agreement with the values determined by the measurements of the dielectric dispersion reported previously. The distribution of the relaxation time was analyzed by the use of the Cole-Cole plot, and the parameter of the Davidson-Cole formula was determined. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
