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.
The excess protein in the urine often causes the urine to become foamy, although foamy urine may also be caused by bilirubin in the urine (bilirubinuria), retrograde ejaculation, pneumaturia (air bubbles in the urine) due to a fistula, or drugs such as pyridium.he excess protein in the urine often causes the urine to become foamy, although foamy urine may also be caused by bilirubin in the urine (bilirubinuria), retrograde ejaculation, pneumaturia (air bubbles in the urine) due to a fistula, or drugs such as pyridium.
