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.
Blood in the urine can be caused by bleeding anywhere in the urinary tract and may result from inflammation, infection, kidney disease or failure, kidney stones, injury, cancer, or bleeding disorders. Blood in the urine may turn it brown, red or pink, or may only be visible under the microscope.
