An experiment was conducted to study the effect of porosity and grain size on thermo-physical parameter : heat storage coefficient of marble powder. Seven samples of marble powder having different grain size have been studied in the present paper. Sorting of different particle sizes were done through sieve analysis. The Heat storage coefficient (HSC) was measured by the plane heat source technique. It was possible to obtain a porosity range of 39 to 54 percent. For fine particles the HSC is low as compared with that for coarse particles. As the porosity increases the HSC decreases and beyond some larger values of porosity (say 54 percent) the change in value of HSC is less rapid..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
