A system for carrying electrical energy in connections in underground cables. The both layers are formed by a thermoplastic material with predetermined basis weight, and Young’s modulus. The application further provides methods of using the disclosed compounds and compositions to activate PPAR\u03b3, activate GPR120, inhibit inflammation, and treat conditions responsive to PPAR\u03b3 modulation, conditions responsive to GPR120 modulation, and metabolic disturbances such as diabetes. Another aspect of the invention relates to methods of measuring and aligning the component parts of the drum assembly. Decomposed carnallite liquor produced is reacted with hydrated lime for preparing CaCl2 solution and high purity Mg2 having low boron content.
