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.
1 Red or pink urine: certain foods that are naturally red can cause these color changes in your urine. 2  Laxatives and some prescription drugs can also be the cause of red urine. 3  In some cases, blood in your urine stream can be a sign of a medical condition like an enlarged prostate, bladder stones or even kidney cancer.he yellow to amber color that normal urine has is due to a pigment called urochrome.
