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.
According to the Kidney Cancer Association, hematuria is the most common sign of kidney cancer. If you have blood in your urine, you may see pink, brownish, or even a red discoloration. Often even a small amount of blood can cause a color change. But, sometimes there is such a miniscule amount of blood that only a lab can detect blood during a urinalysis.
