TL;DR: In this paper, the dependence of dielectric constant of the BaLn2Ti4O12 (Ln=La, Pr, Nd, Sm) on packing fraction and nephelauxetic ratio is discussed.
Abstract: An attempt has been made to identify the optimum parameters for good dielectric resonator materials. The dependence of dielectric constant of the system BaLn2Ti4O12 (Ln=La, Pr, Nd, Sm) on packing fraction and nephelauxetic ratio is discussed. The reported dielectric data for this system were treated using the multiregression method.

TL;DR: In this paper, specific volume and ultrasonic velocity as a function of temperature are carried out in different natural oils and fats of plant origin and it is found that the mango kernel fat exhibits liquid crystal-like molecular order at T < 317 K. The variation of these parameters with temperature is also studied and the results are discussed critically.
Abstract: Investigations of specific volume and ultrasonic velocity as a function of temperature are carried out in different natural oils and fats of plant origin. From these studies it is found that the mango kernel fat exhibits liquid crystal-like molecular order at T < 317 K. Various ultrasonic parameters like adiabatic compressibility, molar sound velocity, molar compressibility, van der Waal's constant, and intermolecular free length are evaluated. The variation of these parameters with temperature is also studied and the results are discussed critically.
