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.
Red to pink discoloration of the urine is not a disease on its own. It is a symptom of an underlying disease. Even hematuria (blood in the urine) is a symptom. Other urinary related symptoms should also be noted such as 1  : Abdominal, perineal and flank pain. 2  Pain and burning during urination. 3  Foul odor of urine. 4  Cloudy urine.
