studied, such conditions are: depressants and waxes differ by almost two times in the dielectric constants (Fig. 2). The charge q (coulomb) for the individual components of the mixture was calculated in a wide range of temperatures with the experimentally determined values of the capacitance and corresponding potentials using the following equation:
Myoglobin may cause a brownish discoloration of the urine. Hematuria may at times present with brownish-black specks in the urine, similar to coffee grounds. In some cases, like with a melanoma, the natural pigment melanin is passed out in the urine which has a brown color.
